Quality of life
Multiple Sclerosis (MS) is a common neurodegenerative disease, which often has a devastating effect on physical and emotional wellbeing of people with MS (PwMS). Several studies have shown positive effects of physical activity (PA) on disability, health related quality of life (HRQOL), and other outcomes.
However, many studies include only people with mild disability making it difficult to generalise findings to those with moderate or severe disability. This study investigated the associations between PA and HRQOL, relapse rate (RR), disability, and demographic variables in PwMS with varying disability.
Methods: Through online platforms this large international survey recruited 2232 participants with MS who completed items regarding PA, MS and other health characteristics.
Results: PwMS who were younger (p <.001), male (p = 0.006), and with lower body mass index (BMI) (p <.001) undertook more PA, which was associated with decreased disability (p <0.001) and increased HRQOL measures (all p <0.001).
For the subsample of people with relapsing-remitting MS, PA was associated with a decreased RR (p = 0.009). Regression analyses showed that increased PA predicted clinically significant improvements in HRQOL while controlling for level of disability, age and gender.
More specifically, increasing from low to moderate and to high PA increased estimated mean physical health composite from 47.7 to 56.0 to 59.9 respectively (25.6% change), mental health composite from 60.6 to 67.0 to 68.8 (13.5% change), energy subscale from 35.9 to 44.5 to 49.8 (38.7% change), social function subscale from 57.8 to 66.1 to 68.4 (18.3% change), and overall QOL subscale from 58.5 to 64.5 to 67.7 (15.7% change).
Conclusions: For PwMS, regardless of disability level, increased PA is related to better HRQOL in terms of energy, social functioning, mental and physical health. These are important findings that should be taken into consideration by clinicians treating PwMS.

Individuals with multiple sclerosis (PwMS) often have mobility impairments that may lead to falls and limitations in activities. Physiotherapy interventions that could improve mobility typically take several weeks. Balance-based torso-weighting (BBTW), a system of strategically placing light weights to improve response to balance perturbations, has resulted in immediate small improvements in clinical measures in PwMS, but changes in spatiotemporal gait parameters are unknown. The purpose was to examine the effects of BBTW on gait parameters in PwMS and healthy controls. This study is a non-randomized controlled experiment. The study was comprised of 20 PwMS and 20 matched healthy controls.
Individuals with multiple sclerosis walked on an instrumented mat at their fastest speed for three trials each in two conditions: without BBTW then with BBTW. Healthy controls walked in both conditions at two speeds: their fastest speed and at velocities equivalent to their matched PwMS. Averaged gait trials showed that, with BBTW, PwMS had significantly increased velocity (p = 0.002), cadence (p = 0.007) and time spent in single-limb support (p = 0.014), with reduced time in double-limb support (p = 0.004). Healthy controls increased velocity (p = 0.012) and cadence (p = 0.015) and decreased support base (p = 0.014) in fast trials with BBTW; at matched velocities, step length (p = 0.028) and support base (p = 0.006) were significantly different from PwMS. All gait variables in healthy controls at fast speeds were significantly different from PwMS walking at their fastest speeds.
All participants displayed increases in gait velocity and cadence during fast walk with BBTW. Improvements in time spent in single-limb and double-limb support by PwMS with BBTW may reflect greater stability in gait. Future research might ascertain if these immediate improvements could enhance effectiveness of longer-term physiotherapy on functional mobility in PwMS.

• This study presents patient perspectives on the impact of relapse early in MS therapy.
• Patients often do not report relapses to healthcare professionals.
• Relapse affects patients? finances and ability to work and undertake routine daily tasks.
• Despite relapse, patient persistence with disease modifying therapy is good.
• Reporting and documentation of relapses need improvement if relapse reduction is to remain a key goal of treatment.
Background: The fixed, progressive disability associated with late Multiple Sclerosis (MS) is known to have a major impact on patients and their families, but the impact of relapse earlier in the disease course is less well documented, particularly from the patient?s perspective. This study aimed to understand the effects of relapse for people with MS (PwMS), focussing on the years immediately after starting disease modifying therapy (DMT) when experience of a relapse may particularly influence a patient?s opinions of their disease and its therapy.
Methods: This was a multi-centre, retrospective, observational research study, recruiting patients from 7 UK NHS Hospital Trusts. Consenting patients with relapsing-remitting MS (RRMS), who had started a DMT more than 36 months before screening, were sent a study questionnaire. Data on MS relapses and treatments over 3 years were collected simultaneously from medical records.
Results: One hundred and three patients completed the questionnaires. Relapses were under-reported to health care professionals, with 28% of respondents failing to report their most recent attack and 46% declaring they had failed to report an attack in the past. During their most recent relapse, 67% of those in paid employment reported taking time off sick, 48% reduced working hours temporarily, and 41% worked reduced hours and took time off sick. Sixty-six percent required additional support to undertake routine daily tasks during their most recent relapse. A range of effects of relapse which cannot be measured in financial terms were also reported, including effects on physical abilities, mental health and family roles and relationships.
Conclusion; This contemporary UK-based study provides an insight into the experience of relapse early in the treatment of RRMS from the patient perspective. The comparison of documented patient reported relapses reveals some deficiencies in the recording of relapses which is important to address in view of the reported impact of individual relapses, and emphasises relapse reduction as a worthy treatment aim.

More common than anyone suspects, the unspoken issue of sexual dysfunction affects more than half of the MS population.
Researchers delved into the private lives of men with multiple sclerosis (MS) in a recent study and discovered that sexual dysfunction is a common MS complication. Although it’s a topic patients may be reluctant to discuss with their neurologists, they should be aware that intimacy problems are often treatable.
Scientists from the Institute of Psychiatry and Neurology in Warsaw, Poland, interviewed 67 men with MS who were members of the National MS Center. The participants also filled out questionnaires and underwent neurological evaluations, all in an attempt to measure their sexual satisfaction.
Of those 67 men, researchers found that more than half complained of erectile dysfunction (ED), roughly a quarter reported decreased interest in sex or had issues reaching climax, and nearly a fifth had difficulty with ejaculation. These results didn’t seem to depend on the patient’s age, the amount of time since his diagnosis, or his level of disability.
A 'Wall of Silence'
The researchers concluded that sexual dysfunction "is highly prevalent but commonly overlooked in MS patients and has a significant impact on their sexual quality of life.” Despite these widespread issues, the researchers found that only 6 percent of the study participants had spoken about these problems with their doctor.
The discrepancy between the number of men who suffer from sexual dysfunction and those who report it to their doctor is probably due to the taboo nature of the topic.
Most likely, the subject doesn't come up, according to Megan Weigel, DNP, ARNP-C, MSCN, in an interview with Healthline, "because sexual dysfunction is a sensitive issue both for the person with the problem and the healthcare provider. However, it is possible that people with MS may not know it can be a symptom of the disease."
But if patients can put aside their discomfort long enough to have a frank conversation with their doctor—dropping the wall of silence—it may be possible to treat the problem.
Sexual Dysfunction Isn’t Just for Men
In an earlier study, the same group of researchers looked at sexual dysfunction in women with MS. While the researchers identified real issues faced by more than three quarters of the patients studied, only 2.2 percent of these women ever told their doctors about their sexual difficulties.
Among the problems women reported were lack of desire, decreased sensation in the genitals, poor lubrication, and an inability to climax. The study found that sexual dysfunction was "less likely in women who assessed their relationship positively but more common in older patients and those who had a positive history of depression.”
In the case of both male and female sexual dysfunction, the problem appears to be widely under-reported and overlooked by medical professionals.
Communication Is Key
MS is a disease that compromises the central nervous system, and sexual side effects are common among patients. Neurologists are trained to treat all aspects of the disease, including sexual complications. Understanding that it is a side effect of MS, and not due to any personal inadequacy, should quell the anxiety patients feel about discussing intimacy problems with their doctor.
The researchers stressed that neurologists should put more emphasis on sexual dysfunction when they examine their patients and have better screening tools in place. Doctors can treat problems only if they know symptoms exist, so, for patients, speaking up is imperative.
Sexual Dysfunction Defined
According to a 2009 article in MSFocus written by Frederick W. Foley, Ph.D., there are three types of MS-related sexual dysfunction: primary, secondary, and tertiary.
Primary dysfunction is caused by damage to the nerves from MS. Signals from the brain can no longer travel to parts of the body involved in sexual activity. Genital numbness is a classic example of primary dysfunction.
Examples of secondary dysfunction are bowel or bladder issues, spasticity or hand tremors—anything that indirectly complicates intimacy.
The tertiary variety of dysfunction is caused by the emotional aspects of MS—psycho-social or cultural issues that can impact a person’s feelings about sex. Body image, mood swings, and self-esteem can all affect intimacy. The changing dynamic of relationships—when life partners become caregivers, for example—can also play a role in tertiary sexual dysfunction.
Improving Sexual Quality of Life
Patients need not suffer in silence. "There are several ways to help men with MS who suffer from ED," Weigel said. "Medications like Viagra, Cialis, and Levitra may be helpful. If they are not, there are injectable medications and mechanical devices that may be required." For women, lubricants such as K-Y Jelly can help with vaginal dryness, and exploring new techniques for arousal might address loss of libido.
"Sexual dysfunction can be caused by side effects of medications like antidepressants, muscle relaxants, pain medications, and anti-seizure drugs; other medical conditions that affect small blood vessels, like diabetes and hypertension; and psychological issues, like loss, role changes, fear of failure, depression, and anxiety," Weigel said. "Timing of medication dosing, and timing of sexual activity so that it occurs at the time of day with the least fatigue can be helpful. Counseling and sex therapy are also very useful in conquering physical and emotional problems related to sexual dysfunction."
"Remember that as healthcare providers, we should be able to listen with a nonjudgemental, open ear in a nonthreatening environment to sensitive issues," Weigel added. She also suggests that patients write down their concerns and give the list to their doctor. "This could result in an open discussion that would put the person more at ease," she said.

Multiple sclerosis (MS) can be devastating to younger individuals given that it usually strikes during the peak productive ages of 20 to 50 years. When patients with MS are confronted with this potentially debilitating condition and the recognition that no cure for MS currently exists, their quality of life (QOL) can suffer.
Recent research indicates that patients with MS report QOL that falls more than 1 standard deviation below that of the general population (mean health state score 59.7 ± 22.4 for patients with MS versus 82.5 for the general population).1 In this registry study of 4516 patients with MS, health-related QOL ranked poorly, particularly in men, older individuals, people with a long duration of MS, and those with a progressive form of the disease. Among the total cohort of MS patients, about 83% reported difficulties with usual activities, 76% indicated problems with pain or discomfort, 76% struggled with mobility, and 58% reported problems with anxiety or depression.
Although disease-modifying therapies hold promise for reducing MS symptoms, preventing relapse, and delaying disease progression, many of these agents produce little improvement in QOL.2,3 This suggests that either better disease-modifying therapies or adjunctive treatments may be needed to improve specific MS symptoms in order to positively influence QOL.
Two comorbid conditions that are particularly relevant in individuals with MS and which are amenable to symptomatic treatment are pain and depression. “Researchers from our team and others in the field have consistently noted a strong association between depression and pain severity, but elements of the pain-depression relationship haven’t been fully researched, particularly in individuals with MS,” said Kevin Alschuler, PhD, acting assistant professor in the Department of Rehabilitation Medicine at the University of Washington School of Medicine in Seattle.
To better address this issue, Dr. Alschuler and colleagues surveyed 161 individuals with MS to evaluate the prevalence of pain and depression using a variety of methods for defining these conditions.4 The findings were striking: “As many as 1 in 5 patients with MS experience both pain and clinically significant depression, and 42% to 78% of patients with MS experience pain, depression, or both,” Dr. Alschuler noted.
The results not only reinforce the importance of considering both pain and depression in patients with MS, they also lend insight into the pattern of these comorbidities. For example, “When depression was present, pain was highly likely to also be present. Relatively few patients in our sample had depression without also having pain,” said Dr. Alschuler, who also found that patients with comorbid depression visited medical providers more frequently for pain relief and used a greater number of pain treatments than patients without comorbid depression.5
Recognizing that a large treatment gap in QOL exists for patients with MS is half the battle; the other half is taking proactive measures to address the situation. Dr. Alschuler believes that, in addition to managing symptoms and delaying disability progression, assessing and promoting patient QOL should be a primary goal of MS treatment.
“We’re very interested in having our research impact clinical practice and, in fact, believe that it has already helped us take our first steps in that direction,” said Dr. Alschuler, whose research team recently received grant funding for a study that seeks to improve the model of care for depression and pain in patients with MS.
This new study will aim to compare the delivery of standard care versus collaborative care to 200 outpatients with MS who have depression, chronic pain, or both. Under the collaborative care approach, a care manager—that is, a nurse supervised by expert physicians, psychiatrists, and psychologists—will coordinate and provide evidence-based therapy for depression and pain that matches the patient’s goals and preferences. Although this strategy has proven successful across a variety of ailments, it has never been evaluated in patients with comorbid MS, pain, and depression.
“We’re particularly excited about the specific care model we’re testing, as we believe that it would be feasible for the model to be implemented in standard clinical practice if our study supports its use,” said Dr. Alschuler.

Access to treatment and services varies remarkably for EU citizens diagnosed with multiple sclerosis, depending on which country they live in, according to a survey by the European Multiple Sclerosis Platform (EMSP).
The MS Barometer 2011, which has measured and compared wellbeing and quality of life for people living with multiple sclerosis in 33 European countries, including 26 EU member states, shows huge disparities in terms of access to treatment, therapies and employment.
While Germany overall came on top as the best country for people with multiple sclerosis in the EU, scoring 207 points, ahead of Sweden (184 points) and Austria (178), Bulgaria scored the fewest points (62 points), followed by Poland and Lithuania with 87 and 88 points, respectively.
Maggie Alexander, CEO of the EMSP, told EurActiv that the impact of having a condition such as multiple sclerosis is much more severe in countries that fail to provide the optimal treatment and services to help people maintain control of their disease, including remaining economically independent and fully participate in society.
“The EMSP will continue to drive forward effective collaborations with EU institutions and all those that share our commitment to escalate progress in the vital areas of research, healthcare and employment,” Alexander said.
“This will help to reduce the health inequalities that are faced by far too many of the nine million people in Europe living with neurodegenerative conditions,” EMSP’s CEO continued.
Multiple sclerosis is a potentially disabling disease. It strikes the white matter of the brain and spinal cord and affects the rest of the nervous system. According to the EMSP, multiple sclerosis has great consequences for society as more than one million people in Europe are affected indirectly through their role as carers and family members.
Younger people between 20 and 40 are the ones who are the most often diagnosed with multiple sclerosis. Women are diagnosed twice as often as men.
More than 120,000 people with multiple sclerosis live in Germany. This is more than in most other European countries. The EMSP said that Germany, with its long tradition of universal healthcare, provides strong protection for all disabled people.
When it comes to multiple sclerosis, the treatment in Germany is carried out by inter-disciplinary teams. The full cost of disease-modifying drugs is reimbursed by government without limits on duration of treatment and the treatment of symptoms is also fully covered. People also have unlimited access to rehabilitation.
Another positive fact about Germany is that good access to new medication and that specialised palliative care are offered while the country also scores high on research.
Germany also scores best in employment and job retention for people with multiple sclerosis, the barometer confirmed. This is due to protective legislation and flexible working conditions. 32% of people with MS are employed full time and 13% part time. An early retirement pension fund also exists.
Restricted access to care
At the same time, an EU country with low government spending on healthcare, like Poland, provides poorer treatment and quality of life for people with multiple sclerosis.
Poland has a very high ratio of people with multiple sclerosis, 120 in 100,000 people affected. Around 500 people are newly diagnosed each year. However, access to disease-modifying treatment provided is restricted. For example, after five years, access is transferred to the next person on the waiting list.
And though access to therapy for treating symptoms is relatively high, state reimbursement is modest with less than one-third of people having access to rehabilitation services.
Concerning employment, Poland fairs well due to strong laws against discrimination in the workplace. The country also scores well on empowerment of people with multiple sclerosis.
Lacking EU response
In September 2012, the European Parliament passed a written declaration initiated by the Romanian MEP Petru Luhan from the European People’s Party (EPP) on tackling multiple sclerosis in the EU, endorsed by more than 400 MEPs, calling for the European Commission and member states to enhance equal access to quality care.
But this commitment was not followed up with any concrete measures to reduce the inequalities for people with multiple sclerosis across the EU.
The EMSP said that the EU should live up to its declaration by addressing four major problems. First of all, the EU needs a closer scientific collaboration and comparative research on multiple sclerosis.
Secondly, there should be equal access to treatment and flexible employment policies for people with chronic neurological disorders such as multiple sclerosis.
Thirdly, there should be equal access to quality care, the EMSP said, for example by using certified educational training tools and lastly, collection of patient data at national level is encouraged in order to compare best practices.
EurActiv has asked Luhan as well as other MEPs, who have previously been involved with issues related to multiple sclerosis, for an interview. Unfortunately, they all declined.

Measuring the walking speed of multiple sclerosis patients can help doctors assess progression of the disease and the severity of disability, a new study suggests.
In people with multiple sclerosis (MS), the immune system damages the protective myelin sheath around the body's nerves.
"We already know that the timed 25-foot walk test is a meaningful way to measure disability in MS," study author Dr. Myla Goldman, of the University of Virginia in Charlottesville, said in a news release from the American Academy of Neurology. "Our study builds on that research by providing a clearer idea of how walk time can provide information about how a person's disease progression and disability impacts their everyday activities and real-world function."
The study included 254 MS patients who were timed as they walked 25 feet. Those who took longer than 6 seconds to walk that distance were more likely to be unemployed, to have changed jobs because of MS and their walking ability, to use a cane, and to require help with daily activities such as cooking and house cleaning.
For example, 59 percent of those who took less than 6 seconds to walk 25 feet were employed, compared to 29 percent of those who took longer than 6 seconds. Just 43 percent of the faster walkers had changed jobs because of MS, compared to 71 percent of slower walkers.
Patients who took 8 seconds or longer to walk 25 feet were more likely to be unemployed, to use Medicaid or Medicare, be divorced and use a walker. They were more than 70 percent more likely to be unable to perform daily activities such as house cleaning, grocery shopping, laundry and cooking, according to the study published online Oct. 30 in the journal Neurology.
Based on the study findings, "we propose that a timed 25-foot walk performance of 6 seconds or more and 8 seconds or more represent meaningful benchmarks of MS progression," Goldman added in the news release.

A new UK study has revealed that people with MS do not always report their relapses despite the domino effect on their health, financial security and support networks. The study also uncovered that inadequate patient reporting of relapses may bias views of clinicians on the adequacy of disease modifying treatments. Preliminary findings from the study presented at the 29th congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) have shown a worrying trend towards MS health professionals accepting a level of ongoing MS relapses as inevitable without considering alternative treatments, as well as significant underreporting of relapses by patients. Nearly half (46%) of respondents had experienced a relapse but did not report it.
The Novartis funded MS Pathways study led by Dr Martin Duddy, consultant neurologist at Royal Victoria Infirmary, Newcastle found that over a quarter of people had not reported their most recent relapse, despite two out of three employed respondents having to take time off work and 66% needing to call on their support network for help with simple daily tasks. The financial burden of relapses was striking, with a third of respondents reporting a reduction in family income, nearly half (48%) of respondents had to temporarily reduce their hours, whilst 8% had to permanently reduce their hours and 10% had to give up work entirely.
Dr Martin Duddy commented; "Even minor relapses have an impact on a patient's physical and psychological well being, as well as their financial well being. The uncertainty of not knowing when the next relapse might come can be a strain for many people. We need to have a clear picture of whether or not patients are having relapses, as they have an important role in assessing whether they need treatment and whether that treatment is working."
The main reasons cited for underreporting were that patients considered their symptoms too mild or did not feel there was anything healthcare professionals could do.
Over the past few years clinical opinion regarding relapses has begun to change, with a clear shift away from unquestioning acceptance of relapses, towards all relapses being considered a sign of clinical activity that merit discussion and action. The MS Pathways study provides further evidence to support the need for better systems to ensure full reporting of relapses so that MS healthcare professionals can make informed treatment decisions with their patients.
Amy Bowen, Director of Service Development at the MS Trust commented; "The MS Trust welcomes this important study. It is crucial that we improve reporting of relapses and ensure that people with MS receive the right information about recognising a relapse and the treatment that is available to help them manage its impact. No one should be coping with the burden and disruption of a relapse without the support of their MS team, particularly their MS specialist nurse."
MS is the most common neurological condition affecting young adults in the UK. It is estimated that over 100,000 people in the UK have MS - relapsing remitting MS (RRMS) is the most common form, affecting 80% of people.
Relapses are unexpected and can happen at any time. The impact of a relapse can last for weeks or months and the symptoms may range from loss of vision to spasm and mobility problems. Such symptoms can have a huge impact on family life, work and social activities, and the unpredictable nature of relapses can make it difficult for a person with MS to plan ahead with confidence.
The number of relapses experienced (annualised relapse rate) is one of four key measures used to assess the progression of a patient's MS, in addition to physical disability, lesion activity on MRI and brain volume loss as measured by MRI.
A team of MS healthcare professionals, including Dr Duddy are working together with Novartis to develop educational materials to support more effective reporting of relapses.

Multiple sclerosis (MS) patients rate their quality of life lowest with respect to their relationships with family and friends and activities of daily living, according to new research from Kantar Health, a leading global healthcare advisory firm.
MS patients’ overall quality of life is similar across all patient groups, with untreated patients having a higher quality-of-life score than their treated counterparts, especially those treated with non-disease-modifying drugs. While untreated patients have fewer issues with activities of daily living, they claim their health problems have affected their relationships with family and friends to a similar degree as treated patients. Apart from these categories, untreated patients score higher on other dimensions such as rejection, coping, symptoms and psychological well-being.
“MS is a chronic disease that progresses at different rates depending on the patient,” said Rose Lorenzo, director of research at Kantar Health. “While untreated patients have been diagnosed with their condition for an average of 20 years, slightly more than half assess their degree of disability as normal to mild. Therefore, they face fewer problems with rejection and in coping with their disease. However, the data suggest that current treatments for MS still are not meeting patients’ needs, and new treatments need to improve patients’ quality of life and overall outcomes.”
MS-related quality of life was assessed with the Multiple Sclerosis International QoL questionnaire. More than 950 MS patients answered questions in nine domains, and quality of life was measured on a 100-point scale based on responses to these questions.
About Kantar Health Syndicated Patient Studies
The study’s results were drawn from the Multiple Sclerosis Syndicated Patient Study, a nationally representative, self-administered survey. Topics covered include the health status, attitudes, behaviors and patient-reported outcomes among adults diagnosed with MS. Kantar Health conducts syndicated studies across several therapeutic areas in the U.S.

Background: Spasticity is a common symptom in multiple sclerosis (MS) that increases the burden of disease. This study investigated the relationship between the degree of spasticity and patients' health-related quality of life (QoL).
Methods: Epidemiological, multicentre, cross-sectional study in patients with MS spasticity. The SF-12 questionnaire was used to assess QoL. The modified Ashworth scale and a 0-10 Numerical Rating Scale (NRS) were used to assess spasticity severity.
Results: Data were analysed for 409 MS patients with spasticity from 53 neurology clinics in Spain. Mean age was 46.4 (±11.0) years; 62.4% were women. Most patients had relapsing-remitting MS (42.1%) or secondary progressive MS (43.9%). Mean time since MS diagnosis was 12.5 (±7.4) years and mean time since first spasticity symptoms was 6.1 (±4.8) years. A total of 71.3% of patients were being treated pharmacologically for spasticity. Moderate to severe spasticity was measured in 59.2% of patients according to the modified Ashworth scale and in 83.4% according to the NRS. Mean scores for the 0-100 Physical Component Summary and Mental Component Summary subscales of the SF-12 questionnaire were 31.0 (±9.3) and 45.4 (±12.0), respectively. Scores on the SF-12 correlated significantly with scores on both spasticity scales ( p ≤ 0.002) but the correlation was stronger with the NRS across all domains.
Conclusions: The results confirm an association between spasticity severity and QoL in patients with MS. The correlation between 0-10 NRS scores and QoL was stronger than that between modified Ashworth scale scores and QoL.

Responsiveness, defined as the ability to detect a meaningful change, is a core psychometric property of an instrument measuring quality of life (QoL) rarely reported in multiple sclerosis (MS) studies.
Objective: To assess the responsiveness of the Multiple Sclerosis International Quality of Life (MusiQoL) questionnaire to change in disability over 24 months, defined by change in the Expanded Disability Status Scale (EDSS) score.
Methods: Patients with MS were enrolled into a multicenter, longitudinal observational study. QoL was assessed using both the MusiQoL and the 36-Item Short-Form (SF-36) instruments at baseline and every 6 months thereafter up to month 24; neurological assessments, including EDSS score, were performed at each evaluation.
Results: The 24-month EDSS was available for 524 patients.
In the 107 worsened patients, two specific dimensions of MusiQoL, the sentimental and sexual life and the relationships with health care system dimensions, and 'physical'scores of SF-36 showed responsiveness.
Conclusions: Whereas specific dimensions of MusiQoL identified EDSS changes, the MusiQoL index did not detect disability changes in worsened MS patients in a 24-month observational study. Future responsiveness validation studies should include longer follow-up and more representative samples.
