There are 9 clinical trials
Over half of persons with multiple sclerosis (MS) report falling over a 6-month period and a majority of those who fall require medical attention for injuries. Importantly, balance dysfunction, muscle weakness, and spasticity are modifiable risk factors for falls among community-dwelling older adults and likely persons with MS. Indeed, there is evidence that these physiological risk factors can be minimized with exercise training in persons with MS and this might translate into a decrease in fall risk as documented in community-dwelling older adults. The investigation will examine the effectiveness of a home-based exercise program that is designed to reduce fall risk by targeting specific fall risk factors including balance dysfunction and two of its latent causes, muscle weakness and spasticity in persons with multiple sclerosis. It is predicted that persons who receive home-based exercise program will have a reduction in fall risk.
Mobility will be quantified with performance on timed 25 foot walk (T25W), timed up and go (TUG), Six spot step test, 6 minute walk and the MS walking scale-12.. Balance. --- T25W ---
Description: Physiological fall risk will be determined by the physiological profile assessment which assesses physiological function related to fall risk by combining measures of vision, proprioception, lower-limb strength, postural sway, and cognitive function.

Measure: Spasticity Time: 3 MonthsFalls are a serious health concern for persons with multiple sclerosis (MS). Over 50% of persons with MS suffer a fall over a 6-month periodwith the majority of falls resulting in medical attention for injuries (i.e., lacerations, bone fractures, & head injuries). The effects of a fall are often compounded as it can lead to activity curtailment, physiological deconditioning, and institutionalization. Despite the importance of falls in persons with MS, the appropriate prevention strategies (i.e. rehabilitation approaches) are not clear. The purpose of this investigation is to determine whether exercise based or educational based interventions are more suited for fall prevention in older adults with MS.

Description: The VAS for pain is a subjective measure and it consists of a 100 millimeter (mm) line with two end points representing 'no pain' to 'pain as bad as it could be'.

The distance along the line from the 'no pain' marker is then measured with a ruler giving a pain score out of 10.

Measure: Change from Baseline Over Time in Expanded Disability Status Scale (EDSS) Score Time: Baseline and every 24 weeks thereafter until 12 weeks after last dose of satralizumab (up to approximately 7.25 years)The purpose of this clinical trial is to determine if Domperidone in a dose of 40 mg daily can prevent worsening of walking ability in people secondary progressive MS. The number of participants in this study will be 62. A maximum of 75 people with secondary progressive MS will be included. Each patient will be followed for 12 months from inclusion. Domperidone is a medication which has been shown to increase levels of the hormone prolactin. The best understood function of prolactin is the stimulation of milk production in women after delivery. However, the increase in prolactin levels seen in patients treated with standard doses of Domperidone (in doses of up to 80mg per day) usually does not lead to clinical symptoms. Prolactin has been shown to improve myelin repair in mice. Domperidone therefore may also improve myelin repair in people with MS. Domperidone is currently approved in Canada to treat slow moving bowels and nausea, for instance in patients with Parkinson's Disease or Diabetes Mellitus, where too slowly moving bowels can cause constipation. Domperidone is available as a tablet that is usually taken four times per day. Doses up to 80mg per day may be used but we estimate that a dose of only 40mg daily will be needed to stimulate myelin repair. Domperidone is usually well tolerated.
