FARMS-2: Fall Risk Reduction in Multiple Sclerosis: Exercise Versus Behavior
Study Details
Study Description
Brief Summary
Falls 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.

Detailed Description
Falls 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.
It is well known that causes of falls are multifactorial with over 400 risk factors identified. However, it is believed that these factors can be divided into two main classes: intrinsic (e.g. physiological factors) and extrinsic factors. For instance balance dysfunction, spasticity and muscle weakness are physiological risk factors for falls in MS . Behavioral fall risk factors in MS include choosing appropriate footwear, lighting and utilizing appropriate assistive device. There is evidence that both types of risk factors can be minimized with appropriately designed interventions in persons with MS and have been shown to reduce fall risk and incidence in other clinical populations. This has led to calls for the combination of exercise training program that targets specific, modifiable physiological risk factors and educational interventions targeting modifiable behavioral risk factors in persons with MS. However, there is minimal evidence that these interventions in isolation or combination actually reduce fall incidence or risk in persons with MS. This proposal seeks to determine the effectiveness of a combined exercise and educational rehabilitation strategy to prevent falls in persons with MS.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Home-based Exercise Participants will be taught a series of exercises targeting balance and lower limb strength in four instructional sessions. They will be asked to complete exercises 3 times a week for 12 weeks. Exercise compliance will be recorded with a diary. |
Behavioral: Home-based exercise
exercise to look at balance and lower limb strength record in diary
|
| Experimental: Education Participants will attend 4 education sessions focusing on interaction of beliefs, behaviors and symptoms on falls. They will be taught self-management principles to modify their fall risk. |
Behavioral: Education
sessions to discuss self-management ideas to modify risk of falling
|
| Experimental: Exercise plus education Participants will attend 2 instructional exercise sessions as well as 2 education sessions. Participants will be asked to complete exercises at home 3 times per week and engage in behavior to minimize fall risk. |
Behavioral: Exercise plus Education
combination of exercise sessions with education sessions to modify fall risk
|
| No Intervention: Control Participants will not receive any treatment. |
Outcome Measures
Primary Outcome Measures
- Fall incidence [3 months]
Secondary Outcome Measures
- Physiological Fall Risk [3 Months]
Physiological fall risk will be determined by the short form of the Physiological Profile Assessment (PPA)(Lord, 2003). The PPA is a standardized test battery which assesses vision (edge contrast sensitivity), lower limb proprioception, strength (knee extension), postural sway, and cognitive function (simple hand reaction time). The outcome of each test will be combined to generate an overall fall risk score
- Mobility [3 months]
Specific measures of walking speed, endurance, coordination and self-reported walking function scale will be employed to assess overall mobility of each person. Walking speed was quantified with the Timed 25-Foot Walk (T25W), walking endurance was assessed with the 6-Minute Walk (6MW), and functional mobility was quantified with the Timed Up and Go (TUG) . The Multiple Sclerosis Walking Scale-12 (MSWS-12) will be used as a self-reported measure of walking impairment.
- Balance [3 Months]
To assess balance (e.g. postural control), we conducted a clinical assessment To measure balance the Berg Balance Scale (BBS) and self-reports of balance confidence will be used. The BBS is a clinical assessment of balance. Scores on the BBS range from 0-56 with higher scores indicating greater balance. The Activities-Specific Balance Confidence (ABC) scale was used as a measure of balance confidence.
