Treadmill Training in Chronic MS: Efficacy and Cost-effectiveness
Treadmill Training in Chronic MS: Efficacy and Cost-Effectiveness
Descripción general del estudio
Descripción detallada
Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system, which can cause episodic, static or progressive disability. Frequently, MS causes weakness and spasticity of the legs leading to gait abnormalities and immobility. Rehabilitation has been widely used in MS but has been the subject of limited investigation. In particular, traditional thinking in MS providers was that aerobic exercise could cause worsening of symptoms in some patients and should generally be avoided. Recent studies suggest that both aerobic exercise is tolerated by most patients and improves fitness. In a recent study however, training with bicycle ergometers did not translate into improved biomechanics of gait. This suggests that aerobic training may need to be coupled to task specific training to produce improved gait. With recent changes in medical care focusing on cost containment, studies supporting the effectiveness and cost-effectiveness of rehabilitation interventions are needed.
Studies from the stroke literature suggest that task specific training may be useful in promoting motor reorganization in the cortex, reversing muscle wasting and improving cardiovascular de-conditioning. In particular, we have examined the use of treadmill training in patients with chronic hemiparesis due to stroke and have found that a course of training can improve walking ability, can cause an increase in motor representation of the effected limb as measured by fMRI, can increase muscle mass as measured by thigh CT and muscle biopsy, and can improve cardiovascular fitness as measured by treadmill stress testing.
Proposed is a pilot study testing a program of treadmill training in patients with chronic leg weakness and spasticity due to MS causing chronic gait problems. The primary objectives of this pilot study are to demonstrate the safety and tolerability of the treadmill training program in MS patients and to obtain preliminary data on outcomes to use to determine the sample size for a larger trial designed to document efficacy and cost-effectiveness. Forty MS patients with impaired ambulation will be randomized to a 3 month program of treadmill training or a 3 month education and counseling program with attention equal to the treadmill trained group. Both groups will be followed for a total of 6 months. The treadmill training will be carried out in the Senior Exercise Research Center at the Baltimore VAMC. Outcome measures will include measures of leg strength and spasticity, disability (EDSS), walking ability, cardiovascular fitness, Quality of Life, depression, and healthcare costs and utilization (compared to the year prior to enrollment). The results of this pilot study will be used to design and gain support for a study sized to measure efficacy and cost effectiveness.
