Background: Multiple sclerosis (MS) is a chronic disabling disease of the central nervous system which impairs muscular function and limits individuals' ability to carry out everyday activities requiring mobility. People with MS frequently exhibit mobility problems (i.e., slower walking speed, shorter strides). General exercise training (e.g., resistance, aerobic) provides modest physiological and walking mobility benefits. However, reviewers suggest tailoring of interventions to address mobility specifically. We conducted a Phase IIa pre-post intervention development study (ORBIT intervention development model) of a mobility exercise plus cognitive behavioral counselling intervention to improve function and social cognitions known to encourage exercise.
Methods: The intervention was conducted twice per week for 8 weeks followed by 1 month of self-managed mobility exercise. Participants (N = 29, mean age = 52.24 ± 11.36 years, mean time since MS diagnosis = 11+ years) were assessed at baseline and post follow-up on mobility function, social cognitions, and intervention fidelity indicators.
Results: Results indicated significant improvements in a number of valid measures of mobility function (e.g., 400m walk), self-regulatory efficacy for mobility exercise and symptom control, and fidelity measures with small to medium effect sizes.
Conclusions: Positive findings suggest that the intervention appears to merit testing as a randomized pilot study following the ORBIT model.
