Effect of Dynamic Neuromuscular Stabilization on Balance, Trunk Function, Falling, and Spasticity in People With Multiple Sclerosis: A Randomized Controlled Trial.

OBJECTIVE

To compare the effects of core stabilization (CS) and dynamic neuromuscular stabilization (DNS) on balance, trunk function, mobility, falling, and spasticity, in people with multiple sclerosis (PWMS).

DESIGN

Two-group randomized controlled trial.

SETTING

General community and referral center.

PARTICIPANTS

A total of 64 PWMS, between 30 and 50 years old, and an expanded disability status scale between 2 and 5, participated in this study (N=64).

INTERVENTIONS

Participants were randomly assigned to CS (n=32) and DNS (n=32) groups. Both groups received a total of 15 sessions of CS or DNS exercises, 60 minutes per session, 3 times a week during the 5 weeks.

OUTCOME MEASURES

Balance function was measured as the primary outcome measure. Trunk function, postural stability, falling rate, fear of falling, falling index, mobility, and spasticity were measured as secondary outcomes.

RESULTS

DNS group had significant improvement in Berg balance scale, trunk impairment scale, postural stability, activities-specific balance confidence, reduced falling rate, the timed Up and Go (TUG), multiple sclerosis walking scale-12, and multiple sclerosis spasticity scale in PWMS compared with the CS group, (P<.0001) after 5 weeks of intervention and 17 weeks of follow-up. Except for the modified Ashworth scale (MAS), significant improvements were seen in all outcome measures in both groups after 5 weeks of intervention.

CONCLUSION

This is the first clinical evidence to support the importance of DNS exercise in improving balance, trunk function, and fall prevention in PWMS. This study provides clinical evidence that DNS may be more effective for PWMS than CS.
