Introduction: Non-pharmacological rehabilitation of Multiple Sclerosis (MS) is an important topic. Only little is known about the effects of progressive resistance training (PoRT) versus core and stability training (CoaST).
Objective: To explore the effects of progressive resistance training (PoRT) with weight machines versus core and stability training in groups (CoaST) using the body weight compared to a waiting group. Are there differences in the outcomes of muscle performance, balance and spasticity?
Methods: A randomized controlled three-armed multi-centre trial with a 6 months study period was performed.
SUBJECTS: 70 individuals with MS (mean age 46.3 years, mean average EDSS of 3.22) were randomly allocated into three groups.
Intervention: The three strands were the PoRT, CoaST and a waiting group without exercise training. Participants trained 60 minutes per week for an intervention period of 24 weeks.
MEAN OUTCOME PARAMETERS: Muscle performance was assessed for 5 muscle groups. Balance was measured by a dynamic posturography. Spasticity was recommended by the modified Ashworth Scale (MAS).
Results: After 24 weeks both intervention groups showed significant improvements of the muscle strength. The PoRT-group improved 54.8% (p=0.001), the CoaST-group improved 43% (p=0.006) in comparison to the control-group with 4.8% (p=0.489) from baseline. Both intervention groups showed significant improvements of balance in the saggital stability (CoaST p=0.024; PoRT p=0.008). The PoRT-group could also improve their frontal postural control significantly (p=0.001). Both groups showed highest improvements within the first 12 weeks of intervention.
The spasticity could be reduced significantly in both intervention groups after 24 weeks (CoaST, p=0.001; PoRT, p=0.011).
Conclusion: Sixty minutes once a week of specific physical activities has various benefits for people with multiple sclerosis. Even an intermediate individualized training stimulus offered in group situations (PoRT) has positive effects like an advanced individualized training on weight machines (CoaST). This underlines the necessity to offer exercise groups when there are no weight machines training facilities. Physical activity is an effective non-pharmacological therapy tool. Further trials are required to investigate which effects have the highest influence on muscle performance, balance and spasticity.
