Strength training of non-hemiplegic side may improve motor recovery in diseased limb

Strength training of the non-hemiplegic side (NHS) improved the motor function like balance, mobility, and muscle strength of patients with stroke. The findings of this study was published in the Archives of Physical Medicine and Rehabilitation.

The study by Chenlan Shao recruited 139 patients with first stroke and randomly separated them into a trial group (n=69) or control group (n=70). The control group underwent usual rehabilitation training, including step training and trunk control training in standing position. The trial group underwent strength training of NHS on the basis of usual rehabilitation training. The strength training of NHS included lower limb stepping training with resisting elastic belt and upper limb pulling elastic belt training in standing position. The training for both groups was 45 min, once a day, 5 days a week for 6 weeks.

The primary outcome measures were balance evaluation done with the Berg Balance Scale (BBS); mobility assessment with the 6-minute walk test (6-MWT); activities of daily life was examined via the modified Barthel Index (MBI); muscle strengths of the biceps brachii, iliopsoas, and quadriceps were measured via the isokinetic muscle strength testing system. All assessments were performed at baseline (T0) and after the intervention (T1).

Also, the trial group performed better than control group in BBS scores (adjusted mean difference: 6.83; 95% confidence interval [CI]: 4.71-8.94) and 6-MWT (adjusted mean difference: 50.32; 95% CI: 40.58-60.05) after intervention.

In terms of muscle strength of the hemiplegic side, the trial group displayed greater gains in biceps brachii, iliopsoas, and quadriceps than control group after intervention.

In conclusion, the study found that strength training of the NHS can promote recovery of balance, mobility, and muscle strength of the paretic side of patients with stroke. The study suggests that NHS strength training may be a valuable addition to usual rehabilitation training for patients with stroke.
