Core Stability Exercises Yield Multiple Benefits for Patients with Chronic Stroke - Randomized Controlled Trial.

OBJECTIVE This study examines the effect of core stability exercises on trunk control, core muscle strength, standing weight-bearing symmetry and balance confidence of people with chronic stroke. DESIGN This was an assessor-blinded randomized controlled trial involving 84 ambulatory patients with middle cerebral artery stroke, randomly assigned to three training groups. Two experimental groups practiced core stability exercises either on stable or unstable support surfaces. In contrast, the control group received standard physiotherapy. All the participants an hour-long training session a day, thrice a week over a six-week duration, and followed-up after 12 months. Trunk Impairment Scale, core muscle strength, weight-bearing asymmetry in standing and Activities-specific Balance Confidence scale were the outcome measures. RESULTS Compared to the control group, the two experimental groups demonstrated a significant improvement on all the outcome measures from baseline to post-training and from baseline to 12-month follow-up (P 0.05). CONCLUSION Core stability exercises on stable and unstable support surfaces are equally beneficial in improving trunk control, core muscle strength, standing weight-bearing symmetry and balance confidence of ambulatory patients with chronic stroke than the standard physiotherapy.
