The impact of cycling exercise on motor and functional recovery of patients in acute and subacute stroke phase

Introduction/Objective. Neurological impairment and immobility in stroke patients can lead to numerous complications. This study aimed to evaluate the effect of cycling exercises with visual feedback combined with conventional rehabilitation on neurological and motor recovery, balance, walking speed and endurance, and activities of daily living (ADL) in patients after acute and subacute stroke. Methods. A randomized prospective controlled trial was applied to this research. One hundred and twenty-seven hemiplegic stroke patients who received in-hospital rehabilitation were randomly assigned into two groups. Both groups received conventional rehabilitation treatment. The experimental group had an extra 30 minutes of cycling exercises for the upper and lower extremities on a stationary ergocycle MOTOmed muvi. Both groups? neurological status, upper and lower limb function, independence in ADL, balance, walking speed, and endurance were observed before and after the rehabilitation treatment. Outcome measures used were the National Institute of Health Stroke Scale (NIHSS), the modified Ashworth scale (MAS), the Brunnstrom Motor Evaluation Scale (BMES), upper and lower Fugl-Meyer assessment (FMA), the Barthel index (BI), the Berg Balance Scale (BBS), the six-minute walk test (6MWT) and the Timed Up and Go test (TUG). Results. The neurological recovery on the NIHSS scale, spasticity of the knee extensor measured by the MAS, the BMES and FMA-LE subscale for the affected leg, and the 6MWT presented more significant improvement in the experimental group than in the control group after the treatment (p < 0.05 for all three analyses). Conclusion. Cycling exercises with visual feedback combined with conventional rehabilitation could promote neurological recovery and improve the motor function of the affected leg and walking speed in patients recuperating after acute and subacute stroke.
