Immediate Effects of Mental Singing While Walking on Gait Disturbance in Hemiplegic Stroke Patients: A Feasibility Study.

Objective: To investigate the immediate therapeutic effects of mental singing while walking intervention on gait disturbances in hemiplegic stroke patients.

Methods: Eligible, post-stroke, hemiplegic patients were prospectively enrolled in this study. The inclusion criteria were a diagnosis of hemiplegia due to stroke, and ability to walk more than 10 m with or without gait aids. Each patient underwent structured music therapy sessions comprising 7 consecutive tasks, and were trained to sing in their mind (mental singing) while walking. Before, and after training sessions, gait ability was assessed using the 10-Meter Walk Test (10MWT), the Timed Up and Go test (TUG), gait velocity, cadence and stride length.

Results: Twenty patients were enrolled in the interventions. Following the mental singing while walking intervention, significant improvement was observed in the 10MWT (13.16±7.61 to 12.27±7.58; p=0.002) and the TUG test (19.36±15.37 to 18.42±16.43; p=0.006). Significant improvement was also seen in gait cadence (90.36±29.11 to 95.36±30.2; p<0.001), stride length (90.99±33.4 to 98.17±35.33; p<0.001) and velocity (0.66±0.45 to 0.71±0.47; p<0.002).

Conclusions: These results indicate the possible effects of mental singing while walking on gait in patients diagnosed with hemiplegic stroke.
