Enriched Music-Supported Therapy to Restore Motor Deficits After Stroke

Playing and Singing for the Recovering Brain: Efficacy of Enriched Social-Motivational Musical Interventions in Stroke Rehabilitation

Music-Supported Therapy (MST) is a rehabilitation technique to improve the upper extremity motor function of stroke patients through playing musical instruments. A modified version of the MST protocol has been created (hereafter, referred as enriched MST, eMST) to include (i) a home-based self-training program using an app for electronic tablets and (ii) weekly group sessions of musical playing strengthening the motivational and emotional components of music playing. A randomised controlled trial will be conducted to test the effectiveness of this enriched MST (eMST) protocol in improving motor functions, cognition, emotional well-being and quality of life when compared to a program of home-based exercises utilizing the Graded Repetitive Arm Supplementary Program (GRASP). Sixty stroke patients will be recruited and randomly allocated to an eMST group (n=30) or a control GRASP intervention group (n=30). Patients will be evaluated before and after a 10-week intervention, as well as at 3-month follow-up. The primary outcome of the study is the functionality of the paretic upper limb measured with the Action Research Arm Test. Secondary outcomes include other motor and cognitive functions, emotional well-being and quality of life measures as well as self-regulation and self-efficacy outcomes. We hypothesize that patients treated with eMST will show larger improvements in their motor and cognitive functions, emotional well-being and quality of life than patients treated with a home-based GRASP intervention.

Inclusion criteria:

• Presence of mild-to-moderate paresis of the upper extremity after a stroke (having a score between 1 and 4 in the Medical Research Council Scale for Muscle Strength at the distal muscles of the upper extremity);
• More than 6 months post-stroke;
• Completion of formal rehabilitation programs.

Exclusion criteria:

• Major language or cognitive deficits affecting comprehension (Mini-Mental State Examination < 24);
• Neurological or psychiatric co-morbidity;
• Other musculoskeletal condition affecting upper extremity motor function (e.g. fracture or arthritis).
