Music Upper Limb Therapy-Integrated Provides a Feasible Enriched Environment and Reduces Post-stroke Depression: A Pilot Randomized Controlled Trial.

OBJECTIVE

This study's aims were to refine Music Upper Limb Therapy-Integrated (MULT-I) to create a feasible enriched environment for stroke rehabilitation and compare its biologic and behavioral effects with that of a home exercise program (HEP).

DESIGN

This was a randomized mixed-methods study of 30 adults with post-stroke hemiparesis. Serum brain-derived neurotrophic factor and oxytocin levels measured biologic effects, and upper limb function, disability, quality of life, and emotional well-being were assessed as behavioral outcomes. Participant experiences were explored using semistructured interviews.

RESULTS

MULT-I participants showed reduced depression from preintervention to postintervention as compared with HEP participants. Brain-derived neurotrophic factor levels significantly increased for MULT-I participants but decreased for HEP participants, with a significant difference between groups after excluding those with post-stroke depression. MULT-I participants additionally improved quality of life and self-perceived physical strength, mobility, activity, participation, and recovery from preintervention to postintervention. HEP participants improved upper limb function. Qualitatively, MULT-I provided psychosocial support and enjoyment, whereas HEP supported self-management of rehabilitation.

CONCLUSIONS

Implementation of a music-enriched environment is feasible, reduces post-stroke depression, and may enhance the neural environment for recovery via increases in brain-derived neurotrophic factor levels. Self-management of rehabilitation through an HEP may further improve upper limb function.
