Published in: NeuroRehabilitation

For stroke patients, regaining upper extremity function and independence in daily activities is crucial. This inspiring study investigates the effects of Interactive Metronome (IM) training, a technology that improves coordination and precision, on upper limb function, Activities of Daily Living (ADLs), and quality of life in individuals recovering from stroke.

Thirty stroke patients, all at least six months post-stroke and verified for homogeneity, were equally divided into an experimental group and a control group. The experimental group underwent IM training three times per week for 12 sessions, while the control group performed bilateral arm self-exercises for the same period.

The results were promising: the IM-trained stroke patients showed marked improvements in finger control and overall motor function compared to the control group (p<0.05). The IM group also displayed significant progress in self-care ADLs (p<0.05), including feeding, toileting, dressing, and transfers, with the most significant improvement seen in dressing.

Furthermore, Quality of Life measures showed increased performance and satisfaction in the IM group, particularly in the Self-Help domain, echoing the outcomes of previous IM research on stroke patients with hemiplegia.

This study emphasizes the potential benefits of IM training in improving upper limb function, ADLs, and quality of life in stroke rehabilitation. It holds promise for clinicians, like occupational therapists and speech-language pathologists, to consider IM as a therapeutic intervention in their practice to enhance the rehabilitation outcomes of stroke patients.

Abridged Summary & Results of Study

Effects of Interactive Metronome training on upper extremity function, ADL and QOL in stroke patients

AUTHORS: Ga-Hui Yu, Jae-Shin Lee, Su-Kyoung Kim, & Tae-Hyun Cha


Stroke patients who received Interactive Metronome (IM) training demonstrated greater improvement in finger control, ability to perform self-care ADLs & overall motor function compared to a control group. Significant ADL improvements were noted in the areas of feeding, toileting, dressing & transfers with most notable difference in dressing. Quality of life measures indicated greater performance & satisfaction for those that received IM training, particularly in the domain of Self-Help, which is in line with the outcome of previous IM research on stroke patients with hemiplegia.


  • n=30 adults, 6 months post-CVA were randomly assigned to:
  • experimental group: 15 patients completed IM training 3x/week for 12 sessions
  • control group: 15 patients completed bilateral arm self-exercises for the same period of time
