Fine-Tuning Motor Skills: How Interactive Metronome® Boosts Bilateral Coordination in Hemiplegic Cerebral Palsy Children

Published in Journal of Korean Society of Occupational Therapy


Pediatric, Motor Skills

The aim of this study was to assess the impact of Interactive Metronome (IM) training on bilateral coordination, balance, and upper extremity function in a child with hemiplegic cerebral palsy. The research was structured as a single-subject experimental study using an ABA design.

The child participant was observed twice a week for 10 weeks, making a total of 20 sessions. In the first phase, the child’s bilateral coordination was evaluated without intervention across four sessions.

The second phase consisted of 12 sessions, during which the child underwent 40-minute IM training twice a week, with bilateral coordination measured after each training. The third phase mirrored the first, collecting data using the same non-intervention procedure.

The child’s balance was evaluated before and after treatment, and hand function was assessed pre-, interim-, and post-treatment.

Following IM training, the participant exhibited improved bilateral coordination and balance, with the changes deemed significant.

Hand function also increased, although the improvement wasn’t statistically significant.

The results of this study suggest that IM training can have a beneficial effect on bilateral coordination and balance in children with hemiplegic cerebral palsy.

The Effects of Interactive Metronome® on Bilateral Coordination, Balance, and Upper Extremity Function for Children with Hemiplegic Cerebral Palsy: Single-Subject Research

AUTHORS: Ji-Hye Jung & Su-Kyoung Kim


YEAR: 2012

An individual with hemiplegic cerebral palsy (CP) demonstrated significant improvement in bilateral coordination and balance following Interactive Metronome (IM) training.


  • n=1 single-subject experimental research using an ABA design
    • Evaluated bilateral coordination without intervention in the baseline phase (A) for four sessions
    • IM training provided for 40 minutes 2x/week for 10 weeks, with a total of 20 sessions, and bilateral coordination was measured after each training
    • During the second baseline phase, data were collected using the same procedure as the first baseline phase, with balance assessed before and after IM training
