An Investigation of Interactive Metronome and Modified Constraint-Induced Movement Therapy as a Possible Combined Rehabilitation for Stroke Survivors

Abstract

The purpose of this single case study was to investigate the effects of a combined intervention with Interactive Metronome (IM) and modified Constraint Induced Movement Therapy (mCIMT) on motor recovery in a stroke survivor. A combined intervention protocol was established with 50 minutes of traditional IM, 50 minutes of IM with a constraint, and 50 minutes of mCIMT. Daily progress and change was measured using the Nine-Hole Peg Test (9-HPT) and IM Short Form Test (SFT) prior to each session. Change between pre-test, mid-test, and post-test was measured with the 9-HPT, IM SFT, IM Long Form Assessment, and the Wolf Motor Function Test. Additionally, the Canadian Occupational Performance Measure was conducted before and after the study to assess the participant's perception of change in occupational performance. Data analysis found the results to have clinical and statistical significance between the participant's pre-test, mid-test, and post-test scores as well as the change in daily progress. These results indicate that a combined IM and mCIMT intervention for stroke motor recovery can increase motor movements. Further research is warranted to determine generalizability of this intervention given the limitations of a single case study.
