The effects of the Interactive Metronome® as an intervention tool on decreasing levels of aggression and improving life satisfaction with mild traumatic brain injury and post- traumatic stress disorder clients: a pilot study of protocols

Abstract

The purpose of this study was to validate the protocols created for the Interactive Metronome® (IM®) and TRX® Suspension Training (TRX®) system for use with clients diagnosed with mild Traumatic Brain Injury (mTBI) and Post-Traumatic Stress Disorder (PTSD). Protocols were established matching IM® routines in conjunction with TRX® exercise routines. These were then validated on two healthy male and two healthy female participants. The data collected was collected using the IM® Long Form and Short Form Assessments, the Nine Hole Peg Test, the Canadian Occupational Performance Model and a version of the Overt Aggression Scale. Percentages of change were then compared between instruments and individuals for positive efforts gained, along with additional statistical analyses conducted. Data analysis indicated the use of the IM® in conjunction with the physical challenge of the TRX® provide a positive change maintaining or lowering aggression levels and increasing life satisfaction. The IM® protocols created, paired with the TRX®, were effective instruments used for creating a change in healthy participants. Occupational therapists will be able to benefit from the information collected and use it towards bettering the lives of those with mild TBI and PTSD. Future research with this intervention should anticipate favorable outcomes with mild TBI and PTSD cases.
