Published Study Results: IM for Rehab of Blast Related TBI

Dr. Nelson will present the findings of a recently completed randomized controlled, trial of Interactive Metronome (IM) therapy in the treatment of persisting cognitive symptoms following blast-related traumatic brain injury in a sample of active duty Soldiers. Soldiers were randomly assigned to receive either standard rehabilitation care, or standard care plus Interactive Metronome therapy.

Initial findings show that IM therapy significantly improved Attention, Immediate Memory, and Delayed Memory functioning. Indicators of neuroplastic change suggest that brain changes due to IM therapy account for large portions of the variance in neuropsychological test performance. Six month follow-up data are currently being collected. Preliminary results were published in the journal: Neuropsychology in 2013 with additional publications pending completion of the study and further analysis of electro-cortical and follow-up data.

Published Research Studies

Effects of Neurocognitive Temporal Training on Weapon Firing Performance

Leah R. Enders, Gary L. Boykin, and Valerie J. Rice


Active duty U.S. Army service members with prior marksmanship experience that received Interactive Metronome (IM) training demonstrated significantly reduced variability and improved precision when firing at a 175m target when compared to matched controls. This study revealed a promising neurocognitive temporal training effect on weapon firing precision.


  • Subjects were randomly assigned to:
    • Experimental group: n=18 (mean age = 31) active duty service members received 12 sessions of IM training
    • Control group: n=23 (mean age = 26) active duty service members that did not receive IM training
  • Outcome measures:
    • Weapon firing using a weapon firing simulator, the Engagement Skills Trainer 2000 using a mock M16A4 without laser assist to hit random order stationary and moving targets up to 300m distance.
      • TPL: total path length (a precision measure to capture shot-to-shot realignment, a critical component of repeated firing)
    • Accuracy is a measure of how close the shot came to hitting the COM (center of mass (a 4-cm zone in the center of the targets, also known as the lethal zone)
      • Total Hit Point score captured how well participants fired a shot in the designated lethal (COM) versus nonlethal zones.
      • Shot Group Distance from Center of Mass (DCMSG): the distance between the center of the shot group and the COM, representing the average error of a participant’s shot group
      • Individual Shot Distance from Center of Mass (DCMS): the average distance between the individual shots of the shot group and the COM, representing the individual error of each shot fired
    • Precision is a measure of shot reproducibility or variability and is defined as how consistent or tight the shot group was in terms of location on the target (as an example, previous IM studies on the sport of golf have shown increased precision and decreased variability of the golf shot following IM training with golfers consistently hitting the ball closer to the pin)
      • Mean Radius (MR): overall mean distance of all shots and the center of the shot group or radial spread of the shot group (least sensitive to abberant shots)
      • Height and width (H+W): sum of the horizontal range and vertical range of the shots on the target, indicating the horizontal and vertical spread of shot group
      • Total Path Length (TPL): sum of distances between each consecutive shot location (most sensitive to abberant shots, measures variability or the ability to hit the same location on a shot-to-shot basis)

Effects of Interactive Metronome® Therapy on Cognitive Functioning After Blast-Related Brain Injury: A Randomized Controlled Pilot Trial

Lonnie A. Nelson, Margaret MacDonald, Christina Stall & Renee Pazdan
Published in Neuropsychology


Active duty soldiers with mild-moderate traumatic brain injury (TBI) who received Interactive Metronome (IM) training in addition to standard rehabilitation care (SRC), demonstrated statistically significant improvements on 21 out of 26 neuropsychological batteries in the areas of attention, inhibition, processing speed, motor speed, immediate memory, and delayed memory compared to soldiers that only received SRC.


  • n=46 active duty soldiers, 21–49 years of age, approximately 29 months post TBI were randomly assigned to:
    • Experimental group: 18 received SRC plus 15 1-hr IM training sessions
    • Control group: 18 received SRC only
  • Soldiers all had blast-related mild-to-moderate TBI and displayed persistent, chronic cognitive deficits
  • To control for bias, investigators completing pre-post assessments were blinded to the participants randomized group assignment
  • Assessments included: Wechsler Test of Adult Reading (WTAR), Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Integrated Visual and Auditory Continuous Performance Test (IVA-CPT), Delis–Kaplan Executive Functioning System (D-KEFS) Trail Making and Color–Word Interference subtests, Test of Memory
    Malingering (TOMM), Grip Strength and Grooved Pegboard, Wechsler Adult Intelligence Scale–Fourth Edition (WAIS-IV), including Digit Span, Letter–Number Sequencing, Digit–Symbol Coding, and Symbol Search subtests & Rivermead Post Concussion Symptoms Questionnaire, Mayo–Portland Adaptability Inventory–4, Satisfaction With Life
    Scale, & The Alcohol Use Disorders Identification Test (AUDIT-C).
