What is IM?

The Interactive Metronome® (IM) is a brain-based rehabilitation assessment and training program developed to directly improve the processing abilities that affect attention, motor planning, and sequencing. This, in turn, strengthens motor skills, including mobility and gross motor function, and many fundamental cognitive capacities such as planning, organizing, and language.

How does IM work?

The IM program provides a structured, goal-oriented training process that challenges the patient to precisely match a computer generated beat. Participants are instructed to synchronize various hand and foot exercises to a reference tone heard through headphones. The patient attempts to match the rhythmic beat with repetitive motor actions such as tapping his/her toes on a floor sensor mat or hand clapping while wearing an IM glove with palm trigger.

A patented audio or audio-visual guidance system provides immediate feedback. The difference between the patient's performance and the computer-generated beat is measured in milliseconds. The score provided indicates timing accuracy.


Motor planning and sequencing problems have been linked to a variety of developmental, behavioral, and learning challenges. More than a decade of clinical research on IM® demonstrates that gains in motor planning, rhythmicity, timing and sequencing lead to improvements in:

  • Attention and Concentration

  • Language Processing

  • Behavior (Aggression and Implusivity)

  • Motor Control and Coordination

  • Academic Performance

Clinical Results

ADHD Study

A double-blind, placebo-controlled study of 9 to 12-year-old males diagnosed with ADHD found those who completed the IM program showed significant patterns of improvement in attention, coordination, control of aggression/impulsivity, reading and language processing. This study was published in the American Journal of Occupational Therapy, March 2001.

Timing in Child Development Study

A correlation study of 585 children in a public school district found significant correlations between IM score and academic performance in reading, mathematics, language, science, social studies, and study skills. This suggests that timing and rhythmicity play a foundational role in the cognitive processes underlying performance in these academic areas. The results were published by the High/Scope Foundation, a prestigious, non-profit educational research institution.
