EMG Frequency Study Synopsis


  • Telemetry EMG recordings were taken from sixteen separate muscles while subjects performed six activities: lying, throwing, lifting, jogging, stepping up on a stool, and a karate chop.
  • Comparisons were made on male and female experimental and control groups, before and after Rolfing.

Statistical findings were evaluated with reference to efficiency in specific tasks and effects on posture, flexibility and entropy.


  • Of sixteen muscles sampled fifteen showed significant changes. Better than .05 level and all above the sixty-six percent prediction of the criterion of Rolfing.
  • When experimental and control groups were compared on before and after recordings, forty three frequency parameters discriminated between groups. Of these, forty one showed distinct superior changes in the Rolfed group.

“Rolfing made consistent major improvement in efficiency of motor performance by improved organization and balance of the neuromuscular system”
