Purpose: The application of tape to modulation of pain and muscular excitability has become common clinical practice among musculoskeletal physical therapy. However, the techniques of the tape application has been relied on empirical evidence in preference to the neurophysiological evidence. Thus, the mechanism of taping has to be elucidated further. The aim of this study was to determine whether elastic and non-elastic taping across a muscle does indeed change -motor neuron excitability.
Methods: The study was performed on 10 neurologically healthy adults. Two different types of tape were applied to skin overlying gastrocnemius. The elastic tape stretched up to 120% of its original length but non-elastic tape didn’t stretched up of its original length. The tape applied across the direction on thickest part of the gastrocnemius. The -motor neuron excitability of the gastrocnemius was assessed using the gastrocnemius H-reflex. The amplitude of the M-wave and H-reflex were measured across three conditions: before tape application, with tape and with the tape removed.
Results: No significant changes of the excitability of the -motor neuron were obtained across three condition, either in the elastic and non-elastic tape.
Conclusion: From the results, I could come to the conclusion that further clinical work will be required.
