Immediate Effect on Pain Thresholds Using Active Release Technique on Adductor Strains: Pilot Study

J Bodyw Mov Ther. 2011 Jan;15(1):57-62. doi: 10.1016/j.jbmt.2010.04.004. Epub 2010 May 6.


Background: Pain pressure thresholds (PPT) have not been investigated when Active Release Techniques (ART(®)) is directed at treating soft tissue injuries.

Aim: To investigate the immediate effects of ART(®) employed in the management of adductor muscle strains to modulate pain threshold.

Methods: Patients were administered ART(®) commensurate with the extent and nature of their adductor muscle injury. The outcome measureused was PPT over the adductor muscle strain which was assessed pre-intervention and 2min post-intervention.

Results: Within group effect sizes were calculated using a paired samples t-test to assess clinical effect. The mean pre-intervention and 2min post-intervention PPT values were 4.2±0.83 and 5.3±0.99 significantly different (p<0.001).

Conclusion: The application of ART(®) to treat groin strains may be of benefit in increasing pain thresholds amongst ice-hockey players. Future research requires sufficient sample sizing, a control group, and correlations with objective outcome measures (VAS and range of motion) to validate the therapeutic effect of ART(®).
