Summary

This pilot study aimed to compare the immediate effects of two manual therapy techniques, strain counterstrain (SCS) and the fascial distortion model (FDM), on pain-related outcomes and neuromuscular function in individuals with latent myofascial trigger points of the upper trapezius muscle. Twenty healthy adults with identified latent trigger points were randomly assigned to receive a single session of either SCS or FDM. Cervical range of motion, proprioception, pressure pain threshold, and cervical muscle strength were assessed before and immediately after the intervention. This study was conducted to obtain preliminary data regarding the short-term effects of two manual therapy approaches with contrasting stimulation characteristics.

Conditions

  • Latent Myofascial Trigger Points
  • Upper Trapezius Muscle

Interventions

OTHER

Strain Counterstrain

Strain counterstrain is an indirect manual therapy technique in which the body is passively positioned in a pain-free posture to reduce nociceptive input and muscle tension. In this study, a single session of strain counterstrain was applied to latent myofascial trigger points of the upper trapezius muscle.

OTHER

Fascial Distortion Model

The fascial distortion model is a direct manual therapy approach that applies localized, high-intensity pressure to specific fascial distortions identified through patient body language and palpation. In this study, a single session of fascial distortion model intervention was applied to latent myofascial trigger points of the upper trapezius muscle.
