Brief Summary

This study investigated the immediate effects of two manual therapy approaches, myofascial release and the fascial distortion model, applied to the calf and plantar fascia in healthy adults. Participants were randomly assigned to one of the two intervention groups. Flexibility, balance, and postural control were assessed before and after the intervention to examine potential remote effects along the superficial back line. The purpose of this study was to compare the short-term functional effects of these two manual therapy techniques.

Outcome Measures

Primary Outcomes (1)

• Weight-Bearing Lunge Test (WBLT)

  The Weight-Bearing Lunge Test was used to assess ankle dorsiflexion range of motion by measuring the maximum distance (cm) from the great toe to the wall while maintaining heel contact.

  Immediately before and immediately after the intervention

Secondary Outcomes (5)

• Straight Leg Raise Test (SLR)

  Immediately before and immediately after the intervention

• Functional Reach Test (FRT)

  Immediately before and immediately after the intervention

• Single-Leg Hop for Distance Test (SLHD)

  Immediately before and immediately after the intervention

• Bunkie Test (BT)

  Immediately before and immediately after the intervention

• Finger-to-Floor Distance Test (FFD)

  Immediately before and immediately after the intervention
