Abstract

ABSTRACTOJECTIVE: To determine whether a passive stretch using Muscle Energy Technique or an active functional technique using the squat action (dynamic) improves the flexibility of the soleus muscle creating a decreased knee angle in squatting.
METHOD: 18 individuals participated in the study. The subjects were split randomly into two groups undertaking the following protocols:
Squat: Squat and measure the knee angle, squat for 15 s, rest for 1min., squat and measure the knee angle. To be applied twice a week.
Muscle Energy Technique: Squat and measure the knee angle, apply a muscle energy technique to the soleus, squat and measure the knee angle. To be applied twice a week.
Squatting for both groups was done against a fitball. Application of techniques was administered over four-week period, followed by a five-week rest period. A single re-test of two measurements was then taken for both groups. A universal goniometer was used to record measurements taken.
RESULTS: Mean difference over one treatment for four weeks:
Muscle Energy Technique = 8.1º ± 2.68; Squat = 9.3º ± 5.47
Difference between interventions over one treatment: non-significant P> = 0.591
Group interventions displayed significant changes in decrease in knee angle over the four-week treatment (T1- T16) period for both applications:
Muscle Energy Technique = P < 0.002; Squat = P < 0.015
Significant changes were displayed over the rest period of five weeks to the pre-test measurement (T17):
Muscle Energy Technique = P < 0.001; Squat = P < 0.010
Significant changes were displayed over the rest period of five weeks to the post-test measurement (T18):
Muscle Energy Technique = P < 0.002; Squat = P < 0.008
Non-significant changes were made from the end of the four-week treatment period (T16) over the rest period of five weeks to the pre-test (T17):
Muscle Energy Technique = P < 0.80; Squat = P < 0.28
Significant changes were made from the end of the four-week treatment period (T16) over the rest period of five weeks to the post-test (T18) for the M.E.T group, while the Squat group had a non-significant change:
Muscle Energy Technique = P < 0.01; Squat = P > 0.14
CONCLUSION: The results displayed that, in terms of short-term improvements in flexibility of the soleus and range of motion of the knee, appropriately chosen functional/dynamic techniques can be just as effective as Muscle Energy techniques. Treatment carryover over five-weeks of the squat technique was non-significant.
