Efek Akut Passive dan Active Myofascial Release terhadap Panjang dan Elektromyografi pada Tightness Otot Rektus Femoris
Daftar Isi:
- Background: Myofascial release (MFR) is a form of manual therapy that involves the application of a low load, long duration stretch to the myofascial complex, intended to restore optimal length, decrease pain, and improve function. Currently there is no clear evidence that shows passive and active MFR effects on muscullar disorders. Objective: The aim of this study is to know whether passive ande active MFR have acute effects on rectus femoris muscle tightness especially on muscle length and electromyography. Methods: An experimental study with pre and post test on fifteen patients were assigned randomly into three group. The first group underwent 135s passive MFR, the second group underwent 135s active MFR, and the third group underwent 135s placebo treatment. Data was collected and analyzed with wilcoxon and mann-whitney test. Results: Results revealed that passive MFR effect on muscle length (p = 0,042), passive MFR effect on electromyography (p = 0,225), active MFR on muscle length (p = 0,042), active MFR on electromyography (p = 0,465), placebo on muscle length (p = 1), placebo on electromyography (p = 0,892). The difference between passive and active MFR efficacy on muscle length (p = 0,916). Conclusion: There is an increase in muscle length on group 1 and group 2 with no different efficacy. There is no effect of 135s passive and active MFR on rectus femoris electromyography. There is no effect of placebo treatment on both muscle length and electromyography.
