Abstract

This is a quasi-experimental study that utilized pretest-posttest two (2) group design that determined the effectiveness of auto relax EMG biofeedback in treating patients with myofascial pain syndrome (MPS) as to pain and disability status. The study population was chosen using non-probability purposive sampling based on the inclusion and exclusion criteria. Fifteen (15) subjects were included in the study and were divided into two (2) groups. Five (5) subjects were allocated to control group while 10 subjects to experimental group. Indexes for pain and disability status were measured through visual analogue scale (VAS) and neck disability index (NDI) respectively and pertinent demographic data was recorded by the researchers before and after the treatment until the end of 12 treatment sessions of the study. Experimental group was treated with auto-relax EMG biofeedback for 20 minutes every session. After 12 treatment sessions, experimental group showed a statistically significant result as to decreasing pain and improving the disability status. When the two groups were statistically analyzed using independent t-test at 0.05 level of significance, results showed that the difference between control and experimental group was not significant based on the results in decreasing pain and improving disability status. The researchers conclude that there was no sufficient evidence to prove that EMG biofeedback was more effective than the other. Statistical findings showed that both groups were effective in decreasing pain and improving disability status of 15 MPS patients. However, there was no statistically significant result or significant difference in both groups.
