Introduction and aim. Neck pain is becoming increasingly common throughout the world with a considerable impact on individuals. This study compared the effects of muscle energy techniques (MET) and static stretching (SS) on pain intensity and functional disability of patient with mechanical neck pain. Material and methods. Fifty subjects with mechanical neck pain recruited were randomly allocated into MET and SS groups equally. Subjects in MET received MET protocol, and SS groups were treated with SS; both groups had treatment twice a week for six weeks. Pain intensity and functional disability at baseline, 3rd and 6th week of treatment were measured. Descriptive and Inferential statistics were used to analyze the data. Alpha level was set at <0.05. Results. There were 12 males and 13 females for MET with age ranged between 31–53 years mean was 42.41± 7.35 years and 11 males and 14 females in SS group with age range 22–60 years and mean age of 42.91±10.44 years. There was a significant reduction in pain intensity and disability in MET’s and SS group (p<0.05) when pre-treatment, 3rd week and 6th week treatment were compared. Pain intensity was lower at SS than MET while functional disability was lower in MET than SS p<0.05 at 6th week. Conclusion. MET reduces ND more than SS and SS reduces pain intensity better MET.

The aim of the study was to compare the effect of the muscle energy technique repeated once (group A) and three times (group B), on the pain threshold and EMG parameters of the trapezius muscle. The study involved 28 people with a latent trigger point in the examined muscle. EMG was used to assess the biopotentials of the muscle during rest and shoulder lift movement. Pain threshold pressure was measured using a manual dynamometer. The examined parameters were evaluated before and after the therapy. In each group a significant increase in average pain threshold values was observed, in group A a statistically significant decrease in resting muscle tension was also observed. Other measured parameters showed no significant changes. According to the authors, one technique allows to achieve the intended therapeutic effects and does not cause too much tissue stimulation.

Celem pracy było porównanie efektu techniki energii mięśniowej powtórzonej jednokrotnie (grupa A) i trzykrotnie (grupa B), na próg bólu i parametry EMG mięśnia czworobocznego grzbietu. W badaniu udział wzięło 28 osób z utajonym punktem spustowym w badanym mięśniu. Za pomocą EMG oceniono biopotencjał mięśnia podczas spoczynku i ruchu uniesienia barków. Uciskowy próg bólu mierzono z użyciem dynamometru ręcznego. Badane parametry oceniono przed terapią i po jej zakończeniu. W każdej z grup zaobserwowano istotny wzrost średnich wartości progu bólu; w grupie A ponadto zaobserwowano statystycznie istotny spadek napięcia spoczynkowego mięśnia. Inne mierzone parametry nie wykazały istotnych zmian. Zdaniem autorów jedno wykonanie techniki pozwala osiągać zamierzone efekty terapeutyczne i nie powoduje zbyt dużego bodźcowania tkanki.
