The Difference Between the Effects of the McKenzie Neck Exercise and Contract-Relax Stretching on Neck Function of Onion Peelers with Myofascial Pain Syndrome

Many jobs have health risks caused by unergonomic posture while working for a longtime. One of the disorders that often occurs is myofascial pain syndrome. If ignored,there will be a disruption in neck function. Contract-relax stretching can reduce the pain and spasm in neck muscles, while the McKenzie neck exercise can restore the cervicalintervertebral disc to its normal position and reduce neck disability. This research aimed to determine the difference in the effect
of contract-relax stretching and the McKenzie neck exercise on the neck‘s function in onion peelers with myofascial pain syndrome. The study was quasi-experimental with two groups: pre-test and post-test
design. The population was onion peelers at CV. Anita Jaya Sukses, Sidoarjo. The sample was 18 respondents who met the inclusion criteria. Data weres analyzed using the Independent Sample T-test. Based on the test, contract-relax stretching and McKenzie neck exercise obtained a significant value of 0.011(p< 0.05), so H0 is rejected and H1 is accepted. The study concluded that there was a difference in the effect of contract-relax stretching and McKenzie neck exercise on neck function in onion peelers with myofascial pain syndrome.
