Purpose: McKenzie is a widely-used and conventional clinical therapeutic exercise for patients with mechanical lower back pain. It is a well-designed assessment and classification system for the spine. Main issue: Patients with mechanical lower back pain are classified into one of three mechanical syndromes (posture, dysfunction, or derangement syndrome) by mechanical loading strategies. These methods evaluate symptomatic and mechanical responses during repeated end-range movement and sustained postures. The goal of McKenzie mechanical syndrome diagnosis is to determine directional preferences. Directional preference is a phenomenon of preference for posture or movement in one direction, which reduces or centralizes pain. However, in Korea, there is a lack of awareness of basic McKenzie mechanical syndromes diagnostic concepts. Koreans tend to think of the McKenzie method as a simple lumbar extension exercise. However, an accurate diagnosis of a mechanical syndrome must precede the application of McKenzie exercise. Conclusions: Thus, in this study, I present a classification method of McKenzie mechanical syndrome diagnosis and clinical characteristics of each mechanical syndrome.

Background: Many people are suffering from neck and shoulder pain due to muscle weakness, muscle fatigue, lack of exercise and accidents during exercise. In this study we compared the effects of McKenzie method and Mulligan technique method. Method: we randomly selected men(10) and women(10) and they are the 20s students of Busan material K college. We divided for McKenzie exercise group and Mulligan exercise group. McKenzie exercise and mulligan exercise applied cervical area three times a week for three weeks. We compared with pre-experiment and after 1~3 week through measuring the electromyography (EMG) change and neck range of motion (ROM). Results: The changes in the EMG at each exercise group, there was a statistically significant difference in each week. Although there was a significant difference after 1 week between the exercise group, the changes in the neck ROM at each exercise group there was no statistically significant difference. Conclusion: After experiment, EMG and neck ROM were increased in McKenzie exercise group and Mulligan exercise group. But Mulligan exercise group showed the change better than McKenzie exercise group in early stage. We suggest the Mulligan exercise method for recovering in early stage of neck ROM.

PURPOSE: This study tries attempted to provide basic clinical data to reduce pain and improve function by comparing the muscle fatigue of the superficial neck muscles and neck disability index (NDI) by performing McKenzie exercise or passive stretching exercise for chronic neck pain patients. METHODS: Sixteen chronic neck pain patients were selected and divided into the McKenzie group (n=8) and passive stretching group (n=8). The intervention program was performed three times a week for four weeks. The time for one exercise was 30 minutes. Before the intervention, the muscle fatigue the superficial neck muscles and NDI were measured. They were measured again after four weeks using the same method. RESULTS: The median frequency of the superficial neck muscles increased significantly in the McKenzie group and passive stretching group (p<.05). The NDI of both the McKenzie group and the passive stretching group decreased significantly. A comparison of the groups, revealed a significant difference in only the median frequency values of the upper trapezius muscle and splenius capitis muscle (p<.05). The NDI values of both groups were similar. CONCLUSION: Both McKenzie exercise and passive stretching exercises showed a significant difference in the degree of fatigue and NDI. McKenzie exercise delayed the replace of the fast twitch fibers which helped improve the muscle fatigue of the upper trapezius muscle and splenius capitis muscle. On the other hand, additional studies applying more variables for the muscle function to improve the symptom of chronic neck pain patients will be needed.

Purpose : The purpose of this study was to determine the effects of the McKenzie cervical exercise program on cervical pressure pain and balance in industrial workers. Method : The subjects, who consisted of 26 industrial workers, were randomly divided into two groups. The control group (n=13) went about their daily living routines. The other group (n=13) used the McKenzie cervical exercise program for 6 weeks (2 to 3 times/day). Pressure threshold and balance ability tests were completed before and after the experiment. The balance test was performed both with the eyes open and closed in a standing position. Result : There were significant improvements in the pressure threshold and balance ability test for the McKenzie cervical exercise program group (p<.05), while the control group showed no significant changes (p>.05). Conclusion : The above results revealed that the McKenzie cervical exercise program is effective in improving balance and cervical pressure pain.

Purpose : The purpose of this study was to compare the effect of exercise on the neck muscles activities between scapular stability and McKenzie stretch exercise in the forward head posture subjects. Method : After measuring cervical alignment using the Global Posture System, 20 volunteers with forward head posture posture were selected and divided into two groups. The experimental group A(n=15) and Experimental group B(n=15) participated in respectively and McKenzie neck stretching exercise, three times per week for 4 weeks. The scapular stabilization exercise program was comprised middle and lower trapezius strength exercises and the stretching exercise program was comprised levator scapulae and upper trapezius stretching exercise. The activities of the muscles of the posterior neck was then measured using electromyography. Result : After the intervention, there was significant difference of a electromyography activity changes between the pre-test and post-test in the experimental group. Conclusion : This study showed that both scapular stabilization and McKenzie neck stretching exercises are more effective for reducing neck muscles activities.

Objectives: In modern society, many people have low back pain (LBP) and spinal diseases. About 80% of them experience severe LBP more than once in their lifetime. We can find studies on many Korean medicine-based treatments, such as acupuncture treatment for LBP and exercise therapy, which are effective in reducing the symptoms. This study focuses on the combined effect of both Korean medicine and exercise therapy for treating LBP. Method: For this review, we searched for articles focusing on pain and disability recovery in pre-clinical and clinical studies of extension and flexion exercise therapy related to LBP. The search databases were as follows: PubMed, Google Scholar, and seven Korean electronic databases (Korea Citation Index (KCI), Korean studies Information Service System (KISS), Research Information Service System (RISS), Oriental Medicine Advanced Searching Integrated System (OASIS), DBPIA, National Digital Science Library (NDSL), and KOREAMED). The keywords were as follows: Korean Medicine, back pain, flexion exercise, extension exercise, McKenzie method, McKenzie exercise, Williams' flexion exercise, and Mechanical Diagnosis and Therapy. Results & Conclusions: This review shows the usefulness of flexion and extension exercises for LBP treatment and effective patient education, but further studies are necessary.

The purpose of this study was to determine whether extension exercise is effective in reducing low back pain. Nine patients with low back pain were randomly assigened to one of two groups-one was an experimental group in which the patient were treated with extension exercise(McKenzie method) and conservative therapy. The other was a control group in which the patients were treated with conservative therapy only. Treatment was performed for a period of ten days during Which we examed each patient three times: the first exam was done at the begining of treatment, the second after fives days, and the third after ten days. We used 'The Oswestry low back pain disability questionnaire'(r=.99) as the examination tool. The results were as follows: 1. Both experimental and control groups showed nonsignificant differences before and after treatment, and the between group difference was also non-significant(P>.05). 2. There was no effective reduction of low back pain by MecKenzie's extension exercise(p>.05). We admit that our study protocol had several shortcomings. If they had been accounted for, the result might have been different. Further study should be done with a better experimental design, a larger sample, and a longer experimental duration.

Markolf and Morris suggests that the deranged disk and torn annulus have an exellent recovery ability from the position of spine extension, where the posterior annulus is not under stress and the gel can move anterioly. McKenzie explains side gliding as a combination of rotation and side bending, his clinical studies indicate that side-gliding can gel laterally. In conclusion, the prone unilateral traction on the opposite side from the patient's pain along with the other treatment appered to have helped reduce those patient's pain. The method of treatment described in this report is suggested for Korean physical therapists who treat patients suspected of posterolateral herniated nucleus pulposus.
