Purpose: This study sought to investigate the effects of the McKenzie exercise program on forward head posture and respiratory function. Methods: Thirty adult men and women with forward head posture, aged 20-29 years, were randomly assigned to the experimental group (N=15) or the control group (N=15). Subjects in the experimental group performed the McKenzie exercises three times a week for four weeks, while subjects in the control group did not receive any intervention. Craniovertebral angle (CVA) was measured to quantify forward head posture, and forced vital capacity (FVC), FVC % predicted, forced expiratory volume at one second (FEV₁), and FEV₁ % predicted were measured to determine changes in respiratory function. The Mann-Whitney U-test was used to analyze pre-test differences in forward head posture and respiratory function between the two groups, and the Wilcoxon signed-rank test was used to analyze differences in forward head posture and respiratory function within the groups before and after intervention. The significance level (α) was set to 0.05. Results: A comparison of pre- and post-test measures showed that CVA significantly increased in the experimental group (p=0.001) denoting postural improvement, whereas no significant difference was found in the control group (p=0.053). All respiratory measures, i.e.,FVC, FVC %pred, FEV₁, and FEV₁ %pred, were significantly improved in the experimental group, whereas there were no significant differences in the control group. Conclusions: McKenzie exercise can be effective in improving forward head posture and respiratory function.

Purpose : The purpose of this study was to find out the effect of exercise on the angle and distance between scapular stability and McKenzie stretch exercise. Method : 30 volunteers took part in this experiment and we divided into three groups(experimental group A, experimental group B, control group C). Experimental group A performed scapular stabilization exercise and experimental group B performed McKenzie neck stretching exercise and control group didn't perform any exercise. Experimental group(A, B) received a total of 12 exercise session over a 4 week period (three times per week). Posture and craniovertebral angle changes of the neck using GPS measurements reported. Result : The CVA and distance change after exercise were significantly reduced in the experimental group A and B. Conclusion : Therefore, we have confirmed through experiments reducing a CVA and distance between scapular stabilization and McKenzie neck stretching exercises, whereby we would also be helpful to ensure the treatment of forward head posture.

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.

Background: This study aimed to compare the effects of the Mulligan mobilization with movement and McKenzie exercise after applying conservative physical therapy to patients with knee pain. Methods: Patients were randomly allocatied into two groups: the Mulligan mobilization with movement (10 subjects) and the McKenzie technique (10 subjects). Each group was givenr conservative physical therapy and manual therapy sessions, three times week, for four weeks. The pain intensity was measured using the visual analogue scale (VAS). The cervical range of motion (ROM) was measured with a goniometer. Balance was measured using the modified Berg balance scale (BBS). Results: After four weeks of therapy, VAS (p<.05) decreased significantly, and ROM and balance increased siginficantly in both groups(p<.05). There was a significant improvement in knee extension (p<.05) in the McKenzie group compared to the Mulligan group. No intergroup differences were found with respect to the knee flex, VAS, and BBS (p>.05). Conclusion: The McKenzie exercises are more effective than Mulligan mobilization with movement for improving knee extension. Both interventions have the same effects on pain relief, in increasing knee flexion ROM and improving balance in patients with knee pain.

PURPOSE: This study examined the effects of a horse riding simulator, gym ball, and McKenzie exercises on back pain and static balance. METHODS: Among 30 participants with chronic back pain and more than 5 points of ODI, 28 participants were selected. Groups of performing either horse riding, gym ball, or McKenzie were chosen randomly to work out two times a week for six weeks. The static balance was measured using a gym plate and the degree of pain was measured by the VAS and K-ODI. RESULTS: When each exercise was applied to back pain patients, the VAS was changed in all three groups but only in the gym-ball exercise group. The K-ODI varied in all three groups but not in the gym-ball exercise group, In the anterior - posterior static balance, all three groups showed changes, but only the riding exercise group was not significant. In the left-right static balance, all three groups were significant. CONCLUSION: This study showed that six-week exercise for back pain patients was effective in improving back pain and balance ability. Continuous exercise minimizes the risk of recurrence and is effective in preventing and treating back pain.
