Abstract
Objectives: Chronic neck pain is one of the most common musculoskeletal disorders that has a great impact on people's quality of life, health, and work efficiency. Due to the high costs of drug treatments, the search for simple and low-cost treatment solutions is inevitable. Stretching and tissue release techniques are effective solutions for correcting skeletal-muscular disorders. Therefore, this study aimed to investigate their effectiveness in controlling pain and improving the performance of people suffering from non-specific chronic neck pain.
Methods: In this semi-experimental study with parallel groups and pre-test-post-test design, 39 patients with non-specific chronic neck pain with an average age of 25 to 45 years, in a non-random and available form, were selected from the office workers. Individuals were randomly assigned into three groups of traction stretch, release, and control, and received interventions for six weeks. At the beginning and after the completion of the interventions, pain intensity, qualitative fatigue, and quality of life were evaluated using the visual measure of pain, multidimensional fatigue questionnaire, and SF36 questionnaire, respectively. To compare the averages, one way ANCOVA a mixed analysis of variance test was used.
Results: Intra-group comparisons showed that pain intensity, quality of life, and fatigue improved significantly in both intervention groups (P<0.05). Stretching and release exercises both had a significant effect on improving the variables (P<0.05). However, the results of the release exercises group were more significant.
Conclusion: Six weeks of releasing and stretching techniques in non-specific chronic neck pain patients reduces pain and fatigue and increases their quality of life.

Comparative Analysis of the Effect of Six Weeks Online Corrective Exercises and Posture Retraining on Pain, Disability, Percieved Fatigue, and Mental Workload Among Dentists in Shahrekord

Abstract
Objectives: Musculoskeletal disorders and associated pains are represent significant and prevalent factors contributing to occupational injuries. The aim of this study was to investigate the effect of online upper cross syndrome-based exercises and the posture retraining on pain, disability, fatigue, and mental workload of experienced by dentists in Shahrekord city.
Methods: A total of 33 dentists were selected as the statistical sample and randomly assigned to three groups including, control (n = 11), Online National Academy of Sports Medicine (NASM) based corrective exercises (n=11), and posture retraining (n=11) groups. Baseline assessments were conducted, and outcomes were examined immidietly after the interventions. The experimental groups underwent the study interventions for six weeks, while the control group maintained their regular daily activities during this period. Primary outcome measure was pain, and secondary measures included disability, perceptual fatigue, mental workload, and quality of life. Within-group comparisons were analyzed using paired sample t-tests, and between-group comparisons utilized one-way analysis of variance.
Results: The results indicated that both exercise interventions positively affected pain, disability, perceptual fatigue, mental workload, and quality of life among dentists (P<0.05). Notably, correction of the upper crossed syndrome demonstrated a more significant effect compared to the posture retraining intervention (P<0.05).
Conclusion: The utilization of online NASM-based corrective exercises and posture retraining could have positive effects in reducing pain and disability and also improving the overall performance of dentists.
