Abstract

Introduction: High prevalence of neck pain has become an important health complain among dental practitioners which is followed by reduced working performance, burnout and early retirement. The purpose of this study is to assess the relationship between individual and occupational risk factors as well as forward head posture (FHP) with dentist’s neck pain and to determine the priority of these factors in the development of the neck pain.

Material and Methods: In this cross - sectional study, 70 dentists of two dental centers in Tehran were examined with clinical testing of FHP. Individual and job characteristics were collected by means of a questionnaire. The visual analog scale (VAS) was applied in order to determine the severity of pain in various parts of the body. Spearman and Pearson correlation coefficient and multiple linear regressions were used to examine the relationship and effect of the studied variables in creating the neck pain.

Results: According to the results, neck was the most painful part of the body (66.6%). Indeed, 40 (57.1%) of participating dentists were suffering from the forward head posture. The results of the multiple linear regression showed that the FHP with the standard coefficient (β= 0.64) was the most influential factor in predicting the incidence of neck pain.

Conclusion: The FHP has a greater impact than any other individual and job factors in creating neck pain. It may be concluded that awkward neck posture is the most important risk factor for neck pain in static sitting jobs such as dentistry.

Abstract
Objectives: Work-induced musculoskeletal pain disorders are among the most common problems among workers. This study aimed to compare fatigue and trunk and neck postures during work in tailors with and without nonspecific chronic neck pain.
Methods: In this cross-sectional study, 30 sewing machine operators participated voluntarily and were divided in two groups of people with (15 persons) and without (15 persons) chronic nonspecific neck pain. The craniovertebral, cranial, and shoulder angles were calculated three intervals (at the start of work, after 2 hours of continuous work, after 4 hours of continuous work) using the photogrammetric method. Borg scale was used to examine work-induced fatigue. A one-way repeated measure analysis of variance at the significance level of 0.05 was used for data analysis.
Results: There were significant differences in craniovertebral, cranial, and shoulder angle changes (P < 0.001) between the two groups while working. Postural trunk and neck changes were more evident in the nonspecific chronic neck pain group. However, there were no significant differences in terms of fatigue levels between the two groups (P = 0.639).
Conclusion: The upper trunk related posture among workers with nonspecific chronic neck pain may be more negatively affected during work. So it is suggested that maintaining proper posture should be more emphasized among these workers.

Volume 10, Issue 4 (3-2023)
Abstract
Objectives: Neck pain is one of the most common musculoskeletal disorders among smartphone users. The purpose of the present study was to compare the immediate effects of rest and McKenzie exercise on pain level and disability index among individuals who complained of pain and discomfort in the neck after using a smartphone.
Methods: Ten males and 14 females with an average age of 25.71 years, who complained of pain and discomfort in the neck after using a smartphone, participated in this clinical trial study. During two consecutive days, they received conservative interventions including rest and Mackenzie exercise. The duration of each intervention was one session. The level of pain and disability was measured with the visual analog scale (VAS) and the neck disability index questionnaire before starting the treatment (immediately after using the smartphone), and after performing rest interventions and McKenzie exercises. The data were analyzed by ANOVA with repeated measures (P < 0.05).
Results: Subjects reported lower levels of pain and disability following both intervention methods (rest and McKenzie exercise) compared to before the start of the treatment period. The Cohen's d effect size index showed the high effectiveness of Mckenzie's exercise compared to the resting condition on the level of pain and disability.
Conclusion: The results of this study showed that McKenzie's exercise can more effectively decrease the amount of pain and disability in the neck and shoulder areas following the use of a smartphone compared to rest.

Volume 11, Issue 1 (5-2023)
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
Yousef Ghanbari, Farzaneh Gandomi,
Volume 11, Issue 3 (12-2023)
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.
