Background: The purpose of this research was studying the impact of 8 weeks selected corrective exercises on neck pain, range of motion in the shoulder and neck of lifesaver women who suffering from forward head posture and myofascial pain syndrome. Methods: The method of research is semi-experimental. The population consists of 30 lifesaver women who suffering from forward head posture and myofascial pain syndrome who they placed randomly in two groups of experimental (33±2.2) and control (33±2.5). Research plan was as the pre-test and post-test with control group. The exercise protocol was carried out by experimental groups for 8 weeks, 3 sessions per week, each session lasting 45 minutes. Studied variables include myofascial pain in the neck, shoulder and neck range of motion. The mean and standard deviation were used as descriptive statistics and in the section of inferential statistics analysis of covariance was used. Results: Results of research indicated that, the protocol on the reform exercise of neck pain (P=0.001), range of motion of shoulder joint (P=0.001) and neck range of motion (P=0.001) has significant difference. Conclusion: Therefore, lifesavers women can benefit from it as a training program to improve and prevent damage caused by head forward and myofascial pain syndrome.

Normal respiration is a very intricate function that comprises mechanical as well as nonmechanical components. It is shown to be affected by various factors including age, lifestyle, disease, and change in posture. With the increased use of hand held devices, everyone is prone to poor sitting postures like forward head posture. The purpose of this study was to evaluate the effect of assumed forward head posture and torticollis on the diaphragm muscle strength. A sample of 15 healthy males, aged 18-35 years, was recruited for this study. All subjects performed spirometry to measure the forced expiratory volume in 1 second (FEV1), the forced vital capacity (FVC), and FEV1/FVC ratio. SNIP was measured during upright sitting, induced forward head posture, and torticollis. Subject’s mean age (SD) was 23(6) years. The SNIP score of the subjects during sitting with FHP was lower as compared to that during upright sitting. It decreased significantly during induced right torticollis position. This is the first study exploring the impact of different head and neck positions on respiratory function. Alteration of head and neck positions had an immediate negative impact on respiratory function. Clinicians should be prompted to assess respiratory function when assessing individuals with mal-posture.

Abstract Background: Neck pain and forward head posture are common in prolonged smartphone users and need to be targeted for treatment. We aimed to compare the effect of adding respiratory exercises to the therapeutic routine in smartphone users with forward-head posture and non-specific chronic neck pain.Mehods: Sixty patients (aged 24.7±2.1 years), were randomly assigned to the therapeutic routine (n=20), combined respiratory-exercises with therapeutic routine (n=20), or control groups (n=20). Each programme was implemented three times a week for 8 weeks. Forward head angle, pain, electromyographic activity, and respiratory patterns were measured at baseline and at 8-weeks’ post-treatment. Results: There were significant improvements in the combined group compared with the therapeutic routine group (p=0.03) for diaphragm muscle activation, (p=0.03), neck erector spinae activity (p=0.04), respiratory balance (p=0.04), and number of breaths (p=0.02). There were significant within-group changes from baseline to post-treatment in the combined group for all outcomes above, but no changes in the therapeutic exercise routine group. Outcomes for the combined group were superior to the control group in every variable. Conclusion: Combination treatment is more effective than the standard therapeutic routine. These results could be strengthened by more studies with longer follow-up assessments.Trial registration: Current Controlled Trials using the IRCT website with ID number of, IRCT20200212046469N1 “Prospectively registered” at 2020/03/04.

This systematic review and meta-analysis investigated whether the use of a lumbar roll reduced forward head posture (FHP) while sitting among individuals with or without musculoskeletal disorders. EMBASE, MEDLINE, and the Cochrane Library were systematically searched from their inception to August 2020. The quality of evidence for variables used in the meta-analysis was determined using the GRADE system. Five studies satisfied the criteria for data analysis. All studies included individuals without any spinal symptoms. Data from five studies on neck angle showed a statistically significant (p = 0.02) overall effect (standardized mean difference (SMD) = 0.77), indicating a lesser neck flexion angle while sitting with a lumbar roll than without it. Data from two studies on head angle showed a statistically significant (p = 0.04) overall effect (SMD = 0.47), indicating a lesser head extension angle while sitting with a lumbar roll than without it. In each meta-analysis, the quality of evidence was very low in the GRADE system. The use of a lumbar roll while sitting reduced FHP among individuals without spinal symptoms.
