Establishing minimal clinically important difference for effectiveness of corrective exercises on craniovertebral and shoulder angles among students with forward head posture: a clinical trial study

Impact of physical exercise (strength and stretching) on repairing craniovertebral and reducing neck pain: A systematic review and meta-analysis

Background

The craniovertebral (CV) junction is crucial for head support, mobility, and protecting the upper spinal cord and vital nerve structures. Disorders in this area can cause severe symptoms such as neck pain, restricted movement, and neurological issues such as headaches and balance problems. Exercise and physical activity improves muscle strength, flexibility, joint stability, reducing pain, and enhancing joint function, while specifically for the CV junction, exercise can relieve muscle tension, boost blood flow, and improve posture, although the specific impact on CV junction health remains underexplored.

Methods

A comprehensive literature search was conducted using databases MEDLINE, Cochrane, Lilacs, and ScienceDirect, alongside manual searches through reference lists. The review focuses on exercise and CV junction issues and includes randomized controlled trials, cohort or case-control studies, and systematic reviews. Primary outcomes include pain levels, joint mobility, function, and quality of life.

Results

Results yield four meta-analyses with corrective exercise and conventional exercise in improving forward head posture risk difference 0.00 (-0.09, 0.09) 95% confidence interval (CI), between cervical and thoracic exercises odds ratio 1.04 (0.59, 1.84) 95% CI. Comparing exercise treatment and physiotherapy showed risk difference 0.11 (-0.10, 0.32) 95% CI and the comparative analysis between training and no treatment showed risk difference 0.09 (-0.01, 0.20) 95% CI.

Conclusion

Exercise-based rehabilitation programs tailored to patients with CV junction problems offer robust evidence, benefiting clinical management, and prevention efforts.

Effects of Cervical Mobilization on Balance and Gait Parameters in Individuals With Stroke: A Randomized Controlled Trial

Stroke is a significant health problem that may result in long-term functional deficits. Balance and walking problems are among the most common post-stroke deficits, and they may negatively affect quality of life. Our aim in this study was to investigate the effects of cervical mobilization on balance and gait parameters after stroke. Participants were 24 adults (aged 30-65 years), who scored 24 or above on the Standardized Mini-Mental State Exam (MMSE) and no more than 3 on the Modified Rankin scale. Participants were randomly assigned to either an experimental Bobath therapy and cervical mobilization group (n = 12) or a control group who received Bobath therapy and a sham application (n = 12). Both groups received 60 minutes of Bobath therapy three times a week for four weeks; additionally, the experimental group received 15 minutes of cervical mobilization in each session, while the control group received 15 minutes of spinal sham mobilization each session. Pre and post treatment, we assessed all participants' demographic characteristics, gait parameters, balance parameters, and forward head posture values using a clinical data assessment form, spatiotemporal gait analysis (LEGSystm), portable computerized kinesthetic balance device (SportKAT 550), and craniovertebral angle (CVA), respectively. The groups showed no significant differences in their initial demographic and clinical characteristics (age, sex, stroke duration and disability levels.). In comparing changes on variables of interest, we observed significant experimental versus control group improvements in balance parameters except for their left side balance score (right side, left side, forward, backward and total balance scores were significant at p = .003, p = .089, p < .001, p = .022, p < .001, respectively), gait parameters (stride number, stride length, stride time, stride velocity, cadance at p = .007, p = .019, p = .013, p = .005, p = .001, respectively) and CVA (p < .001). Also, there were findings in favor of the experimental group on the modified timed up and go test on walk out, mid turn, walk back and total times (p = .028, p = .001, p = .016, and p = .001, respectively),but not for sit-to-stand time or stand-to-sit time. Clinicians involved in stroke rehabilitation should assess and treat the cervical region to enhance rehabilitation effectiveness.

Effects of telerehabilitation-based respiratory and corrective exercises among the elderly with thoracic hyper-kyphosis: a clinical trial

BACKGROUND

Aging is associated with changes in the musculoskeletal system, including increased susceptibility to spine malalignments. Utilizing corrective exercises with a therapeutic emphasis can be beneficial in the elderly with thoracic spine hyperkyphosis.

OBJECTIVE

This study aimed to investigate the effects of six weeks of telerehabilitation-based respiratory and corrective exercises on quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and chest expansion in the elderly with thoracic spine hyperkyphosis.

METHODS

In this clinical trial, a total of 40 participants aged 60 and above with thoracic hyperkyphosis were randomly divided into the control (N = 20) and experimental (N = 20) groups. The experimental group performed the corrective exercises for six weeks (3 sessions per week). The control group performed general stretching exercises during the same time period. We measured the outcomes of quality of life, disability, thoracic kyphosis, craniovertebral angle, shoulder angle, cranial angle, and lung expansion before and after the intervention. Analysis of covariance (ANCOVA) was employed to analyze the data. A P-value ≤ 0.05 was considered statistically significant.

RESULTS

Quality of life (P < 0.001, Effect Size (ES): 0.44), chest expansion (P < 0.001, ES: 0.56), thoracic kyphosis angle (P < 0.001, ES: 0.31), craniovertebral (P < 0.001, ES: 0.33), cranial (P < 0.001, ES: 0.38), and shoulder (P = 0.005, ES: 0.20) angles were significantly improved in the experimental group as compared with controls. However, no statistically significant difference was observed between the two groups in terms of physical ability (P = 0.251, ES: 0.04).

CONCLUSION

It is therefore recommended that online corrective exercises be used in the rehabilitation protocol to improve the quality of life, posture, chest expansion, and disability in the elderly with thoracic kyphosis.
