The effect of craniocervical flexion and neck endurance exercises plus pulmonary rehabilitation on pulmonary function in spinal cord injury: a pilot single-blinded randomised controlled trial.

STUDY DESIGN: Randomised controlled trial with computerised allocation, assessor blinding and intention-to-treat analysis. OBJECTIVE: This study wanted to prove that cervicocranial flexion exercise (CCFE) and superficial neck flexor endurance training combined with common pulmonary rehabilitation is feasible for improving spinal cord injury people's pulmonary function. SETTING: Taoyuan General Hospital, Ministry of Health and Welfare: Department of Physiotherapy, Taiwan. METHOD: Thirteen individuals who had sustained spinal cord injury for less than a year were recruited and randomised assigned into two groups. The experimental group was assigned CCFEs and neck flexor endurance training plus normal cardiopulmonary rehabilitation. The control group was assigned general neck stretching exercises plus cardiopulmonary rehabilitation. Lung function parameters such as forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow rate (PEFR), inspiratory capacity (IC), dyspnoea, pain, and neck stiffness were recorded once a week as short-term outcome measure. RESULT: The experimental group showed significant time effects for FVC (pre-therapy: 80.4 ± 21.4, post-therapy: 86.9 ± 16.9, p = 0.021, 95% CI: 0.00-0.26) and PEFR (pre-therapy: 67.0 ± 33.4; post-therapy: 78.4 ± 26.9, p = 0.042, 95% CI: 0.00-0.22) after the therapy course. Furthermore, the experimental group showed significant time effects for BDI (experimental group: 6.3 ± 3.0; control group: 10.8 ± 1.6, p = 0.012, 95% CI: 0.00-0.21). CONCLUSION: The exercise regime for the experimental group could efficiently increase lung function due to the following three reasons: first, respiratory accessory muscle endurance increases through training. Second, posture becomes less kyphosis resulting increasing lung volume. Third, the ratio between superficial and deep neck flexor is more synchronised. IRB TRIAL REGISTRATION: TYGH108045.

Effects of Sling Exercise for Neck Pain: A Systematic Review and Meta-Analysis.

OBJECTIVE: The purpose of this review was to evaluate the effects of sling exercise on pain intensity, disability, and health-related quality of life in adults with neck pain. METHODS: The Cochrane Central Register of Controlled Trials, EMBASE, Physiotherapy Evidence Database (PEDro), and 6 other databases were searched from inception to July 2020. The reference lists of relevant articles to identify additional trials were also screened. Randomized controlled trials were included if they investigated the effects of sling suspension therapy in patients with neck pain, including mechanical neck disorders, cervicogenic headache, and neck disorders with radicular findings. Studies were required to be published in English or Chinese. The methodological quality and levels of evidence of studies were assessed using the PEDro scale and the Grading of Recommendations Assessment, Development and Evaluation approach, respectively. The random-effects model was used to perform meta-analyses. RESULTS: Eleven randomized controlled trials were included (n = 595). The mean total PEDro score was 4.64 (SD = 1.21) of 10, which indicated a fair methodological quality. The intervention groups showed significant improvements in pain intensity (SMD = -1.23; 95% CI = -1.88 to -0.58) immediately postintervention compared with the control groups. No significant effects were found for disability, cervical range of motion, and health-related quality of life. However, sensitivity analyses revealed significant short-term improvements in pain intensity, disability, and cervical range of motion and sustained effects on disability at intermediate-term follow-up. CONCLUSION: Sling exercise appears to be beneficial for improvements in pain intensity (moderate- to low-level evidence) among patients with neck pain. However, no definitive conclusion could be made regarding the effect of sling exercise for neck pain due to methodological limitations and high heterogeneity in the included studies. IMPACT: This review provides overall moderate- to very low-level evidence for health care professionals who may consider including sling exercise in the intervention program for patients with neck pain.
