Comparison of cervical muscle thickness between asymptomatic women with and without forward head posture.

ABSTRACT: Forward head posture (FHP) is a forward positioning of the head relative to the trunk in the sagittal plane. This posture is one of the most prevalent poor postures in patients with head and neck pain. Rehabilitative Ultrasound Imaging (RUSI) is a reliable method to objectively evaluate muscle thickness and function.To compare thickness of cervical muscles that control both head and neck posture between asymptomatic women with and without FHP.Seventy asymptomatic women aged between 20 and 40 years, with and without FHP (35 in each group), participated in the study. The thickness of the cervical muscles (rectus capitis posterior - RCP, oblique capitis superior - OCS, semispinalis capitis - SSC, sternocleidomastoid - SCM, and longus coli - LCo) was measured using RUSI and the data was compared between the two groups.The comparison of cervical muscle thickness between women with and without FHP revealed significant difference only with regard to the muscle thickness of the SCM muscle (mean difference: 0.7mm, 95% confidence interval of the difference: 0.14, 1.26mm, p value: 0.014). The thickness of this muscle was greater in women with FHP.Tonic contraction of the SCM muscle can lead to greater thickness of this muscle in subjects with FHP.

Project description:IntroductionForward head posture (FHP) is the most common postural deviation of the upper back. It is believed to be one of the predisposing factors for the development of mechanical neck pain (MNP). We propose doing a systematic review to find the effectiveness of interventions targeted on FHP with MNP and assess implementation fidelity associated with these interventions.Methods and analysisMedline (PubMed), Web of Science (Social Science Citation Index), EMBASE, Scopus, PEDro and CINAHL databases will be searched for studies published in English from their inception. Forward and backward citations of the included studies will be investigated for identifying additional records. We will include randomised controlled trials and non/quasi-experimental studies with two groups assessing the effectiveness of interventions targeted on FHP with MNP. Observational studies, non-randomised studies with single group and reviews will be excluded. We will consider the following outcome measures: postural variables of FHP, neck pain, performance-based functional disability scores of the neck, quality of life, basic activities of daily living and work-related outcomes. The unique citations will be screened by titles/abstracts and full texts, independently. The Cochrane Risk of Bias 2 tool will be used to critically appraise the included studies. The risk of bias and data abstraction of included studies will be undertaken independently. A qualitative synthesis will be conducted and, if sufficient studies with comparable outcome measures are available, we will statistically pool the result.Ethics and disseminationWe will undertake a systematic review of primary studies, and will not directly recruit participants hence, ethical clearance is not applicable. We will aim to present the findings of the completed systematic review at an international conference and subsequently submit the manuscript in a peer-reviewed journal for publication.Prospero registration numberCRD42021250310.

Project description:BackgroundBalance Body Tape (BBT) is a recently developed taping-method with the aim to reduce pain and improve posture through change in movement behavior. However, the potential effects of a treatment with BBT are scarcely documented. Therefore, the aim with this study was to investigate the effect of a three-week Balance body tape-treatment on the intensity of perceived neck, shoulder and back pain and forward head posture.MethodsIn this RCT study, subjects (n = 26), who reported being university students or having a sedentary work and experiencing pain in neck, back or shoulders, were randomized to either an intervention (n = 12) or control group (n = 14). The intervention group received a three-week treatment with BBT, the control group received no treatment. A questionnaire regarding pain, including a Numeric Rating Scale (NRS) measuring pain intensity, and a Photographic posture analysis measurement (PPAM) regarding the craniovertebral (CV) angle were assessed before and after the intervention for both groups. Wilcoxon's signed rank test and Mann-Whitney U test was used to assess intra- and between group differences respectively. The relationship between pain intensity and CV angle was assessed using Spearman's correlation.ResultsNo difference in demographic and physical characteristics between the groups were noted at baseline (p > 0.05). Pain intensity at baseline was 5 for the intervention group and 4 for the control group (p = 0.330). At follow up, the intervention group reported a lower score (NRS = 2.5, p = 0.003) whereas the control group had no significant difference in pain intensity (NRS = 3, p = 0.086). No significant change was found in the CV angle (p = 0.058) and no correlation was found between NRS and the CV angle (r = 0.102, p = 0.619).ConclusionA short treatment period with BBT may, compared to no treatment, have a small reducing effect on pain intensity in neck, back and/or shoulders. However, no effect was found on forward head posture in this study.Trial registrationRegistered retrospectively on 08/11/2021. NCT05111704 . Trial registration page link.
