Exercise interventions to improve postural malalignments in head, neck, and trunk among adolescents, adults, and older people: systematic review of randomized controlled trials.

ABSTRACT: Despite the widespread use of postural correction in exercise interventions, limited experimental evidence exists for its effectiveness. The present study aimed to systematically review the literature on the efficacy of exercise interventions in improving postural malalignment in head, neck, and trunk. A systematic review was performed by screening four scientific databases (MEDLINE, Web of Science, EBSCO, and Cochrane database) for published randomized controlled trials (RCTs) in English from 1996-2019. The review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement guidelines. Two researchers independently performed study screening, extracting data and assessing the risk of bias for each included study using the Cochrane Collaboration tool for evaluating the risk of bias. A total of 22 RCTs comprising 1,209 participants were identified for inclusion in the review. There was a high risk of bias across most of the included studies (12 studies). Only two studies were classified as low risk of bias, and eight studies were classified as moderate risk of bias. The intervention duration ranged from 2 to 13 weeks, frequency from 2 to 4 days per week, and duration of each session between 15 to 60 min. The insufficiency and quality of included studies did not allow an integrated assessment of the efficacy of exercise interventions on postural malalignments; however, the positive effects noticed in most of the studies indicate some advantages but underscores the necessity of adequately designed RCTs in this field.

Project description:BackgroundPostural balance is compromised in people with low back pain, possibly by changes in motor control of the trunk. Augmenting exercising interventions with sensor-based feedback on trunk posture and movements might improve postural balance in people with low back pain.ObjectiveWe hypothesized that exercising with feedback on trunk movements reduces sway in anterior-posterior direction during quiet standing in people with low back pain. Secondary outcomes were lumbar spine and hip movement assessed during box lift and waiter bow tasks, as well as participant-reported outcomes. Adherence to the exercising intervention was also examined.MethodsA randomized controlled trial was conducted with the intervention group receiving unsupervised home exercises with visual feedback using the Valedo Home, an exergame based on 2 inertial measurement units. The control group received no intervention. Outcomes were recorded by blinded staff during 4 visits (T1-T4) at University Hospital Zurich. The intervention group performed 9 sessions of 20 minutes in the 3 weeks between T2 and T3 and were instructed to exercise at their own convenience between T3 and T4. Postural balance was assessed on a force platform. Lumbar spine and hip angles were obtained from 3 inertial measurement units. The assessments included pain intensity, disability, quality of life, and fear of movement questionnaires.ResultsA total of 32 participants with nonspecific low back pain completed the first assessment T1, and 27 (84%) participants were randomized at T2 (n=14, 52% control and n=13, 48% intervention). Intention-to-treat analysis revealed no significant difference in change in anterior-posterior sway direction during the intervention period with a specified schedule (T2-T3) between the groups (W=99; P=.36; r=0.07). None of the outcomes showed significant change in accordance with our hypotheses. The intervention group completed a median of 61% (55/90; range 2%-99%) of the exercises in the predefined training program. Adherence was higher in the first intervention period with a specified schedule.ConclusionsThe intervention had no significant effect on postural balance or other outcomes, but the wide range of adherence and a limited sample size challenged the robustness of these conclusions. Future work should increase focus on improving adherence to digital interventions.Trial registrationClinicalTrials.gov NCT04364243; https://clinicaltrials.gov/ct2/show/NCT04364243.International registered report identifier (irrid)RR2-10.2196/26982.

Project description:BackgroundCurrent treatment for head and neck cancers (HNCs) have led to an improved survival. However, the sequelae of cancer treatment often result in trismus, or reduced mouth opening. The purpose of this report is to identify interventional studies for trismus management in HNC patients.MethodsA search of PubMed, Embase, Cumulated Index to Nursing and Allied Health Literature, and the Cochrane Library was conducted in March 2020 for randomized controlled trials (RCTs) involving interventions for trismus for head and neck cancer within 10 years. Intervention could involve the use of an exercise regime, jaw rehabilitation device, technological device, medication or massage therapy. The primary outcome was the measurement of mouth opening.ResultsEleven RCTs involving a total of 685 patients with HNC were included. Six RCTs evaluated the effectiveness of a jaw mobilization device with exercises; there was no significant benefit of an exercise regime with a jaw mobilization device either initiated before, during or after treatment compared to no exercise. Two RCTs compared 2 intervention groups that involved exercises only, with 1 study assessing the benefit of weekly supervised physical therapy with gum chewing and another evaluating the benefit of immediate (1-2 days) versus delayed (7-10 days) initiation of exercise post-surgery; there was no significant difference between groups in either study. One RCT that recruited only patients with trismus demonstrated that an exercise regime in combination with low-level laser therapy or low-intensity ultrasound had superior results in mouth opening measurements compared to exercise alone. Two RCTs compared intervention groups with and without follow-up reminders; both studies showed a significant improvement in mouth opening measurements in groups with follow-up reminders.ConclusionThis systematic review did not convey a clear consensus as to optimal intervention for trismus in HNC patients. A variety of exercise regimens and jaw rehabilitation devices appear to have comparable effectiveness. However, efforts focused on increasing adherence to a particular intervention protocol may positively impact mouth opening measures in head and neck cancer patients. Also, low-level laser therapy and low-intensity ultrasound coupled with exercise may be beneficial for patients with trismus.

Project description:Previous reviews have shown balance in older adults to be improved with exercise. However, it is currently unclear whether postural control, indicated by centre of pressure (COP) measurement, can be improved in older adults and thus whether postural control could be a mechanism to improve balance.The purpose of this systematic review was to assess the effectiveness of force platform COP variables to identify changes in postural control following exercise interventions in older adults. In addition, a secondary purpose was to determine whether the exercise types (balance, resistance or multi-component exercise interventions) are equally effective to improve postural control.Randomised controlled trials were identified using searches of databases and reference lists (PROSPERO registration number CRD42014010617). Trials performing exercise interventions, reporting force platform COP measurements, in participants with a mean age of ?60 years were included. Risk of bias assessments were performed following the Cochrane guidelines. Data were pooled in meta-analyses, and standardised mean differences (SMDs) with 95 % confidence intervals (CIs) were calculated.Twenty-three trials met the inclusion criteria for the systematic review. Twenty-two trials could be defined as either utilising a balance, resistance or multi-component exercise intervention. These 22 trials were used in the meta-analyses. All trials reported measurements of double leg stance; eight trials reported additional stance conditions. The meta-analyses of double leg stance showed that balance exercise interventions significantly decreased total sway path length/velocity [SMD -1.13, 95 % CI -1.75 to -0.51 (eyes open); SMD -0.79, 95 % CI -1.33 to -0.26 (eyes closed)] and anterior-posterior sway path length/velocity [SMD -1.02, 95 % CI -2.01 to -0.02 (eyes open); SMD -0.82, 95 % CI -1.46 to -0.17 (eyes closed)] in both eyes open and eyes closed conditions. Balance exercise interventions also decreased sway area in eyes closed conditions (SMD -0.57, 95 % CI -1.01 to -0.13) and medio-lateral sway path length/velocity in eyes open conditions (SMD -0.8, 95 % CI -1.48 to -0.12). In contrast, neither resistance nor multi-component exercise interventions affected any of the included COP measurements.Postural control is improved by balance exercise interventions. In contrast, strength or multi-component exercise interventions did not influence postural control measurements in older adults. In addition, a lack of standardisation in collection protocol and COP variables calculated across trials was identified.

Project description:BackgroundPhysical exercise is a common treatment for people with low back pain (LBP). Wearable sensors that provide feedback on body movements and posture during exercise may enhance postural balance and motor control in people with LBP.ObjectiveThis study aims to investigate whether physical exercising with postural feedback (EPF) improves postural balance, motor control, and patient-reported outcomes in people with LBP.MethodsThe study was an assessor-blinded 2×2 factorial trial. We planned to recruit 80 participants with nonspecific LBP who did not receive treatment for LBP. In addition, we aimed to recruit 40 patients with chronic, nonspecific LBP who were receiving exercise therapy (ET) at the University Hospital Zurich. Both ET patients and participants without treatment were randomized to receive either an additional EPF intervention or no additional intervention. This resulted in four different combinations of interventions: ET+EPF, ET, EPF, and no intervention. The participants underwent outcome assessments at inclusion (T1); 3 weeks later, at randomization (T2); after an intervention period of 3 weeks with a predefined exercise schedule for participants receiving EPF (T3); and after an additional 6 weeks, during which participants assigned to the EPF groups could exercise as much as they wished (T4). Patients receiving ET completed their regularly prescribed therapies during the study period. Balance was assessed during quiet standing on a force platform, and motor control was assessed during a lifting task and a waiter's bow task. Physical activity was recorded using an activity tracker and the participants' mobile phones during the study. The predefined EPF schedule consisted of nine sessions of 20 minutes of exercise with a tablet and inertial measurement unit sensors at home. Participants performed a series of trunk and hip movements and received feedback on their movements in a gamified environment displayed on the tablet.ResultsThe first participant was recruited in May 2019. Data collection was completed in October 2020, with 3 patients and 32 eligible people without therapy who passed the eligibility check.ConclusionsAlthough it will not be possible to investigate differences in patients and people without other therapies, we expect this pilot study to provide insights into the potential of EPF to improve balance in people with LBP and adherence to such interventions.International registered report identifier (irrid)DERR1-10.2196/26982.

Project description:BackgroundIn this study, the effect of adding a smartphone app to an 8-week global postural reeducation (GPR) on neck pain, endurance, quality of life, and forward head posture (FHP) in patients with chronic neck pain and FHP was evaluated.MethodsSixty male and female office workers (38.5 ± 9.1 years) with chronic neck pain were randomly assigned into three groups: group 1 (GPR+ a smartphone app, n = 20), group 2 (GPR alone, n = 20), and group 3 (the control group, n = 20). The primary outcome was pain and the secondary outcomes were disability, quality of life, endurance, and posture. Pain, disability, endurance, quality of life, and posture were evaluated using the visual analog scale (VAS), neck disability index (NDI), progressive iso-inertial lifting evaluation (PILE) test, quality of life questionnaire (SF-36), and photogrammetry, respectively, at pre-and post-8-week interventions. A one-way analysis of covariance (ANCOVA) has been conducted to statistically analyze the data.ResultsThe GPR+ a smartphone app had statistically significant improvements versus GPR alone in pain (mean difference, - 2.05 ± 0.65, ES (95% CI) - 0.50 (- 1.04 to - 0.01), P = 0.04), disability (difference = 11.5 ± 1.2, ES (95% CI) = 0.31 (0.22 to 0.97), p = 0.033), FHP (difference = 1.6 ± 0.2, ES (95% CI) = 0.31 (0.09 to 0.92), p = 0.047), and endurance (difference = 2 ± 3.3, ES (95% CI) = 0.51 (0.02 to 1.03), p = 0.039). Both of the GPR+ a smartphone app and GPR alone groups had statistically significant differences versus the control group in all outcomes.ConclusionWhen a workplace assessment and management could not be as part of any intervention, adding a smartphone app to GPR for NP may be an appropriate tool to administer a home and work exercise program resulting in elevating pain and disability, as well as improving FHP and endurance.Trial registrationCurrent Controlled Trials using the UMIN-RCT website UMIN000039720 .
