Posterior neck weighting an innovative and novel head orthosis for forward head posture correction: Randomized controlled trial

Background

Muscle activity of the anterior and posterior elements of the cervical spine, both together actively contribute to the balance of the head position over the neck. Increasing muscular tension of the one cervical muscle group could induce poor motor control of cervical spine joints, this might contribute to the anterior position of the head with neck, known as forward head posture (FHP). We propose posterior neck weighting as an innovative orthosis to correct head posture within FHP participants and improve co-related mechanical neck pain.

Methods

Sixty-one participants with FHP; were randomly assigned to one of two groups posterior cervical weighing orthosis (PCWO) or deep cervical flexion (DCF) exercise. Each participant has been assessed for change in Craniovertebral Angle (CVA) as an indicator for FHP severity, and neck disability index (NDI).

Results

Wilcoxon Signed Rank Test showed a statistically significant change difference regarding the degree of CVA improvements, and the score of NDI of pre-and post-intervention of the PCWO group (p < 0.0001), (p < 0.0001), and of the DCF group (p < 0.0001), (p = 0.0039), respectively. Mann-Whitney Test, showed a statistically significant difference between groups for CVA improvement (p < 0.0001), and NDI (p = 0.045). No correlation between CVA and NDI scores within the PCWO group (r = 0.129, p = 0.473), and within the DCF exercise group (r = 0.073, p = 0.71).

Conclusion

PCWO is a novel and innovative neck orthosis that is considered a promising intervention to correct FHP and improve correlated neck disability.

Efficacy of head postural correction program on craniovertebral angle, scapular position, and dominant hand grip strength in forward head posture subjects: A randomized controlled trial

OBJECTIVE

Forward head posture (FHP) is a common postural disorder that alters shoulder function. This study examined the efficacy of a corrective program involving postural correction exercises (PCEs), scapular stabilization exercises (SSEs), and kinesiotaping (KT) on improving craniovertebral angle (CVA), scapular position, and dominant hand grip strength (HGS) in individuals with FHP.

METHODS

Sixty subjects (8 males and 52 females, 18-40 years old) were randomly allocated into four equal groups: Group A: received PCEs only, Group B: received PCEs and SSEs, Group C: received PCEs and KT, Group D: received PCEs, SSEs and KT. All subjects received treatment for 4 weeks (4 times/week) and postural advice. Outcome measures included cranio-vertebral angle (CVA), scapular position using Lateral Scapular Slide Test and dominant HGS using a CAMRY dynamometer that were assessed at baseline and 4 weeks post intervention.

RESULTS

Comparing all groups post training revealed that there were statistically significant increases (p < 0.05) in all measured variables (CVA, scapular position and dominant HGS) in favor of group (D).

CONCLUSION

Combination of PCEs, SSEs and KT interventions has achieved the best gains in terms of CVA, dominant HGS and regaining optimal scapular position in FHP subjects.

Therapeutic exercises for idiopathic scoliosis in adolescents

BACKGROUND

Adolescent idiopathic scoliosis (AIS) is a pathology that changes the three-dimensional shape of the spine and trunk. While AIS can progress during growth and cause cosmetic issues, it is usually asymptomatic. However, a final spinal curvature above the critical threshold of 30° increases the risk of health problems and curve progression in adulthood. The use of therapeutic exercises (TEs) to reduce the progression of AIS and delay or avoid other, more invasive treatments is still controversial.

OBJECTIVES

To evaluate the effectiveness of TE, including generic therapeutic exercises (GTE) and physiotherapeutic scoliosis-specific exercises (PSSE) in treating AIS, compared to no treatment, other non-surgical treatments, or between treatments.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, four other databases, and two clinical trials registers to 17 November 2022. We also screened reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing TE with no treatment, other non-surgical treatments (braces, electrical stimulation, manual therapy), and different types of exercises. In the previous version of the review, we also included observational studies. We did not include observational studies in this update since we found sufficient RCTs to address our study aims.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology. Our major outcomes were progression of scoliosis (measured by Cobb angle, trunk rotation, progression, bracing, surgery), cosmetic issues (measured by surface measurements and perception), and quality of life (QoL). Our minor outcomes were back pain, mental health, and adverse effects.

MAIN RESULTS

We included 13 RCTs (583 participants). The percentage of females ranged from 50% to 100%; mean age ranged from 12 to 15 years. Studies included participants with Cobb angles from low to severe. We judged 61% of the studies at low risk for random sequence generation and 46% at low risk for allocation concealment. None of the studies could blind participants and personnel. We judged the subjective outcomes at high risk of performance and detection bias, and the objective outcomes at high risk of detection bias in six studies and at low risk of bias in the other six studies. One study did not assess any objective outcomes. Comparing TE versus no treatment, we are very uncertain whether TE reduces the Cobb angle (mean difference (MD) -3.6°, 95% confidence interval (CI) -5.6 to -1.7; 2 studies, 52 participants). Low-certainty evidence indicates PSSE makes little or no difference in the angle of trunk rotation (ATR) (MD -0.8°, 95% CI -3.8 to 2.1; 1 study, 45 participants), may reduce the waist asymmetry slightly (MD -0.5 cm, 95% CI -0.8 to -0.3; 1 study, 45 participants), and may result in little to no difference in the score of cosmetic issues measured by the Spinal Appearance Questionnaire (SAQ) General (MD 0.7 points, 95% CI -0.1 to 1.4; 1 study, 16 participants). PSSE may result in little to no difference in self-image measured by the Scoliosis Research Society - 22 Patient Questionnaire (SRS-22) (MD 0.3 points, 95% CI -0.3 to 0.9; 1 study, 16 participants) and improve QoL slightly measured by SRS-22 Total score (MD 0.3 points, 95% CI 0.1 to 0.4; 2 studies, 61 participants). Only Cobb angle results were clinically meaningful. Comparing PSSE plus bracing versus bracing, low-certainty evidence indicates PSSE plus bracing may reduce Cobb angle (-2.2°, 95% CI -3.8 to -0.7; 2 studies, 84 participants). Comparing GTE plus other non-surgical interventions versus other non-surgical interventions, low-certainty evidence indicates GTE plus other non-surgical interventions may reduce Cobb angle (MD -8.0°, 95% CI -11.5 to -4.5; 1 study, 80 participants). We are uncertain whether PSSE plus other non-surgical interventions versus other non-surgical interventions reduces Cobb angle (MD -7.8°, 95% CI -12.5 to -3.1; 1 study, 18 participants) and ATR (MD -8.0°, 95% CI -12.7 to -3.3; 1 study, 18 participants). PSSE plus bracing versus bracing alone may make little to no difference in subjective measurement of cosmetic issues as measured by SAQ General (-0.2 points, 95% CI -0.9 to 0.5; 1 study, 34 participants), self-image score as measured by SRS-22 Self-Image (MD 0.1 points, 95% CI -0.3 to 0.5; 1 study, 34 participants), and QoL measured by SRS-22 Total score (MD 0.2 points, 95% CI -0.1 to 0.5; 1 study, 34 participants). None of these results were clinically meaningful. Comparing TE versus bracing, we are very uncertain whether PSSE allows progression of Cobb angle (MD 2.7°, 95% CI 0.3 to 5.0; 1 study, 60 participants), changes self-image measured by SRS-22 Self-Image (MD 0.1 points, 95% CI -1.0 to 1.1; 1 study, 60 participants), and QoL measured by SRS-22 Total score (MD 3.2 points, 95% CI 2.1 to 4.2; 1 study, 60 participants). None of these results were clinically meaningful. Comparing PSSE with GTE, we are uncertain whether PSSE makes little or no difference in Cobb angle (MD -3.0°, 95% CI -8.2 to 2.1; 4 studies, 192 participants; very low-certainty evidence). PSSE probably reduces ATR (clinically meaningful) (MD -3.0°, 95% CI -3.4 to -2.5; 2 studies, 138 participants). We are uncertain about the effect of PSSE on QoL measured by SRS-22 Total score (MD 0.26 points, 95% CI 0.11 to 0.62; 3 studies, 168 participants) and on self-image measured by SRS-22 Self-Image and Walter Reed Visual Assessment Scale (standardised mean difference (SMD) 0.77, 95% CI -0.61 to 2.14; 3 studies, 168 participants). Further, low-certainty evidence indicates that 38/100 people receiving GTE may progress more than 5° Cobb versus 7/100 receiving PSSE (risk ratio (RR) 0.19, 95% CI -0.67 to 0.52; 1 study, 110 participants). None of the included studies assessed adverse effects.

AUTHORS' CONCLUSIONS

The evidence on the efficacy of TE is currently sparse due to heterogeneity, small sample size, and many different comparisons. We found only one study following participants to the end of growth showing the efficacy of PSSE over TE. This result was weakened by adding studies with short-term results and unclear preparation of treating physiotherapists. More RCTs are needed to strengthen the current evidence and study other highly clinically relevant outcomes such as QoL, psychological and cosmetic issues, and back pain.

A Preliminary Diagnostic Model for Forward Head Posture among Adolescents Using Forward Neck Tilt Angle and Radiographic Sagittal Alignment Parameters

Despite numerous attempts to correct forward head posture (FHP), definitive evidence-based screening and diagnostic methods remain elusive. This study proposes a preliminary diagnostic methodology for FHP, utilizing a noninvasive body angle measurement system as a screening test for FHP and incorporating radiological parameters for sagittal alignment. We enrolled 145 adolescents for FHP screening. The forward neck tilt angle (FNTA), defined as the angle between the vertical line and the line connecting the participant's acromion and tragus, was measured using the POM-Checker (a noninvasive depth sensor-based body angle measurement system). A whole-spine standing lateral radiograph was obtained, and eight sagittal alignment parameters were measured. Statistical analyses of the association between the FNTA and eight sagittal alignment parameters were conducted. We used 70% of the participant data to establish a preliminary diagnostic model for FHP based on FNTA and each sagittal alignment parameter. The accuracy of the model was evaluated using the remaining 30% of the participant data. All radiological parameters of sagittal alignment showed weak statistical significance with respect to FNTA (best case: r = 0.16, p = 0.0500; cranial tilt). The proposed preliminary diagnostic model for FHP demonstrated 95.35% agreement. Notably, the model using FNTA without radiological parameters accurately identified (100%) participants who required radiographic scanning for FHP diagnosis. Owing to the weak statistical significance of the association between radiological parameters and external body angle, both factors must be considered for accurate FHP diagnosis. When a clear and severe angle variation is observed in an external body angle check, medical professionals should perform radiographic scanning for an accurate FHP diagnosis. In conclusion, FNTA assessment of FNTA through the proposed preliminary diagnostic model is a significant screening factor for selecting participants who must undergo radiographic scanning so that a diagnosis of FHP can be obtained.

Effects of cervical stabilization with visual feedback on craniovertebral angle and proprioception for the subjects with forward head posture

BACKGROUND

This study aimed to identify the effect of cervical stabilization exercise with visual feedback on the craniovertebral angle and proprioception in subjects with forward head posture.

METHODS

Thirty healthy adults were recruited in the study. Participants were randomly assigned to the stabilization exercise with visual feedback (SE-VF) group (N = 15) or stabilization exercise group (N = 15). The SE-VF group performed cervical stabilization exercise while sitting on a chair without a backrest and checking their side profile in real-time via a monitor 3-m away. The stabilization exercise group performed the same cervical stabilization exercise as the SE-VF group but without visual feedback. Craniovertebral angle (CVA) was measured to quantify forward head posture, and the proprioception of the subjects was evaluated.

RESULTS

There was a significant interaction between group and time in CVA and proprioception (P < .05). Additionally, there was no significant difference pre-intervention between the groups (P > .05); however, there was a significant difference post-intervention (P < .05) in CVA and proprioception.

CONCLUSION

The findings of this study showed that the cervical stabilization exercise with visual feedback was effective for the proprioception of subjects. Moreover, the results suggest that visual feedback is effective in cervical stabilization exercise.

Systematic review and meta-analysis on efficacy of various exercise programs to improve postural parameters, pain and disability in neck

Forward head posture is a common abnormal posture characterised by weakness of muscle around neck and shoulder. Persistent forward head posture can impair respiratory functions and cervical proprioception. The aim of this systematic review and meta-analysis is to determine the effectiveness of exercises to improve the forward head posture. The online literature search performed on various databases, i.e. PubMed, Cochrane, PEDro, Science Direct and Scopus databases resulted in 601 articles, but only 11 articles were found relevant to perform meta-analysis. The primary outcome measure was craniovertebral angle and other outcome measures were neck pain, cranial angle, cranial rotation angle and Neck Disability Index (NDI). Methodological quality of studies was assessed by PEDro scoring and risk of bias assessment was performed using Cochrane collaboration tool of risk of bias. Results of meta-analysis revealed that craniovertebral angle (CVA), cranial rotation angle (CRA), visual analogue scale and NDI improved significantly (P<0.00001) in forward head posture participants who followed any type of exercise regime compared to the participants who did not follow any exercise program. However, cranial angle was not found significantly (P=0.73) improved in exercise groups. Exercises are effective in improving postural parameters, such as CVA, CRA and pain and neck disability in subjects with forward head posture.

A Comparison of Two Forward Head Posture Corrective Approaches in Elderly with Chronic Non-Specific Neck Pain: A Randomized Controlled Study

Forward head posture (FHP) is a common postural displacement that is significantly associated with neck pain, with higher risks of having neck pain in female and older populations. This study investigated the effect of two different forward head posture (FHP) interventions in elderly participants with poor posture and non-specific neck pain. Sixty-six elderly participants with a craniovertebral angle (CVA) < 50° were randomized into either a Chiropractic Biophyics® (CBP®) or a standardized exercise based FHP correction group (Standard Group). Both groups were treated for 18 sessions over a 6-week period. A 3-month post-treatment follow-up was also assessed with no further interventions. The CBP group received a mirror image® exercise and a Denneroll™ cervical traction orthotic (DCTO); the standard group performed a protocol of commonly used stretching and strengthening exercises for the neck. Both groups received 30 min of their respective interventions per session. The primary outcome was the CVA, with secondary outcomes including pain intensity, Berg balance score (BBS), head repositioning accuracy (HRA), and cervical range of motion (CROM). After 18 sessions (6 weeks later), the CBP group had statistically significant improvement in the CVA (p < 0.001), whereas the standard group did not. In contrast, both groups showed improved functional measurements on the BBS and HRA as well as improved pain intensity. However, at the 3-month follow-up (with no further treatment), there were statistically significant differences favoring the CBP group for all outcomes (p < 0.001). The differences in the between group outcomes at the 3-month follow-up indicated that the improved outcomes were maintained in the CBP group, while the standard group experienced regression of the initially improved outcomes at 6 weeks. It is suggested that the improvement in the postural CVA (in the CBP group but not in the standard group) is the driver of superior and maintained pain and functional outcomes.

The relation of forward head posture with back muscle endurance in primary school children: a cross-sectional study

Background

The goal of this study was to look at the correlation between forwarding head posture and back muscle endurance in 288 primary school healthy active children aged 7–10 years old in public schools in Sheblanga, Benha, Qalubyia governorate (170 boys and 118 girls).

Methods

A cross-sectional study was conducted on elementary school children to see whether there was a link between forwarding head posture and back muscle endurance. The photogrammetry technique of craniovertebral angle (CVA) was employed to quantify forward head position, and the Biering Sorensen test was utilized to evaluate isometric back muscle endurance.

Results

The distribution of head posture in the study group revealed 132 (46%) children with advancing head posture and 156 (54%) children with normal posture. In the study group, the connection between CVA and trunk extensor endurance was moderately significant (r = 0.4, p = 0.0001). The trunk extensor endurance of children with advancing heads was significantly lower than that of children with normal postures (p = 0.0001).

Conclusions

There is a link between forwarding head posture (FHP) and back muscle endurance.

Physiotherapeutic Scoliosis-Specific Exercise Methodologies Used for Conservative Treatment of Adolescent Idiopathic Scoliosis, and Their Effectiveness: An Extended Literature Review of Current Research and Practice

Due to the multifactorial etiology of scoliosis, a comprehensive treatment plan is essential for conservative management. Physiotherapeutic scoliosis-specific exercise (PSSE) methods have lately gained popularity for the conservative treatment of scoliosis. The aim of this study was to analyze the PSSE methodologies used for conservative treatment of adolescent idiopathic scoliosis (AIS), as well as their effectiveness. The study was based on an extended literature search conducted in the PubMed, Google Scholar, PEDro, eLABA, and BioMed Central databases. A total of 123 articles were selected for this study (including articles overviewed in systematic reviews and meta-analyses) after applying the inclusion criteria. The study revealed that inappropriate management of AIS could result in serious health problems. Conservative interventions that aid in stabilizing spine curvature and improving esthetics are preferred for scoliosis treatment. Bracing has traditionally been the mainstay of treatment, but growing evidence suggests that PSSE physiotherapy allows effective management of idiopathic adolescent scoliosis. Currently, there are the following PSSE physiotherapy schools in Europe: Schroth, SEAS, BSPTS, FED, FITS, Lyon, Side Shift, and DoboMed. The methodologies of these schools are similar, in that they focus on applying corrective exercises in three planes, developing stability and balance, breathing exercises, and posture awareness. Although high-quality research supporting the effectiveness of PSSE physiotherapy in the treatment of AIS is lacking, existing evidence indicates that PSSE physiotherapy helps to stabilize spinal deformity and improve patients’ quality of life. Among the abovementioned methodologies, Schroth is the most widely studied and has been proven to be effective. However, both SEAS and BSPTS effectively stabilize and even reduce the Cobb angle of scoliosis. Data supporting the validity of other methodologies are very limited. Only the Schroth method significantly reduces the angle of trunk rotation, while both SEAS and Schroth methods greatly improve the quality of life indicators. In any case, the available evidence is insufficient to confirm the advantage of one specific physiotherapy technique over others.

Differences in upper body posture between individuals with and without chronic idiopathic neck pain during computerised device use: A 3D motion analysis study

BACKGROUND

Computer use is associated with poor postures and increased risk of developing neck pain. Evaluating differences in working posture of individuals with and without chronic neck pain may assist the development of strategies to lessen or prevent pain.

OBJECTIVE

To identify if upper body kinematics differs between individuals with and without chronic idiopathic neck pain during four conditions (tablet, laptop, and desktop computer sitting and standing).

METHODS

Three-dimensional (3D) motion capture measured upper body kinematics in 44 individuals with chronic idiopathic neck pain > 90 days (Cases n = 22) and without pain (Control n = 22), during a typing task under four conditions: tablet, laptop, desktop computer (sitting and standing). Differences between groups were evaluated using generalised linear mixed models.

RESULTS

Across all conditions and compared to controls, cases had significantly less flexion between their head-neck and upper trunk segments (between group mean difference 7.15°, 2.1, 12.2, p = .006), greater upper trunk flexion relative to the laboratory (-6.15°, -10.9, -1.3, p = .012), greater shoulder flexion bilaterally (left 12.35°, 6.7, 17.9, p < .001; right 13.49°, 7.9, 19.1, p < .001) and less right elbow flexion (-6.87°, -12.1, -1.7, p = .010). Approaching significance, the case group had less left elbow flexion (between group mean difference -5.36°, -10.9, 0.1, p = .056) and a smaller mean craniocervical angle for the seated desktop condition (group x condition interaction -6.37°; 95% CI -12.7, -0.1, p = .052).

SIGNIFICANCE

Individuals with neck pain consistently used different upper body postures compared to individuals without pain when working on computerised devices under varying workstation conditions. This finding suggests that people with neck pain work in potentially aggravating postures that may be associated with their pain.

Corrective exercise-based therapy for adolescent idiopathic scoliosis: Systematic review and meta-analysis

OBJECTIVE

to analyze the efficacy of Corrective exercise-based therapy in the improvement of deformity and quality of life in adolescent idiopathic scoliosis.

DATA SOURCES

PubMed Medline, Scopus, Web of Science (WOS), Physiotherapy Evidence Database, CINAHL Complete and SciELO, until June 2021.

REVIEW METHODS

Randomized controlled trials was selected, including participants diagnosed with adolescent idiopathic scoliosis, in which the experimental group received Corrective exercise-based therapy. Two authors independently searched the scientific literature in the data sources, extracted the data and assessed the risk of bias. A pairwise meta-analysis using the random-effects model was performed.

RESULTS

Eight randomized controlled trials providing data from 279 adolescent idiopathic scoliosis patients were included. Seven randomized controlled trials including 236 patients showed moderate-quality evidence for a medium effect (SMD = -0.52, 95% CI -0.96 to -0.1), favoring corrective exercise-based therapy for spinal deformity reduction. Corrective exercise-based therapy was better than no intervention (SMD = -0.59, 95% CI -1.18 to -0.01) but similar to other intervention (SMD = -0.2, 95% CI -0.67 to 0.27), and a medium effect was found (SMD = -0.51, 95% CI -0.89 to -0.13) when corrective exercise-based therapy was used with other therapies. Four studies including 151 patients showed low-quality evidence of a large effect of Corrective exercise-based therapy on Scoliosis Research Society measurement (SRS-22) total score improvement (SMD = 1.16, 95% CI 0.36 to 1.95).

CONCLUSION

In mild and moderate adolescent idiopathic scoliosis patients, corrective exercise-based therapy could be used to reduce spinal deformity and to improve quality of life as isolated treatment or as coadjuvant treatment combined with other therapeutic resources.

Does restoration of sagittal cervical alignment improve cervicogenic headache pain and disability: A 2-year pilot randomized controlled trial

BACKGROUND

To investigate the feasibility and effect of a multimodal program for improving chronic cervicogenic headache (CGH) via the addition of sagittal cervical spine alignment correction.

DESIGN

Pilot, parallel-group, randomized controlled trial.

PARTICIPANTS

60 patients with CGH, straightening of the cervical lordosis, and forward head posture (FHP) were randomly assigned using permuted-block randomization either to a control (n = 30) or an experimental group (n = 30).

INTERVENTIONS

Subjects in both groups received a multimodal program where the denneroll cervical spine extension traction orthotic was added to the experimental group only. Feasibility was assessed through recruitment rate, compliance rate, adherence rate, safety, and global satisfaction in addition to clinical outcome measures: FHP distance, cervical lordosis, headache frequency, headache disability inventory (HDI), headache impact test-6 (HIT-6), and daily defined dose (DDD). Evaluations were performed at: baseline, 10 weeks, 1 year follow up, and 2-year follow up. The assessor was blind to group allocation for all measured outcomes.

RESULTS

The recruitment rate was 60%, 78 % out of them completed the entire study. The recruited participants complied with 98% of the required visits. No adverse events were recorded and greater overall satisfaction with the interventions was reported. Greater improvements were found for the experimental group's cervical lordosis (f = 259.9, P< < .001) and FHP (f = 142.5, P< < .001). At 10 weeks, both groups showed equal improvements in CGH outcomes: headache frequency (P = 0.07), HDI (P = 0.07), HIT-6 (P = .2), and DDD (P = .3). In contrast, at the 1-year and 2-year follow up, between group differences were found for all CGH outcomes, P < .00, indicating greater improvement in the experimental group.

CONCLUSION

The results indicated feasibility for recruitment rate, compliance rate, exercise session adherence, safety, and global satisfaction. At 1-year and 2-year follow-up, the addition of the denneroll orthotic device revealed positive influence on CGH management outcomes.

TRIAL REGISTRATION

The trial was retrospectively registered with the Pan African Clinical Trial Registry (PACTR201605001650300).

The effects of exercise therapy on adolescent idiopathic scoliosis: An overview of systematic reviews and meta-analyses

BACKGROUND

Exercise therapy was suggested as an appealing treatment option for Adolescent Idiopathic Scoliosis (AIS) patients with less side effects, lower economic costs, and more psychological benefits. Nevertheless, no unanimous findings about the efficacy of exercise therapy have been obtained from previous systematic reviews and/or meta-analyses.

OBJECTIVE

To provide an overview of previous systematic reviews and/or meta-analyses on the effectiveness of exercise therapy on AIS treatment.

METHODS

Systematic searches in Medline, Eric, CINAHL, Embase, SPORTDiscus, PsycINFO, and the Cochrane Library for systematic reviews and/or meta-analyses of randomized controlled trials (RCTs), non-randomized comparison studies (NRS) or observational studies using exercise as an intervention, and with outcome measures including Cobb angle, angle of trunk rotation (ATR), and quality of life. The methodological quality of the review articles was evaluated by A Measurement Tool to Assess Systematic Reviews (AMSTAR) checklist.

RESULTS

Ten systematic reviews and meta-analyses were included. The quality of most of the review articles is moderate with a mean score of 6/11 on the AMSTAR scale. Overall, there is increasing evidence showing the efficacy of exercise therapy on reducing the Cobb angle and angle of trunk rotation, and improving perceived quality of life.

CONCLUSION

Exercise therapy was found to have potential benefits to treat physiological and psychological aspects of AIS patients. However, the findings were not conclusive given that some reviews relied on data from the trials with potential risk of bias and significant heterogeneity. More high-quality research is still needed to verify these findings.

Efficacy of Integrating Cervical Posture Correction With Lumbar Stabilization Exercises for Mechanical Low Back Pain: A Randomized Blinded Clinical Trial

Although current lumbar stabilization exercises are beneficial for chronic mechanical low back pain, further research is recommended focusing on global spinal alignment normalization. This randomized, controlled, blinded trial was conducted to determine the effects of adding cervical posture correction to lumber stabilization on chronic mechanical low back pain. Fifty adult patients (24 males) with chronic mechanical low back pain and forward head posture received 12 weeks treatment of either both programs (group A) or lumbar stabilization (group B). The primary outcome was back pain. The secondary outcomes included the craniovertebral angle, Oswestry Disability Index, C7-S1 sagittal vertical axis, and sagittal intervertebral movements. The multivariate analysis of variance indicated a significant group-by-time interaction (P = .001, partial η2 = .609). Pain, disability, C7-S1 sagittal vertical axis, and l2-l3 intervertebral rotation were reduced in group A more than B (P = .008, .001, .025, and .001). Craniovertebral angle was increased in A when compared to B (P = .001). However, there were no significant group-by-time interactions for other intervertebral movements. Within-group comparisons were significant for all outcomes except for craniovertebral angle within patients in the control group. Adding cervical posture correction with lumber stabilization for management of chronic low back pain seemed to have better effects than the application of a stabilization program only.

Effectiveness of basic body awareness therapy in adolescents with idiopathic scoliosis: A randomized controlled study1

BACKGROUND

In scoliosis, curve progresses due to muscle imbalance and poor posture. Basic body awareness therapy (BBAT) aims to improve posture, coordination, and balance by increasing body awareness, which may help decrease deformities.

OBJECTIVE

This study aimed to investigate effects of Basic body awareness therapy (BBAT) on curve magnitude, trunk asymmetry, cosmetic deformity, and quality of life in adolescent idiopathic scoliosis (AIS) patients.

METHODS

Twenty female AIS patients were randomly assigned to BBAT and traditional exercises (TEs) groups. The BBAT group received BBAT and traditional exercises (TEs), while the TEs group received only TEs. The following assessments were included: Cobb angles using X-ray, angle of trunk rotation (ATR) using scoliometer, trunk asymmetry using the Posterior Trunk Symmetry Index (POTSI), cosmetic deformity using the Walter Reed Visual Assessment Scale (WRVAS), and quality of life using the SRS-22 test. Measurements were conducted at baseline examination and ten weeks later. Patients were instructed to wear their brace 23 h daily. Results were analyzed using the Wilcoxon rank-sum test to compare repeated measurements and Mann-Whitney U test to compare the groups.

RESULTS

The BBAT group had greater improvement in the thoracic Cobb angle than the TEs group. Cosmetic deformity improved in both groups, whereas body asymmetry improved in only the BBAT group. SRS-22 scores were unchanged in both groups.

CONCLUSIONS

BBAT as an additive to bracing and TEs improve curve magnitude, body symmetry and trunk deformity.

Does improvement towards a normal cervical sagittal configuration aid in the management of cervical myofascial pain syndrome: a 1- year randomized controlled trial

Background

There is a growing interest concerning the understanding of and rehabilitation of the sagittal configuration of the cervical spine as a clinical outcome. However, the literature on the topic specific to conservative treatment outcomes of patients with chronic myofascial cervical pain syndrome (CMCPS) has not adequately addressed the relationship between cervical sagittal alignment and improved pain, disability and range of motion.

Methods

A randomized controlled study with a 1-year follow-up. Here, 120 (76 males) patients with chronic CMCPS and defined cervical sagittal posture abnormalities were randomly assigned to the control or an intervention group. Both groups received the Integrated neuromuscular inhibition technique (INIT); additionally, the intervention group received the denneroll cervical traction device. Alignment outcomes included two measures of sagittal posture: cervical angle (CV), and shoulder angle (SH). Patient relevant outcome measures included: neck pain intensity (NRS), neck disability (NDI), pressure pain thresholds (PPT), cervical range of motion using the CROM. Measures were assessed at three intervals: baseline, 10 weeks, and 1 year after the 10 week follow up.

Results

After 10 weeks of treatment, between group statistical analysis, showed equal improvements for both the intervention and control groups in NRS (p = 0.36) and NDI (p = 0.09). However, at 10 weeks, there were significant differences between groups favoring the intervention group for PPT (p<0.001) and all measures of CROM (p<0.001). Additionally, at 10 weeks the sagittal alignment variables showed significant differences favoring the intervention group for CV p<0.001 and SH (p<0.001) indicating improved CSA. Importantly, at the 1-year follow-up, between group analysis identified a regression back to baseline values for the control group for the non-significant group differences (NRS and NDI) at the 10-week mark. Thus, all variables were significantly different between groups favoring the intervention group at 1-year follow up: NRS (p<0.001), NDI (p<0.001), PPT p<0.001), CROM (p<0.001), CV (p<0.001), SH (p<0.001).

Conclusion

The addition of the denneroll cervical orthotic to a multimodal program positively affected CMCPS outcomes at long term follow up. We speculate the improved sagittal cervical posture alignment outcomes contributed to our findings.

Effects of Kinesio taping and exercise on forward head posture

BACKGROUND

Little is known about the effects of Kinesio taping and therapeutic exercise on correcting forward head posture.

OBJECTIVE

To compare Kinesio taping versus therapeutic exercise for forward head posture on static posture, dynamic mobility and functional outcomes.

METHODS

Sixty subjects (31 women, 29 men) with forward head postures participated in this study. They were randomly assigned to either one of the three groups: (1) exercise group (n = 20), (2) taping group (n = 20), and (3) control groups (n = 20). The horizontal forward displacement (HFD) between ear lobe and acromion process, upper cervical and lower cervical angle (UCA, LCA), active range of motion (AROM) of cervical spine, and neck disability index (NDI) were measured before and after a 5-week intervention, and a 2-week follow-up. Data were analyzed by means of a mixed design repeated-measures ANOVA.

RESULTS

Both taping and exercise groups showed significant improvements in HFD compared with the control group at post-treatment and follow-up. Compared with the control group, the exercise group exhibited significant improvements in the LCA and the side bending AROM at post-treatment.

CONCLUSIONS

Both Kinesio taping and therapeutic exercise improve forward head posture after intervention and a 2-week follow-up. The effectiveness of therapeutic exercise is better than taping.

2016 SOSORT guidelines: orthopaedic and rehabilitation treatment of idiopathic scoliosis during growth

BACKGROUND

The International Scientific Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) produced its first guidelines in 2005 and renewed them in 2011. Recently published high-quality clinical trials on the effect of conservative treatment approaches (braces and exercises) for idiopathic scoliosis prompted us to update the last guidelines' version. The objective was to align the guidelines with the new scientific evidence to assure faster knowledge transfer into clinical practice of conservative treatment for idiopathic scoliosis (CTIS).

METHODS

Physicians, researchers and allied health practitioners working in the area of CTIS were involved in the development of the 2016 guidelines. Multiple literature reviews reviewing the evidence on CTIS (assessment, bracing, physiotherapy, physiotherapeutic scoliosis-specific exercises (PSSE) and other CTIS) were conducted. Documents, recommendations and practical approach flow charts were developed using a Delphi procedure. The process was completed with the Consensus Session held during the first combined SOSORT/IRSSD Meeting held in Banff, Canada, in May 2016.

RESULTS

The contents of the new 2016 guidelines include the following: background on idiopathic scoliosis, description of CTIS approaches for various populations with flow-charts for clinical practice, as well as literature reviews and recommendations on assessment, bracing, PSSE and other CTIS. The present guidelines include a total of 68 recommendations divided into following topics: bracing (n = 25), PSSE to prevent scoliosis progression during growth (n = 12), PSSE during brace treatment and surgical therapy (n = 6), other conservative treatments (n = 2), respiratory function and exercises (n = 3), general sport activities (n = 6); and assessment (n = 14). According to the agreed strength and level of evidence rating scale, there were 2 recommendations on bracing and 1 recommendation on PSSE that reached level of recommendation "I" and level of evidence "II". Three recommendations reached strength of recommendation A based on the level of evidence I (2 for bracing and one for assessment); 39 recommendations reached strength of recommendation B (20 for bracing, 13 for PSSE, and 6 for assessment).The number of paper for each level of evidence for each treatment is shown in Table 8.

CONCLUSION

The 2016 SOSORT guidelines were developed based on the current evidence on CTIS. Over the last 5 years, high-quality evidence has started to emerge, particularly in the areas of efficacy of bracing (one large multicentre trial) and PSSE (three single-centre randomized controlled trials). Several grade A recommendations were presented. Despite the growing high-quality evidence, the heterogeneity of the study protocols limits generalizability of the recommendations. There is a need for standardization of research methods of conservative treatment effectiveness, as recognized by SOSORT and the Scoliosis Research Society (SRS) non-operative management Committee.

Spinal Manipulative Therapy for Adolescent Idiopathic Scoliosis: A Systematic Review

OBJECTIVE

The purpose of this study was to perform a systematic review of clinical trials of spinal manipulative therapy for adolescent idiopathic scoliosis.

METHODS

Search strategies were developed for PubMed, CINHAL, and CENTRAL databases. Studies were included through June 2016 if they were prospective trials that evaluated spinal manipulative therapy (eg, chiropractic, osteopathic, physical therapy) for adolescent idiopathic scoliosis. Data were extracted and assessed by 2 independent reviewers. Cochrane risk of bias tools were used to assess the quality of the included studies. Data were reported qualitatively because heterogeneity prevented statistical pooling.

RESULTS

Four studies satisfied the inclusion criteria and were critically appraised. The findings of the included studies indicated that spinal manipulative therapy might be effective for preventing curve progression or reducing Cobb angle. However, the lack of controls and small sample sizes precluded robust estimation of the interventions' effect sizes.

CONCLUSION

There is currently insufficient evidence to establish whether spinal manipulative therapy may be beneficial for adolescent idiopathic scoliosis. The results of the included studies suggest that spinal manipulative therapy may be a promising treatment, but these studies were all at substantial risk of bias. Further high-quality studies are warranted to conclusively determine if spinal manipulative therapy may be effective in the management of adolescent idiopathic scoliosis.

Non-invasive interventions in idiopathic scoliosis: a systematic review

Abstract Introduction: Idiopathic Scoliosis (IS) is an idiopathic curvature of the spine in all three plans, been treated conservatively (non-invasive) or surgicaly (invasive). The effectiveness of noninvasive therapy still remains lacking in a scientific basis to support their evidence-based applicability. Objective: Evaluate the effects of non-invasive interventions in spine lateral inclination in IS through a systematic literature review. Methods: The search of studies in MEDLINE, SCOPUS and COCHRANE databases was performed on 24th March, 2014. The terms used were: Scoliosis, therapeutic exercise, physical therapy. Clinical trials with scoliotic patients undergoing some type of non-invasive intervention were included. The outcome was spine lateral inclination. Results: The research found 941 studies, seven of these were included after a screening performed by two independent reviewers. Six studies (85.7%) have adopted some sort of kinesiotherapeutic technic, and three studies (42.8%) used corrective orthosis. The average intervention time in kinesiotherapeutic technique studies was of 37.6 weeks and 91.6 weeks in the studies of corrective brace. The progression improvement of the spine lateral inclination was reported by 83.3% (5 of 6) of the kinesiotherapeutic technique studies and in 66.6% (2 of 3) of studies with corrective brace. Conclusion: An improvement was found, in general, in the progression of spine lateral inclination in IS subjects of both sexes from 11 to 25 years of age undergoing non-invasive interventions.

Active Treatment for Idiopathic Adolescent Scoliosis (ACTIvATeS): a feasibility study

BACKGROUND

The feasibility of conducting a definitive randomised controlled trial (RCT) evaluating the clinical effectiveness and cost-effectiveness of scoliosis-specific exercises (SSEs) for adolescent idiopathic scoliosis (AIS) is uncertain.

OBJECTIVES

The aim of this study was to assess the feasibility of conducting a large, multicentre trial of SSE treatment for patients with AIS, in comparison with standard care, and to refine elements of the study design. The objectives were to (1) update a systematic review of controlled trials evaluating the efficacy of SSE in AIS; (2) survey UK orthopaedic surgeons and physiotherapists to determine current practice, patient populations and equipoise; (3) randomise 50 adolescents to a feasibility trial of either usual care or SSE interventions across a range of sites; (4) develop, document and assess acceptability and adherence of interventions; (5) assess and describe training requirements of physiotherapists; and (6) gain user input in all relevant stages of treatment and protocol design.

DESIGN

Multicomponent feasibility study including UK clinician survey, systematic literature review and a randomised feasibility trial.

SETTING

The randomised feasibility study involved four secondary care NHS trusts providing specialist care for patients with AIS.

PARTICIPANTS

The randomised feasibility study recruited people aged 10-16 years with mild AIS (Cobb angle of < 50°).

INTERVENTIONS

The randomised study allocated participants to standard practice of advice and education or a physiotherapy SSE programme supported by a home exercise plan. Our choice of intervention was informed by a systematic review of exercise interventions for AIS.

MAIN OUTCOME MEASURES

The main outcome was feasibility of recruitment to the randomised study. Other elements were to inform choice of outcomes for a definitive trial and included curve severity, quality of life, requirement for surgery/brace, adverse events, psychological symptoms, costs and health utilities.

RESULTS

A UK survey of orthopaedic consultants and physiotherapists indicated a wide variation in current provision of exercise therapy through physiotherapy services. It also found that clinicians from at least 15 centres would be willing to have their patients involved in a full study. A systematic review update found five new studies that were generally of low quality but showed some promise of effectiveness of SSE. The randomised study recruited 58 patients from four NHS trusts over 11 months and exceeded the pre-specified target recruitment rate of 1.4 participants per centre per month, with acceptable 6-month follow-up (currently 73%). Adherence to treatment was variable (56% of participants completed treatment offered). The qualitative study found the exercise programme to be highly acceptable. We learnt important lessons from patient and public involvement during the study in terms of study and intervention presentation, as well as practical elements such as scheduling of intervention sessions.

CONCLUSIONS

A definitive RCT evaluating clinical effectiveness and cost-effectiveness of SSE for idiopathic scoliosis is warranted and feasible. Such a RCT is a priority for future work in the area. There is a sufficiently large patient base, combined with willingness to be randomised within specialist UK centres. Interventions developed during the feasibility study were acceptable to patients, families and physiotherapists and can be given within the affordability envelope of current levels of physiotherapy commissioning.

MUSCLE DISORDERS IN ADOLESCENT IDIOPATHIC SCOLIOSIS: LITERATURE REVIEW

ABSTRACT Scoliosis is characterized by three-dimensional changes of the spine and is estimated to be present in 4% of the population worldwide. The most common form is the adolescent idiopathic. The purpose of this study is to identify the major muscle abnormalities found in patients with adolescent idiopathic scoliosis through a literature review. We conducted an electronic search of the national databases PubMed, Lilacs, PEDro, and EMBASE using the keywords "scoliosis", "biomechanics", "exercise", "physical therapy specialty", "idiopathic", and "muscles", from January 2003 to April 2015. The most relevant articles in English, Portuguese and Spanish were selected by title and abstract. It was also performed a manual search of the references of the selected articles. From a total of 4,319 articles, 11 were selected. We conclude that individuals with AIS have changes in the paraspinal muscles, with a difference in activation between the concave and convex sides, suggesting an increase in EMG activity on the convex side, although there is still no consensus among the authors.

Correlation between Trunk Posture and Neck Reposition Sense among Subjects with Forward Head Neck Postures

Objective. To assess the correlation of abnormal trunk postures and reposition sense of subjects with forward head neck posture (FHP). Methods. In all, postures of 41 subjects were evaluated and the FHP and trunk posture including shoulder, scapular level, pelvic side, and anterior tilting degrees were analyzed. We used the head repositioning accuracy (HRA) test to evaluate neck position senses of neck flexion, neck extension, neck right and left side flexion, and neck right and left rotation and calculated the root mean square error in trials for each subject. Spearman's rank correlation coefficients and regression analysis were used to assess the degree of correlation between the trunk posture and HRA value, and a significance level of α = 0.05 was considered. Results. There were significant correlations between the HRA value of right side neck flexion and pelvic side tilt angle (p < 0.05). If pelvic side tilting angle increases by 1 degree, right side neck flexion increased by 0.76 degrees (p = 0.026). However, there were no significant correlations between other neck motions and trunk postures. Conclusion. Verifying pelvic postures should be prioritized when movement is limited due to the vitiation of the proprioceptive sense of neck caused by FHP.

Effects of Exercise on Spinal Deformities and Quality of Life in Patients with Adolescent Idiopathic Scoliosis

OBJECTIVES

This systematic review was conducted to examine the effects of exercise on spinal deformities and quality of life in patients with adolescent idiopathic scoliosis (AIS).

DATA SOURCES

Electronic databases, including PubMed, CINAHL, Embase, Scopus, Cochrane Register of Controlled Trials, PEDro, and Web of Science, were searched for research articles published from the earliest available dates up to May 31, 2015, using the key words "exercise," "postural correction," "posture," "postural curve," "Cobb's angle," "quality of life," and "spinal deformities," combined with the Medical Subject Heading "scoliosis."

STUDY SELECTION

This systematic review was restricted to randomized and nonrandomized controlled trials on AIS published in English language. The quality of selected studies was assessed by the PEDro scale, the Cochrane Collaboration's tool, and the Grading of Recommendations Assessment, Development, and Evaluation System (GRADE).

DATA EXTRACTION

Descriptive data were collected from each study. The outcome measures of interest were Cobb angle, trunk rotation, thoracic kyphosis, lumbar kyphosis, vertebral rotation, and quality of life.

DATA SYNTHESIS

A total of 30 studies were assessed for eligibility. Six of the 9 selected studies reached high methodological quality on the PEDro scale. Meta-analysis revealed moderate-quality evidence that exercise interventions reduce the Cobb angle, angle of trunk rotation, thoracic kyphosis, and lumbar lordosis and low-quality evidence that exercise interventions reduce average lateral deviation. Meta-analysis revealed moderate-quality evidence that exercise interventions improve the quality of life.

CONCLUSIONS

A supervised exercise program was superior to controls in reducing spinal deformities and improving the quality of life in patients with AIS.

The effects of horse-riding simulator exercise and Kendall exercise on the forward head posture

[Purpose] The aim of this study was to examine the effects of horse-riding simulator exercise and Kendall exercise on forward head posture. [Subjects and Methods] Thirty elderly college students with a forward head posture were randomly divided into two groups for 15 persons each, a horse-riding simulator group and Kendall exercise group, and performed exercise for eight weeks. [Results] The horse-riding simulator group and Kendall exercise group showed significant differences after the intervention in New York state posture rating, craniovertebral angle, and cranial rotation angle. The horse-riding simulator group showed a significantly smaller value than the Kendall exercise group for New York state posture rating evaluation after the intervention. [Conclusion] The results of this study indicate that horse-riding simulator exercise is more effective on forward head posture than Kendall exercise. Therefore, horse-riding simulator exercise can be used as a new simple treatment method for the ever-growing forward head posture.

The effect of adding forward head posture corrective exercises in the management of lumbosacral radiculopathy: a randomized controlled study

OBJECTIVE

The purpose of this study was to determine the immediate and long-term effects of a multimodal program, with the addition of forward head posture correction, in patients with chronic discogenic lumbosacral radiculopathy.

METHODS

This randomized clinical study included 154 adult patients (54 females) who experienced chronic discogenic lumbosacral radiculopathy and had forward head posture. One group received a functional restoration program, and the experimental group received forward head posture corrective exercises. Primary outcomes were the Oswestry Disability Index (ODI). Secondary outcomes included the anterior head translation, lumbar lordosis, thoracic kyphosis, trunk inclination, lateral deviation, trunk imbalance, surface rotation, pelvic inclination, leg and back pain scores, and H-reflex latency and amplitude. Patients were assessed at 3 intervals (pretreatment, 10-week posttreatment, and 2-year follow-up).

RESULTS

A general linear model with repeated measures indicated a significant group × time effect in favor of the experimental group on the measures of ODI (F = 89.7; P < .0005), anterior head translation (F = 23.6; P < .0005), H-reflex amplitude (F = 151.4; P < .0005), H-reflex latency (F = 99.2; P < .0005), back pain (F = 140.8; P < .0005), and leg pain (F = 72; P < .0005). After 10 weeks, the results revealed an insignificant difference between the groups for ODI (P = .08), back pain (P = .29), leg pain (P = .019), H-reflex amplitude (P = .09), and H-reflex latency (P = .098). At the 2-year follow-up, there were significant differences between the groups for all variables adopted for this study (P < .05).

CONCLUSIONS

The addition of forward head posture correction to a functional restoration program seemed to positively affect disability, 3-dimensional spinal posture parameters, back and leg pain, and S1 nerve root function of patients with chronic discogenic lumbosacral radiculopathy.
