Upper thoracic spine mobilization and mobility exercise versus upper cervical spine mobilization and stabilization exercise in individuals with forward head posture: a randomized clinical trial

Effects of spinal mobilization on physical function in patients with stroke: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to identify, critically appraise, and synthesize current evidence regarding the effects of spinal mobilization on physical function in patients with stroke. Three databases, PubMed, Embase, and Scopus, were searched from inception to March 15, 2024. Randomized controlled trials comparing the effects of spinal mobilization to conventional therapy were eligible for inclusion. Methodological quality was assessed using the Physiotherapy Evidence Database scale. Meta-analyses were performed to determine the effects of spinal mobilization. Nine randomized controlled trials were included, with a total of 294 patients with stroke. All included studies were evaluated as good or above for quality assessment. No adverse events related to spinal mobilization were reported. Compared to conventional therapy, spinal mobilization demonstrated significantly improved forward head posture (SMD: 1.00, 95% CI: 0.53 to 1.46, p < 0.001); there were no between-group differences on forced vital capacity (SMD: 0.44, 95% CI: -0.01 to 0.88, p = 0.06), forced expiratory volume (SMD: 0.33, 95% CI: -0.12 to 0.77, p = 0.15), balance (SMD: 0.36, 95% CI: -0.04 to 0.77, p = 0.08), gait speed (SMD: 0.48, 95% CI: -0.44 to 1.40, p = 0.31), and trunk function (SMD: 0.79, 95% CI: -0.17 to 1.75, p = 0.11). Cervical mobilization significantly improved forward head posture; however, no significant differences were found in other outcomes. Clinicians may consider spinal mobilization as an adjunctive intervention in stroke rehabilitation to address posture-related impairments to expand treatment strategy and optimize quality of care.

Immediate effects of visuomotor tracking with the head on cervical sensorimotor function and pain in chronic neck pain patients

BACKGROUND

Working in awkward and sustained postures is, besides psychosocial risk factors, the most reported physical risk factor for neck pain. Accurate proprioception is fundamental to correcting awkward head-to-trunk positions, but impaired proprioceptive performance has been found in patients with chronic neck pain.

OBJECTIVE

The aim was to compare the effectiveness of two different interventions in a workplace set-up on sensorimotor performance and pain sensitivity in people with chronic neck pain.

METHODS

A total of 25 patients with chronic neck pain participated in this double-blind study. Patients were randomly allocated to the visuomotor tracking task group or the video group (watching a massage video, imagining themselves being massaged). The primary outcomes were cervical joint position sense acuity and pressure pain threshold of the cervical spine, evaluated by a blinded assessor.

RESULTS

There were significant time by group interactions for cervical joint position sense acuity (F1;23: 4.38; p= 0.048) and pressure pain threshold (F1;23: 5.78; p= 0.025), with the tracking task group being more accurate in cervical joint position sense testing and less pain sensitive for pressure pain threshold.

CONCLUSIONS

The visuomotor tracking task improves cervical joint position sense acuity and reduces pressure pain threshold immediately after intervention in people with chronic neck pain.

Efficacy of scapulothoracic exercises on proprioception and postural stability in cranio-cervico-mandibular malalignment: A randomized, double-blind, controlled trial

BACKGROUND

Cranio-cervico-mandibular (CCM) malalignment is associated with forward head posture (FHP) and temporomandibular joint (TMJ) disorders and affects masticatory muscles.

OBJECTIVE

This randomized, double-blind controlled trial aimed to compare the efficacy of scapula-thoracic (ST) exercises on temporomandibular and cervical joint position sense and postural stability in individuals with CCM malalignment.

METHODS

Fourty-nine participants with CCM malalignment were randomly assigned to the ST exercise group (STEG, n= 24) or the control group (CG, n= 25). STEG included progressive strengthening, proprioceptive, and stabilization exercises. All participants were assessed before treatment, at the end of the 8th week treatment period and at the 12th week post-treatment follow-up. Cranio-vertebral angle measurement, Fonseca's Questionnaire, Helkimo Clinical Dysfunction Index, TMJ position test, cervical joint position error test and postural stability assessment were used.

RESULTS

The TMJ and cervical joint position sense, total sway degree, area gap percentage, sway velocity and antero-posterior body sway results showed significant improvement in the STEG compared to the CG (p< 0.05), however medio-lateral body sway did not differ between groups (p> 0.05).

CONCLUSIONS

Postural stability, TMJ and cervical joint position sense appear to be affected in individuals with CCM malalignment. Our results showed that an exercise program including ST stabilization, proprioception and strengthening of the scapular muscles may be effective in the management of CCM malalignment and will allow clinicians to plan holistic treatment.

Evaluation of forward head posture and thoracic kyphosis in migraine

BACKGROUND

The purpose of the current study was to investigate the forward head posture (FHP), thoracic kyphosis and their relationships between individuals with migraine and healthy controls using the DIERS Formetric 4D motion imaging system.

METHODS

In this observational case-control study, a total of 39 migraine patients and 44 healthy subjects were enrolled. FHP and thoracic kyphosis were assessed by using the 4D Formetric DIERS system. The visual analogue scale (VAS) and Neck Disability Index (NDI) was used to evaluate neck pain and neck disability. Headache status were evaluated through Migraine Disability Assessment (MIDAS) and Numeric Pain Rating Scale (NPRS) questionnaires.

RESULTS

The fleche cervicale (57.72 ± 13.72 mm vs. 40.00 ± 4.75 mm; p < 0.001) and kyphotic angle (57.39 ± 8.76° vs. 38.21 ± 5.67°; p < 0.001) were significantly higher in patients with migraine compared to control group. When NDI categories were compared, the migraine group showed significantly increase in the number of patients with moderate or severe disability (p < 0.001). A positive correlation was found between fleche cervicale and thoracic kyphosis (r = 0.71, p < 0.001).

CONCLUSIONS

This study revealed that patients with migraine exhibited a greater FHP and thoracic kyphosis compared to the control group. A 3-dimensional objective measurement may be a reliable diagnostic tool to evaluate posture analysis in clinical practice in the future.

Do cervical stabilization exercises change the effects of conventional exercises in patients with Parkinson's disease?

OBJECTIVES

The aim of this study was to examine whether cervical stabilization exercises (CSEs) change the effects of conventional exercises (CEs) in patients with PD.

METHODS

Twenty-five patients with PD were randomized into two groups. While the experimental group (EG) received CSEs in addition to CEs, the control group (CG) received only CEs. Both programs lasted 8 weeks. Eighteen participants were able to complete the study. The outcomes were the changes in posture, cervical joint position sense (JPS), balance assessment, 10-m walking tests (10MWT), and the Timed Up & Go (TUG) test.

RESULTS

At the end of the study, significant improvement was observed in both groups in terms of trunk rotation angle and pelvic asymmetry, the time parameter of TUG, and the 10MWT (p < 0.05). In the EG, greater improvement was detected in the Berg Balance Scale, static posturography, postural alignment, JPS, and the cadence parameter of TUG (p < 0.05).

DISCUSSION

CEs and CSEs could improve walking speed and posture in patients with PD, but if CSEs are added to CEs, greater improvements could be achieved in JPS and postural control.(Clinical Trials ID: NCT03854747).

Treatment of Chronic Neck Pain in Patients with Forward Head Posture: A Systematic Narrative Review

(1) Background: Forward head posture (FHP) is one of the most common cervical postural deviations and is characterized by head protrusion or forward head placement in relation to the shoulder in the sagittal plane. Patients with FHP often experience neck pain and disability. The aim of this study was to investigate whether treatment programs are effective in the management of neck pain in patients with FHP. (2) Methods: A MEDLINE (PubMed), Embase, Cochrane Library, and Scopus database search was conducted for English language articles on patients with chronic neck pain and FHP published until 12 April 2023. To identify potentially relevant articles, the following key search phrases were combined: 'forward head posture' and 'pain'. After searching, 2516 potentially relevant articles were identified. After reading the titles and abstracts and assessing their eligibility based on full-text articles, 16 articles were included in this review. (3) Results: Among the 16 studies that investigated the efficacy of treatment programs for managing chronic pain in patients with FHP, 11 investigated the effect of exercise programs, and 5 investigated the effect of manual therapy. Patients reported significant improvement in pain and disability after receiving treatment programs such as corrective postural exercises and special manual therapy techniques. (4) Conclusions: Various treatment programs, including postural corrective exercises and manual therapy, are beneficial for improving pain and disability in patients with FHP.

A Multidisciplinary Approach to Swallowing Rehabilitation in Patients with Forward Head Posture

(1) Background and Objectives: The forward head posture (FHP) is characterized by increased extensions of upper cervical vertebrae and flexion of the lower cervical vertebrae and upper thoracic regions, associated with muscle shortening. The compressive loading on the tissues in the cervical spine negatively impacts suprahyoid and infrahyoid muscles and generates increased tension of the masticatory muscles. The tongue has relations with the suprahyoid and the infrahyoid muscles. The pattern of swallowing evolves gradually from birth to the age of four. If this developmental transition does not occur, the result is persistent infantile or atypical swallowing-an orofacial myofunctional disorder with the tongue in improper position during swallowing, causing strain and stress on the jaw, face, head and neck. In FHP, muscles crucial to swallowing are biomechanically misaligned. The lengthening of the suprahyoid muscles necessitates stronger contractions to achieve proper hyolaryngeal movement during swallowing. This study assesses the added benefits of physiotherapy to the traditional myofunctional swallowing rehabilitation for patients with FHP. The underlying hypothesis is that without addressing FHP, swallowing rehabilitation remains challenged and potentially incomplete. (2) Materials and Methods: A total of 61 participants (12-26 years) meeting the inclusion criteria (FHP and atypical swallowing) were divided into two similar groups. Group A attended one orofacial myofunctional therapy (OMT) and one physiotherapy session per week, group B only one OMT session per week, for 20 weeks. Exclusion criteria were as follows: ankyloglossia, neurological impairment affecting tongue and swallowing, cervical osteoarticular pathology, other previous or ongoing treatments for FHP and atypical swallowing. (3) Results: There is a significant improvement in terms of movement and use of the orofacial structures (tongue, lips, cheeks), as well as in breathing and swallowing in both groups. Group A achieved better outcomes as the CVA angle was directly addressed by manual therapy and GPR techniques. (4) Conclusions: The combined therapy proved to be more effective than single OMT therapy.

An Exercise Prescription To Improve Posture, Minimize Injury, and Improve Career Longevity in Surgeons

A contemporary exercise and strength regimen can improve posture, minimize injury, and improve career longevity in surgeons. By targeting core stability, neck posture, and thoracoscapular strength, surgeons and operating room teams can minimize neck and lower back pain.

The association between forward head posture and masticatory muscle pressure pain thresholds in patients with temporomandibular joint dissorders: a cross-sectional observational study

OBJECTIVES

Forward head posture (FHP) is common in patients with temporomandibular joint disorders (TMDs); however, whether it contributes to TMD symptoms remains unclear. The aim of this study was to investigate the association between (1) FHP and masticatory muscle pressure pain thresholds (PPTs) and (2) neck muscle and masticatory muscle PPTs.

MATERIALS AND METHODS

A total of 145 patients diagnosed with TMD were recruited between December 2020 and April 2021. Data regarding FHP and neck and masticatory muscle PPTs were collected. FHP was characterized by the craniocervical angle (CVA) measured between the horizontal line through C7 and the line between the tragus of the ear and C7. Patients were divided into either the FHP group (CVA ≤ 51°) or the non-FHP group. Differences in the masseter and temporalis muscle PPTs between the two groups were analyzed using the Mann-Whitney U test. The correlation between the CVA, neck, and masticatory muscle PPTs in all patients was determined by Spearman's correlation analysis.

RESULTS

There were 70 patients in the FHP group and 75 patients in the non-FHP group. No significant difference in masseter and temporalis muscle PPTs was found between the two groups (p > 0.05). No correlation was found between FHP and masticatory muscle PPTs (p > 0.05). A significant association was found between the neck muscle and masticatory muscle PPTs (p < 0.05). The C5-C6 pillar and masticatory PPTs were either moderately (r = 0.435, masseter muscle) or strongly (r = 0.608, temporalis muscle) correlated, while the correlation between the trapezius and masticatory muscles was moderate (r = 0.378, masseter muscle and r = 0.461, temporalis muscle).

CONCLUSION

FHP was not directly associated with masticatory muscle PPTs. Masticatory muscle PPTs were strongly or moderately associated with neck muscle PPTs. Therefore, the presence of neck pain, not the degree of FHP, in patients with TMD is of significance.

CLINICAL RELEVANCE

In TMD treatment, we should pay attention to and actively relieve neck pain.

Effectiveness of motor control exercises versus other musculoskeletal therapies in patients with pelvic girdle pain of sacroiliac joint origin: A systematic review with meta-analysis of randomized controlled trials

BACKGROUND

Pelvic girdle pain represents a group of musculoskeletal pain disorders associated with the sacroiliac joint and/or the surrounding musculoskeletal and ligamentous structures. Its physical management is still a serious challenge as it has been considered the primary cause of low back pain.

OBJECTIVE

This review sought to determine the effectiveness of motor control exercises for two clinically relevant measures; i.e., pain and disability, on patients with pelvic girdle pain of sacroiliac joint origin.

METHODS

This review covered only randomized controlled studies. Online databases, such as PubMed, Embase, Scopus, and Cochrane Library, were searched from January 1, 1990, to December 31, 2019. PEDro scale was used to assess the methodological quality of included studies, while Review Manager was employed to synthesize data in view of meta-analysis. The PRISMA guidelines were applied for this review.

RESULTS

Twelve randomized controlled trials of moderate-to-high quality were included in this review. The studies involved 1407 patients with a mean age ranging from 25.5 to 42.1 years as well as intervention and follow-up durations from 1 week to 2 years. Motor control exercises alone for pelvic girdle pain of sacroiliac joint origin were not effective in terms of pain reduction (SMD = 0.29 [-0.64,1.22]) compared to control interventions whereas they were slightly effective in terms of disability reduction (SMD =-0.07 [-0.67, 0.53]) at short-term. The combination of motor control exercises with other musculoskeletal therapies, however, revealed to be more effective than control interventions in terms of pain reduction (SMD =-1.78 [-2.49, -1.07]; 95%CI) and lessened disability (SMD =-1.80 [-3.03, -0.56]; 95%CI) at short-term.

CONCLUSION

Motor control exercises alone were not found to be effective in reducing pain at short-term. However, their combination with other musculoskeletal therapies revealed a significant and clinically-relevant decrease in pain and disability at short-term, especially in peripartum period.

Effect of improved thoracic kyphosis on forward shoulder posture after mobilization in individuals with thoracic hyperkyphosis

BACKGROUND

Thoracic hyperkyphosis structurally alters the position of the scapula to cause forward shoulder posture. However, the effect of improved thoracic hyperkyphosis on forward shoulder posture is unclear. The objective of this study was to determine the effect of eight weeks of thoracic mobilization on improving thoracic hyperkyphosis and forward shoulder posture and determine the cutoff change ratio in kyphosis for improving forward shoulder posture using the decision tree method.

METHOD

This study included 19 participants with thoracic hyperkyphosis who underwent thoracic mobilization for eight weeks. Forward shoulder posture (acromion-to-the-wall index) and thoracic kyphosis were measured before and after thoracic mobilization.

FINDINGS

The intervention significantly improved thoracic kyphosis and forward shoulder posture. The cutoff change ratio in kyphosis for improving forward shoulder posture was >13.79%. In the subgroup analysis of participants with a change ratio of kyphosis >13.79% (seven cases), all patients showed improved forward shoulder posture. In contrast, in the subgroup with a change ratio of kyphosis ≤13.79% (12 cases), eight cases showed improved forward shoulder posture, while four cases showed no improvement.

INTERPRETATION

Thoracic mobilization can be recommended in shoulder rehabilitation programs to improve forward shoulder posture to manage and prevent scapular malalignment in individuals with thoracic hyperkyphosis. We suggest that a high probability of improvement in forward shoulder posture can be expected when kyphosis is improved by >13.79%.

Effect of pompage on pain, disability and craniocervical position of female teachers - Randomized clinical trial

Abstract Introduction: Education professionals are one of the most important occupational groups and represents one of the main parts of the economy of modern society. The vocal demands most mentioned by the teachers are talking while standing up, talking a lot and in a closed environment, which corresponds to the most frequent situations encountered in teaching. In addition, remaining in the standing position for a prolonged period may have repercussions on other systems and generate postural deviations, pain and reduced functionality. Objective: To verify changes in pressure pain threshold, in disability index and in craniocervical posture of female teachers with vocal and musculoskeletal complaints, and with normal larynx, after myofascial release - pompage. Methods: This study was a controlled and randomized clinical trial. The following procedures were performed: anamnesis, videolaryngoscopy, hearing screening, clinical and photogrammetric postural assessment using the SAPo® protocol, completion of the neck pain self-assessment protocol Neck Disability Index, and pain threshold in the cervical muscles using the Pain Pressure Threshold. Myofascial therapy with pompage had a total of 24 sessions of 40 min each, three times a week, in 28 teachers assigned to the study group (SG), and 28 to the control group (CG). Afterwards, the groups were reassessed. Results: The SG presented a significant improvement in the pain threshold of all the muscles evaluated, in the posture of most of the body segments evaluated, and in the cervical disability. In the CG there was a significant improvement in angle A2 after therapy. Conclusion: After myofascial release therapy with pompage, the subjects presented a reduction in cervical pain and in functional disability, an increase in pain threshold, and posture improvement.

Comparison of an exercise program with and without manual therapy for patients with chronic neck pain and upper cervical rotation restriction. Randomized controlled trial

Background

Cervical exercise has been shown to be an effective treatment for neck pain, but there is still a need for more clinical trials evaluating the effectiveness of adding manual therapy to the exercise approach. There is a lack of evidence on the effect of these techniques in patients with neck pain and upper cervical rotation restriction.

Purpose

To compare the effectiveness of adding manual therapy to a cervical exercise protocol for the treatment of patients with chronic neck pain and upper cervical rotation restriction.

Methods

Single-blind randomized clinical trial. Fifty-eight subjects: 29 for the Manual Therapy+Exercise (MT+Exercise) Group and 29 for the Exercise group. Neck disability index, pain intensity (0–10), pressure pain threshold (kPa), flexion-rotation test (°), and cervical range of motion (°) were measured at the beginning and at the end of the intervention, and at 3-and 6-month follow-ups. The MT+Exercise Group received one 20-min session of manual therapy and exercise once a week for 4 weeks and home exercise. The Exercise Group received one 20-min session of exercise once a week for 4 weeks and home exercise.

Results

The MT+Exercise Group showed significant better values post-intervention in all variables: neck disability index: 0% patient with moderate, severe, or complete disability compared to 31% in the Exercise Group (p = 0.000) at 6-months; flexion-rotation test (p = 0.000) and pain intensity (p = 0.000) from the first follow-up to the end of the study; cervical flexion (p = 0.002), extension (p = 0.002), right lateral-flexion (p = 0.000), left lateral-flexion (p = 0.001), right rotation (p = 0.000) and left rotation (p = 0.005) at 6-months of the study, except for flexion, with significative changes from 3-months of follow up; pressure pain threshold from the first follow-up to the end of the study (p values range: 0.003–0.000).

Conclusion

Four 20-min sessions of manual therapy and exercise, along with a home-exercise program, was found to be more effective than an exercise protocol and a home-exercise program in improving the neck disability index, flexion-rotation test, pain intensity, and pressure pain threshold, in the short, medium, and medium-long term in patients with chronic neck pain and upper rotation restriction. Cervical range of motion improved with the addition of manual therapy in the medium and medium-long term. The high dropout rate may have compromised the external validity of the study.

Effects of a combination of scapular stabilization and thoracic extension exercises for office workers with forward head posture on the craniovertebral angle, respiration, pain, and disability: A randomized-controlled trial

Objectives

This study aims to investigate how exercise programs not directly applied to the cervical spine affect office workers with forward head posture (FHP).

Patients and methods

Between March 2018 and June 2018, a total of 32 office workers with FHP (13 males, 19 females; mean age 36.63 years; range, 23 to 57 years) were randomized either to experimental (n=16) or control groups (n=16). Scapular stabilization and thoracic extension exercises were applied to the experimental group and cervical stabilization and stretching exercises to the control group. The results of the pre-intervention and after six weeks measurement of the craniovertebral angle (CVA), respiration, pain, and disability were compared and analyzed.

Results

For intra-group comparison, both groups showed significant differences (p<0.05) in CVA, forced expiratory volume at 1 sec (FEV1), Visual Analog Scale (VAS), and neck disability index at pre- and post-intervention, while only the experimental group showed a significant difference (p<0.05) in maximum inspiratory pressure, maximum expiratory pressure, and forced vital capacity. For inter-group comparison, a significant difference (p<0.05) between FEV1 and VAS was observed.

Conclusion

The combination of scapular stabilization and thoracic extension exercises, not directly applied to the cervical spine, has an effect on improving the posture, respiration, neck pain, and disability in office workers with FHP.

Evaluation of external stabilization of type II odontoid fractures in geriatric patients-An experimental study on a newly developed cadaveric trauma model

Background

Along with the growing geriatric population, the number of odontoid fractures is steadily increasing. However, the effectiveness of immobilizing geriatric odontoid fractures using a cervical collar has been questioned. The aim of the present study is to analyze the physiological and pathological motion in odontoid fractures and to assess limitation of motion in the cervical spine when applying a cervical collar.

Methods

Motion analysis was performed with wireless motion tracker on unfixed geriatric human cadavers. First, a new geriatric type II odontoid fracture model was developed. In this model, the type II odontoid fracture is operated via a transoral approach. The physiological and pathological flexion and lateral bending of the cervical spine resulting from this procedure was measured. The resulting motion after external stabilization using a cervical collar was analyzed.

Results

The new geriatric type II odontoid fracture model was successfully established using seven unfixed human cadavers. The pathological flexion of the cervical spine was significantly increased compared to the physiological flexion (p = 0.027). Furthermore, the flexion was significantly reduced when a cervical collar was applied. In case of flexion the mean remaining motion was significantly reduced (p = 0.0017) from 41° to 14°. For lateral bending the mean remaining motion was significantly reduced (p = 0.0137) from 48° to 18°.

Conclusions

In case of type II odontoid fracture, flexion and lateral bending of the cervical spine are increased due to spinal instability. Thus, if an odontoid fracture is suspected in geriatric patients, the application of a cervical collar should always be considered since external stabilization can significantly reduce flexion and lateral bending.

Effects of Sling-Based Thoracic Active Exercise on Pain and Function and Quality of Life in Female Patients with Neck Pain: A Randomized Controlled Trial

This study aimed to investigate the effects of sling-based thoracic active exercise on pain, function, and quality of life in female patients with neck pain. A total of 27 female patients with neck pain were divided into the sling-based thoracic active exercise group (n = 14) and the control group (n = 13). The study group performed a sling-based thoracic active exercise with cervical manual therapy for 50 min a day, twice a week for 4 weeks, whereas the control group performed a placebo exercise with cervical manual therapy in the same manner as the study group. Evaluation of the degree of pain before and after treatment was based on the pressure pain threshold and numeric pain rating scale scores. The craniovertebral angle and neck disability index (NDI) were used to evaluate neck function, and quality of life was measured using the Short Form-36. Afterwards, the patients’ pressure pain thresholds were significantly increased, and the numeric pain rating scale score was significantly decreased in both groups (p < 0.05). In terms of function, the craniovertebral angle was significantly increased in both groups (p < 0.05), and neck dysfunction significantly decreased (p < 0.05). The quality of life significantly increased in both groups (p < 0.05). The pressure pain threshold, craniovertebral angle, neck dysfunction index, and quality of life scores (p < 0.05) were significantly different between groups, except the numeric pain scale score. Our results showed that sling-based thoracic active exercise is effective in reducing pain and improving function and quality of life in female patients with neck pain, thus emphasizing the need for thoracic treatment for such patients.

Effects of Cervical Spine Mobilization on Respiratory Function and Cervical Angles of Stroke Patients: A Pilot Study

The forward head posture (FHP) of stroke patients has a negative impact on respiratory function. Cervical spine mobilization is a manual therapy technique that used to prevent and treat FHP and respiratory function. This pilot study investigated whether cervical spine mobilization can effectively improve outcomes following FHP and respiratory function of stroke patients. Twenty-four patients participated in our assessor-blinded randomized controlled trial. All the participants received neurodevelopmental treatments (gait training and trunk rehabilitation). The experimental group additionally received 15-min sessions of cervical spine mobilization three times per week for 4 weeks. The control group received cervical spine sham mobilization during the same period. For the cervical angles, the cranial vertebral angle (CVA) and cranial rotation angle (CRA) were measured. A respiratory function test was performed to measure the forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), peak expiratory flow (PEF), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and chest circumferences (upper and lower chest sizes). Except for MIP, there was no significant difference between the experimental group and the control group. The CVA and CRA were significantly increased in the experimental group only. Cervical spine mobilization improved cervical angles and inspiratory function of the stroke patients in this study. However, a comparative study with a larger number of patients is needed to confirm this finding from our pilot study, which had a small sample size.

Effects of sling-based manual therapy on cervicothoracic junction in patients with neck pain and forward head posture: A randomized clinical trial

OBJECTIVE

The purpose of this study was to investigate the effect of 4 weeks of sling-based manual therapy on the cervicothoracic junction (CTJ) area in patients with neck pain and forward head posture.

DESIGN

Single-blind randomized controlled trial.

SETTING

Outpatient, Chonbuk National University hospital, Republic of Korea.

SUBJECTS

A total of 22 participants with neck pain (Numeric Pain Rating Scale >3) and forward head posture (craniovertebral angle <51) were randomly assigned to a CTJ group or a control group (n = 11 each).

INTERVENTION

In the control group, joint mobilization and motor control training was applied for the upper cervical spine (C0-C1). The CTJ group applied the same intervention to the upper cervical spine and cervicothoracic junction (C7-T3).

MAIN MEASURES

Numeric pain rating scale and neck disability index, craniovertebral angle, active range of motion, and muscle activity were evaluated before and after 4 weeks of intervention.

RESULT

The CTJ group participants showed significant improvement in the craniovertebral angle and cervical extension range after the intervention than the control group (P = 0.025, P = 0.001). While both groups presented significant differences after the intervention regarding Numeric pain rating scale, neck disability index, and muscle activity (sternocleidomastoid and anterior scalene muscle), there were no statistically significant differences between the groups (P > 0.05).

CONCLUSION

Our results suggest that the CTJ and the upper cervical region in patients with neck pain and forward head posture represent an area which if approached by manual therapy, improves cervical mobility and posture.

Does the Addition of Manual Therapy Approach to a Cervical Exercise Program Improve Clinical Outcomes for Patients with Chronic Neck Pain in Short- and Mid-Term? A Randomized Controlled Trial

Chronic neck pain is one of today’s most prevalent pathologies. The International Classification of Diseases categorizes four subgroups based on patients’ associated symptoms. However, this classification does not encompass upper cervical spine dysfunction. The aim is to compare the short- and mid-term effectiveness of adding a manual therapy approach to a cervical exercise protocol in patients with chronic neck pain and upper cervical spine dysfunction. Fifty-eight subjects with chronic neck pain and upper cervical spine dysfunction were recruited (29 = Manual therapy + Exercise; 29 = Exercise). Each group received four 20-min sessions, one per week during four consecutive weeks, and a home exercise regime. Upper flexion and flexion-rotation test range of motion, neck disability index, craniocervical flexion test, visual analogue scale, pressure pain threshold, global rating of change scale, and adherence to self-treatment were assessed at the beginning, end of the intervention and at 3- and 6-month follow-ups. The Manual therapy + Exercise group statistically improved short- and medium-term in all variables compared to the Exercise group. Four 20-min sessions of Manual therapy + Exercise along with a home-exercise program is more effective in the short- to mid-term than an exercise protocol and a home-exercise program for patients with chronic neck pain and upper cervical dysfunction.

A Comparison Study of Posture and Fatigue of Neck According to Monitor Types (Moving and Fixed Monitor) by Using Flexion Relaxation Phenomenon (FRP) and Craniovertebral Angle (CVA)

This study quantified the neck posture and fatigue using the flexion relaxation phenomenon (FRP) and craniovertebral angle (CVA); further, it compared the difference between the level of fatigue and neck posture induced by two types of monitors (regular fixed monitor and moving monitor). Twenty-three male participants were classified into two groups—the low-flexion relaxation ratio (FRR) group and the normal-FRR group, depending on the FRR value. All participants performed a document task for 50 min using both types of monitors. It was found that the FRR values significantly decreased after the documentation task. The CVA analysis showed that the moving monitor’s frequency of forward head posture (FHP) was lower than that for the fixed monitor. Overall, the moving monitor worked better than the fixed monitor; this can be interpreted as proof that such monitors can reduce neck fatigue.

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

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.

Completeness of the description of manipulation and mobilisation techniques in randomized controlled trials in neck pain; A review using the TiDieR checklist

STUDY DESIGN

A secondary analysis of a systematic review.

BACKGROUND

Manipulations or mobilizations are commonly used interventions in patients with mechanical neck pain. The treatment effects have often been studied in randomized controlled trials (RCT) which are generally considered the gold standard in evaluating the treatment effects, mainly due to its high internal validity. External validity is defined as the extent to which the effects can be generalised to clinical practice. An important prerequisite for this is that interventions used in clinical trials can be replicated in clinical practice. It can be questioned if interventions utilized in randomized controlled trials can be translated into clinical practice.

OBJECTIVES

The overall aim of this study is to examine whether the quality of the description of manipulation and mobilization interventions is sufficient for to replication of these interventions in clinical practice.

METHODS

A comprehensive literature search was performed. Two independent researchers used the Template for Intervention Description and Replication (TIDieR) which is a 12-item checklist for describing the completeness of the interventions.

RESULTS

Sixty-seven articles were included that used manipulation and/or mobilization interventions for patients with mechanical neck pain. None of the articles describe the intervention e.g. all the items on the TIDieR list. Considering item 8 (a-f) of the TIDieR checklist only one article described the used techniques completely.

CONCLUSION

Manipulation or a mobilization interventions are poorly reported in RCTs, which jeopardize the external validity of RCTs, making it difficult for clinicians and researchers to replicate these interventions.

Impact of Cervical Sensory Feedback for Forward Head Posture on Headache Severity and Physiological Factors in Patients with Tension-type Headache: A Randomized, Single-Blind, Controlled Trial

BACKGROUND Tension-type headache (TTH) decreases the ability to concentrate and function during daily activities in affected patients. As most patients with TTH exhibit forward head posture (FHP). Various interventions have been proposed to resolve TTH. However, research regarding the efficacy of these interventions remains lacking. The present study aimed to investigate the association between FHP and TTH, and to evaluate the efficacy of various intervention methods on headache symptoms and other clinical variables in patients with TTH induced by FHP. MATERIAL AND METHODS Participants were randomly allocated to 3 groups: biofeedback (BF, n₁=21), manual therapy (MT, n₂=20) and, stretching (ST, n₃=21). Interventions were conducted 3 times per week for 4 weeks. Craniovertebral angle (CVA), electroencephalographic findings for attention, stress, and pressure-pain threshold (PPT), headache on activities of daily living (Henry Ford Headache Disability Inventory, HDI), and quality of life (QoL) assessments were obtained pre-intervention, post-intervention, and at the 2-week follow-up. RESULTS The correlation between CVA and HDI after intervention (R²=0.324, P<0.001), and at 2-week follow-up (R²=0.115, P<0.01) are significant. BF was associated with significant improvements in CVA (F₂,₅₉=3.393, P<0.001, η^2/P=0.130), attention (F₂,₅₉=5.186, P<0.01, η^2/P=0.150), stress [skin temperature (F₂,₅₉=6.005, P<0.001, η^2/P=0.169) and skin conductance (F₂,₅₉=4.900, P<0.01, η^2/P=0.142)], PPT (F₂,₅₉=5.050, P<0.01, η^2/P=0.146), HDI (F₂,₅₉=3.303, P<0.01, η^2/P=0.101), and QoL (F₂,₅₉=3.409, P<0.05, η^2/P=0.104). CONCLUSIONS Our findings indicate that BF was more effective than MT and ST in the treatment of TTH due to FHP. Such findings highlight the need to develop and promote a controlled exercise program to facilitate a return to normal daily activities in patients with TTH due to FHP.

Biomechanical Evaluation of an Anterior Upper Thoracic Plate Fixation System: An In Vitro Human Cadaveric Study

OBJECTIVE

This study aimed to evaluate the biomechanical characteristics of the anterior upper thoracic plate fixation system (AUTP).

METHODS

Twelve specimens were divided into 2 groups: the AUTP group and the anterior cervical locking plate (ACLP) group. Bone mineral density was assessed in all specimens. The specimens were loaded with pure bending moments of ±4 Nm to move toward extension/flexion, right/left lateral tilt, and right/left axial rotation. Each specimen was tested in 3 load cycles under 3 conditions (native, destabilized, and torsion). The tightening moments were assessed in every screw using a torsion meter.

RESULTS

The tightening moment of the AUTP screws was more pronounced than the ACLP (P < 0.05). Significant decreases after stabilization with the AUTP compared with the native situation were observed in the AUTP group (P < 0.05). In terms of the direction of lateral tilt and torsion, the neutral zone increased significantly after stabilization with the AUTP compared with the native situation (P < 0.05).

CONCLUSIONS

The AUTP was shown to provide more rigidity to the destabilized spine than the ACLP.
