Effect of Forward Head Posture on Resting State Brain Function.

Forward head posture (FHP) is a common postural problem experienced by most people. However, its effect on brain activity is still unknown. Accordingly, we aimed to observe changes in brain waves at rest to determine the effect of FHP on the nervous systems. A total of 33 computer users (Male = 17; Female = 16; age = 22.18 ± 1.88) were examined in both FHP and neutral posture. For each session, brain waves were measured for 5 min, and then muscle mechanical properties and cranio-vertebral angle (CVA) were measured. Changes in brain waves between the neutral posture and FHP were prominent in gamma waves. A notable increase was confirmed in the frontal and parietal lobes. That is, eight channels in the frontal lobe and all channels in the parietal lobe showed a significant increase in FHP compared to neutral posture. Additionally, FHP changes were associated with a decrease in CVA (p < 0.001), an increase in levator scapulae tone (Right, p = 0.014; Left, p = 0.001), and an increase in right sternocleidomastoid stiffness (p = 0.002), and a decrease in platysma elasticity (Right, p = 0.039; Left, p = 0.017). The change in CVA was found to have a negative correlation with the gamma activity (P7, p = 0.044; P8, p = 0.004). Therefore, increased gamma wave activity in FHP appears to be related to CVA decrease due to external force that was applied to the nervous system and cervical spine.

Effects of Stretching or Strengthening Exercise on Spinal and Lumbopelvic Posture: A Systematic Review with Meta-Analysis.

BACKGROUND: Abnormal posture (e.g. loss of lordosis) has been associated with the occurrence of musculoskeletal pain. Stretching tight muscles while strengthening the antagonists represents the most common method to treat the assumed muscle imbalance. However, despite its high popularity, there is no quantitative synthesis of the available evidence examining the effectiveness of the stretch-and-strengthen approach. METHODS: A systematic review with meta-analysis was conducted, searching PubMed, Web of Science and Google Scholar. We included controlled clinical trials investigating the effects of stretching or strengthening on spinal and lumbopelvic posture (e.g., pelvic tilt, lumbar lordosis, thoracic kyphosis, head tilt) in healthy individuals. Effect sizes were pooled using robust variance estimation. To rate the certainty about the evidence, the GRADE approach was applied. RESULTS: A total of 23 studies with 969 participants were identified. Neither acute (d = 0.01, p = 0.97) nor chronic stretching (d=-0.19, p = 0.16) had an impact on posture. Chronic strengthening was associated with large improvements (d=-0.83, p = 0.01), but no study examined acute effects. Strengthening was superior (d = 0.81, p = 0.004) to stretching. Sub-analyses found strengthening to be effective in the thoracic and cervical spine (d=-1.04, p = 0.005) but not in the lumbar and lumbopelvic region (d=-0.23, p = 0.25). Stretching was ineffective in all locations (p > 0.05). CONCLUSION: Moderate-certainty evidence does not support the use of stretching as a treatment of muscle imbalance. In contrast, therapists should focus on strengthening programs targeting weakened muscles.

Efficacy of ultrasound therapy with neck retraction exercises vs. ultrasound therapy with deep cervical flexor training for excessive screen time users: a pilot randomized controlled study.

[Purpose] To compare the effectiveness of ultrasound therapy in combination with neck retraction exercises and deep cervical flexor training on pain, forward head posture, and deep cervical flexor muscle strength in excessive screen time users. [Participants and Methods] This 4-week intervention study included 36 participants with forward head posture, categorized into three groups: 1) ultrasound therapy with neck retraction exercises 2) ultrasound therapy with deep cervical flexor training, and 3) a control group. The outcomes were pain, forward head posture, and strength of the deep cervical flexor muscles. [Results] The strength of the deep cervical flexor muscles exhibited a notable increase, indicating a relatively higher mean value in the first intervention group. Upon follow-up, significant changes in all outcomes were observed between the first intervention group and the control group. Also, significant differences were revealed in the deep cervical flexor muscles between the second intervention group and the control group. [Conclusion] Ultrasound therapy with neck retraction exercises could have a more positive effect on pain, forward head posture, and strength of the deep cervical flexor muscles in comparison to ultrasound therapy with deep cervical flexor training for excessive screen time users.

Unsupervised machine learning for clustering forward head posture, protraction and retraction movement patterns based on craniocervical angle data in individuals with nonspecific neck pain.

OBJECTIVES: The traditional understanding of craniocervical alignment emphasizes specific anatomical landmarks. However, recent research has challenged the reliance on forward head posture as the primary diagnostic criterion for neck pain. An advanced relationship exists between neck pain and craniocervical alignment, which requires a deeper exploration of diverse postures and movement patterns using advanced techniques, such as clustering analysis. We aimed to explore the complex relationship between craniocervical alignment, and neck pain and to categorize alignment patterns in individuals with nonspecific neck pain using the K-means algorithm. METHODS: This study included 229 office workers with nonspecific neck pain who applied unsupervised machine learning techniques. The craniocervical angles (CCA) during rest, protraction, and retraction were measured using two-dimensional video analysis, and neck pain severity was assessed using the Northwick Park Neck Pain Questionnaire (NPQ). CCA during sitting upright in a comfortable position was assessed to evaluate the resting CCA. The average of midpoints between repeated protraction and retraction measures was considered as the midpoint CCA. The K-means algorithm helped categorize participants into alignment clusters based on age, sex and CCA data. RESULTS: We found no significant correlation between NPQ scores and CCA data, challenging the traditional understanding of neck pain and alignment. We observed a significant difference in age (F = 140.14, p < 0.001), NPQ total score (F = 115.83, p < 0.001), resting CCA (F = 79.22, p < 0.001), CCA during protraction (F = 33.98, p < 0.001), CCA during retraction (F = 40.40, p < 0.001), and midpoint CCA (F = 66.92, p < 0.001) among the three clusters and healthy controls. Cluster 1 was characterized by the lowest resting and midpoint CCA, and CCA during pro- and -retraction, indicating a significant forward head posture and a pattern of retraction restriction. Cluster 2, the oldest group, showed CCA measurements similar to healthy controls, yet reported the highest NPQ scores. Cluster 3 exhibited the highest CCA during protraction and retraction, suggesting a limitation in protraction movement. DISCUSSION: Analyzing 229 office workers, three distinct alignment patterns were identified, each with unique postural characteristics; therefore, treatments addressing posture should be individualized and not generalized across the population.

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.

Efficacy of posture correction band vs. McKenzie's exercises on pulmonary function and chest expansion in asymptomatic population with forward head posture.

BACKGROUND: Poor posture and sedentary lifestyle cause Forward Head Posture (FHP). To correct this, a Posture Correction Band (PCB) is commonly used. However, the efficacy of PCB vs. McKenzie's Exercises on pulmonary function and chest expansion in asymptomatic individuals with FHP was not known. OBJECTIVE: This study aimed to determine the efficacy of PCB vs. McKenzie's Exercises on the Pulmonary function and chest expansion in asymptomatic population with FHP. METHODOLOGY: A Randomized control trial was conducted on forty-two subjects with FHP. Subjects were divided in two groups. G1 group was educated as per McKenzie's exercises to perform once daily for a month. The Pulmonary function test and chest expansion of this group was performed before and after the McKenzie exercises. G2 group wore PCB for 2 h daily for a month and their PFT and chest expansion was recorded before and after the trial. FVC, FEV1, FEV1/FVC ratio, PEFR and Chest expansion were measured. RESULTS: The P-value of FVC, FEV1, FEV1/FVC ratio and PEFR between the groups (treatment group) was significant as 0.000, 0.000, 0.000 and 0.02 respectively. The chest expansion was non-significant between the groups (treatment group) with P-value as 0.553, 0.493 and 0.699 at axillary, 4th intercostal and xiphisternum level respectively. The P-value of FVC, FEV1, FEV1/FVC ratio and PEFR between the groups (control group) was non-significant as 0.682, 0.149, 0.424 and 0.414 respectively. The chest expansion was also non-significant between the groups (control group) with P-value as 0.853, 0.651 and 0.763 at axillary, 4th intercostal and xiphisternum level. CONCLUSION: The study concluded that there were significant effects of both Posture Correction Band and Mc'Kenzie exercises on pulmonary function with greater difference seen with PCB and non-significant effects on chest expansion in terms of P-values in treatment group.

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.

Two Methods of Forward Head Posture Assessment: Radiography vs. Posture and Their Clinical Comparison.

Background: Forward head posture (FHP) and altered cervical lordotic curvatures are common spine displacements often associated with neck pain and disability. Two primary categories for determining FHP exist: radiographic and postural measurements. Methods: This study investigated the correlation between the craniovertebral angle (CVA), the radiographically measured C2-C7 sagittal vertical axis (SVA), and cervical lordosis (absolute rotation angle: ARA C2-C7) in a sample of participants with chronic myofascial pain (CMP). In 120 participants, we performed both a postural measurement of the CVA and a lateral cervical radiograph, where the C2-C7 SVA and ARA C2-C7 were measured. A linear-regression R2 value to assess the correlation between the CVA, C2-C7 SVA, and ARA C2-C7 was sought. Results: A statistically significant weak linear fit was identified (Spearman's r = 0.549; R2 = 0.30, p < 0.001) between the CVA and C2-C7 SVA, having considerable variation between the two measures. A statistically significant linear fit (very weak) was identified for the lordosis ARA C2-C7 and the CVA: Spearman's r = 0.524; R2 = 0.275; p < 0.001. A value of 50° for the CVA corresponded to a value of 20 mm for the C2-C7 SVA on an X-ray. Conclusion: While the CVA and radiographic C2-C7 SVA are weakly correlated in an individual, they seem to represent different aspects of sagittal cervical balance. The CVA cannot replace radiographically measured cervical lordosis. We recommend that more emphasis be given to radiographic measures of sagittal cervical alignment than the CVA when considering patient interventions.

Effects of Myofascial Release Technique along with Cognitive Behavior Therapy in University Students with Chronic Neck Pain and Forward Head Posture: A Randomized Clinical Trial.

The purpose of this randomized controlled trial was to evaluate the effectiveness of the Myofascial Release Technique (MRT) along with Cognitive Behavioral Therapy (CBT) on pain, craniovertebral angle (CVA), and neck disability in university students with chronic neck pain and forward head posture. A total of sixty-six eligible participants with chronic neck pain and forward head posture were randomized into the Myofascial Release Therapy (MRT) group (n = 33) and MRT and Cognitive Behavior Therapy (CBT) group (n = 33). Clinical outcomes included neck pain measured using the numerical pain rating scale, neck disability measured through the neck disability index, and forward head posture measured through the cranial vertebral angle. The outcomes were assessed at baseline and the four and eight weeks after the intervention. Both groups showed significant improvement in pain intensity, CVA, and neck disability after the intervention. However, the CBT group demonstrated greater improvements than the MRT group. The difference in outcomes between the groups was statistically significant. Myofascial Release Therapy combined with CBT is an effective treatment method for patients with chronic neck pain and forward head posture.

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 Mobilization on Balance and Gait Parameters in Individuals With Stroke: A Randomized Controlled Trial.

Stroke is a significant health problem that may result in long-term functional deficits. Balance and walking problems are among the most common post-stroke deficits, and they may negatively affect quality of life. Our aim in this study was to investigate the effects of cervical mobilization on balance and gait parameters after stroke. Participants were 24 adults (aged 30-65 years), who scored 24 or above on the Standardized Mini-Mental State Exam (MMSE) and no more than 3 on the Modified Rankin scale. Participants were randomly assigned to either an experimental Bobath therapy and cervical mobilization group (n = 12) or a control group who received Bobath therapy and a sham application (n = 12). Both groups received 60 minutes of Bobath therapy three times a week for four weeks; additionally, the experimental group received 15 minutes of cervical mobilization in each session, while the control group received 15 minutes of spinal sham mobilization each session. Pre and post treatment, we assessed all participants' demographic characteristics, gait parameters, balance parameters, and forward head posture values using a clinical data assessment form, spatiotemporal gait analysis (LEGSystm), portable computerized kinesthetic balance device (SportKAT 550), and craniovertebral angle (CVA), respectively. The groups showed no significant differences in their initial demographic and clinical characteristics (age, sex, stroke duration and disability levels.). In comparing changes on variables of interest, we observed significant experimental versus control group improvements in balance parameters except for their left side balance score (right side, left side, forward, backward and total balance scores were significant at p = .003, p = .089, p < .001, p = .022, p < .001, respectively), gait parameters (stride number, stride length, stride time, stride velocity, cadance at p = .007, p = .019, p = .013, p = .005, p = .001, respectively) and CVA (p < .001). Also, there were findings in favor of the experimental group on the modified timed up and go test on walk out, mid turn, walk back and total times (p = .028, p = .001, p = .016, and p = .001, respectively),but not for sit-to-stand time or stand-to-sit time. Clinicians involved in stroke rehabilitation should assess and treat the cervical region to enhance rehabilitation effectiveness.

The relationship between myofascial trigger points sensitivity, cervical postural abnormality, and clinical tension-type headache parameters.

BACKGROUND: Myofascial Trigger Points (MTrPs) play a significant role in the pathogenesis of Tension Type Headache (TTH). Abnormal cranio-cervical posture has been linked to various types of headaches. However, the correlation between MTrPs sensitivity, cervical postural alignment, and clinical measures of headache has not been extensively studied in patients with TTH. OBJECTIVES: To investigate the relationship between MTrPs sensitivity in cervical and pericranial muscles, cervical postural abnormality, and clinical headache parameters in patients with TTH. Furthermore, to investigate the effect of sex on the examined variables and their association with headache type (episodic vs chronic TTH). METHODS: A total of 72 patients with TTH of both sexes were enrolled in this study. Headache frequency and disability as clinical measures of headache, pressure pain threshold (PPT) of bilateral upper trapezius (UT) and suboccipital (SUB) muscles, cervical lordosis angle (CA), and anterior head translation (AHT) were measured. RESULTS: Pericranial MTrPs sensitivity did not demonstrate any correlation with clinical headache parameters or cervical postural abnormality. However, there was a significant correlation between the frequency of headaches and the level of disability (r = 0.32, P < 0.05). In addition, episodic TTH was more prevalent in females who exhibited greater AHT and MTrPs sensitivity of both bilateral UT and right SUB muscles than males. CONCLUSIONS: There was no correlation found between the frequency of headaches and the level of disability with measures of cervical posture alignment or MTrPs sensitivity in individuals with TTH.. Based on findings, Clinicians should consider sex differences when assessing patients with TTH.

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.

Alleviation of shoulder injury related to vaccine administration (SIRVA) pain and disability following COVID-19 vaccine with chiropractic biophysics® (CBP®) methods: a case report and long-term follow-up with global implications.

[Purpose] To present the dramatic improvement in posture, radiographic parameters and the alleviation of neck and severe shoulder pain related to shoulder injury associated with vaccine administration (SIRVA) after a COVID-19 injection with a shoulder mobility and posture rehabilitation program. [Participant and Methods] A middle-aged male presented complaining of severe left shoulder pain evolving since receiving a COVID-19 vaccination. The pain was severe and throbbed into the neck. Posture analysis showed a chronic stooped posture with forward head posture and thoracic hyperkyphosis. Treatment included 42 sessions of Chiropractic Biophysics® technique and a shoulder rehabilitation program using three-dimensional vibration. [Results] At 4-months, the patient reported no neck or shoulder pain. There was a 60% decrease in neck disability. The forward head decreased 34 mm, thoracic hyperkyphosis decreased 13°, and T1-T12 forward lean decreased 73 mm, among other radiographic parameters. Re-assessment after 26-months showed maintenance of the treatment induced posture/x-ray corrections and shoulder pain relief. [Conclusion] This case demonstrates immediate and long-term improvement in a patient suffering from COVID-19 vaccine SIRVA, concomitant with neck pain and disability as well as significant radiographic postural/spinal deformity. These conditions all improved and were maintained at a 2 year follow-up without further treatment.

Physiotherapeutic Interventions for Upper Cross Syndrome: A Systematic Review and Meta-Analysis.

Upper cross syndrome is a postural dysfunction that can cause a variety of upper-body musculoskeletal problems. Early detection and physiotherapy can help to prevent further complications. However, no systematic review has evaluated the effect of various physiotherapy intervention strategies to treat this syndrome. Therefore, this study aims to conduct a detailed methodological literature search of the most effective treatment strategies available for the correction of upper cross syndrome. Prospective human subject studies published in the English language that report the assessment and rehabilitation of upper cross syndrome were included. Clinical trials (randomized and non-randomized) were included when compared to a comparator, control group, and no treatment. The search was limited to human subjects and English-language articles. Outcome measures included craniovertebral angle, kyphotic angle, rounded shoulder, neck or shoulder pain, neck range of motion, electromyographic activity of neck or scapular muscles, and functional limitations. To evaluate the methodological quality of randomized controlled trials, the Cochrane collaboration tool was employed. For non-randomized studies, the Risk of Bias in Non-randomized Studies of Intervention was used. The Grading of Recommendations, Assessment, Development, and Evaluation system was used to rate the effectiveness of the evidence. A random-effect meta-analysis was performed for quantitative analysis to report significant differences based on calculated mean differences, with matching 95% confidence intervals (CIs) whenever possible. Out of the 34 potentially relevant articles, 18 were included. The postural variables including craniovertebral angle, kyphotic angle, and rounded shoulder showed a significant improvement with the physiotherapy group compared to the no-treatment group (standardized mean difference = -1.78; 95% CI = -2.68 to -0.87; p = 0.0001). Secondary outcomes such as pain and functional limitation showed a significant difference when advanced manual therapy techniques were used compared to conventional therapy (standardized mean difference = -0.71; 95% CI = -1.04 to -0.39; p< 0.0001; and standardized mean difference = -0.57; 95% CI = -1.00 to -0.14; p = 0.009, respectively). Exercise therapy was found to be beneficial in correcting postural alignment and movement patterns, while manual therapy was found to be similarly effective in pain reduction and functional improvement.

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.

Remission of Dowager's hump by manipulative correction of spinal alignment: a case report.

Dowager's hump is described as excessive kyphotic curvature in the thoracic spine with a Cobb angle of more than 40 degrees. This case report presents a 61 years old female office clerk who experienced headaches and neck pain for 3 years that extended into her right shoulder and upper chest. She consulted her primary care physician two months before seeing the chiropractor when the neck pain worsened. A diagnosis of cervicalgia related to osteoarthritis was made based on cervical and thoracic X-ray findings. The patient received non-steroid anti-inflammatory drugs (celecoxib and etoricoxib) and stretching exercises at home. At the onset of chiropractic care, radiographs showed loss of cervical lordosis, narrowing at the C4-5, C5-C6, and C6-7 intervertebral disc space with marginal osteophytes. Based on these findings, a working diagnosis of cervicogenic headache was established. After treatment for 9 months, the patient showed improvement in symptoms and function from cervical curve radiographic change and dextro-convexity of the thoracic spine. Avoiding forward head flexion and maintaining correct posture in daily activities will be key mechanisms to prevent the reoccurrence of Dowager's hump. The improvement of symptoms following chiropractic therapy has been shown to correlate with radiographic markers of spinal realignment.

Body landmarks and genetic algorithm-based approach for non-contact detection of head forward posture among Chinese adolescents: revitalizing machine learning in medicine.

Addressing the current complexities, costs, and adherence issues in the detection of forward head posture (FHP), our study conducted an exhaustive epidemiologic investigation, incorporating a comprehensive posture screening process for each participant in China. This research introduces an avant-garde, machine learning-based non-contact method for the accurate discernment of FHP. Our approach elevates detection accuracy by leveraging body landmarks identified from human images, followed by the application of a genetic algorithm for precise feature identification and posture estimation. Observational data corroborates the superior efficacy of the Extra Tree Classifier technique in FHP detection, attaining an accuracy of 82.4%, a specificity of 85.5%, and a positive predictive value of 90.2%. Our model affords a rapid, effective solution for FHP identification, spotlighting the transformative potential of the convergence of feature point recognition and genetic algorithms in non-contact posture detection. The expansive potential and paramount importance of these applications in this niche field are therefore underscored.

The Correlation between Neck Pain and Disability, Forward Head Posture, and Hyperkyphosis with Opium Smoking: A Cross-Sectional Study from Iran.

Opium smoking has been a common practice in Iran for many years, with people often smoking for long hours. During the COVID-19 pandemic, there was an increase in opium smoking due to false beliefs about its protective effects against COVID-19 infection. In this study, we aimed to examine the association between the non-ergonomic positions associated with traditional opium smoking in Iran and the development of neck pain and disability, forward head posture (FHP), and hyperkyphosis (HK). In this cross-sectional, correlational study, a total of 120 individuals who smoked opium were selected based on the inclusion criteria. They were interviewed about their addiction profile using the Lite version of the Addiction Severity Index and the Leeds Dependence Questionnaire. The presence of neck pain and disability was also evaluated using the Visual Analog Scale and the Neck Disability Index. The participants were examined for FHP via side-view photography and for HK using a flexible ruler. Data were analyzed using correlation coefficient tests and stepwise linear regression analysis. Based on the results, homelessness, the lifetime duration of opium smoking (in months), the duration of daily opium smoking (in minutes), and the severity of drug dependence had significant relationships with the severity of neck pain, neck disability, FHP, and HK. Homelessness was the strongest predictor of neck pain and disability (R2 = 0.367, p < 0.001), FHP (R2 = 0.457, p < 0.001), and HK (R2 = 0.476, p < 0.001), followed by the lifetime duration of opium smoking and the duration of daily opium smoking, respectively, in which R2 increased to 0.505 (p = 0.011), 0.546 (p = 0.022), and 0.570 (p = 0.004) with the addition of two other variables. Overall, an increase in the duration of sitting in non-ergonomic positions could lead to neck pain and disability, FHP, and HK due to the non-neutral posture of opium smokers.

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.
