Superficial fascia displacement in cervical flexion: differentiating myofascial pain syndrome, a cross-sectional study.

Myofascial pain syndrome (MPS) is primarily characterized by myofascial trigger points related to fascial adhesions. MPS hinders fascial flexibility and mobility, leading to myofascial limitations, dysfunctional movement, and limitation of motion (LOM). This study determined the association of age, sex, type of work, symptom chronicity, symptom laterality, cervical LOM, altered direction of fascial displacement, and magnitude of superficial fascial displacement during active cervical flexion with the clinical diagnosis of MPS. A cross-sectional study selectively included MPS and non-MPS participants from different workplaces from January to October 2019. The MPS group exhibited clinical symptoms like tender spots, recognized pain patterns, and local twitch response upon palpation, often accompanied by cervical LOM. The non-MPS group lacked these symptoms, and those with certain pre-existing conditions or recent physiotherapy were not part of the study. Participants performed cervical active range of motion (AROM) while a sonographer recorded superficial fascial displacement utilizing ultrasound, which was later analyzed by three physiotherapists with the Tracker. Aiming for a multiple regression R-squared of 0.2, the target was 384 participants to account for a 20 % dropout, resulting in 307 participants after attrition. To explore the relationships between MPS and various factors, logistic regression models, rigorously tested for reliability and validity, were utilized. In the study, there were 192 participants with MPS and 137 without MPS. The median ages were 33 years for the non-MPS group and 38 years for the MPS group. The adjusted model found significant links for sex (odds ratio [OR]=2.63, p<0.01), symptom chronicity (OR=8.28, p<0.01), and cervical LOM (OR=3.77, p=0.01). However, age and the presence of nodules/taut bands were not statistically significant (p>0.05). Also, the type of work, the direction of fascial displacement, and the difference in superficial fascial displacement during cervical flexion did not show a significant association with the clinical diagnosis of MPS (p>0.05). The adjusted model had a sensitivity of 73.80 % and a specificity of 81.34 %, correctly identifying 84.66 % of positive cases and 68.99 % of negative ones, resulting in an overall accuracy of 76.95 % in predicting MPS. We provided an in-depth examination of MPS, identifying sex, duration of symptoms, and cervical LOM as significant predictive factors in its diagnosis. The study emphasizes the critical role of these variables in the accurate diagnosis of MPS, while delineating the comparatively minimal diagnostic value of other factors such as age, type of occupation, presence of nodules or taut bands, and variations in fascial displacement. This study underscores the imperative for further scholarly inquiry into the role of fascial involvement in musculoskeletal disorders, with the objective of enhancing both the theoretical understanding and diagnostic practices in this medical domain.

Comparison of breathing pattern and diaphragmatic motion in patients with unilateral cervical radiculopathy and asymptomatic group

BackgroundThe associations between neck pain and respiratory dysfunction were clarified in patients with neck pain. There is dearth of evidence on pulmonary dysfunction and diaphragmatic excursion in patients with unilateral cervical radiculopathy (CR). The purpose of this study was to compare the breathing pattern and diaphragmatic excursion in patients with unilateral CR with those in an asymptomatic group.MethodsTwenty-five patients with unilateral CR and 25 asymptomatic individuals aged between 30 and 55 participated in this study. Diaphragmatic motion, breathing pattern, active cervical range of motion and kinesiophobia were investigated in both groups by using fluoroscopy, manual assessment of respiratory motion (MARM), cervical range of motion device, and Tampa scale of kinesiophobia. Statistical significance was set at 0.05.ResultsNo statistically significant differences were found between the two groups with regard to sex, age and body mass index. The mean excursion of the hemi diaphragm on the involved side (the side of CR) was significantly lower than that on the uninvolved side in patients with unilateral CR with a large effect size. The excursion of the involved hemi diaphragm in patients was reduced compared to the matched hemi diaphragm in the control group. There was no significant difference between the hemi diaphragms excursion in the control group. The results of the MARM variables showed that the volume of breathing and the percentage rib cage motion in normal and deep breathing were significantly different between the two groups, but there was no significant difference in the balance of breathing between the two groups. Additionally, the active cervical range of motion was reduced in these patients in comparison to the control group, and it was less on the involved side than on the uninvolved side.ConclusionThe results of this study revealed a dysfunctional breathing pattern in normal and deep breathing and a unilateral reduction in diaphragmatic excursion on the side of radiculopathy in patients with unilateral CR compared to the control group.

Elastic Taping Application on the Neck: Immediate and Short-Term Impacts on Pain and Mobility of Cervical Spine.

The aim of this study was to measure the effects on three-planar active cervical range of motion (ACROM) and self-perceived pain of elastic taping (ET) application in the cervical area. Thirty participants (n: 22-M and 8-F, age 35.4 ± 4.4 years; body height 173.1 ± 8.4 cm; body mass 73.5 ± 12.8 kg) in the study group (SG) and twenty participants (n: 11-M and 9-F, age 32.6 ± 3.9 years; body height 174.9 ± 10.9 cm; body mass 71.2 ± 12.9 kg) in the control group (CG) were recruited. All subjects had neck and cervical pain in baseline condition. Each group performed an ACROM test and measured the perceived pain in the neck based on the Numerical Rating Scale (NRS 0--10, a.u.) at the baseline (T0), after 20' from the ET application (T1), and after three days of wearing the ET application (T2). Between T0 and T1, an ET was applied to the cervical area of the SG participants. Statistical analysis did not show any significant change in CG in any measurement session for ACROM and neck pain parameters. Conversely, the SG showed significant improvements for ACROM rotation to the left (T0 64.8 ± 7.7°-T2 76.0 ± 11.1° p < 0.000) and right (T0 66.0 ± 11.9°-T2 74.2 ± 9.6° p < 0.000), lateral inclination to the left (T0 37.5 ± 6.9°-T2 40.6 ± 10.8° p < 0.000) and right (T0 36.5 ± 7.9°-T2 40.9 ± 5.2° p < 0.000), extension (T0 47.0 ± 12.9°-T2 55.1 ± 12.3° p < 0.001), and flexion (T0 55.0 ± 3.6°-T2 62.9 ± 12.0° p < 0.006). A significant decrease was also measured in SG for pain NRS between T0 and T2 (T0 7.5 ± 1.0°-T1 5.5 ± 1.4-T2 1.4 ± 1.5° p < 0.000). In conclusion, a bilateral and symmetrical ET cervical application is useful to enhance multiplanar ACROM and reduce subjective self-perceived cervical pain when it is needed. Based on the evidence, the use of ET on the neck is recommended for managing neck motion restrictions and pain in adult individuals.

The Magnitude of Physical and Sensory Impairments in Post-traumatic and Non-traumatic Cervicogenic Headaches: A Comparative Study.

Background Cervicogenic headaches can significantly deteriorate the quality of life of patients and decrease their productivity. Few studies have been conducted to assess the magnitude of physical impairments among patients with non-traumatic and post-traumatic cervicogenic headaches. Therefore, this study was conducted to examine and compare the magnitude of cervical physical impairments among patients with post-traumatic cervicogenic headaches in contrast to patients with non-traumatic cervicogenic headaches, migraine, and a group of sex- and age-matched controls who did not have headaches. Methodology This was a comparative study. A total of 104 patients and 30 sex- and age-matched controls were included. The patients were stratified into three groups: post-traumatic cervicogenic headaches (n = 42), non-traumatic cervicogenic headaches (n = 30), and migraines (n = 32). The cervical active range of motion and proprioception were assessed using a goniometer, the craniovertebral angle was measured while the heads of the subjects rested in a comfortable position, the strength of the cervical flexors and extensors was assessed using a hand-held dynamometer, and endurance of the short cervical flexors was assessed while the subjects were in a supine position with no pillow. Skin roll tests were performed in the trapezius and mandibular areas, and pain was measured using the McGill Pain Questionnaire-Short Form. Results Patients in the post-traumatic cervicogenic headache group reported a significantly higher number of headache days (p < 0.001) compared to the controls, patients with migraines, and those with non-traumatic cervicogenic headaches. Patients with post-traumatic cervicogenic headaches showed a significant reduction in total rotation, flexion and extension, lateral bending, and craniovertebral angle compared to the controls, patients with migraines, and those with non-traumatic cervicogenic headaches. On the other hand, the controls endured significantly longer and had stronger neck flexors and extensors compared to the patients in the migraine, non-traumatic, and post-traumatic cervicogenic headache groups, respectively. Patients with post-traumatic cervicogenic headaches significantly reported higher affective and total pain compared to the controls and patients in the migraine group. Conclusions Patients with post-traumatic cervicogenic headaches had significant deficits in the cervical active range of motion in the different planes, endurance, and strength of cervical flexors and extensors compared to the controls and patients with migraine and non-traumatic cervicogenic headaches. Similarly, patients with post-traumatic cervicogenic headaches reported higher affective pain compared to the controls and patients with migraines. The results of this study indicated that patients with post-traumatic cervicogenic headaches have significantly higher physical impairments compared to patients with non-traumatic cervicogenic headaches. These differences warrant caution when combining data from patients with non-traumatic and post-traumatic cervicogenic headaches.

Profiling migraine patients according to clinical and psychophysical characteristics: clinical validity of distinct migraine clusters

AimsInvestigate if different clinical and psychophysical bedside tools can differentiate between district migraine phenotypes in ictal/perictal (cohort 1) and interictal (cohort 2) phases.MethodThis observational study included two independent samples in which patients were subgrouped into distinct clusters using standardized bedside assessment tools (headache frequency, disability, cervical active range of motion, pressure pain threshold in different areas): (A) cohort 1—ictal/perictal migraine patients were subgrouped, based on previous studies, into two clusters, i.e., Cluster-1.1 No Psychophysical Impairments (NPI) and Cluster-1.2 Increased Pain Sensitivity and Cervical Musculoskeletal Dysfunction (IPS-CMD); (B) cohort 2—interictal migraine patients were subgrouped into three clusters, i.e., Cluster-2.1 NPI, Cluster-2.2 IPS, and Cluster-2.3 IPS-CMD. Clinical characteristics (multiple questionnaires), somatosensory function (comprehensive quantitative sensory testing (QST)), and cervical musculoskeletal impairments (cervical musculoskeletal assessment) were assessed and compared across headache clusters and a group of 56 healthy controls matched for sex and age.ResultsCohort 1: A total of 156 subjects were included. Cluster-1.2 (IPS-CMD) had higher headache intensity (p = 0.048), worse headache-related (p = 0.003) and neck-related disability (p = 0.005), worse quality of life (p = 0.003), and higher symptoms related to sensitization (p = 0.001) and psychological burden (p = 0.005) vs. Cluster-1.1(NPI). Furthermore, Cluster-1.2 (IPS-CMD) had (1) reduced cervical active and passive range of motion (p < 0.023), reduced functionality of deep cervical flexors (p < 0.001), and reduced values in all QST(p < 0.001) vs. controls, and (2) reduced active mobility in flexion, left/right lateral flexion (p < 0.045), and reduced values in QST (p < 0.001) vs. Cluster-1.1 (NPI). Cohort 2: A total of 154 subjects were included. Cluster-2.3 (IPS-CMD) had (1) longer disease duration (p = 0.006), higher headache frequency (p = 0.006), disability (p < 0.001), and psychological burden (p = 0.027) vs. Cluster-2.2 (IPS) and (2) higher headache-related disability (p = 0.010), neck-related disability (p = 0.009), and higher symptoms of sensitization (p = 0.018) vs. Cluster-2.1 (NPI). Cluster-2.3(IPS-CMD) had reduced cervical active and passive range of motion (p < 0.034), and reduced functionality of deep cervical flexors (p < 0.001), vs. controls, Custer-2.1 (NPI), and Cluster-2.2 (IPS). Cluster-2.2 (IPS) and 2.3 (IPS-CMD) had reduced QST values vs. controls (p < 0.001) and Cluster-2.1 (p < 0.039).ConclusionA battery of patient-related outcome measures (PROMs) and quantitative bedside tools can separate migraine clusters with different clinical characteristics, somatosensory functions, and cervical musculoskeletal impairments. This confirms the existence of distinct migraine phenotypes and emphasizes the importance of migraine phases of which the characteristics are assessed. This may have implications for responders and non-responders to anti-migraine medications.

Measurement properties of a computer adaptive device, the Senscoordination 3D Cervical Trainer, to assess cervical range of motion in people with neck pain

IntroductionClinicians commonly assess cervical range of motion (ROM) in patients with neck pain. Recently, a new instrument has been developed, the Senscoordination 3D Cervical Trainer (SCT), designed to measure neck ROM in addition to joint position error, static and dynamic balance performance, and performance on a ‘neuro muscular control test’. This study aims to assess the interrater reliability, concurrent validity, and responsiveness of the SCT using the CROM device as a comparator. MethodsOne hundred patients with non-specific neck pain were included and their active cervical ROM was measured in a random order by two raters in succession using both devices simultaneously at baseline and after personalised physiotherapy management, at 12 week follow up. Convergent validity and responsiveness were quantified by a Pearson correlation coefficient. The intraclass correlation coefficient (ICC) was used to calculate the test–retest reliability of the SCT. The smallest detectable change (SDC) was calculated per movement direction and for the total range of motion. ResultsThe correlation between the measures obtained with the CROM device and the SCT was high (0.97 or 0.98 depending on direction of movement). Interrater reliability was high for all directions (ICC ranging from 0.81 to 0.97). The SDC ranged from 6.9 for left cervical rotation to 12.2 for right cervical rotation. At the follow up, correlation between the change score on the CROM device and the SCT was high (0.86–0.94 depending on the direction of movement). ConclusionThe SCT is a valid, reliable and responsive instrument for measuring cervical ROM.

The validity of a single inertial sensor to assess cervical active range of motion

Cervical active range of motion (AROM) is an important outcome measure for clinicians working with a range of patient populations, especially people with neck pain. Multi-sensor inertial measurement unit (IMU) devices demonstrate good validity in the research laboratory but are expensive and not easily accessible in clinical settings. The use of single-IMU devices has been proposed but their validity for measuring cervical AROM is unknown. A concurrent and content validity study was conducted, comparing accuracy of single-IMU NeckCare Pro™ with multi-IMU Xsens™ for measuring cervical AROM in healthy adults (8 males, 7 females, mean age 30.6 years [SD 10.4]). Cervical AROM was assessed for flexion, extension, rotation (right and left), and lateral flexion (right and left), whereby six repetitions were performed for each movement with the subjects strapped to a high-back chair. Regarding content validity, Xsens™ detected a small amount of thoracic movement that could not be detected by the NeckCare Pro™ during cervical AROM testing, with means ranging from 1.5° to 4.1°. However, this did not significantly impact concurrent validity, which was good for all movements (ICC 0.764 – 0.966). This paper found that single-IMU technology (NeckCare Pro™) had good validity for measuring cervical AROM in healthy adults when subjects were strapped to a chair to limit trunk movement.

Predicting Delayed Concussion Recovery Using Measurements Of Active Cervical Range Of Motion

Intramuscular Electrical Stimulation for the Treatment of Trigger Points in Patients with Chronic Migraine: A Protocol for a Pilot Study Using a Single-Case Experimental Design.

Background and Objectives: Trigger points (TrPs) are prevalent in patients with migraine headaches. Needling interventions targeting TrPs in migraine patients may reduce the intensity and frequency of headaches, yet systematic reviews reveal a lack of robust evidence. Intramuscular electrical stimulation (IMES) is a modality that delivers electrical current into muscles and TrPs, with recent studies suggesting it may amplify the therapeutic effects of dry needling peripherally and centrally. This could be advantageous for patients with migraine and symptomatic TrPs. Materials and Methods: This study will implement a multiple baseline single-case experimental design (SCED). In a clinical setting, a SCED study lends itself to conducting research with only a few patients that each serve as their own controls. In this SCED study, four participants with chronic migraine will be enrolled in a non-concurrent manner and randomized to one of four baseline measurement periods (4, 5, 6 or 7 weeks), leading to four potentially different start dates for each participant in the intervention phase. During the intervention phase, patients will receive five sessions of dry needling with IMES, one session per week for five weeks. The primary outcome measure will be headache frequency, i.e., the reduction in the number of headache days over a one-month period using electronic headache diary data from the Migraine Buddy smartphone application. Secondary outcome measures will be changes in mean migraine pain intensity using a numeric pain rating scale (NPRS), migraine disability using the Migraine Disability Assessment Test (MIDAS), the Headache Impact Test (HIT-6), and changes in selected cervical musculoskeletal impairments including pressure pain thresholds (PPTs) over TrPs, the craniocervical flexion test (CCFT), and cervical active range of motion (AROM). Primary and secondary outcome measures will be analyzed separately using both visual and statistical analyses. Results: Actively recruiting participants. This project was approved by the Mass General Brigham Institutional Review Board (protocol #2023P000931) and is registered with ClinicalTrials.gov (NCT05893914). Conclusions: This study will seek to determine the effects of a five-week intervention period of IMES to TrPs in the posterior cervical muscles of subjects with chronic migraine.

A Prospective Cohort Study on Risk Factors for Cervico-Thoracic Pain in Military Aircrew.

BACKGROUND: Military aircrew frequently report cervico-thoracic pain and injury. The relationship between risk factors and future pain episodes is, however, uncertain. The aim of this study was to identify risk factors for cervico-thoracic pain and to determine the 1-yr cumulative incidence of such pain.METHODS: A total of 47 Swedish aircrew (fighter and helicopter pilots and rear crew) without pain in the cervico-thoracic region were surveyed about work-related and personal factors and pain prevalence using the Musculoskeletal Screening Protocol questionnaire. They also performed tests of movement control, active cervical range of motion, and isometric neck muscle strength and endurance. Aircrew were followed for a year with questionnaires. Logistic regressions were used to identify potential risk factors for future cervico-thoracic pain.RESULTS: Previous cervico-thoracic pain (OR: 22.39, CI: 1.79-280.63), lower cervical flexion range of motion (OR: 0.78, CI: 0.64-0.96), and lower neck flexor muscular endurance (OR: 0.91, CI: 0.83-0.99) were identified as risk factors for reporting cervico-thoracic pain. At follow-up, 23.4% (CI: 13.6-37.2) had reported cervico-thoracic pain during the 12-mo follow-up period.DISCUSSION: The Musculoskeletal Screening Protocol can identify risk factors for cervico-thoracic pain. The link between cervico-thoracic pain and previous pain, as well as lower performance of neck range of motion and muscular endurance, highlights the need for primary and secondary preventive action. The findings from this study can facilitate the development of such pain prevention programs for aircrew.Tegern M, Aasa U, Larsson H.

Immediate effect of craniocervical flexion exercise and Mulligan mobilisation in patients with mechanical neck pain- A randomised clinical trial.

Mechanical neck pain (MNP) is one of the most prevalent musculoskeletal pathologies in the present time. Physiotherapy management strategies comprising manual therapy and exercise therapy are routinely administered in patients with MNP. To compare the immediate effect of craniocervical flexion (CCF) exercise and Mulligan mobilisation on pain, active cervical range of motion (CROM) and CCF test performance in patients with MNP. This prospective, randomised, single-blinded study involved 26 patients with MNP (16 females; mean age; years) randomised to a single session of active CCF exercise (3 sets of 10 repetitions) or Mulligan mobilisation (3 sets of 6-10 repetitions). Pain intensity was measured on a numerical pain rating scale (NPRS), active CROM was measured using CROM device, and CCF test performance with surface electromyography (EMG) from bilateral sternocleidomastoid (SCM) and anterior scalene (AS) muscles recorded pre- and immediately post-intervention by an assessor blinded to the treatment groups. Mann-Whitney U test was used to analyse between groups and Wilcoxon signed rank test was used to analyse within-group significance for pain and CROM, Cochran-Mantel-Haenszel correlation test was used to analyse the CCF test performance on EMG from the bilateral SCM and AS muscles. Comparison between pre- and post-intervention readings revealed statistically significant within-group () and no between-group significant difference for pain, ROM, and CCF test performance, indicating both interventions were equally effective. Patients with MNP who received active CCF exercise or Mulligan mobilisation exhibited similar reduction in pain intensity and increased CROM and CCF test performance post-intervention. Surprisingly, AS surface EMG amplitudes were increased post-intervention in both groups warranting further exploration of its role in neck pain.

Cervical Range of Motion Analysis Performed with an Accelerometer: A Study of Intersession Reliability for Dental Practice.

During the clinical examination of subjects with temporomandibular disorders (TMDs), the dentist sometimes must evaluate the cervical spine, due to the anatomical and functional connections between the cervical portion of the spine and the stomatognathic apparatus. The accelerometer is a device that evaluates the Range of Motion (ROM) of the main movements of the head on the neck. To date, only a few studies have investigated the repeatability of the use of the accelerometer in the assessment of cervical ROM. Therefore, the present longitudinal observational study analyzed the repeatability of acquired cervical movements on a sample of volunteer subjects who underwent accelerometer testing. A sample of 32 subjects was tested twice within 14 days to assess cervical ROM using a standardized protocol based on a review of existing literature. The results show that the examination is reliable for all the positions of the jaw, except for the parameters regarding the asymmetries of rotation and bending. In conclusion, the accelerometer can be considered a reliable tool for evaluating the active cervical ROM. However, further studies will be necessary to make better evaluations.

Profiling migraine patients according to clinical and psychophysical characteristics: a cluster analysis approach.

This study aims to profile migraine patients according clinical and psychophysical characteristics. In this observational study, two cohorts of migraine patients(episodic/chronic) were included. Cohort-1: ictal/perictal phase; Cohort-2: interictal phase.The following variables were assessed: headache frequency; disability; cervical active range of motion(AROM) in flexion, extension, right/left lateral flexion, right/left rotation; pressure-pain threshold(PPT) over: temporalis, two cervical areas(C1/C4 vertebral segments), and two distal pain-free areas(hand/leg). Cluster analysis was performed using the K-means algorithm. Differences across clusters were investigated. Cohort-1: 100 patients were included and two clusters were identified. Cluster-1.1(19%), Cluster-1.2(81%). Cluster 1.1 had a higher percentage of men(p = 0.037) and higher disability(p = 0.003) compared to Clusters 1.2. Cluster 1.2 had reduced AROM in flexion, extension, and left/right lateral flexion(p < 0.037), and lower PPT value in all areas(p < 0.001) compared to Cluster 1.1. Cohort-2: 98 patients were included and three clusters were identified. Cluster-2.1(18%), Cluster-2.2(45%), and Cluster-2.3(37%). Cluster-2.1 had a higher percentage of men compared to clusters-2.2 and 2.3(p = 0.009). Cluster-2.3 had higher headache frequency, and disability compared to Cluster-2.2(p < 0.006), and higher disability compared to Cluster-2.1(p = 0.010). Cluster-2.3 had reduced AROM in all directions compared to Clusters-2.1 and 2.2(p < 0.029). Clusters-2.2 and 2.3 have lower PPT values in all areas compared to Cluster-1.1(p < 0.001). In the Ictal/perictal phase, two clusters were identified according to clinical and psychophysical characteristics, with one group showing no psychophysical impairment and one with increased pain-sensitivity and cervical musculoskeletal-dysfunctions.In the interictal phase, three clusters could be identified, with one group showing no psychophysical impairment, one increased pain-sensitivity, and one increased pain sensitivity and cervical musculoskeletal-dysfunctions.

Concurrent validity of palpation and musculoskeletal ultrasound in evaluating the fascia of individuals with and without myofascial pain syndrome

Background and PurposePalpation evaluates the fascia, a three-dimensional web of connective tissues. We propose altered fascia system displacement in patients with myofascial pain syndrome. This study determined the concurrent validity of palpation and musculoskeletal ultrasound (MSUS) videos played on Windows Media Player 10 (WMP) when evaluating the direction of the fascia system's displacement at the end of the cervical active range of motion (AROM). MethodsThis cross-sectional study used palpation as index test and MSUS videos on WMP as reference test. First, three physical therapists palpated right and left shoulders for each cervical AROM. Second, during cervical AROM, PT-Sonographer recorded the fascia system displacement. Third, using the WMP, the physical therapists evaluated the direction of skin, superficial and deep fascia displacements at the end of cervical AROM. MedCalc Version 19.5.3 determined the "exact" Clopper-Pearson Interval (CPI). ResultsWe found strong accuracy between palpation and MSUS videos on WMP when determining the direction of skin displacement during cervical flexion and extension (CPI= 78.56 to 96.89). There was moderate agreement between palpation and MSUS videos on WMP when determining the direction of the skin, superficial fascia, and deep fascia displacements during cervical lateral flexion and rotation (CPI= 42.25 to 64.13). ConclusionSkin palpation during cervical flexion and extension may be useful in evaluating patients with myofascial pain syndrome (MPS). It is unclear what fascia system was evaluated when shoulders were palpated at the end of cervical lateral flexion and rotation. Palpation as diagnostic tool for MPS was not investigated.

Variability of Active Cervical Range of Motion Within and Between Days in Healthy Participants: A Prospective Observational Study

ObjectiveThe purpose of this study was to determine the intraday and interday variability and systematic change over the day of active cervical range of motion (aCROM) measurements in asymptomatic persons using a clinically applicable measurement device. MethodsA prospective observational study was performed. Sixteen adults (8 men and 8 women, median age 51 years) without neck pain in the last 3 months were recruited in 2 physiotherapy practices. Active cervical range of motion was estimated using the Apple iPhone application “3D Range of Motion.” Measurements were performed 3 times a day for 7 days and spread over a period of 3 weeks. Mean values of aCROM were calculated. Intraday and interday variability was estimated by calculating limits of agreement. ResultsThe limits of agreement for intraday variability ranged from ±12.1° for left rotation to ±15.5° for total rotation. For interday variability, the limits of agreement ranged from ±14.2° for right rotation to ±20.1° for total rotation. No systematic change over the day was found. ConclusionThis study showed substantial intraday and interday variability of aCROM measurements in asymptomatic people. No trend toward an increased or decreased aCROM was observed during the course of the day. When interpreting aCROM values, clinicians should consider the degree of variation in aCROM measurements over time.

Anterior cervical discectomy and fusion, open-door laminoplasty, or laminectomy with fusion: Which is the better treatment for four-level cervical spondylotic myelopathy?

Four-level cervical spondylotic myelopathy (CSM) is a common disease affecting a large number of people, with the optimal surgical strategy remaining controversial. This study compared the clinical outcomes, radiological parameters, and postoperative complications of primarily performed surgical procedures such as anterior cervical discectomy and fusion (ACDF), open-door laminoplasty (LAMP), and laminectomy with fusion (LF) in treating four-level CSM. A total of 116 patients who received ACDF (38 cases), LAMP (45 cases), and LF (33 cases) were followed up for a minimum of 24 months were enrolled in this study and retrospectively analyzed. Clinical outcomes were evaluated using the Japanese Orthopedic Association (JOA) scoring system, the Neck Disability Index (NDI), and the Visual Analogue Scale (VAS). Changes in the curvature of the cervical spine were determined using the cervical curvature index (CCI) and the C2-C7 Cobb angle. Cervical mobility was evaluated using the C2-C7 range of motion (ROM) and active cervical ROM (aROM). Complications were recorded and compared among the three groups. All patients achieved significant improvement in JOA, NDI, and VAS scores at the final follow-up (P < 0.05), whereas no remarkable difference was found among the groups (P > 0.05). In addition, both C2-7 ROM and aROM were significantly reduced in the three groups and LAMP showed the least reduction relatively. As for complications, LAMP showed the lowest overall incidence of postoperative complications, and patients in the ACDF group were more susceptible to dysphagia, pseudoarthrosis than LAMP and LF. Considering improvements in clinical symptoms and neurological function, no remarkable difference was found among the groups. Nevertheless, LAMP had advantages over the other two surgical procedures in terms of preserving cervical mobility and reducing postoperative complications.

The effects of myofascial induction therapy in survivors of head and neck cancer: a randomized, controlled clinical trial

PurposeWe aim to evaluate the effects of myofascial induction therapy (MIT) on the sequelae suffered by the survivors of HNC (sHNC).MethodsWe enrolled 46 sHNC in a randomized controlled trial (RCT), of whom 20 received a MIT protocol and 23 were placed on a waitlist while receiving the recommended treatment for 6 weeks. The MIT protocol included a total of 18 sessions, 3 days a week on alternate days for 6 weeks. Maximal mouth opening, the presence of temporomandibular dysfunction, cervical endurance, active range of motion (AROM), shoulder AROM, handgrip strength, and perceived physical fitness were assessed.ResultsMaximal mouth opening, temporomandibular dysfunction, cervical endurance, and AROM, affected shoulder abduction and unaffected shoulder flexion and external rotation significantly improved (p < .05) after an MIT protocol, but only cervical AROM and affected shoulder abduction changes were clinically meaningful. No statistically significant changes were observed in the other shoulder AROM, handgrip strength, or physical fitness perception (p > .05).ConclusionA 6-week MIT protocol improves mouth opening, TMD, cervical function (endurance and AROM), affected shoulder abduction and unaffected shoulder flexion, and external rotation AROM in the sHNC. However, no changes were observed in most of the shoulder AROM, muscular strength, or perceived physical fitness. Future studies should perform longer follow-up designs, increase the sample size, and include multimodal treatments to address these sequelae in the sHNC.

Effects of breathing reeducation on cervical and pulmonary outcomes in patients with non specific chronic neck pain: A double blind randomized controlled trial.

ObjectiveThe purpose of this randomized controlled trial was to study effects of breathing reeducation in the treatment of patients with non specific chronic neck pain.MethodsA total of sixty eight eligible patients with chronic neck pain were randomly allocated to breathing reeducation (BR) group (n = 34) and routine physical therapy (RPT) group (n = 34). Clinical outcomes were neck pain measured through visual analogue score, cervical active range of motion through CROM device, strength of neck muscles through hand held dynamometer and endurance of neck muscles measured through craniocervical flexion test. The neck disability was measured through neck disability index (NDI) and pulmonary outcomes such as forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC ratio were measured through Spirolab 4. The outcomes were assessed at baseline and at 4 and at 8 weeks from baseline.ResultsThere were significant improvements in the BR group compared with the RPT group (P = 0.002) for cervical flexion, extension (P = 0.029), endurance (P = 0.042), strength of neck flexors (P <0.001), neck extensors (P = 0.034). Likewise there was a significant change in NDI (P = 0.011), FEV1 (P = 0.045), FVC (P <0.001), and FEV1/FVC ratio (P <0.001) in the BR group compared with the RPT group. The cervical side flexion and rotation showed no significant difference in breathing reeducation group with p > 0.05.ConclusionBreathing reeducation combined with routine physical therapy is an effective treatment in patients with non specific chronic neck pain.Trial registrationIRCT 20200226046623N1, https://www.irct.ir/trial/46240.

The efficacy and safety of non-resistance manual therapy in inpatients with acute neck pain caused by traffic accidents: A randomized controlled trial.

Background:Neck pain and functional impairment are common complications of traffic accidents (TAs); however, the effects of manual therapy on these symptoms have rarely been studied in the literature. Thus, this randomized controlled trial aims to assess the effectiveness and safety of non-resistance manual therapy (NRT)—a treatment combining mobilization and pressure release techniques—on acute neck pain caused by TA.Method:This study will use a two-armed, parallel, assessor-blinded randomized controlled trial design and will be conducted in the Daejeon Jaseng Hospital of Korean Medicine in South Korea. One hundred twenty patients will be recruited and randomized into an integrative Korean medicine treatment (IMKT) + NRT group and IMKT group in a 1:1 ratio. The primary outcome is a change in the numeric rating scale for neck pain immediately after treatment on hospital day 5 compared to those at baseline. The secondary outcomes are numeric rating scale for radiating arm pain, visual analogue scale for neck pain and radiating arm pain, cervical active range of motion, neck disability index, Patient Global Impression of Change, Short Form-12 Health Survey, and Posttraumatic Stress Disorder Checklist for DSM-5.Discussion:The findings of this study on the effectiveness and safety of NRT will be helpful for patients with TA-induced neck pain in clinical practice and will provide evidence for developing relevant healthcare-related policies.Trial registration:This protocol has been registered at Clinicaltrials.gov (NCT04660175).

Effects of active scapular correction on cervical range of motion, pain, and pressure pain threshold in patients with chronic neck pain and depressed scapula: a randomized controlled trial

ABSTRACT Background Correction of scapular alignment is advocated as a component for alleviating symptoms for patients with neck pain. Objective The study aimed to examine the effect of active scapular correction on cervical range of motion (ROM), pain, and pressure pain threshold (PPT) in patients with chronic neck pain with depressed scapula. Methods A randomized control trial research design was conducted. Twenty-eight participants with chronic neck pain and depressed scapula were randomly assigned to either the intervention (n = 14) or control (n = 14) group. Active cervical rotation ROM, pain at maximum cervical rotation, and PPT over the upper trapezius muscle region were measured at baseline and post active scapular correction. Results The participants in the intervention group showed significantly greater active cervical rotation ROM and less pain at maximum cervical rotation than the control group, both on the ipsilateral (p < 0.01) and contralateral (p < 0.05) sides of the depressed scapula. No significant difference in PPT between the groups was demonstrated (p = 0.194). Conclusion Active scapular correction intervention resulted in an immediate increase in active cervical rotation ROM and a decrease in neck pain at maximum cervical rotation.
