Objective
The purpose of this study was to investigate the effects of thoracic spine angle during trunk rotation on the relative rotation angles of the lumbar and pelvic regions, as well as coupled motions.
Methods
Twenty-two young asymptomatic volunteers stood in a comfortable upright posture for 5 seconds, with inertial measurement units attached at the T1, T7, T12, L3, and S2 levels. Participants were divided into kyphotic thoracic (40° ≤ T1–T12 < 50°) and normal thoracic (40° < T1–T12) groups based on measurements taken during standing. Participants performed trunk axial rotation while sitting, and the Eulerian angles were measured at the T1, T7, T12, L3, L5, and S2 levels.
Results
The rotation angles at the T1 (right side, P = .023; left side, P = .035) and S2 (right side, P = .037; left side, P = .015) levels were greater in the kyphotic thoracic compared to the normal thoracic group.
Conclusions
In asymptomatic participants with slight thoracic kyphosis, trunk axial rotation was affected by thoracic curvature.

Objective
The Cartesian Optoelectronic Dynamic Anthropometer (CODA) motion analysis system is a new instrument that measures 3-dimensional joint movement. The study aimed to investigate the reliability and validity of the CODA motion analysis system in assessing the cervical range of motion in healthy people.
Methods
A total of 41 healthy participants were included. Movements in 3 planes (flexion and extension, right and left lateral bending, and right and left axial rotation) were measured by using the CODA motion analysis system. The results for flexion–extension and lateral bending movements were compared with those obtained by a standard inclinometer. Intraobserver and interobserver reliability and validity were assessed using the intraclass correlation coefficient (ICC) method. SE of measurement (SEM) and minimal detectable change (MDC) values were also calculated to identify the measurement errors.
Results
High interobserver reliability (ICC range, 0.89-0.94) and validity (ICC range, 0.73-0.89) were found for all 3 planes, while the intraobserver reliability (ICC range, 0.76-0.92) was high, except for right lateral bending (ICC, 0.76) and left axial rotation movements (ICC, 0.84). All SEM and MDC values for intraobserver, interobserver, and criterion validity studies were less than 5° and 10°, respectively. Percentage of SEM of ≤10% and percentage of MDC of ≤30% were obtained for all variables.
Conclusion
The CODA motion analysis system is a highly reliable, noninvasive, easy-to-use, and reproducible 3-dimensional device for measuring cervical range of motion. It demonstrated good reliability for flexion–extension and lateral bending movements.

Objective
The purpose of this study was to investigate the effect of local vibration therapy on the activation of the extracellular signal-regulated kinase (ERK1/2) signaling pathway and the proliferation of Schwann cell with the goal of promoting remyelination after sciatic nerve injury (SNI).
Methods
Experimental Sprague Dawley rats were divided into the sham group, SNI group, vibration group, and U0126 inhibitor group, with 8 rats in each group. The rats in the vibration and U0126 inhibitor groups received local vibration intervention for 21 consecutive days from the 7th day after operation. We used the sciatic nerve functional index to assess behavioral recovery in rats and performed immunofluorescence staining and Western blotting to assess the effects of SC proliferation and expression of myelin protein in the injured sciatic nerve.
Results
The sciatic nerve functional index of rats in the vibration group was significantly increased on the 21st and 28th day after surgery compared to that of those the SNI group; on the 28th day after injury, p-ERK1/2 was significantly activated and Schwann cell proliferation was induced in the vibration group, but U0126 inhibitor group showed no significant difference effect in Schwann cell proliferation. The expression of myelin basic protein secreted by Schwann cell was significantly upregulated in the vibration group compared to the SNI group, but myelin basic protein expression was not significantly different in the U0126 group.
Conclusion
The results showed that local vibration therapy after SNI accelerated Schwann cell proliferation through activation of the ERK1/2 signaling pathway, and effectively promoted myelin repair in a rat model.

Objective
The purpose of this observational study was to examine whether limited ankle dorsiflexion (LAD) affects the kinematic parameters of the lower limb joints and trunk during a bilateral squat.
Methods
Forty-four physically active and non-injured participants, with limited ankle dorsiflexion (DF) < 30° (n = 18) and without limitations, DF > 35° (n = 26) during the weight-bearing lunge test, were recruited. The angles and ranges of motion (ROM) of lower limb joints, pelvis and spine were recorded using a 3D motion capture system.
Results
Participants with LAD had a greater pelvis ROM in the sagittal plane (P = .001), a greater hip and lumbar spine flexion ROM (P = .002; P = .01, respectively) and a greater trunk forward lean (P < .001) during squatting compared to the control group. In the LAD group, ankle DF during squatting correlated with trunk lean (r = −0.49, P = .04), while in the control group, it correlated with spine mobility (r = 0.44, P = .03).
Conclusions
The findings suggest that the pelvis and trunk forward lean have a regulatory role in response to LAD during squatting.
目的：本观察性研究的目的是研究双侧深蹲时有限的踝关节背屈（LAD）是否会影响下肢关节和躯干的运动学参数。方法：招募44名在负重弓步试验中踝关节背屈(DF) < 30°（n = 18）和踝关节背屈(DF) < 35°（n = 26）且身体活动且未受伤的参与者。使用三维运动捕捉系统记录下肢关节、骨盆和脊柱的角度和活动范围。结果：与对照组相比，LAD参与者在矢状面有更大的骨盆ROM (P = 0.001)，髋关节和腰椎屈曲ROM （P = 0.002; P = 0.01）和蹲坐时躯干前倾更大（P < 0.001）。LAD组下蹲时踝关节DF与躯干倾度相关（r = -0.49, P = 0.04），对照组下蹲时踝关节DF与脊柱活动度相关（r = 0.44, P = 0.03）。结论：研究结果表明，骨盆和躯干前倾在深蹲时对LAD有调节作用。

Objective
This study aimed to compare the effects of 3 hip abduction exercises in the side-lying position on electromyography activities of the lumbopelvic muscles in young females with weak hip abductor.
Methods
Twenty-one females with weakness of the gluteus medius (GMed) volunteered for this study. Participants performed the 3 exercises in side-lying position: (1) side-lying hip abduction exercise, (2) clam exercise, and (3) side-bridge exercise. Surface electromyography data were collected from the GMed, quadratus lumborum (QL), gluteus maximus, and tensor fascia latae.
Results
The clam exercise showed significantly less active for the GMed (25.67 ± 13.78% maximal voluntary isometric contraction [MVIC]) and QL (31.29 ± 20.69%MVIC) compared to side-lying hip abduction exercise (GMed: 54.38 ± 18.61%MVIC and QL: 79.90 ± 36.96%MVIC) and side-bridge exercise (GMed: 66.67 ± 39.50%MVIC and QL: 121.62 ± 31.72%MVIC) (P < .05). Side-lying hip abduction exercise showed significantly less active QL compared to side-bridge exercise (P < .05). Furthermore, the GMed/QL ratio was significantly lower for the side-bridge exercise than for the other 2 exercises (P < .05).
Conclusion
These findings indicate that side-lying hip abduction exercise and clam exercise may be beneficial to facilitate the efficient use of lumbopelvic muscles. In addition, the activity of the GMed during side-lying hip abduction exercise seems to be more acceptable for strengthening.

Objective
The purpose of this study was to analyze hip, shoulder, and elbow movements of a doctor of chiropractic during performance of side-posture chiropractic spinal manipulation.
Methods
An experienced chiropractor performed lumbar spinal manipulation (ie, chiropractic adjustment) on 10 participants. An inertial measurement unit system was used to record angular motions, and data were analyzed in Excel to identify positional angles at set-up and thrust times, and to generate graphs of time series plots for qualitative assessment of movement patterns.
Results
Most motion patterns were qualitatively similar between participants for each joint and plane of motion, though angular magnitudes were often different; but times of thrust were not consistent within the patterns. Positional angles for the left and right shoulders were asymmetrical, as were those for the left and right hips, reflecting their different roles in patient stabilization and thrust. The right elbow displayed only a few degrees of extension during the thrust, reflecting its role in transferring the force from the chiropractor’s center of gravity (“body drop”), rather than the upper extremity solely generating the thrust.
Conclusions
Most motions had thrust-to-thrust consistency in their patterns, despite trial-to-trial differences in angular magnitudes, suggesting that a DC’s performance is repeatable for spinal manipulation. Measurements might be different for other DCs according to differences in professional education, treatment tables of different heights, or patients with different body sizes.

Objective
The purpose of this study was to assess (1) intrarater reliability of cervical rotation in the transverse plane (CRTP) range of motion (ROM) in the cervical neutral position and at the end-ROM right cervical lateral flexion position using computed tomography (CT) scans and (2) segmental (C0-C7) CRTP ROM in cervical neutral and end-ROM cervical lateral flexion positions to determine whether CRTP in prepositioned cervical lateral flexion mainly assesses C1-C2 mobility.
Methods
In this cadaveric investigation, Thiel-embalmed cadaveric specimens were used to assess (1) intrarater reliability of C1-C2 segmental CRTP in neutral and end-ROM cervical lateral flexion positions using CT scans and (2) total available CRTP and cervical segmental contribution in cervical neutral and end-ROM cervical lateral flexion prepositions.
Results
Ten cadavers aged 80.8 ± 12.2 years were used. CT scan measurements showed high intrarater reliability with an intraclass correlation coefficient (3,1) ≥0.99. End-ROM cervical lateral flexion prepositioning decreased the total available CRTP by 44% compared with CRTP in a neutral position (P ≤ .01). In end-ROM cervical lateral flexion prepositioning, 89% of the total available CRTP occurred at C1-C2, 10% at C0-C1, and only 1% at C2-C7. Hence, cervical lateral flexion prepositioning almost excluded all cervical disc segments for CRTP.
Conclusions
Cervical lateral flexion prepositioning prioritizes C1-C2 movement assessment during cervical axial rotation by reducing motion in the other cervical segments.

Objective
The purpose of this study was to examine methods of pharmacologic and nonpharmacological pain management for people with bone-related diseases.
Methods
Bone-related disease incidence, treatment, and pain management strategies were assessed using an anonymous online survey in 2021. The survey included questions about demographics, disease characteristics, and pain coping. One-sample χ2 goodness of fit tests, 2-way Pearson χ2 tests of independence, and probability values were used for data analysis.
Results
Respondents were primarily postmenopausal females, aged 55-60 years old, with moderate disease activity, with osteoporosis most commonly reported. Responses suggest medical professionals’ advice for pain management included multiple medications, especially analgesics. Dietary interventions also played an important role with vitamin D and calcium supplementation regularly being reported. Patients seek to use alternative methods of pain relief and disease management, with many respondents reporting nonpharmacological pain relief treatments playing a significant role in coping with their bone disease. Although respondents aged 46 to 50 opted against nonpharmacological relief, those aged 56 to 60 years reported they were willing to try nonpharmacological interventions that reduced pain, with the choice of treatment based on “how it made me feel.”
Conclusion
A substantial number of respondents believed that more research is required into pain relief for bone-related diseases, with those affected by these conditions seeking a more acute and analgesic approach to managing pain. Most respondents answered “yes” when asked if nonpharmacological pain relief treatments play a sufficient role in coping with their bone-related pain.

Objective
The purpose of this study was to establish reference values for the Craniocervical Flexion Test (CCFT) in healthy volunteers and to explore the relationship between age and sex on the CCFT.
Methods
This prospective, observational, cross-sectional study was developed in the assessment room of the Physiotherapy department at the Universitat Internacional de Catalunya. The study included healthy subjects between 18 and 75 years old. CCFT and sociodemographic variables, such as pain or physical activity, were collected. Linear regression models were developed with age and sex as the only predictor variables. Adjusted models were developed factoring in the sociodemographic information.
Results
A total of 122 volunteers (61 males, 61 females) between 18 and 75 years old participated in the study. The mean CCFT for the sample was 25.48 (3.3) mm Hg. Linear regression model by sex showed a coefficient of 1.11 mm Hg (CI 95%: -0.06, 2.29; p = .062) with men demonstrating 1.11 mm Hg more than women. Linear regression models by age strata showed a coefficient of -0.17 mm Hg (CI 95%: -0.51, 0.18 p = .347) for each decade of age. Variables related to sociodemographic information showed no significant effect.
Conclusion
Gender and age have no relationship with the results of CCFT in healthy volunteers. The reference value for the Craniocervical flexion test in 122 healthy adults was 25.48 (3.30) mm Hg. This value may help therapists examine/set goals for patients with head/neck pain.
目的：本研究旨在为健康志愿者的颅颈屈曲试验（CCFT）建立参考值，并探讨年龄和性别对CCFT的影响。方法：这项前瞻性、观察性、横断面研究是在加泰罗尼亚国际大学物理治疗系的评估室进行的。这项研究包括了年龄在18岁到75岁之间的健康受试者。收集CCFT和社会人口学变量，如疼痛或身体活动。建立了以年龄和性别为唯一预测变量的线性回归模型。将社会人口统计信息纳入调整后的模型。结果：共有122名志愿者（男61名，女61名）参加了这项研究，年龄在18至75岁之间。样本的平均CCFT为25.48 (3.3)mm Hg。按性别划分的线性回归模型显示，该系数为1.11 mm Hg (CI 95%: -0.06, 2.29; p = 0.062)，男性比女性多1.11 mm Hg。年龄层线性回归模型显示，每10年的年龄系数为-0.17 mm Hg （CI 95%: -0.51, 0.18 p = .347）。与社会人口统计信息相关的变量无显著影响。结论：性别、年龄与健康志愿者CCFT结果无关。122名健康成人颅颈弯曲试验的参考值为25.48 (3.30)mm Hg。该值可以帮助治疗师检查/设定头颈疼痛患者的目标。

Objectives
The purpose of this study was to assess the association between baseline factors and adherence to rehabilitative home exercise (RHE) after 12 weeks of chiropractic spinal manipulation (CSM) plus RHE instruction, and whether adherence was associated with improvement in back-related disability in adults ≥65 years with chronic low back pain (CLBP).
Methods
This secondary analysis used randomized trial data collected in 2010 through 2013 from community-dwelling older adults with CLBP and disability in a metropolitan area in the upper mid-west United States. We defined adherence as exercising ≥ 4 days/week, and clinically meaningful disability improvement as ≥ 30% reduction in Oswestry Disability Index (ODI). Baseline factors (demographic, low back, activity, function) associated with adherence and change in disability were tested with chi-square and logistic regression.
Results
Among 176 participants, mean age was 71.1 years, 59.7% were female, and median back pain duration was 13.5 years. Baseline average back pain and ODI were moderate. Over 12 weeks of treatment, median CSM visits was 11; RHE instruction was 4. Over half the participants (56.3%) reported RHE adherence of ≥ 4x/week at 12 weeks. No baseline factors were associated with 12-week RHE adherence (all P > .05), and adherence was not associated with change in ODI. Only adherence at 4 weeks was positively associated with 12-week adherence (P < .001).
Conclusions
Among this sample of older adults with CLBP, baseline patient characteristics did not predict adherence to home exercise recommendations. Further, adherence was not associated with clinically meaningful change in disability.
