Objectives The purpose of this study is to assess the effectiveness of Chuna manual therapy for shoulder pain in hemiplegic patients after stroke. Methods For a systematic review and meta-analysis, we set a key question in accordance with participants, intervention, comparison, outcome, study design (PICO-SD). we searched for clinical studies that conducted chuna manual therapy for shoulder pain in hemiplegic patients after stroke 7 databases until September 2019. Only randomized controlled trials were chosen. Results Total 14 randomized controlled trials were chosen for systematic review and meta-analysis. 9 studies used efficacy rate as evaluation tool, and 8 used visual analogue scale. Pressure method (壓力型) was used in 11 studies, followed by osteopathy method (整骨型) and wave motion method (波動型) in 9 studies. Chuna manual therapy showed statistically significant pain reduction effect. Through meta analysis, Chuna manual therapy showed significant pain reducing effect except the study with Chuna manual therapy and electroacupuncture compared to electroacupuncture only. Conclusion As a result, Chuna manual therapy showed statistically significant effect in pain reduction. However, almost studies were evaluated in a state of having probable high risk of bias. This suggests that it requires attention to make an interpretation in this study. Furthermore, more clinical research need to be accomplished in the future.

This work intends to investigate the effects of shift characteristics on the propulsion performance of a manual wheelchair with an automatic transmission. A planetary gear train is employed to generate a two-stage shift automatically, based on the distance traveled from rest. Motion analysis has been performed for measuring kinematic properties of the arm and then the inverse dynamics has been applied for estimating joint forces/torques. Then, a parametric study has been performed to find a set of the shift ratios and the shift intervals for optimizing propulsion performance. Results show that the propulsion performance is closely related to the shift condition. It is found that a short shift interval is desirable for a short distance propulsion. However, an optimum shift interval for a long distance propulsion is inversely proportional to the shift ratio approximately. Consequently, the automatic transmission can greatly lower the joint loadings by the speed reduction, which eventually contribute to prevent joint injuries of wheelchair users.

Objective: Axillary web syndrome (AWS) is a condition comprising fibrous band-like cords that appear in the axilla of patients after axillary lymph node dissection (ALND) during breast cancer surgery and result in pain and reduced mobility. The cords appearing with AWS are hardened veins or lymphatic vessels. Manual therapy and stretching are recommended for pain control and mobility improvement. Therefore, this study investigated the effect of cytoskeletal manual therapy (CMT), which is a new soft tissue mobilization technique. Design: A case report Methods: A 41-year-old woman with AWS after breast cancer surgery and ALND visited a physical therapy clinic because of shoulder pain, decreased function, and decreased mobility. The cords were palpable and pain occurred 2 weeks after surgery. CMT was performed three times per week for a total of 6 weeks. Her pain intensity, range of motion (ROM), and shoulder function were measured. Results: Measurements were performed after 2 weeks and 6 weeks of CMT and evaluated using the numeric pain rating scale (NPRS). Her pain intensity largely decreased after 2 weeks (4-point score reduction) and after 6 weeks (5-point score reduction) of CMT. After CMT, her full ROM was restored and her shoulder function was improved (7-point score reduction). Conclusions: CMT is effective for pain control, mobility improvement, and functional improvement of patients with AWS.

Objective: Manual therapy is a commonly utilized approach in managing chronic pain, but its specific impact on pain catastrophizing remains uncertain. The objective of this systematic review and meta-analysis was to examine the effects of manual therapy on pain catastrophizing in individuals with chronic pain. Design: A systematic review and meta-analysis Methods: A comprehensive search was conducted in electronic databases to identify relevant studies published from 2014 onwards. Studies that evaluated the impact of manual therapy on pain catastrophizing in individuals with chronic pain were incorporated. The risk of bias in the selected studies was evaluated using the Cochrane tool for risk of bias in qualitative analysis. For the quantitative analysis, RevMan 5.4 software was utilized, employing a random-effects model as the analysis model. The effect measure used in the analysis was the standardized mean difference (SMD). Results: In total, 26 studies were collected, and following the screening process, three of them were incorporated into the final analysis. The included studies involved a total of 153 patients with chronic pain. The interventions comprised various manual therapy techniques targeting different areas of the body. Pain catastrophizing and pain intensity were the primary outcomes of interest. The meta-analysis revealed a significant reduction in pain catastrophizing scores following manual therapy intervention compared to control conditions (SMD = -0.91, 95% CI: -1.25 to -0.58). However, heterogeneity between the studies was observed. Conclusions: Despite the limited quantity and heterogeneity of studies, it has been demonstrated that manual therapy intervention is effective in reducing pain catastrophizing in individuals with chronic pain.

Objectives This study aimed to explore literature evidence regarding Chuna manual therapy for premature infants and determine its applicability. Methods Eight electronic databases were searched, and randomized control trials (RCTs) applying Chuna manual therapy to premature infants were sought. The Cochrane risk of bias tool was employed to assess the methodological quality of each RCT. Results Two RCTs met the inclusion criteria and were subjected to analysis. Each study compared the usual care group with the pediatric Chuna group. The results indicated improvements in nutritional status, a reduction in hospitalization days, and enhancements in growth indicators. Conclusions Chuna manual therapy is worth applying to premature infants. However, evidence is limited due to a lack of well-designed RCTs. More qualified clinical trials are needed to obtain stronger evidence.

Objective : The purpose of this study was to evaluate the efficacy of the anterior approach following intraoperative reduction under general anesthesia in patients with cervical facet fracture and dislocation. Methods : Twenty-three patients with single level cervical facet fracture and dislocation who were subjected to the anterior approach alone following immediate intraoperative reduction under general anesthesia from March 2013 to December 2017 were enrolled in this study. Neurological status, clinical outcome, and radiological studies were evaluated preoperatively, postoperatively, and during the follow-up period. Results : The cohort comprised 15 men and eight women with a mean age of 57 years (from 24 to 81). All patients were operated on within the first 8 hours following the injury. After gentle manual reduction or closed reduction with Gardner-Wells traction, under general anesthesia monitored by somatosensory-evoked potentials, all operations were successfully completed using the anterior approach alone except in two patients, who had a risk of over-distraction. In them, a satisfactory gentle manual reduction or closed reduction was not possible, and required open posterior reduction of the locked facets followed by anterior cervical discectomy and fusion. In one patient, screw retropulsion was observed in 1 month after surgery. There were no reduction-related complications or neurological aggravations after surgery. All patients showed evidence of stability at the instrumented level at the final follow-up (mean follow-up, 12 months). Conclusion : Anterior approach following intraoperative reduction monitored by somatosensory-evoked potentials under general anesthesia for cervical dislocation and locked facets is a relatively safe and effective alternative when cervical alignment is achieved by intraoperative reduction.

Objective : Unilateral facet dislocation of the cervical spine occurs by flexion and rotation injuries and cannot be easily reduced by axial traction. We analyzed 14 consecutive patients with unilateral facet dislocation of the cervical spine to increase knowledge about anatomical reduction of locked facet and factors for successful reduction. Methods : Fourteen patients [10 men and 4 women] with unilateral facet dislocation of the cervical spine were retrospectively analyzed. Plain X-ray, computerized tomography scan, and magnetic resonance imaging were performed. All patients underwent manual reduction and surgery with anterior interbody fusion and plate fixation. The manual reduction was performed by neck flexion and rotation to the opposite side of dislocation, followed by rotation and flexion of the head toward the side of dislocation and extension with relaxation of traction. Mean follow-up period was 17 months. The level of spine, amount of subluxation, combined facet fracture, and time from injury to initial reduction were analyzed using the data obtained from medical records. Results : Thirteen [93%] patients were reduced successfully. Immediate reduction was achieved in 7 patients but failed in 7 patients. Seven patients underwent delayed closed reduction under general anesthesia, and successful reduction was achieved in 6 patients. Only one patient with bone chips between articular facets failed to achieve anatomical reduction. Conclusion : In order to reduce the locked facet more easily and safely, we recommend manipulative traction with anterior interbody fusion and plate fixation under general anesthesia after being aware of spinal cord injury with magnetic resonance imaging.

Objectives This study aimed to evaluate the efficacy of Chuna manual therapy(CMT) in the treatment of rotator cuff disorder. Methods We searched th following nine online databases without language restriction (MEDLINE/PubMed, Cochrane library, Ebscohost, CNKI, RISS, NDSL, KMBASE, and KISS) to identify randomized controlled trials (RCTs) that used CMT in the treatment of rotator cuff disorder. The methodological quality of each RCT was assessed using the Cochrane risk-of-bias tool. Results Four RCTs were included. in the meta-analysis. CMT resulted in a significant reduction in symptoms in these trials. However, there was a high risk of bias in the RCTs. Conclusions We reviewed RCTs that studied the effects of CMT for rotator cuff disorder. While the studies indicate that CMT has favorable effects on rotator cuff disorder. But the risk of bias for most of the studies was high. Therefore, high-quality studies are required to make further conclusions.
