Post-burn contractures are common entities seen in developing countries. There are multiple reasons for the development of contractures, most are preventable. In extensive contractures, a strategic plan is necessary to release all contractures and yet not antagonize post-operative positions. It is also necessary to be cost-effective and minimize the number of surgeries needed. Conventionally the release sequence in extensive burn contractures is proximal to distal. In this case report, we discuss an unusual sequence where we released distal contractures before the proximal to achieve optimum results. A 3-year-old child with post-burn contracture of hand, wrist, elbow, and axilla was treated in 2 stages, with the release of wrist contracture and cover with pedicled abdominal flap in the first stage and division of pedicled flap with the release of axilla and elbow contracture in the second stage. Thus, the release of all contractures was achieved without antagonizing post-operative positions and minimized the number of surgeries. A case-based approach may be crucial in making a strategic surgical plan to minimize the rehabilitation phase, rather than following known dictums.

PURPOSE: Upper limb disorders are one of the most common and important types of occupational injuries. Besides, identifying the factors influencing return to work following these injuries is essential to reduce the dimensions of the problem. In this study, we investigated the return to work and associated factors following occupational injuries leading to upper limb impairment. METHODS: In this retrospective cohort study, the rate of return to work and associated factors were assessed in 256 workers with work-related upper limb injury referred to a teaching hospital from March 2011 to December 2018. The inclusion criterion was a history of occupational injury resulting in upper limb impairment, and exclusion criteria included the presence of simultaneous impairment in other organs, congenital or non-occupational limb defects as well as patients with incomplete information in their medical records. Individuals' records, including age at the time of injury, gender, date of injury, marital status, education, level of amputation and injury, whole person impairment (WPI) and physiotherapy (prescribed by the physician) were reviewed. The WPI was calculated to assess the extent of the injury. All analyzes were performed by SPSS version 25.0. RESULT: The rate of return to work was 54.3%, in which 51.8% for the same job and 48.2% for a new job. The main factors associated with non-return to work were more days off work (p = 0.001), higher injury severity (p = 0.001), and dominant hand injury (p = 0.034). CONCLUSION The number of days off work, the WPI, and dominant hand injury are the most important determinant in returning to work. In addition, increased job satisfaction and support from co-workers and employers are work-related factors that can lead to an increased return to work.

OBJECTIVE: To compare the curative effect between interactive scalp acupuncture and traditional scalp acupuncture on hemiplegic upper extremity motor dysfunction in the patients with ischemic stroke. METHODS: Seventy cases of hemiplegic upper extremity motor dysfunction of ischemic stroke were randomly divided into an interactive scalp acupuncture group (35 cases, 1 case breaked off) and a traditional scalp acupuncture group (35 cases, 1 case dropped off). The patients of the two groups received the secondary prevention medication and routine rehabilitation therapy. Besides, in the interactive scalp acupuncture group, the upper extremity occupational therapy was operated during the needle retaining of scalp acupuncture; and in the traditional scalp acupuncture group, the upper extremity occupational therapy was delivered after the completion of scalp acupuncture. The same points were selected in the two groups such as Fuxiang head area, Fuxiang upper-limb-shoulder point, Fuxiang upper-limb-elbow point and Fuxiang upper-limb-wrist point. The needles were inserted perpendicularly by flying-needle technique and manipulated by triple technique of gentle twisting, heavy pressure and vibrating. The needles were retained for 30 min. Based on the degree of the upper extremity motor impairment, the regimen of the upper extremity occupational therapy was formulated individually and one treatment took 30 min. In the two groups, the therapies were delivered once daily, 5 times a week, lasting 4 weeks. Before and after treatment, the scores of Fugl-Meyer assessment of upper extremity (FMA-UE), Wolf motor function test (WMFT), the modified Barthel index (MBI) and the modified Ashworth scale (MAS) grade in the two groups were observed before and after treatment. RESULTS: After treatment, the scores of FMA-UE, WMFT and MBI were higher than those before treatment (P<0.01), and MAS grade was improved (P<0.05) in the two groups. The scores of FMA-UE, WMFT and MBI in the interactive scalp acupuncture group were higher than those in the traditional scalp acupuncture group (P<0.01, P<0.05), and there was no statistical significance in the difference of MAS grade between the two groups (P>0.05). CONCLUSION The interactive scalp acupuncture can effectively improve the motor function of the hemiplegic upper extremities and the activities of daily living in the patients with ischemic stroke and its efficacy is better than traditional scalp acupuncture. But these two types of scalp acupuncture obtain the similar effect on spasticity.

OBJECTIVE: To observe the clinical efficacy of lidong needling therapy (acupuncture technique combined with therapeutic movement of the body) on upper limb lymphedema after breast cancer surgery in combination with functional exercise. METHODS: A total of 73 patients with postoperative lymphedema of breast cancer in the upper limbs were randomized into an observation group (36 cases) and a control group (37 cases). The routine nursing care and functional exercise were given in the control group, twice a day, for about 10-15 min each time, lasting 8 weeks. On the basis of the treatment as the control group, lidong needling therapy was applied to the acupionts on the affected upper limb, i.e. Jianyu (LI 15), Waiguan (TE 5), Hegu (LI 4) and ashi points (the most obvious swelling sites), as well as to bilateral Yinlingquan (SP 9) and Zusanli (ST 36), etc. The needles were retained for 30 min. While the needles retained, the patients were asked to move the affected shoulder to 90° by the sagittal anteflexion and keep it elevated. Simultaneously, the hand on the affected side was clenched and opened slowly and coordinately. Lidong needling therapy was delivered once every two days, three times weekly for 8 weeks. Before and after treatment, the difference of the circumference between the affected and healthy limbs, the score of visual analogue scale (VAS) for swelling and the score of disability of arm, shoulder and hand (DASH) were compared in the patients of the two groups. The clinical efficacy was evaluated. RESULTS: After 2, 4, 6 and 8 weeks of treatment, except for the circumference of the area 10 cm below the cubitel crease in the control group, the differences in the circumferences of the rest parts between the affected and healthy limbs were reduced in comparison with those before treatment in the two groups (P<0.01, P<0.05). After 6 weeks of treatment, in the observation group, for the circumference at the level of hand between the thumb and the index finger and that of the wrist, the differences between the affected and healthy limbs was smaller compared with those in the control group (P<0.05). After 8 weeks of treatment, except for the areas 5 cm below and above the cubitel crease, the differences of circumferences between the affected and healthy limbs in the observation group were smaller than those in the control group in the rest parts (P<0.01, P<0.05). After 8 weeks of treatment, the swelling VAS scores were reduced when compared with those before treatment in the two groups (P<0.05), and the score in the observation group was lower than that in the control group (P<0.01). After 4 and 8 weeks of treatment, DASH scores were reduced in comparison with those before treatment in the two groups (P<0.01). The total effective rate of the observation group was 83.3% (30/36), which was higher than that of the control group (35.1%, 13/37, P<0.01). CONCLUSION Lidong needling therapy combined with the functional exercise obtains the satisfactory clinical effect on the upper limb lymphedema after breast cancer surgery. This treatment effectively relieves swelling and improves the upper limb function.

OBJECTIVES: To compare the effects of electroacupuncture (EA) with different time intervals on corticospinal excitability of the primary motor cortex (M1) and the upper limb motor function in healthy subjects and observe the after-effect rule of acupuncture. METHODS: Self-comparison before and after intervention design was adopted. Fifteen healthy subjects were included and all of them received three stages of trial observation, namely EA₀ group (received one session of EA), EA_6h group (received two sessions of EA within 1 day, with an interval of 6 h) and EA_48h group (received two sessions of EA within 3 days, with an interval of 48 h). The washout period among stages was 1 week. In each group, the needles were inserted perpendicularly at Hegu (LI 4) on the left side, 23 mm in depth and at a non-acupoint, 0.5 cm nearby to the left side of Hegu (LI 4), separately. Han's acupoint nerve stimulator (HANS-200A) was attached to these two needles, with continuous wave and the frequency of 2 Hz. The stimulation intensity was exerted higher than the exercise threshold (local muscle twitching was visible, and pain was tolerable by healthy subjects, 1-2 mA ). The needles were retained for 30 min. Using the single pulse mode of transcranial magnetic stimulation (TMS) technique, before the first session of EA (T0) and at the moment (T1), in 2 h (T2) and 24 h (T3) after the end of the last session of EA, on the left first dorsal interosseous muscle, the amplitude, latency (LAT), resting motor threshold (rMT) of motor evoked potentials (MEPs) and the completion time of grooved pegboard test (GPT) were detected. Besides, in the EA_6h group, TMS was adopted to detect the excitability of M1 (amplitude, LAT and rMT of MEPs) before the last session of EA (T0*). RESULTS: The amplitude of MEPs at T1 and T2 in the EA₀ group, at T0* in the EA_6h group and at T1, T2 and T3 in the EA_48h group was higher when compared with the value at T0 in each group separately (P<0.001). At T1, the amplitude of MEPs in the EA₀ group and the EA_48h group was higher than that in the EA_6h group (P<0.001, P<0.01); at T2, it was higher in the EA₀ group when compared with that in the EA_6h group (P<0.01); at T3, the amplitude in the EA₀ group and the EA_6h group was lower than that of the EA_48h group (P<0.001). The LAT at T1 was shorter than that at T0 in the three groups (P<0.05), and the changes were not obvious at the rest time points compared with that at T0 (P > 0.05). The GPT completion time of healthy subjects in the EA₀ group and the EA_48h group at T1, T2 and T3 was reduced in comparison with that at T0 (P<0.001). The completion time at T3 was shorter than that at T0 in the EA_6h group (P<0.05); at T2, it was reduced in the EA_48h group when compared with that of the EA_6h group (P<0.05). There were no significant differences in rMT among the three groups and within each group (P>0.05). CONCLUSIONS Under physiological conditions, EA has obvious after-effect on corticospinal excitability and upper limb motor function. The short-term interval protocol (6 h) blocks the after-effect of EA to a certain extent, while the long-term interval protocol (48 h) prolongs the after-effect of EA.

OBJECTIVE: To investigate the effectiveness of dorsal perforator flap of cross-finger proper digital artery in the treatment of finger soft tissue defect caused by high-pressure injection injury. METHODS: Between July 2011 and June 2020, 14 cases of finger soft tissue defect caused by high-pressure injection injury were repaired with dorsal perforator flap of cross-finger proper digital artery. All patients were male, with a mean age of 36 years (range, 22-56 years). The defects were located on the index finger in 8 cases, middle finger in 4 cases, and ring finger in 2 cases. The causes of injury include 8 cases of emulsion paint injection, 4 cases of oil paint injection, and 2 cases of cement injection. The time from injury to debridement was 2-8 hours, with a mean time of 4.5 hours. The soft tissue defects sized from 4.0 cm×1.2 cm to 6.0 cm×2.0 cm. The flaps sized from 4.5 cm×1.5 cm to 6.5 cm×2.5 cm. The donor site of the flap was repaired with skin graft. The pedicle was cut off at 3 weeks after operation, and followed by functional exercise. RESULTS: All flaps and skin grafts at donor sites survived, and the wounds healed by first intention. Twelve patients were followed-up 16-38 months (mean, 22.6 months). The texture and appearance of all flaps were satisfactory. The color and texture of the flaps were similar to those of the surrounding tissues. The two-point discrimination of the flap was 10-12 mm, with a mean of 11.5 mm. There were different degrees of cold intolerance at the end of the affected fingers. At last follow-up, the finger function was evaluated according to the Upper Extremity Functional Evaluation Standard set up by Hand Surgery Branch of Chinese Medical Association, 3 cases were excellent, 8 cases were good, and 1 case was poor. CONCLUSION The dorsal perforator flap of cross-finger proper digital artery can effectively repair finger soft tissue defect caused by high-pressure injection injury. The operation was simple, and the appearance and function of the finger recover well.

The shoulder joint is the most flexible joint in the body with the largest range of motion, and the movement pattern is more complex. Accurate capture of three-dimensional motion data of the shoulder joint is crucial for biomechanical evaluation. Optical motion capture systems offer a non-invasive and radiation-free method to capture shoulder joint motion data during complex movements, enabling further biomechanical analysis of the shoulder joint. This review provides a comprehensive overview of optical motion capture technology in the context of shoulder joint movement, including measurement principles, data processing methods to reduce artifacts from skin and soft tissues, factors influencing measurement results, and applications in shoulder joint disorders.

PURPOSE: The present study aimed to treat fractures of the distal end of the radius in children with Robert Jones (RJ) bandage. The objective was to compare this treatment modality with the cast regarding the frequency of the complication occurrence, child comfortability, and family satisfaction. METHODS: The study was a randomized controlled non-inferiority clinical trial including children with recent (less than 5 days) fractures at the distal end of the radius OTA/AO 23-A2, which is usually treated conservatively. Those with open fractures, pathological fracture, severely displaced fracture that needs reduction or multiple injuries were excluded. The participants were divided randomly into 2 groups according to the treatment modalities. Group 1 was treated by plaster of Paris cast (the control group), and Group 2 by modified RJ bandage (the trial group). The difference between the 2 groups was found by the Chi-squared test. The difference was considered statistically significant when the p value was less than 0.05. RESULTS: There were 150 children (aged 2 - 12 years, any gender) included in the study, 75 in each group. The complications occured in 5 (3.3%) cases only, pressure sores of 3 cases in Group 1 and fracture displacement of 2 cases in Group 2. There was no statistically significant difference in the rate of complication occurrence between both modalities of treatment (p = 0.649). Children treated by RJ bandages were more comfortable than those treated by the cast (97.3% vs. 73.3%, p < 0.001) with a statistically significant difference between them. Contrary to that, the families were more satisfied with the cast than RJ bandage (88.0% vs. 81.3%), but without a statistically significant difference (p = 0.257). CONCLUSION RJ bandage is a non-inferior alternative to the cast for the treatment of fractures at the distal end of the radius that can be treated conservatively in children.
