This study was to investigate whether a trunk correction taping plus scapular setting exercises has an effect on trunk muscle activation and trunk balance and upper extremity function in patients with stroke. Twenty stroke patients were randomly divided into a trunk correction taping with scapular setting exercise group (n=10) and a scapular setting exercise group (n=10), and each group performed given interventions for 30 minutes for 4 weeks. In the experimental group, there were significant increases in muscle activation, K-TIS, and MFT (p<.05), and a significant improvement was detected in K-TIS and MFT compared to the control group (p<.05). This study suggests that a trunk correction taping with scapular setting exercises was more effective on trunk muscle activation, trunk balance, and upper extremity function in stroke patients compared to a scapular setting exercise. It could be clinically more significant if the change in the onset time of muscle activity is confirmed in the further researches.

Objectives The purpose of this study is to systematically explore the effects and safety of acupuncture treatment for upper extremity peripheral nerve injury and to review the methodology of clinical trials. Methods We searched 9 electronic databases(3 international, 1 Chinese, 5 Korean) including English, Korean and Chinese, up to December 2017 for randomized controlled trials which evaluated the effects of the acupuncture in patients with upper extremity peripheral nerve injury. We abstracted the designs of the randomized clinical trials and the method of acupuncture treatment according to the Standards for Reporting Interventions in Clinical Trials of Acupuncture(STRICTA). Results A total of 8 papers were reviewed. All randomized clinical trials were conducted in China. Of them, five studies(62.5%) were electro-acupuncture as intervention. All randomized clinical trials reported favorable effects of acupuncture treatments compared to baseline or control group with outcomes of efficacy rate. However risk of bias seemed high. LI4, LI11, SI3, PC3, PC6 were most frequently used for acupoints to treat upper extremity peripheral nerve injury. Conclusions These results suggest that it is recommended to develop more detailed reporting standards for acupuncture treatment method. In the future, well designed randomized clinical trials which evaluate the effects and safety of acupuncture treatment for upper extremity peripheral nerve injury is highly needed.

Despite most of tasks in manufacturing, construction and agriculture, etc., were currently mechanized and automated, manual materials handling still existed in atypical working condition. In case of manual materials handling, repetitive work, inappropriate working posture, excessive force, contact stress might cause overload, which could lead to work-related musculoskeletal disorders and low back pains. On this basis, the goal of this study is to reveal the effects of various lifting postures of trunk angles and lower extremity postures on maximum holding time(MHT). Twenty two subjects were recruited from a university population. The experiment was designed by a combination of three trunk angle ($0^{\circ}$, $20^{\circ}$, $60^{\circ}$) and three lower extremity postures(straight, bent, kneeling). Before experimental trials, subjects performed MVC(maximum voluntary contraction) exertions in three trunk angles ($0^{\circ}$, $20^{\circ}$, $60^{\circ}$) to calculate 30%MVC at designated postures. In each trial, they were required to hold the handheld load(30%MVC) for a designated posture as long as they could. The results of MVC by trunk angles were measured in $0^{\circ}$ > $20^{\circ}$ > $60^{\circ}$ orders, but those of MHT measured in $20^{\circ}$ > $0^{\circ}$ > $60^{\circ}$ orders. These results showed that straight posture is the ideal working posture in work exerted a strong force for a short time, but the ability to work might be improved in the trunk angle $20^{\circ}$ in work required 30%MVC for a long time. Also, results of MVC and MHT by lower extremity postures measured in straight > bent > kneeling orders.

Background Free muscle flaps are a mainstay for reconstruction of distal third leg wounds and for large lower extremity wounds with exposed bone. However a major problem is the significant postoperative flap swelling, which may take months to resolve. We studied the efficacy and safety of immediate application of a vacuum assisted closure (VAC) dressing after a free muscle flap to the lower extremity. Methods Over a 19 months period, all consecutive free muscle flaps for lower extremity reconstruction at a Level I trauma center were evaluated prospectively for postoperative flap thickness, complications and flap survival. Immediate application of a VAC dressing was performed in 9 patients, while the flap was left exposed for monitoring in 8 patients. Results There was no statistically significant difference in flap survival between both cohorts. Mean flap thickness at postoperative day 5 for the VAC group was $6.4{\pm}6.4mm$, while flap thickness for the exposed flap group was $29.6{\pm}13.5mm$. Flap thickness was significantly decreased at postoperative day 5 for the VAC dressing group. Conclusions Immediate application of VAC dressing following free muscle flaps to the lower extremity does not compromise flap survival or outcomes and results in decreased flap thickness and a better aesthetic outcome.

Background Identifying patients who may be at high risk for wound complications postsarcoma resection and reconstruction is essential for improving functional outcomes and quality of life. Currently, the effect of timing on sarcoma reconstruction has been poorly investigated. The purpose of this study was to compare outcomes of delayed and immediate reconstruction in the setting of sarcoma resection requiring flap reconstruction in the lower extremity. Methods A retrospective review of the senior author's sarcoma reconstruction patients from January 2005 to July 2017 was completed. All patients undergoing flap reconstruction of the lower extremity were included. Complications in the early postoperative period were compared between delayed and immediate reconstructive procedures. Results A total of 32 patients (7 delayed, 25 immediate) were included in this study. There was a significantly increased rate of overall complications (100% vs. 28.0%, P=0.001) and rate of hematomas (28.6% vs. 0.0%, P=0.042) in the delayed reconstruction group. Other complications including dehiscence, seroma, infection, venous thrombosis, and total/partial flap loss were also increased in the delayed reconstruction group, but this was not considered to be significant. Conclusions This study suggests that delayed reconstruction following sarcoma resection of the lower extremity had a higher incidence of overall complications and hematoma formation. We emphasize the importance of early plastic and reconstructive surgeon referral and the necessity to closely monitor delayed reconstruction patients for complications.

Purpose: Driving is essential to maintain independent living status in modern times. Many patients want to know when they can drive again, but it's only possible if they have the ability to control lower extremity muscles. In this study, we compared the effects of velocity on onset time of lower extremity muscles during driving tasks. Methods: Twelve participants (5 male, 7 female) were enrolled. EMGs were used to test the onset time of lower extremity muscles; tibialis anterior, soleus, rectus femoris. To analyze the data, we used two way ANOVA. Results: According to brake pedaling velocity, there was a significant difference in brake response time (p<0.05). Further, when comparing the lower extremity muscles, there was a significant difference in onset time (p<0.05). The order of muscle recruitment was tibialis anterior, rectus femoris, and soleus for achieving maximal velocity, but the order was rectus femoris, tibialis anterior, soleus for achieving submaximal velocity. Conclusion: Brake pedaling velocity has significant effects on onset time of muscle contractions in the lower extremities. We suggested that a future study needs more subjects and more detailed research such as evaluat-ions of visuo-motor coordination and fine motor dexterity.

Purpose: To explore the effects of action observation combined with modified constraint-induced movement therapy on upper-extremity function and the activities of daily living in subacute stroke patients. Methods: Twenty-four subacute stroke patients were randomly assigned to the experimental group or the control group (n = 12 each). Both groups received therapy based on motor learning concepts, including repetitive and task-specific practice. The experimental group watched video clips for 10 minutes related to tasks performed during modified constraint-induced movement therapy while the control group watched videos unrelated to upper-extremity movement. These programs were performed for 40 minutes a day five times a week for four weeks. Their scores on the Fugl-Meyer assessment of upper extremities (FMA-UE), the action research arm test (ARAT), a motor activity log (amount of use [AOU] and quality of movement [QOM]), and the modified Barthel index (MBI) were recorded. Results: In both groups, all variables were significantly different between the pre-test and post-test periods (p < 0.05). The post-test variables were significantly different within each group (p < 0.05). In the experimental group, the changes between pre-test and post-test scores in the FMA-UE (14.39 ± 4.31 versus 6.31 ± 4.63), the ARAT (16.00 ± 4.73 versus 11.46 ± 3.73), MAL-AOU (1.57 ± 0.15 versus 1.18 ± 0.28), and MBI (27.54 ± 4.65 versus 18.08 ± 8.52) were significantly higher than those of the control group (p < 0.05). Conclusion: These findings suggest that action observation combined with modified constraint-induced movement therapy may be a beneficial rehabilitation option to improve upper-extremity function in subacute stroke patients with moderate impairment.
