Background: Randomized controlled trials (RCTs) provide evidence on the effectiveness and safety of interventions and inform systematic reviews and guideline preparation for clinical application. However, methodological flaws can occur in many RCTs, and Cochrane's risk of bias version 2 (RoB2) can be used to evaluate RCTs' risk of bias (RoB). However, physical therapy RCTs in Korea did not confirm RoB. Therefore, the purpose of this study was to evaluate RoB using RoB2 in RCTs published in the Korean Physical Therapy Journal. Design: Review. Methods: The RCTs subject to evaluation were RCTs published in 11 physical therapy journals in Korea from 2018 to 2022. RoB2 evaluated a total of five domains: bias arising from the randomization process, bias due to deviations from intended interventions, bias due to missing outcome data, bias in measurement of the outcome, and bias in selection of the reported result. Results: A total of 616 RCTs were evaluated. As for bias arising from the randomization process, high risk was the highest at 555 (90.1%), followed by low risk at 41 (6.7%) and some concerns at 20 (3.2%). For bias due to deviations from intended interventions, the proportion of some concerns was the highest at 390 (63.3%), followed by high risk at 218 (35.4%) and low risk at 8 (1.3%). As for the bias due to missing outcome data, the rate of low risk was the highest at 399 (64.8%), followed by high risk at 159 (25.8%) and some concerns at 58 (9.4%). As for bias in measurement of the outcome, high risk was the highest at 294 (47.7%), followed by low risk at 224 (36.4%) and some concerns at 98 (15.9%). In the bias due to missing outcome data, the ratio of high risk was the highest at 610 (99%), followed by low risk at 4 (0.7%) and some concerns at 2 (0.3%). Conclusion: Most of the RoB evaluation results of RCTs published in the Korean Physical Therapy Journal were rated as high risk. Methodological quality of RCTs needs to be improved.

Background: The number of old people with degenerative osteoarthritis one of the chronic disease, were constantly increased. Many researchers have made a great effort to verify the effects of ultrasound and laser therapy in degenerative osteoarthritis treatment. This study applied ultrasound-laser integration therapy on knee joint degenerative osteoarthritis and compared its effect with ultrasound and laser. Methods: We assigned 60 patients age 65 to 85 who had been diagnosed as knee joint degenerative osteoarthritis in G nursing home in Daejeon city. Randomization was done in blocks of three, holding twenty people per each group to receive either ultrasound, laser, ultrasound-laser integration therapy. This study carried out the experiment for 6 weeks to from April 17, 2010. We measured variables using visual analog scale (VAS) and pressure threshold meter (PTM) of the effects by before and after exercise. Results: It has been found that VAS was reduced and PTM was increased in all three groups. Compare with the other groups, Ultrasound-laser integration therapy group had lower VAS and higher PTM than ultrasound therapy and laser therapy group. Conclusions: These results lead us to the conclusion that ultrasound-laser integration have influenced the pain reduction of the knee degenerative osteoarthritis.

A linear quantitative structure-property relationship (QSPR) model is presented for the prediction of rejection in permeation through membrane. The model was produced by using the multiple linear regression (MLR) technique on the database consisting of retention data of 25 pesticides in 4 different membrane separation experiments. Among the 3224 different physicochemical, topological and structural descriptors that were considered as inputs to the model only 50 were selected using several criteria of elimination. The physical meaning of chosen descriptor is discussed in detail. The accuracy of the proposed MLR models is illustrated using the following evaluation techniques: leave-one-out cross validation procedure, leave-many-out cross validation procedure and Y-randomization.

Purpose: The purpose of this study was to examine the effect of three-week contract-and-relax (CR) interventions with and without reinforcement using temporal summation for flexibility and dynamic balance ability in young people with hamstring shortening. Methods: This study was conducted on 20 female college students with hamstring shortening. The participants were divided equally into two groups using stratified randomization: the CR group (CRG) and the CR with reinforcement group (CRRG). All interventions were applied three times a week for three weeks. The passive straight leg raise (PSLR) test and functional reaching test (FRT) were conducted on each participant before and after the three-week intervention. Results: In both groups, PSLR and FRT improved significantly after the three-week intervention compared to before intervention (p < 0.01). The amount of change in PSLR after the three-week intervention was significantly higher in CRRG than in CRG (p < 0.05). Conclusion: Three-week CR interventions with and without reinforcement were effective in improving PSLR and FRT. To improve hamstring shortening, CR intervention with reinforcement may be more useful than CR intervention without reinforcement.

Background: Ganglion impar blockade is a reliable and effective treatment option used in patients with coccydynia. Our primary objective was to specify the role of corticosteroids in impar blockade. We compared applications of local anesthetic with the local anesthetic + corticosteroid combination in terms of treatment efficiency in patients with chronic coccydynia. Methods: Our study was a prospective randomize double-blind study. The patients were divided into 2 groups after randomization. The first group (group SL) was made up of patients where a corticosteroid + local anesthetic were used during ganglion impar blockade. In the second group (group L) we used only local anesthetic. We evaluated numeric rating scale (NRS) and Beck depression scale, which were employed before the procedure and in 1st and 3rd months after the procedure. Results: Seventy-three patients were included in the final analysis. We detected a significantly greater decrease in NRS values in the 1st month in group SL than in group L (P = 0.001). In the same way, NRS values in the 3rd month were significantly lower in the group with steroids (P = 0.0001). During the evaluation of the Beck test, we detected significantly greater decreases in the 1st month (P = 0.017) and 3rd month (P = 0.021) in the SL group than in the L group. Conclusions: Ganglion impar blockade decreases pain in the treatment of chronic coccydynia and improve depression. Addition of steroids in a ganglion impar blockade is required for treatment response that should accumulate over a long period of time.

Purpose : This study was to verify the effectiveness of eccentric training and to make clinical recommendations on detailed application methods by comparing the effects of changes in acromiohumeral distance (AHD), pain intensity, muscle strength, and functional performance after applying a 12-week eccentric training program (ET group) or concentric training program (CT group) for patients with partial rotator cuff (supraspinatus) tears with moderate to severe shoulder pain. Methods : A total of 29 subjects were assigned to either the "ET group (n=15)" or the "CT group (n=14)" through simple randomization and were measured in the same way at baseline before intervention, 4 weeks and 12 weeks after intervention. All subjects received a physical therapy program 12 sessions 3 times a week for the first 4 weeks, and physical therapy program, 12 sessions a week, from 4 weeks to 12 weeks, for a total 20 sessions. Ultrasound machine was used for AHD, visual analog scale (VAS) was used for pain intensity, electronic hand held dynamometer was used for muscle strength, Korean Constant shoulder score (K-CSS) used for functional performance. Results : AHD, pain intensity, and muscle strength did not show significant differences at 4 weeks, but improved numerically, and showed significant differences at 12 weeks (p<.05), showing superior results in the eccentric training group compared to the concentric training group. Functional performance showed significant changes at both 4 and 12 weeks (p<.05), and excellent results were also found in the eccentric training group. Conclusion : In patients with partial rotator cuff tears with moderate to severe shoulder pain, an eccentric training program increased acromiohumeral distance (AHD), reduced pain, and increased muscle strength. Therefore, it can be clinically presented as an intervention method that can quickly and effectively improve functional performance, which is the ultimate goal of physical therapy.
