Background: Patellofemoral pain syndrome (PFPS) is common knee disorder encountered in clinical: notably, altered hip biomechanic may contribute to PFPS. In this study, We investigated the effects of hip joint mobilization on pain, balance, and gait in patients with PFPS. Methods: Patients were randomly assigned to a control group (n=18) or an experimental group (n=20). Both groups received exercise therapy thrice a week for 4 weeks. The experimental group performed additional hip joint mobilization thrice a week for 4 weeks. Measurement were obtained in each patient pre-intervention and post-intervention (after 4 weeks). Results: The assessed items included the visual analog scale (VAS), one leg standing test (OLS), timed up and go test (TUG), and the 10m walk test (10MWT). Post-intervention assessment showed significantly improved results in both groups (p<.01). A significant intergroup difference was observed only in the results of the 10MWT (p<.05). Conclusion: Our results indicate that hip joint mobilization with exercise therapy may be useful to improve PFPS.

Objective: The purpose of this study was to investigate the effects of a 12-week combined exercise program on gait parameters in elderly women with osteoarthritis. Method: The subjects of this study were 11 elderly women (age: $67.09{\pm}2.47$, height: $157.35{\pm}4.30cm$, weight: $62.49{\pm}6.36kg$) with knee osteoarthritis. The combined exercise program of this study was divided into aerobic exercise and lower extremity strengthening exercises. The exercises were performed for 60 minutes per session, three times a week, for a total of 12 weeks. The maximum joint moments of the hip, knee, and ankle joints with walking were obtained with 8-3D cameras (MX-T20, Vicon, USA) and 2-force plate (AMTI OR6-7-400, AMTI, USA). SPSS Windows version 23.0 was used for statistical analysis. A paired t-test was used for pre-post comparison. An alpha level of .05 was utilized in all tests. Results: The maximum extension moment was significantly higher in the hip joint after P1 on the X axis. The maximum joint moment of P3 in extension was statistically significantly lower after intervention. On the Z axis, the maximum joint moment was significantly lower after the exercise intervention at P3. There was a statistically significant increase in the extension moment of the left and right knee joints in the X axis after exercise intervention. In the right ankle joint, P1 (plantar flexion moment) showed a statistically significant high moment after exercise intervention. Conclusion: These results suggest that combined exercise, including lower limb and aerobic exercise, may have a positive effect on mobility and walking moments in patients with osteoarthritis of the knee.

Purpose: This study examined the effects of early stabilization exercise focused on the scapulothoracic joint on the recovery of surgical patients due to rotator cuff tear. Methods: The subjects were 30 patients divided randomly into two groups. Group I consisted of 15 patients who practiced shoulder joint stabilization exercises, including glenohumeral joint movement. Group II consisted of 15 patients who practiced scapulothoracic joint stabilization exercises, excluding glenohumeral joint movement. The duration of stabilization exercise was 30 minutes for one day, five days a week, and five weeks. To measure the dependent variables, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, range of motion (ROM), dynamometer of measured grip were used. Results: The DASH, ROM, and grip power were compared. A significant difference was observed before the intervention in each group (p<.05), and there was no significant difference between group I and group II (p>.05). Conclusion: Both shoulder joint and scapulothoracic joint stabilization exercises were effective after the intervention compared to preintervention, but there was no difference between the two groups. Unlike many recent studies on the initiation of stabilization exercises, this study allays the concerns between the advantages of 'early exercise' and oppositions of previous studies about 'early exercise'. Nevertheless, further research regarding these subjects is needed.

Objective: Joint mobilization for arthrokinematics altered by the positional fault of chronic ankle instability (CAI) is an effective intervention for stabilization. In this study, we compared the effects of ankle dorsi flexion range of motion (DFROM) and dynamic balance ability (DBA) in CAI patients via passive joint mobilization (PJM), a method traditionally performed in previous studies, and active joint mobilization (AJM), a method that can have a greater effect on cortical excitability with spontaneous movements. Design: Single-blind two-arm randomized controlled trial Methods: A total of 30 participants were registered: 15 each to the PJM and AJM groups. Each participant received a total of 10 intervention sessions, 10 minutes per session, 5 times a week for 2 weeks. PJM used Maitland's mobilization method to apply joint mobilization with talus in the posterior direction and AJM used an angular joint motion to induce patient's voluntary motion of medial malleolus anterior gliding and lateral malleolus posterior gliding, respectively. DFROM of the ankle was measured by using tape and DBA was evaluated by using the balance system. Results: Significant improvement was observed after intervention in both the PJM and AJM groups except for the DBA-anterior and DBA-right variables of the PJM group. There were statistically significant differences between the AJM and PJM groups in the DFROM, DBA-anterior, DBA-posterior, and DBA-right variables. Conclusions: The overall improvement of DFROM and DBA was found to be more effective in joint mobilization including voluntary movement. When it is accompanied by voluntary movement, it further affects the neuromuscular system of the ankle.

Background: This study aimed to investigate the effects of joint mobilization with movement (MWM) on pain, ankle joint range of motion, balance, and gait in patients who underwent total knee arthroplasty (TKA) and exhibited ankle joint inversion. Methods: We divided 35 patients who had undergone TKA into experimental and control groups. The intervention involved a 40-min session three times a week over 4 weeks. The control group received general physical therapy, ankle pumping exercises, Q-setting exercises, knee joint range of motion exercises, and gravity-controlled gait training. In addition to these treatments, the experimental group received MWM to evaluate knee pain, ankle joint angle, balance, and gait pre- and post-intervention. Results: Both groups experienced a decrease in pain levels, with no significant difference between the groups. Both groups also showed a significant decrease in ankle joint inversion angle, with notable differences between them. Additionally, both groups significantly increased their mean dorsiflexion angles and balance, with a significant difference observed between the groups. Although walking decreased in both groups, there was no significant difference observed between them. Conclusion: The group that received MWM treatment showed significant effects on inversion angle, dorsiflexion angle, balance, and gait. These results provide valuable insights into the potential benefits of MWM as a post-TKA intervention, while highlighting the importance of long-term follow-up studies on post-TKA lower limb alignment interventions.

Background: Examining the fidelity of intervention using music for pain alleviation is crucial in developing effective music intervention for pain management. Purposes: This study aims to examine the fidelity of music intervention studies purported to alleviate post-surgery pain. Methods: Thirteen studies from 2000 to 2023 were searched and reviewed for their intervention providers, music protocol, session management, duration, music selection, and implementation rationale. Results: Four studies (30.77%) provided interventions based on therapeutic principles for music on pain management; reporting 4 intervention components out of 7. Intervention design and evidence varied, indicating low fidelity. Conclusion: Enhancing fidelity in music interventions for post-joint replacement pain alleviation is vital for further use of music for pain management. Researchers should develop systematic interventions based therapeutic mechanism of music.

This study was conducted to examine the effect of joint mobilization on forward head posture and to propose an effective method to improve correct body posture and balance. A total of eight patients from a Maitland-applied group (n=8) received mobilization therapy to increase the mobility of the cervical joint, with Maitland's movement grade III intensity for 30 seconds of treatment and 30 seconds of rest, for ten intervals, three times a week for four weeks. The craniovertebral angle (CVA) changes before and after the intervention with the Maitland technique were measured as $56.85{\pm}2.31^{\circ}$ before, $63.23{\pm}2.23^{\circ}$ two weeks after, and $64.98{\pm}1.27^{\circ}$ four weeks after joint intervention. There were significant CVA changes before and after the Maitland technique (P <.05). The results of this study suggest that the Maitland technique is useful for improving the head vertebral angle in patients with forward head posture.

PURPOSE: Stroke patients have reduced balance ability due to a lack of motion in the ankle joint. Elastic taping assists movement, and joint mobilization, a form of passive movement, enhances mobility. The purpose of this study was to determine the immediate effects on balance ability after anterior-to-posterior (A-P) talocrural joint mobilization combined with elastic taping in stroke patients. METHODS: Twenty stroke patients were divided into two groups: a joint mobilization with taping group (experimental group, n=10) and an elastic taping only group (control group, n=10). The experimental group underwent anteroposterior mobilization of the talus and elastic tape was applied to the calf and tibialis anterior muscles. The control group had elastic tape applied. Dynamic balanced abilities were assessed by using the BioRescue system. After 30 minutes of intervention, the forward, backward, left side, and right side sway areas ($mm^2$) were measured. RESULTS: Only the experimental group showed a significant increase in forward sway area after intervention. However, no significant differences were detected between the two groups. CONCLUSION: This study shows that A-P talocrural joint mobilization combined with elastic taping has a positive effect, producing an immediate increase in the forward balance ability of stroke patients. However, this study did not examine joint mobilization alone. In subsequent studies, it is necessary to examine the effect of joint mobilization only on balance in stroke patients.

Objective: The purpose of this study was to investigate effects of taping technique applied to knee instability. Design: Cross sectional study. Methods: Twenty-six participants with knee instabilityparticipated in this study. They were randomly assigned to the Kinesio taping (KT) group (n=13) and the dynamic taping (DT) group (n=13). Both groups applied knee stabilization taping techniques. In order to compare the effects of each taping technique, the change in the landing error scoring system (LESS) and lower extremity joint angle wasrecorded before and after the intervention. Results: Both groups significantly decreased in the change before and after the LESS (p<0.05). At the joint angle of the lower extremities, KT group significantly reduced the valgus angle at the max knee flexion (p<0.05). In DT group knee joint flexion and hip joint flexion angles were significantly increased at foot contact (p<0.05). In max knee flexion, the knee joint flexion angle was significantly increased (p<0.05). In foot contact, max knee flexion, the knee joint valgus angle was significantly increased (p<0.05). DT group showed more significant changes in knee joint flexion angle at foot contact and hip joint flexion angle at max knee flexion. Conclusions: Dynamic taping is a clinically applicable intervention method for lowering the risk of non-contact injury in participants with knee instability and for knee stability during rehabilitation exercises.

PURPOSE: This study compared the changes in the range of motion (ROM ) on the knee joint according to three different isometric contraction intensities when applying Evjenth - Hamberg stretching (EHS) to the hamstring muscles of healthy subjects. METHODS: Forty eight healthy subjects aged between 20 and 39 years were allocated randomly to four groups; performing EHS at 10% maximum voluntary isometric contraction (MVIC) group, EHS at 50% MVIC group, EHS at 100% MVIC group, and control group (CG) pre-, and post-intervention. The flexibility of the hamstring muscles was evaluated using a digital goniometer for measuring the knee joint ROM motion. A Chattanooga stabilizer was used to adjust the MVIC intensity by 10%, 50%, and 100%, respectively. RESULTS: These results show that the pre- and post-intervention knee joint ROM were significantly different in all four groups (p<.05). The post-intervention knee joint ROM showed a significant difference between the 100% MVIC group and non-MVIC group (p<.05). The knee joint ROM difference between the pre- and post-interventions was similar in the 10% MVIC and 50% MVIC groups but significant differences were observed among the other groups (p<.05). CONCLUSION: EHS of the hamstring muscles was effective in improving the knee joint ROM with an isometric contraction intensity of 10%, 50%, or 100% MVIC, and of these, 100% MVIC was most effective.
