Background: Patellofemoral pain is one of the common diseases of the musculoskeletal system. Many previous studies have recommended the application of exercise therapy to patellofemoral pain patients for treatment. The purpose of this study was to investigate effect of coordinative locomotor training (CLT) and sling exercise combined program on knee pain and functional movement in patellofemoral pain patient. Methods: In this study, single-subject design (A-B-A') was conducted for 6 weeks. A repeted-measure analysis was conducted to assess results of the anterior knee pain scale (AKPS), Clarke's test (CT), eccentric step down test (ESDT). During the intervention (B), the CLT and sling exercise combined program was conducted three times a week for 4 weeks. Results: From baseline period A to intervention period B, the AKPS, CT, ESDT were improved from 61 to 48 (27%), from 8.33 to 3 (64%), from 7.67 to 3,58 (53%). From baseline period A to baseline period A', the AKPS, CT, ESDT were improved from 70.67 to 48 (47%), from 0.67 to 3 (92%), from 1.33 to 3,58 (83%). Conclusion: Based on the results of this study, we recommend the application of CLT and sling exercise combined program to improve the pain and functional movement in patellofemoral pain patients.

Objective: The aim of this study was to analyze kinetic variables between thermotherapy and dynamic warm-up during drop-landing. Method: Twenty male healthy subjects (Age: 21.85 ± 1.90 years, Height: 1.81 ± 0.06 cm, Weight: 68.5 ± 7.06 kg) underwent three treatments applied on the thermotherapy of femoral muscles and a dynamic warm-up. The thermotherapy was performed for 15 minutes while sitting in a chair using an electric heating pad equipped with a temperature control device. Dynamic warm-up performed 14 exercise, a non-treatment was sitting in a chair for 15 minutes. Core temperature measurements of all subjects were performed before landing at a height of 50 cm. During drop-landing, core temperature, joint angle, moment, work of the sagittal plane was collected and analyzed. All analyses were performed with SPSS 21.0 and for repeated measured ANOVA and Post-hoc was Bonferroni. Results: Results indicated that Thermotherapy was increased temperature than other treatments (p = .000). During drop-landing, hip joint of dynamic warm-up was slower for angular velocity (p < .005), and left ankle joint was fastest than other treatments (p = .004). Maximum joint moment of dynamic warm-up was smaller for three joints (hip extension: p = .000; knee flexion/extension: p = .001/.000; ankle plantarflexion: p = .000). Negative work of dynamic warm-up was smaller than other treatments (p = .000). Conclusion: In conclusion, the thermotherapy in the local area doesn't affect the eccentric contraction of the thigh. The dynamic warm-up treatment minimized the joint moment and negative work of the lower joint during an eccentric contraction, it was confirmed that more active movement was performed than other treatment methods.

Purpose : Scapular dyskinesis, it have been shown to be common in overhead athletes and has been associated with RC muscle strength. Posterior shoulder tightness (PST) has been suggested as an important factor causing scapular dyskinesis. Therefore, rehabilitation programs should focus on a posterior shoulder stretch combined with scapular stabilization exercise (PSSE) intervention. Determine the effects of posterior shoulder stretch combined with scapular stabilization exercise on the rotator cuff (RC) muscles strength, functional strength ratio (FSR), range of motion (ROM), and pain. Methods : 30 adolescent baseball players participated and subjects were allocated PSSE group (n=15) or the SSE group (n=15). Both group performed a 6-weeks intervention and measured of isokinetic peak torque/body weight (PT/BW) of concentric external rotator (CER), eccentric external rotator (EER), concentric internal rotator (CIR), eccentric internal rotator (EIR), FSR, ROM, and pain. Results : After 6 weeks PSSE, significant increase CER PT/BW (+6.02±4.76 %), EER PT/BW (+5.39±4.22 %), EER to CIR ratio (+.17±.16), and internal rotation ROM (+15.08±3.57 °). Whereas, significant decrease EIR to CER ratio (-.14±.18), external rotation ROM (-12.00±6.94 °), and GIRD (-17.41±2.84 °) compared with pre-intervention. No significant difference of isokinetic PT/BW of CIR and EER post-intervention. In the SSE group showed no significant difference all measurements for isokinetic PT/BW, FSR, and ROM post-intervention. The pain was significant improve both PSSE group (-3.25±1.60) and SSE group (-2.83±1.85) post-intervention. Conclusion : Both the PSSE and SSE interventions led to more pain relief. However, only the PSSE group showed ROM, CER, EER PT/BW, and FSR improvements. These results might suggest that the PSSE intervention is a more effective program for improving RC muscle strength and balance, in particular, concentric and eccentric ER muscle strength, FSR and can expect to prevent shoulder injuries in adolescent baseball players with scapular dyskinesis.

The purpose of this study was to determine the consequence of resistance strengthening exercise on the hip flexor and extensor performed to improve functional mobility in stroke patients more than six months post stroke. Seventeen patients were randomized into two groups. Both groups received conventional physical therapy for six weeks. In addition, the experimental group performed eccentric resistance strengthening exercise in the hip flexor and extensor using an isokinetic dynamometer. The hip flexor and extensor strength, stair up and down mobility, timed get up and go (TUG), 10 m gait velocity, and functional reach were repeatedly measured at baseline, three weeks, and six weeks after treatment. The results were as follows: 1. The experimental group improved more remarkably in the hip flexor and extensor strength, stair up and down mobility, and the 10 m gait velocity after three weeks and six weeks of treatment (p<.05), 2. The control group improved significantly in the hip flexor and extensor strength, and 10 m gait velocity after three weeks of treatment (p<.05), 3. At each three and six week point, the experimental group made greater gains in hip flexor and extensor strength, stair up and down mobility, and 10 m gait velocity than the control group (p<.05). In conclusion, it is desirable to perform resistance strengthening exercises combined with conventional physical therapy to improve functional mobility in chronic stroke patients.

Delayed onset muscle soreness is a sensation of discomfort that occurs 24h after exercise, and it is associated with the performance of unfamiliar and high force muscle wor, such as eccentric contractions. The injury to the muscle has been well described but the mechanism underlying the injury is not fully understood. Although the pathophysiological processes underlying delayed onset muscle soreness are not completely understood, many researchers have investigated various treatments in a attempt to reduce the soreness. These treatments have focused on reducing the inflammation, or edema, consequent to tissue damage, and breaking up the cycle which is thought provoke tonic muscle spasm or pain. Physical therapy is the most importance thechniques to reduce delayed onset muscle soreness. Physical therapy on delayed onset muscle soreness includes massage, exercise, therapeutic ultrasound, TENS, stretching and cryotherapy, this investigation should encourage physical therapists to experiment further with various techniques to reduce delayed onset muscle soreness.

The purpose of this study was to investigate useful manual therapy techniques for peripheral facial nerve palsy and to propose guidelines to be applied for current manual therapy techniques. Several databases were searched to find manual therapies for facial palsy. These therapies included cervical, and temporomandibular joint chuna manual therapy, proprioceptive neuromuscular facilitation, neuromuscular re-education, facial exercise, and mime therapy. Both cervical, and temporomandibular joint chuna manual therapy release nerve compression, helping blood circulation and nerve conduction. Proprioceptive neuromuscular facilitation uses irradiation, bilateral activation, and eccentric facilitation to improve muscle power and symmetry. Neuromuscular re-education, as a retraining tool for facial movement patterns, enhances neuromuscular feedback. Facial exercise helps the patient continuously move and massage facial muscle themselves. Mime therapy aims to develop a conscious connection between the use of certain muscles and facial expressions. The use of facial chuna manual therapy for peripheral facial nerve palsy can stimulate the proprioceptive neuromuscular receptors in the face. Peripheral facial nerve palsy has 4 phases; progress phase, plateau phase, recovery phase, and sequelae phase. Each phase needs different treatments which include relaxation, assistance, resistance, origin-insertion extension, and nerve pathway expansion.
