Purpose : To describes the important aspects of scapular movement and function used when applying PNF technique to the upper limb and scapular. Method : The scapular was a very important roles in the upper limb movement. This study summarizes the physiologic movement of scapular to the PNF upper extremity patterns or scapular patterns. Result : The shoulder joint has the most freedom of range of motion in the human body, composed of the glenohumeral joint, the subacromial joint, the acromioclavical joint, the sternoclavicular joint, the scapulothoracic joint, the costosternal joint, and the costovertebral joint. During upper limb movement, the scapular position change at the sternoclavicular joint and the acromioclavical joint. This concerted motion was characterized by scapulohumeral rhythm. In clinical situations, it is import to understand factors affect the scapulohumeral rhythm so that optimal evaluation and therapeutic intervention can be devised. Conclusions : The scapular movement depend on the proper and coordinated contraction of muscles. Physical therapists need to understand the normal scapular movement relationships of the scapulohumeral rhythm under different interventions for PNF techniques application.

Purpose : The purpose of this article was to review the literature on change of knee position sense after total knee replacement intervention in knee rehabilitation. Methods : This review outlines scientific findings regarding different literature data in knee rehabilitation, and discusses proprioceptive change of knee joints after total knee replacement intervention. Result : Severe pain and diminished joint sensation may precipitate degenerative changes of knees joint, and a strong association between decreased proprioception and function has been identified in elderly patients with knee osteoarthritis. Total knee replacement(TKR) of the knee joint are effective surgical procedures in osteoarthritis patients, resulting in decreased pain, and improved physical function and quality of life in patients. After total knee replacement, joint position sensation is partially recovered, which may improve functional stability of the knee, but aspects of physical functioning are not fully restored to preoperative status. Conclusions : Thus, recovery rate in proprioception after TKR also is considered to be important because it may be a significant risk factor in failure of total knee replacement and knee rehabilitation intervention.

Purpose : The purpose of this study was to study the effect of rectus abdominal muscle contraction by proprioceptive neuromuscular facilitation trunk stabilization training using extremity simultaneous pattern (PNF trunk stabilization training) and traditional trunk stabilization training methods. Methods : A group of 24 adults male and female, healthy, with no previous medical history nor disability in neuromuscular system and musculoskeletal system was chosen as subjects, and was divided into a control group, a PNF trunk stabilization training group and a traditional trunk stabilization training group. Experiments were performed on the last two groups, 3 times a week for 6 weeks, totaling 18 times. Using a dynamometer, muscle strength and endurance time on trunk flexion were measured before and after each experiment, and surface electromyography in left and right rectus abdominis were measured. Results : following results were obtained; 1. As for the change in the maximal voluntary isometric contraction (MVIC), all subjects in the trunk stabilization training group showed significant difference from those in the control group. 2. As for surface electromyography measurement and the changes in root mean square at the time of trunk flexion, in the left rectus abdominis, PNF trunk stabilization training group showed significant difference from the control group, while in the right rectus abdominis, traditional trunk stabilization training group showed significant difference. Conclusion : To sum up the results, both trunk stabilization training groups showed improvement in the MVIC of abdominal muscle, motor unit action potential activity, but the difference between two trunk stabilization training groups was not significant. Therefore, while trunk stabilization training significantly improved abdominal muscle contraction, but the difference attributable to training methods was found to be insignificant.

PURPOSE: The purpose of this study applied computerized cognitive therapy and proprioception exercise to stroke patients and analyzed improvement in their changes in Electrocephalogram(EEG). METHODS: The subjects were 30 patients who were diagnosed with stroke and they were randomly selected to a proprioceptive training group(n=15), a cognitive training group(n=15). The experiment was performed for three times per week for 6 weeks and EEG was measured before and after the experiment. RESULT: Before and after the experiment in each group of experiments, the ${\alpha}$-and ${\beta}$-wave study showed significant changes but, there was no significant difference in the change between groups before and after the experiment. CONCLUSION: From the above results, the cognitive training and the proprioception training have a positive impact in stroke patients EEG changes, but it is difficult to suggest a better therapeutic interventions. However, as compared with that the cognitive training that directly involved in the cognitive and brain activation, the proprioception training have changes on brain activation. Therefore, of Clinical therapeutic interventions, the proprioception training can be presented effectively to the changes in brain activation in stroke patients.

The study examined the effects of trunk pattern exercise in proprioceptive neuromuscular facilitation (PNF) integrated transcranial direct current stimulation (tDCS) on the muscle activity and balance, walking speed in stroke patient. Thirty-one patients with hemiplegia due to stroke were assigned to either the experimental group (n=15) or control group (n=16). Both groups performed trunk pattern training in PNF for 3 times per week over a 6 week period for 20 minutes per session. The experimental group performed additional tDCS for 20 minutes. A comparison of the two groups after the intervention showed that the exercise program in experimental group had a more significant on the gastrocnemius, tibialis anterior and balance than the control group (p<.05). This showed that trunk pattern exercise in PNF integrated tDCS had a positive effect on the functional recovery of the lower extremity in stroke patients.

The purpose of this study was to compare the effects of one proprioceptive neuromuscular facilitation technique and static stretching on calf muscle tightness. The subjects consist of 9 hemiplegics, and 9 quadriplegics. The eighteen subjects were randomly divided into 3 groups: prorioceptive neuromuscular facilitation(6 persons), static stretching(6 persons) and control(6 persons). Contract relax antagonist contract and static stretching techniques were applied continuously for twenty minutes each. Of the many proprioceptive neuromuscular facilitation techniques, only the contract relax antagonist contract technique was applied. The static stretching technique was applied with the subject placed in standing on a seventy degree inclined tilt table for twenty minutes. A wedge was placed under the feet to obtain maximum dorsiflexion. Wedge thickness varied with each subject. Results revealed: (1) a significant difference between the experimental and the control groups(p<0.05). (2) a significant difference between contract relax antagonist contract and static stretching groups(p<0.05). (3) At day five, the final increments were: contract relax antagonist contract $11.9{\pm}1.90^{\circ}$, static stretching $7.7{\pm}2.3^{\circ}$(mean${\pm}$standard deviation).

Purpose: This study attempts to identify the effects of stretching and core exercise using proprioceptive neuromuscular facilitation (PNF) on the pain and functional disability index of patients with chronic lower back pain. Methods: A total of 20 patients with chronic lower back pain were randomly divided into either the experimental group (n=10), who received PNF stretching and core exercise, or the control group (n=10), who received conventional physiotherapy. Both interventions were applied three times a week for six weeks. The visible analogue scale (VAS) was measured in order to determine the level of pain, while the Oswestry Disability Index (ODI) was used to measure the change in the functional disability index. We conducted a paired t-test to compare the within-group change before and after the intervention. To compare the between-group difference, we used an independent t-test. The statistical significance level was set at ${\alpha}=0.05$ for all the variables. Results: The experimental group showed a significant within-group change in both the VAS and the ODI (p<0.01). The control group also showed a significant change (p<0.01). A significant difference was observed between the experimental group and the control group with regard to the change in both the VAS and the ODI after the interventions (p<0.01). Conclusion: In this study, the application of stretching and core exercise using PNF for subjects who complain of chronic lower back pain proved effective in reducing both pain and functional disability. We therefore expect that this intervention can be applied in the future as a useful program for patients with chronic lower back pain.
