Purpose: This study aims to determine the effect of Jeonbuk tri-pull taping and proprioceptive neuromuscular facilitation (PNF) exercise on the shoulder's active range of motion, pain, subluxation, upper extremity function, and activities of daily living in patients with stroke. Methods: In this study, Jeonbuk tri-pull taping and PNF exercise were applied to three patients with stroke and subluxation. The tape was removed and new tape applied for two days every Monday, Wednesday, and Friday over six consecutive weeks. PNF exercise was applied five times a week for six weeks. To measure the range of motion, a smart phone clinometer application was used, and the degree of pain was measured using a visual analogue scale (VAS). A jig measuring method was employed to measure the distance of subluxation. The Fugl-Meyer Assessment (FMA) was used to evaluate arm function, and the modified Barthel Index (MBI) was employed to evaluate the activities of daily living. Results: The shoulder's active range of motion was improved in the patients compared to the range of pre-tests, and the pain and subluxation distance were reduced compared to those of pre-tests. Arm function and activities of daily living were increased compared to those of pre-tests. Conclusion: The study results verified that Jeonbuk tri-pull taping and PNF exercise are useful when applied to patients with subluxation and stroke.

Purpose: The purpose of this study is to analyze the effect of the arm extension pattern of proprioceptive exercise program on the muscle activity of the opposite lower extremity. Methods: In this study, electromyogram MP150(Biopac system, USA) was applied to 20 healthy male subjects. Arm extension-adduction-internal rotation pattern was applied within initial, mid and end range in sling position and supine position for measurement. And the effect on the activity of rectus femoris and tibialis anterior muscle of the opposite lower extremity was compared and analyzed. Results: The results of this study were summarized as follows: First, there was a statistically significant difference of the activity of the tibialis anterior muscle within the Initial range in sling position and supine position(P<0.05). Second, there was a statistically significant difference of the activity of the tibialis anterior muscle within the end range in sling position and supine position(P<0.05). Conclusion: Rectus femoris and tibialis anterior muscles shows the higher activity in the supine position than in the sling position. Therefore, the supine position is more appropriate than the sling position to make irradiation on lower extremity muscle with the extension pattern.

Purpose: The purpose of this study was to compare the immediate effect on the change in muscle stiffness in the common extensor muscle (CEM) when using the spiral taping method to promote proprioception. Methods: There were 18 participants in this study. CEM stiffness was measured using a MyotonePRO device with the subject in a sitting position and according to the proprioceptive neuromuscular facilitation (PNF) arm pattern. Elastic tape was used as the material for the three taping methods employed in the study: kinesiotaping (KT), right spiral taping (RST), and left spiral taping (LST). The taping methods were applied to the wrist extensor muscle with elongation position. Additionally, when performing PNF arm patterns, spiral taping in diagonal and spiral directions was used to promote CEM proprioceptors. The change in CEM stiffness was compared with the initial data values. Results: The results of this study were obtained by comparing and measuring changes in CEM stiffness using three different tapings. It was found that the stiffness change of the CEM was significant compared to the initial value, and the increase in stiffness of the CEM after RST application was also significant. Conclusion: The results of this study show that by affecting the strength and activation of the extensor muscle, taping performed through the RST method had the most positive effect on the change in CEM stiffness.

Purpose: The purpose of this study was to analyze the effect of arm flexion patterns of proprioceptive neuromuscular facilitation on muscle activation in the contralateral lower extremity. Open kinematic chain and closed kinematic chain positions were used. Methods: This study used an electromyogram (MP150, Biopac Systems, USA) to measure muscle activation in 20 healthy male students. Comparative analysis was completed on muscle activation of the vastus lateralis, biceps femoris, tibialis anterior, and gastrocnemius of the contralateral lower extremity. Open kinematic chain and closed kinematic chain positions were used with a unilateral arm flexion-abduction-external rotation pattern. Paired t-tests using the SPSS 12.0 for Windows analyzed the data produced by the electromyogram. Results: There was a statistically significant difference in muscle activation in the biceps femoris, gastrocnemius, and tibialis anterior when the open kinematic chain and closed kinematic chain positions were compared (p < 0.05). Conclusion: The biceps femoris, gastrocnemius, and tibialis anterior muscles showed greater muscle activation in the closed kinematic chain position when compared to the open kinematic chain position.

Objective : The purpose of this study was to evaluate the influence of a community based group exercise intervention on motor functional capacity. To evaluate the immediate(post-treatment) effects after 6-weeks exercise program on the group exercise intervention(PNF and Circuit exercise). Methods : Subjects-Included persons with stroke who were living in the community. Thirty-seven subjects were randomly assigned to the PNF, Circuit exercise and control group participated in a repeated measures design that evaluated the subjects with pre-treatment, post-treatment(6 weeks). Functional ability outcome measures assessed the motor assessment scale(MAS) and EMG. Both treatment groups participated in exercise cJass three times a week for 6 weeks. Group programs focused on balance, functional motor capacity and walking ability. The PNF program was modified PNF pattem and techniques with emphasis on functional tasks when possible, as well as stretching of the more affected limb particularly in the more affected shoulder. The Circuit program with subjects completing practice at a selies of work station as well as participating in walking races and relay with other members of the group. Results : Compared with the control group, the treatment group had larger improvements in the motor function ability after 6 weeks treatment and Post-treatment test scores were more significant than the pre-treatment score. 1. Motor function were assessed by using MAS, sit to stand, walking and upper function were assessed pre-treatment versus post-treatment measures revealed a statically significant(p<.05). There were significant differences between the groups. Compared with the control group, the treatment group had larger improvements. 2. In the treatment groups, demonstrated difference in the electromyographic activation of biceps, triceps, quadriceps and tibialis anterior muscles on the paretic side in the response to the reaching arm movement and stepping motion in stance. The difference in muscle activation improvement were not statically significant. Conclusion : The results of this study showed that the PNF and Circuit group exercise intervention can improve motor functional ability. This study suggests that the PNF and Circuit exercise programs is appropriate for community-based group exercise principles. It leads to gain and maintain potential function for disabled persons after stroke in the community.

Purpose: The purpose of this study was to compare the effects of passive scapular upward rotation and posterior tilt and active scapular posterior tilt on the muscle activity of the upper trapezius (UT), lower trapezius (LT), and serratus anterior (SA). Methods: Fifteen healthy subjects performed general arm elevation, arm elevation with passive scapular upward rotation and posterior tilt, and arm elevation with active scapular posterior tilt. For active scapular posterior tilt, the subjects were trained in this movement using visual biofeedback and a motion sensor. During each arm elevation condition, electromyography was used to measure the muscle activity of the UT, LT, and SA. The measured data were analyzed using a one-way repeated ANOVA. Results: LT muscle activity was significantly increased during arm elevation with active scapular posterior tilt compared to both general arm elevation and arm elevation with passive scapular upward rotation and posterior tilt (p < 0.05). SA muscle activity was greater during arm elevation with passive scapular upward rotation and posterior tilt than during general arm elevation (p < 0.05). There was no significant change in UT muscle activity among the tested arm elevation conditions (p > 0.05). Conclusion: Performing arm elevation with active scapular posterior tilt and performing arm elevation with passive scapular upward rotation and posterior tilt may be useful strategies for increasing muscle activation of the LT and SA, respectively.

Purpose: The objective of this case report is to examine the impact of physical therapy using the proprioceptive neuromuscular facilitation (PNF) concept for a patient with shoulder impingement syndrome. Methods: The patient is a 35-year-old female who has felt pain in the right shoulder for one month. The physical examination evaluated sensory integration, pain, joint integration and mobility, posture, reflex integration, range of motion, muscular strength, analysis of movement, and shoulder function. Comprehensive physical therapy was given to the patient, including stretching, mobilization, strengthening, posture correction, coordination improvement, daily activities, and sports exercises. The therapy was given 5 times a week for the first 5 weeks, then 3 times a week for the next 5 weeks. In all, the intervention lasted for 10 weeks. Results: The patient's senses, posture, and muscular strength all improved to a normal level. The degree of pain fell from 3/10 to 0/10 for activities taking place below shoulder height, and from 8/10 to 1/10 for activities above the head. Additionally, joint integration, motility, range of motion, and movements also improved. The disabilities of the arm, shoulder and hand (DASH) for functional evaluation improved from 27.5 to 10.3. Conclusion: Physical therapy using the PNF concept is effective in improving the body structure, function, activity, and participation of patients with motor disorders of the shoulder impingement syndrome.

Purpose: The purpose of this study was to investigate the effects of a modified constraint induced movement therapy (mCIMT) using proprioceptive neuromuscular facilitation (PNF) on the upper extremity function and activities of daily living (ADLs) in patients with subacute stroke. Methods: Fourteen participants with subacute stroke were randomly assigned to a group using both mCIMT and PNF or a group using mCIMT alone. Each group underwent twenty sessions (1 h/d, 5 d/wk) for 4 weeks. Patients were assessed with the action research arm test (ARAT), the Fugl-Meyer assessment for the upper extremities (FMA-UE), the Modified Barthel Index (MBI), and motor activity logs (MALs; amount of use [AOU] and quality of movement [QOM]). Results: Both the experimental group and the control group showed significant intragroup improvement in the ARAT, FMA-UE, MBI, and MAL-AOU (p<0.05). The group using both mCIMT and PNF exhibited greater improvement in the ARAT, FMA-UE, MBI, and MAL-AOU than did the group using mCIMT alone. Statistical analyses showed significant differences in the ARAT (p=0.01), FMA-UE (p=0.01), MBI (p=0.00), and MAL-AOU (p=0.01) between the groups. Conclusion: This study applied mCIMT combined with PNF for subacute stroke patients, and the results showed significant improvements in the patients' upper extremity function and ADLs. Therefore, mCIMT using PNF may be more effective than mCIMT alone in improving upper limb function and ADLs in patients with subacute stroke.

Purpose: This study aimed to examine the elderly physical fitness test for elderly people living in urban areas and to evaluate the physical fitness level according to gender and age groups. Methods: The subjects were 180 elderly people aged 65 and over living in urban areas. The elderly people were classified into early old age, middle old age, and advanced old age groups. Five items of the physical fitness test for the elderly (arm curl, chair stand, 2 min step test, back scratch, and chair sit and reach). Results: In analyzing the average of each item by gender and age, a significant difference was found in the results of each item as age increased in all sports, but no difference was observed according to gender except dumbbell lifting. Conclusion: Although the physical fitness level of all ages decreased from early age to late age, the difference in physical fitness according to gender was not significant except the arm curl test. The results of this study can be used as basic data for a new "age-specific exercise program" for the elderly.
