Background: Functional ankle instability (FAI) indicating a decrease in muscle strength, proprioception, neuromuscular control, balance and postural control function. Objective: To investigate the effect of jumping exercise on the supporting surface on the ankle muscle thickness, proprioceptive sensation, and balance in adults with FAI. Design: Randomized Controlled Trial. Methods: Twenty young people with FAI were randomly assigned to the unstable supporting surface jump group (N=10) and the stable supporting surface jump group (N=10). The intervention was conducted three times a week for eight weeks, and for 30 minutes per session. Trampoline was used as an unstable support surface and the stable support surface was carried out on a regular floor. The thickness of the tibialis anterior muscle and medial gastrocnemius muscle was measured by ultrasonography, and the proprioception of dorsiflexion and plantarflexion was measured using an electrogoniometer. The dynamic balance was also measured with a balance meter. Results: The the muscle thickness of the medial gastrocnemius muscle was significantly higher in the stable supporting surface jump group than in the unstable supporting surface jump group (p<.05). Furthermore, the plantar flexion proprioception and dynamic balance were significantly improved in the unstable supporting surface jump group than in the stable supporting surface jump group in the intergroup comparison (p<.05). Conclusions: The conclusion has been reached in this study that the jumping exercise on the unstable supporting surface could be a more effective in improving FAI than the regular surface.

Purpose: The purpose of this study was to determine the effect of proprioceptive neuromuscular facilitation (PNF) abdominal muscle strengthening exercise on the activity, posture, and body function of clients with abdominal muscle weakness after cesarean section. Methods: PNF abdominal muscle strengthening exercise was applied to one patient with abdominal muscle weakness after cesarean section. PNF abdominal muscle strengthening exercise was applied five times a week for four weeks. The 5-time supine-to-long sitting test (5-TSLST) and supine-to-stand test (SST) were used to measure activity, and the pelvis tilt angle test (PTAT) and anterior head translation test (AHTT) were used to measure posture. Body function was assessed using the transverse abdominis muscle strength test (TAMST), the internal oblique and external oblique muscle strength test (IOEOMST), and the rectus abdominis muscle strength test (RAMST). Results: Activity, posture, and body function were improved post-intervention. Conclusion: The study verified that PNF abdominal muscle strengthening exercises are effective when applied to patients with abdominal muscle weakness after cesarean section. The findings of this study provide useful data for future interventions in patients with abdominal muscle weakness after cesarean section.

Purpose: The purpose of this study was to investigate the influence of opposite lower extremity lateral muscle activation by proprioceptive neuromuscular facilitation (PNF) exercise targeting the lower extremities. Methods: Nineteen patients with chronic hemiplegia volunteered to participate in this study. PNF flexion, abduction, and internal rotation patterns; initial, end range, and extension patterns; abduction and internal rotation patterns; and initial and end range patterns were applied to the dominant lower extremity. Activation of lateral muscles (multifidus, gluteus medius, tensor fascia lata, and peroneous longus) of the paralyzed leg was then measured by electromyography (EMG). Results: There were significant differences in lateral muscle activation, depending on the PNF pattern applied, with the differences more significant in flexion, abduction, internal rotation, and end range patterns. Conclusion: PNF flexion, abduction, and internal rotation patterns can improve lateral muscle activation of one leg in the standing position in the gait cycle.

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.

Background: The purpose of this study is on finding the effects of the lumbar stabilization exercise applied with the proprioceptive neuromuscular facilitation technique (PNF) to the balance and the gait of chronic stroke patients. Methods: An experiment was conducted using two sets of behavioral measures with 30 chronic stroke hospitalized patients in the rehabilitation center located in Incheon city. The 15 participants in group A were instructed to apply the traditional exercise therapy. And the other 15 participants were assigned to apply the lumbar stabilization exercise with the PNF technique. It was conducted for 30 minutes per three days for six weeks, which had eighteen times. Using the balance system, it was checked about the static and dynamic balance. Using the Gaitrite, it was checked about the ability of the gait. Results: There was a better effect on both groups especially with the static balance. Those who were applied the lumbar stabilization exercise with the PNF technique had a better result on the dynamic balance and the gait than those applied the traditional exercise therapy. Conclusion: This research shows that the Lumbar Stabilization Exercise applied with the PNF technique is more effective on dynamic balance and the gait performance ability of the chronic stroke patients.

Purpose : The purpose of this study was to investigate the effect of abdominal muscle strengthening exercise on abdominal muscle strength and respiratory function in stroke patients. Methods : The subjects were 14 stroke patients (10 males, 4 females) hospitalized at W rehabilitation hospital in Busan City and randomly assigned to 7 exercise groups and 7 control groups. Exercise was performed in combination with an upper and lower extremity pattern of proprioceptive neuromuscular facilitation. Measurements of abdominal muscle strength and respiratory function were made before intervention and 4 weeks after intervention. Abdominal muscle strength was assessed using a digital manual dynamometer, and respiratory function was assessed by spirometry. The collected data were analyzed with a paired t-test and independent t-test and the significance level was set as α =.05. Results : The results showed that applying abdominal muscle strengthening exercise to stroke patients showed a significant increase in abdominal muscle strength and a significant difference between groups (p<.05). Maximal-effort expiratory spirogram (MES) readings were significantly increased in forced vital capacity (FVC), and forced expiratory volume in one second (FEV₁), in the exercise group, and there were a significant differences between the groups in terms of FEV1 (p<.05). Slow vital capacity (SVC) was significantly increased in vital capacity (VC), tidal volume (TV), inspiratory reserve volume (IRV), and expiratory capacity (EC), and there were significant differences between the groups in VC, TV, expiratory reserve volume (ERV), EC, and inspiratory capacity (IC) (p<.05). Conclusion : Abdominal muscle strengthening exercise was effective in the abdominal muscle strength of stroke patients, and it was confirmed to have a positive effect on the enhancement of respiratory function. Therefore, it seems that exercise programs for stroke patients with respiratory weakness should include abdominal muscle strengthening exercises.

Purpose: The purpose of this study was to compare the intramuscular activation of the scapular stabilizing muscles and the upper trapezius/middle serratus anterior (UT/MSA) ratios during shrug exercise and proprioceptive neuromuscular facilitation (PNF) scapular pattern exercise. Methods: The participants of this study were 13 young adult men who voluntarily consented to participate in this experiment after listening to its purpose and methods. All participants were instructed on maximal voluntary isometric contraction and scapular exercises. The intramuscular activation of the upper trapezius (UT), lower trapezius (LT), middle serratus anterior (MSA), and lower serratus anterior (LSA) muscles while performing scapular exercises in a side-lying position were measured using surface electromyography. To analyze the muscle activation and UT/MSA ratio between the two exercises, a one-way repeated ANOVA was performed. Post-hoc analyses were conducted using Tukey's multiple comparison and analysis. Hamstring flexibility for each group was measured by a passive straight leg raising test. Results: The shrug exercise showed significantly higher UT activation compared to PNF anterior elevation and posterior elevation scapular patterns. The PNF scapular anterior elevation pattern showed significantly higher serratus anterior activation than the shrug exercise. Additionally, the UT/MSA ratios were significantly lower in the PNF scapular anterior elevation pattern than in the two exercises. Conclusion: Although shrug exercise was effective for strengthening UT, the PNF scapular anterior elevation pattern may be effective for strengthening MSA and improving the UT/MSA ratio.

Background: The purpose of this study is to examine the effect of resistance exercise on static and dynamic proprioception by applying elastic bands to the knee flexor, which can be performed earlier than proprioception, a weight bearing pattern. Proprioceptive training may be applied to the early period of recuperation training along with resistance exercise to prevent damage to the knees and the joints in the lower body, as well as the reoccurrence of injury, which is expected to improve the effect of static and dynamic proprioceptive training. Methods: The subjects of this study were 32 men and women in their 20s who volunteered to participate in the experiment which was carried out over the course of 6 weeks from March 14 to April 24 at K Hospital located in Yongin City. They were tested in two groups: the elastic band resistance exercise group (RE: Resistance Excercise Group, n＝17) and the joint motion range exercise group(ROM: Range of Motion Group, n＝15). In this experiment, static and dynamic proprioceptive tests were given to both groups before and after the test. In this study, SPSS Win ver.12.0 was utilized to perform a T-test on the independent samples in order to validate the identical features of subjects in the RE and ROM Group and substantiate the significance as to the difference between both groups before and after the test. Also, a paired T-test was conducted to compare the static and dynamic proprioception of both groups before and after the test. The statistical significance levels were ${\alpha}$＝.05. Results: 1.The static proprioception in both groups, RE and ROM, increased in a statistically significant way after the test(p<.05). 2.The static propriocetion of the RE group increased in a statistically significant way after the test(p<.05). However, the increase of the static proprioception in the ROM group was not statistically significant. 3.Static and dynamic proprioception of the RE group increased significantly more than that of the ROM group after the test(p<.05). Conclusion: The resistance exercise using elastic bands improved the static and dynamic proprioception more than the joint motion range exercise did, reducing the risk of injury by enhancing the location sense of the joints and the sense of motion and shortening the period of recovery from injury. The outcome of the experiment may provide basic data for developing an effective way to reduce the risk of injury among ordinary people and athletes.
