The aim of this study was investigated the effect of orofacial exercise program using smart phone on swallowing function and tongue strength in acute stroke patients with dysphagia. This study participated in sixteen acute stroke patients with dysphagia. All subjects allocated that randomized each eight patients in experimental and control groups. Subjects of both group received to conventional dysphagia therapy during 30 min/day, 5 times per week, for 4 weeks. Experimental group performed additionally that orofacial exercise program using smart phone, supervised under caregivers, during 30 min/day. The outcome measures were the IOPI(: Iowa Oral Performance Instrument), VR(: Vellecula Residue), PSR(: Pyriform Sinuses Residue), MIP(: Maximum Isometric Pressures). In results of study. Both group showed significant improvements after intervention in all assessments(p<.05). In comparison of change score between two groups, experimental group showed significant improvements than control group in PSR and MIP(p<.05). Orofacial exercise program using smart phone suggested that expected to positive effects the reduction of residue in pharynx and improvements of tongue strength in acute stroke patients with dysphagia.

The purpose of this study was to identify cervical stabilized exercise and joint mobilization, the difference between them, and the maximum muscle strength and static muscle endurance of each group after the enforcement to general people. Cervical joint mobilization group refers to interarticular exercise (traction, pressure, glide) using with Kaltenborn technique. 3 classes were divided into 20 people each, cervical joint mobilization and stabilized exercise, and the comparison groups were randomized for the study. Both cervical stabilized exercise and joint mobilization increased maximum muscle strength and static muscle endurance. Patients should be able improve muscle stabilization and deep cervical muscle by using joint mobilization when the patient is unable to exercise on their own.

Purpose : The purpose of this study was to identify the effect of lumbar stabilization exercise (LSE) and isometric lumbar strengthening exercise (ILSE) on lumbar strength and lumbar extension range in healthy young adults. Method : Ten healthy young adults (six males and four females) volunteered to carry out the LSE and ILSE program for two weeks. The subjects were randomly allocated to two groups: the LSE group (n=5) and the LSE plus ILSE group (n=5). The LSE consisted of 20 minutes of exercise related to lumbar stabilization, and the ILSE was composed of five minutes of isometric stabilization exercise with a specific device. Each group exercised three times per week for two weeks. Assessment tools were made using the subjects' isometric lumbar strength and lumbar extension range before and after the interventions. Results : Statistical analysis revealed significant differences in isometric lumbar strength and the lumbar extension range between before and after the interventions in each group (p<.05). Also, the lumbar extension range improved significantly in the LSE plus ILSE group compared to the LSE group; however, there was no statistically significant difference in the two groups' isometric lumbar strength (p>.05). Conclusion : The findings suggest that ILSE might be feasible in clinical settings by offering benefits for lumbar function. Future studies will be continued.

The purpose of this study was to examine the effects of low intensity resistance training speed on body composition, muscle activity and muscle strength in obese middle-aged women. The subjects (n = 12) were randomly assigned to normal resistance training speed group (NSG, n = 6) and slow resistance training speed group (SSG, n = 6). NSG was performed the for 3 sets ${\times}$ 35 times and total 3-s per repetition (eccentric: 1-s, isometric: 1-s, concentric: 1-s), and SSG performed for 3 sets ${\times}$ 15 times and total 7-s per repetition (eccentric: 3-s, isometric: 1-s, concentric: 3-s). Both groups performed the low intensity resistance training at 30% of 1-RM for 105-s per set, rest for 1 min between sets, rest for 3 min between exercises, and 2~3 times per week, for 4 weeks. The body composition, muscle activity and muscle strength were measured before and 4 week after resistance training. WHR at NSG and body fat at SSG were significantly decreased after resistance training compared with before (P<.05). Ｍuscle activity of biceps brachii, vastus medialis and vastus lateralis at both groups were significantly decreased after resistance training compared with before (P<.05, P<.01). Muscle strength of biceps curl and leg extension at both groups were significantly increased after resistance training compared with before (P<.01). However, body composition, muscle activity and muscle strength did not show statistically significant differences between the groups. Our results suggest that body composition, muscle activity and muscle strength should closely related to the performance time of resistance training (development time of muscle contraction), rather than resistance training speed (repetition frequency).

Purpose: To measure the cervical isometric force generation capacity of men and women, IsoTract was used. Also the aim of this study was to compare manual muscle testing with isometric muscle strength in women. Methods: Forty seven healthy subjects(25 men, 22 women; age range, 18-29) were recruited in two sessions, one for flexion and the other extension. The cervical strength was measured using a force measuring device as IsoTract. Results: Cervical isometric strength was found to be measure for flexion(27.78 Ibs maximum and 24.52 Ibs average) and extension(33.22 Ibs maximum and 29.90 Ibs average) in mans. And isometic muscle strength for women exerted significantly higher in the grade 4 over than in the grade 3 in women. Conclusion: We concluded that there were difference in isometric muscle strength for the grade of manual muscle testing. So this findings may assist in the measure of whole body muscle strength.

Purpose : To compare the effect between isometric exercise group(n=10) and electrical stimulation therapy group(n=10) on improvement of biceps brachii muscle strength. Methods : The experiments were performed for 4 weeks and three times a week. The participants of this study were 20 students(10 male, 10 female) who had not any medical problems. We divided into the two groups. One group received isometric exercise and the other group received EST for 4 weeks. The biceps brachii muscle strength was evaluated by making use of the KIN-COM. Results : The results were as follows 1. One group which received isometric exercise increased 36% for biceps brachii muscle strength. 2.The other group which received EST increased 54% for biceps brachii muscle strength. Conclusion : The results of this study showed that EST group was more effective than isometric exercise group.

The aim of this study was to determine the normative strength value for cervical flexors, extensors and right lateral flexors, left lateral flexors to provide a guideline for rehabilitation of cervical radiculopathy patients. The isometric evaluation of cervical flexors, extensors and lateral flexors by using the Hand-held dynamometer was performed on 50 males and 50 females. The result were as follows. The average cervical muscle strength were 5.7 kg in flexor. 10.5 kg in extensors, and 6.6 kg in right lateral flexor, 6.5 kg in left lateral flexor. There was statistically significant difference between the cervical flexors and extensors(p<0.01) but no significant difference between right lateral flexor and left lateral flexor. There was statistically significant difference between male and female(p<0.01). When one of cervical muscle was strong, also the others did in subjects(p<0.01) and the body weight was significantly releated to the cervical muscle strength(p<0.01).
