The purpose of this study was to investigate the effect of watsu therapy on muscle tone in adult hemiparesis patient after stroke. The subject was a 66 year old patient with left hemiparesis whose self gait was independent with minimal assist. The subject was ambulatory with some degree of limitation and demonstrated a little tremor and asymmetry in the body. A multiple treatment design(A-B-C-B) for a single-subject research was used for this study. The watsu therapy consisted of basic moves, head cradle, underfar leg, near leg cradle in watsu I (transition flow), for 25 minutes, which lasted 12 sessions for a total 21 sessions. A baseline was conducted for a first time and a general ROM exercise was conducted after the first watsu therapy. Tone assessment scale was tested : 1. posturing at rest 2. response to passive movement 3. associated reaction Comparing to the baseline and general ROM exercise, The results showed that the watsu therapy had some positive effects on improvement of three tests and there was a more positive effects of both response to passive movement and associated reaction.

The purpose of this study was to investigate the effects of virtual reality (VR) therapy with compensation inhibition and feedback (CIF) on upper extremity function in chronic stroke patients. Seven chronic stroke patients participated in this study, which was a randomized controlled trial with a crossover design. Self upper extremity exercise, conservative VR therapy, and VR therapy with CIF were performed for one hour per session, 5 times per week, over a 3 week period. The main outcome measures involved range of motion (ROM) including shoulder, elbow, and wrist joints, a Manual Function Test (MFT), and a Motor Activity Log (MAL). Data were calculated as posttest and pretest changes in every session and were analyzed using Friedman and Wilcoxon signed-rank tests at p<.05. The results were as follows: 1) Statistically significant increase in ROM measurements of shoulder and elbow joints were seen with VR therapy with CIF compared to VR therapy and self upper extremity exercise (p<.05), whereas no significant increasing was noted for the wrist joint (p>.05). 2) Statistically significant increase in the MFT was seen with VR therapy with CIF compared with VR therapy and self upper extremity exercise (p<.05). 3) VR therapy with CIF also resulted in statistically significant increase in both activity of use (AOU) (p<.05) and quality of movement (QOM) (p<.05) on the MAL test when compared with VR therapy and self upper extremity exercise, respectively. In conclusion, VR therapy with CIF was more effective than conservative VR therapy and self upper extremity exercise in improving the upper extremity function in hemiplegic patients with chronic stroke.

The purpose of this study was to investigate the effects of post-isometric contraction stretching combined with antagonist muscle contraction on muscle strength and flexibility using electromyography (EMG) and ultrasound imaging (USI). Healthy adults were recruited. The static stretching and post-isometric contraction stretching combined with antagonist muscle contraction method was applied to each groups, respectively. Muscle activation using surface EMG, range of motion (ROM) using goniometer, and pennation angle (PA) using USI were measured in the hamstring muscle in pre- /post-tests. Data was presented descriptive statistics, paired t-test, and independent t-test through SPSS 12.0. The paired t-test showed that the amplitude of muscle activation was significantly improved at post-isometric contraction stretching combined with antagonist muscle contraction (p=0.00), whereas was not significant at static stretching (p=0.44), the ROM and the PA were significantly improved both groups, respectively (p=0.00). The independent t-test was significant improved at post-test between two groups (p=0.05). Our findings suggest that the post-isometric contraction stretching combined with antagonist muscle contraction was effective in management of muscle strength and flexibility compared to the static stretching. Additionally, the PA using USI was useful of measuring the flexibility.

The purpose of this study was to investigate the effects of aquatic exercise on gait distance and gait speed of patients with central nerve system disease(PCNS). A total of 40 subjects voluntarily participated in this study, twenty in each of the two exercise groups: one for aquatic exercise(AE), and the other for general exercise(GE). Each group was tested with gait analysis(Walkway MG-1000), which was performed(provided) in pre-/post interventions. The parameters used for gait distance were stride length, step length, step width, and foot angle, and for gait speed were stride time, stance time, swing time, double stance time, gait speed, and cadence. Data was presented in descriptive statistics, paired t-test, and independent t-test through SPSS 12.0. AE was significantly improved in gait distance except foot angle(p<0.05) as well as in gait speed(p<0.05). Our findings suggest that AE is effective in management of gait distance and gait speed on PCNS. However, it should be complemented for a specific movement such as foot angle as well as in a non-gravity environment as in water.

The purpose of this study was to investigate the effects of Evjenth-Hamberg stretching on the active range of motion (ROM) of the hip joint and the pennation angle of the semitendinosus muscle. Eighty healthy adults articipated in this study. The active ROM of the hip joint was measured by a goniometer and the pennation angle of the semitendinosus muscle was measured by ultrasonographic imaging (USI). Both ROM and pennation angle were recorded before and after the static stretching and the Evjenth-Hamberg stretching, respectively. Data were analyzed using paired t-test and independent t-test at p<.05. The results were as follows: 1) The active ROM of the hip joint increased significantly after both stretching interventions compared with the baseline (p<.001). However, the active ROM of the hip joint increased significantly in Evjenth-Hamberg stretching compared with static stretching. 2) The pennation angle decreased significantly after both stretching interventions compared with the baseline (p<.001). However, the pennation angle decreased significantly in Evjenth-Hamberg stretching compared with static stretching. 3) Reliability data showed that there was a high consistency in USI measurements ICC=.978. Our findings suggest that the Evjenth-Hamberg stretching was more effective than static stretching in increasing the active ROM of the hip joint and decreasing the pelmation angle of the semitendinosus muscle.

This study compared the effects of craniocervical flexion exercise with conservative cervical flexion exercise in workers with chronic neck pain. Subjects were randomly allocated to two groups: control (n=20) and experimental group (n=20), respectively. The conservative exercise for the control group consisted of cervical flexion exercise, whereas the experimental group performed a craniocervical flexion exercise. To compare the two groups, the visual analogue scale (VAS) for a pain, neck disability index (NDI) for a neck disability scale, and cross sectional area (CSA) of longus colli muscle using ultrasound image were assessed on pre-intervention, post-intervention, and 2 weeks follow-up. 2-way repeated ANOVA was used with Bonferroni post-hoc test. (1) There were significant main effects (within and between groups) (p<0.05) and interaction effect (p<0.05) in VAS. Post-hoc test revealed that there were significant differences in all pair-wise comparisons. (2) There were significant main effects (within and between groups) (p<0.05) and interaction effect (p<0.05) in NDI. Post-hoc test revealed that there were significant differences between pre-intervention and post-intervention, pre-intervention and 2 weeks follow-up. (3) There were significant main effects (within and between groups) (p<0.05) and interaction effect (p<0.05) in CSA of longus colli muscle. Post-hoc test revealed that there were significant differences in all pair-wise comparisons. The findings indicate that craniocervical flexion exercise are more effective for improving pain, neck disability, and CSA of longus colli muscle than cervical flexion exercise in workers with chronic neck pain.

PURPOSE: In adults with hamstring tightness, stretching is considered a therapeutic exercise that improves flexibility. However, previous studies have reported efficacy of numerous methods, and are inconclusive in determining the most effective stretching techniques. This study aims to compare the outcomes of Evjenth-Hamberg stretching (E-HS), proprioceptive neuromuscular facilitation stretching (PNFS), and static stretching (SS), on muscle tone and flexibility. METHODS: A total of 30 subjects were assigned to each of the three stretching groups:; E-HS (n1 = 10), PNFS (n2 = 10), and SS (n3 = 10). Muscle tone of the hamstring muscle, active knee extension (AKE), and passive knee extension (PKE) were assessed by range of motion. RESULTS: After the intervention, statistically significant differences were obtained between groups for muscle tone (p < .05). The post hoc test, showed statistically significant differences in muscle tone between the E-HS and PNFS groups (p < .05), and PNFS and SS groups (p < .05). Post hoc test after intervention, also revealed statistically significant differences in flexibility (p < .05) between the E-HS and PNFS groups (p < .05), E-HS and SS groups (p < .05), and PNFS and SS groups (p < .05). Moreover, a statistically significant difference was observed in PKE scores between the E-HS and SS groups (p < .05), and PNFS and SS groups (p < .05). CONCLUSION: This study indicates that E-HS may be the most effective stretching technique for muscle tone and flexibility, in adults with hamstring tightness.

The purpose of this study was to assess the level of quality of life and related factors among the elderly in Korea. In particular, we focused on factors affecting the quality of life of the elderly in long term care. We used the third Korean National Health and Nutrition Examination Surveys (KNHANES) from 2005. We sampled a total of 3,571 (10.5%) elderly from the national survey. We compared the mean of quality of life to socioeconomic status, Activities of Daily Living (ADL), health behavior, and disease variables. We used EuroQol-5D among KNHANES to assess the quality of life. In this study, the mean score of the quality of life among the elderly was 2.57. Logistic regression showed that the elderly who were male, with spouses, with health insurance, and with good ADL levels enjoyed higher quality of life scores and odds ratios than those who were female, divorced, uninsured, and with low ADL levels (p<.05). The quality of life of the elderly was affected by socioeconomic, ADL, health behavior and disease variables. To improve long term care and the quality of life among the elderly, we need detailed research to clarify the effects of these factors.

This study aimed to investigate the effect of differing heel height on static balance and muscle activation of ankle joint during standing. Twenty-one young females volunteered to participate in this study. To measure balance function and EMG activity of tibialis anterior and gastrocnemius muscles, the subjects were asked to perform 1-min standing with eyes open and closed state under 3 different heel heights: barefoot, 3cm, and 7cm each. During the standing, postural sway distance and area, and EMG activity of tibialis anterior and gastrocnemius muscles were significantly augmented with increasing heel height (p<0.05). For comparison between eyes open and closed in terms of postural sway area and EMG activity of tibialis anterior muscle, barefoot and 7cm height conditions respectively showed significant differences as well. The findings indicate that high-heeled shoes may have disadvantages in maintaining balance function because of extra-muscular effort of ankle joint. This study provides useful information that will inform future studies on how heel height affects muscle activity around the ankle joint in aspects of static and dynamic balance.

PURPOSE: This study examined the effect of muscle thickness of the deep cervical flexor muscle, muscle tonicity, and muscle fatigue of the superficial cervical flexor muscle by applying a functional latex pillow to patients with chronic cervical pain. METHODS: An experimental group using a functional latex pillow and a control group using a general pillow were assigned randomly to 30 people. Each pillow was applied in a comfortable lying position in the experimental group and control group. The deep cervical flexor muscle thickness was measured in the longus colli and longus capitus using ultrasonography. The muscle tonicity and muscle fatigue of the superficial cervical flexor muscle were measured separately in the sternocleidomastoid muscle using a myotonometer and electromyography. RESULTS: In the experimental group(functional latex pillow), the muscle tonicity of the superficial cervical flexor muscle like the sternocleidomastoid muscle was significantly lower than that of the control group (general pillow)(p < .01). CONCLUSION: This study suggests that the functional latex pillow may effectively reduce the muscle tonicity of the sternocleidomastoid muscle, which is the superficial cervical muscle, in patients with chronic cervical pain. On the other hand, it was not effective on the muscle thickness of the deep cervical flexor muscle and muscle fatigue of the superficial cervical flexor muscles.
