Purpose: This study examined the improved sensory, hand function, postural balance and activities of daily living (ADL) through somatosensory stimulation, such as the facilitation of functional reaching and tactile, proprioceptive stimulus of the upper limb (UL) and hand. Methods: Seventeen stroke patients having problems with motor and somatosensory deficits were selected in Bobath Memorial Hospital adult rehabilitation center. The patients were divided into two groups; the sensorimotor deficit group (SMDG) and motor deficit group (MDG). Somatosensory stimulation on the UL, physical therapy and occupational therapy were carried out three times a week over a six week these treatments were performed in both group period. To compare each group, the following assessment tools were used: such as tactile detection thresholds (TDT), two point discrimination on the affected side (TPDas), unaffected side (TPDus) stereognosis (ST) manual function test, hand function on the affected side (HFas) and unaffected side (HFus), Postural Assessment Scale for Stroke (PASS) and Korean version Modified Barthel Index (K-MBI). Results: In the SMDG, somatosensory stimulation on the UL was statistically important for TDT, TPDas, TPDus (except for the thener), ST, hand function on HFas, on HFus, PASS length of displacement with foam (LDFSEO), and K-MBI. In the MDG, somatosensory stimulation on the UL was important for TDT, TPDas, TPDus (except index finger) length of displacement with the eyes open, LDFSEO, HFas, HFus, PASS and K-MBI. In addition, there was a significant difference in the PASS between SMDG and MDG. Conclusion: Somatosensory stimulation on the UL affects the sensory, hand function, postural control and ADLs performance.
Purpose : The purpose of this study was to evaluate the effects of the Hahoe mask dance on the gait and muscle activity in the elderly who lived at a elderly welfare facility. Methods : Dancing group was consisted of 20 subjects(over 70 years). The time of measurement was assigned in pre measurement, after 1 month, after 2 months. Subjects was received the Hahoe mask dance for three times a week during 8 weeks. The control group was consisted of 20 the elderly (similar age) who didn't received dancing. Assessment of gait function included the gait velocity, step time, stride, step length, it was analyzed in activity for 4 muscles (rectus femoris, biceps femoris, tibialis anterior, and lateral gastrocnemius). Results : Activities for muscles of control group was decreased in rectus femoris, bieps femoris, however, those of experimental group was increased significantly(p<.05). While control group showed decrease in the gait velocity per second (p<.05), experimental group showed statistically significant increase(p<.05). Control group had a significant long time than that of control group in gait time of right and left foot(p<.05). Control group was a little longer than control group in stride time of right and left foot(p<.05). Step length for control group was shorter than that for experimental group both foots(p<.05). Conclusion : In conclusion, this study confirmed that activities for 4 muscles by EMG have showed significant increases, so we will use a programme of muscle improvement in elderly community welfare faculty. We recommend that further research should explore the degree of muscle activity by larger sample sizes and longer follow-up periods.
PURPOSE: This study aims to provide effects of therapeutic techniques as well as basic materials of safety by comparing and analyzing the effects of hamstring flexibility and dynamic stability of lower lumbar according to Stretching and Massage Techniques to adults with reduced the flexibility of hamstring. METHODS: This study conducted differential diagnosis through sit and reach test(SRT) and Schober test to select subjects who have shortened hamstring without any spinal problem. Selected subjects were divided into two groups randomly; HSG(Hamstring Stretching Group, n=8) and HMG(Hamstring Massage Group, n=8) and they received treatment for 2 weeks. To take statistics, SRT and dynamic view using x-ray were used. RESULTS: On SRT, HSG and HMG showed significant difference between pre and post test. A comparison of the difference value between HSG and HMG, HSG($9.73{\pm}1.78$) has more remarkable outcome than HMG($2.78{\pm}0.56$). Lower lumbar intervertebral disc length test for Intervertebral disc length(IDL)L45 and IDLL5S1 did not show significant differences between two groups and difference value. CONCLUSION: This study showed that stretching is more effective to improve hamstring flexibility than massage technique. Especially, flexibility increase of the hamstring in vertebral stabilization cannot affect improvement possibility will make a flexibility in order and the intervention and stabilization exercise of the spine.
Summary of background data: At the wound from life of the human being very regarding at and a healing process the wound in the portion which is important meantime the many research is accomplished and healing process at the wound the research is small very from the physical therapy territory. Purpose: This study was performed to examine the effects of cold therapy and pulsed ultrasound treatment in the process of acute wound healing.

Methods: We divided twenty Sprague-Dawley rats into four experimental groups of five rats each and treated them for three days after wound creation. Then we extracted tissues from the wounds on day 6th after wound creation and then took them out for hematoxylin-eosin(HE) staining. We measured changes in the length of the wounds every other day. Result: We were able to detect significant statistical differences in the cold therapy and pulsed ultrasound-treated wounds compared with control wounds. We observed tissues through an optical microscope and found the tissues in cold therapy and pulsed ultrasound-treated wounds healed well. Conclusions: Overall results indicated that the use of cold therapy and pulsed ultrasound treatment were effective in the process of acute wound healing.
PURPOSE: Most gait assessment tools are expensive and require controlled laboratory environments. Tri-axial accelerometers have been used in gait analysis as an alternative to laboratory assessments. Many smartphones have added an accelerometer, making it possible to assess spatio-temporal gait parameters. This study was conducted to confirm the reliability and validity of a smartphone-based accelerometer at quantifying spatio-temporal gait parameters of stroke patients when attached to the body. METHODS: We measured gait parameters using a smartphone accelerometer and gait parameters through the GAITRite analysis system and the reliability and validity of the smartphone-based accelerometer for quantifying spatio-temporal gait parameters for stroke patients were then evaluated. Thirty stroke patients were asked to walk at self-selected comfortable speeds over a 10 m walkway, during which time gait velocity, cadence and step length were computed from smartphone-based accelerometers and validated with a GAITRite analysis system. RESULTS: Smartphone data was found to have excellent reliability ($ICC2,1{\geq}.98$) for measuring the tested parameters, with a high correlation being observed between smartphone-based gait parameters and GAITRite analysis system-based gait parameters (r = .99, .97, .41 for gait velocity, cadence, step length, respectively). CONCLUSION: The results suggest that specific opportunities exist for smartphone-based gait assessment as an alternative to conventional gait assessment. Moreover, smartphone-based gait assessment can provide objective information about changes in the spatio-temporal gait parameters of stroke subjects.
PURPOSE: This study compared ankle joint exercise and thigh exercise on the isometric strength of the lower limb and balance ability. METHODS: Twenty-seven subjects were divided into ankle joint exercise (AEG, n=9), tight exercise (TEG, n=9), and control group (CON, n=9). AEG and TEG performed ankle joint and tight exercises three times a week for four weeks. The following were measured before and four weeks after each exercise: isometric strength at knee flexion and extension of the lower limb; isometric strength at ankle plantar flexion and dorsiflexion of the lower limb; static balance of trace length and C90 area; and the dynamic forward, backward, leftward, and rightward balance for each region. RESULTS: The results showed that the isometric strength of plantar flexion (p<.05) was increased significantly in AEG compared to those in TEG and CON. The dynamic leftward (p<.05) and rightward balance (p<.05) were increased significantly in both AEG and TEG compared to that in CON. On the other hand, the static balance of the trace length and C90 area, isometric strength of ankle dorsiflexion, knee flexion and extension of the lower limb, and dynamic forward and backward balance did not show significant differences between the groups. CONCLUSION: Ankle joint exercise improves the isometric strength of plantar flexion compared to tight exercise.
The purpose of this study was to determine the effects of high voltage pulsed current (HVPC) stimulation on wound healing. Thirty-four Sprague-Dawley adult female rats were assigned to experimental and control groups. Each rats were anesthetized with pentotal sodium, and a 10 mm full-thickness incision was made on the back. From 24 hours after surgery, the rats of experimental groups were stimulated with HVPC, $140{\mu}s$, 120 pps, 30-40 V for 30 minutes, daily. The rats were sacrified 2 days, 4 days and 6 days after stimulation, respectively. The skin was removed, and processed for light microscopic examination. The length of incisional wounds were measured by microcaliper, and nucleolar organizer regions were counted under light microscope. For the histological observations the specimens were stained with Hematoxylin and Eosin, Masson Trichrome, Gomori Reticulum and Ag-NOR. There was a significant decrease in the length of incisional wound in experimental group compared with control group at 6 days HVPC stimuation (p<0.05). In experimental group, wound were significant difference (p<0.01) between the duration of post surgery. The mean numbers of nucleolar organizer regions per nucleus were significantly increased in the experimental group at 6 days HVPC stimulation (p<0.05), and were significantly difference (p<0.01) between the duration of post surgery in experimental group. Histological examination of the wound site suggested a more rapid of epithelialization and collagen formation between experimental groups compared with control groups. The result may indicated that the HVPC with $140{\mu}s$, 120 pps, 30-40 V for 30 minutes promoted surgical wound healing in the rat.
PURPOSE: The purpose of this study was to investigate the effect of treadmill walking training using the metronome on the gait pattern. METHODS: A total of 33 healthy persons were studied consisting of 17 female and 16 male in the 20-30 age group. A gait analysis program was installed on a treadmill with a built - in gait analysis sensor and laptop. After 9 minutes of treadmill walking, gait analysis was performed for 1 minute. The mean values of the differences in the step length, angle of COP, separation line standard deviation and step force of the lower legs affecting walking symmetry were calculated for treadmill walking and treadmill walking using the metronome. The Shapiro-Wilk test was used to test the normality of the collected data and a paired t-test was performed to analyze the difference in walking before and after using the metronome. RESULTS: As a result of the analysis, the mean of difference between the measured values of the bilateral lower extremity for step length, angle of COP, separation line standard deviation and step force were statistically significant before and after treadmill walking using the metronome. CONCLUSION: Therefore, the treadmill walking training using the metronome is effective in decreasing the difference in the foot width, gait angle, gait distribution, and foot pressure. Because of this, the treadmill walking training using the metronome has a significant effect on walking symmetry among the elements for correct walking, which is a means for enabling efficient and continuous walking.
Background: Abdominal bracing exercise (ABE) and abdominal hollowing exercise (AHE) improve the lumbar flexibility and pulmonary function in various patients, yet the efficacy of ABE or AHE have not yet been evaluated. Objects: The purpose of this study was to compare the lumbar flexibility and pulmonary function during both ABE and AHE in healthy adults. Methods: The study included 40 healthy adults, who were randomly divided into the experimental group and control group, each with 20 subjects. All subjects performed ABE (experimental group) and AHE (control group). The lumbar flexibility such as trunk flexion test (sitting and standing position) and schober test and pulmonary function such as the spirometer including forced vital capacity (FVC) and force expiratory volume in one second ($FEV_1$) and chest circumference measurement (middle and lower chest) were measured, respectively. Two-way repeated analysis of variance was used to compare the lumbar flexibility and pulmonary function, respectively. Results: No significant effects of lumbar flexibility were observed on trunk flexion test from the sitting position (P=.478) and standing position (P=.096) in the ABE than in the AHE. However, the length of ABE was longer significantly than it of AHE (P=.024). No significant effects of lung function were observed on the FVC (P=.410) and $FEV_1$ (P=.072) in the ABE group than in the AHE group. And also, no significant effects of chest circumference measurement were observed on the inspiration (P=.468) and expiration (P=.563) in middle chest circumference and inspiration (P=.104) and expiration (P=.346) in lower chest circumference. Conclusion: This study indicated that the ABE is only more effective in lumbar flexibility by lumbar length difference than AHE in healthy adults.
PURPOSE: The purpose of this study was to investigate the effect of balance rehabilitation training with the visual cue deprivation on gait function in stroke patients in comparison with balance training without the visual cue deprivation. METHODS: Twenty two stroke patients participated in this study. Patients were randomly assigned to one of the two balance training program with and without the visual cue deprivation. Balance training session for each group lasted 50 minutes, 3 times a week for a total of 6 weeks. Gait function was measured with the Functional Gait Assessment (FGA), the self-selective comfortable gait speed (CGS), the maximal gait speed (MGS), and the Gait Analysis System. Temporal and spatial gait parameters of each evaluation were measured before and after the balance training program respectively. RESULTS: After the program, the visual cue deprivation group improved significantly in the FGA, the CGS, the gait velocity, the step time, the step length, the stride length, and the Functional Ambulation Performance (FAP) in comparison with the balance training group with the visual cue (p<.05). CONCLUSION: The gait function of the participants with the visual cue deprivation showed more improvement after the balance training program compared to the patients group without the visual cue deprivation, Therefore, the balance training program with the visual cue deprivation may be useful for rehabilitation of patients with chronic stroke.
