Purpose : To exam the effects of active ankle range of motion(ROM) exercise on sciatic nerve movement and provide the evidence that use it to patients with hypomobile sciatic nerve as a nerve mobilization technique. Methods : The subjects consist of 32 asymptomatic healthy adults(male; 15, female; 17) who have limited passive straight leg raising(PSLR) ranges below 70 degrees. First, examiner measures PSLR angles at three times. Then, subject was instructed perform the active ankle ROM exercise(dorsiflexion and plantarflextion) at limited angle. After each subject completed the active ankle ROM exercise, return the starting position and examiner measures the PSLR angles at three times again. Results : First, PSLR range was no significant differences between dominant and non-dominant leg(p >.05). Second, active ankle ROM exercise significantly increased PSLR range by mean of degrees(p <.05). Third, there was no learning effects among the measurement trials(p >.05). Conclusion : These data show that active ankle ROM exercise can mobilize the sciatic nerve. Therefore, it can be applied to patients with hypomobile sciatic nerve(sliding dysfunction) as a neural mobilization technique.

The relationships between nutrients intake, physical activity and bone mineral density were investigated in 19 elderly men aged 71-80 years. A trained nutritionist interviewed usual dietary intake and daily activity with a questionnaire, and bone mineral density was measured at the lumbar spine and three regions of the proximal femur (femur neck, Ward's triangle and trochanter) with a Luna DP3 dual photon absorptiometry. The correlations between dietary calcium intake and bone mineral density at the lumbar spine and trochanteric region were significant at P<0.05 and P<0.01 level respectively. the significant correlations were also found between vitamin A(P<0.005), riboflavin(P<0.01), and ascorbic acid(P<0.05) intake and bone mineral density at these sites. Higher physical activity was associated with greater bone mineral density of four sites, but this was not significant. But there were significant relationships between total energy expenditure and bone mineral density of the lumbar spine(P<0.01), femur neck (P<0.05) and Ward's triangle(P<0.05). In this study the results revealed that bone mineral density of the lumbar spine and trochanteric region were associated with dietary calcium intake. And bone mineral density of the femur neck and Ward's triangle were related to physical activity but not to nutrients intake. In conclusion, dietary calcium intake seems to be a important factor for greater bone mineral density. Further evidence will be needed that physical activity protects against bone fracture and osteoporosis in the edlerly.

Purpose: This article provides an overview of current knowledge on the impact of caregiving on the psychological and physical health of family caregivers of intensive care unit (ICU) survivors and suggestions for future research. Methods: Review of selected papers published in English between January 2000 and October 2015 reporting psychological and physical health outcomes in family caregivers of ICU survivors. Results: In family caregivers of ICU survivors followed up to five years after patients' discharge from an ICU, psychological symptoms, manifested as depression, anxiety and post-traumatic stress disorder, were highly prevalent. Poor self-care, sleep disturbances and fatigue were identified as common physical health problems in family caregivers. Studies to date are mainly descriptive; few interventions have targeted family caregivers. Further, studies that elicit unique needs of families from diverse cultures are lacking. Conclusion: Studies to date have described the impact of caregiving on the psychological and physical health in family caregivers of ICU survivors. Few studies have tested interventions to support unique needs in this population. Therefore, evidence for best strategies is lacking. Future research is needed to identify ICU caregivers at greatest risk for distress, time points to target interventions with maximal efficacy, needs of those from diverse cultures and test interventions to mitigate family caregivers' burden.

Purpose: This study examined the difference in the static balance ability according to the visual cues and postural tasks in normal subjects. Methods: Thirty participants (12 male, 18 female; mean age $24.63\pm1.43$ years) stood barefoot on a force platform in a one-legged stance, tandem Romberg stance and tandem Romberg with neck extension stance with a visual cue open and closes. The static balance was assessed by the center of pressure (CoP), surface electromyography root mean square (RMS) of the leg muscles according to the stance position. Results: In the CoP tests, the difference in the unit path length and circumference area was affected by the visual cue according to the stance posture (p<0.01). In the RMS tests, the difference in the tibialis anterior and medial gastrocnemius muscle was affected by visual cue in accordance with the stance posture (p<0.01). Conclusion: The visual cue and postural task affect the balance ability in normal subjects. Therefore, this study provides clinical evidence that the balance and postural control can be improved. Therapeutic intervention, such as an obstacle course, and a lower leg muscle performance program with a change in the base of support can affect the balance and postural control.

The objectives of this study were to compare the quality changes of cheese slices individually packed in four kinds of edible pouches in order to select the most suitable variety for individual packaging. The edible Z2 pouch (zein with oleic acid) was selected as maintaining the best cheese qualities based on the physical and microbiological changes undergone by the samples over 4-week storage at $5^{\circ}C$. The cheese sample individually packed in Z2 inner edible pouch and repacked in a plastic (OPP/LLDPE) outer pouch was not significantly different in physical and microbiological changes from that individually packed in a plastic (OPP/LLDPE) inner pouch and repacked in a plastic (OPP/LLDPE) outer pouch. Therefore, it may be concluded on the basis of the physical and microbiological evidence that the Z2 edible pouch can be used as an inner package for cheese slices when it is inside a plastic outer pouch.

The purpose of this study was to provide experimental evidence and theoretical background for the applicability of bilateral transfer paradigm to the rehabilitation programs for children with hemiplegic cerebral palsy. Children with hemiplegia, which means unilateral motor disabilities, display abnormal motor and postural patterns of the affected side due to hemiparesis, spasticity, and sensory disorders, resulting in a decreased motor abilities of the affected side compared to unaffected side. Accordingly, they tend to rely on the unaffected limb for everyday activities, which further deteriorates the functions of the affected side by causing associated reaction, abnormal postural patterns, and hypertonus. Rehabilitation programs developed for children with hemiplegic cerebral palsy include neurodevelopmental treatment, application of cast or splint to unaffected limb, neuromuscular electrical stimulation, and task oriented model. These programs, however, have several drawbacks, such as discontinuity in treatment effect and psychological hatred to the force use of the affected side. In order to solve these problems and enhance the efficiency of the rehabilitation programs, it is required to maximize the use of the affected side without hatred. Characteristics of the control system, such as temporal coupling and spatial assimilation between limbs and neural crosstalk at different levels of central motor pathway, suggest that the bilateral transfer paradigm may enhance the efficiency of the rehabilitation programs for children with hemiplegic cerebral palsy.

Purpose : This paper focuses on the emerging concept that adult central nervous system neurogenesis can be regulated by various physical activity, enriched environment, and pathological conditions. Neurogenesis-the production of new neuron-is an ongoing process that persists in the adult brain of mammalian, including humans. Result : The adult brain was thought be limited in its regenerative function. However, this concepts changed, recent evidence of neurogenesis in certain adult brain areas such as SVZ(subventricular zone) and SGZ(subgranular zone) in hippocampus, raised possibility for improved treatment for patient with stroke. Neural plasticity has an adaptive purpose, because an ability of the brain to change in response to peripheral stimulation, physical activity, experience, and injury. Conclusions : The major function of the neurogenesis in adult brain seems to be replacing the neuron that die regularly in discrete adult brain regions. These cells are capable of functionally integrating into neighboring neural cells, and reconnecting to the correct neural networks. This review suggest that various intervention, including physical activity, voluntary movement training, skilled forelimb reaching training, and enriched environment, induced neural cell production in certain adult brain, and associated with functional recovery after stroke.

Objective: To determine the correlation among three functional tests: single leg vertical jump (SLVJ), single leg hop for distance (SLHD), and single leg squat (SLSQ). Design: Cross sectional study. Methods: Twenty healthy men (n=10) and women (n=10) with no history of lower extremity dysfucntion participated in this study and performed in university research laboratory. The procedures consisted of a general warm-up, a task-specific warm-up, actual testing, and a cool down. All participants performed the three tests in random order. Each test was performed three times for the dominant and non-dominant lower extremity (LE). SLVJ, SLHD, SLSQ were measured using a standard tape measure. Results: Statistically significant difference was presented between dominant LE and non-dominant LE in each function test (p<0.05). The strongest correlation was between SLVJ and SLSQ, 0.939 and 0.883 for dominant and non-dominant LE, respectively (p<0.05). The weakest correlation was between SLVJ and SLHD, 0.713 for dominant (p<0.05) and between SLSQ and SLHD, 0.739 for non-dominant (p<0.05). Conclusions: There is a strong correlation between SLVJ and SLSQ, suggesting that each test measures similar constructs of function and can be substitutive, while weak correlation between SLSQ and SLHD suggest these two tests do not measure the same functional components and could be paired as outcome measures for the clinical assessment of LE function. It will provide physical therapist with scientific evidence for effective test combination of LE function assessment in clinical practice.

Purpose: The objective of this study was to investigate the effects of Kinesio taping (KT) for balance and gait in patients with stroke through meta-analysis of studies conducted in Korea. Methods: RISS, Science on, and DBPia were the three databases used to collect articles on KT. Keywords such as "Stroke," "Kinesio taping," "Elasticity taping," and "Taping" were used to search for published articles. We systematically searched from the inception of each database to November 2020. Interventions and comparisons were KT and without KT. Outcome measures were the timed up and go (TUG) and 10-meter walking tests (10MWT). Consequently, six studies were selected for the second screening using meta-analyses. Results: Based on the results of the meta-analysis, comparison between patients with and without KT showed that KT was effective for TUG (ES: 2.51, 95% CI: 2.12 to 2.90); however, it was not effective for 10MWT (ES: 0.79, 95% CI: -0.04 to 1.62). Conclusion: The current evidence suggests that KT is more effective than without KT interventions for balance function in post-stroke patients. However, more well-conducted randomized controlled trials are required in the future.

Purpose: This study examined whether there is a difference in motor learning through short-term repetitive movement practice in stroke survivors with a unilateral brain injury compared to normal elderly participants. Methods: Twenty-six subjects who were divided into a stroke group (n=13) or sex-aged matched normal elder group (n=13) participated in this study. To evaluate the effects of motor learning, the participants conducted a tracking task for visuomotor coordination. The accuracy index was calculated for each trial. Both groups received repetitive tracking task training of metacarpophalangeal joint for 50 trials. The stroke group performed a tracking task in the upper extremity insi-lesional to the damaged hemisphere, and the normal elder group performed the upper extremity matched for the same side. Results: Two-way repetitive ANOVA revealed a significant difference in the interactions ($time{\times}group$) and time effects. These results indicated that the motor skill improved in both the stroke and normal elder group with a tracking task. On the other hand, the stroke group showed lesser motor learning skill than the normal elder group, in comparison with the amount of motor learning improvement. Conclusion: These results provide novel evidence that stroke survivors with unilateral brain damage might have difficulty in performing ipsilateral movement as well as in motor learning with the ipsilateral upper limb, compared to normal elderly participants.
