The objectives of this study were to investigate effects of physical activities in a hospitalized frail elderly people. 31 frail elderly patients were assigned to one of two groups: an exercise group (n=17, 76.35±1.66yrs) and a control group (n=14, 75.29±1.77yrs). The exercise group carried on gymnastic program for 20 minutes, twice a day, 5 times per week for 8 weeks. Timed up and go (TUG) test, Functional reaching test (FRT), flexibility, short physical performance battery (SPPB) were evaluated at 0 weeks, 4 weeks, 8 weeks. There were significant exercise-induced improvements in FRT, flexibility, standing balance in SPPB from pre to post tests (p<.05); but not in TUG, gait speed, chair stands in SPPB (p>.05). These results suggest that gymnastic program can improve physical function in hospitalized frail elderly people. From these results, it can be concluded that higher activity of daily living level would contribute to a lifestyle of more engagement in exercise or physical activity. 이 연구의 목적은 노인체조가 노인요양병원 입원환자의 신체기능에 미치는 영향을 알아보고자 하였다. 31명의 허약한 노인들이 연구에 참여하였으며 운동군(n=17, 76.35±1.66yrs)과 대조군(n=14, 75.29±1.77yrs)으로 분류되었다. 운동군은 일일 20분, 1일 2회, 주5회의 노인체조 프로그램을 8주간 수행하였다. 신체기능을 평가하기 위해 일어나 걸어가기검사(Timed Up & Go test: TUG) 검사, 기능적 뻗기검사(functional reaching test: FRT), 유연성검사, 간편신체수행검사(short physical performance battery: SPPB)를 운동시작 전, 시작 4주후, 8주후에 측정하였다. 운동수행 후 운동군에서 기능적 뻗기검사, 유연성검사 그리고 SPPB검사 중 균형검사에서 통계적으로 유의한 증진이 있었다(p<.05). 이러한 결과로 볼 때, 체조프로그램이 노인요양병원에 입원한 허약한 노인의 신체기능을 유지 및 증진시킬 수 있을 것으로 생각된다.

Purpose: The purpose of our study was to evaluate the effects of an exercise program on activities of daily living (ADL), balance and cognition in elderly individuals with Alzheimer’s disease and vascular dementia. Methods: Thirty-two patients with mild to moderate cognitive impairment were assigned to one of two groups: an exercise group (n=16) and a control group (n=16). The exercise group carried on regular exercise for 60 minutes a day, 4-5 times per week for 8 weeks. The exercise group participated in an exercise program (treadmill training and physical training). ADL, balance and cognitive function were evaluated before and at the end of the program using the Korean modified Bathel Index (K-MBI), the Functional independence measure (FIM), the Berg balance scale (BBS), the Balance performance monitor (BPM), and the Mini mental state examination (MMSE) in both groups. Results: There were significant exercise-induced improvements in ADL and Balance from pre to post tests; but not in MMSE. Conclusion: Exercise programs can improve ADL and balance in elderly with Alzheimer’s disease and vascular dementia.

본 연구의 목적은 파킨슨병 환자의 청각 신호에 따른 보행 시, 상지 스윙의 비대칭과 진폭에 미치는 영향을 알아보기 위함이다. 연구의 대상자는 초기 파킨슨병으로 진단받은 14명의 환자로, 청각 신호(빠른 속도, 일반적인 속 도, 느린 속도)를 무작위 순서로 제공하여 보행을 실시하였다. 청각 신호 속도는 전자 메트로놈을 이용하여 대상자의 자연스러운 보행 속도보다 ±20% 속도를 적용하였다. 각각의 속도에 따른 청각 신호를 적용한 보행을 실시하는 동안, 동작분석기를 사용하여 보행 시 상지 스윙의 운동학적 변수를 비교 분석하였다. 정상 속도의 보행 시 파킨슨병 환자 의 양측 상지 스윙 진폭의 비교에서는 더 많은 영향을 받은 쪽(MAS)의 상지 스윙 진폭에서 유의한 감소가 나타났다 (p<.05). 청각 신호 속도에 따른 보행 시의 비교에서는 빠른 속도의 청각 신호를 적용한 보행 시 상지 스윙의 유의한 증가가 나타났다(p<.05). 본 연구의 결과를 통해 파킨슨 환자의 보행 시 양측 상지 스윙의 비대칭을 확인할 수 있었 으며 또한 보행 시 빠른 청각 신호를 적용하는 경우, 파킨슨병 환자의 상지 스윙을 증가시켜 자연스러운 보행양상을 유도할 수 있으므로 중재 시 필요에 따라 적절한 속도의 청각 신호를 적용하여 보행훈련에 적용할 수 있을 것으로 생각된다. A recent study reporting significantly reduced symmetry in arm swing amplitude in early Parkinson’s disease (PD), as measured during gait by auditory cues velocity, led to this investigation of arm swing symmetry and amplitude in PD. The subjects were 14 elderly patients diagnosed with PD. Patients were measured of three conditions performed in random order: slow, general, fast. The auditory cue velocity consisted of a metronome beat ±20% than the subject’s general gait speed. Using a motion analysis measurement system, changes in kinematic variables were compared to arm swing analysis. PD groups showed a highly significant reduction of the arm swing amplitude on the more affected body side(MAS)(p<.05). Comparison between the auditory cues velocity, there was a significant increase arm swing amplitude in fast velocity gait than slow and general velocity gait(p<.05). We conclude that motion analysis during gait by auditory cues velocity allows reliable investigation of asymmetric arm movements in early PD patients which attenuate with ongoing disease. The measurement of limb kinematics during gait by auditory cues velocity can broaden our methodological line-up for the analysis of complex motor programs in movement disorders.

손호희(Ho-Hee Son),김은정(Eun-Jung Kim) 한국콘텐츠학회 2013 한국콘텐츠학회논문지 Vol.13 No.10

본 연구의 목적은 노인과 정상 성인의 보행경로 너비에 따른 보행 시, 시?공간적 보행 변수의 변화를 알아보기 위함이다. 연구의 대상자는 낙상의 경험이 없는 건강한 노인 20명과 20대 성인 18명으로 하였으며, 3가지 다른 너비의 보행경로(평상시 보행(usual walking), 좁은 너비 보행(narrow base walking), 한 줄 보행(centerline-guided walking)에서 보행을 실시하였다. 평상시 보행은 보행경로에 제한을 두지 않았고, 좁은 너비 보행은 각 대상자의 양측 ASIS 사이의 거리를 1/2로 나눈 너비를 보행경로로 설정하였으며, 한 줄 보행은 보행경로 중앙에 한 줄을 표시하여 보행을 실시하였다. 보행을 실시하는 동안, GAITRite system을 이용하여 시?공간적 보행 변수의 변화를 비교 분석하였다. 보행경로 너비에 따른 시?공간적 보행 변수 비교에서 20대 성인은 모든 변수에서 유의한 차이를 나타내지 않았으나, 노인의 경우 보행속도, 분속수, 양 뒤꿈치 사이 기저면, 기능적 보행지수가 통계적으로 유의하게 감소하였다(p<.05). 본 연구의 결과를 통해 노인은 20대 성인에 비해 보행경로의 너비가 좁아질수록 낙상에 대한 두려움으로 인해 보행 변수에 영향을 미친다는 것을 확인할 수 있었으며, 이를 통해 노인의 낙상 예방 훈련을 위한 적절한 보행너비에 대한 이론적 근거를 제시할 수 있을 것으로 생각된다. The purpose of this study was to investigate the changes in temporospatial variables in healthy elderly and healthy adults during usual walking, narrow base walking and centerline-guided walking. Twenty healthy elderly and nineteen healthy adults were participated in this study. In each conditions, the subjects were walked on a 6m walkway at comfortable self-selected speeds under three conditions : (1) usual walking, (2) walking within a 50% of the distance between the subject’s ASIS (3) walking along a centerline. GAITRite system was used for kinematic analysis to assess the temporospatial variables. There were no significant changes in healthy adults(p>.05), but walking speed, cadence, H-H base support, functional ambulation performance were significantly decreased progressively as pathway narrowed in elderly adults(p<.05). The results show that elderly people had more difficulty with walking on narrow pathway for fear of falling. This study provides data for use in basic research into safe walking and preventing falling for elderly.

Purpose Deep squatting is a common position for Asians during activities of daily living. The purpose of this study is to investigate that ankle joint could contribute during deep squatting. Methods 44 healthy normal participants(20 men, 24 women) were recruited for this study. Whether they were able to perform the deep squat position with their heels on the ground or not, participants allocated into two groups (referred to as heels on ground(HG) squat(n=22(13 men, 9 women)), heels off(HO) squat(n=22(7 men, 15 women)). Results In this study, active/passive ankle joint dorsiflexion range of motion and static balance were assessed. There were significant difference in ankle joint dorsiflexion ROM except right ankle passive ROM. Also heels off squat group showed a significant reduction in static balance. Conclusion These findings show that individuals who can`t perform the deep squat position exhibit reduced ankle ROM and static balance. Thus, deep squat position might be recommended as a simple task to evaluate ankle joint flexibility and static balance.

Purpose: The purpose of this study was to investigate the effect of microcurrent on fatigue of muscles in people who were flat-footed during gait. Methods: 10 flat-footed university students volunteered to participate in this study. 10 flat-footed subjects were divided into 2 groups, one group was experimental group of 5subjects(This group put on microcurrent induction shoes but the subjects were not able to feel the current.) and the other group was the control group of 5subjects(This group put on the general shoes which were similar in shape but microcurrent was not induced.) to perform double blind test and random sampling. Their gait muscle fatigue of 6 regions (vastus medialis, gastrocnemius, tibialis anterior, biceps femoris, erector spinae, and rectus abdominis muscle.) was measured by EMG MP150, Delsys Inc Boston, USA during walking and then they carried out the Harvard step with a platform (It was a arbitrarily made wooden platform of 100cm long, 50cm wide, 60cm high. They carried out climbing it for one second and descending it for one second by using the Metronome program, total 5minutes) for 5minutes. Right after that, the subjects walked on a treadmill at a speed of 4km/h for 10minutes and then their gait muscle fatigue of 6regions was assessed while they were walking on the ground as equally as before exercise. Results: The experimental group has resulted in lower average differences in gait muscle fatigue before and after exercise than those of the control group average 12.24Hz(P=0.009) at vastus medialis, average 8.52Hz(P=0.016) at gastrocnemius, average 9.16Hz(P=0.009) at tibialis anterior, average 8.66Hz(P=0.047) at biceps femoris, average 7.53Hz(P=0.016) at erector spinae, and average 7.80Hz(P=0.047) at rectus abdominis. All of the assessments of muscles have shown significant difference statistically. Conclusions: This result has shown that the use of micro current could decrease gait muscle fatigue of flat-footed people. It is recommended to use a microcurrent to reduce their gait muscle fatigue.

Purpose: The aim of this study was to present specific criteria for setting goals for hand rehabilitation by comparing the degree of difference in grip force, coordination, and dexterity between the dominant and non-dominant hand according to gender. Methods: We recruited 100 healthy adults in their 20s and 30s. A handheld digital dynamometer was used to evaluate the grip force of each of the dominant and non-dominant hand, a chopsticks manipulation test was used to evaluate coordination, and the Purdue Pegboard test was used to evaluate agility. Results: In all subjects, the grip force, coordination, and dexterity showed statistically significant difference (p <0.01) between the dominant and non-dominant hand. In the comparison according to gender, both male and female dominant and non-dominant hands showed statistically significant differences in grip force, coordination, and dexterity (p <0.01). In the comparison according to grip force, there was a statistically significant difference between the dominant and non-dominant hand, and men showed stronger result values in both hands compared to women (p <0.01). In the comparison according to coordination, there was no statistically significant difference between the dominant and non-dominant hand in men and women (p >0.05). In the comparison according to dexterity, there was a statistically significant difference between the dominant and non-dominant hand, and women were shown to be faster in performance time with both hands, compared to men (p <0.01). Conclusion: Differences according to gender exist in grip force and dexterity but not coordination, and differences between dominant and non-dominant hand exists across all measurements. The results suggest setting a recovery goal according to dominance and gender during rehabilitation of hand function.
