  • The purpose of this study was to examine the differentiation of proprioception, invertor and evertor muscle strength, and time to peak torque at a velocity of $300^{\circ}/sec$ of the ankle joint in people with or without functional ankle instability (FAI). Nineteen subjects with a history of ankle sprain participated. All subjects were divided into FAI group ($n_1=9$, Cumberland ankle instability tool (CAIT)${\leq}24$) and a control group ($n_2=10$) based on their CAIT scores. Isokinetic dynamometer was used to measure the sense of active joint position of the ankle at mid-range and end-range of an inversion motion and invertor as well as the evertor muscle strength and time to peak torque at $300^{\circ}/s$. The FAI group showed a statistically reduction in invertor and evertor muscle strength and time to peak torque when compared to the control group (p<.05). Muscle strength and time to peak torque of the invertor and evertor, as well as the sense of active joint position at end-range were also lower in the FAI group than in the control (p<.05). Correlations between CAIT score and position sense at end-range (r=-.577) and invertor muscle strength (r=.554) were statistically significant (p<.05). Individuals with FAI showed reduction in invertor and evertor muscle strength and recruitment time as well as in proprioception of the ankle joint. Thus, proprioception and invertor and evertor muscle strength of the ankle joint at fast angular velocity may be investigated when examining and planning care for individuals with FAI.

  • In this study, six grip spans (45mm-65mm) were tested to evaluate the effects of handle grip span and user's hand size on maximum grip strength, individual finger force, and subjective ratings of comfort using a digital dynamometer with individual force sensors. Forty-six males were assigned into three hand size groups according to their hand lengths. Results showed that overall 55mm and 50mm grip spans were the most comfortable sizes and associated with the highest grip strength in the maximum grip force exertions, whereas 65mm grip span was rated as the least comfortable size as well as the lowest grip strength. In the interaction effect of grip span and hand size, small and middle hand sized participants rated the best preference and the least preference grip spans differently with large hand sized participants. With respect to the analysis of individual finger force, the middle finger force was the strongest and the highest contribution to the total finger force, followed by ring, index and little fingers. In addition, it was noted that each finger had a different optimal grip span for exerting maximum force resulting in a bowed contoured shaped handle for two-handle hand tools. Thus, the grip spans for two-handle hand tools might be designed according to the users' hand and finger anthropometrics to maximize performance and subjective perception of comfort.

발목 감각-운동과 엉덩 관절 근력 강화 통합 훈련 프로그램이 기능적 발목 불안정성 대상자의 정적균형과 동적 균형 및 근력에 미치는 영향 (Effects of Ankle Sensorimotor Training Program Combined with Hip Strengthening Exercise on Muscle Strength, Static Balance, and Dynamic Balance in Individual with Functional Ankle Instability)

  • PURPOSE: This study examined the comparative effects of an ankle sensorimotor training program combined with hip strengthening exercise (ASTPCHSE) and ankle sensorimotor training program (ASTP) alone on muscle strength, static balance, and dynamic balance in individuals with functional ankle instability. METHODS: Sixteen research participants with functional ankle instability were enrolled in this study. The participants were divided randomly into the ankle sensory motor training program group and the ankle sensory motor training program combined with the hip strengthening exercise group. Each group performed a series of exercise programs two times per week for four weeks. The Cumberland ankle instability tool (CAIT) was used to measure the participants' functional ankle instability. A Balance trainer 4 was applied to assess the static and dynamic balance, and a Primus RS multimodal dynamometer was used to evaluate the muscle strength. RESULTS: No significant differences in static balance, dynamic balance, and muscle strength were found between the ASTP and ASTPCHSE groups (p > .05). On the other hand, the dynamic balance and muscle strength improved in the ASTP and ASTPCHSE groups after the intervention (p < .05). The static balance was not enhanced in both groups after the intervention (p > .05). CONCLUSION: Ankle exercise and an ankle sensorimotor training program combined with hip strengthening exercise are effective in improving muscle strength and dynamic balance in individuals with ankle instability. On the other hand, there are no meaningful differences between ankle exercise and ankle and hip combined exercise.

  • 목적 : 성인 및 노인 분야에 종사하는 작업치료사를 대상으로 평가도구 사용 동향을 알아보고자 하였다. 연구방법 : 작업치료사를 대상으로 일반적 특성, 평가도구 사용 대상, 평가 시간 및 주기, 영역별 평가도구 사용 동향, 평가도구 사용 및 교육에 대해 설문조사를 실시하였다. 평가도구 영역은 Occupational Therapy Practice Framework (OTPF)에 따라 작업의 Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), 놀이 및 여가 영역과 클라이언트 요인의 인지 기능, 운동 기능, 심리사회 영역으로 구분하였다. 설문에 응답한 98명의 자료는 SAS 9.4를 사용하여 빈도 분석과 일원배치 분산분석을 하였다. 결과 : 설문에 참여한 작업치료사는 대학병원과 종합병원(40.82%)에 가장 높은 빈도로 근무하고 있었다. 환자 한 명당 소요되는 평가 시간은 30분 미만이 62.25%, 재평가 주기는 1~3개월 미만이 68.38%로 가장 높은 빈도를 보였다. 평가도구의 영역 별 사용 빈도는 작업의 ADL은 Modified Barthel Index (94.90%), IADL은 Canadian Occupational Performance Measure (31.63%), 클라이언트 요인의 인지기능은 Mini-Mental Status Examination (89.80%), 시지각은 Motor-free Visual Perception Test (56.12%), 치매는 Global Deterioration Scale (63.27%), 운동 기능은 Jamar Dynamometer & Pinch Gauge (59.18%), 연하는 Video Fluoroscopic Swallowing Study (28.57%), 이학적 검사법은 Range of Motion (59.18%), 심리사회는 Geriatric Depression Scale (33.67%)을 가장 높은 빈도로 사용하고 있었다. 결론 : 본 연구를 통해 성인 및 노인 분야의 평가도구 사용 동향과 그 근거를 확인하였다. 이는 작업치료학과 교육과정 및 보수교율 등 전문성 강화를 위한 정보로 활용될 것으로 기대된다.
