Objective: To investigate a characteristics of short physical performance battery (SPPB) in some Korean rural community and to obtain a preliminary data of SPPB in Korea. Method: A total of 488 persons aged 22 to 82 with no disability, interviewed and administered a SPPB and a balance test using MedianceⓇ. Subjects were divided into 3 groups with high (less than 6 points), medium (7 to 9 points) and low (10 to 12 points) risk groups according to SPPB score. Lower extremity performance was measured using SPPB including assessment of standing balance, a timed 4-m walk, and timed test of rising 5 times from a chair. Chronic condition were ascertained as self-report of past disease history. The relationship between general characteristics of subjects, self-report of past history of disease, limb load asymmetry, postural sway and SPPB score were statistically analyzed. Results: In a multivariate analysis, older age, lower educational background and high body fat mass were associated independently with poor performance. In a multivariateanalysis of subjects aged 60 or older, older age, lower educational background and history of hypertension were associated independently with poor performance. Conclusion: These findings should be considered in planning specially tailored intervention for disability prevention in this subgroups. And this study provides the preliminary evidence that a SPPB is a useful tool in evaluating Korean elderly who are not disabled but have poor lower extremity performance.

슬관절 골관절염 환자와 정상인의 보행 시 슬관절 가속도
신준호(Joon-Ho Shin),김영진(Young-Gene Kim),홍대종(Dae-Jong Hong),나웅칠(oong-Chil Na),김영호(Young-Ho Kim),황선홍(Sun-Hong Hwang),김미정(Mi-Jung Kim),이규훈(Kyu-Hoon Lee),윤재남(Jae-Nam Yoon),박시복(Si-Bog Park) 대한임상노인의학회 2006 대한임상노인의학회지 Vol.7 No.2
목적: 보행 시 슬관절에는 내측으로 지면반발력이 작용하게 되어 외측으로 회전력이 발생하게 된다. 퇴행성 슬관절염은 이 회전력에 의해 슬관절 내측으로 가해지는 힘이 커져서 발생할 수 있는 것으로 알려져 있다. 이에 퇴행성 슬관절염 환자와 정상인의 슬관절 가속도를 측정하여 보행 시 슬관절에서 나타나는 가속도의 양상을 비교해보고자 하였다. 대상 및 방법: 정상 여성 22명과 퇴행성 슬관절염으로 진단 받은 성인 여성 22명을 대상으로 하였다. 같은 종류의 양말과 신발을 착용하여 편안한 걸음을 걷는 상태에서 무선가속도 측정시스템을 이용하여 슬관절의 가속도 변화를 측정하였다. 측정범위가±2 g (중력가속도)인 삼축 가속도 센서 CXL03LF3 (Crossbow, USA)를 비골두에 부착하여 가속도를 측정하였고 Mann-Whitney 검정법과 Spearman의 상관분석법을 이용하였다. 결과: 1) 퇴행성 슬관절염 환자에서는 정상인에 비해 부하 반응기 직후에 나타나는 슬관절 가속도의 첫 번째 최고치가 외측 방향과 앞쪽방향으로 크게 나타났다(p<0.01). 2) 퇴행성 슬관절염 환자에서는 정상인에 비해 편안한 걸음을 걷는 상태의 분속수가 유의하게 적었으나(p<0.01) 분속수와 슬관절 가속도의 상관관계는 없었다. 3) 퇴행성 슬관절염 환자와 정상인 모두에서 부하 반응기 직후에 나타나는 슬관절 가속도의 첫 번째 최고치가 외측 방향과 앞쪽 방향간에 유의한 상관관계를 보였으며(p<0.01) 전후측, 내외측, 상하측간에도 상관관계가 있었다(p<0.01). 결론: 퇴행성 슬관절염 환자에서는 보행시 정상인보다 부하 반응기 직후에 나타나는 슬관절 가속도의 최고치가 크게 나타났다. 이러한 결과로 보아 슬관절의 동적 가속도 형태를 관찰하는 것이 슬관절 질환 진단의 한 방법으로 사용될 수 있을 것으로 생각한다. Background: To investigate and describe the acceleration of the knee during walking in patients with osteoarthritis of knee and healthy adults. Methods: 22 patients with osteoarthritis of knee and 22 heathy adults participated in this study. The accelerometer fixed at left fibular head was used to record anterior-posterior, medio-lateral and superior-inferior accelerations of the knee during walking. Results: There was significant increase in lateral and anterior 1st peak of acceleration at loading response in the patients with osteoarthrits of knee compared to healthy adults (P<0.01). There was significant decrease in cadence in the patients with osteoarthritis of knee compared to heathy adults (P<0.01), but there was no significant correlation between cadence and 1st peak of acceleration at loading response. There was correlated with anterior and lateral acceleration in all subjects (P<0.01). Also there was relationship between anterior-posterior, medio-lateral and superior-inferior acceleration in all subjects (P<0.01). Conclusion: The accelerometer can be an easy and useful way to evaluate patients with osteoarthritis of knee.
