Relationship between Physical Functions and Preoperative Physical Activity in Patients with Peripheral Arterial Disease Undergoing Endovascular Treatment / The Japanese Journal of Rehabilitation Medicine

Objective：To investigate the physical functions of peripheral arterial disease (PAD) patients undergoing endovascular treatment (EVT), and their association with physical activity before EVT.Methods：One hundred and one PAD patients underwent EVT. Physical functions were specified as grip strength, walking speed, and the weight ratio of knee extension isometric muscle strength (KEIS). We divided the patients into 3 groups, based on the amount of physical activity per week：(a) low activity (0 kcal/week：n＝52), (b) moderate activity (0 kcal to less than 500 kcal/week：n＝22), and (c) high activity (more than 500 kcal/week：n＝27). Physical activity data were collected using an international standardized physical activity questionnaire. A multivariate regression analysis (cumulative logit model) was used to evaluate the association between physical activity (low activity, moderate activity, high activity) and KEIS＜0.4 kgf/kg.Results：The averages of the physical functions were：grip strength (kg；Men 28.1, Women 16.6), walking speed (m/s；Men 1.10, Women 0.96), KEIS (kgf/kg；Men 0.42, Women 0.28). The prevalence of KEIS＜0.4 kgf/kg was 56.4％ (n＝57). KEIS＜0.4 kgf/kg was not significantly different between low and moderate activity groups (Odds：0.99, p＝0.98). However, KEIS＜0.4 kgf/kg was significantly different between low and high activity groups (Odds：5.02, p＝0.007).Conclusion：Physical functions were lower in PAD patients undergoing EVT than in healthy adults of the same age, and KEIS was related to physical activity before EVT.
