[Participants and Methods] This was a retrospective study. We included 50 patients (61 limbs; 38 males and 12 females; mean age, 73 years) who underwent lower-extremity bypass surgery for Fontaine stage 2-3 PAD. The patients were assigned to the aortoiliac (A-I) group (n=23), femoropopliteal (F-P) group (n=18), and below-knee group (n=9). We evaluated the postoperative rehabilitation progress and length of hospital stay of these groups. [Results] The postoperative ankle-brachial pressure index (ABI) of the A-I group was significantly lower than that of the F-P group, although there were no differences before surgery. The progress of rehabilitation and the length of hospitalization showed no significant differences among the three groups. The postoperative date of independent walking was significantly later in the presence of complications than in the absence of complications. [Conclusion] The progress of rehabilitation after lower-extremity bypass surgery did not differ depending on the occlusive lesions, and patients may acquire independent walking ability in approximately 5 days in the absence of postoperative complications.[Purpose] To examine the effects of age and gender in an ageing population with respect to functional decline and the relationship between muscle power and functional capacity. [Participants and Methods] The cohort (N=154) was subdivided into youngest-old (65-70 years.; n=62), middle-old (71-75 years.; n=46), and oldest-old (76-81 years.; n=46). Measures of mechanical muscle function included countermovement jump height, muscle power, leg strength and grip strength. Functional performance-based measures incl
