ABSTRACT The present study examined the effects of a regular walking exercise program on behavioral (daily physical activity, physical strength, energy consumption) and biochemical (fasting blood glucose [FBG], glycated hemoglobin [HbA1c], total cholesterol, triglycerides [TG], low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol) aspects of elderly people with type II diabetes. A randomized and stratified experimental design was used with experimental and control groups. The experimental group was subjected to a 6 month walking exercise program, involving walking exercise three times per week for 50 min, and a 4 week education program on diet control and the prevention of complications, once per week for 20 min. Post-test was conducted after 3 and 6 months to examine short- and long-term behavioral and biochemical effects. The regular walking exercise program effectively increased daily physical activity, physical strength, and energy consumption (behavioral aspects), and decreased FBG, HbA1c, and TG levels (biochemical aspects) in elderly people with type II diabetes. The incidence of type II diabetes complications might be reduced by implementing a regular walking exercise program.

    ABSTRACT: Distal symmetric polyneuropathy increases fall risk due to inability to cope with perturbations. We aimed to 1) identify the frontal plane lower limb sensorimotor functions which are necessary for robustness to a discrete, underfoot perturbation during gait; and 2) determine whether changes in the post-perturbed step parameters could distinguish between fallers and non fallers. Forty-two subjects (16 healthy old and 26 with diabetic PN) participated. Frontal plane lower limb sensorimotor functions were determined using established laboratory-based techniques. The subjects' most extreme alterations in step width or step length in response to a perturbation were measured. In addition, falls and fall-related injuries were prospectively recorded. Ankle proprioceptive threshold (APrT; p=.025) and hip abduction rate of torque generation (RTG; p=.041) independently predicted extreme step length after medial perturbation, with precise APrT and greater hip RTG allowing maintenance of step length. Injured subjects demonstrated greater extreme step length changes after medial perturbation than non-injured subjects (percent change = 18.5 ± 9.2 vs. 11.3 ± 4.57; p = .01). The ability to rapidly generate frontal plane hip strength and/or precisely perceive motion at the ankle is needed to maintain a normal step length after perturbation, a parameter which distinguishes between subjects sustaining a fall-related injury and those who did not.
