Light touch sensitivity of the foot sole is typically measured when individuals are seated or lying down; yet, a critical function of foot sole cutaneous feedback is to support standing and walking activities. The objective of this study was to evaluate the differences in how individuals perceive light touch stimulation across the foot sole when they are in different postures. To accomplish this, we measured the light touch perceptual threshold(LTPT) in standing, seated, and supine postures in 19 volunteers (9 males), using Semmes-Weinstein Monofilaments. Perceptual thresholds were calculated at three foot sole locations (1st metatarsal, lateral arch, and heel) …

Increased age and obesity diminish motivation, perseverance, and spatial memory function. Aerobic exercise interventions have successfully rescued some of these processes. However, in older and heavier populations aerobic exercise is not as sustainable due to high risk of injury. Resistance exercise consists of physical activity where maximum oxygen consumption is not increased and has been proposed as a safe and effective intervention for this population. Here, we used touchscreen-based cognitive testing to elucidate the influence of resistance exercise on motivation and spatial memory in aged, diet-induced obese mice, using a water restriction procedure I develop in Chapter 2. Mice underwent …
