Research: Sneaker Innovation & Technology on the Well-Being of Seniors

Mentor: Columbia SHAPE program


Within human anatomy, the structure of an overall foundation to the complexity of systems and processes are all carried externally by the feet. The feet are the body’s transportation and a vital component in the general survival of an individual. Maintaining the health of one’s feet can correspond to the all-inclusive health of one as well. In order to conserve this form, humans have manufactured the sneaker which allows the protection of the feet from any hazardous conditions or environment. Since the rapid increase of production in footwear from the rubbered toe sneaker at it’s dawn in 1892, the innovation and technology incorporated to the abilities of the product, in addition with the comprehension of scientific material such as structure and biomechanics, have produced significant changes to the lives of a spectrum of demographics. An innovation that has blossomed throughout the evolution is considered to be the unstable shoe with an elevated, rounded sole. Researchers have performed studies on the mechanism of the unstable shoe hypothesizing the shoe would result in a form of successful treatment to apply in clinical rehabilitation. Thus, the organization of an experiment in which participants wearing an unstable shoe would be attached to electrodes and enduring gait activity came to be. These electrodes would report electromyographic data on the rectus abdominis and erector spinae muscles as well as lumbar spine sagittal plane range of motion. This inspired the intended method of experiment to test the effect of the unstable sole ability on senior exercise in which the same experiment is conducted with increasing interval measurement to result in greater gait activity and a general subject qualification for elderly people. The results expected in this experiment should output a significantly higher muscle activity and strength in all phases of gait as well as for the increase in postural balance and muscular endurance. In the theme of support, it is expected for a higher support in trunk muscles and aerobic control. As the final analysis, the unstable shoe is predicted to have an impact of clinical rehabilitation as a method of strengthening lower extremity muscles, LBP Treatment, and physical therapy for the reversal of lordosis, but also, be a form of confidence and motivation to extreme improvement in physical activity for seniors
