The purpose of this study is to examine muscle a ctivity using EMG during treadmill wa lking wea ring a rocker bottom shoe. Recent literature sea rches have examined the use of rocker bottom shoes specifically examining pathologies such as RA, diabetes, pressure distribution and specific a natomical locations of the foot during gait (25). In addition, there has been research investigating the biomecha nical effects of using a rocker bottom shoe with a mbulation (18). In recent yea rs the shoe compa ny Sketchers has presented claims that their "Shape-up" shoes (featuring a rocker bottom sole) a re efficacious in "improving posture, reducing back stress, firming musculature of the buttocks, toning and firming thigh and calf muscles. The benefits of Shape-ups as claimed by Sketchers include efficient work out: wearing Shape-ups foot wear may result in more toned leg and buttock muscles. Higher Ca lorie burn: studies have shown that wea ring curved-bottom shoes like Sha pe-ups regula rly may help burn ca lories. Lower impact on joints: Sha pe-ups are designed to simulate a more natural walking surface a nd have superior cushioning to help a bsorb some of the impact on your joints. Improve posture: Sha pe-ups help train your body to stand stra ighter a nd taller as you walk"(26). The above claims were made by Skechers via the company website (www.Sketchers.com) prior to May of 2012. The cla ims have since been a ltered based on a lawsuit that the company misrepresented the benefits of wearing the rocker soled shoe. As physical therapy students, we wanted to know if the benefits of the claims made by Sketchers would be adva ntageous to increase muscle activity during ambulation for our patients. The purpose of our study is to use EMG to determine whether or not the claims made by the shoe compa ny a re in fact true. It is our hypothesis that the use of Shape-up shoes will not increase muscle activity of the lower extremities in subjects vs. the use of self\xad selected athletic shoes.
