Overview
Brief Summary
This is a short term study of the effects of bariatric surgery on body composition, gait parameters during walking, lower extremity joint pain and quality of life (QOL) in morbidly obese patients who are already scheduled for a bariatric surgical procedure.
Detailed Description
This is a prospective, exploratory, short term study of the effects of bariatric surgery on body composition, gait parameters during walking, lower extremity joint pain and quality of life (QOL) in morbidly obese patients. All patients who enroll have already agreed to undergo the bariatric procedure with their respective surgeon; the study team will simply follow specific outcome measures in addition to their normal clinical care at two time points after the surgery (week 4 and month 3).

Outcomes
Primary Outcomes
Body Composition, describes change in body composition from pre-op levels
Time Frame: Describes change over a period of 4 weeks; measured at pre-op, 2 and 4 weeks following surgery
To track changes in body composition and mass during the study, body weight body fat mass, fat free mass will be collected prior to and 2 and 4 weeks after the bariatric surgery using air plethysmography. Air plethysmography (using the BOD POD®) is a reliable technique of body volume and composition, and has been validated for use in obese individuals and is highly correlated to the gold standard of body composition assessment, underwater weighing.
Secondary Outcomes
- Gait Analysis, describes change in gait parameters from pre-op levels(Describes changes in gait parameters over a 3 month period; measured at pre-op, 4 weeks and 3 months following surgery.)
- Lower Extremity Joint Pain, describes change from pre-op using a Visual Analog Scale (VAS).(Describes change in lower extremity joint pain over a period of 3 months; measured with a (VAS) at per-op, 4 weeks and 3 months following surgery)
- Medical Outcomes Short Form (SF-36), describes change in perceived quality of life (QOL)(Describes perceived (QOL) over a period of 3 months, measured at pre-op, 4 weeks and 3 months following surgery)
