Recent Funding
- NIH - Centers of Biomedical Research Excellence (Todd Royer, PI for project #3; Irene Davis, co-PI), $931,815; "Effect of In-Shoe Orthoses on Lower-Extremity Function in Patients with Knee Osteoarthritis"; (2002-07) P20 RR16458 (Tom Buchanan PI for the COBRE center grant)
Current Research
- We are currently investigating 1) secondary disability of lower-extremity amputation (e.g., gait asymmetry, increased metabolic cost of locomotion, increased risk of joint degradation) and 2) a conservative in-shoe wedged orthotic treatment for knee osteoarthritis.
