- History of prior ankle surgery
- History of ankle or foot fracture
- Diabetes mellitus
- Current self-reported disability due to lower extremity pathology that may adversely affect neuromuscular function

Arms of the Study
Arm 1
Arm 2
Experimental
Experimental
Intrinsic Foot Arm
Joint Mobilization Arm
In arm 1, a randomized control trial will be used in the investigation of validity and reliability comparing multisegmented foot motion, clinical joint physiological and accessory motion, and morphologic foot measurements, and the effect of intrinsic foot strengthening on multisegmented foot function.
In arm 2, the investigation of group differences in clinical and laboratory measures of multisegmented foot motion and kinetics will use a case control design. A randomized controlled trial will be conducted in the study investigating joint mobilization, with the researcher performing the assessments and the provider performing the treatments blinded to group allocation
