BIOMCH-L Listserv Members,

I am studying the kinematic and kinetic changes associated with mild head injury. One of my hypotheses suggests that subjects with mild head injury will experience a greater instability that match subjects without. I am also hypothesizing that subjects with mild head injury are more likely to experience a "hip" strategy as opposed to an "ankle" strategy. Although I have found a number of references that discuss the differences between the two, I have not come across a reference that identifies the key variable of measure to differentiate between the two strategies.

I would think that relative range of motion (ROM subject's hip/ankle went through with respect to their total ROM) would be a better indicator than simply comparing variation of joint angles at the hip and ankle. A variation of 10deg at the hip would be a lot less significant than the same variation in the ankle.

Does anyone have any information that they would like to provide me? I will post a summary of the findings to the listserv if there is interest.

Thank you for your time,
