Muscle Nerve 45:849-58. 2012..g., after a stroke). Presently, there is no agreed-upon practical method for calculating the MFGA in individuals with central nervous system pathology. The purpose of this study was to identify the best method for determining MFGA...
- The relative contribution of ankle moment and trailing limb angle to propulsive force during gaitHaoYuan Hsiao
Biomechanics and Movement Science Program, University of Delaware, 547 S College Avenue, Newark, DE 19716, United States Electronic address
