A prosthetic leg should be securely attached to the limb so that the user feels it as part of his or her own body. Different methods have been used to evaluate the pistoning movement of the residual limb inside the socket. The majority of existing research is based on pistoning measurement in quiet standing rather than walking. We introduce a new technique for evaluating prosthetic suspension during walking using a motion analysis system. This study revealed that other factors such as donning and doffing might be more clinically significant in a person with amputation’s satisfaction than pistoning once a reasonable level of pistoning is reached.
