One of the main indicators of the suspension system efficiency in
lower limb prostheses is vertical displacement or pistoning within the socket.
Decreasing pistoning and introducing an effective system for evaluating pistoning
could contribute to the amputees' rehabilitation process. The main
objective of this study was to review existing research studies that examine the
occurrence of pistoning in lower limb prosthesis with different techniques in
static (standing) and dynamic (walking and jumping) positions. STUDY DESIGN:
Literature review. METHODS: Keywords related to slippage, suspension, pistoning
and vertical movement in lower limb prosthetics were used to search the
literature available in PubMed, ScienceDirect, Web of Science and Google Scholar
databases. Sixteen articles were selected for further analysis according to the
selection criteria. RESULTS: The following methods have been used to measure the
occurrence of pistoning in prosthetic limbs: radiological methods, photographic
technique, motion analysis system, sensor and spiral computerized tomography
(CT). Pistoning was measured both in standing and walking. CONCLUSIONS: The
results of this review reveal that further research is needed to develop and
evaluate easy, accurate and safe methods of measuring pistoning. Future studies
should provide a gold standard for the acceptable range of pistoning in a
prosthetic socket.
