“…54 Six papers were case studies. 31,[33][34][35][36]55 Time since amputation was between one month 56 and 46 years 34 ; however, not all studies provided details of the time since amputation. While both unilateral and bilateral amputees were included, the subjects were mostly unilateral transtibial amputees.…”

“…32 Recently, a simple photographic method has been reported 29,36-37 and finally, Gholizadeh et al 38 used Vicon motion analysis system to evaluate pistoning in transtibial amputees. The literature review revealed that the majority of researchers measured the displacement between the bone and the socket, the liner and socket or the soft tissue, by using different techniques in static position 19,29,32,[34][35][36][37][38]53,55 or during dynamic tasks 33,35,54,[60][61] to check pistoning inside the socket. Therefore, the methods available were classified according to whether they utilized static or dynamic pistoning.…”

Background: 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.Objectives: 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.Clinical relevanceThis literature review contributes to a further understanding of lower limb prosthetic biomechanics by highlighting the strengths and weaknesses of the techniques that are currently available for evaluating the occurrence of pistoning in a prosthetic socket. It provides a useful overview of the current methods of measuring residual limb movements relative to the socket and liner, and will be of use for both practitioners and researchers in prosthetics and orthotics fields.

“…The most frequent design was a crossover design (n = 9) [27][28][30][31][32][33][41][42][43], followed by five single-subject/case studies [34][35][38][39]44], four randomized crossover trials [13][14]21,29], and three case series [26,[46][47]. The remaining studies were repeated-measure design (n = 1) [45], randomized controlled trials (n = 2) [22,24], cross-sectional design (n = 2) [36][37], and prospective study (n = 1) [40] Table 1.…”

Moderate evidence-Based on a case series by Hachisuka et al (DBS 23), pistoning, tightness of socket during walking, and ease of swing were regarded as "good" or "somewhat good" for TSB sockets with laminated silicone liners by more than 75 percent of participants [49].…”

Abstract-This review is an attempt to untangle the complexity of transtibial prosthetic socket fit and perhaps find some indication of whether a particular prosthetic socket type might be best for a given situation. In addition, we identified knowledge gaps, thus providing direction for possible future research. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, using medical subject headings and standard key words to search for articles in relevant databases. No restrictions were made on study design and type of outcome measure used. From the obtained search results (n = 1,863), 35 articles were included. The relevant data were entered into a predefined data form that included the Downs and Black risk of bias assessment checklist. This article presents the results from the systematic review of the quantitative outcomes (n = 27 articles). Trends indicate that vacuum-assisted suction sockets improve gait symmetry, volume control, and residual limb health more than other socket designs. Hydrostatic sockets seem to create less inconsistent socket fittings, reducing a problem that greatly influences outcome measures. Knowledge gaps exist in the understanding of clinically meaningful changes in socket fit and its effect on biomechanical outcomes. Further, safe and comfortable pressure thresholds under various conditions should be determined through a systematic approach.

The relationship between residual limb health, motion within the socket, and prosthetic suspension

Residual limb health is critical for continued prosthesis use; however, many prosthesis users experience skin‐related breakdown. The interface between the residual limb and the prosthetic socket sets the local mechanical environment and plays a role in skin stresses. Motion of the residual limb in the socket adds additional mechanical strain on the limb. This article explores the relationship between motion of the limb in the socket and residual limb health. We evaluated current methods for assessing residual limb health and motion of the residual limb in the socket and compared these evaluations across different prosthetic suspension systems. While few direct studies comparing residual limb health and motion exist, it has been shown that elevated vacuum suspension systems result in both improved residual limb health compared to passive suction and pin‐lock systems and decreased motion compared to passive suction, pin‐lock, knee sleeve, and anatomical suspension systems. While motion and health have not been directly linked, elevated vacuum suspension may demonstrate a relationship that reduced motion of the residual limb in the socket improves residual limb health. Further evaluation in this area is necessary to more completely and directly understand the relationship between residual limb motion and residual limb health.
