This study aimed to assess whether a 4% compression value in 3- and 5-mm thickness affordable ethylene-vinyl acetate roll-on (AERO) liners yields acceptable comfort and pressure distribution for transtibial prosthetic users. Stump socks were used to adjust volume in the fitting process with a socket compressed to 4%, and pressure data were collected using 6 force-sensing resistor (FSR400) sensors placed in areas sensitive and tolerant to pressure. Peak pressure was collected from 40 steps, and pressure uniformity was calculated using the coefficient of variation in 2-min walking on the treadmill. The socket comfort score was collected after the trial. Appropriate compression values, pressure distribution, and socket comfort score were analyzed using Wilcoxon signed-rank tests, and effect size was determined using Cliff's delta. The study found that a 4.95% compression was optimal for a 3-mm thickness liner, whereas a 4.5% compression suited a 5-mm liner better for comfort. Moreover, the study observed a small similarity in pressure distribution between liners, as indicated by Cliff's delta, with the 5-mm liner possibly providing more even pressure because of its thickness. Despite being made of the same material, liners with different thicknesses distribute pressure differently. Therefore, this study suggests that a 4% universal compression value in the affordable ethylene-vinyl acetate roll-on liner may be effective for use in a clinical setting. Future studies should include more participants to identify the appropriate compression for a variety of residual limbs.</p>","PeriodicalId":49657,"journal":{"name":"Prosthetics and Orthotics International","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143812771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The custom insert (termed \"inlay\") relies on a triangular unit cell, which can be modified based on the desired stiffness profile. Inserts are 3D printed in a soft polymer material and inset into shape-matched voids in a socket creating regions of custom offloading.

Peak pressures within the distal tibial region of interest were decreased for 2 of 3 participants during midstance of level-ground walking when wearing the socket with inlays.

Between October and December of 2021, 2 participants with unilateral traumatic Gritti-Stokes amputation, who had received seal-in suction suspension for their preparatory prostheses, were recruited.

At definitive prosthesis evaluations, both participants were unlimited community ambulators; both successfully returned to work before provision of their definitive prostheses.
