Therefore, the aim of this scoping review was to provide a state-of-the-space review of the studies that investigate AFO ankle stiffness in the sagittal plane and then provide insight into the details of the developed devices and protocols. Six electronic databases (MEDLINE, SCOPUS, Web of Science, CINAHL, EMBASE, and IEEE Xplore) were searched for studies from when indexing began to April 2024. Articles of any design that developed or used testing devices and/or protocols to assess AFO ankle stiffness in the sagittal plane were eligible. Seventy-two articles were included in this review, of which 51 developed mechanical testing devices/protocols to quantify AFO stiffness while 21 articles referenced existing methods. The most common apparatuses used in the primary studies were the universal testing machine and customized manual machines. Other methods included specialty automated devices, manual devices in a gait analysis laboratory, hanging weights, universal testing machine combined with motion capture, muscle training machine, and 6-axis robot arm. Ankle angle of the AFO was the most common controlled variable, followed by loading force. This scoping review comprehensively outlines the variety of devices and protocols used to assess AFO ankle stiffness in the sagittal plane. Many researchers chose methods that leveraged their available resources, demonstrating a variety of approaches. For future studies, we recommend that parameters chosen are justified, reliability studies are undertaken, and AFO design is adequately reported.","PeriodicalId":49657,"journal":{"name":"Prosthetics and Orthotics International","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144856899","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}

However, fluctuations in shear (parallel) forces on the buttocks during postural changes may cause discomfort, yet this relationship is not well understood.Objectives: To examine how combined use of tilt-in-space and reclining functions affects fluctuations in parallel forces on the buttocks, and how these fluctuations relate to subjective discomfort.Study design: Cross-sectional experimental study.Methods: Nineteen healthy adult males (mean age: 27.7 ± 10.3 years) participated. An experimental ergonomic chair was used under 2 conditions: 1 with a seat-cover assembly that conforms to the back shape, and a control condition with a flat back-support. Participants experienced a 10 degrees tilt-in-space and reclining angles from 100 degrees to 130 degrees. Fluctuations in parallel forces on the buttocks were measured using a force plate, and subjective discomfort was assessed with a visual analog scale. Stepwise multiple regression was used to analyze associations between force fluctuation and discomfort.Results: The seat-cover assembly condition resulted in significantly lower visual analog scale scores (median: 4, interquartile range: 0-13) compared to the control (median: 46, interquartile range: 24-72; p < 0.01). Regression analysis revealed that only the fluctuation in parallel forces significantly predicted discomfort (β = 0.722, R² = 0.507, p < 0.01).Conclusions: Fluctuations in parallel forces during tilt and recline use are significantly associated with discomfort.

A single active transtibial amputee (27 male) was fitted with a new prosthetic socket and attended weekly data capture sessions using their prosthesis normally.Results: Here, we present evidence for alteration in prosthesis-residuum coupling performance, notably, the average proximal/distal displacement (pistoning) increased from 3.36 to 10.60 mm at week 6 from the first fit, which further increased to 12.90 mm with the use of a single prosthetic sock.

Risk factors for falls in people with a lower limb amputation: a systematic review. Amer Acad of Phys Med and Rehabil. 2017; 9(2):170-180). Limited studies have investigated muscle power output for individuals with lower-limb loss and high fall risk. This study aims to examine the effects of contraction speed on lower-extremity muscle power among 3 groups: control, nonfaller, and fallers with lower-limb loss.Methods: Thirteen adults without lower-limb loss and 15 adults with lower-limb loss were recruited. Bilateral average power for hip, knee, and ankle was evaluated at 60°/s and 120°/s using a Biodex™ dynamometer. A mixed-model ANOVA was used to identify group and speed effects on muscle power.Results: Sound limb hip extensor and flexor muscle power were significantly weaker in fallers compared with nonfallers (P = 0.048 and P = 0.43, respectively). Fallers were significantly weaker than control in sound limb hip extensor/flexor and affected knee extensor/flexor muscle groups, while nonfallers' sound hip muscle power was similar to the control. Significant speed effects were found in most muscle power values for control and nonfallers but only found in fallers' sound knee extensors.Conclusions: Sound hip muscle weakness may contribute to a higher fall risk for individuals with lower-limb loss. Control and nonfallers with limb loss actively adjusted their muscle power output during higher velocity contractions, while fallers with limb loss could not adapt. Incorporating high-velocity power training may reduce fall risk in individuals with lower-limb loss.","PeriodicalId":49657,"journal":{"name":"Prosthetics and Orthotics International","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144638496","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}

Little is known about the ability to rise from the floor among persons with a transtibial amputation (TTA).Objectives: The objectives of this pilot study were to (1) identify movement strategies and performance time demonstrated when rising from the floor among persons with a transtibial prosthesis and (2) examine concurrent validity of the timed supine to stand test (TSST).Study design: The study used a cross-sectional design.Methods: Eleven participants (9 male; mean age 58.7 [SD 12.7] years) with a unilateral TTA participated. Participants completed a TSST and were observed for common motor strategies, including chair use and half-kneel transitions. Additional outcomes included the Activities-specific Balance Confidence Scale (ABC), Timed Up and Go Test, and Short Physical Performance Battery.Results: The mean time to rise from the floor was 10.6 (5.6) s. There was a significant association between TSST performance and age (r = 0.67; P = .03), the ABC (r = -0.72; P = .01), and performance on the Timed Up and Go (r = 0.64; P = .04) and Short Physical Performance Battery (rho = -0.67; P = .007). Six participants (54.5%) required the use of external support (chair) to stand, and 6 (54.5%) initially led with the prosthetic limb to achieve half-kneeling with the prosthetic foot on the surface.Discussion: Findings support that the TSST is related to physical performance, age, and ABC among persons with a TTA.
