BACKGROUND: Medial meniscus extrusion (MME) is associated with knee osteoarthritis (OA) progression because of increased loading stress in the medial compartment of the knee. Using a lateral wedge insole (LWI) decreases loading stress and immediately reduces MME. OBJECTIVE: To investigate whether the wearing duration of LWI affects the midterm response to MME and is associated with knee OA progression. STUDY DESIGN: Cohort study. METHODS: Twenty-three patients with knee OA who were conservatively treated with LWI were classified according to the duration of the LWI wear per day: less than 5 h (short-duration group) or over 5 h (long-duration group)...

BACKGROUND: After lower limb amputations, a decrease in gait capacity, even with prostheses, is common and persistent. Functional ability involves multiple constructs; therefore, several outcome measures, such as performance tests or self-report questionnaires, should be used to evaluate people with amputation who use prostheses. OBJECTIVE: To analyze the convergent construct validity of the Brazilian version of the Houghton scale in a sample of lower limb prosthesis users...

BACKGROUND: Nonsurgical guidelines recommend implementing a correctly fitted bra when managing back pain among larger breasted women. Achieving this is challenging with current bra solutions, sizing principles, and fitting approaches. Persistent wearing of an ill-fitting bra can cause negative health implications, including non-specific back pain. OBJECTIVES: This study investigated immediate and short-term biomechanical and pain responses to changing breast support garment among larger breasted women with non-specific back pain...

BACKGROUND: Although postoperative complications of lower limb amputations and complications related to prosthetics are well known, complications before prosthetic fitting are less often emphasized in literature. There are no Saudi studies documenting the complications before prosthetic fitting where there is high rise in dysvascular amputation, and early prosthetic provision remains a challenge. OBJECTIVES: To investigate the complications following major lower limb amputations (MLLAs)...

BACKGROUND: An undergraduate research project gives prosthetic and orthotic (P&O) students the chance to acquire both foundational research knowledge and in-depth knowledge in a specific area of interest in P&O research. Undergraduates frequently enter the field of research with less experience or understanding of research instruments, presenting them with significant obstacles when conducting research. OBJECTIVE: This study's objective was to establish a framework for undergraduate research training in prosthetics and orthotics education...

BACKGROUND: Returning to work is a key outcome of rehabilitation and social re-integration after lower limb amputation. It is important to understand what biopsychosocial factors contribute to returning to work after dysvascular amputation. OBJECTIVE: Examining relative contributions of functional and contextual predictors of returning to work in participants with lower limb amputation due to diabetes and other dysvascular diseases. STUDY DESIGN: Cross-sectional...

BACKGROUND: Ankle-foot orthoses (AFOs) are a type of assistive device that can improve the walking ability of individuals with neurological disorders. Adjusting stiffness is a common way to customize settings according to individuals' impairment. OBJECTIVE: This study aims to design a variable-stiffness AFO by stiffness module and characterize the AFO stiffness range to provide subject-specific settings for the users. METHODS: We modeled AFO using bending beams with varying fulcrum positions to adjust the stiffness...

This systematic review aims to assess and summarize the current landscape in exoskeletons and orthotic solutions developed for upper limb medical assistance, which are partly or fully produced using 3-dimensional printing technologies and contain at least the elbow or the shoulder joints. The initial search was conducted on Web of Science, PubMed, and IEEEXplore, resulting in 92 papers, which were reduced to 72 after removal of duplicates. From the application of the inclusion and exclusion criteria and selection questionnaire, 33 papers were included in the review, being divided according to the analyzed joints...

OBJECTIVES: Individuals with lower-limb amputations (LLA) often have deficits in balance and community walking ability. As a result, people with LLA are often sedentary. The aim of this study was to explore perceptions of physical activity from the perspective of people with LLA.
