Performance-based balance tests, combined with the number of falls recalled in the past year, predicts the incidence of future falls in established unilateral transtibial prosthesis users.

PM R 2021 May 5. Epub 2021 May 5.

Department of Rehabilitation Medicine, University of Washington, Seattle, WA, 98195.

Introduction: Falls are common and consequential events for lower limb prosthesis (LLP) users. Currently, there are no models based on prospective falls data that clinicians can use to predict the incidence of future falls in LLP users. Assessing who is at risk for falls, and thus most likely to need and benefit from intervention, remains a challenge. Read More

Curr Phys Med Rehabil Rep 2020 Sep 3;8(3):92-109. Epub 2020 Aug 3.

Delaware Limb Loss Studies, Department of Physical Therapy, University of Delaware, Newark, Delaware, USA.

Purpose Of Review: To summarize outcome measurement research among adults with lower-limb loss (LLL) for clinicians.

Recent Findings: Houghton Scale, Prosthetic Evaluation Questionnaire-mobility subscale (PEQ-m), Prosthetic Limb Users Survey of Mobility (PLUS-M™), Activities-Specific Balance Confidence Scale (ABC), Amputee Mobility Predictor (AMP), Comprehensive High-Level Activity Mobility Predictor, Four Square Step Test (FSST), Narrowing Beam Walking Test (NBWT), L Test, 10 Meter Walk Test (10MWT), and 6 Minute Walk Test (6MWT) are appropriate for evaluating individual patient changes post-LLL. Post-LLL, Socket Comfort Score, Patient-Specific Functional Scale, Patient-Reported Outcomes Measurement Information System 29-Item Profile, Timed Up and Go, and 2 Minute Walk Test may be more appropriate for evaluating groups.

The influence of powered prostheses on user perspectives, metabolics, and activity: a randomized crossover trial.

J Neuroeng Rehabil 2021 03 16;18(1):49. Epub 2021 Mar 16.

School of Kinesiology, University of Michigan, 401 Washtenaw Avenue, Ann Arbor, MI, 48109-2214, USA.

Background: Powered prosthetic ankles provide battery-powered mechanical push-off, with the aim of reducing the metabolic demands of walking for people with transtibial amputations. The efficacy of powered ankles has been shown in active, high functioning individuals with transtibial amputation, but is less clear in other populations. Additionally, it is unclear how use of a powered prosthesis influences everyday physical activity and mobility. Read More

Should weight-bearing activity be reduced during healing of plantar diabetic foot ulcers, even when using appropriate offloading devices?

Diabetes Res Clin Pract 2021 Mar 10;175:108733. Epub 2021 Mar 10.

Program in Physical Therapy and Department of Radiology, Washington University School of Medicine in St Louis, St. Louis, MO 63108, USA. Electronic address:

Physical activity is an essential part of general health and diabetes management. However, recommending weight-bearing physical activity for people with plantar diabetic foot ulcers is controversial, even when gold standard offloading devices are used, as it is commonly thought to delay healing. We aimed to narratively review relevant studies investigating the relationship between plantar diabetic foot ulcer healing and weight-bearing activity, plantar pressure and device adherence.

Effects of Handrail and Cane Support on Energy Cost of Walking in People With Different Levels and Causes of Lower Limb Amputation.

Arch Phys Med Rehabil 2021 Mar 5. Epub 2021 Mar 5.

Amsterdam Movement Science, Faculty of Behavioral and Movement Sciences, Vrije Universiteit Amsterdam, Amsterdam, The Netherlands.

Objective: The energy cost of walking with a lower limb prosthesis is higher than able-bodied walking and depends on both cause and level of amputation. This increase might partly be related to problems with balance control. In this study we investigated to what extent energy cost can be reduced by providing support through a handrail or cane and how this depends on level and cause of amputation. Read More

Material properties and application of biomechanical principles provide significant motion control performance in experimental ankle foot orthosis-footwear combination.

Clin Biomech (Bristol, Avon) 2021 02 30;82:105285. Epub 2021 Jan 30.

School of Integrated Health Sciences, University of Nevada Las Vegas, Las Vegas, NV 89154, USA.

Background: This study, the first of its kind, originated with the need for a brace (an ankle foot orthosis), to constrain ankle plantarflexion and dorsiflexion within a motion threshold of <5°. A conventional thermoplastic, solid brace failed during a quasi-static loading study, informing the investigation and development of an experimental carbon composite brace, maximizing stiffness and proximity of shank and foot cylindrical shells to provide the required degree of control.

Methods: Two experiments were conducted: a quasi-static loading study, using cadaveric limbs (n = 2), and a gait study with healthy subjects (n = 14). Read More

A Biomimetic Adapter for Passive Self-alignment of Prosthetic Feet.

Mil Med 2021 01;186(Suppl 1):665-673

Ability Prosthetics & Orthotics, Mechanicsburg, PA 17050, USA.

Introduction: Dynamic alignment of lower limb prostheses is subjective and time-consuming. Compensatory gait strategies caused by prosthesis misalignment can negatively affect lower limb amputees who cannot access a certified prosthetist for alignment adjustments. The objective of this study is to evaluate a novel six-degrees-of-freedom passive transtibial prosthetic adapter that self-aligns during various phases of gait. Read More

Wireless sensors for continuous, multimodal measurements at the skin interface with lower limb prostheses.

Sci Transl Med 2020 12;12(574)

Querrey Simpson Institute for Bioelectronics, Northwestern University, Chicago, IL 60611, USA.

Precise form-fitting of prosthetic sockets is important for the comfort and well-being of persons with limb amputations. Capabilities for continuous monitoring of pressure and temperature at the skin-prosthesis interface can be valuable in the fitting process and in monitoring for the development of dangerous regions of increased pressure and temperature as limb volume changes during daily activities. Conventional pressure transducers and temperature sensors cannot provide comfortable, irritation-free measurements because of their relatively rigid construction and requirements for wired interfaces to external data acquisition hardware.

[The necessity for treatment paths for lower limb prosthetics : All that glitters is not gold!]

Orthopade 2021 Jan;50(1):44-50

PohligGmbH, Waldhoferstraße 98, 69123, Heidelberg, Deutschland.

Background: Frequently occurring problems in the fitting of leg prostheses are either, for a prosthetic fitting, insufficiently resilient leg stumps or insufficiently adapted prostheses. For this reason, there has been a demand at the political level to establish treatment pathways and a quality standard for the care of people after leg amputations.

Question: How can a joint, interdisciplinary approach to the provision of aids be developed? Does interdisciplinary care of amputees lead to an improvement in the quality of care?

Material And Method: A compendium "Quality standard in the field of lower extremity prostheses" was compiled and presented at the OT World in Leipzig in 2018. Read More
