Background Foot orthoses are among the most commonly used external supports to treat musculoskeletal disorders. It remains unclear how they change the biomechanics of the lower extremities during functional tasks. This systematic review aimed to determine the effects of foot orthoses on primary outcomes (i.e., kinematics, kinetics and electromyogra...

Background Foot orthoses (FOs) are commonly prescribed devices to attenuate biomechanical deficits and improve physical function in patients with musculoskeletal disorders. It is postulated that FOs provide their effects through the production of reaction forces at the foot-FOs interface. An important parameter to provide these reaction forces is t...

Introduction Foot orthoses are therapeutic insoles designed to induce various effects on lower limb biomechanics [1]. They aim to treat foot and ankle disorders and prevent lower limb disorders [2-4]. However, there are conflicting findings in previous studies concerning their biomechanical effects [5]. This highlights the need to better understand...

Background Supination resistance is a clinical outcome that estimates the amount of external force required to supinate the foot. A greater supination resistance may indicate greater loads on structures responsible for generating internal supination moments across the subtalar joint during static and dynamic tasks. As such, greater supination resis...

Aims: Diabetic peripheral neuropathy (DPN) is a predictor of foot ulcers and leads to sedentary behaviour. This comparative study evaluated gait and feasibility of a 20-minute fast walk, at 40-60% of cardiopulmonary capacity, in individuals with DPN wearing an offloading boot and a contralateral shoe balancer. Methods: Gait parameters were measu...
Article
Background Individuals with a lower limb amputation use compensatory strategies during essential tasks such as sit-to-stand and stair ascent leading to secondary physical conditions. The ensuing biomechanical parameters outlining the motion strategies they put in place need to be identified and described. Methods We searched three databases (Embas...

Purpose The biomechanical impact of undergoing a single-event multilevel surgery (SEMLS) for children with cerebral palsy (CP) presenting an intoeing gait pattern has been widely documented. However, past studies mostly focused on gait quality rather than efficiency. Thus, there is a need to determine the impact of undergoing a SEMLS on gait qualit...

Background: The first metatarsophalangeal joint plays a fundamental role during the gait cycle. The Hubscher manoeuvre, which consists of passively dorsiflexing the first metatarsophalangeal joint of an individual in relaxed stance and observing the raising of the medial longitudinal arch, is a clinical test thought to examine the function of the...

Article
Background The supination resistance test (SRT) is a kinetic test used in clinical and research contexts to estimate the amount of force required to supinate the foot. Previous studies either used a manual, less reliable version of this test or a more reliable instrumented version, but with devices inconvenient for clinical use. The clinically avai...

Background: Many individuals with a transtibial amputation (TTA) exhibit balance deficits after limb loss. However, limited evidence exists on balance deficits of individuals with a TTA using hip, knee, and ankle kinematics and center of mass outcomes. Objectives: To identify balance control deficits in individuals with a TTA and determine to wh...

Background: Postural control impairments following a stroke have an impact on mobility, reduce independence, and increase the risk of falls. Assessing these impairments during tasks representative of real-life situations, such as quiet standing (QS) and voluntary stepping response (VSR), will enhance our understanding of how the postural control sy...

Article
Background: Most previous studies reported biomechanical deficits in individuals with a trans-tibial amputation (TTA) during gait using zero-dimensional analyses. However, these analyses do not allow to precisely determine during which part of the gait cycle these deficits occur. There is a need to use more appropriate methods to map the differenc...

Introduction In clinical practice, different types of rearfoot and forefoot extrinsic posts are regularly added to foot orthoses (FOs) to make the treatment more specific. However, to this day, their effects on muscle activity during walking are still unclear and few studies have quantified them. The purpose of this case study was to quantify the e...

Question
Hi all,
I want to measure/calculate foot kinematics and kinetics (midfoot moments and power) using a multi-segment foot model during walking with and without foot orthoses. I was looking at the available literature and I think my two best options would be the Oxford Foot Model and the Rizzoli Foot Model.
Which one is better suited? I'm using the Optitrack/Motive system.
Thanks for your time,
Question
Ideally, I would be able to synchronize the device/system with other systems such as motion capture and EMG systems and force plates. Thanks
