OBJECTIVE The purpose of this study was to investigate upper-extremity kinematics and range of shoulder motion while wearing a wrist extension orthosis compared to the free hand at initial testing and after a week's wear. METHOD A convenience sample of healthy women, ages 20-50 years, performed a stacking task and a pouring task, freehanded and splinted, at two times, 1 week apart in this cou...

The goal of this study was to investigate clinically relevant biomechanical conditions relating to the setup and alignment of knee-ankle-foot orthoses and the influence of these conditions on knee extension moments and orthotic stance control during gait. Knee moments were collected using an instrumented gait laboratory and concurrently a load transducer embedded at the knee-ankle-foot orthosis...

The possibility to realize highly customized orthoses is receiving boost thanks to the widespread diffusion of low-cost 3D printing technologies. However, rapid prototyping (RP) with 3D printers is only the final stage of patient personalized orthotics processes. A reverse engineering (RE) process is in fact essential before RP, to digitize the 3D anatomy of interest and to process the obtained...

BACKGROUND There are clear indications for benefits of stance control orthoses compared to locked knee ankle foot orthoses. However, stance control orthoses still have limited function compared with a sound human leg. OBJECTIVES The aim of this study was to evaluate the potential benefits of a microprocessor stance and swing control orthosis compared to stance control orthoses and locked knee...

Rheumatoid arthritis of the foot and ankle can be a debilitating problem, particularly for patients who have undergone successful hip or knee arthroplasty. Optimal medical management, use of orthotic devices, and surgical intervention are essential components of patient care. Forefoot involvement with hallux valgus and lesser metatarsophalangeal joint subluxation and dislocation are the most co...

Orthotic therapy is frequently advocated for the treatment of musculoskeletal pain and injury of the lower limb. The clinical efficacy, mechanical effects, and underlying mechanism of the action of foot orthotics has not been conclusively determined making it difficult for practitioners to agree on a reliable and valid clinical approach to their application and indeed even their fabrication. Th...

Our aim was to develop and evaluate a new antipronation foot orthosis that addressed problems perceived by clinicians and users with existing foot orthoses. Clinicians and users were engaged to develop a user specification for the orthosis, and orthotic geometry and materials were developed using clinical reasoning. The orthotic material properties were tested and the ability of the orthosis to...

INTRODUCTION There is limited craniofacial literature on the complications of helmet therapy and controversy regarding the effects of inadequate orthotic helmet therapy. The authors present a case of inadvertently prolonged orthotic helmet therapy after endoscopic strip craniectomy for isolated sagittal synostosis. CASE PRESENTATION A two-month-old Caucasian baby underwent uncomplicated endos...

Orthoses are designed to assist a malaligned foot in adapting to the environment and reduce the frequency of injury. Literature is divided on the benefits of orthotics insoles for postural stability. The current study was conducted to determine the effect of prefabricated orthotic arch supports on postural stabilization. Twelve healthy young adults participated in this study and were tested wit...

Foot pain is a common musculoskeletal disorder. Orthotic insoles are widely used in patients with foot pain. Inexperienced clinicians have difficulty prescribing orthotic appropriately by considering various factors associated the alteration of alignment. We attempted to develop deep-learning algorithms that can automatically prescribe and assess their accuracy. In total, 838 were included this...
