BACKGROUND: Stance control knee-ankle-foot orthoses (SCKAFOs) ensure knee stability by locking during stance while allowing knee flexion during swing. Differences in function of the knee joints and building principles between devices may affect their effectiveness. OBJECTIVE: To investigate the preliminary effectiveness of a NEURO TRONIC on safety outcomes, net energy cost (EC), and user experiences in individuals already using an E-MAG Active SCKAFO. STUDY DESIGN: Prospective uncontrolled intervention study...

BACKGROUND: Pes planovalgus (PPV) is common in children with cerebral palsy and can cause pain and gait alterations over time. Initial treatment of flexible PPV includes orthotics, despite a lack of consensus on the type of orthosis. We developed an innovative ankle-foot orthosis (RAFO). RAFO is a one-piece orthosis designed to correct both the valgus and the flat of the foot. Its conception situated above the malleolar enables a moderate anti equinus effect. Its precise description and fabrication's process is detailed...

INTRODUCTION: Carbon fiber custom dynamic orthoses (CDOs) have been shown to effectively reduce pain and improve function in military service members with lower-limb impairment, but data are limited for civilians. OBJECTIVES: To evaluate the long-term outcomes of individuals who completed a CDO-centric care pathway in a civilian clinic by comparing baseline pain, mobility, and function with outcomes at long-term follow-up. To identify baseline characteristics and postintervention outcomes predictive of outcomes at long-term follow-up...

OBJECTIVE: Trigger finger is a common clinical disorder that often results in pain and functional limitations. This study aimed to determine whether joint-blocking orthosis was effective in treating adult idiopathic trigger fingers. METHODS: Fifty-five participants were randomly assigned to either a hand therapy group or an orthosis group that immobilized the proximal interphalangeal joint for 6 weeks. The Green classification of triggering; short-form version of the Disabilities of the Arm, Shoulder, and Hand; and numeric pain rating scale were used to assess participants' data...
