STUDY DESIGN Prospective, blinded, diagnostic-accuracy study. OBJECTIVES To investigate the diagnostic accuracy of the ankle anterior drawer test (ADT) to detect anterior talocrural joint laxity in adults with a history of lateral ankle sprain. BACKGROUND The ADT is used to manually detect anterior talocrural joint laxity following lateral ankle sprain injury; however, the diagnostic accura...

High frontal plane knee joint angular impulse has been associated with patellofemoral pain syndrome (PFPS) and knee osteoarthritis (OA) [1,2]. Interventions that reduce frontal plane knee joint loading may provide clinical benefits. Wedged insoles have widely been proposed as one form of such an intervention. It has been shown that a laterally wedged insole can effectively decrease the peak fro...

The joint coordinates systems (JCS) of the hip, knee, and ankle have been extensively described [1, 2, 3]. The principle is to embed a flexion-extension (FE) axis in the proximal segment and an internalexternal rotation (IER) (or adduction-abduction (AA)) axis in the distal segment, following anatomical or functional directions. For the joint displacements, the origins of the proximal and dista...

Kinematic and kinetic changes in the lower extremities occur as an athlete becomes fatigued during vertical jumping; however, specifics of these are not well-understood. Therefore, purpose this study was to quantify influence a sport-specific, jumping fatigue protocol on biomechanics ankle, knee, hip joint. Twenty male varsity athletes performed repetitive standing countermovement squat jumps e...

The current study aimed to investigate the effect of ankle restriction on the coordination of vertical jumping and discuss the influence of energy transfer through m. gastrocnemius on the multijoint movement. Eight participants performed two types of vertical jumps: a normal squat jump, and a squat jump with restricted ankle joint movement. Mechanical outputs were calculated using an inverse dy...

BACKGROUND Ankle joint equinus, or restricted dorsiflexion range of motion (ROM), has been linked to a range of pathologies of relevance to clinical practitioners. This systematic review and meta-analysis investigated the effects of conservative interventions on ankle joint ROM in healthy individuals and athletic populations. METHODS Keyword searches of Embase, Medline, Cochrane and CINAHL da...

Measurements of the subtalar joint neutral (STJN) position and passive range of motion (PROM) of the ankle joint and the subtalar joint (STJ) are often part of a physical therapy evaluation. These measurements may be used in treatment planning, such as in the prescription of specialized shoes or orthoses. Therefore, reliability of these measurements, as they are obtained clinically, must be det...

Today, commercially available ankle-foot prostheses are completely passive, and consequently, their mechanical properties remain fixed with walking speed and terrain. Conversely, normal human ankle stiffness varies within each gait cycle and also with walking speed [1][2][3]. Furthermore, some studies have indicated that one of the main functions of the human ankle is to provide adequate energy...

Purpose: The aim of this systematic review is to report about the clinical use of partial and total fresh osteochondral allograft in the ankle joint. The state of the art of allografts with regard to basic science, procurement and storage methods, immunogenicity, generally accepted indications and contraindications, and the rationale of the allografting procedure have been described. Methods: A...
