INTRODUCTION: Inverse dynamics joint kinetics are often used to infer contributions from underlying groups of muscle-tendon units (MTUs). However, such interpretations are confounded by multiarticular (multi-joint) musculature, which can cause inverse dynamics to over- or under-estimate net MTU power. Misestimation of MTU power could lead to incorrect scientific conclusions, or to empirical estimates that misguide musculoskeletal simulations, assistive device designs, or clinical interventions...

BACKGROUND: This study investigated the effect of Vibram FiveFingers Bikila minimalist shoes on intrinsic foot musculature. We hypothesized that a gradual transition into minimalist shoes will increase the thickness of the abductor hallucis muscle. METHODS: Forty-one individuals were divided into four groups: control (traditional shod) (n = 9), restricted walking in Vibram FiveFingers (n = 11), running in Vibram FiveFingers (n = 10), and unlimited walking in Vibram FiveFingers (n = 11)...

CONTEXT:  The intrinsic foot muscles maintain the medial longitudinal arch and aid in force distribution and postural control during gait. Impaired intrinsic foot-muscle function has been linked to various foot conditions. Several rehabilitative exercises have been proposed to improve it; however, literature that identifies which individual muscles are activated during specific intrinsic foot-muscle exercises is lacking. OBJECTIVE:  To describe changes in activation of the intrinsic plantar foot muscles after 4 exercises as measured with T2 time magnetic resonance imaging (MRI)...

OBJECTIVE: The spastic hemiplegic patient often presents dystonia of extensor hallucis longus (EHL) and, more rarely, extensor digitorum longus (EDL). This dystonia is difficult to treat by tendon lengthening, because its primum movens is purely neurological without retraction musculo-tendinous. A hyponeurotisation by partial section of the branches of the common and deep fibular nerve(s) could be a therapeutic alternative to botulinum toxin injections. Its technique has never been described...

OBJECTIVE: Fibula and leg muscles play an important role during gait. The vascularized free fibula flap (VFFF) harvesting procedure could have an impact during short walking distance [1]. However, little is know about the VFFF effect during prolonged walk conditions [2]. The aim of this study was to determine the effect after VFFF harvesting on the evolution of spatiotemporal gait parameters during a 6-Minutes Walk Test (6MWT) and to compare results with those found in healthy persons...

: Introduction Flexor hallucis longus (FHL) tendon transfer to the calcaneus is commonly used in the surgical treatment of chronic Achilles tendinopathy. This study assesses the integrity of FHL tendon biotenodesis screw fixation with respect to 2 variables: incorporation of a terminal whipstitch and tunnel depth. Materials and methods A total of 60 fresh-frozen cadaver FHL tendons and 28 calcanei were harvested for analysis in 4 sets of fixation constructs; 14 whipstitched tendons were compared against their nonwhipstitched paired tendon via pull-out strength load testing, and 16 tendon pairs were randomized for fixation in either a full-depth tunnel (bicortical) or a 25-mm partial tunnel (unicortical)...

BACKGROUND: Patients with chronic ankle instability (CAI) have demonstrated altered neuromuscular function and decreased muscle strength when compared with healthy counterparts without a history of ankle sprain. Up to this point, muscle volumes have not been analyzed in patients with CAI to determine whether deficits in muscle size are present following recurrent sprain. PURPOSE: To analyze intrinsic and extrinsic foot and ankle muscle volumes and 4-way ankle strength in young adults with and without CAI...

BACKGROUND: The list of indications of posterior ankle endoscopy is expanding and includes various soft tissue and bony pathologies of the posterior ankle. Some of the indications, e.g. release of frozen ankle, debridement of posteromedial soft tissue impingement of the ankle and debridement or fixation of the posteromedial osteochondral lesion of the talus, require approach to the posterior ankle medial to the flexor hallucis longus tendon. The purpose of this study was to assess the risk of injury to the posterior tibial neurovascular bundle during posterior ankle endoscopy...
