Knee extensor neuromuscular activity was investigated during isometric (60° knee angle), shortening and lengthening contractions (50-70°, 10° ·s-1) corrected for force-velocity related differences in intrinsic muscle strength. However, during dynamic contractions additional factors such as shortening induced force losses and lengthening induced force gains may affect muscle strength and thereby...

OBJECTIVE To evaluate the outcomes of lengthening post-traumatic femoral segments using a recently available magnetic intramedullary (IM) lengthening system. DESIGN Retrospective cohort study. SETTING Urban level II Trauma Center. PATIENTS/PARTICIPANTS Patients treated for post-traumatic femoral shortening at our institution between 2012 and 2015. We identified 17 femurs lengthened (14 me...

BACKGROUND AND PURPOSE Humeral lengthening and deformity correction are now being done increasingly for various etiologies. Monolateral external fixators have advantages over traditional Ilizarov circular fixators; they are easy to apply, they are less bulky, and they are therefore more convenient for the patient. We assessed the effectiveness of hybrid monolateral lateral fixators in humeral l...

UNLABELLED Extension contracture of the knee is a common complication of femoral lengthening. Knee flexion exercises to stretch the contracture with physical therapy can be effective but take a prolonged amount of time to work and place increased stress across the patellofemoral joint. We developed a minimal-incision limited quadricepsplasty surgical technique to treat knee extension contractur...

The purpose of the present study was to test the hypothesis that myofascial force transmission may not be limited by compartmental boundaries of a muscle group to synergists. Muscles of the anterior tibial compartment in rat hindlimb as well as of the neighbouring peroneal compartment (antagonistic muscles) were excited maximally. Length-force data, based on proximal lengthening, of EDL, as wel...

The four experiments reported concern the amount and domain of lengthening associated with focal accents in Swedish. Word, syllable and segment durations were measured in read sentences with focus in di!erent positions. As expected, words with focal accents were longer than nonfocal words in general, but the amount of lengthening varied greatly, primarily due to speaker di!erences but also to p...

In a corpus study using eight pairs of syntactically ambiguous sentences, we conducted acoustic and quantitative analyses of the prosodic patterns used by seven native speakers of the Hong Kong variety of Cantonese to divide these sentences into prosodic words — a phenomenon referred to as “prosodic chunking”. Although pauses, pitch reset and preboundary lengthening were analyzed, in this artic...

The theoretical concepts underlying crown-lengthening surgery are reviewed, and a patient who underwent esthetic crown-lengthening surgery is described. An overview of the various indications and contraindications is presented.

BACKGROUND Limited ankle dorsiflexion has been implicated as a contributing factor to plantar ulceration of the forefoot in diabetes mellitus. The purpose of this study was to compare outcomes for patients with diabetes mellitus and a neuropathic plantar ulcer treated with a total-contact cast with and without an Achilles tendon lengthening. Our primary hypothesis was that the Achilles tendon l...
