This study examined the effect of the surgical approach used in total hip arthroplasty (THA) on gait mechanics six months following surgery. Quantitative gait analysis was performed on 29 subjects: 10 anterolateral (A-L) and 10 posterolateral (P-L) THA patients and nine able-bodied, velocity-matched subjects. Discriminant function analysis was used to(More)
OBJECTIVES Considerable information exists concerning the differences in motoneuron pool (MP) excitability between young and elderly subjects. A recent study demonstrated decreased heteronymous Ia facilitation with aging, suggesting increased presynaptic inhibition (PI) with increasing age as a mechanism for this change (Morita et al., Exp Brain Res 104(More)
The purpose of this study was to examine the accuracy of the Runs Test, Reverse Arrangements Test, and modified Reverse Arrangements Test for assessing stationarity of surface electromyographic (EMG) signals. Five stationary signals were generated by custom programs written with LabVIEW programming software. These signals consisted of sine waves, sums of(More)
Despite an increase in women sports participants and recognition of gender differences in injury patterns (e.g., knee), few normative strength data exist beyond hamstrings and quadriceps measures. This study had 2 purposes: to assess the lower-extremity strength of women (W) and men (M) basketball players who were 9-22 years old, and to determine which(More)
BACKGROUND Pure Lisfranc ligament injuries have a varied clinical presentation, making them difficult to diagnose. This study seeks to understand in vivo strain characteristics of the dorsal Lisfranc ligament under clinically relevant stress loads and foot orientations measured by ultrasound. METHODS Randomized ultrasound imaging trials were performed on(More)
Bilateral symmetry of the ligaments is a common assumption used as an intrasubject control for clinical diagnosis. The present study investigated the bilateral symmetry of the dorsal Lisfranc ligament (dLL) using ultrasound. Data were acquired from 50 asymptomatic subjects in a seated position at a loaded calf raise machine equipped with a force plate. The(More)
BACKGROUND Research findings have linked dorsal Lisfranc ligament (dLL) rupture to complete Lisfranc ligament complex rupture; identifying deformation characteristics of the dorsal Lisfranc ligament alone may be helpful in diagnosing complete ligament rupture. The goal of the present study was to assess the deformation characteristics of the asymptomatic(More)
Tape has traditionally been used to support the ankle during activity. More recently, commercial ankle braces have been worn as an alternative. The cumulative information on the effects of taped versus braced ankle support or interbrace comparisons is inconclusive. With few exceptions, ankle brace studies have collected data soon after support conditions(More)
BACKGROUND Painful diabetic neuropathy remains a difficult pathologic condition to manage effectively despite numerous pharmacologic interventions. A randomized, placebo-controlled, double-blind study was undertaken to determine whether topical 5% ketamine cream is effective in reducing the pain of diabetic neuropathy. METHODS Seventeen diabetic patients(More)
This retrospective study aimed to determine if a transverse plane forefoot relationship exists in patients with Jones fractures. Anteroposterior radiographs of 30 acute Jones fractures were compared with radiographs of 30 asymptomatic control subjects. Radiographic metatarsus adductus angle measurements were analyzed with a digital software program. The(More)
