AIMS/BACKGROUND The connective tissue system of the levator palpebrae superioris muscle (LPS) consists of the septa surrounding its muscle sheath, the superior transverse ligament (STL) commonly referred to as 'Whitnall's ligament' and the common sheath which is the fascia between the LPS and the superior rectus muscle (SRM). The anterior band-like(More)
OBJECTIVE To determine repeatability of a wireless, inertial sensor-based lameness evaluation system in horses. ANIMALS 236 horses. PROCEDURES Horses were from 2 to 29 years of age and of various breeds and lameness disposition. All horses were instrumented with a wireless, inertial sensor-based motion analysis system on the head (accelerometer), pelvis(More)
OBJECTIVE To determine whether a shoe with an axialcontoured lateral branch would induce greater lateral roll of the forelimb hoof during the time between heel and toe lift-off at end of the stance phase (breakover). Animals-10 adult horses. PROCEDURE A gyroscopic transducer was placed on the hoof of the right forelimb and connected to a transmitter. Data(More)
This study evaluated bacterial isolates obtained during abdominal surgery and their relationship to short-term incisional complications. Samples of peritoneal fluid and from resection and/or enterotomy sites from 49 horses were cultured, with 96% having at least one positive culture result. The most common isolates were Escherichia coli, Streptococcus spp,(More)
OBJECTIVE To test the hypothesis that botulinum toxin type A (BoNT-A) can attenuate lameness associated with acute synovitis in an equine model. DESIGN Four horses 2-6 yrs of age with clinically normal carpi were studied for 15 days. Kinematic gait analysis and clinical measures of lameness were conducted before and after experimental interventions.(More)
OBJECTIVE To assess the analytic sensitivity of an inertial sensor system for detection of the more severely affected forelimb in horses with bilateral lameness. ANIMALS 18 adult horses with forelimb lameness. PROCEDURES Horses were fitted with inertial sensors and evaluated for lameness with a stationary force plate as they were trotted in a straight(More)
OBJECTIVE To compare a sensor-based accelerometer-gyroscopic (A-G) system with a video-based motion analysis system (VMAS) technique for detection and quantification of lameness in horses. ANIMALS 8 adult horses. PROCEDURE 2 horses were evaluated once, 2 had navicular disease and were evaluated before and after nerve blocks, and 4 had 2 levels of(More)
OBJECTIVE To evaluate pelvic movement over a large number of strides in sound horses and in horses with induced hind limb lameness by applying methods to the pelvis that have been described for evaluating vertical head movement in horses with induced forelimb lameness. ANIMALS 17 adult horses. PROCEDURE Horses were filmed while trotting on a treadmill(More)
OBJECTIVE To investigate continuous wavelet transformation and neural network classification of gait data for detecting forelimb lameness in horses. ANIMALS 12 adult horses with mild forelimb lameness. PROCEDURE Position of the head and right forelimb foot, metacarpophalangeal (ie, fetlock), carpal, and elbow joints was determined by use of kinematic(More)
PURPOSE Magnetic resonance imaging (MRI) of the extraocular muscles has attracted growing interest for the evaluation of complex motility disorders. However, little information is available on the high-resolution MRI anatomy of the normal extraocular muscles and their connective tissue system. The study describes the imaging anatomy of the recti and oblique(More)
