Functional recovery following sciatic, tibial, and peroneal nerve injury was assessed over a 1-year period using walking track analysis in the rat. Internal neurolysis did not affect nerve function. Crush injury induced a temporary, but complete, loss of function that recovered to control levels by 4 weeks. Nerve transection resulted in complete loss of(More)
The degree of self-mutilation (autotomy) following sciatic nerve injury was assessed in 6 rat strains. Experimental groups included sciatic nerve transection with and without repair and crush lesions. The degree of autotomy was measured using a standard grading system. There were statistically significant differences between the strains in the transected(More)
Functional assessment of rat sciatic, tibial, and peroneal nerve injuries was performed using walking track analysis. Individual walking print length (PL), toe spread (TS), and intermediate toe spread (ITS) values were measured up to 24 weeks after specific nerve transection, with or without repair. Sciatic and tibial nerve manipulation initially affected(More)
OBJECTIVE The purpose of this study was to investigate effects of carpal tunnel syndrome (CTS) on digit force control during a sustained precision pinch. METHODS Eleven CTS individuals and 11 age- and gender-matched healthy volunteers participated in the study. The subjects were instructed to isometrically pinch an instrumented apparatus for 60s with a(More)
This study evaluated the hypothesis that upper extremity function and range of motion can be quantified reliably in children with cerebral palsy (CP) in a busy clinical setting. The specific aim was to determine the inter- and intrarater reliability of a modified House Functional Classification (MHC) system to evaluate upper extremity function and a(More)
INTRODUCTION Extensor tendon irritation and attritional tendon ruptures are potentially serious complications after open reduction and internal fixation of distal radius fractures. These complications are well recognized after dorsal plating of distal radii; and these are now being reported after errant screw placement during volar fixed-angle plating.(More)
The development of a nerve bank as a source of donor material to repair large defects in peripheral nerve injuries requires an understanding of the influence of cold storage on cell viability and function in these potential nerve grafts. Segments of peripheral nerves from both human and rat were stored in University of Wisconsin Cold Storage Solution (UW)(More)
Recovery of function is of prime importance after peripheral nerve injury and repair. This paper describes a method of obtaining and measuring walking-tracks and generating a Sciatic Function Index (SFI) to quantify functional sciatic nerve recovery in the rat. The reader is provided with a series of walking-tracks to measure, analyze and compare to those(More)
Selective reinnervation was studied by comparing the regeneration across a conventional neurorraphy versus a conduit nerve repair. Lewis rats underwent right sciatic nerve transection followed by one of four different nerve repairs (n = 8/group). In groups I and II a conventional neurorraphy was performed and in groups III and IV the proximal and distal(More)
BACKGROUND Carpal tunnel syndrome (CTS) compromises fine sensorimotor function during activities of daily living. Reach-to-pinch for a small object requires not only dexterity of the grasping digits, but also coordinated transport of the hand to the target. This study examined the effects of CTS on the kinematic performance of reach-to-pinch maneuver. (More)
