OBJECTIVE The use of muscle balancing by the clinician to determine return to activity or discharge of a patient is not a well understood measure. Because of the lack of information on the poorly understood concept of eccentric/concentric (E/C) ratios at the ankle, the purpose was to determine the E/C ratios for the invertor and evertor muscles at various(More)
Considerable variability exists for isokinetic testing of the shoulder rotators, leaving the clinician in a quandry concerning the most appropriate method for patient evaluation. The purpose of this study was to evaluate concentric and eccentric rotational strength in the scapular and neutral planes for the surgical and nonsurgical shoulders. Fifteen males(More)
Although a number of mechanical and neuromuscular processes have been identified, the primary mechanisms underlying residual functional instability of the ankle remain unclear. Understanding such mechanisms will help physical therapists identify where to focus treatment efforts, ultimately leading to more effective rehabilitation. In the present(More)
The relationship between repetitive trauma and propensity for ulceration and ulcer healing is unknown in part because of the lack of accurate information on activity level. The Step Activity Monitor (SAM) is a newly designed accelerometer to record activity level, but its accuracy is questionable. The purpose of this study was to determine the accuracy of(More)
External orthotic supports or braces are used clinically to treat individuals with chronically unstable ankles. Braces have efficacious effects on dynamic strength, passive tissue tension, and proprioception, but their effects on gait remains undetermined. The purpose of this study was to determine if overground locomotion, including walking up a step and a(More)
The purpose of this study was to determine the effect of different TENS stimulus characteristics on ulnar motor nerve conduction velocity (MNCV) in the forearm and on forearm and ring finger skin temperatures. Thirty-one healthy women consented to receive conventional, acupuncture-like and placebo TENS: one treatment being randomly administered on each of 3(More)
Total contact casts (TCC) are commonly used in the treatment of neuropathic ulcers of the foot related to diabetes. However, casts may alter the gait pattern and increase loading parameters of the contralateral foot. We determined the effects of total contact casting on plantar pressure parameters for the contralateral extremity. Ten healthy subjects(More)
Although previous studies have been conducted to ascertain the outcome of rotator cuff repair, the greatest majority have utilized subjective evaluation. The purpose of this study was to objectively compare the strength, as determined isokinetically, of the muscles around the shoulder complex a minimum of 1 year following surgical rotator cuff repair.(More)
Numerous electrical stimulation (ES) papers have been published using a variety of electrode placements and muscle tension criteria levels, making cross-comparisons difficult. The purpose of this study was to compare isometric knee extensor torques produced using three methods to induce muscle tension and three electrode placements. Twenty-three healthy,(More)
Functional ankle instability, orthoses, and passive resistive torque tolerated have not been researched. The purpose of the study was to evaluate the passive resistance torque exerted by a flexible and semirigid orthosis for individuals with chronic instability. Twenty-two subjects were evaluated on the passive ankle resistance unit during unbraced,(More)
