The effect of elbow position on biceps tendon reflex.
BACKGROUND Testing of tendon (T) reflex is the basic method used in the diagnostic procedure of clinical neurology. Measurement of T reflexes precisely can be a valuable adjunct to clinical examination. Quantification of T reflexes may provide more accurate results. AIMS To analyze the effect of elbow position on biceps T reflex. SETTINGS AND DESIGN A self-controlled clinical trial of bicep...
متن کاملThe effect of biceps reattachment site.
BACKGROUND We hypothesize that an anatomic repair of the distal biceps tendon would recreate native tendon moment arm and forearm rotation, while a nonanatomic insertion would compromise moment arm and forearm rotation. METHODS Isometric supination torque was measured at 60° of pronation, neutral, and 60° of supination for the native distal biceps tendon and 4 repair points in 6 cadaveric spe...
متن کاملVariation of muscle moment arms with elbow and forearm position.
We hypothesized that the moment arms of muscles crossing the elbow vary substantially with forearm and elbow position and that these variations could be represented using a three-dimensional computer model. Flexion/extension and pronation/supination moment arms of the brachioradialis, biceps, brachialis, pronator teres, and triceps were calculated from measurements of tendon displacement and jo...
متن کاملDiagnosis and treatment of distal biceps and anterior elbow pain in throwing athletes.
Despite the activity of the musculature around the elbow and the high angular velocity and stresses, distal biceps tendon injury is rare in the overhead athlete. The biomechanics of the throwing motion and electromyographic studies of the elbow provide useful clues as to why the biceps stays relatively healthy. Anterior elbow complaints are not uncommon in this population and can easily be mist...
متن کاملDistal biceps tendon rupture: an in vitro study.
BACKGROUND Options for repair of distal biceps tendon ruptures are well-described. However, scant data exist in the literature regarding failure strength of the native tendon. We hypothesize that a) the distal biceps tendon failure strength is sensitive to loading angle, and b) the failure strength is greater than what has been previously reported in the literature. METHODS 15 radii were pott...
