PURPOSE Surgical transfers of muscles are used to restore lateral pinch in tetraplegia; however, outcomes are variable. The purpose of this study was to compare activation of the brachioradialis (Br) after transfer to the flexor pollicis longus during maximum effort in its primary function (elbow flexion) with maximum effort in its postoperative function (lateral pinch) and to record Br activat...
To determine whether patients with chronic airflow limitation have a specific alteration in skeletal muscle performance, the strength and endurance of inspiratory and limb muscles were compared in 11 patients with chronic airflow limitation and 11 control subjects during maximal voluntary contractions. Peak inspiratory pressure at observed functional residual capacity (FRC) was significantly le...
Previous work has demonstrated that the flexor pronator muscles of the arm (Flexor Digitorum Superficialis, Flexor Carpi Radialis, Flexor Carpi Ulnaris, and Pronator Teres) are primary contributors to varus torques that counter applied valgus torques [3, 5]. These muscles originate on the ulnar side of the distal humerus and have been shown to be highly active during pitching [4]. Additionally,...
INTRODUCTION It is well known that the biceps functions mainly as an elbow flexor and forearm supinator. In vivo elbow flexion and forearm supination strength testing after rupture of the long head of the biceps tendon has shown decreases of 0-16% and 0-21%, respectively [1,2]. Although many studies have attempted to identify the role of the long head of the biceps brachii muscle in elbow flexi...
BACKGROUND The medial collateral ligament provides valgus stability to the elbow. The purpose of the present study was to describe the pathoanatomy of acute traumatic medial collateral ligament ruptures and to report the rationale and results of direct repair. METHODS Between 1996 and 2006, eleven athletes presented with acute rupture of the medial collateral ligament of the elbow and no hist...
The corticospinal system plays an important role in control of voluntary movements in primates. Recently, we demonstrated that the effectiveness of this system is depressed after maximal exercise. Because the depression was absent after antidromic activation of the motoneurons, we argued that transmission across corticospinal synapses was involved. Here, we explore the possible functional conse...
The number of injuries that force golfers to quit is also increasing. In particular, the upper body injuries are concerns for amateur golfers. This study was conducted not only to investigate muscular balance, such as ipsilateral and bilateral ratios of the upper body, but to also evaluate the possible problems of muscular joints in amateur golfers. Male golfers (n=10) and a healthy control gro...
