Electromyography of pronators and supinators in great apes
We obtained electromyographic recordings from the supinator, biceps brachii, pronator quadratus, and pronator teres muscles of a chimpanzee and a gorilla and from the supinator, pronator quadratus, and biceps brachii muscles of an orangutan as they stood and walked quadrupedally on horizontal and inclined surfaces, engaged in suspensory behavior, reached overhead, and manipulated a variety of foods and artifacts. In Pan troglodytes and Pangorilla…
Electromyography of brachial muscles in Pan troglodytes and Pongo pygmaeus
Electromyographic recordings were taken from all heads of the triceps brachii and biceps brachii muscles and from the anconeus, brachialis, and brachioradialis muscles in a chimpanzee and an orangutan as they stood still and walked quadrupedally on horizontal and inclined surfaces, engaged in suspensory behavior, reached overhead, and manipulated a variety of foods and artifacts. Like the gorilla (Tuttle and Basmajian, 1974a), the chimpanzee and …
Activities of pongid thigh muscles during bipedal behavior
Electromyographic recordings were taken from 12 thigh muscles (or major parts of them) in a gorilla, from 6 thigh muscles in a chimpanzee, and from 2 thigh muscles in an orangutan as they engaged in bipedal positional behavior, including stance, reaching overhead, lunging, leaping and walking. In the African apes, symmetric bipedal stances with hindlimb flexure were accompanied by notable EMG activity in many of the hamstring, quadriceps, and add…
Electromyography of pongid shoulder muscles. III. Quadrupedal positional behavior
Electromyographic (EMG) recordings were taken from 14 shoulder muscles (or major parts of them) in a gorilla, a chimpanzee and an orangutan as they stood quadrupedally and tripedally, descended from elevated substrates, crutch‐walked, and progressed quadrupedally on inclined and level substrates. In the African apes, low potentials commonly (but not always) occurred in the sternocostal pectoralis major, anterior deltoid, supraspinatus and subscap…
Electromyography of pongid shoulder muscles. II. Deltoid, rhomboid and “rotator cuff”
Electromyographic (EMG) recordings were taken of action potentials in the deltoid, rhomboid, supraspinatus, infraspinatus, subscapularis, and teres minor muscles of pongid apes as they spontaneously elevated their arms and engaged in suspensory activity on a trapeze. During brachial elevation, activities of pongid deltoid, rhomboid, supra‐spinatus, infraspinatus and subscapularis muscles basically resemble those of human subjects. The intermediat…
Electromyographic Analysis of Embouchure Muscle Function in Trumpet Playing
A review of the pedagogical brasswind literature revealed that the varying and contradictory opinions concerning embouchure function are based primarily on theory or conjecture. The physical and physiological functions involved have received very limited attention from researchers. This experimental study investigated the possible effects of register, intensity, and subjects' proficiency level on electromyographic potentials (a measurement of mus…
Electromyography of brachial muscles in Pan gorilla and hominoid evolution
Electromyographic studies on brachial muscles in a gorilla indicate that its elbow joint may be especially adapted for knuckle‐walking and suspensory behavior. A close‐packed positioning mechanism that minimizes muscular effort during full extension of the elbow joint is indicated by remarkably low levels of EMG in the brachial muscles, particularly during knuckle‐walking and suspensory behavior on a trapeze. Extension of the elbow joint is facil…
Electromyography of knuckle‐walking: Results of four experiments on the forearm of Pan gorilla
Preliminary results of electromyographic (EMG) studies on the forearm of a gorilla provisionally support the hypothesis that special closepacked positioning mechanisms may characterize the wrist and metacarpophalangeal joints II–V in extant knuckle‐walkers (chimpanzees and gorillas). We recommend that once the bony features, related to these close‐packed positions are clearly identified, they may be employed strategically to discern evidence of a…
