Extensor carpi ulnaris muscle

grip strength (p. 331). Because of this, individuals are unable to participate in their daily activities and occupations which require their hand, wrist, or forearm. If an individual performs forearm rotation following an injury, they will likely feel a popping or clicking sensation in the area. This sensation could be due to the lack of stability, or an impingement in the area. As the TFCC is an area located in the ulnar side of the wrist, there are a number of muscles around it. Domire, Karabekmez, Duymaz, Rutar, Amadio, and Moran (2009), stated the extensor carpi ulnaris muscle is often impacted amidst this injury (p. 807). The extensor carpi ulnaris is impacted because this injury will likely cause tendons to rub on one another, and this muscle is generally in the location most effected. This could potentially lead to other injuries, such as tendinitis. Domire et. al. (2009) also stated the moment arm of the extensor carpi ulnaris muscle is increased, which increases the maximum amount of moment produced by the muscle (p. 807). If the length of moment is changed, the amount of force required to produce a movement would then also be altered, leading to a change in body mechanics. When an individual thinks TFCC is their possible injury, there are a number of ways either a doctor or therapist could potentially lead to a diagnosis. It is very common for the diagnostic process to initially begin by a physical examination. If the physician or therapist notices the patient has…

elbow. Frequently seen in sports that require a repetitive motion of forearm flexion and extension, such as tennis, pitching, golf, javelin throwing, and fencing, the muscles that are typically involved, but are not limited to, include the extensor muscles.(1) This muscle group encompasses the extensor carpi radialis brevis and the extensor digitorum communis laterally. In addition,but not as prevalent with athletic injuries regarding the forearm complex, the pronator teres, flexor carpi…

in order to instruct a volleyball player on the correct qualitative and quantitative aspects of a serve. Particular movements for a volleyball serve, encompass both structural and mechanical fundamentals essential to the functionality of the movement. Using both kinesiology and biomechanical analysis, the volleyball serve may be better understood. When studying the specific anatomical features of a volleyball serve, the movements are most efficiently analyzed in smaller phases. Using kinesiology…

al 2012). Pain and discomfort is felt in the area located over the lateral epicondyle, the origin for all of the extensors in the forearm (Jariwala A. et al 2012). Lateral epicondylitis affects the tendinous tissue of the lateral epicondyle of the humerus as well as the extensor muscles;…

The intrinsic muscles include the thenar and hypothenar muscle group in the thumb and pinky, the interossei muscles by the dorsal and palmar, originating between the metacarpal bones, and the lumbrical muscles by the deep flexor tendon. The intrinsic muscles only make the fingers function. The extrinsic muscles are the long flexors and extensors, running from the forearm to the hand, providing strength to the hand and wrist. The flexors prohibit the fingers to bend and the extensors can make the…

major key in sports as it dissects the certain movement of muscles and joints to perform a certain action in the sport. A basketball jump shot uses all of the movement phases, from the stance phase, preparatory phase, movement phase, follow-through phase and recovery phase. The jump shot has gradually evolved in the NBA, and is considered one of the most important and most commonly used shot in basketball. There are many sharpshooters in the NBA, like Kevin Durant, Stephen Curry and Carmelo…

lower back or leg pain. For proper body mechanics you must have the “load” close to your body, trunk in an upright position, and use the muscles in the leg instead of the back (Early, 2013 pg 191).Proper body mechanics for the activity of tug of war, would be to stand in a staggered squat position, with one foot out while the other is lined up with the hip. Secondly, your trunk should be upright, even while pulling on the rope the trunk should remain in an upright position. Use your leg muscles…

The human body is composed of muscle which are responsible for body movement. Muscles in found in the human body attach to the bones of the skeletal system, in a human body there are “700 individual muscles that make up part of a person’s weight and the muscular system. Each of these muscles are separate organ which are made up of skeletal tissues, nerves, blood vessels and muscle tissues. Muscle tissues are found throughout the human body, inside the heart, the blood vessels and the digestive…

with similar anatomy, the bear is mostly a quadruped mammal, but is capable of bipedalism, while humans are bipedal mammals. In humans, the hand is meant for a variety of different flexing hand movements allowing for very specific holding and gripping. Meanwhile, in a bear forearm and paw they bring much more strength to carry the massiveness of the body of the bear while walking and running. I hypothesize that the paw muscles and bones in a bear will be much larger in size but much less in…

Surface Electromyography Amplitude During Sustained Isometric Contractions Connor Howe 31451131 HMKN 310 UBC Okanagan Greg duManoir October 18, 2015 Introduction Muscle fatigue is the result of a series of structural, metabolic and energetic changes in muscle fibers caused by changes in nervous system efficiency as well as decreased oxygen and nutrient supply (Cifrek, Medved, Tonković, & Ostojić, 2009). A major driving force behind muscle fatigue is lactate buildup. As lactate builds…
