Overuse injuries, (as opposed to acute traumatic events) are the most common mechanism for injury in dance, accounting for 68% in females and 60% in males. (Allen, 2012) Therefore the strength and conditioning plan should focus on strengthening the affected structures without exposing them to undue repetitions so as not to exacerbate this effect. (Allen, 2012) Lower back strain is the single most common complaint of ballet dancers (40% exhibited it in one study), followed by ankle sprains and…

Secondly, the length of residual femur affects hip muscle strength too. The force can be generated by a muscle is affected by the muscle force magnitude and the distance from the muscle attachment to the axis of rotation (Rassier et al., 1999). For example, the force can be generated by gluteus maximus is reduced if femur residue length is shorter. Therefore, amputees need to recruit more motor units in order to generate adequate force in walking. This can rationalise energy expenditure on…

Question 1 Biceps brachii-found in the arm with two heads, and is parallel with the body. "At the point when a parallel muscle contracts, it abbreviates and gets bigger in measurement". Extensor digitorum-a lower arm muscle that develops the finger joints is uni-pennate. Flexor carpi Muscles-Allows the wrist to flex and snatch, it is a shaft muscle shape with a long ligament. Transversus abdominis-its umbrella molded and is for stance arrangement and is situated in the stomach. Rectus femoris-Is…

posterior cruciate ligament (PCL). The presented picture shows the tibia being pushed back posteriorly. The PCL, within the knee joint, prevents posterior translation of the tibia bone related to the femur bone (Moore et., al, 2014). If the PCL is torn, then the tibia can move backward too much leading to instability of the knee. The knee joint serves as a hinge joint that connects the femur to the tibia allowing for flexion, extension, and minimal internal/external rotation. The tibial…

Plantar Fasciitis is the number one leading cause in foot pain. The plantar fascia is a flat ligament that connects the heel bone (Calcaneus) to the toes and it also helps to support the arches underneath both of the feet. When the plantar fascia gets pulled or inflamed then you will feel the bottom middle of your foot pulling or stretching out and will usually hurt. It will usually hurt most when you are walking or standing to put pressure on the foot. Most athletes or middle aged people who…

Volleyball is competitive, as are all sports, and can be dangerous if the techniques are not done correctly. One of the most common injuries in volleyball is an ankle sprain. The ankle contains 14 bones and 3 ligaments, that can be broken and torn. Another injury that can occur when playing volleyball is the tear of ligaments in the knee or ACL. Although knee damages are a big injury while playing volleyball, sprained ankles are more common because players often land on the outside part of…

patient’s pain might be caused by an intra-articular or extra-articular problem and may be the result of his injury or not. Thus, the differential diagnosis for his chronic ankle pain is quite broad. Because there are so many potential causes for joint pain, every new patient who comes to the rheumatology clinic needs a thorough history and a physical examination. During the history, I encourage the patient to tell the…

is an inflammation and swelling of the cartilage and lining of the joints, generally accompanied by an increase in the fluid in the joints. Arthritis is a disabling and occasionally crippling disease afflicting almost 40 million Americans. Although the prevalence of and pain associated with arthritis increases with age, all people from infancy to middle age have the potential to have the disease. Because the feet have 33 joints that can be afflicted by arthritis, and there is no way to avoid…

A muscle tear refers to muscle fibers being damage (Virginia 2013). A tear in the gastrocnemius can cause great risk of injury since the gastrocnemius is located between the knee and ankle joint (Virginia 2013). This can be cause by direct trauma to the calf region or sudden landing on the foot (Medial Head Gastrocnemius 2006). This injury is common in tennis players due to the constant motions of jumping and lunging (Medial Head Gastrocnemius 2006). In the first degree of gastrocnemius tear,…

Osteoarthritis is the most common reason for people to get a knee replacement in the US, and now a better and cheaper form has emerged for knee replacements. 3D knee replacements Many knee replacements are caused by osteoarthritis and researchers have found that a gene called FAAH is higher in people who have osteoarthritis. FAAH is fatty acid amine hydrolase, which is a membrane hydrolase with a single N-terminal transmembrane domain. In the past, the FAAH gene has been directly correlated…
