Knee problems in adolescents Today we talk about knee problems in adolescents. The knee is a joint that suffers so much more for the activities of daily living such as sports. If we add to this age, we realize that not only wreaks havoc aging, but the period of development and growth is also critical for this joint . Knee problems in adolescents: Causes, symptoms and types. Let's talk about two different situations. First, of that or those diseases that occur in adolescents, due to the body…

Assessment of the Injured Ankle I. Injury Situation: A female volleyball player was in practice and was involved in a blocking drill. When she made the attempt to block the attacker on the other side of the net, they both landed on the center line causing her to come down on the attacker’s foot. This caused the ankle to roll over the outside of her foot. II. Evaluation of the Injury: pain and swelling is localized to the lateral side of the ankle, some inability to bear weight after injury…

Foot Contusion A foot contusion is a deep bruise to the foot. Contusions are the result of a blunt injury to tissues and muscle fibers under the skin. The injury causes bleeding under the skin. The skin overlying the contusion may turn blue, purple, or yellow. Minor injuries will give you a painless contusion, but more severe contusions may stay painful and swollen for a few weeks. CAUSES This condition is usually caused by a blow, trauma, or direct force to your foot, such as a heavy object…

The knee joint is classified as a type of synovial joint, which is one of the most common and complex joints found in the human body. The knee is a meeting point for the femur, fibula, tibia, and the patella. In order to maintain its flexibility and function, several other ligaments join the knee joint in order to keep the attaching bones in place. The knee is the joint where the femur and the tibia meet; the patella (kneecap) is made of bone and sits in front of the knee. The knee joint is a…

There are have been anywhere from 150,000 to 200,000 ACL injuries within a given year reported. Female athlete have a higher injury rate compared to males. In fact, female are 4-8 times more likely to tear their ACL. As many as 70% of ACL injuries are involved in little to no contact with the other player. Why is it that female athlete’s suffer from this injury more than male? The anterior cruciate ligament is located deep in the middle of the knee. It is one for four vital ligaments that helps…

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…
