of the ground. The muscles being used to cause extension of the hip and knee are the rectus femoris, vastus lateralis, vastus intermedius and the vastus medialis. The hamstring muscles (semitendinosus, semimembranosus and biceps femoris) and the popliteus muscle help in the flexion of the hip. The gluteus Maximus, gluteus medius and the gluteus minimus muscles also aides in the movement phase causing a concentric contraction in this phase and extension of the hips. The muscles in the wrist,…

neck and head making moving against gravity difficult. At points Aaron presents with extension synergy pattern when startled or excited. His posture is asymmetrical as he keeps his head turned to the left and flexed down.…

movement focuses on the lower half of the body, primarily using the joints in the hips, and the knees, and ankles in both legs. These joints, along with the help from many muscles, allow the necessary movements to be performed, such as plantar flexion, extension, and flexion, in order to execute backwards marching properly During the process of backwards marching, one lifts onto their toes in a fluid motion, this requires the use of the ankle joints. The ankle joint, also known as the…

I have chosen a skill from an extra curricular sport activity I participate in outside of school. It is called skipping. The skill I have chosen is one of the many skills I have learnt from participating and competing in this sport. This skill requires many different muscles, bones, joints and their actions. Before I perform my skill I jump over the rope twice quickly and then slowly once. To jump over the rope, I use flexion to bend my elbow joint, moving my radius and ulna in a circular motion…

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…

Climbing techniques - the drop knee shouldn't be mysterious; here's a few things that everyone should know about it. What is the drop-knee? The drop-knee, also known as the Egyptian, is a rock climbing technique that reduces muscle strain in the arms. This technique let's you rotate into the rock and use your hips to push upward.

If you did not know, I had a series of knee surgeries that used to cause me so much pain and agony. I thought I was going to be in pain for the rest of my life but that is definitely not the case anymore. For 3…

lata (the iliotibial tract). Fascia lata later inserts laterally at the tibia and fibula. Thus, gluteus maximus and tensor fascia lata aid in providing lateral stability to the knee. The action of gluteus maximus muscle is with the pelvis fixed, extension and lateral rotation of the femur and with the femur fixed it will extend the pelvis on hip. It mainly extends the flexed thigh at the hip joint. It is insertion into the iliotibial tract, it also stabilizes the knee and…

Even though Hippotherapy may be used with several people or groups, for the purpose of this activity we will concentrate only in one person in order to deliver better results. The following routine typically lasts 30-60 minutes and will illustrate how a session of Hippotherapy should be: 1. In order to increase sensory integration and also help bond with horse, we will introduce the horse to our patient and those who are physically capable can brush and tack, or dress the horse. 2. We will…

The person performing the activity I observed is a 24-year-old male who stands 5 feet 9 and a half inches and weighs 145 pounds. His ethnicity or race is half-Vietnamese and half-Filipino. He wears glasses, has a thin petite build and a trim figure. He played soccer before, continues to go workout a few times a week, and is taking a karate class which lasts 2 hours per week so I know that he is somewhat fit. I could say that his body posture is not “normal” because his back is a little bit…
