A. Question 2 Locate and palpate the following muscles ⁃ Rectus femoris ⁃ The rectus femoris is a knee extensor. When palpating the rectus femoris you can feel the muscle as it runs dow the middle of the front of the thigh. ⁃ Vastus lateralis ⁃ The Vastus lateralis is a knee extensor. You can palpate the vastus lateralis laterally to the rectus, just below the greater trochanter. ⁃ Vastus intermedius ⁃ The vastus intermedius is a knee extensor. You can palpate the vests intermedius underneath the rectus when you approach your thigh medially. ⁃ Vastus Medialis ⁃ The distal portion of the vastus medals can be palpated medial to the rectus femoris along the lower third of the thigh. The vastus medialis performs knee extension ⁃ When

In healthy individuals, anterior rotation of the innominate occurs during extension of the freely swinging leg. When the innominate anteriorly rotates, it glides inferiorly down the short arm and posteriorly along the long arm of the SIJ. In non-weights bearing an arthrokinematic glide between the innominate and the sacrum occurs during posterior rotation of the innominate and is physiological (i.e., follows the articular surfaces). In weight bearing, the close-packing of the SIJ precludes this physiological glide. Sacral nutation produces the same relative arthrokinematic glide as posterior rotation of the innominate (inferoposterior motion of the sacrum is the same as anterosuperior motion of the innominate); sacral counternutation produces the same arthrokinematic glide as anterior rotation of the innominate (anterosuperior motion of the sacrum is the same as inferoposterior motion of the

My rectus femoris and bicep femoris have also received some toning because these exercises also targeted those muscles. Since those muscles are used in my endurance workouts, I have been able to see visible results in not only my fitness testing results, but my own body as well; I’ve lost some weight in my legs and I’ve got a more firm gluteus maximus. To continue with my third goal of toning my rectus abdominis, I chose to complete an endurance workout because a strength workout would result in gaining muscle mass, which does not achieve my goal. In order to accomplish this, I have done planks, v-snaps, tuck extends, wood chops, side planks, russian twists, hollow holds, running mans, mountain climbers, crossover sit ups, banana rolls and windshield wipers. These exercises fit in with my goals because increasing reps and weight in my core workouts lead to a stronger and tighter core consequently leading to a toned rectus

Lying sideways with the injured leg straightened on the floor, he should cross the uninjured leg in front of the injured one. This will force the injured leg to extend and bear weight. The gluteus maximus’ action is extension, external rotation, and hip abduction. The origin is at the ilium, sacrum, and coccyx, the insertion is at the lateral surface of the greater trochanter, and it is innervated by the inferior gluteal nerve. Lying on the side of the uninjured leg

The infraspinatus is below the scapular spine and attaches to the infraspinous fossa on the scapula (11). The teres minor is found on the lateral border of the scapula (9). The supraspinatus, infraspinatus, and teres minor also share a common tendon attachment in the intertubercular groove of the humerus. The subscapularis is located between the

The directions from the SENIAM link, was very helpful and it was great assistance in the placement. The SENIAM was very specific with pictures, which made it a lot easier to find the muscles (rectus and biceps femoris). Also, using the tape measure to make sure that the electrodes where in the correct places, also made placement easier. As I practiced with taking the sticky plastic off of the electrode, I began to feel a lot more comfortable with taking those off, to place the electrode in the desired location. In the beginning pulling the sticky paper off, was a bit of a challenge.

Examined by Petersen and others in 2013, the main objective of a knee brace is to apply a medially directional force to ensure that the patella does not demonstrate excessive lateral tracking. The study was able to provide Petersen and colleagues (2013) that with the usage of a brace, there is a positive effect in decreasing pain due to the readjustment of the patella in its proper position. Individuals that find knee braces as less than comfortable for them, turn to other techniques, such as taping of the knee in two different manners (Campolo, Babu, Dmochowska, Scariah & Varughese,

The knee joint is also known as tibiofemoral joint. It is a synovial hinge joint formed between three bones which are the femur, tibia and patella (Taylor, n.d.). There are two rounded, convex processes which are known as condyles on the distal end of the femur. The distal end of the femur meets two rounded, concave condyles at the proximal end of the tibia (Tyalor, n.d.). A thick, triangular bone which is known as patella lies anterior surface between the femur and tibia.

Anatomy of meniscus tear Description -3 bones meet to form knee joint: your thighbone (femur), shinbone (tibia), and kneecap (patella). -2 wedge-shaped pieces of cartilage act as "shock absorbers" between thighbone and shinbone. These are called meniscus. They are tough and rubbery to help cushion the joint and keep it stable. (Left) Bucket handle tear.

The pull of the Quadriceps is represented by a vector from the middle of the patella to the anterior superior iliac spine. The Q angle also represents the result of the strong lateral pull of the huge mass of Vastus Lateralis and the correcting the medial pull of the Vastus Medialis. The distal component of the Q angle is identified by a line from the midpoint of the patella to the middle of the proximal tibial tubercle with the Quadriceps relaxed; the normal Q angle is reported to be thirteen to eighteen degrees, angles more than eighteen degrees are associated with increased femoral anteversion.

“The transverses abdominis (Tr.A) is the first muscle activated during lower extremity movements, indicating that it is the primary muscle linked to core stability during lower limb movements. ”3 This makes core strengthening important for the placement of the distal end of the extremity in use at the moment. The function provided here is better placement of the foot when walking or running either on a flat even surface or a rugged hiking trail. The evidence that corroborated this is in an article written by Arti Kaushik and Saurabh Sharma that states: “Core muscle development is believed to be important in many functional and athletic activities, because core muscle recruitment should enhance core stability and help provide proximal stability to facilitate distal mobility.
