Masseter Muscle The masseter muscle is a thick, strong muscle that functions as one of the major muscles of mastication (2,8). The muscle arises from the zygomatic arch and zygomatic bone and inserts inferiorly on the external surface of the ramus of the mandible. The masseter has superficial and deep heads. The superficial head travels distally and posteriorly, attaching near the angle of the mandible. The smaller deep head inserts to the upper region of the ramus of the mandible (2). The masseter

no difficulties and showed no difficulty getting up from a chair. She did not use assistive devices or bracing materials. Full range of motion was recorded in the shoulder joints, elbows, wrists, hands, hips, knees, and ankles. Cervical spine rotation right and left was 80 degrees, with full flexion and extension. The straightaway walk was unremarkable as was the tandem step test, toe lift, heel walk, one-foot stand, and Romberg test. The claimant did not use any assistive devices. Dr. Keown

rotation, adduction, and circumduction. Abduction is the movement of a body part away from the midline, an example of that would be lateral raises using a dumbbell. Another example would be the lateral shuffle. It targets the muscles of the thighs, hips, and buttocks. An extension movement would be the return from flexion and an exercise for this would-be leg extensions. An example of a flexion movement is a hamstring stretch. Rotation is the circular movement of a body segment about a long axis and

Discussion There were few significant differences in knee extensor and knee flexor muscle activity during walking with robotic assistance. Significant differences in muscle activity across condition only occurred in muscles targeted for intervention (knee extensor, VL), with an increase in muscle activity during the EXO condition, a positive result for an extensor muscle. Although some undesirable increases in MH flexor muscle activity were seen in the linear envelopes, they did not present significant

During mid stance the peak height of the hip is seen to be higher on the prosthetic limb than in a non amputee. This is a result of the reduced flexion of the prosthetic knee. Also the characteristic of the prosthetic foot influences the peak height too. After contralateral foot contact an abrupt transition from hip extension to flexion is seen. In the late stance, an eccentric hip flexor activity is seen as compared to normal. This inturn generates higher hip flexor moment. This greater moment further

largest muscle in the body and covers each buttock. The origin of this muscle is the sacrum, coccyx, and ilium. The insertion is the posterior surface of femur and fascia of the thigh which helps to extend the thigh at the hip. The gluteus maximus helps to straighten the limb at the hip when a person walks, runs, climbs, or squats. In the quadriceps femoris group there are four muscles called the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The rectus femoris muscle occupies

The hamstrings contract eccentrically acting as the synergist and help the flexion of the hip to occur. The Rectus femoris of the quadriceps contract eccentrically to help flex the hip, they are co-contracting with the hamstrings. The hip flexors may contract rapidly to stabalise the body on the way down if there is a loss of balance (Wynsberghe et al., 1995). The adductor longus, adductor brevis and adductor Magnus

modified sit-and-reach test and both the shoulder extension and hip flexion tests. For shoulder extension 33% of the variance was accounted for by the modified sit-and-reach and for hip flexion 22% of the variance was accounted for by the modified sit-and-reach. Table 1.

kicking leg. This is the part of them movement that produces power and force essentially transferring over into the next phase. This part of the movement involves a concentric contraction of the gluteus maximus and hamstrings that results in hip extension making the hip rotate internally due to the concentric contraction of the gluteus medias. Knee flexion is the main

Present Technology Good posture is defined as having a forward tilted pelvis and having the rib cage aligned with the pelvis, wide and long shoulders, but not squeezing the shoulder blades, and having an elongated head. When sitting, the torso and the legs should form a 90-degree angle, and the knees should also be at a 90-degree angle. Even though that is the definition of having good posture, sitting position should be adjusted to the user’s comfort. If sitting position is forced, then more harm
