Semitendinosus muscle

Aaron had limitations in ROM of UE due to protraction and elevation of the shoulders. He arms stay in a flexed position in sitting, however in supine he has a strong extensor synergy. Aaron’s tone is asymmetrical in that his right side is more affected then his left. There was no observed voluntary movement of his UE. Strength was not tested due to tone. The LE was not tested for tone, strength or ROM due to subluxation of his hips at this time, however LE tone was observed as high extensor tone. The tone is low in his trunk, 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. The child’s voluntary movement was limited, however was able to move head from flexion back into extension in sitting after therapist-facilitated movement. He showed the best movement in this sitting position as he worked on head control with the therapist. During this he used oral reactions when he brought his head upright, he did however fatigue quickly. As his head came up his arms extended out into extension, this is evidence of a STNR. Involuntary movement was observed as clonus reflex occurred in BUE in response to testing tone. Primitive phasic grasp reflex was also observed after the clonus reflex subsided. The child’s ability to move in and out of positions was not observed, as the therapist placed him in positions. Second:…

Being a biarticular muscle group it may be stretched to extremes. When hamstring tears occur during kicking, either slow or fast movement, it involves concurrent hip flexion and knee extension. At deceleration, these muscles will contract, while being promptly lengthened. Therefore, they are performing eccentric contractions (Garrett et al, 1990.). It is well established that repeated eccentric contractions have the potential to damage muscle fibres (Armstrong et al,…

1. The major surface muscles include the following: Trapezius, Deltoids, latissimus dorsi, Pectoralis major, Biceps, Triceps, Rectus femoris, bicep femoris, semitendinosus, Gluteus muscles, abdominals, Lateral Gastrocnemius, serratus dorsi, external oblique, and soleus. Trapezius- Origin: Upper: Base of skull, Occipital protuberance and posterior ligaments of neck. Middle: spinous process of 7C and T1-T3 Lower: Spinous process of T4-T12 Insertion: Upper: Posterior aspect of the lateral…

lower back or leg pain. For proper body mechanics you must have the “load” close to your body, trunk in an upright position, and use the muscles in the leg instead of the back (Early, 2013 pg 191).Proper body mechanics for the activity of tug of war, would be to stand in a staggered squat position, with one foot out while the other is lined up with the hip. Secondly, your trunk should be upright, even while pulling on the rope the trunk should remain in an upright position. Use your leg muscles…

rigid when you kick so that no power is lost. Your knee joint, consisting of the tibia and femur, extends as your thigh muscles contract and your hip, which is made up of your femur and ilium, swings forward in a movement called hip flexion. Muscles of the Lower Leg: The primary muscles in your lower leg used in kicking a football are on opposite sides of your tibia, or shin bone. Your gastrocnemius and soleus muscles, collectively called your calf, contract to…

Electrical stimulation: Eight self-adhesive 7x13 cm oval carbon electrodes were adhered to the skin over the quadriceps and hamstring muscles (four electrodes per leg). These muscles were selected because of their ease of access, clinical importance, and large size, which we reasoned would yield the greatest potential for altering energy expenditure. The distal margin of the distal quadriceps electrode was placed over the distal-most palpable border of the vastus lateralis. The proximal…

The hamstring consists of a group of three muscles; the Biceps Femoris, the Semitendinosus, and the Semimembranosus all of which run along the back of the leg just above the knee. These muscles are vital to the proper function of the knee and leg and can affect a person's ability to walk, run, kick, and perform other physical activities at full strength. One of the most important jobs of the hamstring is knee flexion, but the hamstring also helps the upper body distribute its weight evenly over…

athletes of any sports that requires sprinting. According to Verrall (2001), 20% of all missed games in Australian Rules Football is due to a hamstring injury. Hamstring injuries are classed into three; Grade I which is mild involves tearing of a few muscle fibres, grade II is moderate and involves a more severe tear and grade III is severe with a complete rupture of the musculotendinous unit ((Kilcoyne, Dickens, Keblish, Rue & Chronister, 2011). An athlete suspected with hamstring injuries…

(Berglund et al, 2015). The Biering-Sorensen test evaluates the hip and back extensor muscles aerobic capacity. This rehabilitative exercise also helps to improve a reduction in the pain intensity the patient experiences. Furthermore, improvement is seen in the lumbopelvic movement control, which allows for a larger range of motion (Berglund et al, 2015). The deadlift requires muscles from all across the body to complete the action in its…

types of muscles within the human body that aid the body with movement while a few also helps with stabilizing the bones (Allen and Harper 2014). Skeletal, cardiac, and smooth are the three types of muscular tissues found within the body (Tortora and Derrickson 2014). The heart is made out of cardiac muscle tissue and that is striated (Tortora and Derrickson 2014). The walls of the hollow organs of the human body are made with smooth muscle tissues that are non-striated (Tortora and Derrickson…
