An acute, focal neurologic deficit is the hallmark of stroke. Major strokes involve both motor and sensory components. Symptoms may be sudden and maximal at onset (embolic) or intermittent and stuttering (thrombotic). Findings in stroke syndromes depend on the territory of brain suffering infarction.
The primary mover during the seated or lying leg extension exercise is a group of four muscle heads on the front of the thigh, collectively referred to as the quadriceps. The largest muscle head is the rectus femoris, which sits in the center of the front thigh.
Muscle pairs. Antagonistic pairs of muscles create movement when one (the prime mover) contracts and the other (the antagonist) relaxes. Examples of antagonistic pairs working are: 1  the quadriceps and hamstrings in the leg.2  the biceps and triceps in the arm.uscle pairs.
