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.
The leg extension exercise involves extending, or straightening, the knee against resistance in a seated, lying or standing position. Although an effective upper thigh exercise, the leg extension only targets a small area of the leg musculature through one joint movement, knee extension.
