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.
Hip extension involves the action of three muscles contracting in a coordinated sequence. The three muscles are the gluteus maximus(primary mover/agonist), biceps femoris(synergist) and erector spinae(synergist). Any deviation from the specific muscle activation is considered an altered movement pattern. This will cause hip extension dysfunction, muscle imbalance, pain and contribute to changes in posture.
