Cranial nerve:
Olfactory impairment – inability to detect odors.
Visual impairment – visual field defects, pupillary changes, eye muscle impairment
and facial nerve impairment.
Auditory problems – hearing loss and vertigo.
Speech and swallowing impairment – aphasia and dysphagia.
Constructional problems – apraxia and agnosia.
Muscle movements:
Tics – sudden uncontrolled movements of the face, shoulders and extremities.
Tremors – involuntary, repetitive movements in the fingers, wrists, eyelids, tongue
and legs.
Fasciculations – fine twitching in small muscle groups.
Spastic gait – is a stiff, foot-dragging walk caused by unilateral leg muscle
hypertonicity; the foot tends to drag or shuffle, scraping the toes on the ground.
Scissors gait – the legs flex slightly at the hips and knees so that the person looks
like he is crouching. With each step, the thighs adduct and the knees hit or cross in a
scissor-like movement.
Propulsive gait – is characterized by a stooped, rigid posture – the head and neck
are bent forward; flexed and stiffened arms are held away from the body; fingers
are extended; and knees and hips are stiffly bent.
Steppage gait – results from footdrop caused by weakness or paralysis of the
pretibial and peroneal muscles, usually from lower motor neuron lesions. Footdrop
causes the foot to hang with the toes pointing down, causing the toes to scrape the
ground during ambulation.
Waddling gait – is a distinctive duck-like walk and usually a sign of muscular
dystrophy, spinal muscle atrophy or developmental dysplasia of the hip.
