PHYSICAL THERAPY IMPLICATIONS
Examination and Evaluation
Monitor and report signs of neuroleptic malignant syndrome, including hyperthermia, diaphoresis, generalized muscle rigidity, altered mental status, tachycardia, changes in blood pressure (BP), and incontinence. Symptoms typically occur within 4–14 days after initiation of drug therapy, but can occur at any time during drug use.
Be alert for new seizures or increased seizure activity, especially at the onset of drug treatment. Document the number, duration, and severity of seizures, and report these findings to the physician immediately.
Assess motor function, and be alert for extrapyramidal symptoms. Report these symptoms immediately, especially tardive dyskinesia, because this problem may be irreversible. Common extrapyramidal symptoms include:
∘ Tardive dyskinesia (uncontrolled rhythmic movement of mouth, face, and extremities, lip smacking or puckering, puffing of cheeks, uncontrolled chewing, rapid or worm-like movements of tongue).
∘ Pseudoparkinsonism (shuffling gait, rigidity, tremor, pill-rolling motion, loss of balance control, difficulty speaking or swallowing, masklike face).
∘ Akathisia (restlessness or desire to keep moving).
∘ Other dystonias and dyskinesias (dystonic muscle spasms, twisting motions, twitching, inability to move eyes, weakness of arms or legs).
Assess heart rate, ECG, and heart sounds, especially during exercise (See Appendices G, H). Report a rapid heart rate (tachycardia) or signs of other arrhythmias, including palpitations, chest pain, shortness of breath, fainting, and fatigue/weakness.
Assess BP when patient assumes a more upright position (lying to standing, sitting to standing, lying to sitting). Document orthostatic hypotension and contact physician when systolic BP falls >20 mm Hg or diastolic BP falls >10 mm Hg.
Report any troublesome respiratory problems, including severe or prolonged cough, nasopharyngeal irritation, or difficult/labored breathing.
Be alert for signs of hyperglycemia, including confusion, drowsiness, flushed/dry ...
