Improved methods for electroacupuncture and electromyographic recordings in normal and parkinsonian rhesus monkeys

▶ Rhesus monkeys can be trained for procedures including electroacupuncture (EA) and eletromyography (EMG). ▶ Chronic EA did not produce adverse effects, rather it improved locomotor functions in MPTP-treated rhesus monkeys. ▶ EMG can be used to distinguish differences in muscle activity between the arms with and without MPTP-induced rigidity.
