Surface electromyography (EMG) and kinematic measurements enable the objectivequantification of neuromuscular function and movement in patients suffering Parkinson?sdisease or another movement disorders. However, neuromuscular activity has never beencharacterized in animal models by using this useful technique. Instead of that,subcutaneous EMG recordings have commonly been used with the subsequentpathological and time limitation problems. In this work we describe the use ofsubcutaneous and surface electrodes to obtain recordings either from healthy rats as fromthose that were treated with 6-OHDA. Experimental studies in neurodegenerativedisorders require the implementation of different behavioral tests to verify and quantifythe illness progression. Our results demonstrate that the use of surface electrodes could bea feasible technique to characterize neuromuscular activity because of its reliability and itseasy implementation.
