Applicability and tolerability of electrical stimulation applied to the upper and lower leg skin surface for cueing applications in Parkinsons disease

Due to possible sensory impairments in people with Parkinsons disease, several methodological aspects of electrical stimulation as a potential cueing method remain to be explored. This study aimed to investigate the applicability and tolerability of sensory and motor electrical stimulation in 10 people with Parkinsons disease. The study focused on assessing the electrical stimulation voltages and visual analogue scale discomfort scores at the electrical sensory, motor, discomfort, and pain thresholds. Results show that sensory electrical stimulation at the tibialis anterior, soleus, hamstrings, and quadriceps stimulation sites was applicable and tolerable for 6 10, 10 10, 9 10, and 10 10 participants, respectively. Furthermore, motor electrical stimulation at the tibialis anterior, soleus, hamstrings, and quadriceps stimulation sites were applicable and tolerable for 7 10, 7 10, 7 10, and 8 10 participants, respectively
