Efficacy of Class IV LASER Therapy and Sensory Re-education in Patients with Diabetic Neuropathy: A Case Report

Abstract Diabetic neuropathy (DN) is a common complication of chronic diabetes mellitus, which is prevalent worldwide. We intend to measure the result of class IV LASER therapy (LT) and sensory re-education (SR) in improving sensory levels in patients with DN. The neurological physiotherapist assessed the nerve conduction velocity (NCV) of the tibial and peroneal nerves on the 50-year-old female patient, who had been diagnosed with DN by her primary care neurologist. Monofilament testing was conducted on 10 locations on the dorsal and plantar aspects of both feet. Following that, class IV LT was administered to the right leg and SR was applied to the left. After the treatment procedure, again monofilament testing was performed, and NCV was also carried out. Baseline data of monofilament testing was 8/10 points on the bilateral leg and post-intervention was 10/10 points on the right leg and 9/10 points on the left leg. Pre- and post-intervention changes in electrophysiological parameters of the tibial and peroneal nerve were recorded. This case report emphasizes the role of class IV LASER and SR in patients with DN and SR, which improve the sensory function of the lower limb. Class IV LT and SR provide an effective treatment protocol for treating symptoms in patients with DN as well as to regain sensation of lower limbs in patients with DN.
