Hyperbaric Oxygen Therapy Versus High Power Laser for Diabetic Neuropathy (HBOT-HPLT-DPN)

25 september 2026 bijgewerkt door: Mostafa Mahmoud Mohamed Youssef Khalifa, Cairo University

Hyperbaric Oxygen Therapy Versus High Power Laser Therapy On Sensorimotor Functions In Patients With Diabetic Peripheral Neuropathy

The purpose of this study is to compare the clinical effects of Hyperbaric Oxygen Therapy (HBOT) versus High-Intensity Laser Therapy (HPLT) on sensorimotor functions and nerve conduction in patients suffering from painful diabetic peripheral neuropathy.

Participants are divided into three equal groups. The first group receives a traditional physiotherapy program focused on ankle and foot exercises. The second group receives hyperbaric oxygen therapy sessions in addition to the traditional program. The third group receives high-power MLS laser therapy alongside the traditional program. Investigators look at whether either advanced intervention shows superiority in improving nerve functionality and reducing neuropathic pain.

Gedetailleerde beschrijving

Diabetic peripheral neuropathy (DPN) is a major microvascular complication of diabetes leading to progressive nerve damage and neuropathic pain. This randomized controlled trial evaluates and compares the efficacy of two non-pharmacological interventions: Hyperbaric Oxygen Therapy (HBOT) and High-Intensity Laser Therapy (HPLT).

A total of 66 medically controlled patients with painful diabetic neuropathy are randomly assigned into three equal parallel groups (22 patients per group):

  • Control Group (A): Receives a traditional physiotherapy program including foot and ankle ROM exercises, strengthening, and functional walking training for 5 sessions per week for 3 weeks.
  • Study Group (B): Receives Hyperbaric Oxygen Therapy (100% oxygen at 2.5 ATA for 60 minutes, totaling 90 minutes per session) for 15 sessions over 3 weeks, combined with the traditional physiotherapy program.
  • Study Group (C): Receives High-Power Laser Therapy using a Multiwave Locked System (MLS) laser device (1500 Hz frequency) applied every other day for 9 sessions over 3 weeks, combined with the traditional physiotherapy program.

Assessments are conducted before and after the 3-week treatment period using objective Nerve Conduction Studies (NCS) for the sural and common peroneal nerves, and subjective screening via the Arabic Michigan Neuropathy Screening Instrument (MNSI) score.

Tijdsspanne
Change in Michigan Neuropathy Screening Instrument (MNSI) score
Tijdsspanne: Baseline and 3 weeks post-treatment

The Michigan Neuropathy Screening Instrument (MNSI) questionnaire was used to assess symptoms of diabetic peripheral neuropathy. Abnormal responses were summed to obtain the total score. The questionnaire score ranges from 0 to 13, with higher scores indicating greater neuropathic symptom burden.
