This Study Aims to Investigate the Efficacy of Photobiomodulation in the Treatment of Anti-MAG-induced Peripheral Neuropathy (LASER-MAG) (LASER-MAG)

The Efficacy of Photobiomodulation in the Treatment of Anti-MAG-Induced Peripheral Neuropathy: LASER-MAG Study.
Patients treated in the hematology department of the Quimper/Cornouaille Hospital Center for IgM monoclonal gammopathy with anti-MAG and symptomatic peripheral neuropathy often reach a therapeutic impasse.
The treatment of neuropathic pain is complex, but recently a new non-pharmacological therapy, photobiomodulation, has shown evidence of efficacy and improved quality of life in the treatment of these peripheral neuropathies.
This new therapy uses low-intensity lasers; it is non-invasive, athermic, and has no reported side effects. The general principle is to expose tissues to visible light in the red and near-infrared spectrum to elicit a biological response.
The study aims to evaluate the efficacy and tolerability of photobiomodulation in this population of patients with anti-MAG neuropathy.

patients with anti-MAG neuropathy due to IgM monoclonal gammopathy

Each patient receives 16 sessions of PBM over 6 weeks using the ATP38 device.
Both upper limbs are treated simultaneously for 12 minutes each.
The lower limbs are also treated for 12 minutes each.
Assessments of disability (ONLS, R-ODS), pain (NPSI), and quality of life (QLQ C30, QLQ CIPN20) are conducted weekly.
Neurological and hematological consultations are conducted before and after PBM sessions.
