Brief Summary

We are going to investigate leprosy patients with neuropathies. This problem can lead to changes in nerve function and lead to disability. We will investigate a protocol with LLLT to improve pain, inflammation, and to prevent disabilities. We will test two groups, which will be divided into control and LLLT treated patients. In this groups we will perform quantitative measurements of the following parameters before and after the protocol application: electroneuromyography and muscle strength measurements, evaluation of activity limitation and risk awareness, evaluation of tactile sensitivity and evaluation of temperatures of hands and feet. Averages for all parameters will be compared before and after treatment (12 application sessions). We believe that LLLT can become an important alternative treatment to improve conduction velocity, tactile sensitivity, temperatures of hands and feet, muscle strength and pain, which will prevent nerve damage and disabilities

Outcome Measures

Primary Outcomes (1)

  • Change from Baseline Conduction Velocity at 28 days after LLLT.

    Will be performed on the MEB4200K, the active recording electrode is placed on the center o the muscle belly, and the reference electrode is placed distally, over the muscle tendon. Below is a description of the technique employed in each of these nerves: Ulnar Motor Nerve: Normal values: Amplitude≥ 3.80mv, conduction velocity ≥ 50m/s, distal latency ≤ 3.1 m/s. Delta conduction velocity (difference between the distal segment and the elbow segment)≥10m/s; (b)Common Peroneal Motor Study: Normal values: Amplitude ≥ 2.80 mv, conduction velocity ≥ 40m/s, distal latency(handle)≤ 5.0 msec. Delta conduction velocity (difference between the distal segment and the peroneal head segment)≥10m/s.

    Patients will be assessed one day before the first day of LLLT application and after 28 days of LLLT application.

Secondary Outcomes (5)

  • Change from Baseline Muscle Strength at 28 days after LLLT.

    Patients will be assessed one day before the first day of LLLT application and after 28 days of LLLT application.

  • Change from Baseline Tactile Sensitivity at 28 days after LLLT.

    Patients will be assessed one day before the first day of LLLT application and after 28 days of LLLT application.

  • Change from Baseline Pain intensity at 28 days after LLLT.

    Patients will be assessed one day before the first day of LLLT application and after 28 days of LLLT application.

  • Change from Baseline Tissue temperature variations of the body surface at 28 days after LLLT

    Patients will be assessed one day before the first day of LLLT application and after 28 days of LLLT application.

  • Change from Screening of Activity Limitation and Safety Awareness Scale at 28 days after LLLT.

    Patients will be assessed one day before the first day of LLLT application and after 28 days of LLLT application.

Study Arms (2)

Control

SHAM COMPARATOR

Leprosy patients with focal demyelinating neuropathy in compression sites of the ulnar and common peroneal nerves who will receive application "sham LLLT". The laser will be turned off, but the procedure will be the same as with the Low Level Laser Therapy (LLLT) group

Device: Sham LLLT

Low Level Laser Therapy

EXPERIMENTAL

Leprosy patients with focal demyelinating neuropathy in compression sites of the ulnar and common peroneal nerves who will receive intervention with low-intensity laser therapy (LLLT).

Device: LLLT

Interventions

LLLTDEVICE

The LLLT will be applied using a diode laser device (Recover Laser MMOptics, São Carlos/SP- Brazil) with parameters: 808nm, continuous output, 100mW, 8J. Laser probe will be applied directly and perpendicularly in skin contact (5 points), the time of irradiation will be 80 seconds per point, and treatments will be applied for three times a week for 12 sessions.

Low Level Laser Therapy
Sham LLLTDEVICE

That group receive application "sham LLLT". The laser will be turned off, but the procedure will be the same as with the LLLT group

Model Details: We will analyze leprosy patients with neuropathy. These patients will be randomly divided in: (a) Control: who will receive simulated application "sham" of LLLT; and (b) LLLT: who will receive LLLT (830 nm, continuous emission, 100mW output power and 3J power density). Treatments will occur in 12 sessions (3 times per week) on the nerves: a)ulnar: around the ulnar nerve at the elbow region, and b)common peroneal: surrounding fibular head. For the inclusion criteria will be selected leprosy patients (tuberculoid and borderline tuberculoid forms) with focal demyelinating neuropathy of the ulnar and common peroneal nerves by electroneuromyography (ENMG); patients without leprosy reactions and corticoid use. We will perform measurements of the following parameters before and after the LLLT protocol application: ENMG Muscle Strength; Tactile Sensitivity measured; Pain Intensity; Incapacity grade; Infrared thermography; Screening of Activity Limitation and Safety Awareness scale.
