Conditions
Brief summary
Purposes of this study were the following: 1. To evaluate the therapeutic efficacy of NMES in improving the motor conduction velocity (MCV) of the neuropathic common peroneal nerve post burn. 2. To evaluate the therapeutic efficacy of LIL in improving the motor conduction velocity (MCV) of the neuropathic common peroneal nerve post burn. 3. To detect which one of both was the better and most effective than the other in improving the motor conduction velocity (MCV) of the neuropathic common peroneal nerve post burn.
Detailed description
Burned patients experience various problems, including skin damage, vascular damage, and metabolic stress. These injuries can lead to peripheral neuropathies, which can affect nerve function and cause weakness or lack of sensation. Lymphatic damage can delay wound healing, causing contractures that affect the patient's physical function. Burn-Associated polyneuropathy (BAPN) is common after thermal injury, affecting nerve function. Electrophysiological assessments of muscle and nerves are essential in neurology, physical therapy, and related clinical disciplines. Neuromuscular electrical stimulation (NMES) is used to increase force output, strengthen muscles, and control pain. Low-intensity laser therapy (LILT) is used to treat chronic inflammatory and fibrotic conditions, improving absorption of fluid, secretion of macrophage growth factors, DNA synthesis, pain reduction, and electron respiratory chain reaction. However, the effect of LILT on scar formation and treatment of fibrosis or calcification secondary to hematomas or fat necrosis is not yet evaluated. The need for this study developed from the lack of quantitative knowledge and information in the published studies about the application of both NMES and LIL to improve the neuropathic common peroneal nerve postburn. The significance of this study arises from the rarity of information about the effectiveness of both NMES and LIL on the neuropathic common peroneal nerve post-burn, as well as the precise dosage and frequency of treatment required to promote improvement of the neuropathic common peroneal nerve post burn.
Interventions
DEVICENeuromuscular electrical stimulation (NMES)
NMES unit manufactured by Enraf-Holland was be used to administer the neuromuscular electrical stimulation (NMES) The study involved adjusting the patient's hips, knees, and ankles to achieve a comfortable position. Two electrodes of NMES were used in the first study group and a placebo in the control group. The electrodes were placed on the popliteal fossa and fibular head, and each session was conducted for 15 minutes daily for 2 months.
DEVICElow-intensity laser therapy (LILT)
The laser unit is a small, hand-held, class III laser product manufactured by Laserex Technology Pty Ltd Australia. It offers continuous and pulsed laser therapy, with continuous therapy being the most effective. The device has a maximum average power of 5 milliwatts, a wavelength of 820 nm, and a power density of 0.39 W/cm2. Patients were treated as outpatients, receiving full explanations about the purpose, therapeutic, and physiological benefits of low-intensity laser therapy (LILT). They were relaxed in supine position, with hips and knees adjusted. The patient was irradiated in a continuous mode and direct contact method, 3 times per week for 2 months, at 1-cm intervals and across the surface in grids. The laser applicator was applied to the surface, maintaining contact for maximum penetration.

| motor conduction velocity (MCV) | at base line and following 8 weeks | The study involved a common peroneal nerve MCV measurement in an air-conditioned room. The subject was placed in a supine position for 5 minutes to rest and relax. The recording electrodes were placed over the EDB muscle, with the active electrode placed over the main bulk of the muscle. The stimulating electrodes were placed 8 cm proximal to the active electrode for distal latency and distally in the lateral part of the popliteal fossa for proximal latency. The subject was then asked to lie supine for 5 minutes for leg massage, rest, and relaxation. The EMG12 program disk was loaded, and electrodes were connected to the active channels and common electrode. The program was moved to the ready condition after pressing keys on the keyboard. The sensitivity was 1 mv/diameter, the sweep speed was 3 ms, and the stimulus intensity ranged from 0.1 to 99 mA. Segmental distances between stimulation points were measured using a tape measure. |
