Summary

Myelomeningocele is a neural tube defect that occurs between the third and fourth week of gestation. Functional impairment occurs due to dysplasia of the nerve roots, which can lead to flaccid paralysis and sensory-motor dysfunction below the level of the lesion. Although advances in the multidisciplinary treatment of myelomeningocele have led to functional improvements in affected children, novel therapeutic modalities, such as photobiomodulation (PBM), could be a promising complement to treatment. Objective: Evaluate the effectiveness of PBM combined with physiotherapeutic exercises on the sensory-motor response in individuals with myelomeningocele at the lower lumbar and sacral level. Participants will be recruited from the Integrated Health Clinic of University Nove de Julho and randomized into two groups: Grupo 1 - treatment with PBM at a wavelength of 808 nm + physical therapy; Grupo 2 - sham PBM + physical therapy. Evaluations will involve electromyography of the gastrocnemius, tibialis anterior and rectus femoris muscles of both lower limbs. Balance will be evaluated using the Pediatric Balance Scale. The sensory evaluation will be performed using the Semmes-Weinstein monofilament kit (Smiles®). BDNF levels will be determined using ELISA. The data will be analyzed with the aid of GraphPad PRISM version 7.0. The Kolmogorov-Smirnov test will be used to determine the normality of the data. Variables that fit the Gaussian curve will be expressed as mean and standard deviation values. The t-test will be used for the comparisons between groups, with the level of significance set to 95% (p \< 0.05).

Conditions

  • Myelomeningocele Without Hydrocephalus
  • Sensory Defect
  • Motor Activity

Interventions

DEVICE

Low level laser therapy

For the PBM protocol, articles of interest were identified through analyses of titles and abstracts. Articles addressing PBM in experimental models or clinical trials of spinal cord injuries were included and articles not pertinent to the proposed study were excluded. Next, the selected articles were analyzed and used for the creation of an initial protocol (Table 1). For irradiation, the individuals will be positioned comfortably in lateral decubitus on the examining table. Three points will be irradiated above the lesion level, which will be located using an imaging exam brought by the guardian on the day of the evaluation. After determining the lesion level, palpation of the transverse processes of the vertebrae will be performed. The same laser device (Laser DMC Therapy EC) will be used for both groups. For the placebo group, the device will emit sound but not light.
