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).

Primary | Assessment of muscle activity | Electromyography (EMG) will be performed with the EMG System®. The participants will be placed on an examining table and the skin will be cleaned with tissues soaked in alcohol for the placement of the markers. Disposable self-adhesive Ag/AgCl surface electrodes (Noraxon) measuring 10 mm in diameter will be attached to the belly of the lateral gastrocnemius, tibialis anterior and rectus femoris muscles on both lower limbs to capture the EMG signals. A reference electrode will be placed on the left wrist of the volunteers to impede interference of external noise | 10 minutes | |
Primary | Sensory evaluation - monofilaments | The sensory evaluation will be performed using the Semmes-Weinstein kit (Smiles®), which is a set of six nylon monofilaments of the same length that exert force on the specific area tested. Each monofilament has a different color and diameter: green (0.05 g), blue (0.2 g), violet (2 g), red (4 g), orang (10 g) and magenta (300 g). The score ranges from seven (green monofilament) to 1 (magenta monofilament). The test will be performed on the following dermatomes: L1, L2, L4, L5, S1, S2 and S3. | 10 minutes | |
Secondary | Evaluation of balance | Balance will be evaluated using the Pediatric Balance Scale, which consists of 14 items scored from 0 to 4 points. The maximum score is 56, with higher scores denoting better balance. | 10 minutos | |
Secondary | Analysis expression of brain-derived neurotrophic factor (BDNF) | BDNF be quantified in saliva samples from the participants using ELISA MAX HUMAN kits (BioLegend), which contain capture and detection antibodies for the precise quantification of each cytokine. All kits will be used following the manufacturer's instructions. The optical density of the samples will be measured in a spectrophotometer at 450 nm. Collection of saliva |

Secondary | Analysis expression Interleukin-10 (IL-10) | IL-10 will be quantified in saliva samples from the participants using ELISA MAX HUMAN kits (BioLegend), which contain capture and detection antibodies for the precise quantification of each cytokine. All kits will be used following the manufacturer's instructions. The optical density of the samples will be measured in a spectrophotometer at 450 nm. | 10 minutes |
