简要总结
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).

研究组 & 干预措施
PBM + physiotherapy exercises
will be submitted to active PBM and physiotherapeutic exercises.
For irradiation, the individuals will be positioned comfortably in lateral decubitus on the examining table. Three points will be irradiated at the lesion level with a wavelength of 808 nm, 25 J per point for 12 sessions. The same laser device (Laser DMC Therapy EC).
Physical therapy will occur twice per week after PBM for six weeks. Static balance exercises will be performed with the feet together and tandem on a variety of different surfaces (hard surface, foam rubber and carpets with different textures) and sensory inputs (eyes open and closed). Dynamic balance exercises will involve walking forward and backward on firm and foam surfaces and circumventing obstacles. Muscle strengthening exercises, squatting and changing postural positions will also be performed. All activities will be in the form of play to maintain the children's interest
干预措施: Low level laser therapy (Device)
SHAM PBM + physiotherapy exercises
will be submitted to sham PBM and physiotherapeutic exercises.
For irradiation sham, the individuals will be positioned comfortably in lateral decubitus on the examining table. The same laser device (Laser DMC Therapy EC) will be used but the device will emit sound but not light.

结局指标
主要结局
Assessment of muscle activity
时间窗: 10 minutes
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
Sensory evaluation - monofilaments
时间窗: 10 minutes
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.
