The impact of the pandemic on physical and functional disabilities in children and adolescents with spina bifida.

STUDY DESIGN: Retrospective and cross-sectional study. OBJECTIVES: The study aimed to carry out telemonitoring to identify the impact of the pandemic on physical and functional disabilities in children and adolescents with SB, as reported by their caregivers, and to investigate adherence to a teleservice. SETTING: Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP). METHODS: Retrospective and cross-sectional study. Fifty-three patients with SB (mean age 12.0 (4.0) years; 23 males) participated in the telemonitoring. A questionnaire - 'Health management, health conditions, rehabilitation, interest in teleservice, and the well-being of the main caregiver' - investigated the clinical impact of the coronavirus pandemic. Only three caregivers participated in the teleservice (video call). RESULTS: According to telemonitoring, 62% of the patients discontinued physiotherapy sessions, and 69% reported needing adjustments in locomotion devices. The main complaints were muscle weakness and pain. CONCLUSION: We monitored general health and identified demands related to physical rehabilitation using telemonitoring in 42.4% of children and adolescents with SB monitored at the HCFMRP-USP. Telemonitoring and teleservice may be methods used for monitoring health conditions in patients with SB.

Can neuromuscular differences manifest by early adolescence in males between predominantly endurance and strength sports?

INTRODUCTION: Although neuromuscular function varies significantly between strength and endurance-trained adult athletes, it has yet to be ascertained whether such differences manifest by early adolescence. The aim of the present study was to compare knee extensor neuromuscular characteristics between adolescent athletes who are representative of strength (wrestling) or endurance (triathlon) sports. METHODS: Twenty-three triathletes (TRI), 12 wrestlers (WRE) and 12 untrained (CON) male adolescents aged 13 to 15 years participated in the present study. Maximal voluntary isometric contraction (MVIC) knee extensor (KE) torque was measured, and 100-Hz magnetic doublets were delivered to the femoral nerve during and after KE MVIC to quantify the voluntary activation level (%VA). The doublet peak torque (T100Hz) and normalized vastus lateralis (VL) and rectus femoris (RF) EMG (EMG/M-wave) activities were quantified. VL and RF muscle architecture was also assessed at rest using ultrasound. RESULTS: Absolute and relative (to body mass) KE MVIC torques were significantly higher in WRE than TRI and CON (p < 0.05), but comparable between TRI and CON. No significant differences were observed between groups for %VA, T100Hz or either VL or RF muscle thickness. However, VL EMG/M-wave was higher, RF fascicle length longer, and pennation angle smaller in WRE than TRI and CON (all p < 0.05). CONCLUSION: The wrestlers were stronger than triathletes and controls, potentially as a result of muscle architectural differences and a greater neural activation. Neuromuscular differences can already be detected by early adolescence in males between predominantly endurance and strength sports, which may result from selection bias and/or physical training.
