■轮椅使用者在姿势转移和运动时采用的自步法可能需要上肢足够的速度强度。在临床实践中,我们观察到有限的功能独立性和社会参与。
■这项研究旨在调查和比较患有脊柱裂(SB)的轮椅使用者与典型的青少年之间的速度-力量关系。特别是,分析SB轮椅使用者在肩肘等速评估中是否达到预设速度。
■横断面观察性研究。
■圣保罗大学RibeirãoPreto医学院。
■SB(SB;n=11)和对照组(CT;n=22)进行了肩展肌(SAB)的等速评估,内征子(SAD),屈肌(SFL),延伸符(SEX),和肘屈肌(EFL)和伸肌(EEX)在60和120度的速度。s-1.协方差分析用于确定肌肉性能的组间差异。
■峰值扭矩(PT)的值,功率(Pow),达到峰值扭矩的时间(tPT)和达到等速速度的百分比。
■达到120度的百分比。两组s-1为中低(26-75.9%)。CT显示达到预设速度的相对风险明显高于SB。SB在60度时为SAB和SFL提供了更高的PT和Pow。s-1,120度时SFL和EEX的PT更高。s-1,SFL在120度时降低tPT。s-1与CT比较。
■SB很难达到120度。s-1,可能与神经肌肉差异有关。然而,他们在日常任务中的手臂运动似乎保持产生PT和Pow的能力。
UNASSIGNED: The self-paced adopted by wheelchair users in their postural transfers and locomotion may require sufficient levels of speed-strength in the upper limbs. In clinical practice, we observed limited functional independence and social participation.
UNASSIGNED: This study aimed to investigate and compare the speed-strength relationship between wheelchair users with spina bifida (SB) and typically developing youth. In particular, to analyze if SB wheelchair users reached the preset velocities in the
isokinetic evaluation of shoulder and elbow.
UNASSIGNED: Cross-sectional observational study.
UNASSIGNED: Ribeirão Preto Medical School of the University of São Paulo.
UNASSIGNED: SB (SB; n = 11) and controls (CT; n = 22) performed the
isokinetic assessment of shoulder abductors (SAB), adductors (SAD), flexors (SFL), extensors (SEX), and elbow flexors (EFL) and extensors (EEX) at velocities of 60 and 120degree.s-1. The analysis of covariance was used to identify the intergroup differences in muscle performance.
UNASSIGNED: The values of peak torque (PT), power (Pow), time to peak torque (tPT) and the percentage to reach the
isokinetic velocity.
UNASSIGNED: The percentage to reach 120degree.s-1 was moderate-to-low for both groups (26-75.9%). CT presented a significantly greater relative risk of reaching the preset velocities than SB. SB presented higher PT and Pow for SAB and SFL at 60degree.s-1, higher PT for SFL and EEX at 120degree.s-1, and lower tPT for SFL at 120degree.s-1 compared to CT.
UNASSIGNED: SB had difficulty reaching 120degree.s-1, probably related to neuromuscular differences. However, arm movements in their daily tasks seem to maintain the ability to produce PT and Pow.
