Background

Despite studies showing that gait is affected in adolescent idiopathic scoliosis (AIS), it remains unclear whether gait oxygen consumption is altered.

Research Question

The aims of the present study were to compare energy consumption during gait between subjects with AIS and healthy controls, and to examine the effect of brace use on gait energy expenditure.

Methods

This prospectively designed study included 15 AIS and 15 healthy girls, whose ages ranged from 10 to 16 years old and Cobb angles from 20 and 45°. At the end of the first month of brace use for the first time in individuals with AIS, oxygen consumption was measured with and without brace use on a treadmill at a gait speed of 4 km.h⁻¹ using a metabolic analyzer.

Results

There was no statistically significant difference in gross and net gait oxygen consumption measurements between AIS and healthy individuals or between individuals with AIS with or without brace use (p > 0.05).

Significance

After one month of brace treatment, AIS is not associated with an additional metabolic load with or without the brace during gait when compared to healthy subjects.

青少年特发性脊柱侧弯的步态耗氧量和支架使用的效果。

背景

尽管研究表明步态在青少年特发性脊柱侧凸（AIS）中受到影响，但仍不清楚步态氧消耗是否改变。

研究问题

本研究的目的是比较具有AIS的受试者和健康对照者在步态中的能量消耗，并检查支架使用对步态能量消耗的影响。

方法

这项前瞻性设计研究包括15名AIS和15名健康女孩，其年龄范围为10至16岁，科布角为20至45°。在患有AIS的患者中，首次使用支具的第一个月末，使用代谢分析仪在跑步机上以4 km.h ^-1的步速测量有无使用支具的氧气消耗。

结果

在AIS与健康个体之间，或在使用或不使用括号的AIS个体之间，总步态和净步态耗氧量的测量值均无统计学显着性差异（p  > 0.05）。

意义

支架治疗一个月后，与健康受试者相比，AIS在步态过程中无论有无支架，都没有额外的代谢负荷。
