The objective of this research was to analyze the functional changes of lower limbs by means of surface electromyography in patients with acquired immunodeficiency syndrome.
A total of 60 men and women (age mean of 36.77 ± 9.33 years) were divided into two groups: 30 individuals with human immunodeficiency virus group (HIVG) Subtype 1 and 30 healthy individuals control group. Muscle activity was evaluated using surface electromyography (sEMG). sEMG measurements were made while the subjects assumed the static positions: Rest in orthostatism (RS), squat "normalization factor," right and left single leg support (RSLS, LSLS) and during functional activities: Right and left single leg step rise (RSLSR, LSLSR), right and left single leg step down (RSLSD, LSLSD), rising and seating on a chair (RC, SC).
To sEMG results revealed statistically significant values in the conditions of RSLS to left semitendinosus muscle, for LSLS to right and left semitendinosus, right rectus femoris and right gluteus medius muscles, for LSLSR to right rectus femoris and right tensor fasciae latae muscles, for RSLSD to right and left semitendinosus and right rectus femoris muscles, for RC to right rectus femoris and left gluteus medius muscles and for SC to right semitendinosus, right rectus femoris and right and left gluteus medius muscles.
It can be concluded that individuals with acquired immunodeficiency syndrome presented changes in lower limb muscle activity.
本研究的目的是通过表面肌电图分析获得性免疫缺陷综合征患者下肢的功能变化。
总共60名男性和女性（平均年龄36.77±9.33岁）被分为两组：30名1型人类免疫缺陷病毒组（HIVG）个体和30名健康个体作为对照组。使用表面肌电图（sEMG）评估肌肉活动。在受试者处于静态姿势时进行sEMG测量：直立位休息（RS）、深蹲“归一化因子”、左右单腿支撑（RSLS、LSLS），以及在功能活动期间：左右单腿上台阶（RSLSR、LSLSR）、左右单腿下台阶（RSLSD、LSLSD）、从椅子上起身和坐下（RC、SC）。
sEMG结果显示，在RSLS时左侧半腱肌、LSLS时右侧和左侧半腱肌、右侧股直肌和右侧臀中肌、LSLSR时右侧股直肌和右侧阔筋膜张肌、RSLSD时右侧和左侧半腱肌及右侧股直肌、RC时右侧股直肌和左侧臀中肌、SC时右侧半腱肌、右侧股直肌以及右侧和左侧臀中肌的情况下，具有统计学显著差异。
可以得出结论，获得性免疫缺陷综合征患者下肢肌肉活动存在变化。
