内在足部肌肉无力是老年人平衡不足的重要原因,由于害怕跌倒而导致运动范围有限,从而降低了生活质量。通过经皮电刺激(TENS)加强肌肉是一种有效的干预措施;然而,它对老年人的影响很少报道。本研究旨在研究TENS对舟骨高度的影响,balance,害怕跌倒。
在这项研究中,纳入48名年龄在65~75岁之间的参与者,并随机分为两组:TENS组和对照组.训练前后4周,舟骨高度,balance,对跌倒的恐惧被测量。
经过4周的训练,两组的舟骨高度均显著增加(p<0.05);TENS组的增幅更高(p=0.035)。TENS组在所有四个方向的平衡都有了更好的改善-前面,回来,左,右(p<0.05)。然而,对照组仅在三个方向观察到姿势平衡改善-正面,回来,和左(p<0.05)-两组之间无任何显着差异。此外,TENS组在训练4周后,对跌倒的恐惧程度降低(p=0.039)。
总之,这项研究的结果可以用作通过ES增强肌肉的一部分,以降低老年人跌倒或跌倒的风险。
Intrinsic foot muscle weakness is a crucial cause of balance deficit in the elderly, which leads to a limited range of motion from the fear of falling and subsequently decreases the quality of life. Muscle strengthening via transcutaneous electrical stimulation (TENS) is an effective intervention; however, its effects on elderly people have rarely been reported. This study was conducted to investigate the effects of TENS on
navicular height, balance, and fear of falling.
In this study, forty-eight participants aged 65-75 years were included and were randomly divided into two groups: the TENS and control groups. Before and after 4 weeks of training,
navicular height, balance, and fear of falling were measured.
After 4 weeks of training,
navicular height significantly increased in both groups (p < 0.05); however, the increase was higher in the TENS group (p = 0.035). The TENS group had a better improvement in balance in all four directions-front, back, left, and right (p < 0.05). However, postural balance improvements in the control group were observed in three directions only-front, back, and left (p < 0.05)-without any significant difference between the two groups. Furthermore, the TENS group decreased the scale of fear of falling after 4 weeks of training (p = 0.039).
In summary, the results of this study can be used as part of the muscle strengthening via ES for decreasing the risk of falls or fear of falling in the elderly.
