Patient-handling activities predispose women to chronic low back pain (CLBP), but sufficient evidence is not available on whether a 3D moving platform, made for core stability exercise, affects pain, trunk flexibility, and static/dynamic muscle contractions in CLBP patients. The participants were twenty-nine women who were randomly divided into a control group (CON) and a 3D exercise group (3DEG), which took part in 3D moving exercise three times a week for 8 weeks. Both groups measured a visual analog scale (VAS) about their CLBP. Body composition, forward and backward trunk flexibilities, static muscle contraction property in rectus abdominis, and erector spinae were measured by tensiomyography, which found contraction time (Tc) and maximal displacement (Dm). Dynamic muscle contraction property in the abdomen and back were measured with an isokinetic device, which could measure peak torque (Pt) and work per repetition (Wr), before and after the trial. The 3DEG had a significantly decreased fat mass and waist/hip ratio, as well as improved static muscle contractions of the erector spinae. The Wr of trunk extensor of 3D exercise group were also significantly increased. In the VAS, although the scores showed a significant change in some variables, while others did not. The Δ% in feeling pain at rest or at night, during exercise, walking, sitting in a hard chair, sitting in a soft chair, and lying down in 3DEG were significantly changed after 8 weeks. This indicates that the platform exercise provided a greater reduction of pain for activities that are done on a daily basis. : This study confirms that the 3D moving platform exercise can provide the similar effect of the core stability exercise used in previous studies. Moreover, this study suggests that 3D moving platform exercise is a suitable means to reduce fatness, to increase trunk extensor, and to increase trunk backward flexibility, which led to reduced back pain in the women with CLBP.
患者处理活动使女性易患慢性下腰痛(CLBP),但目前尚无足够的证据表明用于核心稳定性锻炼的 3D 运动平台是否会影响 CLBP 患者的疼痛、躯干灵活性以及静态/动态肌肉收缩。参与者为 29 名女性,随机分为对照组(CON)和 3D 运动组(3DEG),两组均每周进行 3 次 3D 运动,持续 8 周。两组均使用视觉模拟量表(VAS)评估 CLBP。通过张力测量法测量身体成分、躯干前屈和后伸灵活性、腹直肌和竖脊肌的静态肌肉收缩特性,发现收缩时间(Tc)和最大位移(Dm)。使用等速装置测量腹部和背部的动态肌肉收缩特性,可测量峰值扭矩(Pt)和每重复工作(Wr),在试验前后进行测量。3DEG 的体脂和腰臀比显著降低,竖脊肌的静态肌肉收缩力得到改善。3D 运动组的躯干伸肌 Wr 也显著增加。在 VAS 中,虽然一些变量的评分显示出显著变化,但其他变量则没有。3DEG 在休息或夜间、运动时、行走时、坐在硬椅子上、坐在软椅子上以及躺下时感到疼痛的 Δ%显著改变,经过 8 周后。这表明平台运动为日常生活中进行的活动提供了更大的疼痛缓解。本研究证实,3D 运动平台运动可提供与以往研究中使用的核心稳定性运动相似的效果。此外,本研究表明,3D 运动平台运动是一种减少脂肪、增加躯干伸肌和增加躯干后伸灵活性的合适方法,从而减轻 CLBP 女性的腰痛。
