Thoracic hyperkyphosis, one of the most common spinal deformities, may lead to undesirable pulmonary outcomes.
To study, the efficacy of virtual reality exercise training on thoracic hyperkyphosis and respiratory parameters in young women.
Randomized clinical trial.
Laboratory setting.
Participants were randomly assigned to one of two 4-week exercise training groups: regular training (RT), which involved stretch and strength training, or virtual reality with RT (VRRT), which involved dance training with the Xbox 360 Kinect® game in addition to the exercises, which the RT group received.
The authors measured kyphosis angle with a Flexicurve ruler and recorded respiratory parameters (forced vital capacity [FVC] and forced expiratory volume in 1 s [FEV1]) with a spirometer in each participant at baseline and postintervention. Separate 2 × 2 repeated-measure analysis of variances were used to analyze differences between means for kyphosis angle, FEV1, and FVC. Based on the significant interactions between time and group, the paired t test was used to compare the results at baseline and postintervention, and the independent sample t test was used to compare the differences in changes between groups. Level of significance was considered at P < .05 except for paired t test that was adjusted to P < .025 for each variable in 2 groups.
The results showed statistically significant interactions between time and group for kyphosis angle, FEV1, and FVC. Postintervention thoracic kyphosis angle decreased and FVC increased significantly in both groups and FEV1 improved significantly in virtual reality with RT group. The improvements in thoracic kyphosis, FVC, and FEV1 in the virtual reality with RT group were significantly greater (P < .001) than in the RT group.
Dance training with the Xbox 360 Kinect game was an effective therapy in improving thoracic kyphosis angle, FVC, and FEV1 in young women with thoracic hyperkyphosis.
胸椎后凸是最常见的脊柱畸形之一，可能导致不良的肺部后果。
研究虚拟现实运动训练对年轻女性胸椎后凸和呼吸参数的疗效。
随机临床试验。
实验室环境。
参与者被随机分配到两个为期4周的运动训练组之一：常规训练（RT）组，包括伸展和力量训练；虚拟现实与常规训练结合组（VRRT），除了接受RT组的训练外，还包括使用Xbox 360 Kinect®游戏进行舞蹈训练。
作者在基线和干预后，使用Flexicurve尺测量每位参与者的后凸角，并用肺活量计记录呼吸参数（用力肺活量[FVC]和1秒用力呼气量[FEV1]）。采用单独的2×2重复测量方差分析来分析后凸角、FEV1和FVC均值之间的差异。基于时间和组间的显著交互作用，采用配对t检验比较基线和干预后的结果，采用独立样本t检验比较组间变化的差异。除配对t检验外，显著性水平设定为P <.05，配对t检验针对两组中的每个变量调整为P <.025。
结果显示，后凸角、FEV1和FVC在时间和组间存在统计学显著交互作用。干预后，两组的胸椎后凸角均显著减小，FVC显著增加，虚拟现实与常规训练结合组的FEV1显著改善。虚拟现实与常规训练结合组在胸椎后凸、FVC和FEV1方面的改善显著大于RT组（P <.001）。
使用Xbox 360 Kinect游戏进行舞蹈训练是改善年轻女性胸椎后凸患者胸椎后凸角、FVC和FEV1的有效疗法。
