Scapular winging (SW) is defined as increased prominence of the whole medial border of the scapula. Many researchers recently recommended knee push-up plus (KPP) for enhancing serratus anterior (SA) activation. However, during push-up plus, thoracic kyphosis (TK) may usually occur as a compensatory movement. Thus, the purpose of this study was to investigate the effect of Thera-Band application during KPP on rectus abdominis (RA) activity, TK angle (TKA), SA activity, and amount of SW in subjects with SW.Fifteen subjects performed KPP with Thera-Band applied to different posterior body parts (no Thera-Band, in the occiput, and in the thoracic region). Electromyography was used to record the RA and SA activities. Image J software was used to calculate the compensatory TKA during KPP, and a scapulometer was used to measure SW in the quadruped position. One-way repeated-measures analysis of variance was used to test for significance.KPP with Thera-Band in the occiput showed significantly lower RA activity (P = .001) and TKA (P < .001) than KPP with no Thera-Band. SA activity (P = .020, P = .047) and SW (P < .001, P < .001) were significantly lower with Thera-Band applied to the occiput and thoracic regions than in KPP with no Thera-Band.Thera-Band applied to the occiput and thorax can be beneficial as it decreases RA and SA muscle activity and reduces TKA and SW during KPP in subjects with SW.
肩胛翼状突出（SW）被定义为肩胛骨整个内侧缘的突出增加。最近许多研究人员推荐使用强化俯卧撑（KPP）来增强前锯肌（SA）的激活。然而，在做强化俯卧撑时，胸椎后凸（TK）通常可能作为一种代偿性动作出现。因此，本研究的目的是调查在KPP过程中应用弹力带对SW患者腹直肌（RA）活动、TK角度（TKA）、SA活动和SW程度的影响。15名受试者在弹力带应用于不同身体后部位置（不使用弹力带、应用于枕部、应用于胸部区域）的情况下进行KPP。使用肌电图记录RA和SA的活动。使用Image J软件计算KPP过程中的代偿性TKA，并使用肩胛测量仪测量四足位的SW。采用单因素重复测量方差分析来检验显著性。与不使用弹力带的KPP相比，弹力带应用于枕部的KPP显示RA活动（P = 0.001）和TKA（P < 0.001）显著降低。与不使用弹力带的KPP相比，弹力带应用于枕部和胸部区域时，SA活动（P = 0.020，P = 0.047）和SW（P < 0.001，P < 0.001）显著降低。弹力带应用于枕部和胸部可能有益，因为它可降低SW患者在KPP过程中的RA和SA肌肉活动，并减少TKA和SW。
