Handball affects the spinal anterior-posterior curvatures and disturbs the foot plantar pressure which provides insights into alterations in an individual's posture. However, little is known about how the mal-alignment affects the distribution of plantar pressure.
To investigate the relationship between the thoracic kyphosis angle, and plantar pressure distribution among handball players.
Sixty male handball players were distributed into two groups based on their thoracic kyphosis angles. Group A: 28 handball players with an angle greater than 44 (kyphotic group), and group B: 32 handball players with an angle equal to or less than 44 (normal group). The Formetric III 4D spine and DIERS Pedoscan devices were used to measure the trunk anthropometry and plantar pressure distribution. The Pearson correlation test was used to explore the relationship between the kyphosis angle and plantar pressure distribution.
Group A was significantly taller, had longer trunk length, greater lumbar lordosis angles, and forefoot plantar pressure (FPP), and less rearfoot plantar pressure (RPP) than group B ( ). They showed a highly significant positive correlation between the thoracic kyphosis angle and FPP, and a highly significant negative correlation with the RPP ( , , respectively). There was no correlation between the lumbar lordosis angle and FPP or RPP ( , , respectively).
Handball players with greater thoracic kyphosis angle have greater lumbar lordosis angle. Increasing the thoracic kyphosis angle is strongly associated with increased FPP and decreased RPP. While there is no relationship between the lumbar lordosis angle and FPP or RPP.
手球运动影响脊柱的前后曲度，并干扰足底压力，这为了解个体姿势的变化提供了线索。然而，对于脊柱排列不齐如何影响足底压力分布知之甚少。
探讨手球运动员胸椎后凸角与足底压力分布之间的关系。
60名男性手球运动员根据其胸椎后凸角分为两组。A组：28名后凸角大于44°的手球运动员（后凸组），B组：32名后凸角等于或小于44°的手球运动员（正常组）。使用Formetric III 4D脊柱测量仪和DIERS Pedoscan设备测量躯干人体测量学指标和足底压力分布。采用Pearson相关检验探讨后凸角与足底压力分布之间的关系。
A组比B组显著更高，躯干长度更长，腰椎前凸角更大，前足足底压力（FPP）更大，而后足足底压力（RPP）更小（ ）。他们显示胸椎后凸角与FPP之间存在高度显著的正相关，与RPP之间存在高度显著的负相关（分别为 ， ）。腰椎前凸角与FPP或RPP之间无相关性（分别为 ， ）。
胸椎后凸角较大的手球运动员腰椎前凸角也较大。胸椎后凸角增加与FPP增加和RPP降低密切相关。而腰椎前凸角与FPP或RPP之间没有关系。
