Knee

The kneeling position has frequently been associated with a higher prevalence of knee pathologies. People who adopt this position within their work and/or religious activities are more exposed to knee pathologies. In the tall keeling posture, the position of the feet can play an important role in the magnitude of the force and pressure supporting the knee. The objective of this investigation was to compare the magnitude of the ground reaction force, the distribution of the support area and the pressures associated with them, in the tall kneeling posture with two different positions of the feet, in order to identify the position in which less discomfort could be produced and to diminish the potential damage to this joint. A sample of 20 volunteers (age = 22.0±1.5 years; weight = 70.3±13.5 kg) was assessed. Pressure, the contact area, the centre of pressure and GRF, all within the contact surface between the knees and the floor, as well as the discomfort described by the volunteers were measured in two different ankle positions: plantar flexion (PF) and dorsiflexion (DF). In DF condition was observed: a higher frequency of a single pressure peak (p跪姿常与膝关节病变的高患病率相关。在工作或宗教活动中采取跪姿的人群，罹患膝关节病变的风险更高。在高跪姿状态下，足部姿态对膝关节所承受的力与压力大小具有重要影响。本研究旨在对比两种不同足部姿态下的高跪姿状态中，地面反作用力（ground reaction force, GRF）、支撑区域分布及其伴随的压力大小，以明确可减轻不适感、降低该关节潜在损伤的最优足部姿态。本研究纳入20名志愿者作为研究对象（年龄：22.0±1.5岁；体重：70.3±13.5 kg）。研究针对两种不同的踝关节姿态——跖屈（plantar flexion, PF）与背屈（dorsiflexion, DF），测量了膝部与地面接触区域内的压力、接触面积、压力中心以及地面反作用力，同时记录志愿者自述的不适感。在背屈姿态条件下，观察到单次压力峰的出现频率更高（p
