Effect of a dynamic seat pan design on spine biomechanics, calf circumference and perceived pain during prolonged sitting

Could Horse Gait and Induced Pelvic Dynamic Loads in Female Equestrians Be a Risk Factor in Pudendal Neuralgia?

“…Together with the saddle’s shape and the rider’s weight, the horse’s movement affects the distribution of interfacial pressure, which can lead to undesirable effects such as tissue compression and shearing, or traumatic micro-shock of the rider’s perineal area. Classical seating surfaces ( Figure 1 a) display limited curvatures, and have been the subject of a number of studies [ 16 , 17 , 18 , 19 ]. Conversely, the saddle of a horse has a complex geometry ( Figure 1 b), with a hyperbolic paraboloid shape, both concave in the sagittal plane of the rider and convex in its frontal plane.…”

“…또한 불안정한 면 앉기에 대한 근 활 성도 선행연구에서 30분간 등지지대가 있는 의자와 등 지지대가 없는 의자 그리고 불안정한 면에 앉아 있는 동안 근전도 검사에 의해 총 14개 근육의 최대 근 수축 력의 값을 측정하였으나 이는 유의한 차이가 없었다 [13]. 더 나아가 Frey 등 [14]…”
