Effect of a Half Pad on Pressure Distribution in Sitting Trot and Canter Beneath a Saddle Fitted to Industry...

Using a half pad beneath a saddle can be beneficial for improving saddle fit. However, there is a paucity of evidence on half pad use when used beneath a correctly fitted saddle. The aim was to quantify the effect that three different half pads have on pressure distribution beneath a saddle fitted following industry guidelines. Twelve nonlame horses were ridden by experienced riders in sitting trot and canter on each rein (three repeats). Saddle fit, with a high-withered cotton saddle cloth (control) compared with three half pads (viscoelastic gel, wool, and medical-grade, closed-cell foam), was evaluated by five qualified saddle fitters. A Pliance (Novel) pressure mat determined saddle pressures. Mean and peak pressures (kPa) beneath the saddle were compared using a general linear mixed model with horse as a random factor and half pad type and rein as fixed factors with a Bonferroni post hoc correction (P ≤ .05). In sitting trot, in the cranial region, peak (P = .008) and mean pressures (P = .03) were highest when using the gel half pad compared with the control. In the caudal region in sitting trot, mean pressures were lowest when using the wool half pad (P = .0002). In canter, increased peak (P = .04) and mean (P = .02) pressures were found in the cranial region of the saddle with the gel half pad. In canter, with the foam half pad, reduced mean pressure (P = .002) in the caudal region was found. It is essential that the use and type of a half pad, to be used beneath a well-fitted saddle, is discussed with a qualified saddle fitter.
