“…A treadmill equipped with a dynamometric platform combines the benefits of kinetic analysis with the advantages of the treadmill, such as control of movement velocity and data acquisition over multiple consecutive motion cycles of all four limbs simultaneously ( Fig. 1) [72].…”

“…However, the use of force plate technology in horses is largely limited to experimental settings, mainly because forces created by different limbs simultaneously in contact with the plate cannot be separated, and the limited force plate dimensions preclude recording consecutive strides. Therefore, gathering force plate data of all four limbs requires numerous trials or the use of an instrumented treadmill (Weishaupt et al, 2002;Weishaupt, 2008).…”

a b s t r a c tSubtle lameness in horses may be difficult to diagnose and methods to evaluate lameness objectively are useful when equine clinicians fail to reach a consensus. The aim of this study was to determine whether equine pressure plate measurements are repeatable when used to calculate forelimb loading (peak vertical pressure [PVP], peak vertical force [PVF], vertical impulse [VI]) and symmetry ratios, and to establish if these data are similar to the 'gold standard' force plate values. Since plate dimensions are relatively small, ponies were used to enable recordings to be taken from both forelimbs in one trial. Five sound ponies were walked and trotted over a pressure plate which was embedded in a custom-made runway. For each pony, five valid trials were recorded during two different days. A trial was considered valid if complete prints of both fore hooves were recorded consecutively and if velocity was within a preset range.The PVP, PVF and VI values showed an acceptable variability (CV 6 16%), with PVF (130% of bodyweight [BW], n = 5) similar to previously reported force plate data (128% BW, n = 48). Mean symmetry ratios appeared to be high (>95%) and showed a low variability (CV < 5%). The stand-alone pressure plate permitted adequate registration of forelimb PVF, VI and limb symmetry with a high level of precision in sound ponies.

“…Data were recorded on a high-speed treadmill (Mustang 2200, Graber AG, Fahrwangen, Switzerland) with integrated force measuring system (Weishaupt et al, 2002). After warming up a static file was recorded with the rider sitting in neutral spine and pelvic alignment.…”

The objectives were to compare sagittal plane posture of the pelvis, trunk and head of elite dressage riders when they ride actively to train the horse versus sitting passively and following the horses' movements at trot, and to evaluate the effects of these changes in rider posture on load distribution on the horse's back. Synchronised motion capture and saddle mat data of seven elite dressage riders were used to measure minimal and maximal angles and range of motion (ROM) for the pelvic, trunk and head segments, the angle between pelvis and trunk segments, phase-shift between pitching motions of pelvis and trunk, and pelvic translation relative to the saddle. Non-parametric statistical tests compared variables between the two rider postures. In the passive rider posture the pelvis, trunk and head showed two pitching cycles per stride. Maximal posterior and anterior pelvic rotation occurred, respectively, early and late in the horse's diagonal stance phase. Compared with pelvic movements, trunk movements were slightly delayed and head movements were out-of-phase. In the active rider posture the pelvis and trunk pitched further posteriorly throughout the stride. Most of the riders showed similar sagittal plane movements of the axial body segments but with some notable individual variations.

Abstract: This instrumented treadmill allows a reliable assessment of load distribution and interlimb coordination in a short period and, therefore, is suitable for use in experimental and clinical investigations.
