A method of signal processing in motion analysis of the trotting horse

Accuracy and precision of hind limb foot contact timings of horses determined using a pelvis-mounted inertial measurement unit

“…The proposed method can therefore be used for the analysis of pathological gait, where features are commonly independent of the exact foot contact (e.g. Buchner et al, 1996;Peham et al, 1996;Uhlir et al, 1997;Audigie et al, 2002;Keegan et al, 2003Keegan et al, , 2004Kramer et al, 2004). Since none of the features expressed as % stride was dependent on Froude Number or stride duration, no systematic changes of the foot contact estimate relative to the gait cycle should be expected with increasing trotting speed.…”

Understanding hind limb lameness signs in horses using simple rigid body mechanics

“…This approach was based on the experimental evidence that movement patterns of lame horses can be reconstructed from A1 and A2 with near 100% reconstruction (Peham et al, 1996;Audigie et al, 2002). The pattern of the sacrum trajectory was controlled by varying the phase relationship φ between symmetrical (A2) and asymmetrical (A1) component from 0.25π to π (for examples see Fig.…”

Computer-assisted kinematic evaluation of induced compensatory movements resembling lameness in horses trotting on a treadmill

“…[4][5][6][7] Computer-assisted kinematic gait analysis has been used to establish objective lameness evaluation techniques that could be adapted for clinical use. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] Studies 13,14,18-23 have revealed that kinematic evaluation of vertical motion of the head and pelvis in relation to vertical movement of the feet on 1 side of the body is all that is required to detect lameness and differentiate the affected limb.…”
