Validation of vertical ground reaction forces on individual limbs calculated from kinematics of horse locomotion.
Abstract: The purpose of this study was to determine whether individual limb forces could be calculated accurately from kinematics of trotting and walking horses. We collected kinematic data and measured vertical ground reaction forces on the individual limbs of seven Warmblood dressage horses, trotting at 3.4 m s(-1) and walking at 1.6 m s(-1) on a treadmill. First, using a segmental model, we calculated from kinematics the total ground reaction force vector and its moment arm relative to each of the hoofs. Second, for phases in which the body was supported by only two limbs, we calculated the individual reaction forces on these limbs. Third, we assumed that the distal limbs operated as linear springs, and determined their force-length relationships using calculated individual limb forces at trot. Finally, we calculated individual limb force-time histories from distal limb lengths. A good correspondence was obtained between calculated and measured individual limb forces. At trot, the average peak vertical reaction force on the forelimb was calculated to be 11.5+/-0.9 N kg(-1) and measured to be 11.7+/-0.9 N kg(-1), and for the hindlimb these values were 9.8+/-0.7 N kg(-1) and 10.0+/-0.6 N kg(-1), respectively. At walk, the average peak vertical reaction force on the forelimb was calculated to be 6.9+/-0.5 N kg(-1) and measured to be 7.1+/-0.3 N kg(-1), and for the hindlimb these values were 4.8+/-0.5 N kg(-1) and 4.7+/-0.3 N kg(-1), respectively. It was concluded that the proposed method of calculating individual limb reaction forces is sufficiently accurate to detect changes in loading reported in the literature for mild to moderate lameness at trot.

This research aimed to test whether the forces exerted by individual limbs of trotting and walking horses could be accurately calculated based on their movement patterns. The study found that the calculated and actual limb forces closely matched, suggesting the method used could potentially detect changes in limb loading in cases of mild to moderate lameness in horses.
Study Methodology
- In this study, the kinematic data was collected and the vertical ground reaction forces were measured on the individual limbs of seven Warmblood dressage horses. The horses were made to trot at a speed of 3.4 m/s and walk at 1.6 m/s on a treadmill.
- Firstly, a segmental model was used to calculate the total ground reaction force vector and its moment arm relative to each of the horse’s hoofs from the kinematics.
- Next, for phases in which the horse’s body was supported by only two limbs, the individual reaction forces on these limbs were calculated.
- The research then assumed that the distal limbs operated as linear springs, and determined their force-length relationships using the calculated individual limb forces at a trot.
- Lastly, individual limb force-time histories were calculated from the lengths of the distal limbs.
Key Findings
- Comparing the calculated and measured individual limb forces showed a strong correspondence. For example, the average peak vertical reaction force on the forelimb during a trot was calculated to be 11.5±0.9 N kg(-1) and measured to be 11.7±0.9 N kg(-1). Similarly, for the hindlimb, these values were 9.8±0.7 N kg(-1) and 10.0±0.6 N kg(-1), respectively.
- The same consistency was evident during a walk. The average peak vertical reaction force on the forelimb was calculated to be 6.9±0.5 N kg(-1) and measured to be 7.1±0.3 N kg(-1). For the hindlimb, these values were 4.8±0.5 N kg(-1) and 4.7±0.3 N kg(-1), respectively.
Conclusion
- The results demonstrated that the proposed method of calculating individual limb reaction forces is accurate enough to detect changes in loading that have been reported in instances of mild to moderate lameness in horses during a trot.
