I like the theory, but I actually dont think the data would be all that useful.
A - my horses sports massage can already tell I have an injury, based on what my horse reflects. It would be super if there was something I could do about that, but I cant. Its a permanent injury for me and I do the best I can.
My horse also has a permanent issue from a scar that we just need to keep loose and it causes no issues. So my point is, none of us are perfect, showing us how we arent - likely doesnt help fix that.
B - just because a horse is showing as tracking crooked, or a rider is, how can the pad determine which is the chicken or the egg, and how can one determine the long term consequences of such? It cant. Or even diagnose the reasons for it being so.
Diagnostic aids help identify the injury, what this pad is proposing is diagnosing a possible maybe injury somewhere, and who knows where.
A crooked horse may be a sign oof navicular, suspensory, muscle weakness, kissing spines, SI, or lack of conditioning and bad training. It might be a crooked rider. If the pad tells me my horse is crooked, I only need to ride a straight line to know that myself!
So im either missing something, or it seems like its just data collection for the sake of it.
