The relationship between horse and rider is a complex one. Compensations, imbalances or weaknesses in the rider can cause musculo-skeletal changes in the equine that can affect their performance. Vice versa, musculo-skeletal changes and imbalances in the equine may over time affect the riders muscle balance as they have to compensate for reduced function or reluctance to work in a particular way. This could lead to a continued cycle of dysfunction, imbalance, pain and poor performance.
