Perhaps the most overlooked aspect of managing PD is how to maintain and strengthen
body structure. The fact that many PD patients suffer from the distinct postural deformity
of severe forward head carriage, increased curvature of the upper back and forward
flexed arms is not by coincidence. This “stooped” posture is caused by many factors
including spinal rigidity, loss of normal subconscious posture control, poor balance, and a
loss of normal proprioception (movement sensation of the joints).
