Claim:
1. A tensioning device, comprising: a patient positioning means configured to precisely, repeatedly align a target region of a patient spine; a tension producing actuator configured to place the patient spine in tension; a positioning device operationally configured to position the tension producing actuator relative to the target region of the patient spine; a patient interface device operationally configured to interface the tension producing actuator with the patient spine; a control system with feedback on a resultant tension vector applied to the patient spine operationally configured to allow for adjustment of either tension producing actuator position, patient position, or both while applying tension to the patient spine during non-therapeutic tension levels; and a display operationally configured to provide geometric data regarding the resultant tension vector to a user or healthcare provider; wherein the control system automatically adjusts tension producing actuator work levels such that a resultant tension vector magnitude remains ideally constant during adjustment of a resultant tension vector angle, reducing risk of eliciting paraspinal muscle contraction due to changes in the resultant tension vector magnitude.
