This study will examine the effect of upper and lower extremity manipulations on an upper extremity balancing task.
Spinal manipulation has long been thought to have beneficial effects on posture, balance and proprioception; however, only a single study has investigated the effect of chiropractic treatment of the extremities on balance and posture. In a previous study, it was noted that lower extremity manipulation led to more ordered behavior on a dynamic, lower extremity balance task. It was also found that upper extremity manipulation led to less ordered behavior with same lower extremity balance task. Further studies are needed not only to validate this theory, but to further clarify the mechanism regarding specificity of manipulation to task.

| Upper extremity manipulation | Other | An upper extremity (glenohumeral, humeroulnar and radioulnar joints, bilaterally) or a lower extremity (coxofemoral, tibiofemoral, and tibiotalar, bilaterally) manipulation series. |
| Measure | Description | Time Frame |
|---|---|---|
| Head Sensor to calculate angle of head inclination | There will be a sensor placed on each participant's head (in a neoprene headband), as well as on the midpoint of the tube. The head sensor will be used to calculate the angle of head inclination. The sensor on the tube will be used to calculate Sample Entropy as well as general kinematics. | 30 seconds |
| Measure | Description | Time Frame |
|---|---|---|
| Ground reaction force | Participants will be standing on a force plate that will characterize their ground reaction forces, eyes open without tube (EONT) versus eyes closed without the tube (ECNT). | less than 1 minute |
| Center of pressure |
