| Figure 5: Raw data from a captured exercise session. Head rotation in the yaw plane (top) and pitch plane (bottom) are shown. As suggested the patient completed approximately one minute of gaze stabilization (adaptation) exercises in each plane. It is important to note that while the patient was instructed to rest for one minute between exercises in each plane, the data indicates a rest period of approximately 4 sec. The PT notes that the patient required re-education on exercise execution so the patient would include the one minute rest periods. The one minute rest period is recommended because prolonged head movements may heighten the intensity and duration of dizziness and cause the patient to avoid performing the exercises or limit other activities. Off-axis signals are also observed due to the difference in alignment between the gyroscope planes and head rotations planes. |
