Trunk sensor
Another particularly innovative feature is the possibility of applying the TK Sensor trunk sensor to all the Pro-Kin line systems.
The TK Sensor, applied to the patient’s trunk, is a biaxial clinometer capable of
detecting trunk oscillations in anterior posterior
and right-left directions. The two main applications of this sensor are:

• Assessing control of the trunk during proprioceptive exercises in erect patient position.Trunk stability during proprioceptive exercises in erect patient position, indicates that the subject has good peripheral control (ankle, knee, hip) and does not require any postural compensation at higher levels.
• Assessing control of the trunk in seated patient position.
  Using the trunk sensor whilst the patient manages the Pro-Kin system in seated position, the operator can easily “breakdown” the trunk movements into two parts: i.e. low trunk movements (pelvic) detected by the mobile platform and high trunk movements (chest) detected by the trunk sensor.
  The system software enables real-time detection of the two distinct movements.
