Balance Trunk is an innovative seated robotic platform dedicated to the evaluation and rehabilitation of the lumbopelvic complex and deep core stabilizers. By testing the patient in a seated posture with the lower extremities supported, Balance Trunk eliminates lower-limb compensatory strategies, directly isolating and retraining the multifidus, transverse abdominis, and pelvic stabilizers.
Technology & Hardware Architecture
The ergonomically sculpted anatomical seat tilts dynamically across anteroposterior and latero-lateral planes, challenging core stabilizers under micro-electronically controlled resistance.
Isolated Pelvic Motion: Disengages leg muscles to ensure deep core muscle activation.
Controlled ROM: Programmable angular limits protecting spinal fusion or acute disc injuries.
Adjustable Restraints: Ergonomic pelvic safety belts ensure patient security and proper posture.
Records real-time angular displacement, pelvic tilt symmetry, and trunk oscillation, quantifying lumbopelvic mobility in degrees and trajectory smoothness.
Optical Encoders: Sub-degree angular resolution detecting micro-instability.
Pelvic Rhythm Tracking: Evaluates coordinate rhythm between pelvis and lumbar spine.
Zero Guarding Bias: Eliminates muscle guarding through progressive biofeedback guidance.
Patients perform interactive biofeedback exercises to steer an on-screen cursor through complex geometric pathways using only subtle contractions of the transverse abdominis, multifidus, and pelvic floor.
Neuromuscular Re-education: Restores motor control lost due to chronic low back pain.
Pelvic Floor Coordination: Strengthens pelvic floor synergy with abdominal wall stabilizers.
Functional Endurance: Builds spinal postural endurance for sedentary desk workers and athletes.
