A scoliosis treatment platform includes a seat and leg structures connected to the seat. The leg structures are configured to support the seat in a substantially horizontal orientation at a vertical position above a base upon which the leg structures are positioned. The scoliosis treatment platform also includes a frame member positioned at a fixed location relative to the seat. The frame member extends upward above the seat. The scoliosis treatment platform also includes an actuator assembly connected to the frame member. The actuator assembly includes a cushion oriented toward a region overlying the seat. The actuator assembly is configured to apply a specified force through the cushion to a specified anatomical portion of a patient when the patient is seated on the seat.
