Abstract:
A continuous passive lumbar motion (CPLM) therapy device for exercising a lumbar spine region that is between an upper torso and a lower torso of a subject, said device comprising:a platform including a fixed frame having a first end and a second end and a sliding platform slidably mounted on said fixed frame; a height-adjustable support seat mounted on said sliding platform, said support seat having a front support and a back support, each of which rises substantially vertically from said support seat, wherein said support seat with said front support and said back support provides a secure seating for said lower torso and restrains said lower torso from moving forward or rearward relative to said support seat while exercising; a translational-motion drive that drives said sliding platform in a horizontal, cyclical motion in a forward direction toward said first end of said fixed frame and a rearward direction toward said second end, wherein a rearward travel of said sliding platform toward said second end is co-planar and 180Â° different from a forward travel of said sliding platform in toward said first end; and a control means mounted on said platform, said control means providing adjustability of an operating frequency of said cyclical motion within a frequency range that allows said upper torso of said subject to move relative to said lower torso at said lumbar spine region.
