Abstract:
1. A portable spinal orthotic backrest, comprising a back support plate, the back support plate being integrally formed of a plastic material and comprising, from top to bottom in a vertical direction: an upper portion having a vertical, central longitudinal cross-section with an inner-side curvature conforming to a kyphotic curvature of a person's thoracic vertebrae, the upper portion having an inner side protrudingly provided with a plurality of protruding knobs corresponding in position to two lateral sides of the thoracic vertebrae, the upper portion having a horizontal transverse cross-section with an inner-side curvature conforming to a horizontal curvature of the person's back that corresponds in position to the thoracic vertebrae, the inner side of the upper portion being concave and having an upwardly decreasing width; a lower portion having a vertical, central longitudinal cross-section with an inner-side curvature conforming to a lordotic curvature of the person's lumbar vertebrae, the lower portion having an inner side protrudingly provided with a plurality of protruding knobs corresponding in position to two lateral sides of the lumbar vertebrae, the lower portion having a horizontal transverse cross-section with an inner-side curvature conforming to a horizontal curvature of the person's back that corresponds in position to the lumbar vertebrae, the inner side of the lower portion being concave and having a downwardly decreasing width such that a joining section between the upper portion and the lower portion extends to two lateral sides of the person's back that are adjacent to a joining section between a bottom end of the thoracic vertebrae and an upper end of the lumbar vertebrae; and at least a conductive metal element being embedded and enclosed in the plastic material of the back support plate and having an end electrically connected to a transcutaneous electrical nerve stimulation (TENS) device, wherein each said protruding knob has a top end provided with an electrode, and the electrodes are electrically connected to a second end of the conductive metal element in order to receive electrotherapy signals from the TENS device through the conductive metal element.
