Publication number: 20200253809Abstract: A harness used for a locomotor training of a patient, such as a pediatric patient, is provided. The harness has a bottom strap, such as two leg straps, for providing pelvic support to the patient and a pelvic band for providing waist support to the patient. The bottom strap is releasably connected to the pelvic band. Multiple lifting straps are connected to the pelvic band. The lifting straps can be manipulated to provide partial weight support to the patient. The harness has circumferential bands of varying widths that can be easily added and removed to provide maximum trunk support to minimal or no trunk support across the length of the trunk. This allows the harness to dynamically meet the needs of trunk support as the patient advances.Type: ApplicationFiled: February 13, 2020Publication date: August 13, 2020Inventors: Andrea L. Behrman, Thomas Roussel
