A physiotherapeutic device has a waist tensioning system and a spine support system that enable correction and/or maintaining postural stance for individuals suffering from poor posture and/or neurodegenerative disease. The device provides a posture support and retention system during episodes of postural instability to enable individuals to maintain posture and balance while performing functions. The device includes a garment with shoulder straps extending from the tensioning system to generate force vectors in a direction opposite of those generated by traditional shoulder straps. A rigid support member is disposed in the garment to run parallel with the spinal column. The shoulder straps and waist straps tie into an anchor located on a portion of the garment directly over the support member. The connected components work in concert to actively and passively adjust tension and apply pressure to straighten shoulders and improve the upper back support.
