Sway of the Center of Gravity in Patients with Spinal Canal StenosisHANAI, KENJI, MD; ISHII, KANAME, MD; NOJIRI, HAJIME, MDSpine: November 1988 - Volume 13 - Issue 11 - p 1303-1307 Original Article: PDF Only Buy Abstract Author InformationAuthors In this study the sway of the center of gravity was observed In patients with spinal canal stenosis, In order to observe the movement of the center of the gravity after the onset of claudicatlon. In normal subjects the sway of the center of gravity was restricted to a small area, but in patients with spinal stenosis, the center of gravity was diverted to the left or right side. With claudicatlon, the center of gravity moved forward. Following several rest periods, the center of gravity returned to the Initial area. The time required to return to the Initial area was longer than for a patient's subjective recovery from the symptoms.
