Motor Score Thresholds Predict Catheterization Independence in Spinal Cord Injury

In the aftermath of catastrophic spinal cord injury, one of the most intimate measures of recovered autonomy is the ability to manage one's own bladder care. A Japanese research team, following 194 people through the long arc of rehabilitation, has found that a simple numerical assessment of arm and hand strength — taken as early as four weeks after injury — can predict with remarkable accuracy who will regain that independence. The thresholds they identified are not universal but stratified by sex and age, a recognition that recovery is shaped by the full particularity of a human life.
