Time points for assessing level of mobility from premorbid function to 12 months after amputation. *The patient’s recall of his or her mobility before a decline in function due to disability in the limb that underwent amputation. One subject died after enrollment before the locomotor capability index (LCI) score could be assessed. **Subjects who were enrolled presurgically completed the LCI questionnaire then and at 6 weeks to assess their premorbid mobility. These two scores demonstrated strong agreement with a Spearman correlation coefficient of 0.83 (P < .003).
