OBJECTIVE: To determine if age, pinprick scores in the lower extremities, and
neurologic severity of injury influence recovery of ambulation in persons with
motor complete, sensory incomplete (American Spinal Injury Association Impairment
Scale [AIS] grade B) spinal cord injury (SCI) 1 year after initial injury.
This retrospective analysis examined subjects with AIS grade B from the
Spinal Cord Injury Model System (SCIMS) database from 2006 to 2015. The baseline
neurologic examination at rehabilitation admission (2-4wk postinjury) was used
for comparison with 1-year outcome measures of locomotion. SETTING: Fifteen acute
inpatient rehabilitation centers (participants in the SCIMS database).
PARTICIPANTS: Participants with AIS grade B SCI (N=249) were enrolled in the
SCIMS database in 2 cycles (2006-2010 and 2011-2015). INTERVENTIONS: Not
applicable. MAIN OUTCOME MEASURES: Household ambulation at 1 year by FONE-FIM and
by direct interview, as part of the annual neurologic exam; change in American
Spinal Injury Association score 1 year postinjury. RESULTS: Findings demonstrate
a statistically nonsignificant increase in likelihood of walking for those age
<50 years compared with those age >/=50 years (relative risk [RR]=1.99; 95%
confidence interval, 0.80-3.04). Presence of pinprick in at least one half of the
lower-extremity dermatomes L2-S1 was associated with higher likelihood of walking
(RR=5.57, P=.0023). Pinprick was significant for patients age <50 years (RR=4.58,
P=.0090) but not for those age >/=50 years (P=.15). CONCLUSIONS: Compared with
younger individuals, participants age >/=50 years with AIS grade B SCI are less
likely to achieve walking function 1 year postinjury. Likewise, preservation of
pinprick sensation postinjury in the majority of lower-extremity dermatomes L2-S1
increases the chances of walking in individuals age <50 years.
