OBJECTIVE: To compare the postural control of persons with a dysvascular
transtibial amputation and traumatic transtibial amputation with able-bodied
adults with and without a dysvascular condition in altered sensory testing
conditions. DESIGN: Cross-sectional study. SETTING: University balance clinic.
PARTICIPANTS: The study participants (N=35) included: participants with a
dysvascular transtibial amputation (n=9), participants with a traumatic
transtibial amputation (n=9), age-matched able-bodied adults without a
dysvascular condition (n=9), and able-bodied adults with a dysvascular condition
(n=8). INTERVENTIONS: Six Sensory Organization Test (SOT) conditions, which
included standing with eyes open (condition 1) and closed (condition 2) on a
static force platform with visual surround; standing with eyes open on a static
force platform with movable visual surround (condition 3); standing with eyes
open (condition 4) and closed (condition 5) on a movable force platform with
static visual surround; and standing with eyes open on a movable force platform
with movable visual surround (condition 6). MAIN OUTCOME MEASURES: Bilateral
anteroposterior (AP) and mediolateral (ML) center of pressure variables, namely
root mean square distance (RMSD) and mean velocity (mVel), for each of the 6 SOT
conditions. RESULTS: The dysvascular transtibial amputation group demonstrated a
higher AP RMSD (P</=.04) on the sound side than did the able-bodied adults
without a dysvascular condition and the able-bodied adults with a dysvascular
condition in SOT conditions 1 and 2, respectively. Both the dysvascular
transtibial amputation group and the traumatic transtibial amputation group
demonstrated a higher AP RMSD (P</=.002) than the able-bodied adults without a
dysvascular condition in SOT conditions 3 and 4. The dysvascular transtibial
amputation group showed higher AP mVel (P</=.002) on the sound side for SOT
conditions 2 and 3, whereas both amputation groups showed higher AP mVel for SOT
conditions 1 and 4 than the able-bodied adults with and without a dysvascular
condition. CONCLUSIONS: Postural control of the dysvascular transtibial
amputation group was not different than the traumatic transtibial amputation
group in challenging sensory conditions. However, when compared with the groups
of able-bodied adults with and without a dysvascular condition, postural
strategies distinct with amputation etiology were observed.
