Abstract—Returning wounded veterans and servicemembers to their highest level of function following traumatic injury is a priority of the Departments of Defense and Veterans Affairs. We surveyed 245 veterans from the Vietnam war and 226 ser- vicemembers and veterans from Operation Iraqi Freedom/ Operation Enduring Freedom (OIF/OEF) conflicts with at least one major traumatic lower-limb loss to determine their use of mobility assistive technology (AT) and patterns of limb aban- donment. Prosthetic device use without wheelchair use is found in 50.5% of Vietnam and 42.8% of OIF/OEF groups. Prostheses and supplementary wheelchairs are used by Viet- nam (32%) and OIF/OEF (53%) groups (p < 0.01). Exclusive wheelchair use is more frequent in the Vietnam group (18%) than in the OIF/OEF group (4.0%, p < 0.01). In Vietnam partici- pants, multivariate analysis found that multiple-limb loss (adjusted odds ratio [AOR] = 14.5; 95% confidence interval [CI] 5.5–38.5), bilateral lower-limb loss (AOR = 12.7; 95% CI
–26.1), and number of comorbidities (AOR = 1.3; 95% CI
–1.5) are associated with increased likelihood of wheelchair
use. In OIF/OEF participants, bilateral lower-limb loss (AOR = 29.8; 95% CI 11.0–80.7), multiple-limb loss (AOR = 16.3; 95% CI 3.1–85.3), cumulative trauma disorder (AOR = 2.4; 95% CI 1.2–4.9), and number of combat injuries (AOR = 1.4;
95% CI 1.2–1.7) are associated with wheelchair use. Combined use of different types of mobility ATs promotes improved reha- bilitation and ability to function.
Key words: combat operations, mobility, mobility assistive technology, OIF/OEF, prosthetic device, rehabilitation, trau- matic amputation, Vietnam, wheelchair, wounded servicemember.
