  2. Aim • Examine relationship between factors modifiable by rehabilitation interventions, other factors related to lower-limb loss, and high-level mobility as measured by Comprehensive High-Level Activity Mobility Predictor (CHAMP) in servicemembers with traumatic lower-limb loss. • Relevance • Many servicemembers who experience traumatic lower-limb loss seek return to Active Duty and high-level mobility activities such as sports.

  3. Method • Participants: 118 male servicemembers. • Separate regression models of factors predicting CHAMP scores were developed using stepwise regression analysis.

  4. Results • Regression models containing both rehabilitation factors and other factors explained CHAMP score variation: • 81% (unilateral transtibial amputations). • 36% (unilateral transfemoral amputations). • 91% (bilateral lower-limb amputations). • Rehabilitation factors (e.g., lower-limb strength, dynamic balance) were significantly related to CHAMP score. • Can be enhanced with appropriate intervention.

  5. Results • Findings support importance of salvaging knee joint and its effect on high-level mobility capabilities. • J-shaped energy storage and return feet improve high-level mobility for servicemembers with transtibial amputation.

  6. Conclusion • Results could guide rehabilitation and development of appropriate interventions to maximize high-level mobility for servicemembers with traumatic lower-limb loss.
