• 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.
