  1. Development and reliability testing of the Comprehensive High-level Activity Mobility Predictor (CHAMP) in servicemembers with traumatic lower-limb loss Robert S. Gailey, PhD, PT; Ignacio A. Gaunaurd, PhD, MSPT; Michele A. Raya, PhD, PT, SCS, ATC; Kathryn E. Roach, PhD, PT; Alison A. Linberg, DPT, ATC; MAJ (Ret) Stuart M. Campbell, MPT; LTC Daniel M.

  2. Aim • Develop and determine reliability of Comprehensive High-level Activity Mobility Predictor (CHAMP). • New outcome measure consisting of Single Limb Stance, Edgren Side Step Test, T-Test, and Illinois Agility Test. • Relevance • Opportunity for wounded servicemembers to return to high-level activity and duty has improved with surgery, rehabilitation, and prosthetic technology advances. • High-level mobility outcome measure needed to assess progress toward high-level mobility during and after rehabilitation.

  3. Method • Reliability determined for servicemembers: • With lower-limb loss (LLL). • Interrater: n = 118; test-retest: n = 111. • Without LLL. • n = 97. • Developed linear system to combine CHAMP items and produce a composite score ranging from 0 to 40, with higher scores indicating better performance.

  4. Results • Intraclass correlation coefficient values: • Interrater: 1.0. • Test-retest: 0.97. • CHAMP score within range for servicemembers without LLL: • 33 points.

  5. Conclusion • CHAMP was found to be a safe and reliable measure of high-level mobility in servicemembers with traumatic LLL.
