AB, healthy group; C, cervical; CB&M, Community Balance and Mobility Scale; iSCI, incomplete spinal cord injury group; L, lumbar; LE, lower extremity; mini-BESTest, mini-Balance Evaluation Systems Test; T, thoracic; 4WW, 4-wheeled walker.

^*LE strength measured with manual muscle testing of 12 muscles per LE. Maximum score per muscle is 5, resulting in a total score of 120 for 2 LE.
