= Prosthesis Evaluation Questionnaire.
Overall, the LCI-5 has demonstrated good test-retest reliability and internal construct validity, which was established with the PEQ
, in elderly and middle-aged populations with amputation [20-21,23].
Subjects' function, satisfaction, and QOL were self-assessed with the PEQ
They were administered in the following order: (1) PEQ
, (2) self-reported number of falls, (3) self-reported number of stumbles, (4) 75 m SSWS on even terrain [22-23], (5) 75 m FPWS on even terrain [22-25], (6) 38 m FPWS on uneven terrain , (7) 6 m FPWS on even terrain [22-38], (8) stair descent test (MRPP) , and (9) knee preference .
The ambulation subscale of the PEQ
consists of eight items on the level of prosthetic use and comfort during walking, stair climbing, and walking on uneven ground that are assessed by means of a visual analogue scale.
The resulting phylogenetic encephalisation quotient (PEQ
), to correct for the effects of close evolutionary relationships, for Chilecebus is relatively small, at 0.79.
These values can be converted into population equivalents (PEQ
) and are estimated to be about 250,000 PEQ
(in 2015, Belfast City had a population of 334,000).
