TL;DR: Both the LCI and LCI-5 captured the global locomotor ability of people with lower-limb amputation during prosthetic training, with the LCi-5 showing a larger effect size during the rehabilitation period and a lower ceiling effect.

TL;DR: The new PEQ-MS12/5 presents good psychometric characteristics for measuring mobility in people with lower limb amputations and provides an already applicable instrument and a solid basis for further validation studies.

TL;DR: Rasch analysis provided the rationale for improving the measurement qualities of the LCI-5, refining its rating scale (through category diagnostics), identifying those items most useful for measuring the intended construct (as per the indexes of unidimensionality and internal construct validity) and showing that one can place high confidence in the consistency of both the person-ability and item-difficulty estimates obtained.

TL;DR: Findings for the LCI/5 (PPA) and MO (PEQ) are encouraging and confirm their sound practical and psychometric features, and their structure would need some refinement and simplification in order to facilitate a broader clinical use.

TL;DR: When applied in lower limb amputees, the Rivermead Mobility Index is an ordinal measure with adequate levels of a series of psychometric properties, which seems more useful for epidemiological studies than for clinical decision-making in single patients.
