The Clinical Outcome Measures Electronic Toolkit (COMET) provides a library of fifteen useful clinical outcome measures for prosthesis and orthosis (P&O) users and clinicians. COMET simplifies and standardizes the use of outcome measures for daily clinical practice by enabling practitioners to easily select the appropriate measure, administer the test(s), and immediately receive the results as a printable/exportable PDF document to inform evidence-based clinical care and to be included in the patient’s electronic health record.
