Main Outcome Measures: Functional performance based on 6 performance tests, physical fitness based on 7 fitness tests, and disabilities based on the self-reported ability to perform 16 daily activities.
The Pediatric Evaluation of Disability Inventory (PEDI) quantitatively measures functional performance.
Table 1 contains a short description of the tests measuring functional performance and those measuring physical fitness, grouped in three categories: strength, flexibility, and coordination.
This study describes development of a new test for measuring functional performance of the upper extremity and neck and assesses reliability and concurrent validity in patients with shoulder pathology.
These studies often used intermediary impairment measures such as knee range of motion (instead of measure of functional performance), or they used non-validated outcome measures with poor psychometric properties.
Gait speed, a measure of functional performance that predicts impaired function and mortality [ 29], was assessed using the 20 m walk test at a usual walking pace.
In such a scenario, a measure of functional performance (e.g. fruit or seed set) or robustness (competition or facilitation between native and alien species) could be used to verify the desired conservation effect.
Our findings are also in concordance with the results of the study of Ringsberg et al. [ 17], who found walking velocity, another measure of functional performance of the lower extremities, was significantly related to balance (one leg stance) in women.
Based on traditional analyses, the results of multiple studies support the use of the DASH as an appropriate measure of functional performance in persons with proximal humeral fractures [ 11], shoulder disabilities [ 12, 13], ulnar neuropathy at the elbow [ 14], rheumatoid arthritis [ 15], work-related musculoskeletal complaints [ 16], and thumb osteoarthritis [ 17].
