Effects of Seated Postural Stability and Trunk and Upper Extremity Strength on Performance during Manual Wheelchair Propulsion Tests in Individuals with Spinal Cord Injury: An Exploratory Study
Table 3
Pearson product-moment correlation coefficient () between the clinical, static trunk strength, seated reaching test, and U/E strength outcome measures versus the performance-based timed manual wheelchair tests. For each wheelchair performance test, correlation coefficients highlighted in bold represent the variable entered in its multiple regression analysis (i.e., or ). Note that the proportion of the variance () in the wheelchair performance tests that is predictable from each independent variables can be computed by squaring the value () reported in the present table.
