A second analysis was completed to investigate the relationship between ULAT and DASH scores by affected limb only.
To review the degree of association between the two assessments, the study participants were assessed using both the ULAT and the DASH.
Relationships between left sided ULAT domains and total DASH score were all weak and statistically non-significant (range = .
Correlations between total ULAT and DASH scores by affected upper-limb, were moderate at a statistically significant level for the right affected side only (r = .
Given the apparent overlap in constructs between five of the eight ULAT assessment domains (i.
Significant correlations were only achieved for the 'right side' ULAT assessment domains of tone, spasticity and coordination, and 'right side affected' domains of tone, spasticity and sensation.
Overall, these results infer that the ULAT and DASH assessments measure differing aspects of neurological upper-limb function, thus the constructs being measured by the two individual assessments are similar but not associated with each other.
In the future, it is recommended that larger research trials be undertaken to examine the psychometric properties of the ULAT in more detail.
In comparing ULAT total assessment scores against the DASH self-report questionnaire, concurrent validity was generally deemed to be poor.
Within an acute neurological population, the study results collectively indicate insignificant to moderate levels of statistical association between the ULAT assessment domains and total DASH score.
