# of studies reporting psychometric properties: 2
Interpretability
- Total scores range from 0 to 50 with higher scores indicating greater functional ability
MCID: not established
SEM: not established
MDC: not established
Typical Values
- Mean (SD) of all 10 VLT Scores:
Left hand = 2.6 (1.3)
Right hand = 3.1 (1.3)
(Post et al. 2006: study 2; n=55, 46 males; tetraplegia; mean (SD) time since injury: 11.0 (8.5) years)
Reliability – High
- Internal consistency of the VLT-SV is High for both the left hand (Cronbach’s a = 0.88) and right hand (Cronbach’s a = 0.94).
- Inter-rater reliability is High for both the left hand (ICC = 0.98) and right hand (ICC = 0.99).
- Test-retest reliability is High for both the left hand and right hand (ICC = 0.90)
(Post et al. 2006: study 2; n=55, 46 males; tetraplegia; mean (SD) time since injury: 11.0 (8.5) years)
(Berardi et al. 2019, n=61; 80.3% males; mean (SD) age: 47 (14.76) years; ASIA: 25A, 15B, 15C, 6D; Italian version)
Validity – Moderate to High
- Correlation between left and right hand VLT-SV score is Moderate (Spearman’s r = 0.50)
- Correlation between the Grasp and Release Test and VLT-SV is High for both left hand (Spearman’s r = 0.87) and right hand (Spearman’s r = 0.90).
- Correlation between the Self Care-Functional Independence Measure and VLT-SV is High for both left hand (Spearman’s r = 0.61) and right hand (Spearman’s r = 0.69).
- Correlation between the Transfer-Functional Independence Measure and VLT-SV is High for both left hand (Spearman’s r = 0.71) and right hand (Spearman’s r = 0.72).
- Correlation between the ASIA Impairment Scale and VLT-SV is Moderate–High for the left hand (Spearman’s r = 0.35) and right hand (Spearman’s r = 0.69).
(Post et al. 2006: study 2; n=55, 46 males; tetraplegia; mean (SD) time since injury: 11.0 (8.5) years)
(Berardi et al. 2019, n=61; 80.3% males; mean (SD) age: 47 (14.76) years; ASIA: 25A, 15B, 15C, 6D; Italian version)
Responsiveness
There was a significant difference in VLT-SV scores across 3 measurement points (t1 = start of rehab, t2= 3 months after start of rehab, t3 = discharge).
(Spooren et al. 2006)
Floor/Ceiling Effect
No values were reported for the presence of floor/ceiling effects in the VLT-SV for the SCI population.
