Effect of a Home-Based Virtual Reality Intervention for Children with Cerebral Palsy Using Super Pop VR Evaluation Metrics: A Feasibility Study

Table 3

The scores on BOT-2 (a) and PMAL (b) in children with CP. The score of BOT-2 is also listed in Table 3(a). The MDC reported from the literature was 0.67 for the PMAL-Amount (i.e., how often) and 0.66 for the PMAL-Quality (i.e., how well).

(a) BOT-2

(b) PMAL

ID	How often			How well
	Pre	Mid	Post	Pre	Mid	Post
C1	4.636	5.000	5.000	4.591	4.955	4.955
C2	4.773	4.909	4.909	4.682	4.818	4.818
C3	2.045	2.500	2.955	1.955	2.045	3.182

The change score for “how often” needed to exceed 0.67 and for “how well” needed to exceed 0.66 to be clinically meaningful.
indicates that the PMAL score exceeded MDC between pre- and postintervention evaluation.
