Table 6 QPS score correlation to GMFM-66, GMFCS, MACS, PedsQLâ„¢ (Pearson correlation coefficients at baseline visit [V2])
From: Initial psychometric validation of the questionnaire on pain caused by spasticity (QPS)
QPS module | GMFM-66 | GMFCS | MACS | PedsQLâ„¢ total scorea |
|---|---|---|---|---|
Expected association | Higher GMFM-66 score [0–100] relates to better motor function and lower QPS score | Higher GMFCS/MACS levels [I–V] relate to higher disability and higher QPS score | Higher PedsQL score [0–100] relates to better QoL and lower QPS score | |
