Optimizing movement quality is a common rehabilitation goal for children
with cerebral palsy (CP). The new Quality Function Measure (QFM) - a revision of
the Gross Motor Performance Measure (GMPM) - evaluates five attributes:
Alignment, Co-ordination, Dissociated movement, Stability, and Weight-shift, for
the Gross Motor Function Measure (GMFM) Stand and Walk/Run/Jump items. This study
evaluated the reliability and discriminant validity of the QFM. METHOD:
Thirty-three children with CP (17 females, 16 males; mean age 8y 11mo, SD 3y 1mo;
Gross Motor Function Classification System [GMFCS] levels I [n=17], II [n=7], III
[n=9]) participated in reliability testing. Each did a GMFM Stand/Walk
assessment, repeated 2 weeks later. Both GMFM assessments were videotaped. A
physiotherapist assessor pair independently scored the QFM from an assigned
child's GMFM video. GMFM data from 112 children. That is, (GMFCS I [n=38], II
[n=27], III [n=47]) were used for discriminant validity evaluation. RESULTS: QFM
mean scores varied from 45.0% (SD 27.2; Stability) to 56.2% (SD 27.5; Alignment).
Reliability was excellent across all attributes: intraclass correlation
coefficients (ICCs) >/=0.97 (95% confidence intervals [CI] 0.95-0.99), interrater
ICCs >/=0.89 (95% CI 0.80-0.98), and test-retest ICCs >/=0.90 (95% CI 0.79-0.99).
QFM discriminated qualitative attributes of motor function among GMFCS levels
(maximum p<0.05). INTERPRETATION: The QFM is reliable and valid, making it
possible to assess how well young people with CP move and what areas of function
to target to enhance quality of motor control.
