A systematic evaluation of the effect of thumb opponens splints on hand function in children with unilateral spastic cerebral palsy.

OBJECTIVE: To examine the effects of a neoprene thumb opponens splint on hand function during a self-selected activities of daily living task in children with unilateral spastic cerebral palsy with thumb-in-palm position of the affected hand. DESIGN: Systematic evaluation of seven cases using a multiple baseline design across individuals. SETTING: Outpatient clinic. SUBJECTS: Seven children with unilateral cerebral palsy (2-7 years old), Manual Ability Classification System level 2-3 participated in the study. INTERVENTIONS: Neoprene thumb opponens splints (McKie splint) were used. Children were followed for about four months. Baseline period ranged from 4 to 9 weeks, intervention period was two months and duration of follow-up one month. MAIN MEASURES: Hand function was assessed using goal attainment scaling and visual analogue scales. Data was assessed visually. RESULTS: In four children goal attainment scaling and/or visual analogue scale scores increased after introducing the splint. These effects remained when splints were not worn. Two children only benefited from the splint when it was worn. Thumb opponens splints were tolerated well by all children who participated in this study. CONCLUSIONS: Thumb opponens splints may have a positive effect on hand function in children with unilateral spastic cerebral palsy.

Reliability of popliteal angle measurement: a study in cerebral palsy patients and healthy controls.

UNLABELLED: The popliteal angle is a widely used clinical measure for hamstring contracture in cerebral palsy (CP) patients and in healthy individuals. The reliability of popliteal angle measurement is being questioned. The aim of this study is to determine the reliability of popliteal angle measurement by means of visual and goniometric assessment. METHODS: Three different observers measured the popliteal angle in 15 CP patients and 15 healthy volunteers. In each subject, popliteal angles were visually estimated and measured with a blinded goniometer twice by all observers with approximately 1 hour between measurement sessions. RESULTS: All intraclass correlation coefficients (ICCs) were lower in the CP group compared with healthy controls. The ICC for intraobserver differences was higher than 0.75 for both groups. The ICC for interobserver reliability of visual estimates and goniometric measurements was low for both groups. Intermethod ICC was higher than 0.75 for both groups. CONCLUSIONS: Measurements in the CP group seemed to be less reliable than measurements in the control group. Intraobserver reliability is reasonable for both groups, but lower in CP patients than in controls. Interobserver reliability of both visual estimates and goniometrical measurements is poor. No significant differences in reliability have been found between visual estimation and goniometric measurement. Because of poor interobserver reliability of popliteal angle measurement, this should not be the only variable in clinical decision making in CP patients.
