Comparing functional profiles of children with hemiplegic and diplegic cerebral palsy in GMFCS Levels I and II: Are separate classifications needed?

The goal was to compare children with hemiplegia with those with diplegia within Gross Motor Functional Classification System (GMFCS) levels using multiple validated outcome tools. Specifically, we proposed that children with hemiplegia would have better gait and gross motor function within levels while upper extremity function would be poorer. Data were collected on 422 ambulatory children with cerebral palsy: 261 with diplegia and 161 with hemiplegia, across seven centers. Those with hemiplegia in each level performed significantly and consistently better on gait or lower extremity function and poorer on upper extremity and school function than those with diplegia. In GMFCS Level II, the group with hemiplegia walked faster (p = 0.017), scored 6.6 points higher on Dimension E of the Gross Motor Function Measure (p = 0.017), 6.7 points lower on Upper Extremity subscale of the Pediatric Outcomes Data Collection Instrument, and 9.1 points lower on WeeFIM self-care (p = 0.002). Basing motor prognosis on GMFCS level alone may underestimate lower extremity skills of children with hemiplegia, and overestimate those of children with diplegia.

Sagittal knee kinematics after hamstring lengthening.

The purpose of this study was to analyze sagittal knee kinematics after hamstring lengthening. A retrospective analysis was performed of 16 children (32 knees) with cerebral palsy who underwent hamstring lengthening as an isolated surgical procedure. Gait analysis was performed before surgery and at a minimum of 1 year after surgery. Decreased stance maximum knee flexion, stance minimum knee flexion, swing maximum knee flexion, and swing minimum knee flexion were noted. Total knee excursion increased. The present study confirmed the previously reported increased total knee excursion with decreased stance minimum and swing maximum knee flexion.

Sagittal knee kinematics following hamstring lengthening.

The purpose of this study was to analyze sagittal knee kinematics following hamstring lengthening. A retrospective analysis was performed of 16 children (32 knees) with cerebral palsy who underwent hamstring lengthening as an isolated surgical procedure. Gait analysis was performed prior to surgery and at a minimum of one year after surgery. Decreased stance maximum knee flexion, stance minimum knee flexion, swing maximum knee flexion, and swing minimum knee flexion were noted. Total knee excursion increased. The present study confirmed the previously reported increase in total knee excursion with decrease in stance minimum and swing maximum knee flexion after hamstring lengthening.

Sagittal knee kinematics following combined hamstring lengthening and rectus femoris transfer.

The purpose of this study was to review knee kinematics following combined hamstring lengthening and rectus femoris transfer. Previous findings reported in the literature include kinematic changes in the magnitude of stance-phase maximum knee flexion, stance-phase minimum knee flexion (extension), and swing-phase maximum knee flexion; the timing of swing-phase maximum knee flexion and swing-phase minimum knee flexion (extension); and total knee excursion. Twenty-three children underwent bilateral (22) or unilateral (1) hamstring lengthening and rectus femoris transfer (45 knees) at the Shriners Hospitals for Children in Lexington, KY between January 1996 and December 2001. Sagittal knee kinematic data were obtained as part of a complete gait study accomplished before surgery and at 1 year after surgery. Values were compared using a paired t test method set at a p < .05 level to determine statistical significance. Changes were seen in the magnitude of stance-phase maximum knee flexion, stance-phase minimum knee flexion (extension), swing-phase maximum knee flexion, and swing-phase minimum knee flexion (extension); in the timing of swing-phase maximum knee flexion; and in total knee excursion.

Sagittal knee kinematics after rectus femoris transfer without hamstring lengthening.

The purpose of this study was to assess the sagittal knee kinematics of rectus femoris transfer without hamstring lengthening. A retrospective review of seventeen children (29 knees) was performed. Gait analysis was performed prior to surgery and repeated at a minimum of one year after surgery. Sagittal knee kinematics were analyzed. Stance minimum knee flexion increased 7 degrees; swing maximum knee flexion increased 5 degrees; and swing minimum knee flexion increased 5 degrees. The present study confirmed previously reported increases in swing maximum knee flexion. Increases in stance minimum knee flexion and swing minimum knee flexion were also found. These findings have not been previously reported.
