Clinician agreement on gait pattern ratings in children with spastic hemiplegia.

The level of agreement between clinicians' ratings of gait patterns in children with spastic hemiplegia was investigated using the Winters, Gage, and Hicks (WGH) classification scale. Sixteen clinicians (nine physiotherapists, seven orthopaedic surgeons) from six gait laboratories in five different countries rated gait patterns in 34 children with spastic hemiplegia (22 males, 12 females; mean age 10y [SD 3y], range 6-18y). Archived three-dimensional gait reports (kinematic and video data) and videos (video clips only) were rated for each child. Agreement between clinicians was substantial for reports (weighted kappa [wkappa] 0.77, range 0.62-0.89). Agreement was lower for videos (wkappa 0.63, range 0.39-0.97) and for clinicians' agreement between reports and corresponding videos (wkappa 0.62, range 0.47-0.76). Exact agreement was unacceptable for some gait patterns using reports (mean 65%, range 32-74%) and videos (mean 53%, range 35-94%). Not all gait patterns could be rated using the original WGH categories. It was concluded that: (1) agreement is acceptable using the WGH tool; (2) kinematic data from 3D instrumented gait analysis and video should be used together when using the WGH scale; and (3) further refinement of this classification is required.

Multilevel orthopaedic surgery in group IV spastic hemiplegia.

Most children with spastic hemiplegia have high levels of function and independence but fixed deformities and gait abnormalities are common. The classification proposed by Winters et al is widely used to interpret hemiplegic gait patterns and plan intervention. However, this classification is based on sagittal kinematics and fails to consider important abnormalities in the transverse plane. Using three-dimensional gait analysis, we studied the incidence of transverse-plane deformity and gait abnormality in 17 children with group IV hemiplegia according to Winters et al before and after multilevel orthopaedic surgery. We found that internal rotation of the hip and pelvic retraction were consistent abnormalities of gait in group-IV hemiplegia. A programme of multilevel surgery resulted in predictable improvement in gait and posture, including pelvic retraction. In group IV hemiplegia pelvic retraction appeared in part to be a compensating mechanism to control foot progression in the presence of medial femoral torsion. Correction of this torsion can improve gait symmetry and function.

Hip surveillance in children with cerebral palsy. Impact on the surgical management of spastic hip disease.

We studied prospectively the impact of a hip surveillance clinic on the management of spastic hip disease in children with cerebral palsy in a tertiary referral centre. Using a combination of primary clinical and secondary radiological screening we were able to detect spastic hip disease at an early stage in most children and to offer early surgical intervention. The principal effect on surgical practice was that more preventive surgery was carried out at a younger age and at a more appropriate stage of the disease. The need for reconstructive surgery has decreased and that for salvage surgery has been eliminated. Displacement of the hip in children with cerebral palsy meets specific criteria for a screening programme. We recommend that hip surveillance should become part of the routine management of children with cerebral palsy. The hips should be examined radiologically at 18 months of age in all children with bilateral cerebral palsy and at six- to 12-monthly intervals thereafter. A co-ordinated approach by orthopaedic surgeons and physiotherapists may be the key to successful implementation of this screening programme.

The effect of botulinum toxin type A and a variable hip abduction orthosis on gross motor function: a randomized controlled trial.

Hip displacement is the second most common deformity after equinus in children with cerebral palsy (CP), and may result in dislocation, pain, fixed deformity and loss of function. We studied the combined effects of intramuscular injections of botulinum toxin type A (BTX-A) to the adductors and hamstrings and a variable hip abduction orthosis (SWASH), on gross motor function, hip displacement and progression to surgery, in a randomized clinical trial. Thirty-nine children, with bilateral spastic cerebral palsy, and mean age 3 years + 2 months (range 1 year+7 months--4 years +10 months) entered the trial. Gross Motor Function Classification System (GMFCS) levels were as follows: one child was level II, 11 were level III, 13 were level IV and 14 were level V. After concealed randomization, 20 were allocated to the control group and 19 to the intervention group. Thirty-five children completed the follow up at 1 year. The novel intervention group received up to 4.0 U BOTOX/kg/muscle, 16 U/kg/body weight every 6 months plus the use of a SWASH brace. The control group received clinical best practice comprising physiotherapy but no hip abduction bracing. Both groups showed improvements in total Gross Motor Function Measure (GMFM) score [mean 6.0% BTX-A group; 6.1% Control; 95% CI -- 6.7, 6.5 (NS)], however, there was no additional treatment effect for the study group. There were similar improvements on GMFM goal scores and GMFM-66 scores, but again no additional treatment effect was observed. Multiple regression of change in total GMFM by GMFCS classification for each group showed greater improvement in the total scores from baseline in the BTX-A/SWASH treated group than the control group. In the first year, nine children (two in the intervention group and seven in the control group) required soft tissue surgery because of progressive hip migration in excess of 40%. A longer-term follow up of a larger cohort may be required to determine the effect of the combined treatment on hip displacement.

The art of pain management.

Pain assessment is fundamental to the successful management of pain. Effective communication, in particular the use of empathy, underpins assessment. Concepts within the art of nursing can usefully be applied to the understanding of pain.

Perioperative care of the visually impaired.

Eighty-three per cent of sensory input is received optically. Sight impaired patients thus experience substantial sensory deficit, so nursing any visually impaired patient through surgery requires special considerations.
