The aim of this study was to evaluate the effects of a modified version of constraint‐induced (CI) movement therapy on bimanual hand‐use in children with hemiplegic cerebral palsy (CP; age range 18mo to 4y) and to make a comparison with conventional paediatric treatment. Twenty‐one children (13 females, eight males) completed the CI therapy programme and 20 children (12 males, eight females) served as a control group. Children in the CI therapy group were expected to wear a restraint glove for 2 hours each day over a period of 2 months. The training was based on principles of motor learning used in play and in motivational settings. To evaluate the effect of treatment, the Assisting Hand Assessment (AHA) was used. Assessments took place on three occasions: at onset, after 2 months, and 6 months after the first assessment. A significant interaction was found between group and AHA measure (ANOVA, F2,74=5.64, p=0.005). The children who received CI therapy improved their ability to use their hemiplegic hand significantly more than the children in the control group after 2 months, i.e. after treatment. Effect size was high after treatment and remained medium at 6 months. As the treatment was tailored to each child's capacity and interests, little frustration was experienced by the children.
Mirror movements in individuals with hemiplegic cerebral palsy (CP) may result from a reorganization of the central sensorimotor system. Motor performances of both hands were measured to characterize mirror activity (or mirroring) and hand functions in 22 participants (6 to 18 years) with hemiplegic CP and in 17 control participants. During a unimanual repetitive squeezing task, contractions of the active hand and fingertip forces of the opposite hand were recorded simultaneously. In the control group, slight mirror activity (or mirroring) was found that decreased with age. In participants with CP, mirror activity was 15 times stronger than in the control group, and was found at all age levels. Mirroring was more prominent in the unaffected hand of the CP group. The amount of mirror activity was not related to the degree of hemiplegia, which was assessed with measures of spasticity, strength, and dexterity. Mirror movements disturbed functional bimanual skills, although to some extent they could be suppressed by voluntary effort.
One hundred and five children with the whole spectrum of obstetric brachial plexus (OBP) injuries, from severe to full recovery, were examined at the age of 5 years with regard to motor and sensory functions as well as to use of the affected limb. Since root involvement level does not fully reflect the degree of disability, a classification based on range of motion and grip‐strength was formulated and found to correspond well with functional abilities. The results from this study indicate that the eventual outcome in upper‐plexus lesions is more complex than is commonly believed. Hand function is affected due to the effect of limited shoulder movements on hand positioning. Grip strength was also reduced in many of these children. All the children with total‐plexus lesions had diminished grip strength and half of them had impaired tactile sensibility. In most children with total‐plexus lesions, performance of activities in daily life was affected as were bimanual activities requiring use of the involved limb. Hand preference was affected in children with a right‐sided injury. From a clinical perspective, as well as for research, it is important to describe OBP injuries not only in terms of impairment but also of disability.
