OBJECTIVE: The aim of this study was to evaluate the effect on spasticity, muscle strength and motor performance after 8 weeks of whole-body vibration training compared with resistance training in adults with cerebral palsy. METHODS: Fourteen persons with spastic diplegia (21-41 years) were randomized to intervention with either whole-body vibration training (n=7) or resistance training (n=7). Pre- and post-training measures of spasticity using the modified Ashworth scale, muscle strength using isokinetic dynamometry, walking ability using Six-Minute Walk Test, balance using Timed Up and Go test and gross motor performance using Gross Motor Function Measure were performed. RESULTS: Spasticity decreased in knee extensors in the whole-body vibration group. Muscle strength increased in the resistance training group at the velocity 30 degrees /s and in both groups at 90 degrees /s. Six-Minute Walk Test and Timed Up and Go test did not change significantly. Gross Motor Function Measure increased in the whole-body vibration group. CONCLUSION: These data suggest that an 8-week intervention of whole-body vibration training or resistance training can increase muscle strength, without negative effect on spasticity, in adults with cerebral palsy.

BACKGROUND: Standing is believed to have benefits in addressing motor and sensory impairments after stroke. One device to facilitate standing for severely disabled patients is the Oswestry Standing Frame. OBJECTIVE: To evaluate the effectiveness of the Oswestry Standing Frame for severely disabled stroke patients. DESIGN: A single centre, randomized controlled trial. SETTING: An inpatient stroke rehabilitation unit. SUBJECTS: Patients were recruited if they had a clinical diagnosis of stroke, were medically stable and unable to achieve any score on the Trunk Control Test or unable to stand in mid-line without the assistance of two therapists. INTERVENTION: The intervention (n = 71) and control (n = 69) groups both received usual stroke unit care but the intervention group also received a minimum of 14 consecutive days’ treatment using the standing frame. MAIN OUTCOME MEASURES: The primary outcome measure was the Rivermead Mobility Index (RMI). Secondary measures included the Barthel Index; the Rivermead Motor Assessment; the balanced sitting and sitting to standing components of the Motor Assessment Scale; the Trunk Control Test and the Hospital Anxiety and Depression Scale. Blind assessment was undertaken at baseline, six weeks, 12 weeks and six months post stroke. Information on resource use was also collected. RESULTS: There was no statistically significant difference between groups in any of the outcome measures or for resource use. Mann-Whitney U-tests for the RMI change from baseline scores to six weeks, 12 weeks and six months post stroke were p = 0.310; p = 0.970 and p = 0.282, respectively. CONCLUSION: Use of the Oswestry Standing Frame did not improve clinical outcome or provide resource savings for this severely disabled patient group.

H-reflexes have been used to assess the effect of various postures on the excitability of the soleus motor neuronal pool. The purpose of this study was to determine if the excitability of the motor neuron pool, measured via H-reflexes in a seated position, change after a standing protocol in able-bodied individuals. We hypothesized that the excitability of the motor neuronal pool is minimally affected by the standing protocol leading to a reproducible H-reflex. Ten healthy individuals (height = 69.05+/-2.27 inches, weight = 161.7+/-22.44 lbs, age = 27.7+/-7.0 years) participated in the study. Soleus H-reflex recruitment curves were established before and after a standing protocol in a seated position. The standing protocol involved 12 minutes of active upright standing interspersed with 10 minutes of relaxed passive standing in a standing frame, similar to a protocol currently used for spinal cord injured subjects. The maximum M-waves and H-reflex amplitudes were not systematically changed before and after standing. There was also a strong agreement between the H-reflexes and M-waves measured before and after standing (ICC = 0. 99 and .96, respectively). We conclude that the H-reflexes measured in this study were reproducible, indicating that standing had no long lasting effect on the motor neuronal pool excitability. The findings support that the method discussed in this report is appropriate to assess the effects of electrically induced standing on motor neuron pool excitability in individuals with spasticity from spinal cord injury.
