Title: Use of the novel optokinetic chart stimulation based OKCSIB protocol for upper limb recovery in dense acute strokes: Insights for future research from a case control series
Biography: Benjamin Chitambira
Background: This presentation aims to report on the use of optokinetic chart stimulation based OKCSIB protocol for upper limb recovery in dense acute strokes as well as discuss insights for future research. Methods: The optokinetic chart is made of laminated A4 paper. It consists of repeated bundles of the colours of the rainbow. The chart is placed 20 centimetres in front of a patient’s face. It is moved from side to side at approximately one cycle per second for 3 minutes. This is followed by moving the chart up and down for 3 minutes and then forwards and backwards for another 3 minutes. The affected paralysed hand was also used for aiding balance by holding on during sensory interaction for balance for 3 minutes. This was then followed by 5 repetitions each for specific active-assisted anti-gravity extensor exercises of the upper limb. Results: Dense acute strokes treated by the OKCSIB protocol had statistically significant upper limb recovery when compared to those treated by conventional neurophysiotherapy (P < 0.05). The OKCSIB protocol also led to statistically significant prevention of affected hand spasticity (p < 0.05) Conclusion: Optokinetic chart stimulation shows promise as a novel recovery focused upper limb rehabilitation intervention. The key to these results may be in the restoration of anti-gravity extensor tone by cortico-vestibulospinal descending motor output to the affected upper limb. Further research with fully powered randomized controlled trials is required to provide evidence for its inclusion in future guidelines.
