ABSTRACT
Introduction The aim of this study was to determine whether robotic-assisted locomotor training, a new clinical service introduced at the Tan Tock Seng Hospital (TTSH) Rehabilitation Centre, Singapore is effective at improving the ability to transfer and the ambulatory status of patients with an acquired brain injury.
Methods This was a retrospective review of data collected from patients with an acquired brain injury, before and after robotic-assisted locomotor training from September 2008 to May 2009. The primary outcome measures used were the functional independence measure (FIM) for transfer and ambulation, and the Rivermead Motor Assessment (RMA) gross function subscale. The secondary outcome measures used were the Motricity Index (MI) and Modified Ashworth Scale of the lower limb. Statistical analysis was performed on this data to evaluate whether robotic-assisted locomotor training was effective at improving the functional mobility of these patients.
Results Significant improvement was observed in the scores of FIM transfer (p is less than 0.05), FIM ambulation (p is less than 0.05) and RMA (p is less than 0.05) after robotic-assisted locomotor training. Significant improvements in the MI of hip flexion (p is less than 0.05), knee extension (p is less than 0.05) and ankle dorsiflexion (p is less than 0.05) post training have also been noted.
Conclusion Robotic-assisted locomotor training was found to be effective at improving the transfer, ambulation and functional mobility of patients with an acquired brain injury.
