Robotic-assisted rehabilitation for balance in stroke patients (ROAR-S): effects of cognitive, motor and functional outcomes

OBJECTIVE: Due to the aging population, the incidence of stroke is steadily increasing. In patients with stroke outcomes, sensory, motor and cognitive problems limit the performance of activities of daily living. The development of new technologies in rehabilitation is improving the quality and efficiency of functional recovery. Hunova robotic platform (Movendo Technology, srl, Genoa, Italy) is a robotic device for functional assessment and rehabilitation of balance. The purpose of this study is to evaluate the effects of rehabilitation with Hunova on cognitive function and balance in older adults with stroke. PATIENTS AND METHODS: This is a randomized, controlled, single-blind study. Twenty-four older adults with stroke outcomes were randomized into the Hunova group (HuG), which performed a specific rehabilitation program for balance using Hunova for 12 sessions in addition to conventional rehabilitation, and the control group (CoG), which performed only conventional rehabilitation. All patients underwent a clinical cognitive, balance, quality of life and fatigue assessment, and an instrumental balance assessment with Hunova at the beginning and end of treatment. RESULTS: Statistical analysis showed significant improvements in most clinical scales in both groups. Comparing the groups, HuG showed greater improvements in executive functions, speed of information processing, attention and discrimination of multiple stimuli, static and dynamic balance and autonomy in daily activities, standing postural sway, and trunk control in static and dynamic conditions. CONCLUSIONS: Data analysis showed that elderly with stroke who underwent balance technology treatment with Hunova in combination with conventional treatment had a greater improvement in cognitive functions, balance and reduced risk of falling.
