Bolstering Cognitive and Locomotor Function in Post-Stroke Dementia Using Human-Robotic Interactive Gait Training

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Geriatric Neurology

Background:

• Post-stroke dementia (PSD) presents challenges in rehabilitation.
• The efficacy of human-robotic interactive gait training (HIT) in PSD remains debated.
• Optimizing gait and cognitive function in PSD patients is crucial for daily living.

Purpose of the Study:

• To compare the effects of HIT versus conventional physiotherapy (CPT) in patients with PSD.
• To evaluate the impact on cognitive, sensorimotor, and balance functions.
• To assess improvements in daily living activities performance.

Main Methods:

• Forty-eight PSD patients were randomized into HIT (n=23) or CPT (n=25) groups.
• Therapy involved 60-minute sessions, three times weekly for six weeks.
• Outcomes measured included MMSE, FMA, TIS, BBS, and MBI scores.

Main Results:

• HIT demonstrated superior improvements in Mini-Mental State Examination (MMSE), Fugl-Meyer Assessment (FMA), and Trunk Impairment Scale (TIS) scores compared to CPT (p < 0.05).
• No significant differences were observed between HIT and CPT for Berg Balance Scale (BBS) and Modified Barthel Index (MBI) scores (p > 0.05).

Conclusions:

• HIT shows promise for enhancing cognitive and sensorimotor recovery in PSD patients.
• HIT may be particularly beneficial for PSD patients unable to perform dual cognitive-locomotor tasks.
• Further research is needed to explore HIT's impact on overall balance and daily living performance.
