Analysis of Physical-Cognitive Tasks Including Feedback-Based Technology for Alzheimer's Disorder in a Randomized...

Area of Science:

• Neuroscience
• Gerontology
• Rehabilitation Medicine

Background:

• Alzheimer's disease (AD) significantly impacts cognitive and physical functions, particularly affecting the prefrontal cortex.
• AD compromises patient autonomy and daily living activities.

Purpose of the Study:

• To assess the efficacy of physical-cognitive tasks with feedback technology on memory, attention, balance, gait, and fall risk in AD patients.
• To explore the potential of technology-assisted interventions in managing AD symptoms.

Main Methods:

• A pilot randomized controlled trial (RCT) involving 15 Alzheimer's patients (8 experimental, 7 control).
• The experimental group engaged in 16 sessions of physical-cognitive tasks with multi-modal feedback (visual, acoustic, immediate, terminal, knowledge of results/performance).
• The control group received usual care, including pharmacological treatment and standard cognitive/mobility exercises.

Main Results:

• Significant improvements were observed in the experimental group for memory (MEC score, p=0.029), balance and gait (Tinetti score, p=0.029), and reduced fall risk (Timed Up and Go test, p=0.020).
• Attention measures did not show significant changes.
• Effect sizes (d) were 0.14 for MEC and 0.68 for Tinetti.

Conclusions:

• Physical-cognitive tasks incorporating feedback technology can enhance memory, balance, gait, and reduce fall risk in Alzheimer's patients.
• The intervention shows promise for improving functional outcomes and potentially promoting treatment adherence.
• Further research with larger sample sizes is warranted to confirm these findings, especially regarding attention.
