Effect of Art Therapy on Cognitive and Hand Functions of Alzheimer's Patients
Effect of Art Therapy on Cognitive and Hand Functions of Alzheimer's Patients
This randomized controlled trial aims to investigate the effects of art therapy on cognitive functions and hand functions in individuals with Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder characterized by decline in memory, executive functions, and daily living activities. In addition, fine motor skills and hand-eye coordination are significantly impaired, limiting independence in daily tasks.
Art therapy is a non-pharmacological, low-cost, and feasible intervention that involves creative activities such as mandala painting, collage, clay modeling, and drawing. It has been shown to support cognitive performance, emotional well-being, and motor coordination by stimulating neuroplasticity. However, evidence focusing specifically on its impact on hand function in Alzheimer's patients remains limited.
In this study, 50 participants aged 60 years and older with mild to moderate Alzheimer's disease will be randomly assigned to an intervention group or a control group. The intervention group will attend art therapy sessions twice a week for 8 weeks (60 minutes per session), while the control group will receive no intervention. Cognitive functions will be assessed using the Mini-Mental State Examination (MMSE), and hand functions will be evaluated with the Nine Hole Peg Test (NHPT) and surface electromyography (sEMG) of forearm muscles.
The results of this study are expected to provide valuable evidence on the role of art therapy in supporting both cognitive and motor rehabilitation in Alzheimer's disease, potentially contributing to improved daily living independence and quality of life.
Alzheimer's disease is a progressive neurodegenerative disorder characterized by impairments in memory, executive functions, attention, and activities of daily living. As the disease advances, fine motor skills and hand-eye coordination are also affected, limiting independence in self-care and functional tasks. Non-pharmacological approaches that target both cognitive and motor abilities are increasingly emphasized as complementary strategies to pharmacological treatment.
Art therapy is a creative intervention that incorporates activities such as mandala coloring, collage making, clay modeling, and drawing. Previous studies have shown that art therapy may stimulate neuroplasticity, improve attention and memory, reduce anxiety and behavioral symptoms, and enhance quality of life in individuals with dementia. However, limited evidence exists regarding its specific effects on fine motor performance and hand function in patients with Alzheimer's disease.
This randomized controlled trial is designed to evaluate the effectiveness of an 8-week structured art therapy program on cognitive functions and hand dexterity in individuals with mild to moderate Alzheimer's disease. Participants (n=50) will be randomly assigned to either an intervention group receiving art therapy twice weekly for 60 minutes per session, or a control group receiving no intervention.
Outcome measures include the Mini-Mental State Examination (MMSE) for global cognitive function, surface electromyography (sEMG) of forearm muscles to assess motor activity, and the Nine-Hole Peg Test (NHPT) to evaluate fine motor dexterity. Assessments will be conducted at baseline and post-intervention.
The study hypothesizes that participants in the art therapy group will demonstrate significant improvements in cognitive performance and fine motor abilities compared to the control group. The results are expected to provide evidence supporting the integration of art therapy as a feasible, low-cost, and non-pharmacological intervention in the rehabilitation of individuals with Alzheimer's disease.
