Takeaway

  • Physical exercise therapy significantly improves activities of daily living (ADL), walking, balance, and visuospatial functions in patients with dementia and mild cognitive impairment.

Why this matters

  • Findings suggest that introducing a multicomponent exercise programme with moderate intensity, including cognitive, physical, and multitasking exercises may have a greater benefit than other types of exercise.

Study design

  • Researchers at Loughborough University, UK conducted a meta-analysis of 21 studies identified through a literature search across electronic databases.

  • Funding: Dunhill Medical Trust.

Key results

  • In patients with dementia or mild cognitive impairment, physical exercise therapy was significantly effective in improving:

    • ADL (standardised mean difference [SMD] ranging from 0.27 to 1.44);

    • walking (SMD ranging from 0.08 to 2.23);

    • balance (SMD ranging from 0.37 to 2.24); and

    • visuospatial function (SMD ranging from 0.16 to 0.51).

Limitations

  • Study did not include outcomes such as cognitive functions and muscle strength which could affect the independence of individuals in ADL.
