[Abstract] The Beneficial Effects of Mind-body Exercises for People with Mild Cognitive Impairment: A Systematic Review with Meta-Analysis

Highlights

  • A meta-analysis on 1298 adults with MCI was conducted.
  • The effects of mind-body exercises (MBE) on various cognitions was assessed.
  • Various MBEs, such as Tai Chi, were effective in enhancing numerous cognitive outcomes.

Abstract

Objective

To objectively evaluate the most common forms of mind body exercise (MBE) (Tai Chi, Yoga, and Qigong) on cognitive function among people with MCI.

Data sources

We searched six electronic databases (Scopus, PubMed, PsycINFO, WanFang, Web of Science, and CNKI) from inception until September, 2018.

Study Selection

Nine randomized controlled trials and three non-randomized controlled trials were included for meta-analysis.

Data Extraction

Two researchers independently performed the literature searches, study selection, data extraction, and methodological quality assessment using the revised Physiotherapy Evidence Database (PEDro) scale.

Data Synthesis

The pooled effect size (standardized mean difference, SMD) was calculated while random-effect model was selected. Overall results of the meta-analysis (N = 1298 people with MCI) indicated that MBE significantly improved attention (SMD = 0.39, 95% CI 0.07 to 0.71, p = 0.02, I2 = 31.6%, N = 245), short-term memory (SMD= 0.74, 95% CI 0.57 to 0.90, p < 0.001, I2 = 0%, N = 861), executive function (SMD = -0.42, 95% CI -0.63 to -0.21, p < 0.001, I2 = 38.54%, N = 701), visual-spatial/executive function (SMD = 0.35, 95% CI 0.07 to 0.64, p < 0.05, I2 = 0%, N = 285), and global cognitive function (SMD = 0.36, 95% CI 0.2 to 0.52, p < 0.001, I2 = 15.12%, N = 902). However, the significant positive effect on cognitive processing speed was not observed following MBE interventions (SMD = 0.31, 95% CI -0.01 to 0.63, p = 0.054, I2 = 28.66%, N = 233).

Conclusions

Study findings of this meta-analysis suggest that MBE have the potential to improve various cognitive functions in people with MCI.
