Acupressure Improves Cognition and Quality of Life Among Older Adults with Cognitive Disorders in Long-Term Care Settings: A Clustered Randomized Controlled Trial.

OBJECTIVE

To examine the effectiveness of acupressure on cognition and quality of life (QoL) among older adults with cognitive disorders residing in long-term care (LTC) settings.

DESIGN

A clustered, randomized, assessor-blinded, controlled trial with a repeated measures design.

SETTING AND PARTICIPANTS

Participants were recruited from residential care facilities in Taiwan from August 2020 to February 2021. Ninety-two older residents in 18 facilities were randomized to either the intervention arm (9 facilities, n = 46) or the control arm (9 facilities, n = 46).

METHODS

Acupressure was performed at Baihui (GV20), Sishencong (EX-HN1), Shenting (GV24), Fengchi (GB20), Shuigou (GV26), Neiguan (PC6), Shenmen (HT7), and Zusanli (ST36). The duration for pressing each acupoint was 3 minutes. The acupressure force was maintained at 3 kg. Acupressure was performed once a day 5 times a week for 12 weeks. The primary outcome measure was the Cognitive Abilities Screening Instrument (CASI). Secondary outcomes included the digit span backward test, the Wisconsin Card Sorting Test (perseverative responses, perseverative errors, and categories completed), semantic fluency tests of categories of animals, fruits, and vegetables, and the Quality of Life-Alzheimer's Disease (QoL-AD). Data were collected at preintervention and postintervention. Three-level mixed effects models were performed. This study complied with the CONSORT checklist.

RESULTS

After adjusting for covariates, there was a significant increase in CASI scores, the digit span backward test, perseverative responses, perseverative errors, categories completed, semantic fluency tests of categories, and QoL-AD scores in the intervention versus control arm at 3 months.

CONCLUSIONS AND IMPLICATIONS

This study provides support for the use of acupressure to improve cognition and QoL during care among older residents with cognitive disorders in LTC settings. Acupressure can be integrated into aged care practice to improve cognition and QoL of older residents with cognitive disorders in LTC settings.
