The effects of electroacupuncture and the Otago Exercise Program in older adults with sarcopenia: A randomized controlled study

Background: The aim of this study was to investigate the effects of a combination of electroacupuncture (EA) and the Otago Exercise Program (OEP) for sarcopenia in older individuals and provide treatment recommendations for this patient population. Methods: In this assessor-blinded randomized controlled trial, 120 older patients with sarcopenia were randomly divided into an OEP group (n = 58) and an EA + OEP group (n = 62). The OEP group received OEP 5 times/week, with each session lasting 30 minutes, for a duration of 12 weeks. In addition to OEP treatment, the EA + OEP group was treated with EA at ST31, ST32, GB34 and ST36 for 30 minutes 3 times/week for 12 weeks. The appendicular skeletal muscle mass-height index (ASM/H 2 ) was the primary outcome. The secondary outcomes included grip strength, 4-m gait speed and 6-min walk distance. Outcomes were measured before initiation and at 6 and 12 weeks after initiation. Results: Significant differences in ASM/H 2 , grip strength, 4-m gait speed and 6-min walk distance were detected between the 2 groups at week 12, whereas no differences were detected at weeks 0 and 6. In the EA + OEP group, as the treatment time increased, ASM/H 2 , grip strength, 4-m gait speed and 6-min walk distance increased significantly. In the OEP group, as the treatment time increased, no significant difference was found in ASM/H 2 , whereas grip strength, 4-m gait speed and 6-min walk distance increased significantly ( P < .05). Conclusion: In older patients with sarcopenia, EA + OEP was associated with increased skeletal muscle mass, but no such effect was found for OEP alone. Moreover, EA + OEP was superior to OEP alone in terms of improving muscle strength and walking ability. EA + OEP may be considered an effective treatment for sarcopenia in older adults.
