Effect of manual diaphragmatic release technique on exercise capacity and sleep quality in older adults with Type II diabetes: A randomized controlled trial.

In 30 seconds

This single-blind randomized controlled trial assessed a six-week manual diaphragmatic release (MDR) program in 44 older adults with type 2 diabetes. Participants received either MDR plus guided breathing exercises or breathing exercises alone, three times weekly. Compared with the control group, the MDR group had greater improvement in exercise capacity, sleep quality, fatigue, and health-related quality of life. Six-minute walk distance increased by 24.2 m versus 4.6 m (P < 0.001). The authors describe MDR with guided breathing as a promising non-pharmacological adjunct for older adults with well-controlled diabetes, while noting that broader populations need further study.

Key findings

• Six-minute walk distance increased by 24.2 m with MDR plus breathing exercises versus 4.6 m with breathing exercises alone (P < 0.001, η2 = 0.516).
• Sleep quality improved more in the MDR group, with PSQI scores decreasing significantly (P = 0.001, η2 = 0.234).
• Fatigue scores decreased significantly (P < 0.001, η2 = 0.476), and quality of life improved (P < 0.001, η2 = 0.413) in the MDR group.

Why it matters

Exercise capacity, sleep, fatigue, and quality of life can affect daily functioning in older adults with type 2 diabetes. This trial suggests that adding manual diaphragmatic release to guided breathing may improve several of these outcomes over six weeks, offering evidence for a non-pharmacological adjunct. The findings are relevant to supportive care but do not establish effects beyond the studied population or follow-up period.

What to keep in mind

The trial included 44 older adults with well-controlled type 2 diabetes and assessed outcomes only at baseline and immediately after six weeks; the authors call for research in broader diabetic populations.
