BACKGROUND: Elderly individuals with type 2 diabetes mellitus (T2DM) often experience reduced ventilatory function and functional capacity, which negatively impact their quality of life (QoL), yet effective non-pharmacological interventions remain limited.
OBJECTIVE: To determine the effect of manual diaphragmatic release (MDR) added to aerobic training (AT) on ventilatory function, functional capacity, and QoL, compared to AT alone in elderly women with T2DM.
METHODS: Sixty elderly type 2 diabetic women were randomly assigned in equal numbers to either the MDR or control group. For 8 weeks, the MDR group received MDR in addition to AT, while the control group received AT alone. Outcomes included measures of forced vital capacity (FVC) and total lung capacity (TLC), 6 min walk test (6MWT), and Diabetic Quality of Life Questionnaire (DQoL). Between-group differences were analysed by ANCOVA.
RESULTS: At the end of the study, there were significant group effects for all outcome measures ( p < 0 . 05 ). Adjusted between-group differences favoured the MDR group for FVC (mean difference = 3 . 17 % ; 95% CI: 1.07-5.27), TLC (mean difference = 2 . 28 % ; 95% CI: 1.22-3.33), 6MWT distance (mean difference = 22 . 58 m; 95% CI: 10.17-34.99), and DQoL score (mean difference = 0 . 94 ; 95% CI: 0.31-1.57).
CONCLUSION: Adding MDR to AT is more beneficial than AT only for enhancing ventilatory function, functional capacity and QoL in such elderly type 2 diabetic women. However, further studies with larger sample sizes and longer intervention durations are warranted to confirm these findings.
