Aotearoa New Zealand is approaching super-aged nation status. As a result, sarcopenia--age-related loss of muscle mass and function--poses escalating public health challenges, particularly for kaumātua (older Māori). This feasibility study explores the acceptability and preliminary effectiveness of low energy pulsed electromagnetic field (PEMF) therapy using the BIXEPS device as a non-invasive intervention to counter sarcopenia. Eighty-two kaumātua were randomly assigned to three groups: (1) BIXEPS only, (2) BIXEPS with weekly physical activity, and (3) delayed treatment. Interventions were conducted biweekly over two phases, with outcomes assessed at baseline, 7 weeks, and 15 weeks. Data collection included skeletal muscle mass (via InBody analysis), functional fitness testing, self-reported pain, and health-related quality of life (HRQOL). Adherence was high (84%), and participants reported positive engagement. Results showed a non-significant but promising trend (~1kg) in increased skeletal muscle mass for groups receiving PEMF. HRQOL significantly improved (p = .036) for intervention groups, with reductions in pain and enhancements in physical functioning also observed. Despite limitations, including small sample size, group imbalances in age and activity levels, and reduced data completeness at later phases, the study affirms the cultural and practical acceptability of PEMF therapy among kaumātua. The findings suggest potential for scalable, non-invasive interventions tailored to indigenous ageing populations. Future studies should incorporate larger samples, refined randomisation, and more robust retention strategies to validate efficacy. This research bridges indigenous health equity, innovative gerontechnology, and non-pharmacological therapy, contributing new insights into age-positive care models grounded in cultural responsiveness.
