Functional Muscle-Bone Incongruity Index (FKUI): Combined Evaluation of Handgrip Strength, Total Hip Bone Mineral Density, and Lumbar-Hip Bone Mineral Density Discordance in Adults Undergoing DXA
The Functional Muscle-Bone Incongruity Index (FKUI) is a novel approach developed to evaluate the relationship between muscle function and bone health. This prospective observational study aims to investigate the clinical applicability of FKUI, which combines handgrip strength, total hip bone mineral density (BMD), and lumbar-hip BMD discordance. Approximately 200 adult participants undergoing routine DXA assessment will be enrolled. The study will examine whether the combined evaluation of muscle function and bone health parameters provides a more comprehensive assessment of musculoskeletal status than individual measures alone.
• Age 18 years or older
• Attendance at the Physical Medicine and Rehabilitation outpatient clinic
• Scheduled to undergo routine bone mineral density assessment by DXA as part of clinical evaluation
• Ability to perform handgrip strength testing
• Availability of lumbar spine and total hip bone mineral density measurements suitable for analysis
• Ability and willingness to provide written informed consent
