Summary

The Proto-Aging study aims to define experimental protocols and guidelines to enable the development of musculoskeletal models (digital twins) of elderly people, with the ultimate goal to comprehensively characterize frail elders from a biomechanical standpoint.

It is typical for the elderly to present with weakness, slowed movements and reduced levels of physical activity, all of which may be related to the loss of muscle force (dynapenia). Unfortunately, to date, the primary cause for dynapenia is difficult to identify. Digital twins may help to this end, but their development remains critical as it requires a specialized skillset and experimental data for model personalisation.

In this study, where the investigators will recruit a small group of frail elders and a cohort of healthy young individuals, all participants will undergo the following examinations: (i) gait assessment, (ii) maximal voluntary isometric contraction (MVIC) test, (iii) superimposed neuromuscular electrical stimulation, and (iv) full lower limb magnetic resonance imaging. Surface electromyography data will further be collected while the subjects perform both the gait assessment and the MVIC test. Last, clinical questionnaires will be administered, and the subjects will be asked to perform additional clinical measures (i.e., hand-grip test, bioelectrical impedance analysis).

At the end of the study, a reduced version of the experimental protocol will be developed, with the intent to provide clinicians with a protocol that can be deployed in clinical settings, accounting for the observed reliability and repeatability of each measure, the required level of expertise, and the associated costs and time expenditure.

Conditions

  • Frail Elderly Syndrome

Interventions

DIAGNOSTIC_TEST

Comprehensive Biomechanical assessment

Magnetic resonance images, electromyography and dynamometry data will be used, together with data from the gait assessment and clinical questionnaires/measures, to characterize the biomechanics of the participants, and to develop and inform personalised musculoskeletal models
