Building a device-free system to prevent fractures in older people with musculoskeletal ambulatory disability symptom complex

This study aimed to measure the physical ability to cope with daily life and perceptions of older people at high risk of sarcopenia. We surveyed parameters to predict the risk of sarcopenia and factors worsening the condition. We used a pretest among five participants to check the relevance and validation of measures for (1) physical function, (2) physical activity, (3) environmental factors, and (4) subjective daily living activities. We plan to use these as the basis to develop a device-free sensor system to predict the onset and deterioration of sarcopenia in older people. Four participants had reduced muscle mass or left and right imbalances in one or both legs. All participants had consistent levels of vigorous and moderate activity and good sleep status. They also all kept to the protocol and wore the equipment for a whole month without any missing data. We will use the results of this pilot survey to identify changes and influencing factors for sarcopenia among older people.
