Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Sarcopenia is a progressive and generalised skeletal muscle disorder involving the accelerated loss of muscle mass and function that is associated with increased adverse outcomes including falls, functional decline, frailty, and mortality.

In this pilot project, the investigators want to explore the potential of the high-definition surface electromyography technology (HD-sEMG) for the diagnosis of sarcopenia.

This is a monocentric, descriptive, cross-sectional, parallel group study to develop a new diagnostic method.

It is planned to include 50 people aged 75 years and over hospitalized in the acute geriatric ward and suspected of sarcopenia (Score ≥4 on the SARC-F screening questionnaire).

The inclusion duration will be 36 months and adding a 1-month patient follow-up as part of routine care, the total study duration will be 37 months.

Patients will have their body composition (muscle mass, fat mass, and bone mass) using dual X-ray absorptiometry (DEXA). Muscular strength will be assessed by handgrip strength. Physical performance will be assessed. Additional data will be collected from their medical records.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aging of the population is a major public health problem with its multifactorial impact on quality of life and maintenance of autonomy. Unfortunately, one consequence of aging is sarcopenia, which affects the intrinsic and functional properties of muscle. It is a risk factor for loss of autonomy, falls, frailty and is associated with increased mortality.

Sarcopenia is defined as a progressive loss of muscle mass, strength and physical performance. Classically, sarcopenia is assessed by imaging techniques (MRI, DEXA) or bioelectrical impedancemetry for aspects related to the assessment of muscle mass loss. MRI or DEXA are not widely available and/or access is limited.

For functional aspects, grip strength measurements are often used. Currently sarcopenia cannot be diagnosed and evaluated by a single examination, including both the morphological (muscle mass) and functional aspects. Furthermore, several biological markers are associated with muscle mass, strength, and function, but these biomarkers are not specific to skeletal muscle and are weakly associated with clinical goals.

Finally, despite the important interest in assessing the qualitative/functional and quantitative aspect of skeletal muscle in neuromuscular impairment, there is currently no tool that routinely assesses these aspects.

In this context, developing new approaches for non-invasive assessment of sarcopenia, is a major issue. In this pilot project, the investigators aim to develop a medical device derived from high-definition surface electromyography (HD-sEMG) technology, non-invasive and portable, for the diagnosis of sarcopenia.

Study Groups

Elderly patients suspected of sarcopenia

Group Type EXPERIMENTAL

HD-sEMG

Intervention Type OTHER

high definition surface electromyography, allowing the recording of muscle activation signals sensitive to the intensity of the contraction and indirectly to the muscle strength as well as to the muscular fatigability, but also capable of measuring the modifications of the recruitment modalities of the motor units. This recording will be made on the rectus femoris during knee extension, either in the lying position or during chair lifts, depending on the patient's functional state.

- Quadriceps muscle ultrasound

Intervention Type OTHER

Muscle Ultrasound with Philips Lumify Wireless Handheld Ultrasound for Android - Model - L12-4 linear probe, allowing performance at the patient's bed.

IPAQ Physical Activity Questionnaire.

Intervention Type OTHER

physical activity assessment questionnaire/adapted version for seniors
