Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Electromyographic signals of the rectus femoris collected by the HD-sEMG technique

    These signals will be confronted by the diagnosis of sarcopenia defined by the joint presence of the 2 clinical criteria of the European Working Group on Sarcopenia in Older People 2 (EWGSOP2).

    day1-day7

Secondary Outcomes (7)

  • Number of participants with falls. Definition of " fallers " : at least 1 fall in the last 12 months

    day1- day7

  • Skeletal muscle mass index (SMMI in kg/m2, skeletal muscle mass/height2) collected by DEXA

    day1-day7

  • Grip strength by dynamometer (kg)

    day1-day7

  • SPPB score (SHORT PHYSICAL PERFORMANCE BATTERY score)

    day1-day7

  • HD-sEMG muscle data, measured during lower limb quadriceps extension by High Definition Surface Electromyography HD-sEMG

    1 month post inclusion

  • +2 more secondary outcomes

Interventions

HD-sEMGOTHER

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.

Elderly patients suspected of sarcopenia

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

Elderly patients suspected of sarcopenia
