EWGSOP2 Sarcopenia Algorithm
Applies the EWGSOP2 algorithm for sarcopenia and returns probable, confirmed or severe.

Example
- Sex, for the cutoffs
- Male
- Grip strength, kg
- 24 kg
- Appendicular skeletal muscle mass, kg
- 18 kg
Result: confirmed sarcopenia: a grip of 24 kg below 27, with a muscle mass of 18 kg
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Probable
- Low muscle strength alone: a grip below 27 kg in men or 16 kg in women, or five chair rises above 15 seconds. EWGSOP2 says intervention can begin here.
- Confirmed
- Low strength with low muscle quantity: appendicular muscle mass below 20 kg in men or 15 kg in women, or an index below 7.0 or 5.5 kg per square meter.
- Severe
- Confirmed sarcopenia with low physical performance: gait speed at or below 0.8 meters per second, a battery score at or below 8, a Timed Up and Go at or above 20 seconds, or a failed 400 meter walk.
- Strength first
- The 2019 revision moved strength ahead of muscle mass deliberately. Nothing downstream is read until strength is low.
- Performance
- Grades severity; it does not diagnose. A slow gait speed with normal strength is not sarcopenia by this algorithm.
- Case finding
- SARC-F at 4 or more, or clinical suspicion. It is a prompt to measure, not part of the diagnosis.
What you enter
- Sex, for the cutoffs
- Grip strength, kg (low below 27 in men, 16 in women)
- Five chair rises, seconds (low strength above 15)
- Appendicular skeletal muscle mass, kg (low below 20 in men, 15 in women)
- Muscle mass index, kg per square meter (low below 7.0 in men, 5.5 in women)
- Gait speed, meters per second (low at or below 0.8)
- Short Physical Performance Battery, 0 to 12 (low at or below 8)
- Timed Up and Go, seconds (low at or above 20)
- A 400 meter walk was not completed, or took 6 minutes or more
