Overview
Muscle strength, function, SARC-F and functional risk.
Clinical relevance
Sarcopenia may reduce mobility, increase fall risk and compromise autonomy. Recognizing signs such as weakness, slow gait or difficulty standing helps decide when to seek professional assessment.
Signs and symptoms
- Loss of strength.
- Difficulty climbing stairs.
- Recurrent falls.
- Reduced physical activity.

Clinical assessments
SARC-F
Initial screening for sarcopenia.
Purpose: Identify sarcopenia risk.
Interpretation: A high score indicates risk and the need for assessment.
Start assessmentFrailty
Observation of vulnerability and functional decline signs.
Purpose: Organize signs associated with frailty.
Interpretation: Accumulated signs indicate the need for professional assessment.

FAQ
No. Sarcopenia is loss of strength and muscle mass; frailty is a broader state of vulnerability. They can coexist.
It is not described as curable, but strength exercise and adequate nutrition can improve strength and muscle function in many cases.
No. SARC-F organizes risk signs; diagnosis depends on a more complete professional assessment.
Seek assessment for loss of strength, difficulty climbing stairs or standing up, recurrent falls or reduced physical activity.
