25
Why is grip strength an important measure?
It predicts poor patient outcomes such as longer hospital stays and increased functional limitations ## Footnote Low grip strength is associated with poor health-related quality of life and death.
26
What equipment is commonly used to measure grip strength?
The Jamar dynamometer ## Footnote Other brands are being explored but Jamar is widely validated.
27
What does the chair stand test measure?
Strength of leg muscles, specifically the quadriceps muscle group ## Footnote It assesses the time taken to rise from a seated position multiple times.
28
How can muscle quantity be estimated?
Using techniques like MRI, CT, DXA, and BIA ## Footnote Muscle quantity can be reported as total body Skeletal Muscle Mass (SMM) or Appendicular Skeletal Muscle Mass (ASM).
29
What are gold standards for non-invasive assessment of muscle quantity?
MRI and CT ## Footnote They are high-cost and require trained personnel, limiting their use in primary care.
30
What does DXA measure?
Total body lean tissue mass or appendicular skeletal muscle mass non-invasively ## Footnote DXA results can vary between brands, affecting consistency.
31
What is bioelectrical impedance analysis (BIA) used for?
To estimate total or appendicular skeletal muscle mass based on body electrical conductivity ## Footnote BIA is affordable and portable but requires careful calibration.
32
What does muscle quality refer to?
Micro- and macroscopic changes in muscle architecture and function per unit of muscle mass ## Footnote It is assessed using imaging tools and strength-to-mass ratios.
33
What is the creatine dilution test?
A method to estimate whole-body muscle mass using deuterium-labelled creatine ## Footnote It correlates well with MRI measures of muscle mass.
34
What is the significance of gait speed in assessing sarcopenia?
It is a reliable predictor of adverse outcomes related to sarcopenia such as disability and mortality ## Footnote A cut-off speed of ≤0.8 m/s indicates severe sarcopenia.
35
What does the Short Physical Performance Battery (SPPB) assess?
Gait speed, balance, and chair stand performance ## Footnote A score of ≤8 points indicates poor physical performance.
36
What is the purpose of the Timed-Up and Go test (TUG)?
To evaluate physical function through a series of movements ## Footnote The test involves rising from a chair, walking to a marker, and sitting down.
37
What is the role of specific biomarkers in diagnosing sarcopenia?
To identify and monitor the condition through markers related to muscle function and inflammation ## Footnote A panel of biomarkers may be more effective than a single biomarker due to the complexity of sarcopenia.
38
What is the advantage of using ultrasound for muscle assessment?
It provides reliable measures of muscle quantity and quality ## Footnote Ultrasound can detect changes in muscle thickness and cross-sectional area efficiently.
39
What does calf circumference predict in older adults?
Performance and survival ## Footnote A calf circumference cut-off point of <31 cm is significant.
40
What does muscle strength correlate with?
Strength in other body compartments ## Footnote Grip strength serves as a surrogate for more complicated strength measures.
41
What is the disadvantage of DXA?
It is not portable for community use ## Footnote DXA measurements can also be influenced by patient hydration status.
42
What is sarcopenia?
A muscle disease rooted in adverse muscle changes that accrue across a lifetime
43
What is the main indicator of probable sarcopenia according to EWGSOP2?
Low strength
44

55
True or False: Sarcopenia can occur due to malnutrition.
True
56
