Content and psychometric properties of functional measurements in patients with sarcopenia based on ICF / 中国康复理论与实践

ABSTRACT

Objective To explore the content and psychometric properties of sarcopenia measurements for older adults. Methods Using the International Classification of Functioning,Disability and Health(ICF)linking and coding rules,a content analysis were conducted on the seven types of measurement tools for geriatric sarcopenia,including Strength,Assistance with walking,Rising from a chair,Climbing stairs,and Falls(SARC-F);Ishii Test;Mini Sar-copenia Risk Assessment-7(MSRA-7);6-minute walk test(6MWT);Barthel Index(BI);Short Physical Perfor-mance Battery(SPPB);and World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0),and psychometric property was explored. Results The seven measurement tools can be categorized into body functions and structures,activities and participation,and comprehensive categories.ICF coding for SARC-F involved muscle power functions(b730),walking(d450),changing basic body position(d410),etc.Ishii Test involved muscle power functions(b730)and weight maintenance functions(b530).MSRA-7 involved walking(d450),involuntary movement reaction functions(b755),muscle endurance functions(b740),etc.ICF coding for 6MWT involved walking(d450).SPPB involved changing basic body position(d410),control voluntary movement functions(b760),and walking(d450).BI in-volved eating(d550),drinking(d560),washing oneself(d510),caring for body parts(d520),etc.WHODAS 2.0 involved attention functions(b140),acquiring skills(d155),communication-receiving-verbal messages(d310),community life(d910),etc.SARC-F was low to medium in sensitivity,and medium to excellent in specificity.Ishii Test was medium to good in sensitivity,average to good in specificity,and good in diagnostic performance.MSRA-7 was medium to good in sensitivity,average in specificity,and average to medium in diagnostic perfor-mance,while MSRA-5 was average to good in sensitivity,average in specificity,and medium in diagnostic per-formance.6MWT was average to medium in sensitivity,and average in specificity.SPPB was average in sensitiv-ity,average to medium in specificity,and average to excellent in diagnostic performance.BI was good in reliabili-ty,and WHODAS 2.0 was excellent in reliability. Conclusion The measurement tools for sarcopenia can be categorized into body functions and structures,activities and participation,and comprehensive assessment tools combining the above.The psychometric properties of the sev-en measurement tools are low to excellent in sensitivity and average to excellent in specificity.
