Eligibility
Inclusion criteria
Inclusion criteria: 1. Aged >=50 years; 2. Meets the AWGS 2025 sarcopenia diagnostic framework, confirmed by low muscle strength (grip strength) and low muscle mass (measured by DXA or BIA); physical performance (5×STS, gait speed) will be recorded according to AWGS 2025 criteria as outcome measures for efficacy and prognosis analysis. 3. Physical performance: Baseline SPPB (0–12 points) will be recorded, and participants will be stratified by SPPB scores (e.g., SPPB 0–6 vs 7–9 vs 10–12) for randomization and subgroup analysis; SPPB score is not used as a diagnostic criterion for sarcopenia. 4. Frailty status: Fried phenotype score 1–3 (pre-frail/frail) or Clinical Frailty Scale (CFS) score 4–6 (mild-to-moderate frailty); CFS assessment will be completed by trained geriatricians/researchers. 5. Able to complete >=10 meters of indoor walking under supervision; 6. Signed informed consent obtained.
Exclusion criteria
Exclusion criteria: Participant-related factors: 1. Severe cognitive impairment with inability to cooperate with study procedures; 2. Participant deemed unsuitable for inclusion at the investigator’s discretion. Condition-related factors: 3. Recent acute cardiovascular or cerebrovascular events; 4. Unhealed fractures, or severe osteoporosis with recent fragility fractures; 5. Severe joint deformity or skin conditions preventing device wear; 6. Severe skin breakdown or open wounds in the device application area.
