Investigation of the Prevalence of Sarcopenia and Dynapenia According to Disease Stage in Patients With Multiple Sclerosis and Evaluation of the Relationship Between Sarcopenia Severity and Clinical and Functional Parameters (MS-Sarcopenia)

21. september 2026 opdateret af: Süleyman Korkusuz, Atılım University

This cross-sectional observational study aims to determine the prevalence of sarcopenia and dynapenia across disability stages in patients with multiple sclerosis (MS) and investigate their associations with clinical and functional parameters. Approximately 150 patients will be classified into two groups according to their Expanded Disability Status Scale (EDSS) scores: mild disability (EDSS < 4.0) and moderate disability (EDSS 4.0-6.5). Sarcopenia and dynapenia will be assessed using the ISarcoPRM algorithm. Physical activity, fatigue, and functional independence will also be evaluated.

Detaljeret beskrivelse

Participants will undergo assessments of handgrip strength, five-times sit-to-stand performance, and ultrasound-based muscle mass using the Sonographic Thigh Adjustment Ratio (STAR). Sarcopenia and dynapenia will be classified according to the ISarcoPRM algorithm. Additional assessments will include the SARC-F questionnaire, smartwatch-derived physical activity, Modified Fatigue Impact Scale (MFIS), Functional Independence Measure (FIM), and Barthel Index. The prevalence of sarcopenia and dynapenia will be compared between disability groups, and associations with clinical and functional parameters will be examined.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Prevalence of Sarcopenia
Tidsramme: Baseline

Sarcopenia will be classified using the ISarcoPRM algorithm based on low muscle mass (STAR) combined with reduced handgrip strength and/or physical performance. Prevalence will be calculated as the percentage of participants meeting the criteria in each EDSS group.
Baseline
Prevalence of Dynapenia
Tidsramme: Baseline

Dynapenia will be defined as reduced muscle strength, independently of muscle mass, based on low handgrip strength (<32 kg for men; <19 kg for women) and/or prolonged five-times sit-to-stand time (≥12 seconds). Prevalence will be calculated as the percentage of participants meeting the criteria in each EDSS group.
Baseline

Sekundære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Handgrip Strength
Tidsramme: Baseline

Handgrip strength will be measured using a calibrated hand dynamometer. The highest value from at least two trials will be recorded in kilograms (kg).
Baseline
Five-Times Sit-to-Stand Test
Tidsramme: Baseline

Participants will be asked to stand up and sit down five times without using their arms. Completion time will be recorded in seconds. A duration of 12 seconds or longer will indicate reduced physical performance.
Baseline
Sonographic Thigh Adjustment Ratio (STAR)
Tidsramme: Baseline

Anterior thigh muscle thickness will be assessed using ultrasonography and adjusted for body mass index to calculate STAR. Low muscle mass will be defined as STAR <1.0 in women and <1.4 in men.
Baseline
Sarcopenia Risk (SARC-F)
Tidsramme: Baseline

Sarcopenia risk will be assessed using the five-item SARC-F questionnaire. Total scores range from 0 to 10, with higher scores indicating greater risk. A score of 4 or higher indicates sarcopenia risk.
Baseline
Modified Fatigue Impact Scale (MFIS)
Tidsramme: Baseline

Fatigue will be assessed using the 21-item MFIS. Total scores range from 0 to 84, with higher scores indicating a greater impact of fatigue on daily functioning.
Baseline
Functional Independence Measure (FIM)
Tidsramme: Baseline

Functional independence will be assessed using the 18-item FIM. Total scores range from 18 to 126, with higher scores indicating greater independence in daily activities.
Baseline
Barthel Index
Tidsramme: Baseline

Independence in activities of daily living will be assessed using the Barthel Index. Total scores range from 0 to 100, with higher scores indicating greater functional independence.
