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)
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.

Gedetailleerde beschrijving
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.

Wat meet het onderzoek?
Primaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Prevalence of Sarcopenia
Tijdsspanne: 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
Tijdsspanne: 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

Secundaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Handgrip Strength
Tijdsspanne: 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
Tijdsspanne: 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)
Tijdsspanne: 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)
Tijdsspanne: 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)
Tijdsspanne: 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)
Tijdsspanne: 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
Tijdsspanne: 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. |
