The Effects of High-Intensity Interval Training on Gait, Balance, and Cognitive Functions in Individuals With Multiple Sclerosis (HIIT-MS)

18. mai 2026 oppdatert av: Kübra Turan, Hacettepe University

Investigating the Effects of High-Intensity Interval Training on Gait, Balance, and Cognition in Individuals With Multiple Sclerosis

This study aims to comparatively investigate the effects of low-volume High-Intensity Interval Training (HIIT) versus Moderate-Intensity Continuous Training (MICT) on gait, balance, cognitive functions, and neurovascular biomarkers (BDNF, VEGF) in individuals with Multiple Sclerosis (MS). This randomized controlled trial will be conducted at Hacettepe University, Faculty of Physical Therapy and Rehabilitation.

Detaljert beskrivelse

Individuals with MS aged 18 and older, with an EDSS score of 0-4, no relapse in the past three months, and medically stable condition will be randomized into two groups using a sealed-envelope method. Group 1 will receive MICT on a cycle ergometer (twice weekly, 8 weeks); Group 2 will receive low-volume HIIT with the same frequency. Both groups will receive an individualized physiotherapy program after each aerobic session. Outcomes include gait (TUG, T25FW, DGI), balance (Mini-BESTest, mCTSIB), cognitive function (BICAMS: SDMT, CVLT-II, BVMT-R), exercise capacity (ISWT), and blood biomarkers (BDNF, VEGF) assessed via ELISA.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: MICT Group (Moderate-Intensity Continuous Training)
Cycle ergometer-based MICT, twice weekly for 8 weeks, starting at 60% of peak workload, progressing to 80%. Sessions include 5-min warm-up, 20-30 min exercise, 5-min cool-down, followed by 30-min individualized physiotherapy.
Atferdsmessig: Moderate-Intensity Continuous Training (MICT)
Cycle ergometer-based exercise, twice weekly for 8 weeks. Starting intensity at 60% of peak workload, progressing to 80%. Each session includes 5-min warm-up, 20-30 min continuous exercise, and 5-min cool-down, followed by 30-min individualized physiotherapy program.
Eksperimentell: HIIT Group (High-Intensity Interval Training)
HIIT on cycle ergometer, twice weekly for 8 weeks. Protocol: 5-min warm-up (40% peak workload), 10 × 1-min intervals at 90% peak workload with 1-min active recovery (60% peak workload) between each, followed by 5-min cool-down. Total session: ~20 min aerobic + 30-min individualized physiotherapy.

Tidsramme
Timed Up and Go Test (TUG)
Tidsramme: Baseline and 8 weeks
Timed Up and Go Test (TUG). Participants are asked to rise from a standard chair, walk 3 meters, turn around, walk back, and sit down as fast as safely possible. Measured in seconds. Lower values indicate better functional mobility and balance.

Incremental Shuttle Walk Test (ISWT)
Tidsramme: Baseline and 8 weeks
Incremental Shuttle Walk Test (ISWT). Participants walk between two cones placed 9 meters apart at increasing speeds guided by audio signals until they can no longer maintain the required pace. Measured in meters walked. Higher values indicate better functional exercise capacity.
Baseline and 8 weeks
Mini Balance Evaluation Systems Test (Mini-BESTest)
Tidsramme: Baseline and 8 weeks
Mini Balance Evaluation Systems Test (Mini BESTest). Assesses dynamic balance across 14 items in 4 subsections: anticipatory postural control, reactive postural control, sensory orientation, and dynamic gait. Minimum score: 0, Maximum score: 28. Higher scores indicate better balance performance.
