Effects of different exercise modalities on ataxia in multiple sclerosis patients: a randomized controlled study

Area of Science:

• Neurology
• Rehabilitation Medicine
• Exercise Physiology

Background:

• Multiple sclerosis (MS) is a chronic central nervous system disease characterized by inflammation and autoimmune processes.
• Ataxia, a significant motorしかし, is a challenging symptom in MS patients, impacting balance and coordination.
• Current rehabilitation strategies for ataxic MS often involve various exercise modalities.

Purpose of the Study:

• To compare the effectiveness of three different exercise protocols on improving ataxia in patients with multiple sclerosis (MS).
• To determine if specific exercise combinations yield superior results for balance and coordination in MS patients.

Main Methods:

• A randomized controlled study involving 42 MS patients (EDSS 3-5) divided into three groups: balance training (BT), lumbar stabilization (LS), and task-oriented training (TT).
• All groups underwent 18 sessions of balance training, with LS and TT groups receiving additional specific exercises.
• Evaluations included Berg Balance Scale (BBS), International Cooperative Ataxia Rating Scale (ICARS), Functional Reach Test (FRT), 2-Minute Walk Test (2MWT), Sensory Organization Test (SOT), and Somatosensory Evoked Potentials (SSEPs).

Main Results:

• All exercise groups showed improvements in BBS, ICARS, FRT, 2MWT, and SOT composite balance scores.
• The TT and LS groups demonstrated significant improvements in ICARS kinetic function and SSEPs compared to BT.
• The LS and TT groups showed superior outcomes in ICARS total score and SOT composite balance compared to the BT group, with similar improvements between LS and TT.

Conclusions:

• Balance training alone is insufficient for effective rehabilitation of ataxic MS patients.
• Combining balance training with either lumbar stabilization exercises or task-oriented training significantly enhances rehabilitation success.
• Lumbar stabilization and task-oriented training should be considered complementary approaches to improve balance and coordination in MS patients with ataxia.
