Effectiveness of Cryotherapy on the Fatigue of Patients With Multiple Sclerosis (CRYOSEP)

April 14, 2026 updated by: Fondation Ildys

Effectiveness of Partial-body Cryotherapy on the Fatigue of Patients With Multiple Sclerosis During Readaptation Stay

the aim of the study is to evaluate the effectiveness of partial-body cryotherapy (PBC) on the symptoms of patients with multiple sclerosis during a rehabilitation stay.

Conditions

Detailed Description

Multiple sclerosis (MS) is a chronic heterogeneous disease with an unpredictable clinical course. Symptoms can include paralysis, ataxia, spasticity, incontinence and fatigue syndrome.

Fatigue is considered to be the most prevalent and disabling of the symptoms at all stages of the illness and its occurs in 70-80% of patients. This characteristic of the disease directly impacts the quality of life of patients, affecting their social and physical well being.

Physical rehabilitation is often prescribed in the management of MS, and is recognized to improve modifiable impairments in MS.

However, the benefit of physical activities may be limited by heat stress also named Uhthoff syndrome frequently observed in patients with MS.

Cryotherapy is commonly used as a method to relieve pain and inflammation without marked side effect in respect to contraindication. However well designed studies on PBC in patients with MS are still too sparse.

The investigators propose to evaluate the effectiveness of PBC on the symptoms of MS patients during a rehabilitation stay in out- or inpatients.
