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

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.

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.

Patients benefiting from 15 session of "sham" partial-body cryotherapy session (-30°C) during their full-time rehabilitation stay

Patients benefiting from 15 session of "sham" partial-body cryotherapy session (-30°C) during their part-time rehabilitation stay

Patients benefiting from 15 session of "sham" partial-body cryotherapy session (-120°C) during their full-time rehabilitation stay

Patients benefiting from 15 session of "sham" partial-body cryotherapy session (-120°C) during their part-time rehabilitation stay

The cryotherapy procedure consisted of a 2-3 min stay in the cryotherapy chamber: at -30°C for sham cryotherapy session at -120°C for cryotherapy intervention session. For Inpatients, cryotherapy session will be performed daily, late in the afternoon, excluding saturdays and sundays, during 3 weeks. (15 sessions) For outpatient, cryotherapy session will occured late in the afternoon each day care (15 sessions).

evaluation of the fatigue syndrome using the fatigue severity scale score (FSS). The scale ranges in value from 9 to 63 with high scores indicating the worse outcome.

Primary outcome will be analyzed separately in outpatient versus inpatient in order to determine whether hospitalisation pattern may impact the effectiveness of cryotherapy on fatigue. evaluation of the fatigue syndrome using the fatigue severity scale score (FSS). The scale ranges in value from 9 to 63 with high scores indicating the worse outcome.
