Multiple sclerosis (MS) patients are characterized by thermoregulatory failure, known as Uthoff's phenomenon. Precisely, 60-80% of the MS patients present adverse clinical symptoms when their body temperature is increased. Thus, the development of treatment strategies to overcome the thermoregulatory problem in these patients is crucial. Given that cooling has been proposed as an effective method, the aim of this study was to examine whether the application of head cooling therapy during an exercise training session is capable to prevent the core temperature increase and to improve the patient's functional ability and quality of life.
Multiple Sclerosis (MS) mostly affects young individuals aged between 20 to 40 years and is the leading cause of morbidity and disability in young. Most of the MS patients experience motor symptoms such as ataxia, tremor, dizziness, limb weakness and vertigo that induce gait difficulty. More precisely, it has been reported that in around 85% of patients diagnosed with MS the gait difficulties are the main problem, which increases the risk for falls. Except for the motor difficulties, MS patients experience multiple physical, cognitive and neurological symptoms that reduce their quality of life. Also, fatigue is another frequent symptom, which is considered among the most disabling symptoms. MS patients 10 years after the onset of the disease become unable to perform housekeeping and employment responsibilities, and as a consequence, the patients experience high depression rates while the suicide incidence is high, varying from 28.6% to 2.5% in these patients. Over the past 15 years a variety of studies have proved that exercise training in patients with chronic diseases, improve their functional capacity and quality of life, and accordingly are capable of performing their daily living activities independently, while it can reduce depression and delay the progression of the disease's symptoms. Nevertheless, MS patients for many years were advised not to participate in exercise training programs because there was a perception that exercise could worsen the disease symptoms due to increased body temperature. Indeed 60-80% of the MS patients present adverse clinical symptoms when their body temperature is increased not only due to physical working but even when immersing in hot water or by exposure to infrared lamps or the sun. Since MS has a severe economic impact as it affects mostly young adults in their most productive years and leads to loss of work capacity and exercise training has the potential to prevent or ameliorate this loss, the need to develop new treatment strategies that could overcome the thermoregulatory problem during exercise is crucial. Therefore, it has been proposed that active precooling is considered an effective treatment for reducing the consequences of induced-heat stress due to exercise. Therefore, this study will examine whether a session of pre-cooling could improve the functional ability of patients with MS.

Exclusion Criteria:
Assigned Interventions 10 MS patients (aged 25----50 years) with Expanded Disability Status Scale between 2 to 6.5 have agreed to participate in this study. The exercise training session involved head cooling and neck wraps. The exercise training session consisted of 40 min continuous cycling where the participants performed an incremental sub-maximal exercise protocol beginning at 45 W, increasing 10 W every 10 min for a total of four stages on a semirecumbent cycle ergometer in a 20oC room. Before and after the completion of the session each participant performed a variety of functional ability tests. The evaluation of the core temperature and the assessment of the patient's quality of life also was performed.

Before and after the completion of the session each participant performed a variety of functional ability tests. The evaluation of the core temperature and the assessment of the patient's quality of life also was performed.
Core Temperature
The core temperature was measured using a telemetric capsule or (e-Celsius Performance, BodyCap, Caen, France). Temperature at the skin surface was recorded every second at four sites using iBUTTON sensors (type DS1921 H, Maxim/Dallas Semiconductor Corp., USA) \[Tsk; 0.3 (chest C arm) C 0.2 (thigh C leg)\].
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test Handgrip
Handgrip dynamometer was used for the upper body muscle strength evaluation. Both hands was tested.
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test 2-minute walk
The two-minute walk test was applied where all the patients had to cover as far a distance as possible over 2 minutes. All the walking tests are related with the ability to perform independently the activities of daily living
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test 25-Foot Walk (T25-FW)
The 25-Foot Walk (T25-FW) was used to measure the walking speed. It is a validated test that reflects the patient's mobility and leg function performance
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test five times sit-to-stand test (STS)
The five times sit-to-stand test (STS) was used as an indicator for lower limb strength, balance and mobility. It has been reported that the STS times are associated with standing and leaning balance and mobility in older people. Slow STS time have been also found to predict subsequent disability, falls and hip fractures
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test Berg Balance Scale (BBS)
The Berg Balance Scale (BBS) evaluates the performance in specific activities that require balance function. The BBS test lasts approximately 20 minutes and involves common actions (e.g. sit to stand, picking up an object, standing on one leg e.t.c.) necessary for activities of daily living. The BBS is a 14-item list with each item consisting of a five-point ordinal scale ranging from 0 to 4, with 0 indicating the lowest level of function and 4 the highest level of function.
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test level of fatigue severity (FSS)
The FSS is a 9-item self-report scale about fatigue of certain activities. Its score includes a 7-point scale from 1 = strongly disagree to 7 = strongly agree. The minimum possible score is nine and the highest is 63. High score indicates severe fatigue. FSS takes approximately eight minutes to complete.
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test Cognitive function
Cognitive function was assessed with the mini mental state examination (MMSE) questionnaire. MMSE includes tests of orientation, attention, memory, language and visual-spatial skills. The answers in the MMSE are scored as following: 0=incorrect, 1=correct, 6= item administered, participant does not answer and 9= unknown
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test level of fatigue impact
Level of fatigue was assessed by the Modified Fatigue Impact Scale (MFIS). The MFIS contains the following sections: a) Physical Sub-scale (score 0-36), b) Cognitive Sub-scale (score 0-40) and Psychological Sub-scale (score 0-8). The total MFIS score is 0-84; 0 represents the lower score and 84 represents the higher score.
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test level of fatigue inventory
Level of fatigue was assessed by the 20-item scale Multidimensional Fatigue Inventory (MFI) questionnaire. The score of MFI is 1-7. The more the fatigue, the higher the score.
Time frame: Change from baseline to after 40 minutes of continous cycling.
Functional ability test level of physical fatigue
Level of fatigue was assessed by the Cognitive and Physical Fatigue in Multiple Sclerosis Scale (CPF-MS). The CPF-MS score is 1-5. The more the fatigue, the higher the score.
Time frame: Change from baseline to after 40 minutes of continous cycling.
