Patients were exposed to very low pulsed electromagnetic field induced by BEMER machine model type: B.BOX Professional using magnet mattress.

Balance training was done using the Wii Fit plus machine which required balance board .Using video game console designed by Nintendo.

The program consisted of three games: soccer heading, ski slalom and table tilt.

Patients in the placebo group had identical program to magnet group. They were asked to lie down in the magnet mattress; however, the magnet was not switched on and the patient doesn't know (blind).

healthy subjects with age, gender and BMI matched with the patients with MS were recruited to participate in the study. This group was recruited to establish the normal balance and fatigue parameters. Subjects in this group sign the consent form of healthy subjects and all measurement was taken as balance, fatigue, depression, quality of life and urinary incontinence screening questionnaire.

Low pulsed electromagnetic field induced by BEMER machine model type: B.BOX Professional, model NO: 420200, 12-15 Volt, with maximum 300 Watt and average flux density around 35 microtesla- (BEMER Liechtenstein product, USA). Mattress which is flexible, 6 flat coil was used for whole body therapy.

It is a 21 items standardized questionnaire. Each item has five levels of response (range from 0 - 4). The total score ranges from 0 (no impact of fatigue) better condition to 84 (maximum impact of fatigue)worse condition.

Berg Balance Scale (BBS)range from 0(worse condition) to 56(better condition)

Activities- specific Balance Confidence scale .it is 16 items ofvisual analogue scale from 0-100%.score from 0 minimum confidence (worse condition) to 1600 maximum score (better condition).

It is 21 questions with each item range from 0 (normal) to 3 (most severe) with a maximum score of 63 (worse condition).The total score of the scale was used to classify patients as follows: normal (1-10), mild mood disturbance (11-16), border line of depression (17-20), moderate depression (21-30), severe depression (31-40), extreme depression (over 40)

stability levels range from 1 to 10, with 10 being the most stable or least difficult to perform. Static balance was measured at three different levels of stability; high level 8, medium 5 and low level 2. These levels where chosen to test patient balance on varying degree of instability.Patient who was unable to do the test due to sever balance impairment was given a score of 5000 based on the manufacturer recommendations in the machine manual (maximum score can subject got) which mean sever imbalance.

The SF-36 consists of eight scaled scores as vitality (energy/fatigue), physical functioning, bodily pain, general health perceptions, and physical role functioning, emotional role functioning, social role functioning and mental health.each item is scored from 0-100 for total 1800. The lower the score the more the disability. The higher the score the less disability.
