BACKGROUND: People with Multiple sclerosis (MS) have been found to impair strength and endurance of core muscles compared with healthy people. Whole body vibration (WBV) is a relatively new method of neuromuscular training which can induce positive effects on mobility and postural control of MS patients.

OBJECTIVE: To evaluate the effects of a 6-week WBV training program on the strength and endurance of core muscles in patients with MS.

METHODS: Fifty patients were allocated to two groups, one receiving WBV training (intervention) and one no treatment (control). The endurance of core muscles were evaluated using Sorensen, flexion, and side bridge endurance tests. The strength of core muscles was evaluated using a dynamometer. We used the quality of life-54 questionnaire (MSQOL-54) to evaluate patients` quality of life aspects at baseline and two months after the end of study.

RESULTS: Forty six patients completed the study (mean age: 37.9 ± 7.7; BMI: 23.8 ± 4.3). All outcome measures including strength and endurance of core muscles as well as MSQOL-54 scores significantly improved in WBV group in comparison to control group. While the within-group comparison showed significant improvement in the WBV group (P < 0.001), in the control group, some outcomes measures including physical and mental components of MSQOL-54 deteriorated (P < 0.001) over the course of study.

CONCLUSIONS: Our study shows that strength and endurance of core muscles as well as quality of life of MS patients can be positively influenced by a 6-week WBV training. The program was well-tolerated by patients and no adverse event was observed.
