Introduction: MS is a progressive autoimmune disease that damages the myelin sheath of neuron axons and, depending on the location and severity of the damage, leads to motor and cognitive disorders. The aim of the study was to investigate the effects of 12 weeks of submaximal aerobic exercise on balance, flexibility, and bilateral coordination of women with MS.
Research Method: This study was conducted on 30 women with mild MS in Kermanshah city with an age range of 18 to 40 years and a disability level of up to 5.5 on the EDSS scale. The volunteers were randomly divided into two groups of 15 people: control and experimental. Tests were administered before the exercises. The experimental group performed submaximal aerobic exercise for 12 weeks (2 sessions of 45 minutes per week). The control group continued their daily activities during this period. At the end, the desired variables were measured again.After ensuring the normality of the data distribution, a mixed analysis of variance test (2x2 factorial design, time with two levels, and group as a between-subjects factor with two levels) was used.
Findings: The results showed that compared to the control group, the experimental group had significant improvements in static and dynamic balance, bimanual coordination, and flexibility at the post-test. (P<0/05).

The concept of imagery is to make an image of successful movement skill or a
relaxing image in mind with no body training and external experience. The aim of
the present study was to compare the effect of traditional and PETTLEP mental
imagery methods on static and dynamic balance. The statistical population
consisted of all female University of Tehran students who had general physical
education course (1) in the first educational semester in 1389-1390. 54
participants (Mean age 21.94±1.89 yrs) attended voluntary in this study. First, they
completed the Revised Movement Imagery Questionnaire (MIQ-R: Hall & Martin,
1997). Afterwards, pretest of static balance (Stork Balance Test) and dynamic
balance (Modified Bass Test of Dynamic Balance) were performed. Participants
were randomly assigned to three (n=18) groups (Physical training, Traditional
imagery and PETTLEP imagery) and trained for 12 weeks (20 min/week). Finally,
posttests of static and dynamic balance were performed under the same condition
as the pretest. Retention test was performed 24 hours later and transfer test 30
minutes after the retention test. One-way ANOVA test showed no significant
difference in static balance, dynamic balance and imagery ability scores in pretest
among groups (p>0.05). Although ANOVA with repeated measures illustrated that
although all three groups improved significantly in static and dynamic balance
(P0.05).
Overall, results showed PETTLEP imagery was an effective method but not
sufficiently efficient in dynamic balance.
