Brief Summary

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system. MS, typical presents with progression of clinical symptoms which mainly include motor and cognitive impairment, as well as reduction of patients' quality of life. Exercise is an effective approach in the management of the symptoms in people with progressive MS. Previous studies in healthy and in people with MS, reported a close relationship between cognitive functions and upper limb performance. Since patients with progressive MS facing difficulties with performing complex exercises due to cognitive dysfunctions and given the close relationship between cognitive functions and manual dexterity, a reasonable question arises whether a type of upper limbs exercises with less cognitive demands will improve the information processing speed in people with progressive MS. The aim of the current study is to investigate the effects of in-phase bilateral upper limbs exercises on the information processing speed, in patients with progressive MS, given that in-phase bilateral movements needs less attentional load than the other types of bilateral coordination. The intervention protocol lasted for 12 consecutive weeks (30-60 minutes /session x 3 sessions/week) and included in-phase bilateral exercises of the upper limbs, adapted to different sports activities and to functional training. Results from the statistical analysis indicated improvement of the experimental group compared to the control group, on the information processing speed alongside with improvement of motor skills.

Outcome Measures

Primary Outcomes (1)

  • Symbol Digit Modalities Test

    It is a commonly used test in pwMS, which measures processing speed as well as motor speed. The investigators employed the oral form of the test, in which participants were provided with the test sheet with nine symbols, each paired with a number on top of the page, defined as the "key". For example, the symbol "O" is matched with the number "6", so the correct response would be "six". The rest of the page consists of a randomized, sequential variety of these symbols. Participants are asked to verbally respond with the number that corresponds with each symbol. During the test, the participant is given two minutes to orally match symbols with digits as quickly as possible. The score is obtained by subtracting the number of errors from the number of items completed. To account for practice effects, the investigators created six different tests, as many as our assessment points, in which the order of the symbols and the numbers of the "key" were rearranged

EXPERIMENTAL

The exercise program of the experimental group consisted of exercises based on in-phase bilateral movements of the upper and lower limbs, which they were adapted to different sport activities and to fitness functional exercises. The specific exercise program was organized in a group circuit training, performed simultaneously on each session from all the participants of the experimental group, considering the MS exercise recommendations. Specifically, the program included sports activities of basic technical skills of basketball (e.g., different types of passing, catching and throwing the ball) and volleyball (e.g., different types of passing and receiving the ball), whereas the fitness exercises included the diagonal movements from proprioceptive neuromuscular facilitation technique, by the use of a resistance bands.

Behavioral: In-phase Bilateral Exercise

Controls

ACTIVE COMPARATOR

The participants of the active control group, underwent an exercise program based on conventional exercises, such as strengthening of the major muscle groups of the trunk, resistance exercises for the upper and lower limbs and body weight support treadmill exercise. All participants of the active control group performed the specific types of exercises individually, as opposed with the experimental group which was organized as a group training. Controls performed the specific type exercises once a week, for 12 consecutive weeks.

Behavioral: Conservative exercises

Interventions

The exercise program of the experimental group consisted of exercises based on in-phase bilateral movements of the upper and lower limbs, which were adapted to different sport activities and to fitness functional exercises. The participants of experimental group performed the specific type exercises three times per week, for 12 consecutive weeks.

IBPMS

The participants of the active control group, underwent an exercise program based on conventional exercises, such as strengthening of the major muscle groups of the trunk, resistance exercises for the upper and lower limbs and body weight support treadmill exercise.
