Effects of 24-wk Exergame Intervention on Physical Function under Single- and Dual-task Conditions in Fibromyalgia: A Randomized Controlled Trial

OBJECTIVE:

To evaluate the effects of 24 week exergame intervention in the physical fitness of women with fibromyalgia in both single and dual-task conditions.

DESIGN:

Single-blinded, randomized controlled trial.

SETTING:

University facilities.

PARTICIPANTS:

Fifty-five women with fibromyalgia, recruited from the local fibromyalgia association, were randomly assigned to one of the two groups: exercise group and control group.

INTERVENTION:

The exercise group completed 24-week of supervised and group-based exergame protocol, divided into two sessions of 60 min. The intervention was focused on mobility, postural control, upper and lower limbs coordination, aerobic fitness and strength.

MAIN OUTCOME MEASURES:

The strength of the upper limbs was measured using the arm curl test. The mobility skill was assessed through the timed-up and go test and the flexibility of both upper and lower limbs was measured using the back scratch and the sit and reach tests respectively.

RESULTS:

Fifty participants completed the study. In the single-task condition, exergame intervention led to significantly higher effects in the arm curl test (p=0.008), sit and reach test (p=0.033) and timed-up and go test (p=0.021). Moreover, under dual-task condition, exergames led to significant effects in all the physical fitness tests (arm curl test, timed-up and go test, back scratch test and sit and reach test) compared to the control group.

CONCLUSIONS:

Exergame is an effective tool to improve the physical fitness in women with fibromyalgia under single or dual task conditions.
