Effects of progressive muscle relaxation therapy with home exercise on pain, fatigue, and stress in subjects with fibromyalgia syndrome: A pilot randomized controlled trial.

BACKGROUND

Fibromyalgia is accompanied by symptoms of fatigue, depression, sleep disorders, and physical and mental stress [1]. It is a difficult-to-treat disorder because its exact causes are unknown.

OBJECTIVE

This study aimed to examine the effect of progressive muscle relaxation therapy (PMRT) on pain, fatigue, and stress in patients with fibromyalgia syndrome.

METHODS

Thirty-seven patients with fibromyalgia syndrome (age: 20-65 years) were randomly allocated to the PMRT group (n1= 18, 2 men and 16 women) or non-PMRT group (n2= 19, 2 men and 17 women). The PMRT group received PMRT twice a week for 8 weeks and the non-PMRT group received conventional physical therapies such as electro-stimulation and heat therapies during this period. The outcome was evaluated before and after 8 week sofintervention using the Visual Analogue Scale, Multidimensional Assessment of Fatigue, Perceived Stress Scale, and measurement of the blood pressure and pulse rate.

RESULTS

Pain and fatigue significantly decreased in the PMRT group compared with the non-PMRT group (both P< 0.001). In addition, perceived stress (P< 0.001), systolic blood pressure (P< 0.001), diastolic blood pressure (P< 0.05), and pulse rate (P< 0.001) significantly decreased in the PMRT group compared with the non-PMRT group.

CONCLUSIONS

The findings indicate that progressive muscle relaxation therapy is a viable rehabilitative therapy for pain, fatigue, and stress symptoms in patients with fibromyalgia syndrome.
