1. Klaver-Krol, E.G. Neuromuscular functions in sportsmen and fibromyalgia patients: a surface EMG study in static and dynamic conditions.

Degree: Faculty of Behavioural, Management and Social Sciences, 2012, University of Twente

This thesis presents two studies, one involving sportsmen (sprinters versus endurance athletes) and one fibromyalgia patients (patients versus healthy controls). The studies have investigated muscular functions using a non-invasive method: surface electromyography (sEMG). In the sportsmen, differences were found between the muscles of sprinters and of endurance athletes that were in accordance with the composition of their muscle fibers. The findings also suggest differences between sprinters and endurance athletes in the neural regulatory strategies of the muscles. Fibromyalgia is an unexplained affliction characterized by widespread pain, especially in the muscles. In the fibromyalgia patients, disturbances were observed of the muscle membrane with excessive propagation velocities along the membranes. Surprisingly, the higher propagation velocities in fibromyalgia patients appeared to obscure the signs of fatigue in sEMG that would normally be apparent when applying prolonged exercises. Furthermore, a clear positive correlation was found between the degree of membrane disturbance and the extent of the somatic signs (the number of painful spots known as tender points) in the patients. The findings are discussed and compared with the literature. The sEMG method used in this study is innovative. In particular, the dynamic conditions of the experiments are of interest because these have been seldom applied, despite the fact that they reveal a clearer reflection of everyday situations when compared with the static conditions more usually employed. The method involves subjects exerting both short and prolonged efforts. Applying a prolonged effort allows one to observe fatigue processes in a muscle. Novel parameters are used in the sEMG analysis based on the velocities of the peaks (motor unit potentials) and their associated statistics. By applying these parameters, it becomes possible to extract more refined features from an sEMG. Advisors/Committee Members: Rasker, Hans J., Psychology, Health & Technology.

2. Zijlstra, Tjeerd Roelof. No pain, no gain. Measuring treatment effects in fybromyalgia.

Degree: Faculty of Behavioural, Management and Social Sciences, 2007, University of Twente

Fibromyalgia syndrome (FM) is a condition of chronic pain, fatigue and other symptoms without a known anatomical substrate. Until now, treatment is mostly unsatisfactory; empirical studies on pharmacological and non-pharmacological treatment strategies in FM are needed. Following an overview of FM and its treatment, two such trials are described in this thesis. The first one is a pre-randomised clinical trial of spa treatment in FM. A combination of thalassotherapy, physical exercise and patient education in a Tunisian spa resort improved FM symptoms and health-related quality of life. Differences between spa treatment (n = 58) and treatment-as-usual (n = 76) were statistically significant after 3 months, but not after 6 and 12 months. Cost-effectiveness analysis showed no significantly different costs in the spa and control group, except for the cost of spa treatment (€ 1,526). Quality of life was higher in the spa group: 0.04 Quality Adjusted Life Years (QALYs) based on the visual analogue scale for general health (p< 0.01). The incremental cost-utility ratio after 6 months of follow-up was € 1,311 / 0.04 = € 32,775 per QALY gained (95% confidence interval -375,000 to 273,000). The second study is a 6-week double-blind randomised controlled trial comparing venlafaxine 75 mg/day (n = 45) to placebo (n = 45). The results of the Fibromyalgia Impact Questionnaire (FIQ) suggested a positive effect. Primary outcome measures (McGill Pain Questionnaire and visual analogue painscales) improved by 10%. However, no statistically significant differences between venlafaxine and placebo were seen. The importance of placebo effects in many FM drug trials is discussed separately. The combined data from both trials were used to validate a Dutch translation of the FIQ, which showed sufficient reliability, construct validity and responsiveness to be recommended as an outcome measure in FM. The studies described in this thesis show that empirical studies in FM are feasible and determination of effects and effect sizes is possible.
