Pain induced by low-grade stress in patients with fibromyalgia and chronic shoulder/neck pain, relation to surface electromyography.

The mechanisms of pain causation in fibromyalgia (FMS) and chronic shoulder/neck pain (SNP) are still debated. We wanted to compare muscle activity and pain development during and after low-grade mental stress in FMS and SNP patients. Twenty-three women with FMS, 29 women with chronic SNP and 35 healthy women performed a stressful task lasting 60 min followed by a 30 min recovery period. We recorded surface electromyography over the trapezius, neck, temporalis and frontalis muscles. Subjects reported their pain at the corresponding locations together with the development of fatigue and perceived tension. Significant differences between FMS and SNP groups were not observed either for muscular or subjective responses. SNP patients and controls responded with more pain in the trapezius and neck regions than in the forehead, in contrast to FMS patients who had a more generalized pain response. Development of pain, tension and fatigue was not related to muscle activity for any group. We conclude that FMS and SNP patients have similar pain and electromyographic responses. The results suggest that similar pathophysiological mechanisms are involved although the responses are more generalised in FMS than in SNP patients. Muscular activity did not explain the pain which developed during the stressful task for either group. Pain lasted longer during recovery in both FMS and SNP patients compared to healthy controls, possibly a result of disease-related sensitisation in pain pathways.

Comparison of two physical exercise programs for the early intervention of pain in the neck, shoulders and lower back in female hospital staff.

The aim of the present study was to compare the effect of increased aerobic capacity versus muscle strength rehabilitation of female hospital staff with long-lasting musculoskeletal back pain. Seventy-nine women agreed to participate in the intervention study. After a medical examination, 65 individuals were assigned to one of three balanced groups: Endurance training (aerobic capacity promoting training: ET: n = 22), strength promotion exercise (SP: n = 24) or a control group (CON: n = 19). The active groups met twice a week for 60 minutes of exercise over 15 weeks. Aerobic capacity (VO2max) and musculoskeletal pain were measured immediately before (T1) and after the intervention period (T2). Aerobic capacity significantly increased in the ET group, whereas no change was observed in the SP group, and a significant reduction was found in the CON group from T1 to T2. Musculoskeletal pain was significantly reduced in both intervention groups, whereas minor changes were observed in the control group. Results from a 7-month follow-up (T3) survey confirmed the beneficial effects of interventions on musculoskeletal pain. In conclusion, improved aerobic capacity appeared not to be a necessary mechanism in musculoskeletal back pain reduction.

[Fall from high altitude].

BACKGROUND: It is controversial in which way the human body can tolerate mechanical stress and later develop sequelae after deceleration trauma. MATERIAL AND METHODS: A report on a 26-year-old male who survived a free fall of 28 metres from a building. RESULTS: It is accounted for an achieved velocity of 81 kph and accumulated energy of 21,000 Joule. The incident lead to multiple complicated fractures, nerve injuries and an acute head injury. The patient's cognitive function was restored after a few months, and he is satisfied with the outcome.

Neuroacanthocytosis--the variability of presenting symptoms in two siblings.

Neuroacanthocytosis is a progressive multisystem disease with a wide range of symptoms. The involuntary movements mainly include chorea and orofaciolingual dyskinesias. The descriptive name of the disease refers to the presence of abnormal erythrocytes in peripheral blood. Two siblings are presented. One young female had dystonia, self-mutilating behaviour, lip biting and eating difficulties. Her brother had repeated generalized epileptic seizures several years before developing choreatic movements and neuropsychiatric symptoms. Both had clinical signs of sensorimotor axonal polyneuropathy. Fresh blood smears in each patient contained between 15 and 20% acanthocytes compared to less than 2% in normal controls. Neuroacanthocytosis must be kept in mind in young adult patients without heredity for Huntington's disease and the diagnosis is easily confirmed when making a fresh blood smear.
