In this cohort study, dynamic trunk extensor performance was studied as a predictor of permanent work disability due to back disorders. As part of the comprehensive Mini-Finland Health Survey in 1978-80, the back muscle performance of 535 persons (267 men, 268 women) was measured using standardized repetitive arch-up and sit-up tests. At baseline, the participants were between 30 and 64 years of a ...

We examined the associations between sociodemographic, pain and health-related factors and combinations of active and passive strategies in a general population random sample of 1131 adults. Individuals reporting neck ...

The study was performed to investigate the relationship between perceived muscle tension and electromyographic hyperactivity and to what extent electromyographic (EMG) hyperactivity relates to personality traits in fibromyalgics. Thirty-six females with fibromyalgia performed isokinetic maximal forward flexions of the shoulder combined with surface EMG recordings of the trapezius and infraspinatus ...

The aim of this study was to determine the relationship between ankle dorsiflexor strength and performances on several walking tests and to determine the effect of ankle-foot orthosis (AFO) use on walking tests. The following tests were used: 10-metre walking test (with and without three stairs), a complex walking task (6-minute walk with cognitive loading) and a subjective evaluation (SIP68 mobil ...

Test-retest reliability is important for long-term follow-up; however, data on the reliability of isokinetic dynamometry of the shoulder are scarce. Twenty subjects (50% male) were measured; 10 with asymmetrical use of the arms (mean age 27 years) and 10 used their arms symmetrically (mean age 32 years). A Biodex(r) dynamometer (Multi joint system 2) was used. Abduction/adduction and external/inte ...
