Is there an interaction between self-rated health and medication with analgesics and hypnotics in the prediction of disability pension?
Disability pension among middle-aged men was associated with self-rated health as well as medication and clear evidence of synergism between the two factors was found, while there were no indications of medication acting as a causal link between poor SRH and disability pension. Several mechanisms may contribute to the findings, but the information gained may be used as means to identify those at risk for disability pension.
Although the interobserver reliability of the manually assessed ADIM was high, the concurrent and discriminative validity were both low for examining the preferential activity of the deep abdominal muscles. Neither the manually assessed ADIM nor the ultrasound testing discriminated between participants with LBP and healthy subjects regarding preferential activity of the transversus muscle as this ability/inability was also present in healthy subjects.
