This may result from excessive loading, awkward postures, insufficient rest, or task repetition.
As concerns group Inv-first, no significant postural effect was detected for either the Upright or Inverted display, which would imply that visual information first presented in the Inverted display, although insufficient to contaminate observers' posture, provoked a stabilisation reaction which prevented contagion by the subsequent Upright stimulus.
In one patient (S2), the quality of the Doppler velocity spectrum in the upright posture was insufficient, and in the standing position, one patient (S5) developed serious orthostatic complaints and could, therefore, not complete three runs, and these data were excluded from the analysis.
Because prolonged sitting, static posture, and insufficient back support were positively associated with both neck pain and low-back problems among teachers [ 14], we can assume that these specific characteristics of teachers' occupational PA may induce strain and therefore decrease their perceived physical and mental health [ 7- 9, 11].
Of these, one [ 52] provided insufficient description of the postures for valid comparison stating only that there were "six yoga positions".
The opposite directions of the internal moment and trunk motion in the externally induced stop while pushing at shoulder height may indicate insufficient active control of trunk posture.
Although insufficient to cause abnormal carpal posture or collapse on static radiographs, an isolated injury to the scapholunate interosseous ligament may be the harbinger of a relentless progression to abnormal joint mechanics, cartilage wear, and degenerative change.
Usual culprits are lack of regular meals, insufficient (or too much) sleep, bad posture, household cleaners or certain perfumes, smoke, loud noise, bright lights, strobes, storms, harsh sunlight or even cold wind.
The following risk factors are discussed: workplace adjustment and body posture, static workload and insufficient breaks, high workload and work stress.
According to the review on work-relatedness of biomechanical factors, published by the National Institute of Occupational Science and Health (NIOSH) [ 10], there was insufficient epidemiological evidence that non-neutral wrist postures are an independent risk factor for CTS.
