For Pryor, that meant total, transgressive frankness about racism, sex and pain: subjects on which, as a black American raised in a brothel by a violent father, he was well qualified to speak.
After obtaining information on the current pain, subjects complaining of headache and other pain were excluded.
In the distraction condition, identical procedures were followed, but during heat-capsaicin pain, subjects played a series of video games.
da Silva RA Jr, Arsenault AB, Gravel D, Larivière C, de Oliveira E Jr. Back muscle strength and fatigue in healthy and chronic low back pain subjects: a comparative study of 3 assessment protocols.
The primary aims of this study are to compare neck disability in masticatory myofascial pain subjects versus asymptomatic controls, and to evaluate the correlation between neck disability and muscle pain.
Fig. 2 Development of systolic BP (a), diastolic BP (b), heart rate (c) finger blood flow (d) and pain (e) throughout the stressful task and recovery period in chronic pain patients (chronic TTH, FMS and SNP) and episodic pain/no pain subjects (episodic TTH, migraine and controls).
The objective of the current study was to investigate whether any differences exist in the activation patterns of the gluteus maximus (GM), hamstring (HAM), contralateral erector spinae (CES), and ipsilateral erector spinae (IES) muscles during prone hip extension (PHE) between non-low back pain subjects who demonstrate specific "abnormal" lumbar spine motion patterns and those who do not.
Pain subjects presented with a higher mean BMI (30.4 kg/m) compared with No Pain subjects (27.5 kg/m) (p < 0.0001).
MEAP and systemic pain thresholds were inversely correlated in low back pain subjects.
Figure 1A shows algorithms' performance in linear discrimination between controls and pain subjects.
Bahat et al. [ 29] used a virtual reality motion assessment system to evaluate pain and no-pain subjects and reported reductions in both peak and average velocities for motions produced by pain subjects.
