The level of evidence for PMPs varied across different test procedures in different types of PJP .
H and -held pressure algometry is the only test procedure that showed moderate positive evidence of intrarater reliability , agreement , and responsiveness , simultaneously , when it was investigated in patients with chronic knee osteoarthritis .
BACKGROUND Test procedures that were developed to assess somatosensory abnormalities should possess optimal psychometric properties ( PMPs ) to be used in clinical practice .
The aim of this systematic review was to evaluate the literature to assess the level of evidence for PMPs of test procedures investigated in individuals with peripheral joint pain ( PJP ) .
Mental motor imagery and chronic pain: the foot laterality task.
Several lines of evidence suggest that mental motor imagery is subserved by the same cognitive operations and brain structures that underlie action . Additionally , motor imagery is informed by the anticipated sensory consequences of action , including pain . We reasoned that motor imagery could provide a useful measure of  chronic leg or foot pain . Forty subjects with leg pain ( 19 bilateral , 11 right , and 10 left leg pain ) , 42 subjects with chronic pain not involving the legs , and 38 controls were shown 12 different line drawings of the right or left foot and asked to indicate which foot was depicted . Previous work suggests that subjects perform this task by mentally rotating their foot to match the visually presented stimulus . All groups of subjects were slower and less accurate with stimuli that required a greater degree of mental rotation of their foot . Subjects with leg pain were both slower and less accurate than normal and pain control subjects in responding to drawings of a painful extremity . Furthermore , subjects with leg pain exhibited a significantly greater decrement in performance for stimuli that required larger amplitude mental rotations . These data suggest that motor imagery may provide important insights into the nature of the pain experience
