Primary goal:   to determine the validity of C1 transverse process (TVP) palpation compared to an imaging reference standard.

METHODS:   Radiopaque markers were affixed to the skin at the putative location of the C1 TVPs in 21 participants receiving APOM radiographs. The radiographic vertical distances from the marker to the C1 TVP, mastoid process, and C2 TVP were evaluated to determine palpatory accuracy.

RESULTS:   Interexaminer agreement for radiometric analysis was “excellent.” Stringent accuracy (marker placed ±4mm from the most lateral projection of the C1 TVP) = 57.1%; expansive accuracy (marker placed closer to contiguous structures) = 90.5%. Mean Absolute Deviation (MAD) = 4.34 (3.65, 5.03) mm; root-mean-squared error = 5.40mm.

The ability of a manipulative therapist to diagnose symptomatic cervical zygapophysial joint syndromes accurately was evaluated in a series of 20 patients. In 11 patients the presence, or absence, of a symptomatic joint was established by means of radiologically-controlled diagnostic nerve blocks. These patients were assessed by the manipulative therapist, without knowledge of the medical diagnosis. Another nine patients were first seen by the manipulative therapist whose diagnosis was then evaluated by means of diagnostic blocks.
