Interexaminer agreement for applied kinesiology manual muscle testing.

Two trials of the interexaminer reliability of Applied Kinesiology manual testing were conducted. On the first trial three clinicians, each with greater than ten years of experience with muscle testing procedures, tested 32 healthy individuals to estimate their agreement on the strength or weakness of right and left piriformis and right and left hamstring muscles. Significant agreement between examiners was found for piriformis muscles, but little significant agreement was noted when hamstrings were tested. In a second study, the same three examiners tested 53 subjects for strength or weakness of the pectoralis and tensor fascia lata muscles bilaterally. Significant interjudge agreement was found for pectoralis muscles, but no significant concordance could be found when the tensor fascia lata was examined.
