This paper reports on the three-dimensional loads measured during chiropractic treatments delivered during low back spinal procedures. A three dimensional force transducer was placed between the doctors hand and the patient while delivering the treatment. Two doctors have delivered treatments to a total of five subjects on two consecutive days. A laptop computer was used to collect data using labview software and Keithly instruments PCMCIA card. The data was analyzed using Mathcad software to determine the magnitudes of the forces delivered. The results show three-dimensional loads are applied by the doctor at the doctor’s hand-patient interface. The compressive forces reached as high as 450 Newtons, and the shear forces have reached as high as 150 Newtons. The moments have reached as high as 4Nm. This information is valuable in further understanding the effects of these loads on the spine.
