“R. P.” is a 52 year old, right handed, male, machinist (tool and dye).

History:

On December 25, 2006, “R. P.” was involved in a motor vehicle accident. He complained of pain on the right side of the low back after the accident. The pain did not resolve.


Physical Examination:

Inspection of the spine did not reveal any obvious scoliosis or kyphosis. His pelvis, however, was slightly tilted. The left hemi-pelvis was elevated by about ½ inch compared to the right. This pelvic asymmetry was even more evident during forward bending. The left hemi-pelvis over-rotated compared to the right. Palpation of the left sacroiliac joint caused pain. He was tender over the lumbar/sacral junction. Extension and lateral tilting over the left side also caused pain.


Previous Therapies:

  • Physiotherapy was ineffective


Diagnosis:

“R. P.” has a mechanical injury to the pelvis. The left hemi-pelvis is out of alignment, and he has more symptoms with pressure into the left sacroiliac joint. The pain probably refers across the low back.

Explanation of ratings: 
0 = six or more hours before the pain increases and disturbs function. 
1 = around 4 hours before the pain increases and disturbs function. 
2 = around 2 hours before the pain increases and disturbs function. 
3 = 20 min to 1 hour before the pain increases and disturbs function. 
4 = 5 min to 20 min before the pain increases and disturbs function. 
NA = not applicable


Conclusions:

  • Six months after PST, there were no change on the pain scales.
  • “R.P.” had improvements of 66% sleeping and 33% standing on the function scales.
