Case-Study 1

 

 
 
“M.F.” is a 50 year old, right-handed female, language teacher (ESL and German)

History:

On July 3, 2008, “M.F.” was involved in a physical altercation with member of her housing co-op. “M.F.” had her left hand pulled and twisted. In the process, she sustained a severe injury to the middle joint of the middle finger in the left hand (the proximal interphalangeal joint or PIP joint). She had no pain prior the injury, the pain starts after the accident until the PST therapy (7 months).


Physical Examination:

  • “M.F.” has developed a contracture of the proximal interphalangeal joint in the middle finger of her left hand. The contracture appears to be fixed, probably due to scar tissue or shortening of tissue.
  • The middle finger of her left hand is dysfunctional, in the sense that she is unable to make a good power grip and, when she does a fine motor grip (pressing the tip of the middle finger against the tip of the thumb); she is unable to adequately hold any object because of numbness. Use of the hand also leads to pain.
  • X-Rays showed a deformity in the middle finger, no fracture.


Previous Therapy:

Twenty physiotherapy treatments (ineffective)


Diagnosis:

Traumatic injury to the PIP joint of the left middle finger, causing a contracture.

“M.F.” reported that she felt a tingling in the injured joint when receiving the PST treatment. After two to three weeks of the PST treatment, she was pain free except for when she trained or overexerted the middle finger of her left hand. After the PST treatment, “M.F.” was able to use the left hand again.


Conclusion:

Six weeks after PST, the intensity of the pain decreased almost 100%, while the swelling and the warming decreased 100%.
