History:

The patient, a 40 year old man, had pain in his left knee for about 10 years. A doctor diagnosed his problem to be caused by thinning of the capsule in his knee joint. Since 7 years back, he could not bend his knee completely. Besides, he also felt pain in this problem area, on and off, for the past 10 years. He was treated with Short Wave diathermy at the hospital for 3 sessions prior to the start of Sonotron Therapy and was on pain killing drugs.


RESULT AFTER 1ST THERAPY SESSION ON MAY 17, 1995.

Prior to the Sonotron therapy, the patient had taken his regular dose of his pain killing drug and was given a session of Short Wave diathermy. Despite the situation, he registered a pain score of 8 out of 10 when he bent his knee with the support of both hands. He was able to bend to a maximum of 90 degrees. 

Immediately after the Sonotron treatment, he was able to bend his L-knee completely with only one hand to support his movement with an improvement of his pain score to 6 out of 10.


RESULT AFTER 2ND THERAPY SESSION ON MAY 18, 1995.

Just prior to treatment, he felt less pain than the day before, when he bent his L-knee. He reported a pain score of only 4 out of 10 at his L-knee. He also observed that he was able to bend more. The angle of maximum bending, with the support of only one hand, was measured to be 50 degrees, 10 degrees above the angle of complete flexion of his knee.

Immediately after treatment, he registered a score of 2 out of 10, an improvement in his pain on bending.  He was also able to bend his knee completely without any support of either hand.


RESULT AFTER 3RD THERAPY SESSION ON MAY 19, 1995.

Prior to Sonotron Therapy, he reported a pain score of  4 out of 10 in his L-knee. He also observed that he was able to bend completely without support.

After therapy, he reported a pain score of only 2 out of 10 in his L-knee when he bent it. He commented that Sonotron was able to reduce his pain very quickly and effectively and he was very happy with the treatment. 

RESULT AFTER 4TH THERAPY SESSION ON MAY 20, 1995.

In the evening of the day before, he exerted himself by taking part in sporting activities. He reported that his pain had increased to a level of  5 out of 10 in his L-knee. He also observed that he was still able to bend completely without support. He was advised to take care and not to overstrain himself again, if possible.

After therapy, he reported a pain score of 1 out of 10 in his L-knee when he bent it. He commented that the pain had reduced drastically.

"Before 17/5/95 I had short wave for 2 sessions, the effect was slow. After the treatment from Sonotron, I feel the effect is faster and better. The pain reduced tremendously and I can bend better without any support. The effect from medication is slow."
