| Volvo ran clinical trials on the system
for 3 months using 108 patient employees in 3 groups, with a median age of
44.1 years, 77% male. Group #1 was the control group with no uses of
the system, group #2, once a day and group #3 was twice a day treatments.
The result was that a estimated 7 - 8 days of work per year per patient could be saved by using the system |

| In 1992, systems were placed at 22 of
the city's workplaces for a period of 3 months. These were utilized
by a total of 144 people. Each workplace had a contact
person/instructor/trainer. A total of 115 people (81%) from 19 workplaces responded to all of the questions in the study. Of these, 60 used the system for at least 2 of the 3 months. The results of the study indicated both neck/shoulder and lower back improvements, These subjective changes included both pain intensity and problem frequency. Based on previous case descriptions, a decrease in both pain and frequency were observed |

| A 1.5 year study was performed,
beginning December 1996 studying the effects of the system on
osteoarthritis. Initially, 20 people were in the control group and
20 in the test group. However, 8 withdrew or did not complete the
study in each group. Each patient was given a thorough examination
for strength, endurance, balance, mobility, crepitations and
palpation-soreness around the knee joint. In addition, they
completed a questionnaire concerning their pre-existing conditions. The results are based on an average value calculated on the 24 people that completed the entire study in both groups. The measures were taken from the Visual Analogue Scale and from the C. Ekdahls instrument which measures strength.

| In 1999, 30 patients (16 - 49 years
old) with 10 prolapsed intervertebral disc; 10 lumbar spondylosis and 10
muscle strain/sprain (hamstring pull) were subjects. Patients were
to mark perceived pain and stiffness on a VAS prior to and after
treatments. SLR (Staright Leg-Raising) was also measured in the same
manner. The results were: Mean SLR was 6 degrees pre and 42.7 post treatment or nearly 8 times the movement; Mean Visual Analog Rating in Centimeters was 6.8 pre and 2.0 post or 1/3rd the perceived pain. |
