4.3. Evaluation of the questionnaire
4.3.1. Test results of the dependent variables
The primary dependent variables of this study are quality of life and pain.
Disabilities encountered in everyday life were evaluated based on the number of
statements marked on the Roland-Morris Disability Questionnaire. A pain scale from
0-10 was used for pain assessment.
From the seven questionnaires handed in during the observation period by each of
the test persons, a mean value was calculated. Thus, we have a value for the quality
of life and a value for the pain intensity for each observation period.
There are four observation periods for the 14 test persons:
1. without therapy – reference week (RW)
2. after the first therapy (PT1W)
3. after the second therapy (PT2W)
4. after the third therapy (PT3W)
For each of the observation periods,
the mean, minimum and maximum
values were calculated. (see graphs
4G and 4H)
The mean values of each dependent
variable (pain and disability in
everyday life) show a significant
reduction.

When assessing the progress of each

becomes evident that the results of
only one test person (TP13) show a
very distinct development; in her case,
