5. QST in patients with tendinopathy
2.4. Statistical analyses
The data of the thirteen measurements of QST in the injured athletes were compared
to the healthy controls. Since some of the QST outcomes are ordinal data and most
data were non-normally divided we used non-parametric tests (Mann Whitney U). The
descriptive data of the social demographic parameters are presented. Because of nonnormally
divided data the SCL-90 and POMS dimensions were analyzed using nonparametric
(Mann Whitney U) test to compare injured versus control athletes.
3. Results
3.1. Participants
The socio-demographic data are presented in Table 5-1; twelve PT patients and 20
control athletes were included in the study. All athletes were still training and or playing
matches. The outcome on the VISA-P differed significantly between patients (VISA-P
62, SD 17.97) and controls (VISA-P 99, SD 1.68). The median duration of symptoms
for the PT group was 30 months (range 6 - 120). The outcome of QST assessment is
presented in Table 5-2.

3.2. QST
In two of the thirteen QST parameters i.e. mechanical pain threshold and vibration
disappearance threshold injured athletes were significantly more sensitive for the
applied stimuli than for the control group (Table 5-2). None of the athletes showed signs
of dynamic mechanical allodynia (DMA). The room temperature during QST testing
was 23.7°C (SD 0.8).
