Sammanfattning
Purpose: To examine whether there are any changes in PainMatcher score, used as
measurment for nociseptive stimuli before, during and after high-intensity aerobic
activity.
Design: Single Subject Design (SSD).
Material: Twelve healthy, female, physiotherapy students. Ten participants completed
the study.
Method: Thirty minutes of high-intensity running, controlled for intensity (determined
by pre-testing) and duration. PainMatcher scores were recorded before, every 10th minute
during the intervention, and 15 minutes after the intervention. A repeated-measures
Huynh-Feldt corrected «General Linear Model» (GLM) using the 50 Pain-Matcher
scores was performed as well as post hoc Bonferroni-corrected pairwise comparisons
between measures.
Results: The analyses revealed a significant mean change in 50 of the PainMatcher
scores during intervention; «within-subjects effects» (F (3.989) =5.334, p<0.05).
Measure 4 (after 30 minutes) was significantly different (p<0.05) from all the other
measures except from measure 3 (after 20 minutes).
Conclusion: The PainMatcher scores (n=50) showed a significant change during the
intervention, with the highest scores after 20 and 30 minutes. The increased tolerance
in nine out of ten participants indicates a plausible exercise-induced hypoalgesia
which was possible to detect using a PainMatcher. PainMatcher might be as sensitive
to changes in tolerance as other instruments for measuring nociseptive stimuli.
