Stretching
Conditions
Brief summary
Stretching is frequently used in clinical practice to manage musculoskeletal discomfort and to prevent sports injuries. It is not known if stretching affects pain sensitivity. The purpose of this study is to investigate if a 4 week daily stretching protocol alters pain sensitivity. The investigators hypothesize that stretching reduces pain sensitivity.

Secondary
| Measure | Time frame |
|---|---|
| Change from baseline in PPT at the counter lateral calf | Baseline and 4 weeks |
| Change from baseline in PPT at the ipsilateral arm | baseline and 4 weeks |
