Stretching and Pain Sensitivity

Not Applicable

Completed

• Conditions: Stretching
• Interventions: Other: Calf muscle stretching

• Registration Number: NCT02027766
• Lead Sponsor: Marius Henriksen

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.

Arm && Interventions

Group	Intervention	Description
Stretching	Calf muscle stretching	Daily stretching of the calf (dominant side; defined as leg used to kick a ball). 2 stretching exercises are performed daily: 1) stretching of the soleus muscle; 2) stretching of the gastrocnemius muscle.

Primary Outcome Measures

Name	Time	Method
Change from baseline in pressure pain threshold (PPT) at the ipsilateral (same side as being stretched) calf assessed by a cuff pressure algometer	Baseline and after 4 weeks

Secondary Outcome Measures

Name	Time	Method
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
Change from baseline in temporal summation of pressure pain at both calfs and ipsilateral arm.	Baseline and after 4 weeks
