Summary

A randomized cross-over trial comparing the immediate effects of a wrist extensor exercise with and without blood flow restriction (BFR) on pain perception in patients with lateral elbow tendinopathy (LET).

Detailed description

Patients with LET will participate in the study performing an exercise with and without blood flow restriction (BFR) in a randomized order (two occasions). A target of 20 patients for enrollment has been set for 80% power, p\<0.05 (Effect size= 1). Two interventions will be used lasting 40 minutes each. Intervention: A wrist extension exercise (concentric-eccentric) with Blood Flow Restriction (30-15-15-15 reps). Exercises will be performed using dumbbells according to a pain monitoring approach (\<2/10 in numerical pain rating scale). Control Group: A wrist extension exercise (concentric-eccentric) without Blood Flow Restriction (30-15-15-15 reps). Exercises will be performed using dumbbells according to a pain monitoring approach (\<2/10 in numerical pain rating scale). Primary outcomes: pressure pain thresholds lateral epicondyle, cervical spine and tibialis anterior (bilateral). Secondary outcome: pain free grip strength

Conditions

• Lateral Epicondylitis

Interventions

Type	Name	Description
OTHER	Exercise with Blood Flow Restriction (BFR)	Wrist extensor exercise (concentric - eccentric) with BFR. BFR involves the reduction of blood flow to working skeletal muscle by applying a flexible cuff to the most proximal portions of a person's arms or legs that results in decreased arterial flow to the exercising muscle and occluded venous return back to the central circulation.
OTHER	Exercise without Blood Flow Restriction (BFR)	Wrist extensor exercise (concentric - eccentric)
