The Effects of a Wrist Extensors Exercise With Blood Flow Restriction (BFR) in Lateral Elbow Tendinopathy.
- Conditions
- Lateral Epicondylitis
- Registration Number
- NCT05919914
- Lead Sponsor
- University of West Attica
- Brief 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

- Primary Outcome Measures
Name Time Method Pressure pain threshold Baseline and 30 minutes Changes between pre- and post- intervention in Pressure Pain Threshold will be measured using bilateral sites on lateral epicondyle, cervical spine and tibialis anterior. The COMPACT DIGITAL ALGOMETER CAPACITIES TO: 100 lbf / 50 kgf / 500 N, will be used by an independent assessor. The assessor will be blinded to participants' group.
- Secondary Outcome Measures
Name Time Method Pain free grip strength (PFGS) Baseline and 30 minutes 'Jamar' hand dynamometer was used, calculating the mean value (kilograms) of 3 efforts, separated by 30-second rest intervals with participants lying in supine position and the elbow fully extended
