Brief Summary

A number of different therapeutic approaches to treat lateral epicondylitis have been tested partly in randomized trials, such as polidocanol sclerosing injections, botulinom toxin A injections, braces, surgery and topical NO patches. One study indicates that patients with lateral epicondylitis (lateral elbow tendinopathy) have poorer elbow proprioception in contrast to healthy controls (Juul-Kristensen B, et al., J Shoulder Elbow Surg 2008;17(1 Suppl):72S-81S.) Based on a suggested poorer elbow proprioception in lateral elbow tendinopathy, The investigators hypothesize that a dedicated proprioceptive intervention might be able to reduce pain and improve function. As such a RCT is planned with two intervention arms with proprioceptive training using the Flexi-Bar vibration device (www.flexi-bar.co.uk) +/- the XCO-Trainer (www.xco-trainer.co.uk) over twelve weeks.

Outcome Measures

Primary Outcomes (1)

  • Pain on a visual analogue scale (VAS 0-10)

    Pain on VAS (0=no pain at all, 10= worst pain imaginable) before and 12 weeks after the intervention.

    before and 12 weeks after

Secondary Outcomes (4)

  • DASH Score

    before and 12 weeks after

  • Grip strength (JAMAR)

    before and after 12 weeks

  • Vibration

    before and 12 weeks after

  • 2-point discrimination

    before and 12 weeks after the intervention

Study Arms (2)

Active control (Flexi-Bar only)

ACTIVE COMPARATOR

Flexi-Bar vibration training only over 12 weeks with three distinct exercises and 10min training twice daily

Device: Flexi-Bar vibration device only

Intervention Flexi-Bar + XCO-Trainer

EXPERIMENTAL

Combination intervention using vibration device Flexi-Bar and XCO-Trainer (oscillating mass witin a tube moved during running 40-60min/week suggested)

Device: Flexi-Bar + XCO-Trainer

Interventions

daily vibration training 10min twice

Also known as: vibration, Flexi bar
Active control (Flexi-Bar only)

XCO-Trainer is a way to overload the cardiovascular system and the core muscles during running. An oscillating mass inside the XCO-Trainer is activated when the XCO is propelled forward and backward with force. The movement of the mass triggers a series of responses from the runners' body. In addition Flexi-Bar vibration training as in the referred active comparator group

Also known as: XCO, XCO Trainer, Flexibar, vibration
Intervention Flexi-Bar + XCO-Trainer

Eligibility Criteria
