  Purpose

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.

Further study details as provided by Hannover Medical School:

Primary Outcome Measures:
  • Pain on a visual analogue scale (VAS 0-10) [ Time Frame: before and 12 weeks after ]
    Pain on VAS (0=no pain at all, 10= worst pain imaginable) before and 12 weeks after the intervention.


Secondary Outcome Measures:
  • DASH Score [ Time Frame: before and 12 weeks after ]
    DASH score (0=no impairment, 100=severe impairment) of daily activities

  • Grip strength (JAMAR) [ Time Frame: before and after 12 weeks ]
    Grip strength (JAMAR) in two elbow positions (0° flexion, 90° flexion) before and after 12 weeks of intervention

  • Vibration [ Time Frame: before and 12 weeks after ]
    Vibration using a 128Hz tuning fork before and 12 weeks after the intervention

  • 2-point discrimination [ Time Frame: before and 12 weeks after the intervention ]
    2-point discrimination (mm) before and after the intervention and the finger tips


Estimated Enrollment: 70
Study Start Date: January 2011
Estimated Study Completion Date: September 2011
Estimated Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Active control (Flexi-Bar only)
Flexi-Bar vibration training only over 12 weeks with three distinct exercises and 10min training twice daily
Device: Flexi-Bar vibration device only
daily vibration training 10min twice
Other Names:
  • vibration
  • Flexi bar
Experimental: Intervention Flexi-Bar + XCO-Trainer
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

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

Other Names:
  • XCO
  • XCO Trainer
  • Flexibar
  • vibration

Detailed Description:

The investigators sought to evaluate the clinical effects of either a vibration training using the Flexi-Bar vibration device (www.flexi-bar.co.uk) +/- the XCO-Trainer (www.xco-trainer.co.uk) in a randomized trial among patients suffering lateral elbow tendinopathy (lateral epicondylitis).

Primary outcome measure of this clinical trial is pain on a visual analogue scale (VAS 0-10) before and after 12 weeks of training.

Secondary outcome parameters involve DASH score before and after, grip strength (JAMAR), vibration and two-point discrimination (mm).
