Effects of the Tyler Twist Versus Eccentric Exercises

1. juni 2026 oppdatert av: Riphah International University

Effects of the Tyler Twist Versus Eccentric Exercises in Patients With Lateral Epicondylagia

This study aims to compare the effects of the Tyler Twist exercise versus traditional eccentric exercises on pain, grip strength, and functional outcomes in patients diagnosed with lateral epicondylalgia. The primary objective is to determine which intervention offers greater improvement in clinical symptoms and overall function over a defined treatment period.

Detaljert beskrivelse

Conservative management is typically the first line of treatment, with eccentric exercises widely recognized for their effectiveness in promoting tendon healing and reducing pain. The "Tyler Twist," exercise is a variation using the TheraBand FlexBar, that has emerged as a superior potential alternative, that combines both eccentric and concentric loading in a functional and controlled way. However, direct comparative evidence between the Tyler Twist and conventional eccentric exercises has remained limited.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Tyler Twist Exercises
The Tyler Twist is a specific eccentric exercise using the TheraBand FlexBar, designed to target the extensor carpi radialis brevis (ECRB), which is primarily involved in lateral epicondylalgia.
Annen: Tyler Twist Exercises
  • Position:
  • The patient holds the FlexBar in both hands.
  • The affected arm is placed in front with the elbow extended and wrist in slight extension.
  • The unaffected hand grips the other end of the FlexBar.

  • Twisting Motion:

    1. The patient uses the unaffected hand to twist the FlexBar into a taut position while the affected hand resists the motion (eccentric loading).
    2. Once the FlexBar is twisted, the patient extends the arms in front and slowly untwists the bar with the affected wrist, creating a controlled eccentric contraction.
    3. Emphasis is placed on slow, controlled movement (2-3 seconds for untwist).
    4. 3 sets of 15 repetitions, once daily.
    5. Progress to higher resistance FlexBars as tolerated (e.g., from red to green to blue).
    6. Supervision during clinical visits (twice per week), rest is home-based
Aktiv komparator: Traditional Eccentric Wrist Extensor Exercises
This protocol involves eccentric strengthening of the wrist extensor muscles (primarily ECRB)using a dumbbell (1-2 kg) or wrist cuff weight.
Annen: Traditional Eccentric Wrist Extensor Exercises
  • Position:
  • Patient seated with the forearm resting on a table, palm facing down, wrist hanging off the edge.
  • Elbow flexed to ~90 degrees.

  • Eccentric Movement:

    0. The patient uses the unaffected hand to assist the affected wrist into extension (starting position).

    1. The affected wrist then slowly lowers the weight into flexion (eccentric contraction).
    2. The cycle is repeated, focusing on slow movement (2-4 seconds lowering phase).
    3. 3 sets of 10-15 reps, once daily.
    4. Weight increased progressively based on pain-free performance.
    5. Supervised sessions 2x/week; home exercise on other days

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Numeric pain rate scale (NPRS) for pain
Tidsramme: 6 weeks
To determine the degree of pain that the patient will report, the Numeric Pain Rating Scale (NPRS) will be utilized. This scale consists of 11 points ranging from 0-10, where zero indicates no pain, five represents moderate pain intensity, and ten signifies severe pain intensity
6 weeks
Handheld dynamometer for grip strength:
Tidsramme: 6 weeks
For pain-free grip strength assessment, the patient's arm is positioned comfortably with the shoulder adducted and neutrally rotated, the elbow flexed to 90 degrees.20, the forearm in a neutral position, and the wrist in slight extension and ulnar deviation. The patient is instructed to squeeze as tightly as possible for 3-5 seconds, with multiple trials and an average of three repetitions recorded. A brief pause is provided between trials to prevent muscle fatigue. Hand-held dynamometers have been shown to have excellent internal validity and reliability, with reported values of 0.31-0.69 in the upper extremities

Patient-Rated Tennis Elbow Evaluation (PRTEE) for functional disability
Tidsramme: 6 weeks
The PRTEE questionnaire is one of the most widely-used outcome measures that appreciates elbow
