About this study

Official title: TenTed-Postoperative Biceps Strength and Electromyographic Activity After Proximal Biceps Tenotomy Versus Tenodesis in Patients With Arthroscopic Rotator Cuff Tear Repair

The most important functions of the biceps brachii muscle are flexion and supination of the elbow. Patients with a partial or complete rotator cuff tear often suffer a lesion of the long head of the biceps tendon (LHBT). The two most common surgical treatments options are tenotomy or tenodesis. This study is to assess the Supination Strength Index (SSI) (the operated side in relation to the healthy side) after proximal biceps tenotomy versus tenodesis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Measurement of Muscle strength using a dynamometerDiagnostic test

    Muscle strength will be measured in the elbow bilaterally using a dynamometer (Biodex System 4 Pro: Biodex Medical Systems, Shirley, NY, USA). Supination tests will be performed with the forearm in neutral position, 60° pronation and 60° supination. The elbow will be in 90° flexion, and the shoulder in 45° flexion. Constant pressure is applied to lever of device for 3 to 5 seconds. Maximum torque will be recorded automatically. For each position, three repetitions of 3s (to 5s) contractions will be performed with a break of 15 (or 30s) between the repetitions. There will be an additional break of 2 minutes between measurements of the supination strength in the different positions. This parameter will be analysed regarding asymmetry between both limbs.

    Isometric endurance of forearm supination will be measured in neutral forearm. Flexion tests will be carried in the same setting as for supination. Flexion tests will be performed with the elbow in 90, 45 and 0° of flexion.

  • Range of motion clinical measurement (shoulder and elbow)Diagnostic test

    The range of motion parameters (degree) of both shoulders and elbows will be documented. The circumference of the arm will be measured on the line between the medial acromion and the cubital fossa at 1/3 from the cubital fossa

  • Electromyography (EMG)Diagnostic test

    Electromyographic (EMG) data will be collected using a wireless EMG system (myon AG, Schwarzenberg, Switzerland). Surface electrodes will be placed bilaterally on biceps and triceps following the guidelines of the SENIAM project (Surface ElectroMyoGraphy for the Non-Invasive Assessment of Muscles)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Supination Strength Index SSI

    comparison of the Supination Strength Index SSI (the operated side in relation to the healthy side). It is calculated by dividing the strength on the operated side by the strength on the healthy side.

    Measured: at Baseline

Secondary outcomes (6)
  1. patient's pain visual analog scale Score (VAS)

    patient's pain visual analog scale score (VAS): 100-mm horizontal line on which the patient's pain intensity is represented by a point between the extremes of "no pain at all" and "worst pain imaginable

    Measured: at Baseline

  2. American Shoulder and Elbow Surgeons (ASES) Score

    The ASES questionnaire is composed of both a physician-rated component and a patient-reported component. The patient questions focus on joint pain, instability, and activities of daily living. Calculation of the ASES score is a complicated process. The final pain score is calculated via an independent formula, while the raw score from the functional questions is multiplied by a coefficient to get the final score for the functional questions. The pain and functional portions are then summed to obtain the final ASES score with higher scores indicating better outcomes

    Measured: at Baseline

  3. Constant Score

    This scoring system consists of four variables that are used to assess the function of the shoulder. The right and left shoulders are assessed separately.

    The subjective variables are pain and activities of daily living (ADL) (sleep, work, recreation / sport) which give a total of 35 points. The objective variables are range of motion and strength which give a total of 65 points. The test is divided into four subscales: pain (15 points), activities of daily living (20 points), strength (25 points) and range of motion: forward elevation, external rotation, abduction and internal rotation of the shoulder (40 points). The higher the score, the higher the quality of the function.

    Measured: at Baseline

  4. Long head of Biceps Score (LHB-Score)

    The LHB score (maximum 100 points) described by Scheibel et al. evaluates the qualities ''biceps pain and muscle cramps'' (maximum 50 points), ''cosmesis" (maximum 30 points) and ''flexion strength at the elbow'' (maximum 20 points)

    Measured: at Baseline

  5. muscle activation determined from electromyographic (EMG) data

    The level of muscle activation of the biceps during forearm supination will be expressed as percentage of the peak muscle activation during elbow flexion and compared between the limbs of each patient. The mean frequency of the muscle activation will be calculated using a Fast Fourier Transform in 1s windows. Fatigue will be determined as the change in the mean frequency from the beginning of the endurance task to the end of the endurance task

    Measured: at Baseline

  6. supination muscle strength

    Isometric endurance of forearm supination will be measured in neutral forearm. Participants will be asked to maximally supinate their forearm for as long as possible. Endurance will be quantified as the elapsed time until the patient stops the measurement due to fatigue.

    Measured: at Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Biceps Tendon Lesion, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Supination Strength Index SSI (time frame: at Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Dec 2022.
