Prospective Sensor Controlled Compliance Analysis of Shoulder Abduction Splint After Rotator Cuff Repair

2017-02-17 13:23:21 | BioPortfolio


The postoperative shoulder rehabilitation in an abduction brace after rotator cuff reconstruction of the shoulder is crucial for a successful healing of the reconstruction.

In this study we want to analyse the abduction brace-wearing time using a electronic sensor, which is implanted in the abduction brace. The patient´s will be informed about the sensor after completion of the abduction brace rehabilitation 6 weeks postoperatively.


After arthroscopic reconstruction of a rotator cuff tear the healing depends on a tension free positioning of the reconstructed tendon. Therefore a abduction brace is administered routinely for 6 weeks. The re-rupture rate of rotator cuff reconstruction is about 30%. One of the reason may be mechanical overuse caused by non wearing of the abduction brace. From experience we suggest that the abduction brace wearing behaviour differs among patients. The patient´s wearing compliance has been evaluated by Silverio et al. with a questionary but never with a sensor. In this study we want to analyse the patient´s abduction brace wearing compliance by using an sensor, which is implanted in the abduction brace and monitors the wearing time, which reveals the objective wearing time.

The sensor is a certificated sensor, which measures temperature in °C every 15 min. If the abduction brace is worn by the patient the body temperature can be captured by the sensor. If the measured temperature is over 33°C the sensor capture the time period as a "worn" time. With this measurements the abduction brace wear time should be captured objectively. A similar kind of sensors were used to evaluate the wearing time of scoliosis-braces in patients with adolescent idiopathic scoliosis (Miller DJ eta al., Morton A et al., Takemitsu et al.) With a questionary the patients are asked of the wearing time before they will be informed about the implanted sensor. This answer represents the subjective wearing time.

The first endpoint of the study is the evaluation of the objective and subjective abduction wearing time. The second endpoint is the evaluation of the correlation between compliance and subjective outcome.

Medical and Biotech [MESH] Definitions

Compression of the rotator cuff tendons and subacromial bursa between the humeral head and structures that make up the coracoacromial arch and the humeral tuberosities. This condition is associated with subacromial bursitis and rotator cuff (largely supraspinatus) and bicipital tendon inflammation, with or without degenerative changes in the tendon. Pain that is most severe when the arm is abducted in an arc between 40 and 120 degrees, sometimes associated with tears in the rotator cuff, is the chief symptom. (From Jablonski's Dictionary of Syndromes and Eponymic Diseases, 2d ed)

The musculotendinous sheath formed by the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. These help stabilize the head of the HUMERUS in the glenoid fossa and allow for rotation of the SHOULDER JOINT about its longitudinal axis.

The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system.

A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.

An alternative to REFRACTIVE SURGICAL PROCEDURES. A therapeutic procedure for correcting REFRACTIVE ERRORS. It involves wearing CONTACT LENSES designed to force corrective changes to the curvature of the CORNEA that remain after the lenses are removed. The effect is temporary but is maintained by wearing the therapeutic lenses daily, usually during sleep.
