# Rotator Cuff Tears in Hemiplegic Shoulder

**Official Title:** Observational Study to Evaluate the Prevalence of Rotator Cuff Tears in Hemiplegic Shoulders

**NCT ID:** [NCT00998868](https://clinicaltrials.gov/study/NCT00998868)

## Key Facts

- **Status:** COMPLETED
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 51
- **Lead Sponsor:** Seoul National University Hospital
- **Conditions:** Hemiplegia
- **Start Date:** 2008-01
- **Completion Date:** 2010-08
- **CT.gov Last Update:** 2011-09-30

## Brief Summary

The purpose of the study is to evaluate the prevalence of rotator cuff tears in the shoulders of hemiplegic patients of different severity.

## Detailed Description

Rotator cuff tears are often suspected to contribute hemiplegic shoulder pain. However, it is controversial whether their incidence increases in hemiplegia. Based on the postulate that muscle weakness in hemiplegia predisposes rotator cuff injury due to biomechanical failure, this study aims to investigate whether the rotator cuff tears are associated with the muscle strength of the shoulder by observing hemiplegic shoulders of varying degree of paresis.

## Eligibility

- **Minimum age:** 20 Years
- **Maximum age:** 90 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* hemiplegia; unilateral weakness of sudden onset
* secondary to strokes or other brain lesions
* compatible with brain lesions confirmed by imaging studies

Exclusion Criteria:

* bilateral weakness
* any history of intensive trauma of the shoulder, reported
* preexisting musculoskeletal disorder of the shoulder
```

## Arms

- **hemiplegia** — patients with hemiplegia, without other musculoskeletal disorders of the shoulder

## Primary Outcomes

- **Rotator Cuff Tear of the Hemiplegic Shoulder, Confirmed by Ultrasonography** _(time frame: within one month after enrollment)_ — All patients underwent ultrasonography (USG) for the both, affected and unaffected, shoulders. USG routinely examined biceps, subscapularis, supraspinatus, and infraspinatus tendons as for the partial or complete tears, calcifications, bony irregularity and bursal swellings.

## Secondary Outcomes

- **Rotator Cuff Tear of the Unaffected Shoulder, Confirmed by Ultrasonography** _(time frame: within one month after enrollment)_
- **Subluxation of the Glenohumeral Joint, Confirmed by Physical Examination** _(time frame: within one month after enrollment)_
- **Muscle Strength, Measured by Physical Examination, Per Medical Research Council Muscle Strength Grading System** _(time frame: within one month after enrollment)_
