Age-related Changes of Shoulder Muscles
An observational study of Electromyography, run by University of Alcala.
Trial summary
A cross-sectional descriptive study, in which the surface electromyographic activity of five shoulder muscles was compared in three populations: older adults, middle-aged adults and young adults.

About this study
Official title: Age-related Changes in Activation Patterns of Shoulder Muscles
A cross-sectional descriptive study, in which the surface electromyographic activity of five shoulder muscles was compared in three populations: older adults, middle-aged adults and young adults. The evaluation of the electromyographic data offers a suitable foundation to understand aging process.
This supports that surface electromyography provide information about the aged shoulder muscles. Loss of functionality is suffered by a high percentage of older adults, which greatly limits their physical activity. In this sense, this paper presents findings that might be related with possible therapeutic approaches in subsequent studies.
Read the detailed description
The purpose of the present work was to assess neuromotor abnormalities in aging shoulder. Twenty young adults (20-42), 20 middle-aged adults (43-67) and 20older adults (>68) were recruited. A comparative electromyography (EMG) study was performed on the upper and lower trapezius, middle deltoid, infraspinatus and serratus anterior. The EMG measurement (root mean square (RMS)) and onset time of isometric contractions were analyzed. Body mass index and strength were also tested.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Group I: Older adults | healthy subjects older than 68 years old whose shoulder muscle are measured by surface electromyography | |
| Group II: Adults | healthy subjects 43 to 67 years old, whose shoulder muscle are measured by surface electromyography | |
| Group III: Young adults | healthy subjects 20 to 42 years old, whose shoulder muscle are measured by surface electromyography |
What is being measured
The primary outcome is the main question the study is designed to answer.
The mean Root Mean Square (RMS) value
The electromyographic data were captured simultaneously on a PC by using the LabChart® software. Within the time interval from 2 to 4 seconds after contraction initiation a power spectrum analysis was performed together with the determination of RMS values. The mean RMS values were automatically obtained from the software
Measured: 30 minutes
onset latency
Start of contraction on the basis of 15% of RMS
Measured: 30 minutes
Secondary outcomes (2)

The record says: finished, as of the sponsor's last update on 28 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.
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?
The mean Root Mean Square (RMS) value (time frame: 30 minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02974452, which also lists 3 linked publications.
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 28 Nov 2016.
