Brief 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. 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.

Conditions

Electromyography

Outcome Measures

Primary Outcomes (2)

• 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

  30 minutes

• onset latency

  Start of contraction on the basis of 15% of RMS

  30 minutes

Secondary Outcomes (2)

• maximal isometric voluntary contraction

  5 minutes

• body mass index

  5 minutes

Study Arms (3)

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

Eligibility Criteria

• Age: 20 Years - 90 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

Study Population

Participants came from Madrid and Castilla La Mancha (Spain) and voluntarily attended the Unit of the Research Group "Physical Therapy in Women´s Health Processes" in the Department of Physical Therapy, University of Alcalá, and the Ocaña Senior Center.

You may qualify if:
