About this study
Official title: Electromyographic Activity of Masticatory Muscles in Post-pubertal Females With Forward Head Posture and Temporomandibular Disorders: An Observational Trial
The aim of this study was to evaluate masticatory muscle electrical activity in post-pubertal females with forward head posture (FHP) and temporomandibular disorders (TMD) as well as in post-pubertal females with neutral head posture and with no temporomandibular disorders.
Read the detailed description
It has been demonstrated by a previous study that a strong relationship exists between forward head posture and temporomandibular disorders and that individuals with forward head posture and temporomandibular disorders exhibit alterations in masticatory muscle electromyographic activity either as a result of the disorder itself or due to a compensatory mechanism associated with the symptoms of temporomandibular disorders . As a consequence, the aim of the study was to evaluate the electromyographic activity of the masticatory muscles in post-pubertal females with forward head posture and temporomandibular disorders as well as in post-pubertal females with neutral head posture and with no temporomandibular disorders.

Questions about this trial
What is this clinical trial studying?
An observational study of Head Pain and TMJ Disorder, run by Cairo University at 1 site in Egypt.
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 5 inclusion and 2 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 8 Feb 2023. 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 Egypt. 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?
Electromyographic (EMG) activity of masticatory muscles (time frame: 8 months). 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 8 Feb 2023; AzTrials last refreshed its copy on 7 Nov 2026.
