About this study
Latissimus Dorsi (LD); Medial sacrum, lumbar vertebrae and lower thoracic vertebrae 10-12 lateral to the spinous processus. It is a fan-like wide muscle that connects to the inferior angle of the scapula and ribs, adheres to the anterior surface of the proximal humerus and continues with aponeurosis of the contralateral Gluteus Maximus below. The activation of the LD muscle during the functional reach activity, which we use most frequently in daily living activities, affects the upper extremity and trunk movements. Therefore it is important muscle that affects the quality of movement.
The study include individuals with stroke that diagnosed by the neurologist and include healthy subjects. During sitting activity, they will be required to reach three different distances in the sagittal and scapular plane: arm length, 125% of the arm length and end point where it can reach the modified functional reach test. During the activity, electromyography (EMG) activation of latissimus dorsi, anterior deltoid and erector spina muscles will be examined with electromyographic device.

Hypothesis originating from the investigation:
H1: Latissimus dorsi muscle segments show different activation during functional reach activity.
H2: Activation of latissimus dorsi muscle segments is affected by reaching direction during functional reach activity.
H3: Activation of latissimus dorsi muscle segments is affected by reaching distance during functional reach activity.
Read the detailed description
Measurements will be made during the sitting activity of the individuals included in the study. Individuals will be asked to reach midsternal height cups in two separate planes, sagittal and scapular, at arm's end, 125% of arm's distance and end point where it can reach according to modified functional reach test.
Muscle activation of latissimus dorsi, erector spina and anterior deltoid muscles will be measured by superficial electromyographic measurement. Muscle activation according to SENIAM for erector spina and anterior deltoid will be evaluated. For latissimus dorsi, activation will be measured in six segments separated according to anatomic dissection.
Reach activity will be performed 3 times on each side and at 1 minute intervals.

Questions about this trial
What is this clinical trial studying?
An observational study of Stroke, run by Hacettepe University at 1 site in Turkey (Türkiye).
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 6 inclusion and 6 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 20 Apr 2022. 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 Turkey (Türkiye). 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?
Surface electromyographic measurement (time frame: 90 minutes). 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 NCT04181151, which also lists 6 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 20 Apr 2022; AzTrials last refreshed its copy on 8 Nov 2026.
