About this study

Official title: The Effect of Smoking on Pain Threshold, Cervical Position Sense, and Grip Strength in Women

This study aims to investigate the effects of smoking on pain threshold, cervical position sense, and grip strength in women. Measurements will include pressure pain threshold (PPT), cervical position sense (CPS), grip strength, and pinch strength.

Read the detailed description

Smoking is widely recognized as one of the leading preventable causes of mortality and morbidity worldwide and constitutes a major public health problem. Smoking is thought to negatively influence pain perception, proprioceptive sensory feedback, and muscle performance. In this context, examining the combined effects of smoking on pain threshold, CPS, and grip strength in women may contribute to a more comprehensive understanding of the multidimensional impact of smoking on the neuromuscular and sensory systems. Therefore, the aim of this study is to investigate the effects of smoking on pain threshold, CPS, and grip strength in women.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Grip strenght

    Participants will be instructed to grasp the device tip between the thumb and the lateral aspect of the index finger's middle phalanx and to apply maximal force for 3 seconds, followed by relaxation.

    Measured: The measurements will be lasted 5-10 minutes.

  2. Pain pressure threshold

    Measurements will obtained from anatomical landmarks that have been frequently used in previous studies and reported to be reliable and sensitive.

    Measured: The measurements will last 5-10 minutes.

  3. Cervical Position Sense

    Using the CROM device, deviations from neutral head position were recorded in all three anatomical planes. With eyes closed, participants were then asked to perceive a target position passively guided by the examiner.

    Measured: The measurements will take 5-10 minutes.

Questions about this trial

What is this clinical trial studying?

An observational study of Smoking ( Cigarette) and Women, run by Karabuk 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 1 inclusion and 5 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 12 Jun 2026. 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?

Grip strenght (time frame: The measurements will be lasted 5-10 minutes.). The study lists 3 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 NCT07611760, which also lists 1 linked publication.

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 12 Jun 2026.
