About this study
Official title: A Grounded Theory of Phrenic Nerve Reconstruction for the Treatment of Diaphragmatic Paralysis - A Biopsychosocial Approach to Surgical Evaluation and Outcomes.
This study utilizes a grounded theory methodology to explore patient experiences of phrenic nerve reconstructive surgery as a treatment for diaphragmatic paralysis.
- Conditions
- Diaphragmatic Paralysis, Pain, Chest, Breath Shortness
- Keywords
- Grounded Theory, Diaphragmatic Paralysis, Diaphragm, Respiratory System, Pain
- Medical subject headings
- Respiratory Paralysis, Chest Pain, Dyspnea, Pain
What is being measured
The primary outcome is the main question the study is designed to answer.
Semi-Structured Interviews.
The interviews will serve a dual purpose: first, to delve into the daily experiences of individuals living with diaphragmatic paralysis, aiming to uncover the practical and emotional realities they face; and second, to explore the experiences and perceived outcomes of phrenic nerve surgery as a treatment for diaphragmatic paralysis.
Measured: Participants are interviewed one week before and 12 months after the surgery.

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 2 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 6 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Jeannine Sico, RN. (732-741-0970 ext. 1175, jsico@arsahealth.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
