What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study evaluates the efficacy of adding manual Diaphragmatic Release Technique (DRT) versus Targeted Inspiratory Muscle Training (IMT) to standard medical therapy in patients with stable pulmonary fibrosis. Forty participants are randomly allocated into two equal groups: Group A: Receives manual therapy (cranial and lateral traction to the rib cage for 10-15 minutes) 3 times per week for 12 weeks alongside standard medical care. Group B: Performs targeted inspiratory muscle training using a threshold device (5-7 sets of 6-10 breaths at 30-40% perceived effort) 3 times per week for 12 weeks alongside standard medical care.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Confirmed clinical diagnosis of stable pulmonary fibrosis (diagnosed via HRCT scan and medical evaluation). Age 18 years or older (both males and females). Clinically stable condition with no acute pulmonary exacerbations or respiratory tract infections within the last 4 weeks. Mild-to-moderate pulmonary restrictive impairment baseline. Ability to follow verbal instructions and perform spirometry testing, 6-minute walk test, and threshold inspiratory muscle training maneuvers. Exclusion Criteria: * Acute respiratory exacerbation or hospitalization within the past 4 weeks. Severe cardiac comorbidities (e.g., unstable angina, recent myocardial infarction, congestive heart failure, or uncontrolled severe hypertension). Severe orthopedic, neuromuscular, or musculoskeletal conditions that prevent participation in exercise training, manual therapy, or 6MWT testing. Recent chest or abdominal surgery (within the past 3 months). Cognitive impairment or psychiatric disorders that impede understanding of instructions or adherence to intervention protocols. Participation in another formal pulmonary rehabilitation program or clinical trial concurrently or within the past 30 days
