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
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 This study
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 Results may not be published yet.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.

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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at 26 people with peripheral arterial disease (PAD) to see how arm exercise changes oxygen levels in their leg muscles. Participants used an arm ergometer while a sensor measured calf oxygen saturation. The goal was to understand why arm training can improve leg function without causing leg pain during exercise.

Show the full entry requirements

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

Inclusion Criteria: 1. aged ≥ 50 years; 2. with PAD confirmed by clinical diagnosis and ankle-brachial index (ABI) \< 0.90 in one or both limbs; 3. experiencing symptoms of intermittent claudication (IC) during walking; 4. with a body mass index (BMI) not exceeding 30 kg/m²; 5. with medical clearance to participate in the project; 6. presenting calf skinfold thickness less than 20 mm due to interference of adiposity with the light penetration of the NIRS probe and finger oxygen saturation \> 95% to ensure that impaired pulmonary gas exchange does not affect the calf oxygen saturation measurements.
