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 Results may not be published yet.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.
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

Summary

This study looked at 24 people with Complex Regional Pain Syndrome (CRPS) type I in their legs who already use a device that stimulates nerves near the spine (dorsal root ganglion stimulation) to control pain. Researchers used special wearable sensors to track things like heart rate, breathing, sleep, and activity while the device was on and off. The goal was to see if the device affects more than just pain, helping doctors better understand and manage the condition.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

24 people

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

Inclusion Criteria: * Patients diagnosed with Complex Regional Pain Syndrome Type I (CRPS I) of the lower limbs. * Currently treated with Dorsal Root Ganglion Stimulation (DRGS). * Patients must experience \> 50% pain relief with DRGS therapy for at least three months. * Willingness and ability to comply with the study requirements, including wearing biosensors, and sharing their physiological parameters. Exclusion Criteria: * Refusal or inability to wear biosensor wearables. * Current pregnancy. * Patients with other significant medical conditions that could affect autonomic function. * Known allergies or intolerance to materials used in biosensors. * Diagnosis of untreated Obstructive Sleep Apnea Syndrome (OSAS). * Ongoing psychiatric disorders
