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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 looks at whether applying targeted heat (thermal radiofrequency) to a specific nerve in the arm can safely reduce severe elbow stiffness in adults who developed spasticity after a brain or spinal cord injury. Researchers will measure changes in elbow movement, muscle tightness, and quality of life in 64 participants. The goal is to see if this nerve treatment offers lasting relief when standard therapies have failed.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
thermal radiofrequency applied to the musculocutaneous nerve
What this could lead to
If successful, this could offer a new, minimally invasive option to reduce severe elbow spasticity and improve quality of life for people with brain or spinal cord injuries.
What could go wrong
This is an observational study with no control group, so results may be less definitive. The procedure carries risks like nerve damage or incomplete relief, and long-term effects are not yet known.

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.

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

Inclusion Criteria: * Signed informed consent. * Age 18 years or older. * Diagnosis of spasticity secondary to central nervous system injury. * Predominant elbow flexor spastic pattern dependent on the musculocutaneous nerve. * Patients with severe spasticity refractory to conservative treatments who underwent thermal radiofrequency treatment of the musculocutaneous nerve during the study period. Exclusion Criteria: * No signed informed consent. * Age under 18 years. * Radiofrequency treatment applied to patients without central nervous system injury. * Absence of follow-up after radiofrequency treatment, for any reason, for a minimum period of 2 months.
