Individualiseret Cryoneurolyse til Behandling af Smerter i Forbindelse med Spasticitet i Øvre og Nedre Ekstremiteter (ICE)

2. november 2026 opdateret af: Oxford University Hospitals NHS Trust

Individualiseret Cryoneurolyse til Behandling af Smerter i Forbindelse med Spasticitet i Over- og Underekstremiteterne (ICE): et Pilot Randomiseret Kontrolleret Studie

Spasticity is an umbrella term for impairments of muscle tone and control in people with damage to the brain and spinal cord. It is highly prevalent and results in pain, stiffness, and contribute to difficulties in activities of daily living. Current treatment options are limited, and many people experience only partial reduction in spasticity and frequent repeated treatments are needed.

Cryoneurolysis is a medical technique which involves the controlled freezing of the nerves. It has been approved in the UK for the treatment of pain in the context of spasticity through the targeting of nerves which control problematic muscles. Oxford University Hospitals NHS Foundation Trust has been offering this treatment routinely since January 2024. This pilot study aims to improve the understanding of the potential effectiveness of this treatment and its potential side effects when compared with a more commonly used treatment (Botulinum Toxin).

Participants will be randomly allocated to receive usual care with Botulinum Toxin (control group) or usual care with Cryoneurolysis (intervention group). The investigators will assess pain, goal attainment, side effects, spasticity, disability and independence in daily activities, and movement of the arm and leg. Assessments will be at baseline and then 6-, 12-, 18-, and 24-weeks following treatment. Participants who are randomised to the control group will have the opportunity to receive cryoneurolysis treatment after the 12 week follow up assessment.

The results of this study will help to guide future studies to examine the effectiveness of this treatment.

Detaljeret beskrivelse

Spasticity is an umbrella term for impairments of muscle activity and control in the context of damage or dysfunction in the central nervous system, occurring in up to 87% of spinal cord injury patients, 42% of stroke patients, and 80% of patients with multiple sclerosis. Spasticity results in pain, stiffness, and restrictions to activity including difficulties in personal care and mobility and a significant impact on quality of life.

Treatments including oral medications, botulinum toxin injections, and physical therapies can provide some degree of relief, but effectiveness varies widely. Many patients experience only partial reduction in spasticity, contributing to ongoing functional limitations. Botulinum toxin injections provide temporary relief necessitating frequent treatments (every 3-4 months). This is burdensome for patients and healthcare providers, with associated time and treatment costs. Pharmacological treatments can lead to systemic side effects including drowsiness, dizziness, and cognitive impairments. Surgical interventions are resource-intensive and require specialised medical facilities. Their associated costs, in terms of financial resources and healthcare infrastructure, significantly limit access for certain patients.

Cryoneurolysis, a novel medical technique, involves the controlled freezing of nerve tissue to temporarily disrupt its function. While primarily used for pain, there is a growing interest in its application for managing spasticity and it is currently approved for the treatment of pain in the context of spasticity at Oxford University Hospitals NHS Trust. Observational studies suggest immediate relaxation of the affected muscles, resulting in improved joint range of motion, enhanced functional mobility, and reduced pain. The investigators' own open-label proof-of-principle clinical data suggest the potential for substantial improvements in the impact of spasticity on quality of life.

This pilot randomised controlled study aims to improve the understanding of the potential clinical effectiveness and side effect profile of cryoneurolysis as a treatment for pain in the context of spasticity in people with a range of neurological conditions (e.g. acquired brain injury (ABI), spinal cord injury, stroke, multiple sclerosis).

Eksperimentel: Cryoneurolyse (+ sædvanlig pleje)
Procedure: Cryoneurolysis

Nerves that require treatment, and the number of treatments required for each nerve will be identified by routine clinical judgement. Nerve targets are identified using an ultrasound machine. The handheld Iovera cryoneurolysis device will be used for treatment.

Participants will receive up to 4 treatments of cryoneurolysis for each nerve or nerve branch that requires treatment. It is anticipated that participants will have between 1 and 5 nerves or nerve branches per limb treated. Each Cryoneurolysis treatment takes 110 seconds. Total treatment time will be determined by number of nerves targeted and number of cryoneurolysis treatments per nerve. The shortest duration, with setup, is likely to be 60 minutes and the longest 120 minutes.
