What is the purpose of this trial?

This trial explores how dry needling, a technique using thin needles to relax tight muscles, affects the nervous system in individuals with muscle spasms after a stroke. The goal is to determine if this treatment can ease muscle stiffness and improve movement. The study lasts only two days. Individuals who have experienced muscle stiffness on one side of their body due to a stroke for over a year and have medical clearance may be suitable candidates for this trial. As an unphased trial, it offers participants the chance to contribute to pioneering research that could lead to new treatment options for stroke survivors.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What prior data suggests that dry needling is safe for treating muscle spasms after stroke?

Research shows that dry needling might help with muscle problems, such as those following a stroke. Some studies suggest it can reduce muscle stiffness and improve movement. However, the safety of dry needling for stroke patients remains unclear. Reviews indicate insufficient strong evidence to confirm its safety. While dry needling doesn't appear to cause major issues, the lack of solid data leaves some uncertainty. Consulting a healthcare provider is advisable for any concerns. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike the standard treatments for muscle spasms after a stroke, which often involve medications or physical therapy, dry needling is a hands-on technique that directly targets the muscle's trigger points. Researchers are excited about dry needling because it may offer faster relief from spasticity by altering how the nervous system communicates with the muscles, potentially improving movement more quickly than traditional methods. Additionally, dry needling is less invasive than surgical options and avoids the systemic side effects associated with medication.

What evidence suggests that dry needling is effective for muscle spasms after stroke?

Research has shown that dry needling can reduce muscle tightness in people who have had a stroke. One study found it lessened hand stiffness, a common post-stroke issue. Another study reported that a single session of dry needling in the legs reduced both muscle tightness and pain sensitivity. Additionally, dry needling has eased finger muscle tightness and improved movement in stroke patients. In this trial, one group of participants with spasticity from stroke will receive dry needling to relieve spasticity in the target muscle. Another group, consisting of individuals with no known neurological injury, will also receive dry needling to examine its effects on the nervous system. These studies suggest that dry needling might help manage muscle tightness and improve movement for those recovering from a stroke. ^{3 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for adults over 18 years old with muscle stiffness from a stroke that happened more than a year ago and are medically stable. It's also for those without neurological injuries. People can't join if they have certain medical conditions like uncontrolled diabetes, bleeding issues, severe anxiety, metal allergies, or heart problems.

Inclusion Criteria

I am over 18 and do not have any known brain injuries or conditions.

I had a stroke over a year ago, have stable health, and experience stiffness in my ankle or wrist.

Exclusion Criteria

My diabetes is not under control.

My motor nerves are damaged and don't respond well to treatment.

I have a severe fear of needles.

What Are the Treatments Tested in This Trial?

Interventions

• Dry Needling

Trial Overview

The study tests dry needling—a technique where a thin needle is used to relieve muscle knots and pain in people with spasticity after stroke. Participants will undergo this procedure once and then be evaluated on reflexes and limb function over two days.

How Is the Trial Designed?

Group I: Individuals with spasticity resulting from stroke Experimental Treatment 1 Intervention

This is an experimental intervention in which individuals will receive dry needling to relieve spasticity in the target muscle. The study team will examine the effects of this treatment on the nervous system by performing assessments just prior to, immediately after, 90 minutes after, and 72 hours after dry needling. These assessments will examine how you move your arm or leg and how your nervous system responds to non-invasive nerve stimulation.

Group II: Individuals with no known neurological injury Experimental Treatment 1 Intervention

This is an experimental intervention in which individuals will receive dry needling of an arm or leg muscle. The study team will examine the effects of this treatment on the nervous system by performing assessments just prior to, immediately after, 90 minutes after, and 72 hours after dry needling. These assessments will examine how you move your arm or leg and how your nervous system responds to non-invasive nerve stimulation.

Published Research Related to This Trial

In a study involving nine rabbits, dry needling of myofascial trigger points significantly reduced spontaneous electrical activity (SEA) in the treated muscle, indicating its effectiveness in relieving myofascial pain.

The results suggest that eliciting local twitch responses during dry needling is crucial for reducing SEA, highlighting that this response, rather than just the needling itself, plays a key role in the treatment's efficacy.

A case study of a 62-year-old male with chronic shoulder spasticity post-stroke showed significant improvement in spasticity and shoulder range of motion after 9 sessions of dry needling targeting specific muscle trigger points.

The results suggest that dry needling can be an effective treatment for alleviating chronic post-stroke shoulder spasticity, providing a non-drug intervention option for patients with similar conditions.

Dry needling is generally safe and well tolerated for treating myofascial pain, but there is a risk of severe complications, such as an acute spinal epidural hematoma, as highlighted in this case report.

Healthcare providers should exercise caution when performing dry needling near the spine, and any sudden neuropathic pain following the procedure should be evaluated immediately with advanced imaging to ensure spinal cord integrity.

Dry needling (DN) significantly reduced wrist flexor spasticity in stroke patients, as evidenced by a decrease in Modified Modified Ashworth Scale (MMAS) scores from a median of 2 at baseline to 1 immediately after treatment and one hour later.

The study, involving 29 stroke patients, also showed improvements in other measures of muscle function and excitability, indicating that DN may effectively lower muscle stiffness and enhance movement shortly after treatment.

In a study involving 39 physiotherapists and 7629 treatments, trigger point dry needling (TrP-DN) was found to have a high incidence of mild adverse events (AEs), with 1463 reported cases, but no significant AEs occurred, indicating a very low risk of serious complications (≤ 0.04%).

Common mild AEs included bruising (7.55%) and bleeding (4.65%), but the overall safety profile suggests that TrP-DN is a safe treatment option for myofascial pain when performed by trained physiotherapists.
