How different electrical frequencies affect muscle strength and pain
Part of Bones, joints & muscles, Pain clinical trials.
This study tests whether changing the electrical frequency during a type of nerve stimulation (percutaneous neuromodulation) can improve muscle strength and reduce pain sensitivity in people with a hidden muscle knot (trigger point) in the shoulder blade area.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must have at least one hidden muscle knot (called a latent trigger point) in the infraspinatus muscle (shoulder blade area).
- You need to be able to read and understand a consent form and agree to participate.
- You cannot be taking any medicines that affect how your muscles work.
- You cannot have had surgery on your shoulder or spine.
- You cannot have conditions like whiplash, dislocations, or fractures, or any nerve problems (such as a pinched nerve).
- You cannot have fibromyalgia or other widespread muscle/joint conditions.

This study tests two different needle-based treatments (dry needling and percutaneous electrolysis) to see which one works better for relieving long-term shoulder pain caused by tight muscle knots (trigger points). If you join, you'll receive one of these treatments, which may help reduce your pain and improve shoulder function.
This study tests whether using electrical stimulation to guide a numbing catheter placed near the shoulder reduces pain after shoulder replacement surgery. It may help patients feel more comfortable and use less pain medicine after their operation.
This study compares two non-invasive nerve stimulation methods to see which one better reduces pain and improves function in people with cervical radiculopathy (nerve pain in the neck and arm).
This study compares two non-invasive treatments—low-level laser therapy and electrical nerve stimulation—to see which works better for relieving moderate to severe shoulder pain in people who have had a stroke. If you have had a stroke in the last 2 weeks to 6 months and have shoulder pain, this trial may be an option for you.
This trial tests whether stimulating the nerve roots in the shoulder area can reduce long-lasting nerve pain in one arm. It may help people whose arm pain has not improved with standard nerve-pain treatments.
This study tests whether heating (radiofrequency) applied to shoulder nerves, with a fluid injection to free up tissue, helps improve pain and movement in people with frozen shoulder (adhesive capsulitis). It compares treating three nerves versus just one nerve to see which works better.
