This study tests two ways to manage pain after hip replacement surgery. One group gets a nerve block plus a second nerve block; the other gets a nerve block plus wound numbing. The goal is to see which method reduces pain and the need for opioid painkillers. About 102 adults havi…

This study tests whether a program of exercise and ergonomics training can reduce muscle and joint pain in teachers. About 80 teachers who have had pain for at least three months will be randomly assigned to receive the training or not. Researchers will measure changes in pain, d…

This study tests a web-based app called IAMABLE that provides evidence-based rehabilitation strategies for people with chronic conditions like heart disease, arthritis, or neurological disorders. Fifty adults aged 45 to 75 will use the app for 4 months to set goals and learn abou…

This study tests whether eating freeze-dried wild blueberry powder every day for 12 weeks can improve gut health, reduce inflammation, and ease joint pain in adults with arthritis. Fifty participants will take either the blueberry powder or a placebo, with a 2-week break between …

This study tests whether extra support for case managers helps veterans leaving the military better manage pain and reduce risky substance use. About 1800 veterans will take part. The program focuses on non-drug pain treatments and counseling.

This study aims to learn more about rare skeletal disorders by collecting medical records, blood samples, and genetic data from 100 participants. People with known or suspected bone conditions, as well as their healthy family members, can join either remotely or in person. The go…

This study looks at whether sulfasalazine, a drug for inflammatory arthritis, makes the standard diabetes blood test (HbA1c) falsely low. That could mean diabetes goes undiagnosed or is undertreated in these patients. Researchers will use continuous glucose monitors and fasting b…

This study translates and tests several health questionnaires—covering pain, arm and leg function, mood, and daily activities—for use with Albanian-speaking people. Researchers will check if the translated versions are reliable and accurate by giving them to about 300 participant…

This study is creating a collection of blood, urine, and leftover surgical tissue from 350 patients with bone, calcium, and growth plate disorders. The goal is to better understand how these diseases progress and to find markers that could predict outcomes. No new treatments are …

This study tests a new tool called the PRISM Dashboard, which gives physiotherapists feedback on how their decisions compare to their peers. The goal is to see if this feedback helps reduce differences in care for people with muscle and joint pain. About 60 physiotherapists and t…

This study is creating a large collection of joint fluid and blood samples from 500 people with different types of arthritis. Researchers will use these samples to test new biomarkers that could help diagnose arthritis earlier and monitor how the disease changes over time or with…

This pilot study is measuring prednisolone levels in 120 people with inflammatory diseases like thyroid eye disease, vasculitis, COPD, asthma, and others. Participants take high-dose prednisolone as part of their routine care, and researchers take timed blood samples to see how t…

This study follows 252 adults with muscle, bone, or joint problems (like arthritis, back pain, or after surgery) to see how well they do their prescribed home exercises. Researchers will track who sticks with the program and why, looking at factors like pain, mood, and support. T…

This study tests whether using a virtual reality (VR) headset during shoulder exercises helps patients feel more engaged and motivated. Fifty adults with shoulder problems will do rehab exercises in a VR environment and then answer questionnaires about how easy and immersive the …

This study looks at 320 adults who are about to start strong immune-suppressing therapy and have already had at least two COVID-19 shots. Researchers want to find out if giving a COVID-19 booster right before starting therapy or waiting six months provides better protection. Part…

This study aims to create a secure national database for muscle and joint (musculoskeletal) conditions by collecting routine data from community clinics and GP practices. About 22,000 adults will have their information anonymously gathered to help develop a dashboard that tracks …

This study watches 2000 people having hip or knee replacement surgery to see how long spinal anaesthesia lasts. The goal is to learn how the amount of anaesthetic affects timing, helping doctors decide if patients can safely go home the same day. No new treatments are tested—just…

This study looks at how often people can return to sports at least three years after total knee replacement. It compares three different types of knee prostheses to see if one type leads to better sports participation. The study will include 660 adults who had their first knee re…

This study looks at how changing the heel cushion on an ankle-foot brace (AFO) affects walking in people who use one daily. Forty adults with leg injuries or nerve problems will try four different heel wedges—tall or short, soft or firm—while walking at controlled speeds. Researc…

This study looks at how 3D computer simulation and printing can help surgeons better plan and perform bone correction surgeries. Researchers will compare the planned corrections to the actual results in 100 children and young adults with rare bone deformities. The goal is to make…

This study follows 4,000 children who receive orthopedic implants (like rods or screws) during standard care for bone fractures, deformities, or hip problems. Researchers will track how long the implants last, any complications, and how well they work over time. The goal is to ga…
