The Impact of Perineural Injection Therapy for Adhesive Capsulitis.

Официальное название

The Impact of Perineural Injection Therapy for Adhesive Capsulitis at a Single Centre University Hospital in Selangor: A Pilot Study

Обзор

The goal of this clinical trial is to learn if Perineural Injection Therapy (PIT) works to treat adhesive capsulitis (frozen shoulder) in adults. It will also learn about the safety of PIT. The main questions it aims to answer are: Does PIT reduce shoulder pain and improve shoulder range of motion more effectively than conventional therapy alone? What side effects or medical problems do participants experience when receiving PIT? Researchers will compare PIT to conventional therapy to see if PIT works better to treat adhesive capsulitis. Participants will: Receive either: PIT once weekly for 6 weeks plus physiotherapy and oral analgesics (excluding NSAIDs), or Conventional therapy only (physiotherapy and analgesics including NSAIDs) Attend scheduled follow-up visits at Week 6, 1 month, and 3 months after treatment Perform daily home-based shoulder exercises and record their analgesic use and any side effects in a patient diary

Study Title:

The Impacts of Perineural Injection Therapy on Adhesive Capsulitis in a Single Centre Hospital in Selangor: A Randomized Controlled Trial Pilot Study

Study Overview :

Adhesive capsulitis, commonly known as "frozen shoulder," is a painful condition that limits shoulder movement and affects daily activities such as dressing, reaching overhead, or lifting objects. It often affects adults between the ages of 40 to 60 and can last for months or even years. For some, the condition may improve with physiotherapy and medication, but others continue to struggle with pain and stiffness.

This clinical trial aims to explore a new method of treatment called Perineural Injection Therapy (PIT). PIT involves injecting a natural sugar solution (5% dextrose) just under the skin at specific nerve areas around the shoulder. This method targets nerves that may be irritated or inflamed and helps to reduce pain and improve movement.

Although PIT has shown promising results in treating other painful conditions like nerve entrapments and joint pain, its effects on frozen shoulder have not yet been well studied. This research hopes to find out if PIT can help relieve pain, improve shoulder movement, and enhance function in people with frozen shoulder.

The current treatment options for frozen shoulder (such as physiotherapy, painkillers, and steroid injections) do not work for everyone. PIT is a non-surgical option that may help the healing process by calming nerve-related inflammation. This study will evaluate how effective PIT is and whether it is safe for use in treating adhesive capsulitis.

Participants will be randomly assigned to one of two groups:

Intervention Group: Will receive six weekly sessions of PIT combined with physiotherapy and oral pain medication (excluding NSAIDs like ibuprofen).

Control Group: Will receive only conventional therapy, including physiotherapy and standard painkillers (including NSAIDs).

All participants will:

Be evaluated for shoulder pain, range of motion, and ability to perform daily activities at the beginning of the study, at Week 6, 1-month, and 3-months after treatment.

Be taught home exercises to do daily to improve shoulder mobility and strength.

Be asked to keep a diary to record medication use and any side effects they experience.

Receive support and regular follow-ups from the research team to monitor progress and manage any issues.

Adults aged 18 and above who have been diagnosed with primary (idiopathic) adhesive capsulitis for at least 3 months and are experiencing significant shoulder pain and stiffness may be eligible. Participants must be able to understand and follow instructions in Malay or English.

People will not be eligible if they:

Have had a shoulder injection or surgery recently

Have other serious shoulder problems (like a fracture or nerve injury)

Have poorly controlled diabetes or are on certain medications that may interfere with the study

PIT is generally safe and has been used in other conditions with minimal side effects, such as mild pain or redness at the injection site. In this study, participants will be closely monitored for any adverse effects.

Potential benefits include reduced pain, improved shoulder movement, and better overall function. The information gathered may help develop better treatment options for others with frozen shoulder in the future.

Each participant will be involved in the study for approximately 3 to 4 months, including the 6-week treatment period and two follow-up assessments.

Вмешательства

• Другое perineural injection
  Intervention The procedure will be performed by a rehabilitation physician who has obtained hospital-level credentialing and privileging to practice Perineural Injection Therapy (PIT). The physician has undergone hands-on training with Dr. Lyftogt-certified trainers in Malaysia. PIT will be administered weekly for six week (Total 6 sessions). In addition to this intervention, patient will also receive conventional therapy which is monthly outpatient physiotherapy with supplementary home-based e
• Другое Physiotherapy
  Patients will be receiving a structured home-based exercise program and will be instructed on how to perform these exercises at home. The exercise regime will be 30 minutes, 3 times a day to enhance shoulder mobility and strength in addition to the regular monthly outpatient physiotherapy session. Oral analgesics exclude NSAIDs will be prescribed as needed to manage pain.
