Chronic Shoulder Pain

This study aims to compare the effects of pulsed radiofrequency (PRF) treatment of the suprascapular nerve using suprascapular notch and midpoint approaches on pain, shoulder function, and muscle strength in patients with chronic shoulder pain due to rotator cuff tendinopathy. Patients will be randomly assigned to one of the two intervention groups. Clinical evaluations will include pain assessment using the Numeric Rating Scale (NRS), functional assessment using the Shoulder Pain and Disability Index (SPADI), and quality of life assessment using the Short Form-36 (SF-36). In addition, shoulder range of motion will be measured goniometrically, muscle thickness of the supraspinatus and infraspinatus will be evaluated by ultrasonography, and shoulder muscle strength will be assessed using an isokinetic dynamometer. Assessments will be performed at baseline, 24 hours, 1 month, and 3 months after the intervention. The results of this study are expected to provide evidence regarding the optimal approach for PRF treatment of the suprascapular nerve in patients with chronic shoulder pain.

This prospective observational cohort study aims to investigate whether baseline central sensitization and psychological factors predict functional outcomes following rehabilitation in individuals with chronic shoulder pain. Participants with chronic shoulder pain will receive a standardized 6-week physiotherapy and rehabilitation program routinely applied in the clinic. Assessments will be performed before and after treatment, including pain severity, shoulder function, central sensitization symptoms, and psychological factors such as pain catastrophizing. The findings of this study may contribute to a better understanding of biopsychosocial factors affecting rehabilitation outcomes in chronic shoulder pain and help improve individualized rehabilitation approaches.

The purpose of this prospective, observational study is to evaluate the clinical and functional outcomes of ultrasound-guided Pericapsular Nerve Group (PENG) block in patients suffering from chronic shoulder pain. Chronic shoulder pain is a highly prevalent musculoskeletal problem that significantly restricts daily activities and diminishes the patient's quality of life. While conservative treatments and various interventional injections are widely used, long-term efficacy can be limited, and systemic side effects may occur. The shoulder PENG block is a novel regional analgesia technique that specifically targets the articular (sensory) branches of the nerves innervating the shoulder joint capsule without affecting the motor branches. In this single-center study, a total of 45 eligible adult patients with chronic shoulder pain who did not respond to conservative medical treatments will receive an ultrasound-guided PENG block as part of their routine clinical care. The procedure will be performed under sterile conditions using a combination of local anesthetic (lidocaine) and dexamethasone. Patient pain levels will be assessed using the Numerical Rating Scale (NRS), shoulder disability and functional status will be measured using the Shoulder Pain and Disability Index (SPADI), and overall patient satisfaction will be evaluated using the Global Perceived Effect (GPE) score. All parameters will be documented at baseline (before the procedure) and at follow-up visits on the 1st week, 4th week (1 month), and 3rd month post-procedure. The investigators aim to determine the efficacy, duration of effect, and safety profile of this intervention.

Prior research has explored factors influencing muscle activation, including muscle thickness, fear avoidance beliefs (kinesiophobia), and somatosensory integration. In individuals with chronic shoulder pain, various characteristics impacting symptoms and treatment outcomes have been identified, such as psychosocial factors, fear avoidance, central sensitization, somatosensory impairments, and brain morphology changes. These shared characteristics affecting both muscle activation and chronic shoulder pain may potentially modulate upper trapezius muscle activation during functional movements in patients with chronic shoulder pain. Notably, there remains a gap in the literature concerning investigations into the upper trapezius muscle's morphology and quality, fear avoidance, central sensitization, somatosensory impairments, and their interplay with upper trapezius muscle activation in chronic shoulder pain patients. To address these gaps, this study aims to: this study aims to: 1) compare different methods of measuring clavicular kinematics using an electromagnetic tracking system; 2) establish the reliability and validity of measuring muscle thickness and fat infiltration through ultrasound and magnetic resonance imaging; 3) compare shoulder kinematics, muscle activation, muscle morphology, and muscle fat infiltration in individuals with chronic shoulder pain with matched healthy controls; 4) explore the correlation between the factors that may influence upper trapezius muscle activation, including basic data of the subjects, muscle morphology, and muscle fat infiltration.

This feasibility study investigates whether high-intensity interval training (HIIT) is feasible and acceptable for individuals with long-term shoulder pain where low-grade inflammation is suspected. Many patients do not recover fully with current local treatments, and systemic factors such as inflammation, and metabolic changes, additionally disturbances in the functioning of the nervous system often seem to play a role. HIIT is a time-efficient form of exercise that has been shown to improve inflammation and metabolic values and positively influence the balance of the nervous system. In this feasibility study, the investigators are enrolling 15 individuals with persistent shoulder pain (diagnosed with rotator cuff-related shoulder pain or frozen shoulder) with \>3 months of symptoms, and 15 individuals without shoulder complaints. All participants will undergo measurements of inflammatory levels, glycosylated hemoglobin (HbA1c), blood pressure, body composition, pain sensitivity tests, and complete questionnaires about autonomic complaints and quality of life. Participants with shoulder pain will also perform one personalized HIIT session on a cycle ergometer. The investigators will assess whether participants accept a systemic intervention for their shoulder pain, if they are cooperative, and how they feel about the session; additionally, any side effects will be recorded. The aim is to determine whether HIIT is practically feasible and safe for this group and whether there are indications that systemic factors such as inflammation and nervous system function are associated with persistent shoulder pain. The outcome will determine whether follow-up research with a larger study is worthwhile.

People with long-term (chronic) shoulder disorders caused by injuries, overuse or conditions (such as arthritis) often need physiotherapy. This usually includes exercise therapy to help reduce pain, rebuild strength and make every day activities easier. However, it can be hard to stick to an exercise programme. People may stop due to pain, fear of making the symptoms worse or simply loosing motivation. Virtual Reality (VR) is a technology that may help people say engaged with their exercise programmes by making exercises more enjoyable and interactive. When using a headset (similar to goggles), people can see and interact with a 3D virtual world. Their movement, especially their hands and arms, are shown as an 'avatar' (a virtual character) in this virtual world. Exercise can feel more like playing a game or engaging with tasks/challenges, rather than performing repetitive movements. This shift might help reduce focus on pain and increase motivation. VR also provides real-time feedback, helping people track their progress and adjust their movements instantly. This might lead to more accurate and consistent exercise performance and better recovery outcomes. Before we can test whether VR exercise programmes are effective for people with chronic shoulder disorders, we firstly need to understand whether it is practical and acceptable for patients to use. This 'feasibility' study will therefore involve 20 patients with chronic shoulder disorders referred for physiotherapy at the Royal National Orthopaedic Hospital (RNOH) in Stanmore, United Kingdom. Participants will take part in three VR exercise sessions at the RNOH over a three-week period. Levels of pain, quality of life and sleep quality etc. will be measured before and after three weeks. Interviews will also be held up to two weeks after the final session to explore people's experiences and thoughts towards the VR exercise programme. The results will help us decide if a larger study should go ahead.

This study relies on the use of a smartphone application (SOMA) that the investigators developed for tracking daily mood, pain, and activity status in acute pain, chronic pain, and healthy controls over four months.The primary goal of the study is to use fluctuations in daily self-reported symptoms to identify computational predictors of acute-chronic pain transition, pain recovery, and/or chronic pain maintenance or flareups. The general study will include anyone with current acute or chronic pain, while a smaller sub-study will use a subset of patients from the chronic pain group who have been diagnosed with chronic low back pain, failed back surgery syndrome, or fibromyalgia. These sub-study participants will first take part in one in-person EEG testing session while completing simple interoception and reinforcement learning tasks and then begin daily use of the SOMA app. Electrophysiologic and behavioral data from the EEG testing session will be used to determine predictors of treatment response in the sub-study.

The goal of this clinical trial is to learn if laterality training (a type of brain-based therapy) can help reduce pain and change how people with chronic musculoskeletal pain experience and describe their pain. The study will focus on adults with shoulder or knee pain lasting longer than 6 months. The main questions it aims to answer are: Does laterality training lead to a reduction in self-reported pain levels? Does laterality training reduce the area of the body that participants indicate as painful in their pain drawings? Does laterality training improve accuracy and speed in left/right judgment tasks? Researchers will compare participants who complete laterality training to those who complete a non-therapeutic cognitive task (a word puzzle) to see if laterality training changes pain drawings and improves pain outcomes. Participants will: Complete a pre-intervention assessment including pain ratings, pain drawings, and a left/right judgment test Be randomly assigned to one of two groups: Intervention group: Complete 5 one-minute sessions of laterality training using a tablet-based app called Recognise™, identifying left or right hand/foot images depending on the location of their pain Control group: Complete a 10-minute crossword puzzle activity (non-therapeutic) Complete the same assessments after the activity (pain ratings, pain drawings, left/right judgment test) The study will take place at two outpatient physical therapy clinics. Participation involves a single session lasting approximately 30-45 minutes. There is no cost to participate, and no compensation is provided. Participation is voluntary, and all personal data will be kept confidential. This research will help determine whether laterality training, a non-invasive brain-based technique, can reduce pain and improve quality of life in people with long-standing musculoskeletal pain.

The objective of this clinical trial is to determine whether cognitive functional therapy is superior to therapeutic exercises for the treatment of chronic shoulder pain. The main questions it aims to answer are: Is cognitive functional therapy superior to therapeutic exercises for pain and disability in individuals with chronic shoulder pain? Is cognitive functional therapy superior to therapeutic exercises for functionality and psychosocial factors? Participants will: Receive 4 to 8 sessions of cognitive functional therapy once a week for four to eight weeks. Follow a therapeutic exercise protocol for eight weeks with a frequency of twice per week.

Shoulder pain is a debilitating musculoskeletal condition with functional, physical, and psychological impacts. Interventions for chronic shoulder pain should address the biopsychosocial model, with Cognitive Functional Therapy emerging as a promising physiotherapy approach. Cognitive Functional Therapy approaches the multidimensional nature of pain, integrating physical and cognitive aspects. The aim of this randomized controlled trial is to compare the effects of Cognitive Functional Therapy with therapeutic exercise on biological aspects of pain (pain intensity, disability, function, perception of improvement/deterioration, and central pain processing), and psychosocial aspects of pain (sleep quality, self-efficacy, and biopsychosocial factors). The hypothesis of this study is that CFT will lead to greater improvements in these outcomes compared to therapeutic exercise.

This pilot randomized controlled clinical trial (RCT) will assess the feasibility and identify the key components necessary for conducting the main RCT, which will involve the comparison of Cognitive Functional Therapy with Therapeutic Exercises in individuals with chronic shoulder pain. The main questions it aims to answer are: * What barriers to the participation of the included individuals might arise? * Will the assessment procedures and outcome measures be feasible and suitable? * What time will be necessary to conduct the assessments? * Will participants be willing to be randomized to the proposed treatment groups? * What barriers to the clinical delivery of Cognitive Functional Therapy in the healthcare system might exist? * Will the treatment(s) be acceptable to patients? * Will participants adhere to the treatment? * What will the recruitment rates be per week/month? * Will there be any selection bias? * Will participant retention be high among the allocation groups? * Will the data be complete? * What will the data variability be? * Will the treatment effects/outcomes be consistent with expectations and previous literature?

Total shoulder surgery (arthroplasty) is a widely successful method of treating shoulder arthritis. Although the goal of the procedure is pain relief, post-operative pain is unavoidable. Pain is a common side effect that many patients undergo while in the clinical setting and is a vital factor in influencing the length of hospital stay, narcotic usage, as well as overall patient satisfaction. Post-operative pain management typically involves elevated usage of narcotics, which is a concern among clinicians and researchers alike. To combat this issue, research is examining intraoperative procedures as a means of reducing post-operative pain scores. Research has discovered the advantages of utilizing local anesthetic techniques as opposed to just general anesthesia. Local anesthetic blocks function by preventing the generation of nerve impulses by increasing the action-potential threshold, thereby inhibiting movement. Previous studies have demonstrated the success of local anesthetic interscalene blocks across several medical procedures. For instance, Exparel (liposomal bupivacaine) has been effective in reducing post-operative pain scores in tonsillectomy and shoulder arthroplasty. Another local anesthetic, Ropivacaine, has been found to be potent when utilized via a cervical paravertebral catheter among thoracic procedures. Our study will compare Exparel (bupivacaine liposome) with Ropivacaine continuous infusion for post-operative pain scores in total shoulder surgery patients. Additionally, we will collect data on complications, length of stay, and other variables.
