Rotator Cuff Related Shoulder Pain

This study aims to analyze the effects of 4 weeks of low-intensity exercise with and without blood flow restriction (BFR) on pain, fear of movement, catastrophizing about pain, strength, and disability in a population with rotator cuff-related shoulder pain. There are two modalities corresponding to the same exercises under different blood flow restriction conditions: 1) 3 low-intensity exercises (30% 1RM) with BFR (50% AOP); 2) 3 low-intensity exercises (30% 1RM) without BFR. Participants will be randomly assigned to one of two groups and will undergo a 4-week intervention. The variables of interest will be assessed in each group for subsequent analysis and comparison.

This study aims to compare the effects of blood flow restricted (BFR) exercise and to examine the differences between various BFR protocols on acute pain reduction in individuals with rotator cuff-related shoulder pain, as well as the exercise tolerance at each intensity and occlusion setting. There are four exercise modalities corresponding to different combinations of intensity (%RM) and percentage of occlusion (%AOP): 1) 30% RM and 30% AOP; 2) 30% RM and 50% AOP; 3) 30% RM and 70% AOP; 4) 30% RM and BFR placebo (cuff without pressure). All participants will complete one session of each of the four exercise modalities, analyzing the variables studied in each for subsequent analysis and comparison.

The aim of this clinical trial is to investigate the effects of an attention shift-based rehabilitation program on clinical outcomes in individuals with rotator cuff-related shoulder pain (RCRSP). The study will evaluate the effects of an attention shift approach, in which motor tasks targeting regions outside the shoulder are performed concurrently with standard shoulder exercises, on pain, functional status, and pain catastrophizing. These results will be compared with those of a standard shoulder rehabilitation program. The main questions this study aims to answer are: Is there a difference in pain levels between individuals with RCRSP who participate in an attention shift-based rehabilitation program and those who participate in a standard exercise program? Is there a difference between these two rehabilitation approaches in terms of shoulder function and pain catastrophizing? Participants will: Be randomly assigned to either an attention shift-based rehabilitation group or a standard shoulder rehabilitation group Participate in supervised exercise sessions twice per week for 6 weeks Attend sessions lasting approximately 60-75 minutes Undergo clinical assessments at baseline and at week 6

The aim of this clinical trial is to investigate the effects of a dual-task-based exercise program on clinical outcomes in individuals with rotator cuff-related shoulder pain. The study will evaluate the effects of a dual-task exercise approach, in which physical exercises are performed concurrently with cognitive tasks, on pain, functional status, pain catastrophizing and kinesiophobia. These results will be compared with those of a standard shoulder rehabilitation program. The main questions this study aims to answer are: * Is there a difference in pain levels between individuals with rotator cuff-related shoulder pain who participate in a dual-task-based exercise program and those who participate in a standard exercise program? * Is there a difference between these two exercise approaches in terms of shoulder function and psychosocial factors? Participants will: * Participate in either a dual-task-based shoulder exercise program or a standard shoulder exercise program twice per week for 6 weeks. * Undergo clinical assessments at baseline, at week 6, and at week 12.

The goal of this clinical trial is to learn whether adding personalized contextual factors to an exercise program can improve pain and function in people with rotator cuff-related shoulder pain. This condition is a common cause of shoulder pain and can limit daily activities. The main questions this study aims to answer are: 1. Does a contextually enriched and individualized exercise program lead to greater improvement in upper-limb disability (measured by the QuickDASH questionnaire) compared with a contextually fixed program? 2. Does it lead to greater reductions in pain intensity (measured by the Numeric Pain Rating Scale) and greater improvements in autonomic nervous system regulation (measured by heart rate variability)? 3. Does it result in more favorable changes in psychosocial outcomes, exercise adherence, and therapeutic alliance? Researchers will compare two exercise programs to determine whether adding personalized contextual features enhances treatment effectiveness. One group will receive a standardized, evidence-based exercise program delivered in a fixed and neutral manner. The other group will receive the same exercise program with added personalized contextual elements, such as: * Preferred music and lighting * Choice between equivalent exercises (without changing exercise type or dosage) * Motivational feedback and supportive communication * Personalized progress tracking Both groups will: * Attend supervised exercise sessions twice per week for 12 weeks * Follow a structured home exercise program * Complete questionnaires assessing pain, function, and psychological factors * Undergo heart rate variability assessment to evaluate autonomic regulation * Be followed for 12 months after treatment The researchers expect that integrating personalized contextual elements into exercise therapy may enhance recovery, increase motivation, and improve long-term outcomes.

Shoulder pain from rotator cuff disorders is common, affecting function and quality of life. Many patients in orthopaedic clinics are diagnosed with these conditions. Most do not need surgery and are treated with pain relief and physiotherapy. However, long physiotherapy waitlists cause delays, and some patients do not achieve good outcomes. There is limited evidence to predict who will recover well with non-surgical care. A cohort study at Croom Orthopaedic Hospital is proposed to explore this. Patients assessed as suitable for non-surgical care by the shoulder physiotherapist will provide consent and complete questionnaires on pain, disability, quality of life, and personal factors like age and gender. They will continue with prescribed care and repeat the questionnaires after six months. This study will identify factors predicting successful outcomes, improving treatment programs to better meet patients' needs. It is funded by the Irish Research Council and led by Professors Karen McCreesh and Rose Galvin, UL, and Mr. Tristan Cassidy, Orthopaedic Consultant. Collaborators include Catriona Foley, shoulder specialist physiotherapist at Croom.

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.

The primary aim of this study is to determine the clinical effectiveness of patient education alone in individuals with rotator cuff-related shoulder pain and to identify which patient subgroups benefit more from this approach. In addition, the translation and cultural adaptation of the "Patient Knowledge Questionnaire (PKQ-RCRSP)" into Turkish will be carried out to measure the level of patient knowledge regarding patient education.

The primary objective of this clinical trial is to investigate the effect of a block of four specific virtual reality (VR) exercises on upper limb function, pain, kinesiophobia, and pain catastrophizing in individuals with rotator cuff-related shoulder pain (RCRSP). The secondary objective is to examine participants' tolerability of different VR interventions. Study Procedures: Participants will: * Attend a face-to-face assessment to confirm eligibility and receive a standardized pain neurophysiology education session (week 0). * Visit the clinic once weekly for four weeks to undergo the VR interventions and review pain education concepts (Weeks 5 to 8). * Complete online questionnaires evaluating upper limb function, kinesiophobia, pain, sense of presence, and cybersickness. Interventions Four VR interventions will be tested: * Unimanual distraction task with normal visual feedback * Bimanual distraction task with normal visual feedback * Unimanual reaching task with augmented visual feedback * Unimanual reaching task with diminished visual feedback Findings will guide clinicians in selecting the most effective VR interventions for shoulder impairment and assess the feasibility of implementing VR in a private physiotherapy clinic for individuals with RCRSP.

Subacromial pain syndrome (SPS) is one of the most common causes of shoulder pain, leading to significant disability and socioeconomic burden. Although percutaneous electrical nerve stimulation (PENS) targeting the suprascapular nerve (SN) has shown positive therapeutic outcomes, individual response to the intervention varies considerably. This study aims to develop a multivariable predictive model to estimate clinical response to SN-targeted PENS in patients with SPS. The model will be built using clinical, psychological, and neural mechanosensitivity variables. The goal is to enhance patient selection and guide personalized treatment strategies.

Work-related shoulder pain is a common problem with significant socio-economic repercussions. The impact of these disorders on workers is considerable, particularly in terms of pain, disability and reduced quality of life. Several occupational factors may explain the onset of these disorders, such as changes in the work environment, physical demands, psychosocial factors specific to the occupational context and the age of workers. The lack of quantitative measurement tools to assess the physical demands of work over an extended period of time is sorely felt. Recently, our team developed a wearable feedback device, similar to a watch worn on the arm, which measures shoulder movements and muscle activity, transforming this real-time data into clinical indicators. These indicators provide immediate feedback to workers, enabling them to better understand the physical demands of their tasks and adapt accordingly. If this device proves effective in reducing physical demands, it could become a valuable tool for guiding workplace assessments and interventions. However, this device has not yet been tested on workers with shoulder pain. For this reason, a two-part pilot study is needed to understand user needs, assess ease of use and the feasibility of implementing the device. The first component will consist of a pilot clinical trial involving 42 workers suffering from shoulder pain, divided into two groups: one group will use the feedback device for 2 weeks, while the other group will continue to work without intervention. The second phase will analyze the experience of participants who have used the device.

New recommendations regarding care pathways for the management of shoulder pain syndromes have recently been published. We aim to analyze and compare the existing care pathways and identify the most appropriate approaches for different patient profiles. Our primary objective is to compare pain levels and shoulder function one year after your initial consultation with your general practitioner for this episode. We also seek to assess which healthcare professionals you consult for your shoulder management, the treatments you receive (e.g., analgesics), and any imaging studies you undergo (if prescribed). We will send you notifications to remind you of the survey completion schedule and provide the link to access the questionnaire. Participation in this study requires your commitment and adherence to the timeline, as missing data may compromise the analysis of results. Non-participation in the study will not affect your current medical care.

As musculoskeletal disorders (MSKDs) reach epidemic proportions in Canada, access to the public health system for those who suffer from them is increasingly difficult. One of the main barriers is the delays to see a publicly funded health professional. New models of care must therefore be developed to ensure better access. We have previously shown that not all patients with a MSKD need to be closely followed by a health professional as for a large proportion of patients simply educating them is enough to resolve their MSKD. A stepped care model where education would be given first before deciding if patients need a more extensive follow-up should be explored. This project will compare the effectiveness of a Stepped Care Model to that of the two most widely used models of care: Usual Medical Care and Usual Rehabilitation Care. We think that a Stepped Care Model will be as effective to reduce functional limitations, but will lead to lower healthcare costs. Adults (n=369) with a MSKD will be randomly assigned to one of the intervention groups: Stepped Care, Usual Medical Care (physician-led intervention: e.g., advice/education, pharmacological pain management), or Usual Rehabilitation Care (physiotherapist-led intervention: e.g., advice/education, exercises). Participants in the Stepped Care Group will take part in two education sessions during the first 6 weeks. After 6 weeks, those who still have clinically important symptoms will receive follow-up rehabilitation interventions, while those who don't will be considered recovered and will have no further intervention. Primary (functional limitations) and secondary (e.g., pain, quality of life) outcomes will be assessed at baseline, and at 6, 12 and 24 weeks, and costs estimate will be established for each model of care. Knowing the urgent need for an overhaul of services to reduce wait times, the Stepped Care Model proposed could be a solution to improve access to health services without compromising quality of care.

The aim of this study is to evaluate the efficacy of 12 weeks of sensorimotor training with movement representation techniques for reducing pain intensity in people with rotator cuff related shoulder pain, relative to standard care. Besides, the secondary aim of this study is to explore the mechanisms underlying the effects of central mechanism treatment in people with rotator cuff related shoulder pain. A total of 122 older adults aged 50 or above with the presence of shoulder pain for more than three months will be recruited and randomized into 12-weeks of movement representation techniques with sensorimotor training vs. standard care. Shoulder pain and disability Index (SPADI), changes in primary motor cortex (M1) using brain MRI, changes in subacromial space using ultrasound imaging, Widespread Pain Index (WPI), Pain Catastrophising Scale (PCS), and Fear-avoidance Beliefs questionnaires (FABQ) will be assessed at baseline and 12-week post intervention.
