RESUMEN

OBJECTIVE: To systematically review the clinical efficacy (pain, function, quality of life) and safety of platelet-rich plasma (PRP) in the treatment of frozen shoulder through meta-analysis, and provide evidence-based medical evidence for the effectiveness of PRP in the treatment of frozen shoulder. METHODS: A search was conducted on international databases (Pubmed, Web of science, Embase) and Chinese databases (CNKI, Wanfang, VIP) to search the clinical studies on the efficacy of platelet-rich plasma in treating frozen shoulder (adhesive capsulitis/periarthritis/50 shoulder) and their corresponding references published from inception until January 2024. Thoroughly excluded literature not meeting the predetermined inclusion criteria, extracted relevant data from the literature, and input it into RevMan5.4 for meta-analysis. RESULTS: This study ultimately included 14 RCTs, with a total of 1024 patients. The results showed that PRP has significant advantages compared with control groups in VAS (mean difference (MD) =-0.38, 95% confidence interval(CI)(-0.73, -0.03), P = 0.03), UCLA (MD = 3.31, 95% CI (1.02,5.60),P = 0.005), DASH (MD = -4.94,95% CI (-9.34, -0.53),P = 0.03), SPADI (SPADI Total: MD =-16.87, 95% CI (-22.84, -10.91), P < 0.00001; SPADI Pain: MD =-5.38, 95% CI (-7.80, -2.97), P < 0.0001; SPADI Disability: MD =-11.00, 95% CI (-13.61,-8.39), P < 0.00001), and the active and passive Range of Motion (active flexion: MD = 12.70, 95% CI (7.44, 17.95), P < 0.00001; passive flexion: MD = 9.47, 95% CI(3.80, 15.14), P = 0.001; active extension: MD = 3.45, 95% CI(2.39, 4.50), P < 0.00001; active abduction: MD = 13.54, 95% CI(8.42, 18.67), P < 0.00001; passive abduction: MD = 14.26, 95% CI (5.97, 22.56), P = 0.0008; active internal rotation: MD = 5.16, 95% CI (1.84, 8.48), P = 0.002; passive internal rotation: MD = 3.65, 95% CI(1.15, 6.15), P = 0.004; active external rotation: MD = 10.50, 95% CI(5.47, 15.53), P < 0.0001; passive external rotation: MD = 6.00, 95% CI (1.82, 10.19), P = 0.005) except passive extension (MD = 2.25, 95% CI (-0.77, 5.28), P = 0.14). In terms of safety, most studies reported no adverse effects, and only one study reported common complications of joint puncture such as swelling and pain after treatment in both PRP and control groups. Previous studies have shown a risk of osteonecrosis caused by corticosteroids. Therefore, the safety of PRP treatment is more reliable. CONCLUSION: The results showed that PRP was more durable and safer than corticosteroids and other control groups in the treatment of frozen shoulder. STUDY DESIGN: Systematic review. TRIAL REGISTRATION: PROSPERO CRD42022359444, date of registration: 22-09-2022.

RESUMEN

OBJECTIVE: To review the role of sacro-iliac magnetic resonance imaging (MRI) in the diagnosis of axial spondyloarthritis (AxSpA), with a focus on gender differences. METHODS: The experience of the authors and the results of an informal literature review are reported. RESULTS: Inflammatory changes of the sacro-iliac joint are the hallmark of AxSpA. Early, non-radiographic sacroiliitis may be diagnosed with MRI through the assessment of bone marrow edema (BMO) as well as concomitant structural damage. The MRI protocol should include three necessary sequences, i.e., fat-saturated T2-weighted sequences on two orthogonal planes, T1-weighted semi-coronal sequence, and fat-suppressed T1-weighted semi-coronal sequence. Inflammatory changes comprise required signs (BMO and/or osteitis) and additional signs, including synovitis (better defined as joint space enhancement), enthesitis, and capsulitis. Structural changes consist of erosions, sclerosis, fat metaplasia, and ankylosis. Due to mechanical axial strain, inflammatory changes in the sacro-iliac joint can be found in healthy individuals, runners, and patients with nonspecific low back pain. The prevalence of BMO is higher in women during pregnancy and postpartum, even 12 months after childbirth, but the extent and distribution of MRI findings may help in the differential diagnosis. Other challenges in the MRI diagnosis of sacroiliitis are subchondral T2 hyperintensity during developmental age, periarticular sclerosis in healthy subjects, or osteitis condensans ilii, and several pathological conditions that may mimic AxSpA, some of which are more frequently found in women. CONCLUSIONS: The described diagnostic challenges impose a multidisciplinary approach combining imaging findings with clinical and laboratory data.

RESUMEN

BACKGROUND: The aim of this study was to provide comprehensive and reliable evidence for the treatment of pain and motor function in patients with frozen shoulder (FS) with hydrodistension. METHODS: The research including randomized controlled trials (RCTs) for FS that compared hydrodistension with routine treatments to controls was searched and screened in the PubMed, Library of congress, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, China Science and Technology Journal Database. Constant-Murley score (CMS) for shoulder function and visual analog scale (VAS) for pain must be assessed. RevMan 5.3 software was used to evaluate the bias and quality of the included studies. RESULTS: We found that analgesic effects (MD: -1.07; 95% CI: -1.94 to -0.20; P < .00001; I2 = 99%) and function (MD: 8.54; 95% CI: 3.35 to 13.71; P < .00001; I2 = 97%) were better in the groups where hydrodistension plus routine treatments were used to treat FS compared to other interventions. CONCLUSION: The result suggests that hydrodistension is of great clinical significance in alleviating pain and improving function to patients with FS.

RESUMEN

Although frequently prescribed for frozen shoulder, it is not known if corticosteroid injections improve the course of frozen shoulder. This study aimed to assess the disease-modifying effects of an intra-articular corticosteroid administration at the freezing phase of frozen shoulder. Twenty-four Sprague-Dawley rats were divided into four groups. Their unilateral shoulders were immobilized for the first 3 days in all groups, followed by an intra-articular corticosteroid injection in Group A, an injection and the cessation of immobilization in Group B, no further intervention in Group C, and the cessation of immobilization in Group D. All rats were sacrificed in Week 3 of study, at which point the passive shoulder abduction angles were measured and the axillary recess tissues were retrieved for histological and Western blot analyses. The passive shoulder abduction angles at the time of sacrifice were 138° ± 8° (Group A), 146° ± 5° (Group B), 95° ± 11° (Group C), 132° ± 8° (Group D), and 158° ± 2° (Control). The histological assessments and Western blots showed greater fibrosis and inflammation in the groups that did not receive the corticosteroid injection (Groups C and D) compared to the corticosteroid-injected groups (Groups A and B). These findings demonstrate the anti-inflammatory and disease-modifying effects of corticosteroid injections during the freezing phase of frozen shoulder in an animal model.

RESUMEN

BACKGROUND: Many studies have investigated the association between hypothyroidism and frozen shoulder, but their findings have been inconsistent. Furthermore, earlier research has been primarily observational, which may introduce bias and does not establish a cause-and-effect relationship. To ascertain the causal association, we performed a two-sample bidirectional Mendelian randomization (MR) analysis. METHODS: We obtained data on "Hypothyroidism" and "Frozen Shoulder" from Summary-level Genome-Wide Association Studies (GWAS) datasets that have been published. The information came from European population samples. The primary analysis utilized the inverse-variance weighted (IVW) method. Additionally, a sensitivity analysis was conducted to assess the robustness of the results. RESULTS: We ultimately chose 39 SNPs as IVs for the final analysis. The results of the two MR methods we utilized in the investigation indicated that a possible causal relationship between hypothyroidism and frozen shoulder. The most significant analytical outcome demonstrated an odds ratio (OR) of 1.0577 (95% Confidence Interval (CI):1.0057-1.1123), P = 0.029, using the IVW approach. Furthermore, using the MR Egger method as a supplementary analytical outcome showed an OR of 1.1608 (95% CI:1.0318-1.3060), P = 0.017. Furthermore, the results of our sensitivity analysis indicate that there is no heterogeneity or pleiotropy in our MR analysis. In the reverse Mendelian analysis, no causal relationship was found between frozen shoulders and hypothyroidism. CONCLUSION: Our MR analysis suggests that there may be a causal relationship between hypothyroidism and frozen shoulder.

RESUMEN

OBJECTIVE: To summarize current insights on the immune pathology of bursitis caused by rheumatic inflammatory diseases, degenerative conditions, or mechanical stress and identify knowledge gaps in this field. Data on tenosynovitis pathology was included for comparison. METHODS: We performed a systematic review encompassing an electronic database search of all published literatures in PubMed/MEDLINE from inception to February 13, 2023, investigating the immunological changes occurring in the bursa of patients with inflammatory rheumatic diseases, degenerative conditions or mechanical stress (e.g., impingement syndrome). RESULTS: Thirty-two articles provided data on the immune pathology of bursal tissue inflammation were identified. Histological and immunological perturbations included alterations of tissue morphology, infiltration of macrophages and some T cells, and enhanced expression of proinflammatory cytokines, such as interleukin (IL)-6, IL-1ß and tumor necrosis factor alpha (TNF-α). These changes were described for all three underlying causes, although studies on bursitis associated with rheumatic inflammatory diseases were rare. Fibrosis was only reported in subacromial bursitis caused by mechanical stress within our included studies. CONCLUSION: Current insights on bursitis were outdated and studies on bursitis associated with rheumatic inflammatory diseases are particularly lacking. Substantial overlap of enhanced expression of IL-6, IL-1ß, TNF-α and infiltrating macrophages were found in bursitis irrespective of the underlying cause. In depth investigation on bursitis such as high throughput multi-omics are urgently needed to guide disease-specific therapeutic management.

RESUMEN

Patellar tuberculosis (TB) is a rare manifestation of musculoskeletal tuberculosis, accounting for a small proportion of cases. This case report presents a detailed analysis of a female patient in her early 30s who presented with isolated TB of the patella without concurrent pulmonary involvement. The patient received antitubercular chemotherapy, consisting of a 4-month intensive phase followed by an 8-month continuation phase. This case report underscores the rarity and diagnostic complexities associated with patellar TB. The condition often presents with non-specific symptoms, often mimicking prepatellar bursitis, necessitating a high level of clinical suspicion, particularly in patients from the endemic areas. Radiographic imaging and histopathological examination play crucial roles in establishing an accurate diagnosis. Antitubercular chemotherapy forms the cornerstone of treatment while surgical intervention is reserved for cases of extensive bone destruction or treatment failure.

RESUMEN

BACKGROUND: Adhesive capsulitis (AC) causes a variety of symptoms, including but not limited to pain, stiffness, and a gradual restriction of active and passive range of motion (ROM). The coracohumeral ligament (CHL) plays an important role in this disease process, and percutaneous CHL release (PCHLR) has demonstrated efficacy in treating manifestations of this disorder that are refractory to pain medication, physical therapy, and local injections. Our previous study demonstrated one-year efficacy and durability, and this study examines 2-year data from our original randomized control crossover cohort. OBJECTIVE: To highlight the importance of extended follow-ups evaluating PCHLR's efficacy in AC management. STUDY DESIGN: A prospective, randomized, controlled, cross-over trial. SETTING: An academic medical center. METHODS: Patients with AC refractory to oral medication, physiotherapy, and at least one local injection were included in our original study. In all, there were initially 40 patients (46 shoulders), including 6 patients who underwent bilateral PCHLR using the Tenex® system. In this prospective study, 2 groups, the experiment group (scheduled to receive PCHLR) and the control group (scheduled to receive a local anesthetic in the coracohumeral ligament [LACHL]) were determined through 2-to-1 block randomization. Of these 46 shoulders initially treated, 39 remained in the study at one year. Twenty-six of the 39 shoulders were assigned to the PCHLR group whereas 13 were assigned to the LACHL group. Nine out of 13 shoulders in the LACHL group crossed over to the PCHLR group. Ultimately, 31 shoulders remained in the PCHLR group for 2-year analysis. The effectiveness of these interventions was assessed using a variety of parameters. Pain scores, ROM, and the Oxford Shoulder Score (OSS) were evaluated before the procedure and at one-year and 2-year follow-up visits. RESULTS: In this 2-year follow-up study, a total of 31 shoulders were sampled, comprising 22 women and 5 men, with 4 patients undergoing bilateral procedures. The mean age of the patients was 65 years (± 11.48). Patients' mean body mass index (BMI) was 36.33 (± 6.55), and the mean CHL thickness was 38.5 (± 3.45). Osteoarthritis was present in 11 cases. The mean follow-up period for the study was 29.7 months (± 6.39). The baseline mean external rotation was 30° (± 8), which increased to 62° (± 18) at one year and 53° (± 18) at 2 years. The baseline mean abduction was 60° (± 16), which improved to 77° (± 21) at one year and 68° (± 20) at 2 years. The median NRS decreased from 8 (IQR: 8, 9) at baseline to 3 (IQR: 2, 7) at one year and 5 (IQR: 2, 7) at 2 years. The baseline median OSS was 7 (IQR: 3, 10), which increased to 32 at one year and 22 (IQR: 15, 35) at 2 years. LIMITATIONS: The present investigation has a limited sample size of patients who have ROM impairment caused by CHL thickening. CONCLUSIONS: While the algorithm for AC care has seen little change for several decades, the authors suggest that PCHLR is a safe, durable, and effective option for cases of AC that are refractory to traditional management.

RESUMEN

Adhesive Capsulitis of the shoulder is a painful pathology limiting shoulder movements, commonly known as "Frozen Shoulder". Since this pathology limits movement, it is important to make an early diagnosis. Diagnosing capsulitis relies on clinical assessment, although diagnostic imaging, such as Magnetic Resonance Imaging, can provide predictive or supportive information for specific characteristic signs. However, its diagnosis is not so simple nor so immediate, indeed it remains a difficult topic for many general radiologists and expert musculoskeletal radiologists. This study aims to investigate whether it is possible to use disease signs within a medical image to automatically diagnose Adhesive Capsulitis. To this purpose, we propose an automatic Model Checking-based approach to quickly diagnose the Adhesive Capsulitis taking as input the radiomic feature values from the medical images. Furthermore, we compare the performance achieved by our method with diagnostic results obtained by professional radiologists with different levels of experience. To the best of our knowledge, this is the first method for the automatic diagnosis of Adhesive Capsulitis of the Shoulder.

RESUMEN

This study aims to explore the risk factors associated with frozen shoulder (FS) and develop a predictive model for diagnosing FS, in order to facilitate early detection of the condition. A total of 103 patients diagnosed with FS and admitted to the Department of Joint Surgery at Suining Central Hospital between October 2021 and October 2023 were consecutively included in the study. Additionally, 309 individuals without shoulder joint diseases, matched for age and gender, who visited the department during the same time, were included as the control group.The complete recording of clinical data for all patients was followed by the utilization of statistical tests such as the Mann-Whitney U test, sample t test, and chi-square test to compare different groups. Additionally, multivariate binary logistic regression analysis was employed to identify risk factors associated with the occurrence of FS in patients, leading to the establishment of a prediction model and derivation of a simplified equation. The diagnostic effectiveness of individual indicators and prediction models was assessed through the use of receiver operating characteristic (ROC) curve analysis. In the sample of 103 individuals, 35 were identified as male and 68 as female, with an average age range of 40-70 years (mean age: 54.20 ± 6.82 years). The analysis conducted between different groups revealed that individuals with a low body mass index (BMI), in conjunction with other factors such as diabetes, cervical spondylosis, atherosclerosis, and hyperlipidemia, were more susceptible to developing FS. Logistic regression analysis further indicated that low BMI, diabetes, cervical spondylosis, and hyperlipidemia were significant risk factors for the occurrence of FS. These variables were subsequently incorporated into a predictive model, resulting in the creation of a simplified equation.The ROC curve demonstrated that the combined indicators in the predictive model exhibited superior diagnostic efficacy compared to single indicators, as evidenced by an area under the curve of 0.787, sensitivity of 62.1%, and specificity of 82.2%. Low BMI, diabetes, cervical spondylosis, and hyperlipidemia are significant risk factors associated with the occurrence of FS. Moreover, the utilization of a prediction model has demonstrated superior capability in forecasting the likelihood of FS compared to relying solely on individual indicators. This finding holds potential in offering valuable insights for the early diagnosis of FS.

RESUMEN

Background: Mounting evidence suggests a connection between inflammatory cytokines and adhesive capsulitis (AC). However, the specific systemic inflammatory cytokines contributing to AC have not been clearly identified. This study employed Mendelian randomization (MR) to explore the causal relationships between 41 inflammatory cytokines and AC. Methods: In this bidirectional, two-sample MR analysis, genetic variations associated with AC were derived from a comprehensive genome-wide association study (GWAS). The inflammatory cytokines data were sourced from a GWAS summary involving 8,293 healthy participants. The primary MR method employed was inverse variance weighting, supplemented by MR-Egger, weighted median, and MR-pleiotropy residual sum and outlier for sensitivity analysis. Heterogeneity was assessed using Cochran's Q test, and the MR results were validated using the leave-one-out method. Results: Elevated levels of interferon gamma-induced protein 10 (IP-10) (odds ratio (OR) = 1.086, 95% confidence interval (CI) = 1.002-1.178) and regulated on activation, normal T cell expressed and secreted (RANTES) (OR = 1.107, 95% CI = 1.026-1.195) were linked to an increased risk of AC. Increased levels of stromal cell-derived factor-1 alpha (SDF-1α) (OR = 0.879, 95% CI = 0.793-0.974) and tumor necrosis factor-alpha (TNF-α) (OR = 0.911, 95% CI = 0.831-0.999) were associated with a reduced AC risk. Moreover, genetically predicted AC exhibited associations with elevated cutaneous T cell attracting (CTACK) levels (OR = 1.202, 95% CI = 1.007-1.435) and diminished levels of interleukin-17 (IL-17) (OR = 0.678, 95% CI = 0.518-0.888) and interleukin-5 (IL-5) (OR = 0.786, 95% CI = 0.654-0.944), as confirmed through inverse-variance weighted (IVW) methods. Conclusion: The present study successfully establishes a causal association between genetically proxied circulating levels of IP-10, RANTES, SDF-1α, and TNF-α and the risk of AC. Additionally, AC contributes to an increase in CTACK and a decrease in IL-17 and IL-5. This significant finding not only enhances the understanding of the pathogenesis of AC but also holds promise for the development of effective clinical management strategies.

RESUMEN

We investigated the effect of robotic assistance in a postoperative change in hip offset and the incidence of trochanteric bursitis among total hip arthroplasty (THA) patients. As part of a retrospective study of a consecutive series of patients over a 3-year period, 211 patients (102 traditional; 109 robotic) between 2013 and 2016 who underwent posterior-lateral THA were reviewed. Hip offset was measured on preoperative and postoperative anterior-posterior (AP) pelvis radiographs. The absolute change in total hip offset was higher in patients undergoing non-robotic THA than in patients undergoing robotic THA (5.98 ± 4.47 mm vs 4.33 ± 3.98 mm; p = 0.008). The rate of symptomatic trochanteric bursitis (p = 0.02) and cortisone injection was higher in non-robotic THA patients than in robotic THA patients (p = 0.002). Robotic arm-assisted THA is associated with a decreased postoperative change in hip offset, incidence of symptomatic trochanteric bursitis, and bursal steroid injections.

RESUMEN

Objective: To compare the mid-term effectiveness of arthroscopic shoulder capsular release combined with acromiohumeral distance (AHD) restoration in the treatment of diabetic secondary stiff shoulder and primary frozen shoulder. Methods: A retrospective analysis was conducted on clinical data of 22 patients with diabetic secondary stiff shoulder (group A) and 33 patients with primary frozen shoulder (group B), who underwent arthroscopic 270° capsular release combined with AHD restoration treatment. There was no significant difference between the two groups in gender, age, affected side, disease duration, and preoperative AHD, shoulder flexion range of motion, abduction range of motion, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS) score, and Constant score ( P>0.05). Only the difference in the internal rotation cone rank and external rotation range of motion between the two groups showed significant differences ( P<0.05). The improvement in shoulder pain and function was evaluated by using VAS score, ASES score, and Constant score before operation and at last follow-up. Active flexion, abduction, external rotation range of motion, and internal rotation cone rank were recorded and compared. AHD was measured on X-ray films. Results: All patients were followed up 24-92 months (median, 57 months). There was no significant difference in follow-up time between group A and group B ( P>0.05). No fractures or glenoid labrum tears occurred during operation, all incisions healed by first intention, and no complication such as wound infection or nerve injury was observed during the follow-up. At last follow-up, there were significant improvements in active flexion, abduction, external rotation range of motion, internal rotation cone rank, AHD, VAS score, ASES score, and Constant score when compared with preoperative ones in both groups ( P<0.05). Except for the difference in change in external rotation range of motion, which had significant difference between the two groups ( P<0.05), there was no significant difference in other indicators between the two groups ( P>0.05). Conclusion: Arthroscopic capsular release combined with AHD restoration can achieve good mid-term effectiveness in the treatment of diabetic secondary stiff shoulder and primary frozen shoulder. However, the improvement in external rotation range of motion is more significant in the patients with diabetic secondary stiff shoulder.

RESUMEN

OBJECTIVE: Frozen Shoulder (FS) is a musculoskeletal pathology that leads to disability, functional decline, and a worsening in quality of life. Physiotherapists are the primary professionals involved in the treatment of FS, and it is essential to determine if their practice aligns with evidence-based suggestions. AIM: The aim is to assess the knowledge, skills, and operational strategies of Italian physiotherapists regarding FS and compare them with the existing literature. METHODS: A web-based, anonymous, and voluntary cross-sectional survey was developed and administered to Italian physiotherapists to evaluate their clinical practices. RESULTS: A total of 501 physiotherapists (38.5% female), completed the survey. More than half were under 35 years old (67.8%), declared working in private practice settings or being self-employed (57.1%), and were primarily engaged with musculoskeletal patients (81.8%). For subjects with FS at their first access, 21.4% identified X-rays as the most useful imaging technique to recognize pathologies beyond rehabilitation competence. In terms of general management, the majority reported working with an orthopaedic or physiatrist (47.5%) or in a multidisciplinary team (33.5%). Regarding manual therapy techniques, 63.3% of physiotherapists preferred intense degree mobilization, posterior direction, and moderate pain at the end of the range of motion for low irritable/high stiffness FS; however, there is a lack of consensus for managing very irritable/low stiffness FS. The majority of physiotherapists (57.7%) concurred that stretching improves the balance between metalloproteinase and its inhibitors. Additionally, 48.3% of physiotherapists selected mobile phone videos and messages to improve patients' compliance with exercises at home and for motivational/educational purposes. DISCUSSION AND CONCLUSION: The clinical practices of Italian physiotherapists in FS subjects sometimes deviate from evidence-based recommendations. While some discrepancies may be attributed to the existing uncertainties in the literature regarding knowledge and management strategies for FS patients, the authors recommend a stronger adherence to evidence-based practice.

RESUMEN

Spinal diseases and frozen shoulder are prevalent health problems in Asian populations. Early assessment and treatment are very important to prevent the disease from getting worse and reduce pain. In the field of computer vision, it is a challenging problem to assess the range of motion. In order to realize efficient, real-time and accurate assessment of the range of motion, an assessment system combining MediaPipe and YOLOv5 technologies was proposed in this study. On this basis, Convolutional Block Attention Module (CBAM) is introduced into the YOLOv5 target detection model, which can enhance the extraction of feature information, suppress background interference, and improve the generalization ability of the model. In order to meet the requirements of large-scale computing, a client/server (C/S) framework structure is adopted. The evaluation results can be obtained quickly after the client uploads the image data, providing a convenient and practical solution. In addition, a game of "Picking Bayberries" was developed as an auxiliary treatment method to provide patients with interesting rehabilitation training.

RESUMEN

BACKGROUND Frozen shoulder with limited range of motion is a common and debilitating condition that occurs on the affected side following a stroke. The effectiveness of therapy was reported to be negatively correlated with the complexity of pathogenesis. Prolotherapy involves injection into the joint of a small amount of irritant, such as dextrose, which enhances tissue strength and facilitates healing by targeting joint spaces. The treatment is used to relieve pain. This report describes the effects of combined prolotherapy and physical therapy in a 60-year-old man with left shoulder pain and limited range of motion (frozen shoulder) following a hemiplegic stroke. CASE REPORT A 60-year-old man had left shoulder pain and limited ROM for 9 months, which disrupted daily life, with a NRS of 7 and a DASH score of 58.3%. The patient had an ischemic stroke 1 year ago, with left extremity weakness. On physical examination, joint active ROM was significantly restricted and the joint was tender upon palpation. Therapy is carried out using prolotherapy combined with exercise and physical therapy for 6 weeks. At the 6-week follow-up, he had good outcomes for pain relief, increasing ROM, and quality of life. CONCLUSIONS The use of prolotherapy with physical therapy may be an effective treatment for painful frozen shoulder following a hemiplegic stroke.

RESUMEN

BACKGROUND: Adhesive capsulitis (AC), more commonly known as "frozen shoulder", is a painful shoulder condition. The illness progresses through three phases: freezing, frozen and thawing. A gold standard treatment for adhesive capsulitis is not defined. The goal of any treatment is to reduce pain and restore shoulder movement. OBJECTIVE: Objective of the present study is to evaluate the efficacy of gleno-humeral hydrodistension associated with physical therapy in patients with diagnosed adhesive capsulitis comparing the outcomes in term of pain and range of motion in patients with a phase 1 and a phase 2 disease. METHOD: Between January 2022 and April 2023, We evaluated 87 patients with adhesive capsulitis, 47 were excluded for others concomitant pathologies, finally 40 patients were enrolled for the study, of whom 23 had capsulitis in stage 1 and 17 in stage 2. Patients were evaluated at baseline and at 2, 4 and 6 months after infiltration recording range of motion in all planes, pain and functionality scores. RESULTS: A significant improvement was recorded in shoulder range of motion in all planes with the except of extension in both groups. Phase 2 patients were able to regain shoulder range of motion in all planes except internal rotation which was recovered with more difficulty. Pain and functionality scores improved significantly between baseline and follow-up visits. CONCLUSION: Ultrasound-assisted hydrodistention of the glenohumeral joint combined with targeted exercise has been successful in improving pain relief, reducing disability, and increasing range of motion in subjects with stage 1 and 2 adhesive capsulitis, especially if diagnosed before phase 2 (when the range of motion is completely reduced).
