Benefits and limitations of isokinetic force assessments in swimmer's shoulders: A systematic review.

OBJECTIVE: To indicate the benefits and limitations of the isokinetic test results for the performance of the main shoulder joint movements in swimmers, considering the different competitive levels, swimming techniques, race distances, and sex. METHODS: Search on the PubMed, CENTRAL, Medline, LILACS, and SCOPUS databases for the oldest records up to October 2022. Risk of bias, methodological quality, and level of evidence were evaluated based on the NHLBI checklist. RESULTS: 29 articles met the criteria and were included in this study. The quality analysis classified three as "good" and 26 as "regular", with a KAPPA index of 0.87. The main benefits found involved assessments of the clinical condition of the shoulder joint complex, relationships with performance, and reliability studies. The limitations found point to the participant's positioning in the instrument, use of angular velocity above 180°/s, and sample size. CONCLUSION: The use of the isokinetic dynamometer allows verifying the levels of strength, endurance, balance, and asymmetries among swimmers of different techniques, distances, competitive levels, and sex. Thus, it helps in the analysis and monitoring of the clinical conditions of swimmers' shoulder joints, contributing to the decision-making process of physiotherapists and coaches.

Shoulder pain management strategies and early functional outcome after arthroscopic rotator cuff tear repair. A randomized controlled study.

BACKGROUND: The management of acute postoperative pain after rotator cuff surgery can be challenging. To our knowledge, there are no data available in the literature correlating satisfactory pain control with improvement in terms of function. The purposes of the present study were to evaluate: 1) pain pattern after arthroscopic rotator cuff repair in patients operated with two different techniques (transosseous vs transosseous equivalent); 2) safety/efficacy of three different pharmacological pain control strategies; 3) possible relationship between a correct shoulder pain management protocol in the early post-operative period and patients' functional improvement. METHODS: 114 patients underwent rotator cuff tear repair, either with a Transosseus or a Transosseus equivalent technique. 62 (54%) were male and 52 (46%) were female. The average age was 59 ± 9 years. They were randomly assigned into three different pain management protocols: Paracetamol as needed (max 3 tablets/day) for 1 week (Protocol A), Paracetamol + Codein 1 tablet three times per day for 7 days (Protocol B), or Paracetamol + Ibuprofen 1 tablet two times per day for 7 days (Protocol C). Immediate passive mobilization of the operated shoulder was allowed. VAS and Passive Flexion values were recorded at 7 (T1), 15 (T2) and 30 (T3) days post-surgery. DASH values were recorded at 90 days post-surgery. All patients were asked to register any kind of signs/symptoms that may appear during drug assumption according to each pain management protocols. RESULTS: All the pain management protocols administered were well tolerated by all the study population, and no adverse signs/symptoms were highlighted during drug assumption. Pain pattern: in both surgical techniques, patients within Protocol A were associated with worst results in terms of mean VAS at each time point examined when compared to Protocol B and C (p < 0,05). In patients within Protocol A, no statistically significant differences were found at each point time examined comparing the two surgical techniques, with the exception of T2, where the TO was associated with an higher VAS value than TOE (p < 0.05). No differences were highlighted in Protocol B and C when comparing the values between two surgical techniques. ROM: in both surgical techniques, patients within Protocol A were associated with worst results in terms of mean PROM at each time point examined when compared to Protocol B and C (p < 0,05). In the TO group, patients within Protocol B had better PROM values at T1 (p < 0,05) and T2 (p < 0,05) compared to Protocol C, but no differences were highlighted at T3. In the TOE group, no statistically significant differences were found between patients within Protocol B and C at each time point examined. DASH: In the TO group, no statistically significant differences were found regarding the DASH values comparing Protocol B vs Protocol C, but they were highlighted comparing the values between Protocol A and Protocol B (p < 0,05), and between Protocol A and Protocol C (p < 0,05). Similar results were recorded in the TOE group. CONCLUSION: Post-operative pain is influenced by the surgical technique used being transosseous more painful in the first 15 days after surgery. Oral anti-inflammatory drugs are a feasible strategy to appropriately control post-operative pain. An association between Paracetamol and either Codein or Ibuprofen can lead to better outcomes in terms of VAS reduction and early recovery of passive ROM.

Shoulder and scapulothoracic impairments in women with breast cancer-related lymphedema in the upper limb: A cross-sectional study shoulder and breast cancer-related lymphedema.

INTRODUCTION: Lymphedema in the upper limb as a complication of breast cancer may lead to shoulder pain and dysfunctions. OBJECTIVE: To compare the scapular positioning, the shoulder range of motion, and muscle strength among women undergoing treatment for breast cancer with and without lymphedema and a control group. METHODS: This cross-sectional study evaluated women undergoing treatment for breast cancer (N = 25) and without lymphedema (N = 25), and a control group (N = 25). Static scapular positions and shoulder range of motion were measured by using an inclinometer. The shoulder and periscapular muscle strength were measured by using a hand-held dynamometer and the Disabilities of the Arm, Shoulder, and Hand Questionnaire was applied. Linear regression of the mixed effects model was used to compare the groups. RESULTS: Both groups of mastectomized women had reduced shoulder range of motion, scapular upward rotation, and muscle strength for shoulder and periscapular muscles compared to the control group. Also, women undergoing treatment for breast cancer with lymphedema had reduced shoulder range of motion, scapular upward rotation, increased anterior tilt, reduced muscle strength of the upper trapezius, and greater upper limb disability compared to women without lymphedema. CONCLUSION: Women undergoing treatment for breast cancer with lymphedema had even greater shoulder and scapulothoracic impairments when compared to the control group and women without lymphedema.

Electromyographic analysis of shoulder-complex muscles performing overhead presses with dumbbell, kettlebell, and bottom-up kettlebell.

INTRODUCTION: Kettlebell exercises, specifically the bottom-up grip, have become increasingly popular in training programs. The purpose of this research was to determine if a bottom-up kettlebell grip favorably alters the electromyography (EMG), activity in the medial deltoid (MD), serratus anterior (SA), and lower trapezius (LT), muscles compared to using a dumbbell or traditional kettlebell grip during overhead shoulder presses. METHODS: Twenty-eight healthy, male, Division III collegiate baseball players (mean age = 19.8 ± 1.28 years) performed five overhead presses of equal weight, 11.34 kg (25 lbs), using a dumbbell (DB), kettlebell w/traditional grip (KB), and kettlebell held with a bottom-up grip (KBU). RESULTS: For the MD, there was significantly greater EMG activity using the DB compared to KBU, but no significant differences between the DB and KB, or KB and KBU. For the SA, greater EMG activity was noted using the KBU compared to KB, and KBU compared to DB, but no differences between KB and DB. For the LT, greater EMG activity was noted using the DB compared to KB, but no differences between DB and KBU, or KB and KBU. CONCLUSION: The KBU press only elicited greater EMG activity in the SA. The DB elicited greater EMG activity in both the MD and LT. Shoulder-complex EMG activity varies with different types of overhead presses using equivalent loads.

Shoulder kinetic during pitching in baseball players with scapular dyskinesis.

INTRODUCTION: Shoulder injuries in baseball players cause excessive shoulder load during pitching and scapular dyskinesis (SD). However, the characteristics of pitching kinetics in the shoulder joint with SD are unclear. This study aimed to investigate the effect of SD on pitching kinetics in the shoulder joint of baseball players. METHOD: Seventy-two college and independent league baseball players participated in the study. The pitching motion was measured using an 18-camera motion-capture system. SD was classified into four types (I-IV) using the scapular dyskinesis test (SDT). The pitching kinetics data were analyzed. RESULTS: The agreement of SD in this study was 56/72 (77.8%). SD were classified into 31 abnormal group (type I-Ⅲ) and 25 control group (type Ⅳ). Three participants with measurement failure during the pitching motion analysis were excluded from the analysis. The abnormal group showed a larger maximum value of the glenohumeral normalized anterior joint force than the control group. CONCLUSIONS: These results suggest that an increase in GH anterior force during pitching causes an excessive increase in external rotation of the GH with an insufficient posterior tilt of the scapula with SD. Therefore, baseball pitching with SD may involve shoulder injuries owing to excessive shoulder load during pitching.

Reliability of isokinetic decay slope is superior to using fatigue indices for shoulder horizontal abduction.

INTRODUCTION: Reliable and valid measurements for shoulder muscular endurance should be available for clinical use. The posterior shoulder endurance test offers a potential clinical assessment, but its construct validity isn't available. Since a criterion measure of muscular endurance is not available, this study's purpose was to determine a reliable method for testing shoulder muscular endurance using an isokinetic dynamometer. METHODS: The test-retest reliability, standard error measurement, and minimal detectable change were calculated on four different paradigms to quantify muscular fatigue using two isokinetic speeds (60°sec-1,180°sec-1). Calculation paradigms included peak torque fatigue index (FI), average torque FI, area-under-the-curve FI, and peak torque decay slope. Testing occurred on two days. Repeated measures analysis of variance compared the two peak torque decay slopes across both testing days. RESULTS: Superior reliability was found within the decay slope measurements at both 60°sec-1 (ICC = 0.941) and 180°sec-1 (ICC = 0.764) speeds, with the 60°sec-1 decay slope being the highest reliability between the two angular velocities. There was a greater amount of fatigue in the 60°sec-1 decay slope compared to the 180°sec-1 decay slope. CONCLUSION: Using the decay slope of isokinetic shoulder horizontal abduction at 60°sec-1 is a reliable method to validate other muscular endurance clinical measures. Rehabilitation specialists should utilize the decay slope of the isokinetic dynamometry to monitor responsiveness.

Is there 'trustworthy' evidence for using manual therapy to treat patients with shoulder dysfunction?: A systematic review.

The primary objective of this review was to create a 'trustworthy,' living systematic review and meta-analysis for the application of manual therapy interventions in treating patients with shoulder dysfunction. Included studies were English-language randomized controlled trials published between 1/1/2010 and 8/3/2023, with searches performed in: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), CINHAL, ProQuest Nursing & Allied Health, EBSCO Medline, and PEDro. The population of focus included adults 18 years and older with musculoskeletal impairments related to shoulder dysfunction. Our primary outcomes included pain and region-specific outcome measures. We excluded trials, including participants having shoulder dysfunction resulting from surgery, radicular pain, instability/dislocation, fracture, lymphedema, and radiation. Our screening methodology was based upon a previously published 'trustworthy' systematic review protocol. This included the application of our PICOTS criteria in addition to screening for prospective clinical trial registration and following of prospective intent, as well as assessment of PEDro scores, risk-of-bias ratings, GRADE scoring, and examination of confidence in estimated effects. Twenty-six randomized controlled trials met our PICOTS criteria; however, only 15 of these were registered. Only three were registered prospectively. Two of these did not have discussions and conclusions that aligned with their primary outcome. The remaining single study was found to have a high risk-of-bias, meaning the remainder of the protocol could not be employed and that no randomized controlled trials could undergo further assessment or meta-analysis. The results of this systematic review indicate there are no 'trustworthy' randomized controlled trials examining the effectiveness of manual therapy interventions for the treatment of patients with shoulder dysfunction, as defined by the prospectively established methodology. Therefore, these findings signal that creating a 'trustworthy,' living systematic review on this clinically relevant topic is not yet possible due to a lack of 'trustworthy' randomized controlled trials.

Clinical effect of acupoint application with turmeric blistering moxibustion plaster on post-stroke hemiplegic shoulder pain. / 姜黄天灸膏穴位贴敷治疗脑卒中偏瘫肩痛临床疗效观察.

OBJECTIVES: To observe the effects of acupoint application with turmeric blistering moxibustion plaster on pain, shoulder range of motion (ROM) and upper limb motor function in the patients with post-stroke hemiplegic shoulder pain (PSHSP). METHODS: Eighty-two patients with PSHSP were randomly divided into an observation group (41 cases, 1 case was eliminated, 4 cases dropped out) and a control group (41 cases, 2 cases were eliminated and 2 cases dropped out). The routine treatment, nursing care and rehabilitation training were performed in the control group. On the basis of the intervention as the control group, in the observation group, the turmeric blistering moxibustion plaster was applied to bilateral ashi points, Jianyu (LI 15), Jianliao (TE 14), Binao (LI 14), Shousanli (LI 10) and Hegu (LI 4), once a day, remained for 6 hours each time. This moxibustion therapy was operated 5 times weekly, one course of treatment consisted of 2 weeks and 2 courses were required. Separately, before treatment and after 2 and 4 weeks of treatment, the score of visual analogue scale (VAS), shoulder ROM and the score of upper limbs in Fugl-Meyer assessment (U-FMA) were observed in the two groups. RESULTS: VAS scores were lower (P<0.05), ROM in shoulder flexion, abduction, internal rotation and external rotation was larger (P<0.05), and U-FMA scores were higher (P<0.05) after 2 and 4 weeks of treatment when compared with those before treatment in the two groups. After 4 weeks of treatment, VAS score decreased (P<0.05), and ROM in shoulder flexion, abduction, internal rotation, external rotation and U-FMA score increased (P<0.05) in comparison with those after 2 weeks of treatment in either group. In the observation group, VAS scores were dropped (P<0.05) after 2 and 4 weeks of treatment respectively, and ROM of shoulder flexion and abduction enlarged after 2 weeks of treatment (P<0.05) when compared with those in the control group. After 4 weeks of treatment, ROM in shoulder flexion, abduction, internal rotation and external rotation in the observation group was larger (P<0.05) and U-FMA score was higher (P<0.05) than those in the control group. CONCLUSIONS: Acupoint application with turmeric blistering moxibustion plaster may effectively reduce the degree of shoulder pain and improve the shoulder range of motion and the upper limb motor function in the patients with post-stroke hemiplegic shoulder pain.

Ischemic compression associated with joint mobilization does not promote additional clinical effects in individuals with rotator cuff related shoulder pain: A randomized clinical trial.

OBJECTIVE: The objective of this study was to verify which are the additional effects of the ischemic compression (IC) technique associated with joint mobilization techniques on pain, morphological aspects of myofascial trigger points (MTrPs), function, and psychological aspects in individuals with rotator cuff-related shoulder pain (RCRSP). METHODS: Sixty individuals with RCRSP were randomly allocated intervention sessions the Mobilization Group (MG, n = 20), only joint mobilizations of the shoulder complex; intervention sessions Compression Group (CG, n = 20), with the same mobilizations associated with the IC over MTrPs; and Placebo Group (PG, n = 20), with the same mobilizations associated with placebo of IC. All interventions performed 2 per week, for 6-weeks. Pain was assessed by Visual Analogue Scale and function by the Disabilities of the Arm, Shoulder and Hand questionnaire. The kinesiophobia, pain catastrophizing, perception of improvement, mobility, pain threshold and area the MTrPs were also evaluated at baseline (week-0), after 6-weeks and after 10-weeks. RESULTS: There were no between-group difference in pain: CG-MG 0.8 (95% CI 0.4 to 1.2), CG-PG 0.5 (95% CI 0.0 to 0.9), MG-PG -0.3 (95% CI -0.8 to 0.1) after 6-weeks and CG-MG 0.1 (95% CI -0.2 to 0.5), CG-PG -0.7 (95% CI -0.9 to -0,4), MG-PG -0,8 (95% CI -1.07 to 0.5) at 10-weeks. Similar effects were observed on function, characteristics of MTrPs and psychological aspects. CONCLUSION: The IC technique on the MTrPs of the upper trapezius muscle associated with joint mobilization techniques has no additional effect on pain in individuals with RCRSP. TRIAL REGISTRATION: RBR-44v8y7.

Surface electromyography analysis of core stabilizing muscles during isometric shoulder contractions in athletes with low back pain.

BACKGROUND: The study was carried out in the athletes with and without Low Back Pain (LBP) to determine the surface electromyography activity of core stabilizing muscles while performing isometric shoulder and trunk contractions. STUDY DESIGN: Cross-sectional study. METHODS: This study enlisted the participation of 40 athletes. Group A included 20 athletes (18 males and 2 females) without LBP, and Group B included 20 athletes (12 males and 8 females) with LBP. Athletes with LBP were assessed using the Modified Oswestry Disability Questionnaire (MODQ) and Visual Analog Scale (VAS) to determine their level of disability and pain severity, respectively. EMG activity of the rectus abdominis, external oblique, longissimus, and multifidus was recorded in both groups as they performed bilateral isometric shoulder and trunk contractions. RESULTS: In the LBP group, EMG activity of the rectus abdominis and external oblique muscles was significantly lower (P < 0.05). The LBP group had significantly more multifidus activity (P = 0.03) than the NLBP group. Among all the exercises, bilateral isometric shoulder extension contraction activated the rectus abdominis, right external oblique, and longissimus group of muscles significantly more (P < 0.05) in both groups. In both groups, bilateral isometric shoulder flexion contraction resulted in significantly higher multifidus muscle activation (P = 0.002). CONCLUSION: The activation of core stabilizing muscles was altered in athletes with LBP. When athletes are unable to contract and activate trunk muscles owing to pain, upper extremity exercises can be used to activate these muscles.

Comparison of the efficacy of manual treatment according to fascial distortion model versus joint mobilization in patients with shoulder impingement: A randomized clinical trial.

BACKGROUND: The Fascial Distortion Model (FDM) is a relatively new manual therapy approach in the field of musculoskeletal physical therapy, but to date no study has been conducted to compare its' effect in comparison with joint mobilization on patients with shoulder impingement syndrome. OBJECTIVE: The present study aims to compare the efficacy of the FDM versus joint mobilization in pain intensity, pain-free abduction range of motion and function of patients with shoulder impingement syndrome. DESIGN: single-blind, parallel-arm randomized controlled trial. METHODS: 26 patients diagnosed with shoulder impingement syndrome were equally randomized into 2 groups: manual treatment according to the FDM, and joint mobilization of the shoulder complex. All patients received 3 intervention sessions every other day. Pain intensity (by visual analogue scale), pain-free abduction range of motion (by goniometry) and function (by Persian version of shoulder pain and disability index) were measured before and after every session and at follow-up 2 weeks later. Patients' satisfaction with treatment was also measured (by a 4-point Likert scale) at follow-up. RESULTS: FDM therapy group showed statistically significant greater pain reduction (P = 0.014) and range of motion increment (P = 0.044) than joint mobilization group after intervention, while only range of motion maintained the difference at follow-up (P = 0.034). Function improvement was not statistically different after the intervention (P = 0.582) and at follow-up (P = 0.094). There was no difference in patients' satisfaction with treatment between groups (P > 0.05). CONCLUSION: The FDM is a safe and effective treatment approach with comparable results to joint mobilization in patients with shoulder impingement syndrome.

Unilateral seated shot-put test, muscle strength, and range of motion on recreational athletes with chronic shoulder pain: Cross-sectional study.

OBJECTIVE: To correlate the functional performance assessed by means of the Unilateral Seated Shot-Put Test (SSPT) with shoulder muscle strength, range of motion (ROM), and handgrip strength in recreational athletes with chronic shoulder pain. METHODS AND MATERIALS: The sample was composed of recreational athletes with nonspecific pain in the dominant shoulder ≥3 months, both sexes, aged between 18 and 45 years. We diagnosed shoulder pain by reporting pain intensity ≥3 points on the Numerical Rating Pain Scale and used the Shoulder Pain and Disability Index, Pain-Related Catastrophizing Thoughts Scale, and Baecke Questionnaire. Moreover, shoulder muscle strength, handgrip strength, ROM, and functional performance using the SSPT were evaluated. We used the Spearman correlation coefficient to investigate the correlation between the variables. RESULTS: Nineteen participants were included. Most of the sample consisted of adult women with adequate body mass and pain predominantly in the right shoulder. We observed higher correlation magnitudes of the SSPT with handgrip strength (rho = 0.818 to 0.833, p < 0.05). Correlations of the SPPT with shoulder musculature strength were of low to moderate magnitude (rho = 0.461 to 0.672, p < 0.05). The only significant correlation (p < 0.05) found was between the SSPT and ROM (horizontal adduction), however, with a weak magnitude (rho <0.50). CONCLUSION: SSPT correlates strongly with handgrip strength and moderately with shoulder muscle strength in recreational athletes with chronic shoulder pain.

Comparative effects of lymphatic drainage and soft tissue mobilization on pain threshold, shoulder mobility and quality of life in patients with axillary web syndrome after mastectomy.

PURPOSE: The purpose was to compare the effects of manual lymphatic drainage and soft tissue mobilization on pain threshold, shoulder mobility and quality of life in patients with axillary web syndrome. METHODS: This randomized clinical trial was conducted on 36 breast cancer patients with developed axillary web; participants were randomly divided into two groups. One group was treated with manual lymphatic drainage; the other group was treated with soft tissue mobilizations in addition to therapeutic exercises, i.e., stretching, strengthening and range of motion (ROM) exercises. The duration of treatment was four weeks (5 sessions/week), with therapeutic exercises as a common treatment protocol. Outcome measures were Breast-Cancer specific quality of life questionnaires, Disabilities of the Arm, Shoulder and Hand (DASH), Numeric Pain Rating Scale (NPRS), Patient Specific Functional Scale (PSFS), Dynamometer and Goniometer. All outcome measure readings were recorded at baseline and the end (4th week) of the treatment. RESULTS: The compliance of the variable distribution with normal distribution was verified using the Shaphiro-Wilk test. Parametric tests were applied, and both groups showed significant effects (p < 0.05) in pairwise comparison (paired t-test). The comparison group analysis (independent t-test) showed that there was no significant difference in pain, upper limb strength, range of motions and fatigue component of quality of life questionnaire parameters (p > 0.05). Two parameters (DASH, PSFS) and one component of the quality of life questionnaire (global health) showed a significant difference (p < 0.05). CONCLUSION: Manual lymphatic drainage showed more improvement in functional movements. It was concluded that both groups, manual lymphatic drainage and soft tissue mobilization groups were clinically equally effective. TRIAL REGISTRATION NUMBER: This trial is registered at ClinicalTrial.gov PRS under trial number NCT05463185 on date 18/07/2022.

Acupuncture is a feasible alternative to procedural sedation for shoulder reduction in the emergency department.

Treating shoulder dislocations is common in the emergency department and often requires procedural sedation. The use of acupuncture for treatment of chronic pain has been shown to be successful in various outpatient settings, and some EDs have recently incorporated acupuncture as an analgesia adjunct for chronic painful conditions to avoid opioid therapy. Limited data describe acupuncture to facilitate ED procedures. Here we present two cases of acute shoulder dislocation that were successfully treated with acupuncture as an alternative to parenteral pharmacologic procedural sedation. A 50 year old male sustained an anterior shoulder dislocation after an altercation, and a 59 year old female sustained an anterior dislocation after a fall. Instead of using conventional pharmacologic sedation and analgesia during shoulder reduction, both were treated with acupuncture in the ED. Reduction in both cases was rapid, safe, and avoided use of any parenteral medications, procedural sedation monitoring, or prolonged nurse observation. Using acupuncture as alternative to opioids for ED procedures deserves future study for orthopedic and other common ED procedures.

Efficacy of five-step shoulder manipulation for rotator cuff-related shoulder pain: protocol for a multicenter randomized controlled trial.

BACKGROUND: Rotator cuff-related shoulder pain (RCRSP) is the most common cause of shoulder disorders. In China, manipulation has been used extensively for the treatment of patients with RCRSP. However, high-quality clinical evidence to support the therapeutic effect of manipulation is still limited. METHODS: A multicenter, participant-, outcome assessor-, and data analyst-blinded, randomized, placebo-controlled trial will be conducted. A total of 280 participants with RCRSP will be recruited from three hospitals and randomly assigned to a five-step shoulder manipulation (FSM) group or a sham manipulation (SM) group. Each group will receive four weekly treatment sessions, with all participants performing exercises at home for 12 weeks. Assessments, namely the Constant-Murley score, visual analog scale, range of motion, and 36-Item Short Form Survey, will be made at baseline, 4, 12, 18, and 24 weeks. Adverse events during the study will also be recorded. DISCUSSION: This is a pragmatic clinical trial to evaluate the efficacy and safety of FSM in patients with RCRSP. The findings of this study will provide worthy clinical evidence for manual therapy for RCRSP. TRIAL REGISTRATION: China Registered Clinical Trial Registration Center ChiCTR2000037577.

Buccal acupuncture combined with ultrasound-guided dry needle-evoked inactivation of trigger points to treat cervical and shoulder girdle myofascial pain syndrome.

BACKGROUND: Myofascial pain syndrome (MPS) is a common disease with easy persistence and recurrence. In clinical practice, although many methods have been adopted to prevent and treat MPS, the control of MPS is still not satisfactory. OBJECTIVE: To compare the safety and effectiveness of buccal acupuncture, inactivation of trigger points (MTrPs), and their combination in the treatment of MPS. METHODS: Two hundred MPS patients in the pain clinic were randomly divided into four groups (n= 50) to receive oral drugs (Group A), oral drugs + buccal needle (Group B), oral drugs + MTrP inactivation (Group C), or oral drugs + buccal needle + MTrP inactivation (Group D). RESULTS: The visual analogue scale (VAS) and cervical range of motion (ROM) of Group D were significantly lower than those of the other three groups, and the pressure pain threshold (PPT) value of labelled MTrPs was significantly higher than those of the other three groups (P< 0.05). The excellent rate and total effective rate of Group D were significantly higher than those of the other three groups. Group C had the highest pain score and the lowest acceptance score. The results showed that buccal acupuncture combined with ultrasound-guided dry needle-evoked inactivation of MTrPs can significantly reduce the VAS score of MPS patients, improve the range of motion of the cervical spine, and improve patient satisfaction. CONCLUSIONS: This study provides a highly accepted and satisfactory treatment for MPS, which is worthy of clinical promotion.

Ruptured subclavian artery pseudoaneurysm following a shoulder massage on a background of clavicle non-union.

We present an unusual case of ruptured subclavian artery pseudoaneurysm following hydrotherapy and shoulder massage session on a background of clavicle non-union.Following a clavicle fracture 16 years ago, which was managed conservatively, a woman in her 30s presents over a decade later with a ruptured subclavian artery pseudoaneurysm.The original midshaft clavicle fracture was sustained 16 years ago. Conservative management was agreed, and she was discharged. Six years ago, she developed a small subclavian artery pseudoaneurysm which was kept under surveillance for 12 months with no active intervention required.Over the following years, she continued to have intermittent shoulder girdle discomfort and neuropathic symptoms. On this presentation, after a sports massage, she presented with rapid-onset supraclavicular and axillary swelling. This was diagnosed as a ruptured subclavian artery pseudoaneurysm and was treated with emergency radiological-guided stenting and subsequent internal fixation of the clavicle non-union.The patient then attended regular orthopaedic and vascular follow-up to ensure her clavicle fracture unites and the graft remains patent.We discuss the case presentation and management of this unusual injury.

Non-operative management of shoulder osteoarthritis: Current concepts.

Glenohumeral osteoarthritis (OA) is one of the most common causes of shoulder pain. Conservative treatment options include physical therapy, pharmacological therapy, and biological therapy. Patients with glenohumeral OA present shoulder pain and decreased shoulder range of motion (ROM). Abnormal scapular motion is also seen in patients as adaptation to the restricted glenohumeral motion. Physical therapy is performed to (1) decrease pain, (2) increase shoulder ROM, and (3) protect the glenohumeral joint. To decrease pain, it should be assessed whether the pain appears at rest or during shoulder motion. Physical therapy may be effective for motion pain rather than rest pain. To increase shoulder ROM, the soft tissues responsible for the ROM loss need to be identified and targeted for intervention. To protect the glenohumeral joint, rotator cuff strengthening exercises are recommended. Administration of pharmacological agents is the major part next to physical therapy in the conservative treatment. The main aim of pharmacological treatment is the reduction of pain and diminution of inflammation in the joint. To achieve this aim, non-steroidal anti-inflammatory drugs are recommended as first-line therapy. Additionally, the supplementation of oral vitamin C and vitamin D can help to slow down cartilage degeneration. Depending on the individual comorbidities and contraindications, sufficient medication with good pain reduction is thus possible for each patient. This interrupts the chronic inflammatory state in the joint and, in turn, enables pain-free physical therapy. Biologics such as platelet-rich plasma, bone marrow aspirate concentrate, and mesenchymal stem cells have gathered increased attention. Good clinical outcomes have been reported, but we need to be aware that these options are helpful in decreasing shoulder pain but neither stopping the progression nor improving OA. Further evidence of biologics needs to be obtained to determine their effectiveness. In athletes, a combined approach of activity modification and physical therapy can be effective. Oral medications can provide patients with transient pain relief. Intra-articular corticosteroid injection, which provides longer-term effects, must be used cautiously in athletes. There is mixed evidence for the efficacy of hyaluronic acid injections. There is still limited evidence regarding the use of biologics.

Microwave-induced hyperthermia in situ in the treatment of tumors of proximal humerus: long-term results with functionary sparing surgery.

BACKGROUND: The present study aimed to evaluate the indications, feasibility, clinical effectiveness and complications of the treatment with microwave in situ inactivation followed by curettage and bone grafting assisted with internal fixation, for the proximal humerus tumors. METHODS: The clinical data of 49 patients with primary or metastatic tumor of the proximal humerus who received intraoperative microwave inactivation in situ with curettage and bone grafting in our hospital from May 2008 to April 2021 were retrospectively analyzed. RESULTS: There were 25 males and 24 females, with an average age of 57.6 ± 19.9 years (range, 20-81). All patients were followed up for 7 to 146 months, with an average period of 69.2 ± 39.8 months. Up to the last follow-up, 14 patients died. The 5-year overall survival was 67.3%, and 5-year tumor-specific survival was 71.4%. The 5-year tumor-specific survival rates were 100% for aggressive benign tumors or low potential malignancy tumors, 70.1% for primary malignancies, and 36.9% for metastatic tumors. The average preoperative MSTS, constant-Murley and VAS scores were 16.81 ± 3.85, 62.71 ± 12.56 and 6.75 ± 2.47, which were all significantly improved at 6 weeks after operation and at the final follow-up (P < 0.05). CONCLUSIONS: Microwave inactivation in situ and curettage and bone grafting are a feasible treatment for tumors of proximal humeral, especially for malignant tumors and metastases, without the necessity of the replacement of the shoulder, with little trauma and good upper limb function, and with low local recurrence and distant metastasis.

Ischemic pressure vs. post-isometric relaxation for treatment of rhomboid latent myofascial trigger point: a systemic review.

OBJECTIVE: This systematic review was carried out to review ischemic pressure and post-isometric relaxation for treatment of rhomboid latent myofascial trigger point. MATERIALS AND METHODS: This systematic review was organized using PRISMA and Cochrane standards. This meta-analysis compares ischemic pressure to post-isometric relaxation for rhomboid latent myofascial trigger point. Search terms included: myofascial pain, trigger point, ischemia pressure, post-isometric relaxation, and electric stimulation. We first searched MEDLINE (including ePub, Ahead of Print, InProgress, and Other Non-Indexed Citations) and then EMBASE and the Cochrane CENTRAL Register of Controlled Trials. Searches were conducted from the databases' inception through August 2022. RESULT: The RCT review followed PRISMA criteria. PubMed, Embase, PSYCHInfo, and the Cochrane Library were searched from their origin without language constraints to locate all RCTs linked to ischemic pressure vs. post-isometric relaxation for therapy of rhomboid latent myofascial trigger point. 463 duplicates were removed. 140 of 174 citations were removed. Seven high-quality full-text papers out of 34 were included. CONCLUSIONS: Conservative and noninvasive treatments can only raise pain tolerance. Compared to standard treatment, ischemia pressure and post-isometric relaxation reduced shoulder and neck pain and PPT discomfort. This study suggests that ischemia compression may be more effective than post-isometric relaxation for treating rhomboid latent myofascial trigger points (MTP). Future progress in the field will depend on multi-subject RCTs.
