Exploring the feasibility and acceptance of an optimised physiotherapy approach for lateral elbow tendinopathy: a qualitative investigation within the OPTimisE trial.

OBJECTIVES: To explore the acceptability of an optimised physiotherapy (OPTimisE) intervention for people with lateral elbow tendinopathy (LET) and feasibility of comparing it to usual care in a randomised controlled trial. DESIGN: Semistructured interviews, analysed using thematic analysis and mapped onto the COM-B model of behaviour change. SETTING: Conducted as part of the OPTimisE Pilot & Feasibility randomised controlled trial within physiotherapy departments in the United Kingdom National Health Service. PARTICIPANTS: 17 patients with LET (purposively sampled to provide representativeness based on age, sex, ethnicity, deprivation index and treatment allocation) and all 8 physiotherapists involved as treating clinicians or site principal investigators. RESULTS: Four themes were identified. First, participants reported the OPTimisE intervention as acceptable. Second, differences between the OPTimisE intervention and usual care were identified, including the use of an orthosis, holistic advice/education including modifiable risk factors, forearm stretches, general upper body strengthening and a more prescriptive exercise-dosing regimen. Third, participants provided feedback related to the trial resources, which were viewed positively, but identified language translation as a need. Fourth, feedback related to trial processes identified the need for changes to outcome collection and reduction of administrative burden. From the perspective of adopting the OPTimisE intervention, we found evidence that participants were able to change their behaviour. Considering the findings through the lens of the COM-B model, the intervention is likely to be deliverable in practice and the trial can be delivered at scale with some additional support for physiotherapists. CONCLUSIONS: Overall, the OPTimisE intervention was found to be different to usual care and acceptable to patients and physiotherapists. The study highlighted the need to refine trial processes and resources prior to a full-scale trial, to reduce administrative burden, increase support for physiotherapists, improve return rate of outcome questionnaires and provide language translation.

Physical therapy interventions used to treat individuals with biceps tendinopathy: a scoping review.

BACKGROUND: Shoulder pain related to pathology of the long head of the biceps tendon (LHBT) can be debilitating. Chronic LHBT tendinopathy is a common condition that is difficult to treat. Little consensus exists regarding the optimal approach to treating individuals with LHBT tendinopathy. OBJECTIVE: To systematically scope the literature to identify and present the available information regarding physical therapist interventions used for the management of individuals with LHBT tendinopathy including types of interventions used or recommended. METHODS: A scoping review of physical therapist interventions used to treat LHBT was conducted of the CINAHL, Embase, Medline, and SportDiscus databases. Full text records reporting physical therapist-based interventions in individuals with proximal LHBT pathology were included. Articles not written in English were excluded. RESULTS: Of the 4059 records identified, 14 articles met the inclusion criteria. Interventions used to treat LHBT tendinopathy identified in quantitative studies included: extracorporeal shock wave therapy, polarized light, ultrasound, low-level laser, iontophoresis, general exercise, eccentric training, stretching, dry needling, and joint mobilization. Interventions described in literature reviews, clinical commentaries, and a Delphi study included: therapeutic modalities, manual therapy, exercise, dry needling, and patient education. CONCLUSION: This scoping review reported interventions primarily based on therapeutic modalities in quantitative studies while literature reviews, clinical commentaries, and a Delphi study described the addition of manual therapy, patient education, exercise, and dry needling. Overall, there is a dearth of evidence detailing the conservative management of LHBT tendinopathy.

Focused ultrasound as an alternative to dry needling for the treatment of tendinopathies: A murine model.

Tendinopathies account for 30% of 102 million annual musculoskeletal injuries occurring annually in the United States. Current treatments, like dry needling, induce microdamage to promote healing but produce mixed success rates. Previously, we showed focused ultrasound can noninvasively create microdamage while preserving mechanical properties in ex vivo murine tendons. This present study compared growth factor, histological, and mechanical effects after focused ultrasound or dry needling treatments in an in vivo murine tendon injury model. Partial Achilles tenotomy was performed in 26 rats. One-week postsurgery, tendons were treated with focused ultrasound (1.5 MHz, 1-ms pulses at 10 Hz for 106 s, p+ = 49 MPa, p- = 19 MPa) or dry needling (30 G needle, 5 fenestrations over 20 s) and survived for 1 additional week. Blood was collected immediately before and after treatment and before euthanasia; plasma was assayed for growth factors. Treated tendons and contralateral controls were harvested for histology or mechanical testing. No differences were found between treatments in release of insulin growth factor 1 and transforming growth factor beta; vascular endothelial growth factor A concentrations were too low for detection. Histologically, focused ultrasound and dry needling tendons displayed localized fibroblast infiltration without collagen proliferation with no detectable differences between treatments. Mechanically, stiffness and percent relaxation of dry needling tendons were lower than controls (p = 0.0041, p = 0.0441, respectively), whereas stiffness and percent relaxation of focused ultrasound tendons were not different from controls. These results suggest focused ultrasound should be studied further to determine how this modality can be leveraged as a therapy for tendinopathies.

Exercise therapy for tendinopathy: a mixed-methods evidence synthesis exploring feasibility, acceptability and effectiveness.

Background: Tendinopathy is a common, painful and functionally limiting condition, primarily managed conservatively using exercise therapy. Review questions: (i) What exercise interventions have been reported in the literature for which tendinopathies? (ii) What outcomes have been reported in studies investigating exercise interventions for tendinopathy? (iii) Which exercise interventions are most effective across all tendinopathies? (iv) Does type/location of tendinopathy or other specific covariates affect which are the most effective exercise therapies? (v) How feasible and acceptable are exercise interventions for tendinopathies? Methods: A scoping review mapped exercise interventions for tendinopathies and outcomes reported to date (questions i and ii). Thereafter, two contingent systematic review workstreams were conducted. The first investigated a large number of studies and was split into three efficacy reviews that quantified and compared efficacy across different interventions (question iii), and investigated the influence of a range of potential moderators (question iv). The second was a convergent segregated mixed-method review (question v). Searches for studies published from 1998 were conducted in library databases (n = 9), trial registries (n = 6), grey literature databases (n = 5) and Google Scholar. Scoping review searches were completed on 28 April 2020 with efficacy and mixed-method search updates conducted on 19 January 2021 and 29 March 2021. Results: Scoping review - 555 included studies identified a range of exercise interventions and outcomes across a range of tendinopathies, most commonly Achilles, patellar, lateral elbow and rotator cuff-related shoulder pain. Strengthening exercise was most common, with flexibility exercise used primarily in the upper limb. Disability was the most common outcome measured in Achilles, patellar and rotator cuff-related shoulder pain; physical function capacity was most common in lateral elbow tendinopathy. Efficacy reviews - 204 studies provided evidence that exercise therapy is safe and beneficial, and that patients are generally satisfied with treatment outcome and perceive the improvement to be substantial. In the context of generally low and very low-quality evidence, results identified that: (1) the shoulder may benefit more from flexibility (effect sizeResistance:Flexibility = 0.18 [95% CrI 0.07 to 0.29]) and proprioception (effect sizeResistance:Proprioception = 0.16 [95% CrI -1.8 to 0.32]); (2) when performing strengthening exercise it may be most beneficial to combine concentric and eccentric modes (effect sizeEccentricOnly:Concentric+Eccentric = 0.48 [95% CrI -0.13 to 1.1]; and (3) exercise may be most beneficial when combined with another conservative modality (e.g. injection or electro-therapy increasing effect size by ≈0.1 to 0.3). Mixed-method review - 94 studies (11 qualitative) provided evidence that exercise interventions for tendinopathy can largely be considered feasible and acceptable, and that several important factors should be considered when prescribing exercise for tendinopathy, including an awareness of potential barriers to and facilitators of engaging with exercise, patients' and providers' prior experience and beliefs, and the importance of patient education, self-management and the patient-healthcare professional relationship. Limitations: Despite a large body of literature on exercise for tendinopathy, there are methodological and reporting limitations that influenced the recommendations that could be made. Conclusion: The findings provide some support for the use of exercise combined with another conservative modality; flexibility and proprioception exercise for the shoulder; and a combination of eccentric and concentric strengthening exercise across tendinopathies. However, the findings must be interpreted within the context of the quality of the available evidence. Future work: There is an urgent need for high-quality efficacy, effectiveness, cost-effectiveness and qualitative research that is adequately reported, using common terminology, definitions and outcomes.

Tendons are cords of strong, flexible tissue that attach muscles to bones, allowing joints to move. Tendinopathy is a common condition that can affect any tendon in the body, causing pain and limiting function. Exercise is often used to treat tendinopathy. We examined over 500 research papers on exercise for tendinopathy. The most common tendons to be studied were the calf (Achilles), knee (patellar), elbow and shoulder. Strengthening exercise was studied most often, especially in lower-limb tendinopathy. Other types of exercise such as stretching, balance and aerobic activity were less common, but were used to some extent in the upper and lower limbs. We found that exercise therapy is safe and beneficial for the tendinopathies that have been studied to date. Exercise may be most beneficial when combined with another intervention such as injection or electro-therapy. Strengthening exercise may be most beneficial for lower-limb tendinopathies. However, more research is needed on the type of strengthening and the dosage, such as how many exercises and how much resistance to use. Shoulder tendinopathies may benefit from exercise that targets joint flexibility and position more than strengthening. We also found that people who receive exercise therapy for tendinopathy are generally satisfied with the effect it has on their symptoms. Finally, we found that an individualised, person-centred approach to delivering exercise therapy is valued by people with tendinopathy. They also believe that the patient-healthcare provider relationship is important for promoting the confidence and motivation people need to continue with exercise programmes, especially when they complete them independently. Although we examined a lot of papers, many of the studies were low quality. This means there is still a need for high-quality studies to tell us how effective specific types of exercise are for specific tendinopathies. There is also a need for more studies on patients' and professionals' experiences of receiving or providing exercise for tendinopathy.

Acupuncture combined with Tuina in the treatment of cervical longus tendinitis: A case report.

INTRODUCTION: Cervical longus tendonitis is a type of disease with neck pain as the main clinical manifestation. Because the front of the cervical longus muscle is adjacent to the esophagus and pharynx, this disease is often accompanied by pharyngeal pain and pain when swallowing. Clinical and imaging doctors often have an incomplete understanding of it, and this disease is often confused with other diseases that cause neck pain. PATIENT CONCERNS: A 33-year-old Chinese woman was the patient. Suffering from severe neck pain and significantly limited activity, accompanied by left shoulder pain, occasionally dizziness, headache and other symptoms, the pain is significantly aggravated when doing swallowing action. DIAGNOSIS: Tendonitis of the long neck muscle. INTERVENTIONS: Given the patient's condition, we used acupuncture combined with massage therapy as a symptomatic treatment. OUTCOMES: After 10 days of treatment, the symptoms were better than before, and no pain was seen in the swallowing movements such as drinking water (Fig. 2C and D). LESSONS: Because the clinical reports of diseases are rare, the treatment methods are limited, and acupuncture combined with massage is an effective method for the treatment of tendonitis of the cervical long muscle, to dredge the meridians, promoting blood circulation, removing blood stasis and relieving pain.

Effects of platelet-rich plasma and prolotherapy on supraspinatus tendinopathy: a double blind randomized clinical trial.

BACKGROUND: Supraspinatus tendinopathy is a significant cause of pain and function loss. It has been suggested that platelet-rich plasma (PRP) and prolotherapy are effective treatments for this condition. This study was done to assess and compare the effects of PRP and prolotherapy on shoulder function and pain. The secondary aim was to evaluate the effect of the treatment on shoulder range of motion, supraspinatus tendon thickness, patient satisfaction, and adverse effects. METHODS: This was a randomized, double-blind clinical trial. The study included 64 patients over the age of 18 who had supraspinatus tendinopathy and had not responded to at least three months of conventional treatment. Patients were assigned to either receive 2 mL of PRP (N.=32) or prolotherapy (N.=32). The Shoulder Pain and Disability Index (SPADI) and the Numerical Rating Scale (NRS) were the primary outcomes. Secondary outcomes included shoulder range of motion (ROM), supraspinatus tendon thickness, and adverse effects, which were measured at baseline, 3, 6, and 6 months after injection. At six months, patient satisfaction was assessed. RESULTS: Repeated measures ANOVA showed there was a statistically significant effect of time on total SPADI scores (F [2.75, 151.11], = 2.85, P=0.040) and the NRS (F [2.69, 147.86], = 4.32, P=0.008) within each group. There were no other significant changes over time or between groups. Significantly more patients in the PRP group experienced increased pain lasting less than two weeks after injection (χ2=11.94, P=0.030). CONCLUSIONS: PRP and prolotherapy resulted in improved shoulder function and pain for patients with chronic supraspinatus tendinopathy who did not response to conventional treatment.

Nutritional Supplements in the Clinical Management of Tendinopathy: A Scoping Review.

INTRODUCTION: Tendinopathy has a high prevalence and incidence in the general population and among athletes, with a lack of consensus among medical practitioners on optimal management strategies. The objective of this scoping review was to evaluate current research on the use of nutritional supplements for treating tendinopathies, including what supplements have been used and what outcomes, outcome measures, and intervention parameters have been reported. METHODS: Databases searched included Embase, SPORTDiscus, the Cochrane Library, MEDLINE, CINAHL, and AMED. This scoping review considered primary studies investigating nutritional supplements for tendinopathies and was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Reviews. RESULTS: A total of 1527 articles were identified with 16 included in the review. Studies investigated a range of nutritional supplements in the clinical management of various tendinopathies, including several commercially available proprietary blends of several ingredients. TendoActive (mucopolysaccharides, type I collagen, and vitamin C) was used in 2 studies, TENDISULFUR (methylsulfonylmethane, hydrolyzed collagen, L-arginine, L-lysine, vitamin C, bromelain, chondroitin, glucosamine, Boswellia, and myrrh) was used in 3 studies, and Tenosan (arginine-L-alpha ketoglutarate, hydrolyzed collagen type I, methylsulfonylmethane, vitamin C, bromelain, and vinitrox) was used in 2 studies. Collagen peptides were used in 2 studies, with omega-3 fatty acids, combined fatty acids and antioxidants, turmeric rhizome combined with Boswellia, ß-hydroxy ß-methylbutyric, vitamin C in isolation and combined with gelatin, and creatine investigated in one study each. CONCLUSION: Despite a paucity of studies to date, findings from this review suggest that several nutritional compounds may be beneficial in the clinical management of tendinopathies, by exerting anti-inflammatory effects and improving tendon healing. Nutritional supplements may have potential as an adjunctive method to standard treatment methods such as exercise, where their pain-relieving, anti-inflammatory, and structural tendon effects may augment the positive functional outcomes gained from progressive exercise rehabilitation.

Effectiveness of ultrasound guided dry needling in management of jumper's knee: a randomized controlled trial.

Jumper's knee is highly prevalent condition in athletes. Very limited evidence is available on clinical effects of tendon dry needling. Therefore, the objective of this study is to compare the effects of ultrasound-guided dry needling (UG-DN) combined with conventional physical therapy and conventional physical therapy alone in patients with jumper's knee. A total of 96 patients with pre-diagnosed jumper's knee were randomly assigned to experimental group (UG-DN + CPT) and conventional group (CPT alone) with 48 participants each. Pain intensity and functional disability were recorded using visual Analogue Scale (VAS), Victorian Institute of Sports Assessment-Patellar Tendinopathy (VISA-P) questionnaire, Lysholm Scale, Knee Injury and Osteoarthritis Outcome Score (KOOS) respectively at baseline, at 1st, 2nd, and 4th week. Whereas ultrasonographic features of patellar tendon were measured through musculoskeletal ultrasound (MSKUS) at baseline and 4th week. Total 8 sessions of treatment were provided. Mann Whitney U test and Friedman test were used to compute between and within group differences respectively. P value was significant at 0.05. Results showed that patients in both groups had improvement in signs of jumper's knee but the improvement in UG-DN + CPT group was more significant (p ≤ 0.05). Significant difference was seen after 4 weeks of intervention in UG-DN + CPT group in VAS (Median ± I.Q.R = 3 ± 1, p = 0.000), VISA-P (Median ± I.Q.R = 83.5 ± 7, p = 0.000), KOOS (Median ± I.Q.R = 83.5 ± 8, p = 0.000), , Lysholm (Median ± I.Q.R = 84 ± 5, p = 0.000) than CPT group VAS (Median ± I.Q.R = 1.5 ± 1, p = 0.000), VISA-P (Median ± I.Q.R = 92 ± 2, p = 0.000), KOOS (Median ± I.Q.R = 92 ± 3, p = 0.000), Lysholm (Median ± I.Q.R = 92 ± 4, p = 0.000) and ultrasonographic features of jumper's knee were more significant in experimental group(p-value ≤ 0.05). The Ultrasound guided dry needling with conventional physical therapy of patellar tendon had been found an effective treatment for jumper's knee and helps in reducing pain intensity, improving function and ultrasonographic features in patients with jumper's knee. UG-DN + CPT group showed more significant results as compared to CPT.Trial registration: (IRCT20210409050913N1). Dated: 17.04.2021.

Changes After a Conventional vs. an Alternative Therapy Program on Physical, Psychological, and Injury-Related Parameters in Male Youth Soccer Players With Patellar Tendinopathy During Return to Competition.

ABSTRACT: Niering, M and Muehlbauer, T. Changes after a conventional vs. an alternative therapy program on physical, psychological and injury-related parameters in male youth soccer players with patellar tendinopathy during return to competition. J Strength Cond Res 37(9): 1834-1843, 2023-Changes after a conventional (CON) vs. alternative (ALT) therapy program on physical, psychological, and injury-related or pain-related parameters in soccer players with patellar tendinopathy (PT) during return to competition were examined. Thirty-four male youth soccer players (15-16 years) with PT were randomly assigned to a CON ( n = 18) or ALT ( n = 16) program. The ALT program consisted of 60 minutes of balance training, eccentric and isometric exercises, static stretching, and a dual-task progression. The CON program consisted of 30 minutes of eccentric and isometric exercises and static stretching. Both programs were conducted until painlessness was reported during full training load. Assessments of muscle power (drop jump, jump and reach), change of direction speed (CODS) (acyclic sprint), speed (tapping, 30-m linear sprint), endurance (Yo-Yo intermittent recovery test level-1), the Achievement Motives Scale Sport, and injury-related or pain-related correlates were performed immediately, 6 weeks, 16 weeks, and 20 weeks after the respective therapy program. Players in the ALT group required a shorter program duration (ALT: 47.1 ± 15.6 days, CON: 58.2 ± 24.6 days) and achieved the same (muscle power, speed, endurance) or greater (CODS) improvements in physical performances, the same enhancements in psychological measures (achievement motives), and better values for injury-related or pain-related correlates (injury incidence, pain-related training interruptions). Results indicate that both programs effectively improve relevant outcome parameters in players with PT. The ALT therapy is more time efficient than the CON therapy. Therapists should consider this multimodal training program for effective treatment of athletes to shorten their return to competition time and minimize the risk of secondary injuries.

Dry needling in the management of tendinopathy: A systematic review of randomized control trials.

INTRODUCTION: The objective of the study is to evaluate the best available evidence on the effectiveness of DN in the management of tendinopathy. METHODS: Seven randomized control trials were selected following an electronic search in PubMed, Web of Science, Scopus, and SPORTDiscus databases. To be included in the current systematic review, the study had to be an RCT conducted on human participants, which investigated the effect of the DN technique on the management of tendinopathies. Only studies in the English language published in peer-reviewed journals between 1999 and 2020 were included. The methodological quality of the studies was assessed using the PEDro scale. RESULTS: The PEDro score of the studies ranged from 5 to 9 with a mean score of 6.7 ± 1.2 (mean ± SD). A total of 357 participants were enrolled in the seven included studies, which were on greater trochanteric pain syndrome, lateral epicondylitis, supraspinatus tendinopathy and Achilles tendinopathy. DN was compared with various interventions, including platelet-rich plasma injection, autologous blood injection and non-steroidal anti-inflammatory medication. All the selected studies reported a significant positive effect of DN on pain intensity and other outcome measures, such as patient-specific functional score, disability index, range of motion and health-related quality of life. CONCLUSION: The results indicate that DN appears to be as effective as other treatment methods at relieving pain and other symptoms of tendinopathy immediately after treatment and up to 6 months. DN can be considered among the many options available for the management of tendinopathy.

Conservative management of distal bicipital tendinopathy with lateral antebrachial nerve entrapment: A case report.

INTRODUCTION: Kettlebell snatches are an efficient and effective exercise. If the kettlebell being utilized is too heavy or too many repetitions are executed, this can lead to an overuse injury such as a tendinopathy. Multiple orthopedic tests exist to evaluate for a distal biceps tendon rupture. At present, there are no publications utilizing shockwave and active rehabilitation to treat distal bicipital tendinopathy with Lateral Antebrachial Cutaneous Nerve (LABCN) entrapment. Currently, no published manuscripts are reporting distal bicipital tendinopathy with LABCN nerve entrapment being treated successfully with shockwave and active rehabilitation over the course of 5 weeks. METHODS: The objective of this case report is to examine the conservative management of a 37-year-old male with a diagnosis of distal bicipital tendinopathy and LABCN entrapment. The patient presents with discomfort originated weeks prior after an intense block of kettlebell training. The patient was diagnosed with brachioradialis tendinopathy due to the specifics of his injury. Following the initial evaluation, the patient was unable to supinate the forearm past 45° actively, yet he can passively achieve 90°, although this is done with minor discomfort. DISCUSSION: The patient's rehab began with the execution of wrist, elbow, and shoulder controlled articular rotation (CARS). The concept of CARs is to train the joint and soft tissues to respond to full range activity. A progressive approach utilizing isometric to eccentric exercise with extracorporeal shockwave was used. The authors studied forty-eight patients with chronic distal biceps tendinopathy. After five shockwave therapy treatments over three months, there was a significant decrease in symptomology without complications (Furia et al., 2017). CONCLUSION: This case report demonstrates that active rehabilitation and shockwave therapy effectively resolved the patient's symptoms with no adverse reactions. Additionally, the case report can be a suggested management protocol for successful conservative management for patients with suspected distal bicipital tendinopathy with LABCN entrapment going forward.

Emerging Treatment Options for Chronic Tendinopathy of the Foot: A Clinical Vignette.

ABSTRACT: The patient is a 65-year-old female recreational skier and avid walker who presented with a several-month history of right ankle and foot pain. The patient's pain began without inciting event and was described as a constant aching pain aggravated by downhill walking and alleviated with rest. She was diagnosed with right distal tibialis anterior tendinopathy with partial thickness tear noted on magnetic resonance imaging and musculoskeletal ultrasound. Given symptoms recalcitrant to conservative measures, the patient opted to pursue an ultrasound-guided prolotherapy injection and a course of physical therapy; unfortunately, she did not have any improvement in symptoms. The patient subsequently underwent ultrasound-guided percutaneous ultrasonic tenotomy and debridement of the distal tibialis anterior tendon, followed by a postprocedure rehabilitation protocol of physical therapy with transition to home exercise program with complete resolution of her pain. Prolotherapy, and percutaneous ultrasonic tenotomy and debridement are two treatment modalities that show promise in the treatment of painful, chronic tendinopathy.

Prolotherapy: A Narrative Review of Mechanisms, Techniques, and Protocols, and Evidence for Common Musculoskeletal Conditions.

Prolotherapy is a nonsurgical regenerative technique that allows small amounts of irritant solution to be injected into the site of painful tendon and ligament insertions to promote the growth of healthy cells and tissues. The goal of prolotherapy is to stimulate growth factors that may strengthen attachments and reduce pain. Prolotherapy injection technique is centered around a focused physical examination and strong anatomic knowledge for maximized results. Prolotherapy is beneficial in a variety of different musculoskeletal conditions, including, but not limited to, lateral epicondylosis, rotator cuff tendinopathy, plantar fasciitis, Achilles tendinopathy, osteoarthritis, low back pain, sacroiliac joint pain, and TMJ laxity.

Ultrasound-guided injection of platelet-rich plasma for tendinopathies: a systematic review and meta-analysis.

BACKGROUND: In this systematic review and meta-analysis, we evaluated ultrasound (US)-guided injections of platelet-rich plasma (PRP) as conservative treatment of tendinopathies. MATERIALS AND METHODS: We searched MEDLINE, EMBASE, SCOPUS, OVID, and the Cochrane Library to identify randomized controlled trials (RCT) on the use of US-guided PRP for tendinopathies. RESULTS: We found 33 RCT (2,025 subjects) that met our inclusion criteria: 8 in lateral epicondylitis, 5 in plantar fasciitis, 5 in Achilles tendinopathy, 7 in rotator cuff tendinopathy, 3 in patellar tendinopathy and 5 in carpal tunnel syndrome. PRP, given as a single injection (20 trials) or multiple injections (13 trials), was compared to US-guided injection of steroids, saline, autologous whole blood, local anesthetic, dry needling, prolotherapy, bone marrow mesenchymal stem cells, or with non-injective interventions. The outcomes more commonly reported included pain and functional measures, subgrouped as in the short-term (<3 months from the intervention), medium-term (3 to 6 months) or long-term (≥12 months). No clear between-group differences in these outcomes were observed in patients with lateral epicondylitis, plantar fasciitis, or Achilles, rotator cuff or patellar tendinopathy. In patients with carpal tunnel syndrome, visual analog scale scores for pain at 3 and 6 months and Boston Carpal Tunnel Questionnaire severity scores at 1, 3 and 6 months were significantly lower in PRP recipients than in controls. The certainty of evidence of all these comparisons was graded as low or very low due to risk of bias, imprecision and/or inconsistency. Pain at the injection site was more common among PRP recipients than among controls receiving other US-guided injections. DISCUSSION: In patients with tendinopathies, a trend towards pain reduction and functional improvement from baseline was observed after US-guided PRP injection, but in the majority of the comparisons, the effect size was comparable to that observed in control groups.

The impact of nutrition on tendon health and tendinopathy: a systematic review.

Background: Tendinopathy is a painful condition that is prevalent in athletes as well as the general human population, and whose management is challenging. Objective: This systematic review aimed to evaluate the impact of nutrition on the prevention and treatment of tendinopathy. Methods: Searches were conducted in PubMed, EMBASE, Web of Science, and SPORTDiscus without restriction to year of publication. Studies examining the impact of exposure to nutrient intake in an adult human population on 1) prevalence/incidence of tendinopathy, 2) clinical outcomes of tendinopathy, 3) structural changes in the tendon by imaging modalities. Experimental and observational study designs written in English, Dutch, or German were eligible. Results: Nineteen studies met the inclusion criteria. The effects of the habitual diet were investigated in one study. Four studies examined the effects of exposure to alcohol. Alcohol consumption can be a potential risk factor associated with Achilles tendinopathy and rotator cuff tears, although findings were inconsistent. The use of dietary supplements was examined in fourteen studies. Among these, collagen-derived peptides were most often part of the supplements evaluated. Combining training and dietary supplements seems to induce better clinical and functional outcomes in tendinopathy. Conclusion: This review demonstrates the paucity of high-quality studies and a wide variety among studies regarding nutrients, tendon location, study population, and reported outcome measures. Individual studies showed promising clinical implications for the use of dietary supplements, particularly those containing collagen-derived peptides. However, giving any definitive dietary recommendations on the prevention and treatment of tendinopathy remains elusive.

Therapeutic Ultrasound and Shockwave Therapy for Tendinopathy: A Narrative Review.

ABSTRACT: Tendon injury is prevalent and costly in the United States, comprising 45% of the 66 million musculoskeletal injuries and costing $114 billion annually. Surgical and therapeutic methods, such as arthroscopic surgery, dry needling, and physical therapy, produce mixed success in reintroducing a healing response in tendinopathy due in part to inconsistent dosing and monitoring. Ultrasound is one therapeutic modality that has been shown to noninvasively induce bioeffects in tendon that may help promote healing. However, results from this modality have also been mixed. This review compares the current state of the field in therapeutic ultrasound and shockwave therapy, including low-intensity therapeutic ultrasound, extracorporeal shockwave therapy, and radial shockwave therapy, and evaluates the efficacy in treating tendinopathies with ultrasound. We found that the mixed successes may be attributed to the wide variety of achievable parameters within each broader treatment type and the lack of standardization in measurements and reporting. Despite mixed outcomes, all three therapies show potential as an alternative therapy with lower-risk adverse effects than more invasive methods like surgery. There is currently insufficient evidence to conclude which ultrasound modality or settings are most effective. More research is needed to understand the healing effects of these different therapeutic ultrasound and shockwave modalities.

A comparative study of treatment interventions for patellar tendinopathy: a secondary cost-effectiveness analysis.

OBJECTIVE: To compare the cost-effectiveness of three patellar tendinopathy treatments. DESIGN: Secondary (cost-effectiveness) analysis of a blinded, randomised controlled trial, with follow-up at 10 and 22 weeks. SETTINGS: Recruitment was performed in sport clubs. The diagnosis and the intervention were carried out at San Jorge University. PARTICIPANTS: The participants were adults between 18 and 45 years (n = 48) with patellar tendinopathy. INTERVENTIONS: Participants received percutaneous needle electrolysis, dry needling or sham needling, all of which were combined with eccentric exercise. MAIN OUTCOME MEASURES: Costs, quality-adjusted life years and incremental cost-effectiveness ratio were calculated for each group. RESULTS: The total cost per session was similar in the three groups: €9.46 for the percutaneous needle electrolysis group; €9.44 for the dry needling group; and €8.96 for the sham group. The percutaneous needle electrolysis group presented better cost-effectiveness in terms of quality-adjusted life years and 96% and 93% probability of being cost-effective compared to the sham and dry needling groups, respectively. CONCLUSION: Our study shows that percutaneous needle electrolysis has a greater probability of being cost-effective than sham or dry needling treatment.

The Effectiveness of Dry Needling Combined With Therapeutic Exercises in Treating Tendinopathy Conditions: A Systematic Review.

CONTEXT: Approximately 70,000 Americans miss work annually due to tendinopathies causing pain, disability, and lower quality of life. Various conservative treatments have been demonstrated to improve outcomes in these conditions. Dry needling (DN) and therapeutic exercise are 2 such interventions that have been proposed to be a positive intervention for addressing tendinopathy. OBJECTIVE: To summarize the best available evidence on the use of DN and exercise combined to treat tendinopathy. EVIDENCE ACQUISITION: PubMed, EBSCOHost, and Web of Science were systematically searched from inception to March 2021. Articles were assessed to determine eligibility and evaluated for methodological quality using the PEDro scale. The PRISMA guidelines were used for this review. Inclusion criteria consisted of use of DN in combination with therapeutic exercise, human participants, and active tendinopathy pathology. EVIDENCE SYNTHESIS: Seven studies met the inclusion and exclusion criteria, which averaged 6/11 on the PEDro scale. The level of agreement of evaluators was 94%. Current evidence supports the use of DN combined with therapeutic exercises, especially those including eccentric exercises, can improve pain and function for various tendinopathies. However, limited evidence exists regarding specific therapeutic interventions to be combined with DN. CONCLUSION: There is moderate, level B evidence to suggest the use of DN techniques targeted at the tendon and combined with eccentric therapeutic exercise to improve pain and functional outcomes for tendinopathies.

The Achilles Tendon: Imaging Diagnoses and Image-Guided Interventions-AJR Expert Panel Narrative Review.

The Achilles tendon is commonly affected by both chronic repetitive overuse and traumatic injuries. Achilles tendon injuries can potentially affect any individual but have a particularly high incidence in professional athletes. Appropriate imaging evaluation and diagnosis are paramount to guiding appropriate management. In this AJR Expert Panel Narrative Review, we discuss the role of various imaging modalities (particularly ultrasound and MRI) in the assessment of Achilles tendon pathology, focusing on the modalities' relative advantages and technical considerations. We describe the most common diagnoses affecting the Achilles tendon and adjacent structures, highlighting key imaging findings and providing representative examples. Various image-guided interventions that may be used in the management of Achilles tendon pathology are also reviewed, including high-volume injection, tendon fenestration, prolotherapy, and corticosteroid injection. The limited evidence supporting such interventions are summarized, noting an overall paucity of large-scale studies showing benefit. Finally, a series of consensus statements by the panel on imaging and image-guided intervention for Achilles tendon pathology are provided.
