Purpose
The general consensus that tendinopathy, at least in the chronic stage, is mainly a degenerative condition and inflammation plays a minor role has led to a shift from treatments that target ...inflammation towards treatment options that promote regeneration. One of these treatments is extracorporeal shockwave therapy (ESWT), a physical therapy modality that uses pressure waves to treat tendinopathy. This review was undertaken to give an overview of the literature concerning this treatment, and special attention is given to the differences between focused and radial ESWT.
Methods
A narrative description of wave characteristics, generation methods and in vitro effects of ESWT is given. The literature on ESWT as a treatment for one common tendinopathy, patellar tendinopathy, was systematically reviewed.
Results
Waves that are generated for focused and radial ESWT have very different physical characteristics. It is unclear how these characteristics are related to clinical effectiveness. Studies into the biological effects of ESWT have mainly used focused shockwave therapy, showing a number of effects of shockwaves on biological tissue. The systematic review of studies into the clinical effects of ESWT for patellar tendinopathy showed conflicting evidence for its effectiveness.
Conclusion
Physical characteristics of focused and radial waves differ substantially, but effect on clinical effectiveness is unclear. Whereas in vitro studies often show the effects of ESWT on tendon tissue, results of clinical studies are inconsistent. Based on the review of the literature, suggestions are given for the use of ESWT in clinical practice regarding timing and treatment parameters.
Level of evidence
IV.
Background: Patellar tendinopathy is a common overuse injury among jumping athletes. No evidence-based treatment guidelines exist. Extracorporeal shockwave therapy (ESWT) appears to be a promising ...treatment but its effectiveness has not been studied in athletes with patellar tendinopathy who have symptoms for 3 to 12 months and are still playing.
Purpose: The TOPGAME study was created to determine the effectiveness of ESWT on pain, symptoms, and function in athletes with early symptomatic patellar tendinopathy who are still in training and competition.
Study Design: Randomized controlled trial; Level of evidence, 1.
Methods: Athletes playing volleyball, basketball, or handball with patellar tendinopathy for 3 to 12 months were randomized into the ESWT or placebo group during the first half of the season. The ESWT group received 3 ESWT treatments while the placebo group received sham ESWT. In-season follow-up measurements were 1, 12, and 22 weeks after treatment. The primary outcome was severity of patellar tendinopathy determined with the Victorian Institute of Sport Assessment–Patella (VISA-P) questionnaire. Secondary outcome measures were pain during activities of daily living and sports and after functional knee-loading tests rated on a visual analog scale and subjective improvement. Multilevel analyses were performed to determine differences between groups over time.
Results: Of the 127 symptomatic athletes invited to participate, 62 were eligible, gave consent, and were randomized into the ESWT (n = 31) or placebo group (n = 31). Mean VISA-P scores before and 1, 12, and 22 weeks after treatment were 59.4 (±11.7), 66.8 (±16.2), 66.7 (±17.5), and 70.5 (±18.9) for the ESWT group and 62.4 (±13.4), 66.3 (±19.0), 68.9 (±20.3), and 72.7 (±18.0) for the placebo group. For the VISA-P, there was a significant effect for time (P < .01) but no treatment × time interaction effect (P = .82). The same pattern was seen in visual analog scale pain scores. One week after final treatment, significantly more athletes in the ESWT group reported subjective improvement (65% vs 32%; χ2 = 6.46, P = .01). This was the only difference noted between the 2 groups.
Conclusion: Extracorporeal shockwave therapy as a solitary treatment during the competitive season has no benefit over placebo treatment in the management of actively competing jumping athletes with patellar tendinopathy who have symptoms for less than 12 months.
Vertical ground reaction force (VGRF) parameters have been implicated as a cause of several running-related injuries. However, no systematic review has examined this relationship.
We systematically ...reviewed evidence for a relation between VGRF parameters and specific running-related injuries.
MEDLINE, Web of Science and EMBASE databases were searched. Two independent assessors screened the articles and rated the methodological quality. The 3 key VGRF parameters we measured were vertical loading rate, impact/passive peak (Fz1) and propulsive/active peak (Fz2). Standardised mean differences of these parameters were calculated using a random-effects model. Meta-regression was performed using injury type, study type and methodological quality as factors.
The search yielded 2016 citations and 18 met the inclusion criteria for the systematic review. The loading rate was higher in studies that included patients with a history of stress fractures and patients with all injury types, both compared with controls. Only studies that included patients with a history of symptoms at the time of kinetic data collection showed higher loading rates overall in cases than in controls. There were no differences between injured subjects and controls for the active and passive peaks of the VGRF.
The loading rate is higher in respondents with a history of stress fractures than in respondents without running injuries. Owing to the absence of prospective studies on other injury types, it is not possible to draw definite conclusions regarding their relation with loading rate.
ABSTRACT
Aims
To explore the effect of an online self‐management program in secondary care for men with lower urinary tract symptoms (LUTS).
Methods
We performed a prospective nonrandomized ...double‐cohort pilot study of consecutive adult men referred with uncomplicated LUTS to three urology outpatient departments. Men in both cohorts received care as usual from a urologist, but men in the intervention cohort also had access to an online self‐management program. Outcomes were assessed after 6 and 12 weeks: LUTS severity was assessed with the International Prostate Symptom Score (IPSS), the Overactive Bladder Questionnaire (OABq), and the Perceived Global Impression of Improvement (PGI‐I). The main outcome of interest was a clear improvement in the PGI‐I scores (“much better” or “very much better”).
Results
Age, symptom severity, and quality of life scores were comparable between the intervention (n = 113) and standard care (n = 54) cohorts. Clear improvement in the PGI‐I scores was reported after 12 weeks in 19.4% and 26.1% of men in the intervention and standard care cohorts, respectively. However, logistic regression analysis indicated that the difference between cohorts was not significant. Multivariable linear regression analysis also indicated no significant differences between cohorts for the IPSS or the OABq score at either assessment point. Notably, the uptake of the intervention was low (53%).
Conclusions
We found no significant benefit from adding an online self‐management program to standard care for men with LUTS, probably due to the low uptake of the intervention that may have resulted from the timing in the care pathway.
•Peak rearfoot eversion is significant in ITBS, PT and PTTD but not in AT and PF.•Greater internal knee rotation is a risk factor for ITBS.•The meta-analysis shows conflicting evidence on hip ...adduction in ITBS.•Only few studies reported kinematic factors for PT, PF and PTTD in runners.
Abnormal kinematics have been implicated as one of the major risk factors for lower limb tendinopathy (LLT).
To systematically review evidence for kinematic risk factors for LLT in runners.
Individual electronic searches in PubMed, EMBASE and Web of Science were conducted. Two reviewers screened studies to identify observational studies reporting kinematic risk factors in runners with LLT compared to healthy controls. The Down and Black appraisal scale was applied to assess quality. A meta-analysis was performed provided that at least two studies with similar methodology reported the same factor.
Twenty-eight studies were included: Achilles tendinopathy (AT) (9), iliotibial band syndrome (ITBS) (17), plantar fasciopathy (PF) (2), patellar tendinopathy (PT) (1), posterior tibial tendon dysfunction (PTTD) (1). Eighteen studies were rated high-quality and ten medium-quality. The meta-analyses revealed strong evidence of higher peak knee internal rotation, moderate evidence of lower peak rearfoot eversion and knee flexion at heel strike and greater peak hip adduction in runners with ITBS. Very limited evidence revealed higher peak ankle eversion in runners with PF and PTTD or higher peak hip adduction in PT.
Peak rearfoot eversion was the only factor reported in all included LLTs; it is a significant factor in ITBS, PT and PTTD but not in AT and PF. More prospective studies are needed to accurately evaluate the role of kinematic risk factors as a cause of LLT. Taken together, addressing rearfoot kinematic and kinematic chain movements accompanied by peak eversion should be considered in the prevention and management of LLT.
Purpose: We aimed to examine how supply source affects satisfaction with continence products and care among individuals with urinary incontinence (UI). Supply source was compared among pharmacies, ...national suppliers, and shops. The secondary aim was to compare participant characteristics between the three groups. Patients and Methods: A survey questionnaire was distributed via social media between April and June 2020. This included the international consultation on incontinence questionnaire (ICIQ) UI short form (ICIQ-UI-SF), the ICIQ-PadPROM, and the ICIQ-LUTSqol, together with questions about respondent characteristics and satisfaction with continence products. Results: Of the 1045 respondents, 706 fully completed and 339 partially completed the survey. Among these, 322 (45.6%), 199 (28.1%), and 185 (26.2%) made purchases from shops, national suppliers, and pharmacies, respectively. The mean ICIQ-UI-SF sum scores were comparable for the pharmacy (13.3 + or - 3.7) and national supplier (13.8 + or - 3.5) groups, but were significantly lower for the shop group (12.0 + or - 3.3). Mean sum scores for satisfaction with continence products and satisfaction with continence care were also significantly lower in the shop group (7.9 + or - 2.6 and 6.4 + or - 2.7, respectively) compared with the pharmacy (9.1 + or - 2.7 and 7.9 + or - 2.6, respectively) and national supplier (9.3 + or - 2.6 and 8.1 + or - 3.0, respectively) groups. There were no statistically significant differences in the ICIQ-PadPROM and ICIQ-LUTSqol scores. Respondents' characteristics were similar, apart from the significantly lower number of males in the shop group. Conclusion: Satisfaction with continence products and continence care is lower for people with UI who purchase materials from a shop than from a pharmacy or national supplier.

Based on complaints that patients with urinary incontinence were not receiving the correct medical aids, the Dutch Ministry of Health, Wellbeing, and Sports requested further exploration. This ...resulted in a new framework based on considering individual activities of daily living when providing continence products. We aimed to explore the expectations of pharmacy staff regarding this new framework for continence care in the Netherlands and to establish the facilitators and barriers associated with that care. In total, 15 participants from 7 different pharmacies participated in 2 focus groups. Data analysis was by thematic content analysis. Pharmacy employees were positive about the idea of considering individual daily activities when providing continence products in the new framework, but they did have some reservations about the feasibility of implementation in daily practice. Barriers to optimal continence care included low reimbursement for patients with incontinence, especially with non-standard needs, and poor communication between the various stakeholders in continence care. Efforts must be extended to review the current reimbursement system and to change the policies and information provided by stakeholders in continence care, before the new framework will make a real impact in clinical practice.
Abstract Objectives The primary aim of this study is to investigate the effect of the use of a patellar strap on knee joint proprioception in both healthy participants and in patients with patellar ...tendinopathy (PT). Secondary aims are to examine whether there is a difference in effectiveness of the use of a patellar strap between participants with low and high proprioceptive acuity and if possible predictors of effectiveness can be determined. Design Case-control. Methods The threshold to detect passive motion with and without a patellar strap was assessed in 22 healthy participants and 21 unilateral PT patients. Results The results from the mixed model analysis show that in both groups of participants a small but statistically significant improvement in proprioception was found, primarily in those who had low proprioceptive acuity. A notable finding was that in the symptomatic leg of the PT group no improvement in proprioception by wearing a strap could be determined. Male gender and having fewer symptoms were possible predictors of effectiveness in PT patients. Conclusions As proprioception plays a role in optimising movements and reducing load to joint-related structures like tendons and ligaments, it is considered an important protection mechanism. Although the improvements in proprioception as a result of wearing the strap are small, it might be that the use of a patellar strap can potentially play a role in injury prevention since poor proprioception can be a risk factor for (re)-injury.
To determine the proportion of participants of a running program for novice runners that discontinued running and investigate the main reasons to discontinue and characteristics associated with ...discontinuation.
Prospective cohort study.
The study included 774 participants of Start to Run, a 6-week running program for novice runners. Before the start of the program, participants filled-in a baseline questionnaire to collect information on demographics, physical activity and perceived health. The 26-weeks follow-up questionnaire was used to obtain information on the continuation of running (yes/no) and main reasons for discontinuation. To determine predictors for discontinuation of running, multivariable logistic regression was performed.
Within 26 weeks after the start of the 6-week running program, 29.5% of the novice runners (n=225) had stopped running. The main reason for discontinuation was a running-related injury (n=108, 48%). Being female (OR 1.74; 95% CI 1.13–2.68), being unsure about the continuation of running after the program (OR 2.06; 95% CI 1.31–3.24) and (almost) no alcohol use (OR 1.62; 95%CI 1.11–2.37) were associated with a higher chance of discontinuation of running. Previous running experience less than one year previously (OR 0.46; 95% CI 0.26–0.83) and a higher score on the RAND-36 subscale physical functioning (OR 0.98; 95% CI 0.96–0.99) were associated with a lower chance of discontinuation.
In this group of novice runners, almost one-third stopped running within six months. A running-related injury was the main reason to stop running. Women with a low perceived physical functioning and without running experience were prone to discontinue running.
App-based treatment for urinary incontinence is a proven effective and cost-effective alternative to care as usual, but successful implementation requires that we identify and address the barriers ...and facilitators associated with app use.
The goal of the research was to explore the factors influencing app-based treatment for urinary incontinence and identify which barriers or facilitators are associated with treatment success or failure.
We used a sequential explanatory mixed methods design to connect the results of a randomized controlled trial with data from semistructured interviews. This previous RCT had shown the noninferiority of app-based treatment compared with care as usual for urinary incontinence over 4 months. Participants who reported success or failure with app-based treatment, as measured by the change in International Consultation on Incontinence Modular Questionnaire Urinary Incontinence Short Form symptom score, were selected for telephone interview by purposive sampling (n=17). This study reports mainly on the qualitative component of our mixed methods study. Qualitative analyses were conducted in two ways. First, we analyzed the qualitative data of all interviewed participants and discussed the relationships between the main themes. Second, the experiences between the success (n=9) and failure group (n=8) were compared and contrasted to explore factors that were positively or negatively associated with the quantitative effect of app-based treatment. These factors were then interpreted as barriers to and facilitators of successful app-based treatment.
Four interrelated themes were identified as affecting the app based treatment effect: adherence, personal factors, app factors, and awareness. Qualitative analyses of the relationships between the themes showed that adherence-related factors directly influenced treatment effect in both a positive and negative matter. In turn, adherence was also positively and negatively influenced by the other 3 themes. Additionally, awareness was positively influenced by the treatment effect. Within these themes, several factors were identified that acted as barriers (eg, unrealistic expectation of time investment and interfering personal circumstances), facilitators (eg, strict integration of exercises and prior pelvic floor muscle therapy), or both (eg, personality traits and increased awareness of symptoms).
This study shows that the effect of app-based treatment for urinary incontinence is mainly influenced by adherence, which in turn is affected by personal factors, app-based factors, and awareness. The identified factors could function as both facilitators and barriers depending on the user and interaction with other themes. Insight into these facilitators and barriers could lead to improved implementation and increased treatment effectiveness by targeting women most likely to benefit and through further development of the app.
