What are the Main Running-Related Musculoskeletal Injuries?

BackgroundMusculoskeletal injuries occur frequently in runners and despite many studies about running injuries conducted over the past decades it is not clear in the literature what are the main running-related musculoskeletal injuries (RRMIs).ObjectiveThe aim of this study is to systematically review studies on the incidence and prevalence of the main specific RRMIs.MethodsAn electronic database search was conducted using EMBASE (1947 to October 2011), MEDLINE (1966 to October 2011), SPORTDiscus™ (1975 to October 2011), the Latin American and Caribbean Center on Health Sciences Information (LILACS) [1982 to October 2011] and the Scientific Electronic Library Online (SciELO) [1998 to October 2011] with no limits of date or language of publication. Articles that described the incidence or prevalence rates of RRMIs were considered eligible. Studies that reported only the type of injury, anatomical region or incomplete data that precluded interpretation of the incidence or prevalence rates of RRMIs were excluded. We extracted data regarding bibliometric characteristics, study design, description of the population of runners, RRMI definition, how the data of RRMIs were collected and the name of each RRMI with their rates of incidence or prevalence. Separate analysis for ultra-marathoners was performed. Among 2924 potentially eligible titles, eight studies (pooled n = 3500 runners) were considered eligible for the review. In general, the articles had moderate risk of bias and only one fulfilled less than half of the quality criteria established.ResultsA total of 28 RRMIs were found and the main general RRMIs were medial tibial stress syndrome (incidence ranging from 13.6% to 20.0%; prevalence of 9.5%), Achilles tendinopathy (incidence ranging from 9.1% to 10.9%; prevalence ranging from 6.2% to 9.5%) and plantar fasciitis (incidence ranging from 4.5% to 10.0%; prevalence ranging from 5.2% to 17.5%). The main ultra-marathon RRMIs were Achilles tendinopathy (prevalence ranging from 2.0% to 18.5%) and patellofemoral syndrome (prevalence ranging from 7.4% to 15.6%).ConclusionThis systematic review provides evidence that medial tibia stress syndrome, Achilles tendinopathy and plantar fasciitis were the main general RRMIs, while Achilles tendinopathy and patellofemoral syndrome were the most common RRMIs for runners who participated in ultra-marathon races.

Current evidence does not support the use of Kinesio Taping in clinical practice: a systematic review

QUESTIONS Is Kinesio Taping more effective than a sham taping/placebo, no treatment or other interventions in people with musculoskeletal conditions? Is the addition of Kinesio Taping to other interventions more effective than other interventions alone in people with musculoskeletal conditions? DESIGN Systematic review of randomised trials. PARTICIPANTS People with musculoskeletal conditions. INTERVENTION Kinesio Taping was compared with sham taping/placebo, no treatment, exercises, manual therapy and conventional physiotherapy. OUTCOME MEASURES Pain intensity, disability, quality of life, return to work, and global impression of recovery. RESULTS Twelve randomised trials involving 495 participants were included in the review. The effectiveness of the Kinesio Taping was tested in participants with: shoulder pain in two trials; knee pain in three trials; chronic low back pain in two trials; neck pain in three trials; plantar fasciitis in one trial; and multiple musculoskeletal conditions in one trial. The methodological quality of eligible trials was moderate, with a mean of 6.1 points on the 10-point PEDro Scale score. Overall, Kinesio Taping was no better than sham taping/placebo and active comparison groups. In all comparisons where Kinesio Taping was better than an active or a sham control group, the effect sizes were small and probably not clinically significant or the trials were of low quality. CONCLUSION This review provides the most updated evidence on the effectiveness of the Kinesio Taping for musculoskeletal conditions. The current evidence does not support the use of this intervention in these clinical populations. PROSPERO registration: CRD42012003436.

Previous injuries and some training characteristics predict running-related injuries in recreational runners: a prospective cohort study

QUESTIONS What is the incidence of running-related injuries (RRIs) in recreational runners? Which personal and training characteristics predict RRIs in recreational runners? DESIGN Prospective cohort study. PARTICIPANTS A total of 200 recreational runners answered a fortnightly online survey containing questions about their running routine, races, and presence of RRI. These runners were followed-up for a period of 12 weeks. OUTCOME MEASURES The primary outcome of this study was running-related injury. The incidence of injuries was calculated taking into account the exposure to running and was expressed by RRI/1000 hours. The association between potential predictive factors and RRIs was estimated using generalised estimating equation models. RESULTS A total of 84 RRIs were registered in 60 (31%) of the 191 recreational runners who completed all follow-up surveys. Of the injured runners 30% (n=18/60) developed two or more RRIs, with 5/18 (28%) being recurrences. The incidence of RRI was 10 RRI/1000 hours of running exposure. The main type of RRI observed was muscle injuries (30%, n=25/84). The knee was the most commonly affected anatomical region (19%, n=16/84). The variables associated with RRI were: previous RRI (OR 1.88, 95% CI 1.01 to 3.51), duration of training although the effect was very small (OR 1.01, 95% CI 1.00 to 1.02), speed training (OR 1.46, 95% CI 1.02 to 2.10), and interval training (OR 0.61, 95% CI 0.43 to 0.88). CONCLUSIONS Physiotherapists should be aware and advise runners that past RRI and speed training are associated with increased risk of further RRI, while interval training is associated with lower risk, although these associations may not be causative.

Assessment of cross-cultural adaptations and measurement properties of self-report outcome measures relevant to shoulder disability in Portuguese: a systematic review

OBJECTIVES To evaluate the quality of the adaptation procedures as well as the clinimetric testing of the shoulder disability questionnaires available in Portuguese that has occurred for each adaptation. METHODS Systematic literature searches on MEDLINE, EMBASE, CINAHL, SCIELO and LILACS were performed to identify relevant studies. Data on the quality of the cross-cultural adaptation procedures and clinimetric testing were extracted. All studies were evaluated according to the current guidelines for cross-cultural adaptation and measurement properties. RESULTS Seven different questionnaires adapted into Brazilian-Portuguese (DASH, WORC, SPADI, PSS, ASORS, ASES and UCLA) were indentified from eleven studies. Most of the studies performed the cross-cultural adaptation procedures following the recommendations from the guidelines. From a total of seven instruments, two were not tested for any measurement property (PSS and ASES) and two questionnaires (DASH and WORC) were evaluated for almost all of properties. None of the questionnaires were fully tested for their measurement properties. CONCLUSIONS Although most of the shoulder disability questionnaires have been properly adapted into Brazilian-Portuguese, some of them were either inadequately tested or not tested at all. It is recommended that only tested instruments can be used in clinical practice, as well as in research.

Incidence and risk factors of injuries in Brazilian elite handball players: A prospective cohort study

The aim of this study was to investigate the incidence and risk factors for handball injuries in Brazilian elite handball players. Overall, 339 athletes from 21 handball teams who participated in the two main Brazilian championships were followed up during a season. In total, 312 injuries were reported by 201 athletes. The injury incidence rate during training was 3.7/1000 h, and during matches was 20.3/1000 matches. Ankle (19.4%, n = 46) and knee (13.5%, n = 32) were the body regions most affected by traumatic injuries. Shoulders (44.0%, n = 33) and knee (26.7%, n = 20) were the body regions most affected by overuse injuries. Muscle injuries (27.1%, n = 68) was the traumatic injury type most reported. Tendinopathy (91.8%, n = 56) was the overuse injury type most observed. Previous injury (OR: 2.42, CI 95%: 1.51–3.89) and an additional match per week (OR: 1.31, CI 95%: 1.05–1.62) were associated with a higher risk of overuse injury. Female athletes (OR: 1.56, CI 95%: 1.08–2.25) and an additional hour of training per week (OR: 1.09, CI 95%: 1.02–1.15) were associated with a higher risk of traumatic injury. This study showed that athletes with previous injury have shown a high risk of developing an overuse injury.

A description of training characteristics and its association with previous musculoskeletal injuries in recreational runners: a cross-sectional study

BACKGROUND Running is one of the most popular physical activities in the world and the number of runners has increased over the past 40 years. One of the consequences of the growing running popularity is the increase of musculoskeletal injuries. OBJECTIVES To describe the routines, training characteristics and history of injury in recreational runners and to evaluate possible associations between the routines and training characteristics with previous musculoskeletal running-related injuries. METHODS A total of 200 runners participated in this study. The participants completed an electronic form containing questions about personal characteristics, running experience, training characteristics, type of running shoes, foot type and previous injuries history over the last 12 months. The data were analyzed descriptively as well as by using logistic regression models. RESULTS The majority of the runners was male, aged 43.0 (SD=10.5) years-old, have a body mass index of 24.2 (IQR=4.3) kg/m², and had training volume of 35.0 (IQR=28.0) kilometers per week. Fifty-five percent of runners had injuries over the last 12 months. The most prevalent injuries observed were tendinopathies and muscle injuries. The variable that showed an association with previous running-related injuries was running experience from 5 to 15 years (Odds Ratio (OR)=0.2; 95%CI=0.1 to 0.9). CONCLUSIONS The prevalence of running-related injuries over the last 12 months was 55%. The variable running experience was associated with the absence of previous musculoskeletal running-related injuries.

Biomechanical Differences of Foot-Strike Patterns During Running: A Systematic Review With Meta-analysis.

STUDY DESIGN Systematic review with meta-analysis. OBJECTIVES To determine the biomechanical differences between foot-strike patterns used when running. BACKGROUND Strike patterns during running have received attention in the recent literature due to their potential mechanical differences and associated injury risks. METHODS Electronic databases (MEDLINE, Embase, LILACS, SciELO, and SPORTDiscus) were searched through July 2014. Studies (cross-sectional, case-control, prospective, and retrospective) comparing the biomechanical characteristics of foot-strike patterns during running in distance runners at least 18 years of age were included in this review. Two independent reviewers evaluated the risk of bias. A meta-analysis with a random-effects model was used to combine the data from the included studies. RESULTS Sixteen studies were included in the final analysis. In the meta-analyses of kinematic variables, significant differences between forefoot and rearfoot strikers were found for foot and knee angle at initial contact and knee flexion range of motion. A forefoot-strike pattern resulted in a plantar-flexed ankle position and a more flexed knee position, compared to a dorsiflexed ankle position and a more extended knee position for the rearfoot strikers, at initial contact with the ground. In the comparison of rearfoot and midfoot strikers, midfoot strikers demonstrated greater ankle dorsiflexion range of motion and decreased knee flexion range of motion compared to rearfoot strikers. For kinetic variables, the meta-analysis revealed that rearfoot strikers had higher vertical loading rates compared to forefoot strikers. CONCLUSION There are differences in kinematic and kinetic characteristics between foot-strike patterns when running. Clinicians should be aware of these characteristics to help in the management of running injuries and advice on training.

Translation, Cross-cultural Adaptation, and Clinimetric Testing of Instruments Used to Assess Patients With Patellofemoral Pain Syndrome in the Brazilian Population

STUDY DESIGN Clinical measurement study. OBJECTIVES To cross-culturally adapt the Anterior Knee Pain Scale (AKPS), the Functional Index Questionnaire (FIQ), and the Pain Severity Scale (PSS) for patellofemoral pain syndrome (PFPS) into Brazilian Portuguese. This study also aimed to test the measurement properties of the AKPS, the FIQ, and the PSS, and the existing Brazilian Portuguese versions of the numeric pain rating scale (NPRS) and the Global Perceived Effect scale in a group with PFPS. BACKGROUND PFPS is a common condition. Therefore, translated, culturally adapted, and clinimetrically tested instruments for measuring PFPS are needed. METHODS The AKPS, FIQ, and PSS instruments were cross-culturally adapted into Brazilian Portuguese. The measurement properties of the AKPS, FIQ, PSS, NPRS, and Global Perceived Effect scale (internal consistency, ceiling and floor effects, and construct validity) were tested in 83 patients with PFPS. The reproducibility and responsiveness were tested in 52 patients with PFPS in a test-retest design, with follow-up testing at 48 to 72 hours and at 4 weeks after baseline. RESULTS The AKPS, the FIQ, and the PSS yielded adequate internal consistency (Cronbach alpha ranging from .75 to .87) and excellent reliability (intraclass correlation coefficients [model 2,1] ranging from 0.90 to 0.97). The AKPS and the PSS yielded very good agreement (standard error of measurement, 2.9% and 3.5%, respectively). The highest correlations were observed among the AKPS, the FIQ, and the PSS (Pearson r>0.60, P<.05). No floor or ceiling effects were observed for any of the instruments. Effect sizes used for measuring internal responsiveness ranged from moderate to high for all measures. The NPRS and the AKPS were the measures with the highest external responsiveness. CONCLUSION The Brazilian Portuguese versions of the AKPS, FIQ, PSS, NPRS, and Global Perceived Effect scale have acceptable measurement properties.

Reproducibility of the Portuguese version of the PEDro Scale

The objective of this study was to test the inter-rater reproducibility of the Portuguese version of the PEDro Scale. Seven physiotherapists rated the methodological quality of 50 reports of randomized controlled trials written in Portuguese indexed on the PEDro database. Each report was also rated using the English version of the PEDro Scale. Reproducibility was evaluated by comparing two separate ratings of reports written in Portuguese and comparing the Portuguese PEDro score with the English version of the scale. Kappa coefficients ranged from 0.53 to 1.00 for individual item and an intraclass correlation coefficient (ICC) of 0.82 for the total PEDro score was observed. The standard error of the measurement of the scale was 0.58. The Portuguese version of the scale was comparable with the English version, with an ICC of 0.78. The inter-rater reproducibility of the Brazilian Portuguese PEDro Scale is adequate and similar to the original English version.

Cross-cultural Adaptation and Measurement Properties of the Brazilian Portuguese Version of the Victorian Institute of Sport Assessment-Patella (VISA-P) Scale

STUDY DESIGN Clinical measurement. OBJECTIVES To translate, adapt, and test the measurement properties of the Brazilian Portuguese version of the Victorian Institute of Sport Assessment-Patella (VISA-P) questionnaire. BACKGROUND It is important to objectively measure symptoms and functional limitations related to patellar tendinopathy using outcome measures that have been validated in the language of the target population. Cross-cultural adaptations are also useful to enhance the understanding of the measurement properties of an assessment tool, regardless of the target language. METHODS The VISA-P questionnaire was translated into Brazilian Portuguese, culturally adapted, and titled VISA-P Brazil. It was then administered on 2 occasions with a 24- to 48-hour interval between them, and a third time after a month of physical therapy treatment. The following measurement properties were analyzed: internal consistency, test-retest reliability, agreement, construct validity, floor and ceiling effects, and responsiveness. RESULTS The VISA-P Brazil had high internal consistency (Cronbach α = .76; if item deleted, Cronbach α = .69-.78), excellent reliability and agreement (intraclass correlation coefficient = 0.91; 95% confidence interval: 0.85, 0.95; standard error of measurement, 5.2 points; minimal detectable change at the 90% confidence level, 12.2 points), and good construct validity (Pearson r = 0.60 compared to Lysholm). No ceiling and floor effects were detected for the VISA-P Brazil, and the responsiveness, based on 32 patients receiving physical therapy intervention for 1 month, demonstrated a large effect size of 0.97 (95% confidence interval: 0.68, 1.25). CONCLUSION The VISA-P Brazil is a reproducible and responsive tool and can be used in clinical practice and research to assess the severity of pain and disability of patients with patellar tendinopathy.
