![]() A systematic review requires two independent reviewers selecting studies for inclusion. It is advisable to use a protocol and to lay down the inclusion and exclusion criteria. The selection of articles for a systematic review is very demanding. These programmes allow for deduplication2. It also depends on the time and manpower available.įor screening and selection search results can be exported from the various databases to bibliographic software programmes such as EndNote, Zotero or Mendeley. This is related to the scope of the search query and number of studies on the subject. The question is often asked how many results is usual. Searches can produce very large numbers of results. Search terms are linked to search queries by means of the Boolean operators OR, AND and NOT and adapted for the various bibliographic databases if necessary. Both are necessary for the fullest possible result. These can be free terms or terms from a word system such as a thesaurus. Search terminology and search queriesįinding the right and relevant search terms is an important part of the search process. Which databases you use depends on your subject, see the subject guides or Find Databases. Bibliographic databases refer to relevant literature of a certain type (peer reviewed, dissertations, grey literature) or in a certain field. When searching for reviews, it is necessary to use several bibliographic databases. A useful tool is PICO:Ī research question can also be formulated by using the more general questions What? How? Why? Who? Where? Bibliografical databases Research questionĪ clear research question is a prerequisite for a qualitative search strategy and a targeted article selection. Cochrane Reviews and Campbell Reviews are considered a gold standard when it comes to methodology. The aim is to find every studie of likely relevance making a sensitive search strategy a necessity. Difference is in depth and accurancy used in every stept. Searching for research studies mostly requires the same steps as a usual literature search. In a meta-analysis, the systematic review is followed by a statistical analysis of the results from the studies used. This is a systematic review Een aparte categorie vormt de meta-analyse. A distinct category is the meta-analysis. ![]() Most common are the critical review, literature review, scoping review, state-of-the-art review, systematic review. Clinicians should be aware of these characteristics to help in the management of running injuries and advice on training.There are many types of systematic reviews, all varying in terms of perspective, purpose, approach, methods, and the time and resources used to conduct them. The selection of review type is wholly dependent on the research question. There are differences in kinematic and kinetic characteristics between foot-strike patterns when running. For kinetic variables, the meta-analysis revealed that rearfoot strikers had higher vertical loading rates compared to forefoot strikers. 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. ![]() 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 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. Sixteen studies were included in the final analysis. A meta-analysis with a random-effects model was used to combine the data from the included studies. Two independent reviewers evaluated the risk of bias. 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. Strike patterns during running have received attention in the recent literature due to their potential mechanical differences and associated injury risks.Įlectronic databases (MEDLINE, Embase, LILACS, SciELO, and SPORTDiscus) were searched through July 2014. To determine the biomechanical differences between foot-strike patterns used when running. ![]()
