Although this likely represents a greater demand on the hip abductor muscles implicated in <jats:styled-content style=\"fixed-case\">GT<\/jats:styled-content>, no study has investigated activation of these muscles in <jats:styled-content style=\"fixed-case\">GT<\/jats:styled-content>. For this purpose, fine wire electrodes were inserted into the segments of the gluteus minimus and medius muscles, and surface electrodes placed on the tensor fascia lata, upper gluteus maximus, and vastus lateralis muscles of eight individuals with, and eight without, <jats:styled-content style=\"fixed-case\">GT<\/jats:styled-content>. Participants underwent six walking trials. Individual muscle patterns were compared between groups using a wavelet\u2010based linear effects model and muscle synergy analysis performed using non\u2010negative matrix factorization to evaluate muscle activation patterns, within\u2010 and between\u2010participant variability. Compared to controls, individuals with <jats:styled-content style=\"fixed-case\">GT<\/jats:styled-content> exhibited a more sustained initial burst of the posterior gluteus minimus and middle gluteus medius muscle segments. Two muscle synergies were identified; Synergy\u20101 activated in early\u2010mid stance and Synergy\u20102 in early stance. In <jats:styled-content style=\"fixed-case\">GT<\/jats:styled-content> participants, posterior gluteus minimus and posterior gluteus medius and tensor fascia lata contributed more to Synergy\u20101 active during the period of single leg support. Participants with <jats:styled-content style=\"fixed-case\">GT<\/jats:styled-content> exhibited reduced within\u2010participant variability of posterior gluteus medius and reduced between\u2010participant variability of anterior gluteus minimus and medius and upper gluteus maximus. In conclusion, individuals with <jats:styled-content style=\"fixed-case\">GT<\/jats:styled-content> exhibit modified muscle activation patterns of the hip abductor muscles during walking, with potential relevance for gluteal tendon loading.<\/jats:p>","DOI":"10.1111\/sms.12942","type":"journal-article","created":{"date-parts":[[2017,7,4]],"date-time":"2017-07-04T18:16:37Z","timestamp":1499192197000},"page":"686-695","source":"Crossref","is-referenced-by-count":38,"title":["Hip abductor muscle activity during walking in individuals with gluteal tendinopathy"],"prefix":"10.1111","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1344-1465","authenticated-orcid":false,"given":"K.","family":"Allison","sequence":"first","affiliation":[{"name":"Centre for HealthExercise and Sports Medicine Department of Physiotherapy The University of Melbourne  Parkville Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
