Torques in knee extension and flexion and surface\n                    electromyograms from the quadriceps, medial hamstring, and medial gastrocnemius\n                    muscles were simultaneously recorded. The uninjured limb served as a control for\n                    each patient. Before generation of flexion torque, the gastrocnemius muscle was\n                    electrically activated significantly earlier in posterior cruciate\n                    ligament-deficient knees than in uninjured knees at each velocity. However, we\n                    could not find any significant differences between the posterior cruciate\n                    ligament-deficient and uninjured knees in torque curves and electromyelograms of\n                    the quadriceps and hamstring muscles. This study suggests that early contraction\n                    of the gastrocnemius muscle may be a part of a compensatory mechanism in\n                    posterior cruciate ligament-deficient knees.<\/jats:p>","DOI":"10.1177\/03635465980260051801","type":"journal-article","created":{"date-parts":[[2017,7,19]],"date-time":"2017-07-19T00:35:21Z","timestamp":1500424521000},"page":"710-714","source":"Crossref","is-referenced-by-count":22,"title":["Compensatory Muscle Activity in the Posterior Cruciate                    Ligament-Deficient Knee During Isokinetic Knee Motion"],"prefix":"10.1177","volume":"26","author":[{"given":"Masayuki","family":"Inoue","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Hokkaido University School of\r                        Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazunori","family":"Yasuda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Hokkaido University School of\r                        Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masatomo","family":"Yamanaka","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, College of Medical Technology, Hokkaido\r                        University, Sapporo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuhiko","family":"Wada","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, College of Medical Technology, Hokkaido\r                        University, Sapporo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoshi","family":"Kaneda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Hokkaido University School of\r                        Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1998,9,1]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354658401200102"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.2165\/00007256-198401060-00002"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354658100900402"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198365030-00004"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/036354658401200409"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.64B1.7068728"},{"key":"e_1_2_1_8_1","first-page":"826","article-title":"Isokinetic torque of quadriceps in patients with untreated\n                        anterior cruciate ligament injury of the knee joint [in\n                        Japanese]","volume":"67","year":"1993","unstructured":"Ikeda H.: Isokinetic torque of quadriceps in patients with untreated anterior cruciate ligament injury of the knee joint [in Japanese].
