We performed a prospective observational clinical study of knee muscle strength and self-reported health during rehabilitation after unilateral knee soft-tissue injury in recreational sports. Forty-three patients performed isokinetic dynamometry and filled in the Short form Health Survey (SF-36) and the Oxford Knee Score questionnaires before and after 4 months of instructed home strengthening program. We observed significant improvement in peak torque deficit between two limbs during concentric extension (PTD<jats:sub>E<\/jats:sub>) and flexion, dynamic control ratio of the involved knee, most of the SF-36 subscales and the Oxford Knee Score values (<jats:italic toggle=\"yes\">P<\/jats:italic> \u2264\u20090.001). Dynamic control ratio of the uninvolved knee values remained below referential values and unchanged. Improvement of PTD<jats:sub>E<\/jats:sub> correlated positively with improvement of the bodily pain subscale of SF-36 score (<jats:italic toggle=\"yes\">r<\/jats:italic> = 0.51, <jats:italic toggle=\"yes\">P<\/jats:italic>\u2009&lt;\u20090.001). Receiver operating characteristic analysis indicated that reduction of pain by at least nine points predicts at least 10% reduction in PTD<jats:sub>E<\/jats:sub>, whereby the bodily pain change achieved poor (56%) sensitivity and good (86%) specificity as a rehabilitation success measure for recreational athletes after knee injury. Primary inferior eccentric strength of noninjured knee hamstrings might indicate increased risk of knee injury. Diminished perceived pain predicts strength improvement of the injured knee extensors with poor sensitivity and good specificity.<\/jats:p>","DOI":"10.1097\/mrr.0000000000000342","type":"journal-article","created":{"date-parts":[[2019,3,17]],"date-time":"2019-03-17T11:56:00Z","timestamp":1552823760000},"page":"168-173","source":"Crossref","is-referenced-by-count":4,"title":["Pain and outcome prediction in muscle strength rehabilitation after knee injury in recreational athletes"],"prefix":"10.1097","volume":"42","author":[{"given":"Du\u0161anka","family":"Marn-Vukadinovi\u0107","sequence":"first","affiliation":[{"name":"Outpatient Clinic, University Rehabilitation Institute Republic of Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nata\u0161a","family":"Bizovi\u010dar","sequence":"additional","affiliation":[{"name":"Outpatient Clinic, University Rehabilitation Institute Republic of Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ne\u017ea","family":"Majdi\u010d","sequence":"additional","affiliation":[{"name":"Outpatient Clinic, University Rehabilitation Institute Republic of Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaj","family":"Vidmar","sequence":"additional","affiliation":[{"name":"Outpatient Clinic, University Rehabilitation Institute Republic of Slovenia"},{"name":"Institute for Biostatistics and Medical Informatics, Faculty of Medicine, University of Ljubljana, Ljubljana"},{"name":"Department of Psychology, Faculty of Mathematics, Natural Sciences and Information Technologies, University of Primorska, Koper, Slovenia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20230918","doi-asserted-by":"crossref","first-page":"705","DOI":"10.1007\/s00167-009-0813-1","article-title":"Prevention of non-contact anterior cruciate ligament injuries in soccer players.
