The test consists of a pre\u2010exhaustion exercise protocol combined with a single\u2010leg hop. Nineteen male patients with ACL reconstruction (mean time after operation 11\u00a0months) who exhibited normal single\u2010leg hop symmetry values (\u226590% compared with the non\u2010involved extremity) were tested for one\u2010repetition maximum (1 RM) strength of a knee\u2010extension exercise. The patients then performed single\u2010leg hops following a standardised pre\u2010exhaustion exercise protocol, which consisted of unilateral weight machine knee\u2010extensions until failure at 50% of 1 RM. Although no patients displayed abnormal hop symmetry when non\u2010fatigued, 68% of the patients showed abnormal hop symmetry for the fatigued test condition. Sixty\u2010three per cent exhibited 1 RM strength scores of below 90% of the non\u2010involved leg. Eighty\u2010four percent of the patients exhibited abnormal symmetry in at least one of the tests. Our findings indicate that patients are not fully rehabilitated 11\u00a0months after ACL reconstruction. It is concluded that the pre\u2010exhaustion exercise protocol, combined with the single\u2010leg hop test, improved testing sensitivity when evaluating lower\u2010extremity function after ACL reconstruction. For a more comprehensive evaluation of lower\u2010extremity function after ACL reconstruction, it is therefore suggested that functional testing should be performed both under non\u2010fatigued and fatigued test conditions.<\/jats:p>","DOI":"10.1007\/s00167-004-0518-4","type":"journal-article","created":{"date-parts":[[2004,5,7]],"date-time":"2004-05-07T14:26:15Z","timestamp":1083939975000},"page":"350-356","source":"Crossref","is-referenced-by-count":89,"title":["Ability
