Maximal strength was markedly lower in the presence of an effusion, and aspiration of the effusion produced a 13.6% increase in strength (p less than 0.01). A further, small increase of 8% was recorded after intra-articular lignocaine injection. Isometric strength and surface integrated EMG correlated well in six patients. Two reflex mechanisms seem to inhibit quadriceps innervation in the presence of a persistent knee effusion, one mediated by pressure sensitive receptors, the other still unknown. Joint aspiration and systemic or intra-articular anti-inflammatory drug treatments are advised before any programme of quadriceps training to allow maximum effects to be achieved. <\/jats:p>","DOI":"10.1302\/0301-620x.70b4.3403614","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T11:43:34Z","timestamp":1519213414000},"page":"635-638","source":"Crossref","is-referenced-by-count":97,"title":["Knee effusion and reflex inhibition of the quadriceps.
