Context: Quadriceps dysfunction is a common consequence of knee joint injury and disease, yet its causes remain elusive. Objective: To determine the effects pain on quadriceps strength activation to learn if simultaneous effusion affect magnitude dysfunction. Design: Crossover study. Setting: University research laboratory. Patients or Other Participants: Fourteen (8 men, 6 women; age = 23.6 ± 4.8 years, height 170.3 9.16 cm, mass 72.9 11.84 kg) healthy volunteers. Intervention(s): All participants were tested under 4 randomized conditions: normal knee, effused painful knee. Main Outcome Measure(s): (Nm/kg) (central ratio) assessed after each condition was induced. Results: highest differed from 3 experimental conditions (P < .05). No differences noted among for either variable > Conclusions: Both led dysfunction, but interaction 2 stimuli did not increase deficits. Therefore, can be considered equally potent in eliciting inhibition. Given that accompany numerous conditions, prevalence likely high.
