Quadriceps strength in the three patient groups measured as a) maximal voluntary contraction (MVC) force and b) unpotentiated quadriceps twitch tension (TwQ). Quadriceps strength was reduced in both scoliosis and chronic obstructive pulmonary disease (COPD) patients compared with controls judged by MVC (p=0.02 and p=0.04, respectively) and, in the case of restrictive patients, by TwQ (p=0.013).
