Q
Q angle angle subtended by a line drawn to the vertical bisection of femur and a line drawn from the lateral margin of pelvis to the sagittal plane of the knee joint (Figure Q1); normally 15 ° in men (>15 ° in women due to wider female pelvis); excessive pronators show an increased Q angle

QT interval see electrocardiogram
quadratus plantae see flexor accessorius
quadriceps femoris group of hip flexor muscles located on anterior thigh; i.e. vasti (vastus medialis, lateralis and intermedius) and rectus femoris; tendons unite to form quadriceps tendon which contains the patella, and inserts into the tibial tubercle inferior to the anterior aspect of the knee joint; quadriceps femoris muscles are subserved by the femoral nerve and act together to extend the knee and flex the hip joints
quadriceps reflex see reflex, patellar
quadriceps strain acute/chronic anterior thigh muscle strain
quadriplegia motor paralysis of all four limbs
qualitative gait analysis see gait, qualitiative gait analysis
Quality Outcomes Framework for Diabetes Mellitus (2006); QOFDM pharmacological management targets of patients with diabetes mellitus, to prevent/minimize late-stage secondary complications; recommends that all diabetic patients should be medicated with one blood glucose-regulating drug, three antihypertensive agents, one cholesterol-lowering drug and aspirin
quantitative gait analysis see gait, quantitative gait analysis
quarters sections of a shoe upper covering (medial, lateral and dorsal aspects of) midfoot, and (medial and lateral aspects of) rearfoot (without impinging on inferior malleolar margins) and heel; heel quarters are reinforced by the heel counter, to enhance midtarsal and subtalar joint function, and prevent mediolateral or anteroposterior rearfoot drift during gait; closeness of fit of the quarters is complemented by the shoe-retaining mechanism; shoe fit is always compromised if quarters have become worn (see Figures F4 and F6)
quaternary ammonium compounds types of chemical disinfecting agent with surfactant and detergent properties, e.g. cetrimide, which is active against Gram-positive bacteria, but which is tissue-toxic and readily inactivated by the presence of organic compounds (see Table C10)
quinine cinchona derivative (antimalarial agent) with antipyretic and analgesic actions; used to treat muscle cramps (e.g. reduces night cramps in 25% of cases), myopathies and atrial fibrillation
Quinoderm, Quinoped topical treatments for skin fungal infections, with antiseptic, keratolytic and antifungal actions
