Wheel alignment, which is sometimes referred to as breaking or tracking, is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications. [1] The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true (without "pulling" to one ...
Misalignment of teeth creates difficulties in head and neck functions related to chewing, [6] [7] [8] swallowing, breathing, speech articulation [6] [7] [8] and lip closure/posture. [ 13 ] Affected individuals may also experience TMJ pain and dysfunction, [ 7 ] [ 14 ] which negatively affect the quality of life.
Excessive rotational misalignment of the foot is compensated by internal rotation of the residual hip joint. [63] Proper alignment of the transtibial prosthesis socket significantly reduced the loading on the intact limb during an 11-meter walk test, indicating that a misaligned limb could have drastic long-term consequences on the sound side ...
Vibration in automobiles may occur for many reasons, such as wheel unbalance, imperfect tire or wheel shape, brake pulsation, and worn or loose driveline, suspension, or steering components. Unbalance can result from collision-induced wheel deformations, uneven tire wear, or a shift of the tire on the rim.
Surgery may be necessary to treat misalignment of the hip (osteotomy of the pelvis or the collum femoris) and, in some cases, malformation (e.g., genu varum or genu valgum). [19] In some cases, total hip replacement may be necessary. However, surgery is not always necessary or appropriate. [20]
Historically, the detection of spinal misalignment (subluxations) by the chiropractic profession has relied on X-ray findings and physical examination. At least two of the following four physical signs and/or symptoms must be documented [how?] to qualify for reimbursement [further explanation needed]: Pain and tenderness; Asymmetry/misalignment
Neurological soft signs (NSS) are a group of minor non-focal neurological signs that include synkinesis. [3] Other soft signs including clumsiness, and loss of fine motor movement are also commonly found in schizophrenia. [4] NSS likely reflect impairments in sensory integration, motor coordination, and the carrying out of complex motor tasks. [3]
When a wheel is set up to have some camber angle, the interaction between the tire and road surface causes the wheel to tend to want to roll in a curve, as if it were part of a conical surface (camber thrust). This tendency to turn increases the rolling resistance as well as increasing tire wear. A small degree of toe (toe-out for negative ...
