Sensitivity and specificity of Rinne tuning fork test.
the site of the placenta. Administration ofanti-D immunoglobulin is routine after invasive procedures in Rh negative patients but is not appropriate for those already sensitised, in whom it would be ineffective.'5 In patients undergoing intra-uterine transfusions, however, fetomaternal haemorrhage may enhance maternal sensitisation. Not only might the disease be worsened in a subsequent pregnan...
متن کاملTuning Forks and Tests
The three tuning forks generally used include : 256 Hz, 512 Hz, 1024 Hz. Most common being 512Hz. 512 because It has appropriate decay time, Less overtones and lies in speech frequency. Compressing the prongs with fingers produces around 70 dB sound and hitting against Knee or elbow 90dB. A prediction of air-bone gap can be made if tuning forks of 256, 512 and 1024 Hz are used. • Rinne test equ...
متن کاملRinne revisited: steel versus aluminum tuning forks.
OBJECTIVE (1) Determine whether tuning fork material (aluminum vs stainless steel) affects Rinne testing in the clinical assessment of conductive hearing loss (CHL). (2) Determine the relative acoustic and mechanical outputs of 512-Hz tuning forks made of aluminum and stainless steel. STUDY DESIGN Prospective, observational. SETTING Outpatient otology clinic. SUBJECTS AND METHODS Fifty su...
متن کاملRinne test: does the tuning fork position affect the sound amplitude at the ear?
BACKGROUND Guidelines and text-book descriptions of the Rinne test advise orienting the tuning fork tines in parallel with the longitudinal axis of the external auditory canal (EAC), presumably to maximise the amplitude of the air conducted sound signal at the ear. Whether the orientation of the tuning fork tines affects the amplitude of the sound signal at the ear in clinical practice has not ...
متن کاملThe otologist's tuning fork examination--are you striking it correctly?
OBJECTIVE To determine if the manner in which a tuning fork is activated affects its vibrational response. STUDY DESIGN Diagnostic test assessment. SETTING Hearing Center of Excellence laboratory. SUBJECTS AND METHODS A Polytec OFV-5000 scanning vibrometer was used to measure the vibrational response of 256-Hz, 512-Hz, and 1024-Hz tuning forks after activation. The tuning forks were activ...
