Positional weakness
The apparent weakness of a muscle when tested in a shortened range of motion. This is a normal phenomenon of a muscle’s length-tension curve. To differentiate positional weakness from general muscle weakness, and assess strength accurately, the muscle must be tested throughout its entire range of motion.

Weak dominance
In health care management a strategy that provides a more effective but also a more costly solution to a problem than an alternative.

Waxing-up
In dentistry, the shaping of wax around the contours of a trial denture or cast restoration.

Bone wax
A polymer used to fill defects in damaged body parts and to control bleeding from injured bone, e.g., in orthopedic surgery. Its use is occasionally associated with side effects, including the formation of foreign-body reactions or the development of infections.

Truncated exponential waveform
A defibrillation waveform that rises sharply to a peak voltage and then is abruptly cut off and returns to zero.
-
Monophasic waveform
A waveform used by some defibrillators that delivers a single shock of positive energy to the myocardium.
-
Damped sinusoidal waveform
A defibrillation waveform that rises sharply to a peak voltage and then returns gradually to zero.
-
Biphasic waveform
A waveform used by some defibrillators that discharges energy in two phases (first positive, then negative). The shock applied by a biphasic defibrillator uses 30-40% less peak current at the same applied energy level than a monophasic defibrillator and is both less injurious to the heart and more likely to terminate ventricular fibrillation.

Waveform
The shape or the representation of a signal, e.g., in cardiology, the shape of the electrical shock used in cardioversion or defibrillation. Measurement of the distance between two wavelengths. When exploring the nature of waves, one fundamental aspect to consider is their shape. This shape, often referred to as the waveform, depicts the graphical representation…

Ultrasonic wave
A sound wave of greater frequency than 20 kHz. These waves do not produce sound audible to the human ear.
