Final answer:
The three parameters manipulated in a diathermy treatment are voltage, pulse rate, and pulse width, tailored to achieve the desired therapeutic effects.
Step-by-step explanation:
In diathermy treatment, three parameters are typically manipulated to achieve therapeutic effects:
- Voltage: This determines the potential difference that drives the current through the tissues.
- Pulse Rate: The frequency at which the electrical pulses are delivered, which affects the heating and muscle stimulation.
- Pulse Width: The duration of each electrical pulse, affecting the amount of heat produced and depth of tissue affected.
Adjusting these parameters allows the practitioner to tailor the treatment according to the patient's needs and the intended therapeutic outcomes.
