The Arndt-Schultz Law as applied to therapeutic modalities states that:
Answer: Weak stimuli excite, moderate stimuli enhance, and strong stimuli suppress physiological activity
The Arndt-Schultz Law states that weak stimuli excite, moderate stimuli enhance, and strong stimuli suppress physiological activity, guiding dosage decisions in therapeutic modalities.
The cryostretch technique uses which sequence of therapeutic applications?
Answer: Ice application until numbness, then stretching, then rewarming
Cryostretch involves applying ice until the area becomes numb, then performing stretching during the cold-induced analgesia phase to achieve greater range of motion with less pain.
Which ultrasound parameter is MOST critical to control when treating tissue adjacent to a metal implant?
Answer: Spatial average intensity (keep lower)
Spatial average intensity must be kept lower when treating near metal implants because metal conducts and concentrates ultrasound energy, risking localized tissue damage or burns.
Low-level laser therapy (LLLT) exerts its therapeutic effects primarily through which mechanism?
Answer: Photobiomodulation of cellular metabolic processes
Low-level laser therapy works through photobiomodulation, where specific wavelengths of light stimulate cellular metabolic processes and promote healing without significant thermal effects.
In fluidotherapy, heat is transferred to the body part through which mechanism?
Answer: Convection
Fluidotherapy transfers heat through convection, as the warm air-suspended cellulose particles continuously move around the body part, delivering heat to the tissue surface.
Russian current stimulation (2,500 Hz burst at 50 bursts/second) is MOST effective for which therapeutic goal?
Answer: Muscle re-education and strengthening
Russian stimulation at 2,500 Hz carrier frequency burst at 50 bursts/second produces strong, comfortable muscle contractions that are effective for muscle re-education and strengthening.
Paraffin bath therapy is MOST appropriately indicated for which condition?
Answer: Chronic arthritic conditions of the hands or feet
Paraffin bath is most appropriate for chronic arthritic conditions of the hands and feet, providing superficial heat that increases tissue extensibility and reduces stiffness.
