• A. True
• B. False
• C. Not specified
• D. Sometimes

Answer: (A)

Contraindications are safety rules that say not to use a modality in certain conditions because it could cause harm. This definition centers on preventing risk to the patient by withholding a treatment when the situation makes it dangerous. For example, if there’s an acute infection, a bleeding risk, impaired sensation, or a condition like a pacemaker, many modalities would be avoided because using them could worsen the situation or cause injury. Some modalities have absolute contraindications (the treatment must not be used at all under those conditions), while others involve precautions or necessary modifications if used under supervision. The statement is true because contraindications identify exactly those scenarios where the modality should not be used to avoid harm.
