MBLEx contraindication questions may involve the application, not just the client's diagnosis. Always ask whether the tool changes pressure, temperature, skin stress, circulation demand, sensation requirements or contamination risk.
Hot packs, stones, paraffin and other warming applications require intact enough sensation to provide feedback, appropriate skin/circulatory status, safe temperature and duration, and ongoing checks. Avoid placing heat over acute injury/inflammation when heat would worsen symptoms, areas with substantially impaired sensation, active bleeding, or other situations where thermal injury risk is unacceptable.
Cold can reduce sensation and alter local vascular responses. Use extra caution with impaired sensation, cold hypersensitivity/intolerance, compromised circulation and conditions in which cold provokes abnormal vascular response. Protect skin and monitor exposure.
Tools such as rollers, scraping-style instruments or percussion devices can concentrate force and make it easier to exceed what the client/tissue tolerates. Avoid use over acute injury, open/irritated skin, vulnerable vessels/nerves, suspected clot, unstable fracture or any region where the tool prevents precise control. A device does not make an unsafe technique safe.
Suction changes the mechanical load on skin and superficial tissues and commonly produces temporary discoloration. Screen skin integrity, bleeding/bruising risk, sensation and relevant medications. Obtain specific consent for expected marks and avoid misleading claims that discoloration represents “toxins leaving the body.”
Do not force unstable, acutely injured, recently operated, severely painful or medically restricted joints. Osteoporosis and other fragility conditions may require reduced leverage. Neurological symptoms during movement are a reason to stop and reassess.
Ask about allergy/sensitivity, use appropriate dilution/products, avoid eyes and mucous membranes, and consider pregnancy, asthma/scent sensitivity and skin conditions. “Natural” does not mean nonallergenic or universally safe.
Client risk + application risk = actual decision. A stable condition may still make one application inappropriate, while another gentle technique remains reasonable. MBLEx questions often reward this more specific reasoning.
