  1. NSAIDs reduce pain and inflammation primarily by inhibiting which enzyme?

    Answer: Cyclooxygenase (COX)

    NSAIDs inhibit cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever.

  2. Which category of medication is most commonly injected into joints (intra-articular injection) to reduce inflammation in orthopedic conditions such as knee osteoarthritis?

    Answer: Corticosteroids

    Corticosteroids such as triamcinolone or methylprednisolone are injected intra-articularly to reduce synovial inflammation in conditions like knee osteoarthritis.

  3. A patient taking long-term corticosteroids presents for physical therapy; which musculoskeletal side effect should the OCS be most vigilant about?

    Answer: Osteoporosis and increased fracture risk

    Long-term corticosteroid use suppresses osteoblast activity and increases osteoclast activity, leading to osteoporosis and significantly elevated fracture risk.

  4. The gate control theory of pain proposes that non-painful sensory input can inhibit pain transmission at the spinal cord level; which treatment modality most directly applies this mechanism?

    Answer: Transcutaneous electrical nerve stimulation (TENS)

    TENS activates large-diameter Aβ fibers that inhibit pain signal transmission from small-diameter C and Aδ fibers at the dorsal horn, consistent with gate control theory.

  5. Central sensitization in chronic musculoskeletal pain is best described as:

    Answer: Amplified pain processing within the central nervous system independent of peripheral input

    Central sensitization involves amplified, persistent pain processing in the CNS characterized by allodynia, hyperalgesia, and wind-up that is disproportionate to peripheral tissue damage.

  6. Which assessment tool is most commonly used by OCS practitioners to screen for central sensitization features in chronic pain patients?

    Answer: Central Sensitization Inventory (CSI)

    The Central Sensitization Inventory (CSI) is a validated 25-item self-report questionnaire specifically designed to identify symptoms associated with central sensitization.
