CCSP Adjunctive Sports Therapies 2 — Questions and Answers
Question 1: Which parameter is most important when selecting ultrasound frequency for treating a deep hip flexor strain in a football player?
- Output intensity in watts
- Tissue depth and desired penetration (Correct answer)
- Duty cycle percentage
- Transducer size
Correct answer: Tissue depth and desired penetration
Higher frequencies (3 MHz) penetrate superficially (~2 cm) while lower frequencies (1 MHz) reach deeper tissues (~5 cm), making depth selection critical for hip flexors.
Question 2: A wrestler presents with acute hamstring contusion. Which physiological effect of cryotherapy is MOST beneficial in the first 24 hours?
- Increased collagen synthesis
- Vasoconstriction reducing edema formation (Correct answer)
- Enhanced phagocyte activity
- Increased nerve conduction velocity
Correct answer: Vasoconstriction reducing edema formation
Cryotherapy-induced vasoconstriction limits secondary hypoxic injury and reduces edema formation during the acute inflammatory phase.
Question 3: Kinesio taping applied in a 'Y' strip over the quadriceps is PRIMARILY intended to:
- Restrict full knee flexion range of motion
- Facilitate muscle activation and reduce swelling (Correct answer)
- Provide rigid joint stabilization
- Compress the bursa to reduce friction
Correct answer: Facilitate muscle activation and reduce swelling
The Y-strip Kinesio tape technique lifts the skin to decompress lymphatic channels and facilitate muscle by altering sensory input.
Question 4: Interferential current therapy (IFC) uses two medium-frequency currents to produce a therapeutic beat frequency. The most common clinical range for pain modulation is:
- 1–10 Hz
- 80–150 Hz (Correct answer)
- 250–500 Hz
- 2000–4000 Hz
Correct answer: 80–150 Hz
Beat frequencies of 80–150 Hz activate large-diameter sensory fibers and are most effective for pain gating in clinical IFC applications.
Question 5: A distance runner complains of lateral knee pain. The MOST appropriate soft tissue technique to address iliotibial band tension as an adjunct to chiropractic care is:
- Passive stretching of the gastrocnemius
- Active Release Technique (ART) along the IT band (Correct answer)
- Ultrasound to the medial collateral ligament
- TENS over the patella
Correct answer: Active Release Technique (ART) along the IT band
ART targets adhesions and myofascial restrictions in the IT band through specific tension combined with active patient movement.
Question 6: When applying moist heat to a sprained ankle, the minimum contraindication to assess FIRST is:
- Patient's pain tolerance level
- Presence of acute inflammation or open wound (Correct answer)
- Time since the athlete's last meal
- Ambient room temperature
Correct answer: Presence of acute inflammation or open wound
Acute inflammation, open wounds, and impaired circulation are primary contraindications because heat exacerbates edema and risks thermal injury.
Question 7: In instrument-assisted soft tissue mobilization (IASTM), the proposed mechanism of producing therapeutic fibroblast activity involves:
- Creating localized controlled microtrauma to stimulate healing (Correct answer)
- Blocking nociceptor transmission at the dorsal horn
- Increasing intra-articular synovial fluid production
- Stretching Type I collagen fibers beyond their elastic limit
Correct answer: Creating localized controlled microtrauma to stimulate healing
IASTM instruments introduce controlled microtrauma that triggers an inflammatory healing cascade, recruiting fibroblasts to remodel scar and fascia.
