You’re in the ICU, and your patient with a C5 spinal cord injury is getting ready for their first sit on the edge of the bed. They have movement in their deltoids and biceps, but their hands are completely non-functional. This is the reality of life with quadriplegia, and understanding the nuances of this condition is essential for creating a safe, functional Plan of Care (POC).
What is Quadriplegia (Tetraplegia)?
Quadriplegia, also known as tetraplegia, is a neurological condition resulting from a spinal cord injury (SCI) to the cervical spine (C1-T1). This results in loss of motor and sensory function in all four extremities, as well as the trunk. The term tetraplegia (meaning “four” in Greek) is actually the preferred term by the American Spinal Injury Association (ASIA) to avoid confusion with “quad” (meaning four) and “plegia” (paralysis). The level of injury dictates the degree of functional impairment, with higher lesions (C1-C3) requiring ventilator support and lower lesions (C7-C8) allowing for more upper extremity control.
Why Quadriplegia Matters in Physical Therapy Practice
This is a life-altering diagnosis that impacts every single system. As a PT, you are a critical member of the interdisciplinary team, focusing on maximizing independence and preventing secondary complications. Your POC is not about “curing” the injury, but about functional retraining within the context of the patient’s new body. You’ll address respiratory function, bed mobility, transfers, wheelchair propulsion, and upper extremity strengthening to optimize their quality of life and discharge disposition.
What You’ll See in the Clinic
Clinical presentation varies wildly based on the level of injury. A patient with a C5 injury may have shoulder abduction and elbow flexion (via the biceps) but no wrist or hand function. A patient with a C7 injury may be able to extend their elbow and wrist, allowing for tenodesis (passive finger flexion when the wrist extends) to grasp objects. You will also see impaired trunk control, making sitting balance a primary focus.
“Day 3 post C6 SCI. Patient is alert and following commands. Motor: R/L deltoids 4/5, biceps 4/5, wrist extensors 2/5, triceps 1/5. Sensory intact to C5. Primary focus for today: sitting balance at edge of bed with support and initiating a mat program for upper extremity weight-bearing. Will instruct on tenodesis grasp technique.”
Common Pitfall & Pro Tip
⚠️ Pitfall: Focusing too heavily on the upper extremities and neglecting the respiratory system. High-level quadriplegia often impairs the intercostals and abdominals, leading to a weak cough and increased risk of pneumonia. Always prioritize vital capacity and secretion management.
💡 Pro Tip: When working on transfers, don’t just focus on the patient’s arms. Teach them to use their head and neck as a lever to shift their center of gravity. Cueing “Chin to chest to lift your hips” can be a game-changer for a patient with a C6 injury performing a sliding board transfer.
Memory Aid for Quadriplegia
Think “C-1 to T-1: All Four Under the Sun”. The “sun” represents the cervical spine, and everything below it (all four limbs) is affected. For functional levels, remember “C5: Elbow, C6: Wrist, C7: Elbow straight” — this helps you quickly predict what movements are available to build your POC around.
NPTE Connection
Expect to see questions that present a clinical scenario with specific myotome findings and ask you to identify the level of injury or the most appropriate functional goal or transfer technique for that level. Know your key muscles for C5, C6, C7, and C8.
Related Physical Therapy Concepts
Understanding quadriplegia requires a solid foundation in Spinal Cord Injury (SCI) Classification, including the ASIA Impairment Scale. It also directly relates to Autonomic Dysreflexia (a life-threatening emergency), Orthostatic Hypotension, and Pressure Injury Prevention, all of which are critical components of a comprehensive plan of care for this patient population.
Quick Reference
✓ Key levels: C5 (elbow flexion), C6 (wrist extension), C7 (elbow extension) ✓ Priority level: Critical – High risk for medical complications ✓ PT Interventions/Considerations: • Respiratory management: assisted cough, incentive spirometry • Bed mobility and transfer training (sliding board) • Strengthening of available innervated muscles • Wheelchair propulsion and seating/pressure relief • Patient and family education on skin checks and ROM
Bottom line: Your role with a patient with quadriplegia is to be their biggest advocate and most creative problem-solver, turning small movements into life-changing independence.
