Range of Motion (ROM) & Mobility Support

Range of Motion (ROM) & Mobility Support

Maintaining physical mobility and joint flexibility is essential to the health, dignity, and independence of long-term care residents. When illness, surgery, or progressive neurological conditions restrict a resident's movement, nursing assistants (CNAs) provide restorative care interventions—specifically Range of Motion (ROM) exercises—to protect musculoskeletal integrity and prevent devastating complications of immobility.

Introduction to Restorative Care & Rehabilitation

While the terms rehabilitation and restorative care are often used together, they represent distinct components of long-term care:

• Rehabilitation Care: Program prescribed by a physician and directed by licensed physical therapists (PT), occupational therapists (OT), or speech-language pathologists (SLP). Its primary objective is to assist the resident in regaining lost skills or restoring functional abilities following an acute event, such as a stroke, hip fracture, or major surgery.
• Restorative Nursing Care: Program led by nursing staff—primarily nursing assistants under the supervision of a licensed nurse—to help residents maintain the functional abilities achieved during therapy, prevent physical regression, promote self-care, and integrate mobility into daily activities.

Restorative care is an ongoing daily commitment. Even when formal physical therapy ends, restorative ROM exercises ensure that gains in joint mobility and muscle strength are preserved over time.

Types of Range of Motion (ROM) Exercises

Range of Motion refers to the maximum limit of movement that a healthy joint can perform in a given direction. Depending on the resident's physical capabilities and medical status, ROM exercises are classified into three primary categories:

1. Passive Range of Motion (PROM)

• Definition: Exercises performed entirely by the nursing assistant without any active muscle contraction or exertion from the resident.
• Indication: Prescribed for residents who are paralyzed, comatose, severely debilitated, or uncooperative due to advanced dementia.
• CNA Role: The CNA moves each joint through its natural range of movement while supporting the limb carefully.

2. Active-Assisted Range of Motion (AAROM)

• Definition: Exercises performed jointly by the resident and the nursing assistant.
• Indication: Prescribed for residents who have partial muscle strength or partial motor control but lack the endurance or power to complete the full arc of movement independently.
• CNA Role: The resident initiates the movement, and the CNA provides gentle guidance, support, or light lifting to help the joint complete its full motion safely.

3. Active Range of Motion (AROM)

• Definition: Exercises performed completely by the resident without physical assistance from healthcare staff.
• Indication: Prescribed for residents who possess sufficient muscle strength, coordination, and mental acuity to move their limbs through full motion.
• CNA Role: The CNA supervises, provides clear verbal instructions, encourages the resident, monitors for fatigue or pain, and documents completion.

Anatomical Movements and Joint Terminology

To perform ROM exercises correctly and document procedures accurately, nursing assistants must understand key anatomical movements and joint terminology:

• Flexion: Bending a joint or body part, decreasing the angle between two connected bones (e.g., bending the elbow or flexing the knee).
• Extension: Straightening a joint or body part, increasing the angle between two connected bones (e.g., straightening a bent arm or leg).
• Hyperextension: Excessive extension or straightening of a joint beyond its normal anatomical position (e.g., bending the neck or wrist backward).
• Abduction: Moving an extremity or body part away from the midline of the body (e.g., raising the arm straight out to the side).
• Adduction: Moving an extremity or body part toward the midline of the body (e.g., bringing an outstretched arm back to the side of the body).
• Rotation: Turning a joint or body part around its central axis (e.g., turning the head from side to side, or rotating the shoulder/hip inward and outward).
• Pronation: Turning a body part downward (e.g., turning the palm of the hand facing down toward the bed or floor).
• Supination: Turning a body part upward (e.g., turning the palm of the hand facing up toward the ceiling).
• Dorsiflexion: Bending the foot backward at the ankle joint so the toes point upward toward the shin.
• Plantar Flexion: Bending the foot downward at the ankle joint so the toes point downward toward the ground (similar to pressing down on an automobile gas pedal).
• Opposition: Touching the tip of the thumb to the tip of each finger on the same hand (essential for fine motor grasp and holding objects).

CNA Clinical Rules & Safety Protocols for ROM

When carrying out Passive Range of Motion (PROM) or assisting with AROM, nursing assistants must strictly adhere to the following safety protocols:

1. Care Plan Verification: Review the resident's care plan before starting. Identify specific joint restrictions, post-surgical limitations (such as hip replacement precautions prohibiting hip adduction past midline), or special therapist instructions.
2. Preparation & Privacy: Explain the procedure to the resident prior to physical contact. Pull privacy curtains and drape the resident with a bath blanket, exposing only the specific extremity currently being exercised.
3. Body Mechanics: Adjust the bed to a comfortable working height (at the CNA's waist/hip level) to prevent back strain. Lower the bed rails on the side where you are working.
4. Proper Joint Support: Always support the extremity both above and below the joint being exercised. For example, when performing ROM on the wrist, support the forearm above the wrist with one hand and hold the resident's hand below the wrist with your other hand. Never hold a joint directly by the joint space or pull forcefully on fingers or toes.
5. Smooth, Slow Rhythm: Perform movements slowly, smoothly, and gently. Avoid rapid, jerky, or force-driven motions.
6. STOP AT POINT OF RESISTANCE OR PAIN (CRITICAL EXAM RULE): Move each joint only to the point of slight natural resistance or until the resident reports discomfort. NEVER FORCE A JOINT BEYOND ITS PAIN-FREE RANGE. If the resident winces, grimaces, tightens muscles, or verbalizes pain, stop immediately, return the limb to a neutral resting position, and notify the charge nurse.
7. Repetitions & Sequence: Standard care plan protocols require repeating each motion 3 to 5 times (or as ordered), performing the routine once or twice daily. Work systematically, moving from head to toe (neck, shoulder, elbow, wrist, fingers, hip, knee, ankle, toes) or as directed by the care plan.
8. Post-Care Duties: Lower the bed to its lowest position, lock bed wheels, place the call light within easy reach, perform hand hygiene, and report any joint redness, warmth, swelling, or resident complaints of pain to the nurse.
