6.5 Range of Motion, Positioning, and Contracture Prevention

Protecting Joints Through Daily Care

Range of motion (ROM) means moving a joint through its available movement, and there are three types the exam tests precisely. Active ROM (AROM) is performed by the resident independently, sometimes with verbal cues. Passive ROM (PROM) is performed entirely by the caregiver while the resident's joint is completely relaxed and the resident does no work. Active-assisted ROM (AAROM) is a combination: the resident moves the joint as much as they can and the caregiver supplies the remaining support. The nurse aide performs only the type, joints, repetitions, and frequency assigned by the care plan.

ROM also uses standard movement terms. Flexion decreases the angle of a joint (bending the elbow); extension increases it (straightening the elbow). Abduction moves a limb away from the body's midline; adduction moves it toward the midline. You do not need to design ROM, but recognizing these words helps you follow an assignment correctly.

ROM matters because unused joints and muscles stiffen. A resident who stays in one position may lose shoulder movement, hand opening, hip extension, knee motion, or ankle flexibility, which makes bathing, dressing, transfers, and walking harder. The goal is not athletic stretching — it is safe maintenance of comfort, circulation, and usable movement.

Contractures, Technique, and Positioning Devices

A contracture is a permanent or semi-permanent shortening of muscle, tendon, or other tissue that limits a joint. Contractures develop after stroke, immobility, neurologic disease, pain, poor positioning, or simple lack of use, and they can affect hands, elbows, shoulders, hips, knees, and ankles. Foot drop (the foot pointing downward from an unsupported ankle) is a classic preventable contracture. Prevention combines gentle movement, good body alignment, and ordered devices.

ROM and Positioning Safety

Technique rules are heavily tested: support the body part, move slowly and smoothly, avoid jerking, and never force a joint or push past the assigned range. If the resident resists, ask what is wrong — resistance may come from pain, fear, confusion, or fatigue — then stop and report rather than overpowering them. Watch for nonverbal pain signs like grimacing, clenched teeth, groaning, or guarding.

Common positioning devices include hand rolls (prevent clenched-hand contractures), footboards or foot splints (prevent foot drop), trochanter rolls (prevent external hip rotation), pillows for alignment, and heel protectors for pressure relief — all used only as the care plan directs.

Skin Checks and Building ROM Into Routine Care

Skin checks are essential because positioning devices create pressure. Braces, splints, shoes, oxygen tubing, wheelchair footrests, and bed supports can rub or compress tissue. Report redness, blisters, swelling, indentations, coolness, numbness, tingling, drainage, odor, or any complaint of pain. The aide must not add padding, permanently remove a prescribed device, or change a wearing schedule without nurse or therapy direction — those are clinical decisions.

ROM can be woven into ordinary care so it happens consistently:

• During bathing, the resident may raise the arms, open the hands, bend the knees, or turn the head within the plan.
• During dressing, encourage safe arm movement and gentle participation, dressing the affected side first.
• During meals, hand-to-mouth movement is itself active range of motion for the arm and hand.

These small, repeated movements help preserve ability without a separate exercise session. On exam questions, choose the answer that is gentle, planned, and observant: explain the task, provide privacy, support the limb, move only as assigned, stop for pain or resistance, and report changes. Avoid any option that forces motion, invents new exercises, ignores a skin problem, or continues simply because the routine must be finished. Comfort and safety always outrank completing every repetition.

A Simple Order of Operations for ROM

When a question describes performing range of motion, the correct steps usually follow a predictable order, and recognizing it helps you pick the best answer:

1. Prepare — wash hands, explain the activity, provide privacy, and position the resident comfortably.
2. Support — cradle the limb above and below the joint with your hands or forearm.
3. Move — exercise each joint slowly through the assigned motions (flexion/extension, abduction/adduction) to the point of slight resistance only.
4. Repeat — perform the assigned number of repetitions, usually starting at the head or shoulders and working down, doing each joint smoothly.
5. Observe and report — watch for pain, resistance, or swelling, then document what was done and the resident's tolerance.

Unless a joint is specifically excluded by the care plan (for example, a recently fractured or surgically repaired joint), the aide exercises the joints assigned and skips anything the plan restricts. A new or recent injury, a red or swollen joint, or sudden pain are reasons to stop and check with the nurse before continuing, never reasons to push harder.
