9.2 Range of Motion (ROM) Exercises & Positioning
Key Takeaways
- Range of motion (ROM) exercises prevent joint contractures, muscle atrophy, and circulatory stasis, categorized into Active ROM (AROM), Active-Assisted ROM (AAROM), and Passive ROM (PROM).
- During Passive ROM (PROM), the nursing assistant must provide dual-joint support proximally and distally (above and below the joint), execute slow, gentle movements for 3 to 5 repetitions per joint, and stop immediately if resistance or pain is encountered.
- Key anatomical joint motions include flexion/extension, abduction/adduction, pronation/supination, dorsiflexion/plantar flexion, internal/external rotation, and inversion/eversion.
- Contracture prevention devices such as hand rolls, trochanter rolls (preventing external hip rotation), footboards, and ankle-foot orthoses (AFOs) prevent foot drop and permanent muscular shortening.
- Bed positioning requires strict Q2H turning using supportive pillows: Supine, Fowler's (45–60°), Semi-Fowler's (30–45°), High Fowler's (60–90° for eating/dyspnea), Lateral (30° tilt with 4 pillows), Sims' (left semi-prone for enemas), and Prone.
Range of Motion (ROM) Exercises & Positioning
Immobility poses severe physiological hazards to elderly and bedridden residents. Within days of complete bed rest, muscles lose up to 12% of their strength per week, tendons and ligaments shorten, and joints develop irreversible fibrotic stiffness known as contractures. Certified Nursing Assistants (CNAs) maintain musculoskeletal integrity, stimulate joint lubrication, and prevent permanent deformities by conducting systematic Range of Motion (ROM) exercises and maintaining rigorous body positioning schedules.
1. Range of Motion Modalities & Physiological Benefits
Range of motion is the complete extent of movement of which a healthy joint is normally capable. Depending on the resident's cognitive status, muscular strength, and medical condition, ROM is classified into three modalities:
+-----------------------------------------------------------------------------+
| RANGE OF MOTION (ROM) SPECTRUM |
| |
| ACTIVE ROM (AROM) ACTIVE-ASSISTED ROM (AAROM) PASSIVE ROM (PROM) |
| - Performed completely - Resident moves joint with - CNA moves joint |
| by the resident. partial CNA assistance. entirely without |
| - No physical assistance - Used when muscles are weak resident effort. |
| from caregiver. or easily fatigued. - Used in coma, |
| - Builds muscle strength - Maintains joint movement paralysis, or |
| and endurance. with guided support. severe weakness. |
+-----------------------------------------------------------------------------+
Systemic Benefits of Regular ROM Exercises:
- Musculoskeletal: Prevents muscle atrophy, maintains tendon elasticity, and prevents permanent contractures.
- Joint Health: Stimulates synovial fluid circulation, nourishing articular cartilage and preventing ankylosis (joint fusion).
- Cardiovascular: Promotes venous blood return from extremities toward the heart, reducing the risk of deep vein thrombosis (DVT) and peripheral edema.
- Gastrointestinal & Renal: Stimulates peristalsis, preventing constipation and reducing urinary stasis and kidney stone formation.
- Psychological: Improves resident body awareness, comfort, and sleep quality while reducing chronic joint pain.
2. Principles of Passive ROM (PROM) Execution
In Arizona D&SDT-Headmaster clinical skills evaluations, PROM is a frequently tested skill (specifically PROM to one shoulder and PROM to one knee and ankle). CNAs must master the strict safety and mechanical principles governing PROM.
+-----------------------------------------------------------------------------+
| HEADMASTER PROM CLINICAL CHECKPOINTS |
| |
| [PREPARATION] --------> Wash hands, introduce self, verify resident ID, |
| provide privacy, explain procedure. |
| [BED ERGONOMICS] -----> Raise bed to comfortable working waist height; |
| ensure bed brakes are locked. |
| [EXPOSURE & DRAPING] -> Uncover ONLY the limb being exercised to preserve |
| warmth and personal dignity. |
| [JOINT SUPPORT] ------> Support limb PROXIMALLY & DISTALLY (above & below |
| the joint) using cupped hands. |
| [MOVEMENT QUALITY] ---> Move joint SLOWLY, SMOOTHLY, and GENTLY. |
| [REPETITION COUNT] ---> Repeat each movement 3 TO 5 TIMES (or per care |
| plan). |
| [PAIN & RESISTANCE] --> STOP IMMEDIATELY if resident reports pain or if |
| physical resistance/spasm is felt. |
| [COMPLETION] ---------> Lower bed to lowest position, place call light in |
| reach, perform hand hygiene, report/document. |
+-----------------------------------------------------------------------------+
Core Rules of PROM Delivery:
- Dual Joint Support (Above and Below): Never grasp a joint directly or pull on fingers/toes. Always place one hand under the extremity proximally (above the joint) and the other hand distally (below the joint) to cradle and stabilize the limb securely. For example, during shoulder flexion, support the resident's arm at the elbow and wrist.
- Never Force Movement: Move the joint only to the point of comfortable resistance. If the joint feels tight or if the resident flinches, winces, or verbalizes pain, stop the exercise immediately, return the limb to a neutral resting position, and notify the charge nurse.
- Continuous Communication: Maintain eye contact and observe the resident's facial expressions throughout the procedure for non-verbal indicators of discomfort (e.g., furrowed brow, grimacing, clenching teeth, holding breath).
- Standard Repetitions: Execute each distinct anatomical movement 3 to 5 times smoothly before proceeding to the next movement or joint.
3. Anatomical Planes, Joint Actions & Terminology
CNAs must understand precise anatomical movement terms to follow care plan directives and document care accurately.
+-----------------------------------------------------------------------------+
| ANATOMICAL JOINT MOVEMENTS |
| |
| FLEXION: Bending joint (decreases angle) EXTENSION: Straightening joint |
| ABDUCTION: Moving AWAY from midline ADDUCTION: Moving TOWARD midline|
| PRONATION: Turning palm DOWNWARD SUPINATION: Turning palm UPWARD |
| DORSIFLEXION: Bending foot UP toward shin PLANTAR FLEXION: Pointing toes |
| INTERNAL ROTATION: Turning INWARD EXTERNAL ROTATION: Turning OUT |
| INVERSION: Turning sole of foot INWARD EVERSION: Turning sole OUTWARD |
+-----------------------------------------------------------------------------+
| Joint / Body Region | Movement | Anatomical Description | Clinical Example in Care |
|---|---|---|---|
| Neck / Cervical Spine | Flexion / Extension | Bending head forward toward chest / returning to upright | Checking range during morning grooming |
| Lateral Flexion | Tilting head sideways toward shoulder | Relieving neck muscle stiffness | |
| Rotation | Turning head from side to side (looking left/right) | Encouraging visual scanning in room | |
| Shoulder (Ball & Socket) | Flexion / Extension | Raising straight arm overhead / lowering arm to side | PROM Shoulder skill test in Headmaster |
| Abduction / Adduction | Moving straight arm away from side / returning to side | Washing axilla / dressing upper body | |
| Internal / External Rotation | Rotating arm inward toward body / outward away from body | Putting arm into a jacket sleeve | |
| Elbow (Hinge) | Flexion / Extension | Bending elbow to touch hand to shoulder / straightening | Washing forearm and antecubital fossa |
| Forearm | Pronation / Supination | Turning palm downward / turning palm upward ("soup bowl") | Placing hand on armrest or dining table |
| Wrist | Flexion / Extension | Bending hand downward at wrist / bending hand backward | Applying wrist splints |
| Radial / Ulnar Deviation | Tilting hand toward thumb (radial) / toward pinky (ulnar) | Maintaining hand flexibility | |
| Fingers & Thumb | Flexion / Extension | Clenching fingers into a fist / opening hand flat | Hand hygiene / cleaning palm crease |
| Abduction / Adduction | Spreading fingers apart / bringing fingers together | Washing between fingers | |
| Opposition | Touching thumb tip to the tip of each finger | Retraining fine motor pincher grasp | |
| Hip (Ball & Socket) | Flexion / Extension | Raising leg upward toward chest / lowering leg flat | Perineal care and repositioning |
| Abduction / Adduction | Moving leg outward away from midline / moving leg inward | Placing pillows between knees | |
| Internal / External Rotation | Rolling thigh inward toward midline / rolling thigh outward | Trochanter roll placement | |
| Knee (Hinge) | Flexion / Extension | Bending knee toward buttocks / straightening leg flat | PROM Knee/Ankle skill in Headmaster |
| Ankle (Hinge) | Dorsiflexion | Bending foot upward toward the shin (toes point up) | Crucial for preventing foot drop |
| Plantar Flexion | Pointing toes downward away from shin ("planting gas pedal") | Assessing calf tendon tightness | |
| Inversion / Eversion | Turning sole of foot inward / turning sole outward | Inspecting ankles for skin breakdown |
4. Contracture, Foot Drop & Deformity Prevention Devices
A contracture is the permanent shortening, tightening, and hardening of a muscle, tendon, or ligament, resulting in a locked, deformed joint that cannot be straightened. A severe contracture of the hand freezes fingers into a clenched fist (digging nails into the palm), while hip and knee contractures lock legs in a fetal position, making hygiene and dressing nearly impossible.
+-----------------------------------------------------------------------------+
| CONTRACTURE & DEFORMITY PREVENTION DEVICES |
| |
| [TROCHANTER ROLL] ------> Placed along the outer thigh/hip from iliac |
| crest to mid-thigh to prevent external rotation |
| of the hip (keeps legs & knees pointing up). |
| [HAND ROLL / CONE] -----> Placed in palm to keep fingers slightly flexed |
| in a natural functional C-shape grasp. |
| [FOOTBOARD / AFO] ------> Keeps ankle at 90° dorsiflexion, preventing |
| Achilles tendon shortening & FOOT DROP. |
| [ABDUCTOR PILLOW] ------> Triangular wedge placed between legs following |
| total hip replacement to prevent adduction. |
+-----------------------------------------------------------------------------+
Key Positioning & Prevention Devices:
- Trochanter Rolls: Made of a rolled bath blanket, towel, or foam cylinder. It is placed alongside the resident's greater trochanter and lateral thigh (from above the hip down to the mid-thigh) when in the supine position. Purpose: Prevents the hip and leg from rotating outward (external rotation), maintaining proper anatomical alignment of the femur.
- Hand Rolls & Palm Cones: Cloth or foam cylinders placed in the palm of a resident with spasticity or weakness. Purpose: Keeps the hand in a functional resting grasp (fingers slightly curved, thumb opposed), preventing fingers from curling tightly into the palm, which causes fungal infections, foul odor, and skin breakdown.
- Footboards, Multipodus Boots & Ankle-Foot Orthoses (AFOs): Rigid padded boards or plastic splints placed at the foot of the bed or worn on the lower leg. Purpose: Prevents foot drop (equinus deformity), a condition where the calf muscle shortens and the foot drops permanently into plantar flexion, making standing and walking impossible.
- Abductor Pillows (Hip Wedges): Firm triangular foam wedges strapped between the resident's thighs following total hip arthroplasty (hip replacement). Purpose: Keeps hips abducted, preventing the surgical leg from crossing the midline (adduction) and dislocating the new prosthetic joint.
- Bed Cradles: Metal frames placed over the lower bed frame beneath the top linens. Purpose: Keeps heavy blankets and sheets from resting directly on the resident's feet and toes, preventing pressure sores on toes and relieving pressure that worsens foot drop.
5. Therapeutic Bed Positions & Body Alignment Schedules
Bedridden residents must be repositioned at least every two hours (Q2H) around the clock. Proper positioning maintains anatomical body alignment, relieves pressure over bony prominences, and prevents contractures.
+-----------------------------------------------------------------------------+
| THERAPEUTIC BED POSITIONS |
| |
| SUPINE: Flat on back (Head & shoulders supported by small pillow) |
| FOWLER'S: Head of bed raised 45° to 60° (Comfort, visits, grooming) |
| SEMI-FOWLER'S: Head of bed raised 30° to 45° (Tube feeding, reduces shear)|
| HIGH FOWLER'S: Head of bed raised 60° to 90° (Meals, swallowing, dyspnea) |
| 30° LATERAL (Side-Lying): Tilted 30° with 4 supportive pillows |
| SIMS' (Semi-Prone): Left side-lying, upper leg flexed (Enemas & suppos.) |
| PRONE: Flat on abdomen, head turned to side (Rarely used in elderly) |
| TRENDELENBURG: Bed flat, foot of bed RAISED, head LOWERED (Shock/surgery) |
| REVERSE TRENDELENBURG: Bed flat, head RAISED, foot LOWERED (Reflux/ICP) |
+-----------------------------------------------------------------------------+
Clinical Positions & Key Indications:
- Fowler's Position (45° to 60°): Head of the bed is elevated to a moderate angle. Promotes chest expansion, cardiac relaxation, and comfortable social interaction.
- Semi-Fowler's Position (30° to 45°): Head of the bed is elevated slightly. Ideal for residents receiving continuous enteral tube feedings (prevents aspiration) and reduces shear forces on the sacrum.
- High Fowler's Position (60° to 90°): Head of the bed is upright near 90 degrees. Mandatory during all oral meals, drinking, oral medication administration, and severe respiratory distress (orthopnea/dyspnea) to prevent choking and aspiration pneumonia.
- 30-Degree Lateral (Side-Lying) Position: The gold-standard pressure-relieving lateral position. The resident is turned onto their side and angled back at a 30-degree tilt, preventing direct pressure on the fragile greater trochanter of the hip and sacrum.
- The 4-Pillow Support Rule:
- Pillow 1: Under the head and neck.
- Pillow 2: Folded lengthwise and tucked firmly behind the back to maintain the 30-degree tilt.
- Pillow 3: Placed between the knees, thighs, and ankles to prevent bone-on-bone friction and keep hips aligned.
- Pillow 4: Placed under the upper arm and wrist to support the shoulder and promote full chest expansion.
- The 4-Pillow Support Rule:
- Sims' (Semi-Prone) Position: The resident lies on their left side with the lower arm behind the body and the upper right leg sharply flexed at the hip and knee. Primary Indication: Administering cleansing enemas, rectal suppositories, and rectal temperature measurements.
- Prone Position: The resident lies flat on their abdomen with head turned to one side. Requires nurse assessment; contraindicated in residents with respiratory disease, tracheostomies, abdominal incisions, or spinal arthritis.
- Trendelenburg Position: The entire bed frame is tilted with the head lower than the feet (requires a physician's order; used for acute hypotensive shock or pelvic surgery). Reverse Trendelenburg tilts the entire bed frame with the head higher than the feet (used for severe gastroesophageal reflux or intracranial pressure).
A CNA is performing passive range of motion (PROM) on a bedridden resident's knee and ankle. Which practice complies with official clinical safety standards?
A nursing assistant observes a rolled bath blanket placed along the outer aspect of a supine resident's hip and lateral thigh extending to mid-thigh. What is the clinical purpose of this trochanter roll?
A CNA is positioning a resident in a 30-degree lateral (side-lying) position for pressure injury prevention. How should pillows be placed to maintain proper alignment and eliminate bony friction?
