Range-of-Motion Exercises: Types and Joint Movements
- Identify the three types of range-of-motion exercises and their specific benefits for joint mobility, circulation, and muscle maintenance.
- Demonstrate proper nurse aide safety practices, including body mechanics, joint support techniques, and recognizing signs of pain or resistance.
- Define anatomical joint movements and recognize specific exercises for the upper and lower extremities as directed by the care plan.
Understanding Range of Motion and Exercise Types
Range of motion (ROM) refers to the maximum amount of movement possible for a specific joint. For residents who have limited activity, staying in one position for long periods can lead to serious physical complications. Performing regular range-of-motion exercises helps maintain joint mobility and flexibility. In addition, moving the joints on a regular schedule helps stimulate blood circulation throughout the extremities and helps prevent contractures, which are permanent shortenings and stiffenings of muscles or tendons.
There are three primary types of range-of-motion exercises: active, active assistive, and passive. Active range-of-motion (AROM) exercises are performed independently by the resident without physical assistance. During active exercises, the nurse aide encourages and guides the resident according to the care plan and observes how the resident responds. Active range-of-motion exercises are especially valuable because they can help maintain muscle strength and reduce muscle atrophy, which is the decrease in size of muscle tissue.
Active assistive range-of-motion (AAROM) exercises are performed by the resident with partial assistance from a caregiver or an adaptive device. In contrast, passive range-of-motion (PROM) exercises are performed entirely by a caregiver without active effort from the resident. An everyday example of passive exercise is a caregiver gently lifting and supporting an immobile resident's arm through its normal movements. While passive movements maintain joint flexibility and stimulate blood circulation, passive exercises alone do not prevent muscle atrophy. The nurse aide assists with passive range-of-motion exercises only as directed by the resident's care plan and according to facility policy.
| Exercise Type | Who Performs the Movement | Effect on Muscle Atrophy |
|---|---|---|
| Active (AROM) | Performed independently by the resident without physical assistance | Maintains muscle strength and reduces muscle atrophy |
| Active Assistive (AAROM) | Performed by the resident with partial assistance from a caregiver or device | Provides active muscle use with caregiver or device support |
| Passive (PROM) | Performed entirely by a caregiver without resident active effort | Maintains joint mobility and circulation, but alone does not prevent atrophy |
Common mistakes
- Assuming passive ROM builds muscle: Believing passive range-of-motion exercises will prevent muscle atrophy. Passive movements maintain joint flexibility and stimulate blood circulation, but active exercises are needed to maintain muscle strength and reduce muscle atrophy.
- Gripping the joint directly: Holding onto the resident's joint directly rather than placing supporting hands gently above and below the joint being exercised.
- Forcing movement past resistance or pain: Pushing a limb beyond its natural stopping point or continuing repetitions after a resident winces or reports pain, which can cause muscle spasms or tissue injury.
- Leaving the bed elevated after care: Forgetting to return the bed to its lowest position and failing to place the call light within easy reach before leaving the resident's bedside.
Key points
- Range of motion (ROM) is the maximum movement possible for a joint; exercises maintain joint mobility, stimulate blood circulation, and help prevent contractures.
- Active ROM is performed independently and helps reduce muscle atrophy; passive ROM is performed entirely by a caregiver and alone does not prevent muscle atrophy.
- Always consult the care plan for specific joints, ROM types, and repetitions; if repetitions are missing, ask the nurse rather than guessing.
- Support limbs gently above and below the joint, move slowly and smoothly, and never force a joint past resistance or into the range of pain.
- Stop exercises immediately and report to the nurse if the resident complains of pain or shows nonverbal signs such as grimacing or wincing.
- Master joint movements, including flexion, extension, abduction, adduction, internal/external rotation, supination, pronation, dorsiflexion, and plantar flexion.
- Raise the bed for working height, return it to its lowest position with the call light in reach, report swelling or redness to the nurse, and document all completed care.
