Prom Vs Arom: Who Wins In The Long Run?

Passive Range of Motion (PROM) is usually greater than Active Range of Motion (AROM). PROM is the range of movement achieved when an outside force causes a joint to move. It is the arc of motion produced by a therapist without assistance from the patient. On the other hand, AROM is the range of movement that can be achieved when opposing muscles contract and relax, resulting in joint movement. AROM is typically less than PROM as each joint has a small amount of available motion that is not under voluntary control.

PROM is greater than AROM because an outside force can provide overpressure

Passive Range of Motion (PROM) is the range of movement achieved when an outside force causes a joint to move. This is typically performed when a patient is unable or not permitted to move the body part actively. PROM is usually greater than Active Range of Motion (AROM) because an outside force can provide overpressure. This is particularly beneficial for bedridden or wheelchair-bound patients, helping them work towards potential recovery.

AROM is the range of movement that can be achieved when opposing muscles contract and relax, resulting in joint movement. It is the arc of motion a patient produces during a voluntary, unassisted muscle contraction. The way the patient performs this motion provides the clinician with information about willingness to move, ability to follow instructions, attention span, coordination, and muscle strength.

While PROM is usually greater than AROM, it is important to note that AROM is beneficial for overall health and improves mobility over time. AROM exercises strengthen muscles when they are actively engaged in movement. This can be achieved by holding movements or stretches for at least 30 seconds, building strength in the muscles needed for a particular movement.

In addition, AROM exercises provide stimulus for bone and joint integrity, increase circulation, and develop coordination and motor skills. PROM, on the other hand, is beneficial for maintaining elasticity of muscles and contractures, assisting circulation, and enhancing synovial movement.

In summary, PROM is typically greater than AROM because of the ability of an outside force to provide overpressure. However, both types of range of motion are important for different reasons and can be utilised to improve patient health and mobility.

PROM is greater than AROM due to the stretch of the tissues surrounding the joint

Passive Range of Motion (PROM) is the range of movement achieved when an outside force exclusively causes joint movement. This is typically performed when a patient is unable or not permitted to move the body part actively. PROM is usually greater than Active Range of Motion (AROM) due to the stretch of the tissues surrounding the joint and the reduced bulk of relaxed muscles compared to contracting muscles.

The way a patient performs AROM provides the clinician with information about the patient's willingness to move, their ability to follow instructions, attention span, coordination, and muscle strength. It can also identify movements that cause pain and the ability to perform functional activities. AROM is the range of movement that can be achieved when opposing muscles contract and relax, resulting in joint movement. This is performed independently by the patient, who voluntarily contracts, controls, and coordinates the movement. For example, AROM to flex the elbow requires the biceps to contract while the triceps relaxes.

PROM is the arc of motion produced by the therapist without assistance from the patient. PROM provides information about the integrity of the joint surfaces, extensibility of the joint capsule and surrounding ligaments, muscle, fascia, and skin. PROM is typically performed when a patient is unable or not permitted to move the body part actively, or when muscular activity is maximally reduced.

The stretch of the tissues surrounding the joint is a key factor in PROM being greater than AROM. This stretch allows for a greater range of motion, as the relaxed muscles are less bulky compared to contracting muscles. Additionally, the reduced muscle bulk during PROM can further contribute to the increased range of motion.

The stretch of the tissues surrounding the joint can be facilitated by heating the soft tissues to promote extensibility. Techniques such as static stretching, where a constant load is applied over time, can safely target collagen fibers that restrict motion while protecting from strain and tears. PNF stretching, which involves active movement, is also effective for increasing muscle length over time.

In summary, PROM is typically greater than AROM due to the stretch of the tissues surrounding the joint, allowing for a greater range of motion. This stretch is facilitated by the reduced bulk of relaxed muscles compared to contracting muscles. Therapeutic exercises such as PROM and stretching techniques can be utilized to maintain and promote elasticity, reduce posture impairment, and improve functional mobility.

PROM is greater than AROM because of the reduced bulk of relaxed muscles compared to contracting muscles

Passive Range of Motion (PROM) is greater than Active Range of Motion (AROM) due to the reduced bulk of relaxed muscles compared to contracting muscles. This is particularly important when a person is bedridden or wheelchair-bound, as a result of a stroke or accident, and is unable to move independently. PROM is also beneficial for those with a flaccid upper extremity due to a stroke. In such cases, PROM can be safely performed by a professional or caregiver, promoting joint and tissue integrity, and preventing contractures.

AROM, on the other hand, is the movement achieved when a person uses their muscles independently, without external assistance. This is particularly useful for strengthening muscles and improving overall health. However, AROM should be avoided in certain conditions, such as a broken or repaired extremity, where it could cause further damage.

The decision to use PROM or AROM depends on the specific condition and the potential risks of causing further damage. PROM is generally chosen when there is a need to increase the range of motion or prevent contractures, while AROM is selected when fluid movement and decreased edema are the primary goals.

In summary, PROM is advantageous when a person is unable to move independently or when there is a risk of causing damage by moving too far within the range of motion. On the other hand, AROM is beneficial for strengthening muscles and improving overall health through active engagement.

PROM is greater than AROM because of the slight elasticity of soft tissues

Passive Range of Motion (PROM) is the range of movement achieved when an outside force exclusively causes joint movement. It is the arc of motion produced by the therapist without assistance from the patient. PROM is typically greater than Active Range of Motion (AROM) due to the stretch of the tissues surrounding the joint and the reduced bulk of relaxed muscles compared to a contracting muscle.

The slight elasticity of soft tissues is one reason why PROM is greater than AROM. This is because the soft tissues can be stretched and manipulated to a greater degree than is possible with voluntary muscle contractions. The soft tissues can be stretched beyond their normal range, which can help to improve flexibility and mobility.

Another reason for the difference in ROM is the reduced bulk of relaxed muscles during PROM. When a muscle is in a relaxed state, it takes up less space and allows for a greater range of motion. In contrast, during AROM, the contracting muscle takes up more space and can limit the range of motion.

Additionally, PROM can be used to assess the integrity of the joint surfaces, extensibility of the joint capsule, and the surrounding ligaments, muscles, fascia, and skin. It is often used to assist in healing after injury or surgery, maintain awareness of movement, and determine limitations of motion and joint integrity.

AROM, on the other hand, is the range of movement that can be achieved when opposing muscles contract and relax, resulting in joint movement. It is the arc of motion a patient produces during a voluntary, unassisted muscle contraction. AROM is important for maintaining contractility of muscles, providing sensory feedback, and developing coordination and motor skills.

In summary, PROM is typically greater than AROM due to the slight elasticity of soft tissues, the reduced bulk of relaxed muscles, and the ability to manipulate and stretch the tissues beyond their normal range. PROM is often used to assist in healing and improve flexibility, while AROM helps to maintain muscle contractility and develop coordination.

PROM is greater than AROM when there is muscle weakness present

Range of motion (ROM) is a term used to describe how far a person can move or stretch a part of their body, such as a joint or a muscle. This can vary from person to person. For instance, some individuals can do the splits, while others cannot due to tighter joints and less flexible muscles.

Passive range of motion (PROM) is the extent to which a body part can move when an external force, such as a massage therapist, creates the movement. On the other hand, active range of motion (AROM) is the space in which an individual can move a body part using their muscles without external assistance.

In cases of muscle weakness, PROM is greater than AROM. This is because the patient is unable to actively move the affected body part and requires assistance to do so. PROM can be performed when a patient is unable or not permitted to move the body part actively. This can be due to muscle weakness, pain, or changes in muscle tone. PROM provides information about the integrity of the joint surfaces, extensibility of the joint capsule, and the condition of the surrounding ligaments, muscles, fascia, and skin.

For example, if a patient is recovering from a broken ankle, they will be unable to move their foot voluntarily for a period of time. A physical therapist can then apply pressure to the foot to move it just beyond what the patient can do on their own, thereby increasing the range of motion.

It is important to note that when performing PROM, the person assisting must be careful not to push beyond the patient's limit, as this may lead to a muscle tear or joint damage.
