Real Time Ultrasound

A real-time ultrasound (RTUS) is a diagnostic imaging technique used by physiotherapists to assess and train muscle activation or deactivation. Unlike traditional ultrasound scans used for medical diagnoses, RTUS provides live, moving images of muscles, tendons, and other soft tissues, allowing both the physiotherapist and the patient to see how muscles are working in real-time.

RTUS is particularly useful for assessing deep core muscles, pelvic floor muscles, and other stabilizing muscles that are difficult to feel or activate correctly. It helps with:

• Identifying muscle imbalances, weaknesses and overactivity
• Providing visual feedback to improve muscle engagement and relaxation
• Guiding rehabilitation for conditions like low back pain, pelvic floor dysfunction, or post-surgical recovery
• Enhancing core stability and injury prevention

By using RTUS, physiotherapists can develop more targeted treatment plans, ensuring patients are correctly engaging the right muscles for recovery and long-term function.

The time it takes to receive ultrasound results in Australia can vary depending on the type of ultrasound, the urgency of the case, and the healthcare provider. However, here are general timeframes:

General Time Frames for Ultrasound Results:

Routine Ultrasound (e.g., pregnancy, abdominal, musculoskeletal scans): Results are typically available within 24–48 hours. The radiologist interprets the images and sends a report to your referring doctor.

Urgent or Emergency Ultrasound: Results can be available within a few hours, especially if done in a hospital or emergency setting. The radiologist may provide an immediate verbal report to the doctor if urgent action is required.

Specialist or Complex Ultrasounds (e.g., detailed organ scans, Doppler studies): These may take 2–5 days, depending on the complexity and the radiology provider’s workload.

Real-Time Ultrasound for Physiotherapy or Guided Treatment: If performed by a physiotherapist or specialist for assessment, feedback is usually immediate, as they interpret the scan in real time.

Real-Time Ultrasound (RTUS) is a non-invasive imaging technique that uses sound waves to create live images of soft tissues, organs, and muscles. In physiotherapy, RTUS is primarily used to assess muscle function, guide rehabilitation, and monitor treatment progress, rather than for traditional diagnostic purposes like detecting diseases.

However, it is highly effective in identifying musculoskeletal issues, movement dysfunctions, and certain soft tissue abnormalities.

1. Muscle Activation & Core Stability Assessments

• Pelvic floor dysfunction (e.g., incontinence, prolapse)
• Transverse abdominis activation (deep core muscle control)
• Diastasis recti (abdominal separation post-pregnancy)
• Chronic lower back pain (to assess deep stabilizing muscles like the multifidus)

2. Pelvic Health & Postnatal Recovery

• Pelvic floor muscle strength and function (for incontinence or pelvic organ prolapse)
• Bladder and bowel dysfunctions
• Postnatal pelvic floor and core recovery
• Monitoring abdominal muscle separation and its healing post-pregnancy

3. Musculoskeletal Conditions & Sports Injuries

• Muscle tears, strains, and ruptures (e.g., hamstring or calf tears)
• Tendon injuries (e.g., rotator cuff tendinopathy, Achilles tendinitis)
• Ligament sprains and tears (e.g., ankle sprains)
• Soft tissue inflammation (e.g., bursitis)
• Muscle imbalances or compensatory movement patterns

4. Joint & Soft Tissue Assessments

• Joint effusions (fluid buildup)
• Bursitis (e.g., shoulder or hip bursitis)
• Tendon pathologies (e.g., partial tears or tendinosis)
• Synovitis (joint inflammation)

5. Nerve & Vascular Issues

• Entrapment neuropathies (e.g., carpal tunnel syndrome)
• Nerve irritation or compression (e.g., sciatic nerve assessment)
• Vascular flow assessment (to rule out blood clots or assess circulation)

6. Post-Surgical Monitoring & Rehabilitation

• Assessing muscle recovery post-surgery (e.g., after rotator cuff or ACL repair)
• Monitoring scar tissue formation and soft tissue healing
• Evaluating tendon or ligament grafts post-reconstruction

7. Guided Interventions & Injections

• While typically done by radiologists or specialists, RTUS can also assist in:
• Guided cortisone injections
• Dry needling or acupuncture guidance
• Hydrodissection procedures for nerve entrapments

Limitations of Real-Time Ultrasound:

While RTUS is valuable for assessing soft tissues and muscle function, it is not designed to detect:

• Bone fractures
• Deep organ pathologies (e.g., liver, kidneys)
• Complex neurological conditions
• For these, other imaging like MRI, CT scans, or X-rays may be required.

Final Thoughts:

Real-Time Ultrasound is a valuable tool in physiotherapy for diagnosing muscle dysfunction, soft tissue injuries, and postnatal pelvic health issues. It allows physiotherapists to assess how muscles activate during movement and tailor rehabilitation programs accordingly.

By providing live feedback, RTUS helps patients visualize their muscle engagement and improve their technique during rehab, leading to faster, more effective recovery.

Real-Time Ultrasound (RTUS) is a non-invasive imaging technique that uses sound waves to provide live, dynamic images of muscles, tendons, ligaments, and soft tissues. In physiotherapy, RTUS is used as a biofeedback tool to assess and guide muscle activation, improve movement patterns, and support the rehabilitation process.

While commonly associated with diagnostic imaging in medical fields, in physiotherapy, real-time ultrasound focuses on functional assessment and rehabilitation, rather than diagnosing structural damage.

Key Ways Real-Time Ultrasound Supports Injury Rehabilitation:

1. Accurate Muscle Activation Assessment

RTUS allows physiotherapists to visualize how muscles contract in real time.

It helps assess whether key stabilizing muscles (like the deep core muscles or pelvic floor) are being engaged correctly.

Particularly useful for identifying weak or underactive muscles that may not be firing as they should during movement.

2. Biofeedback for Motor Control Retraining

Patients can see their muscles working on the screen as they perform movements, providing immediate feedback.

This helps patients learn how to correctly activate specific muscles, such as the transverse abdominis, pelvic floor, or multifidus.

Visual feedback enhances body awareness and helps correct faulty movement patterns that may lead to injury.

3. Pelvic Floor & Core Muscle Rehabilitation

RTUS is widely used in the rehabilitation of pelvic floor dysfunction, postnatal recovery, and conditions like urinary incontinence.

It helps assess pelvic floor contractions and guides patients in properly engaging deep core muscles.

In postnatal women, it helps track recovery from diastasis recti (abdominal separation) and guides safe core exercises.

4. Improved Diagnosis of Muscle Imbalances

RTUS helps physiotherapists identify muscle imbalances, asymmetries, or compensatory movements that may contribute to pain or dysfunction.

It’s particularly useful in assessing conditions like:

• Lower back pain (to see if deep core muscles are underactive)
• Hip and groin pain (to evaluate hip stabilizers)
• Shoulder injuries (to observe rotator cuff muscle activation)

5. Guided Rehabilitation for Soft Tissue Injuries

RTUS can visualize tendon injuries, muscle tears, and scar tissue formation to monitor healing progression.

It guides the physiotherapist in adjusting exercise intensity and load as the tissue heals, ensuring a safe return to activity.

6. Monitoring Progress During Rehabilitation

By periodically using RTUS throughout rehabilitation, physiotherapists can track improvements in muscle strength, endurance, and control.

This ensures that exercises are effective and allows for real-time adjustments to treatment plans.

Conditions Commonly Supported by Real-Time Ultrasound in Rehabilitation:

• Lower back pain (to assess deep core muscle activation)
• Pelvic floor dysfunction (e.g., incontinence, prolapse, postnatal recovery)
• Abdominal separation (diastasis recti) post-pregnancy
• Hip, groin, and pelvic pain
• Shoulder injuries (e.g., rotator cuff tendinopathy)
• Tendinopathies (e.g., Achilles tendinopathy, tennis elbow)
• Post-surgical rehabilitation (to monitor tissue healing and scar tissue formation)
• Benefits of Using Real-Time Ultrasound in Physiotherapy:
• Immediate visual feedback helps patients correct movement patterns.
• Non-invasive and pain-free, making it suitable for all ages.
• Improves muscle activation and motor control, reducing injury recurrence.
• Personalized rehabilitation programs based on individual muscle function.
• Assists in early identification of poor movement patterns that could lead to re-injury.

Real-Time Ultrasound is a valuable tool in injury rehabilitation, providing both the physiotherapist and the patient with a clear, visual understanding of muscle function and movement patterns. By offering real-time feedback, it empowers patients to engage the right muscles, correct faulty movement patterns, and accelerate recovery.

It is particularly beneficial for conditions involving deep core instability, pelvic floor dysfunction, or chronic pain, where visualizing muscle activation makes a significant difference in rehabilitation outcomes.

If you’re struggling with chronic pain, postnatal recovery, or recurring injuries, ask your physiotherapist whether real-time ultrasound could enhance your rehabilitation process.
