MSK Ultrasound in Physical Therapy: Building Diagnostic Trust and Patient Buy-In
When most of us walk into a physical therapy clinic, our priority is simple: we want to know what is actually happening beneath the surface and how to fix it. But traditionally, rehabilitation clinicians haven’t had all the tools to provide real time feedback.
Dr. Christopher “CJ” Miller, PT, DPT, of Frontline Function, is challenging that limitation across orthopedic, primary care, and urgent care settings by placing musculoskeletal point-of-care ultrasound (MSK POCUS) at the center of his clinical evaluations. Instead of stepping in to issue corrective exercises for an injury diagnosed elsewhere, he now evaluates patients using ultrasound in addition to his physical exam.
Beyond direct patient care, Dr. Miller is dedicated to clinical education. His primary objective is to teach clinicians how to confidently integrate MSK ultrasound into day-to-day practice—bridging the gap between initial assessment, diagnostic precision, and effective rehabilitation pathways.
We recently interviewed CJ about his use of Clarius ultrasound in his practice. Watch the 3-minute video to learn more. Read on for highlights from our discussion.
Validating the Clinical Exam to Unlock Patient Adherence
According to CJ, integrating MSK ultrasound into clinical practice elevates the therapist’s role from carrying out third-party directives to evaluating soft-tissue integrity at the bedside. When direct visualization confirms physical exam findings, patient confidence shifts immediately.
The addition of ultrasound puts more weight in our ability to perform a really accurate clinical exam. If they can trust that you evaluate what’s happening really well, they’ll trust that you can get it better. ‘I’ve seen this tissue. You know what you’re talking about. Now I’m going to go ahead and fulfill this plan of care.'”
Seeing anatomy in real time replaces diagnostic ambiguity with therapeutic buy-in. When patients see the affected tissue side-by-side with healthy structures on screen, compliance moves from passive instruction to active participation in recovery.
Real-Time Validation: How Bedside Imaging Changes the Patient Experience
The clinical impact of point-of-care ultrasound is felt most clearly by the patient on the table.
For example, a year after undergoing surgery to repair a ruptured left Achilles tendon, CJ’s patient Mike Lampkin began experiencing discomfort and pain in his opposite, uninjured right ankle. Concerned about the risk of another prolonged recovery, Lampkin came in looking for clarity rather than guesswork. By performing an immediate, side-by-side ultrasound exam, Dr. Miller was able to assess tendon thickness, evaluate suspected inflammation, and compare both sides in real time.
Patient Video Interview: Mike Lampkin on Real-Time Ultrasound in Physical Therapy
As Lampkin shares in this 2-minute video, having objective imaging integrated seamlessly into a regular PT visit transformed the appointment into a transparent, collaborative evaluation that replaces anxiety with a clear, confident path forward.
It’s great to have that instant feedback and be able to have the comparison of the two tendons on the left and the right,” says Mike. It made me more confident as far as my rehab goes, and be able to have a clear path forward and not have a guessing game of what exactly is going on.”
Clarius Wireless Ultrasound: High-Definition MSK Imaging Built for Physical Therapy Practices
Clarius handheld wireless ultrasound machines deliver the resolution of conventional cart-based units in a completely untethered format engineered for daily mobility and affordability. Featuring high-frequency linear arrays optimized for musculoskeletal imaging, Clarius scanners pair wirelessly with standard iOS and Android devices, allowing clinicians to navigate smoothly between urgent care bays and rehabilitation treatment rooms. With high-definition dynamic imaging, intuitive split-screen comparisons, and intelligent, automated workflow tools, Clarius gives physical therapists reliable tissue visualization at the bedside without slowing clinical tempo.
Portability That Keeps Physical Therapists Mobile
Bulky ultrasound systems often create spatial bottlenecks in fast-moving clinics. Untethered, pocket-sized imaging eliminates those obstacles entirely explains CJ.
I think MSK ultrasound is expanding in physical therapy for a few reasons. First and foremost, I think your patients want to know what’s happening. The technology has gotten much more affordable and much smaller. So, these Clarius handheld units are wireless. If I’m going to see a patient up in our urgent care, I can have a bottle of gel in one pocket, an ultrasound probe in the other, and carrying an iPad, and I could be mobile, and I can get around a patient in a room no matter what room they’re in. I think it’s just become a lot more accessible while maintaining a high-quality image.”

Traditional facial thread lifting relies on surface lines drawn over unseen tissue layers, leaving practitioners to navigate complex facial anatomy entirely by touch. For aesthetic plastic surgeon Dr. Ahmed Abdelaziz, integrating high-resolution ultrasound after ten years of performing traditional thread was transformational. At his clinic, point-of-care ultrasound has replaced tactile guesswork with real-time visualization beneath the skin surface.
It ensures precise placement in the subcutaneous plane, maps unpredictable vasculature, and verifies vectors during scanning.
People are not anatomy books,” explains Dr. Abdelaziz during arecent Clarius webinar. “There is a lot of variation. And seeing and understanding this, using ultrasound, is really going to change how you approach this procedure.”
Watch this one-hour webinar to learn his techniques for using high-resolution point-of-care ultrasound (POCUS) to map individual vascular pathways, verify tissue layers in real time, and manage complications with precision. Stream the recording at your convenience to see live scanning, layer-by-layer dissection, and clinical case demonstrations: Ultrasound for Facial Aesthetics: Safety in Thread Lifting.
Read on for tips on proper thread depth, vascular safety maps and biofilm risks, and the Q&A with Dr. Abdelaziz.
What Is the Correct Anatomical Depth for Facial Thread Lifting?
For suspension and barbed threads (including PDO, PLLA, and PCL), the targeted placement plane is strictly the superficial subcutaneous fatty layer.
Placing threads too deeply into facial musculature or deep fascia limits mechanical tissue mobility and risks motor nerve or vascular injury; placing them too superficially within the intradermal space leads to visible extrusion, puckering, and skin dimpling.
The 5-Layer Facial Construct: Evaluate every vector across five discrete layers: skin/dermis, superficial subcutaneous fat, the superficial musculoaponeurotic system (SMAS)/facial muscles, deep fat pockets, and the periosteum.
Identifying the SMAS on Ultrasound: On high-resolution ultrasound, the SMAS appears as a distinct hyperechoic (bright whitish) linear band separating the hypoechoic fat globules of the superficial subcutaneous tissue from the deeper structures.
Avoid Deeper Anatomy:“You don’t want to lift the muscle,” warns Dr. Abdelaziz. “You don’t want to go through the muscle. You don’t want to lift the fascia, because at the end of the day, you can’t. The only way that you lift the skin is by going under the skin in the subcutaneous layer.”
Targeting Fixation Ligaments: Anchoring threads requires stable retaining structures. Ultrasound visualizes deep anchors—such as the zygomatic cutaneous ligament—allowing practitioners to fix threads securely rather than relying on mobile soft tissue alone.
Dynamic Cannula Tracking and Thread Trajectory Guidance
Ultrasound replaces blind tactile feel by tracking the needle, cannula, and thread continuously throughout insertion, trajectory adjustments, and post-deployment verification.
Visualize the Cannula Tip Dynamically: Use in-plane imaging (long axis) to display the entire cannula shaft and thread deployment, or out-of-plane imaging (short axis) to track cross-sections of the tip.
It doesn’t matter where your cannula is as long as you see the tip of the cannula. Because this is basically where you are heading and where your product comes out,” explains Dr. Abdelaziz.
Adjust the Transducer, Not the Instrument: Keep your cannula hand steady and maneuver the ultrasound probe perpendicular to the tissue plane to bring reflective structures into view. Levering or manipulating the cannula blindly inside the tissue causes unnecessary trauma.
Identify Acoustic Signatures of Threads: Barbed, cogged, and molded threads—whether composed of polydioxanone (PDO) or poly-L-lactic acid (PLLA)—produce distinct hyperechoic linear reflectors or double-laminar acoustic signals within the subcutaneous tissue.
Post-Placement Layer Verification: Scan the completed vector immediately after deployment to confirm that threads remain above the SMAS and clear of deep fat pockets. This post-procedure confirmation lets you “have a nice sleep after the procedure and you’re sure that everything was done at the right place,” Dr. Abdelaziz says.
Facial Vascular Anatomy: Preventing Hematomas and Vascular Compromise
Relying on standard textbook landmarks creates a false sense of security. A 2025 systematic review and meta-analysis of ten Doppler ultrasound studies revealed that only 46.2% of facial arteries follow the textbook path medial to the nasolabial fold. Ultrasound vascular mapping identifies arterial depth and anatomical variations along common thread vectors:
Temporal Region: Distinguish the superficial temporal artery embedded in the temporoparietal fascia from the deep temporal arteries situated within the temporalis muscle.
Lateral Cheek & Midface: Locate the infraorbital artery emerging from its foramen, and map the transverse facial and main facial arteries before selecting entry points.
Jawline & Mandibular Border: Trace the facial artery crossing the inferior border of the mandible, keeping vectors superficial to the platysma, submental vessels, and parotid gland.
Entry Point Pre-Scanning: Scan planned trocar and cannula entry points using Color Doppler under light probe pressure to prevent immediate vessel puncture and expansive hematomas.
Managing Thread Lift Complications: Infection, Biofilms, and Extraction
When adverse events develop, ultrasound provides immediate differential diagnosis and enables scar-free, ultrasound-guided foreign body retrieval.
The Filler-Biofilm Interaction: Placing threads through preexisting hyaluronic acid or permanent filler pockets can introduce bacteria into dormant foreign material. Similarly, injecting filler years after a thread procedure can disrupt an established subclinical biofilm.
If the threads had biofilm around it, and then after a year or two, sometimes patients got injected with fillers going through the biofilm… that filler created that infection process,” explains Dr. Abdelaziz.
Edema vs. Abscess Identification: Ultrasound differentiates normal postoperative edema (diffuse tissue swelling) from organized fluid collections, micro-abscesses, and hypervascular inflammatory capsules surrounding displaced sutures.
Minimally Invasive Thread Removal: Rather than performing open surgical incisions to find retracted or infected threads, clinicians can use ultrasound guidance to direct a sterile, blunt crochet hook directly into the fluid collection, engage the suture barbs, and retrieve the foreign body through a tiny puncture site.
Complication Case Video Demonstration: Ultrasound-Guided Thread Removal
The patient in this video has threads and HA filler. See how Dr. Abdelaziz uses ultrasound to locate the threads and guides their removal during this detailed 7-minute video.
Watch Dr. detail clinical infection cases and live ultrasound-guided thread removals in the full on-demand webinar.
Pre-Procedure Thread Lifting Checklist
Map Layers: Confirm the 5-layer construct and delineate the SMAS before needle entry.
Trace Vessels: Use Color Doppler with light probe contact to map regional arteries and check planned entry sites.
Check for Fillers: Identify preexisting hyaluronic acid or permanent fillers to avoid puncturing dormant biofilms.
Track the Cannula Tip: Maintain dynamic in-plane or out-of-plane visualization throughout instrument advancement.
Post-Placement Scan: Verify that all threads are seated uniformly within the subcutaneous layer along the entire vector.
Audience Q&A: Practical Advice from Dr. Ahmed Abdelaziz
Q: How do you maintain a sterile field when using ultrasound during thread lifting?
Dr. Abdelaziz:“You have multiple options for that… In the OR, it’s very easy to use the sterile camera cover… wrap it and use sterile gel on top of the skin. There is another way if you have sterile elastic covers… use a little bit of gel inside and then put it on top of your device.”
Q: Do PLA/PLLA threads cause more complications than PDO threads?
Dr. Abdelaziz:“Actually, no. Complications are complications… PDO should by theory dissolve faster, but in my practice, I saw complications from PDOs as much as I saw from PLA. PDOs are more common because they are cheaper and there are more on the market… You can have complications from any device you implant in tissues if you’re not sterile or not using the right disinfection.”
Q: What specific hook do you use to remove infected threads under ultrasound?
Dr. Abdelaziz: Standard surgical hooks are often too sharp and tear adjacent tissue. Dr. Abdelaziz repurposes a blunt knitting or crochet needle: “I put it out of its autoclave so you can make it sterile, and you can use it… to catch the thread under ultrasound and pull it out without making incisions.”
Q: Can ultrasound prevent nerve injuries during facial thread lifting?
Dr. Abdelaziz: While individual motor nerve twigs are difficult to visualize on ultrasound, mapping prevents injury to known danger zones. Dr. Abdelaziz notes that long-term post-procedure pain most commonly arises from hitting superficial sensory branches, such as the great auricular nerve behind the ear, causing neuralgia that can persist for 3 to 4 months. Staying in the superficial subcutaneous plane avoids deep nerve pathways.
Dr. Ahmed Abdelaziz is an Aesthetic plastic surgeon consultant and internationally recognized expert in body sculpting, body contouring, and facial aesthetic procedures. He is a member of the Royal College of Surgeons of England and has extensive experience in advanced aesthetic and minimally invasive techniques. Dr. Ahmed has a special interest in integrating ultrasound into aesthetic practice, particularly in facial procedures.

Your Probes, Our Platform: Clarius at IEEE IUS 2026
Ultrasound researchers have long had to choose. Cart-based systems come with familiar probes, but their data stays locked inside the machine. Open research platforms give you the data, but usually mean new probes, new hardware and a steep learning curve. At IEEE IUS 2026 in Raleigh, Clarius is showing a research offering built so you don’t have to choose.
Visit us at booth #35 from October 4 to 8 to see it in action.
See the Signal, Not Just the Image
Every ultrasound image starts as raw echo data. Clarius research scanners give you that data directly, as RF and IQ, before it is turned into a picture. That matters if you are developing new ways to form images, training AI models, or measuring tissue properties that a finished image hides.
Because the scanner is wireless and handheld, the same research setup works at the bench, at the bedside or in the field.
Texo II: Decide How the Probe Sends and Listens
An ultrasound image is built from a sequence: the pattern of pulses a probe sends and the echoes it listens for. Texo II is Clarius’s sequencing software, and it hands that sequence to the researcher.
Work at the level you need. Describe a whole imaging frame, or go down to individual events and choose which probe elements fire each pulse.
Shape every transmit. Set the pulse shape, focus, frequency, f-number and aperture.
See changes right away. Adjust parameters while imaging, or apply an edited sequence to the probe in one step.
Start from working examples. Included scripts cover B-mode, RF, channel data, color and pulsed-wave Doppler, M-mode, contrast and compounding.
Texo II opens up the same tools Clarius engineers use to tune our own imaging. It first went to select research customers this year, and becomes generally available with Clarius 13.1.
A First Look: Bring Your Own Probe
Clarius Research Hardware with ZIF Connector
The highlight at our booth this year is a preview of new Clarius research hardware with a ZIF (zero insertion force) connector. With adapters from Probe Hunter, it connects probes from cart-based and laptop-based ultrasound systems to a Clarius research device running Texo II.
For research labs, that means:
Reuse the probes you already own instead of buying new ones to get open data access.
Compare different probes on one consistent acquisition system.
Get more from existing equipment by pairing it with modern, open data access.
This hardware is being shown ahead of release. Talk to our research team at the booth to see it running and to hear about availability.
Built for Researchers
“Researchers shouldn’t have to give up the probes they know to get at their data. With Texo II and open raw data, the whole imaging chain is in their hands, from the pulse that leaves the probe to the numbers that come back,” said Kris Dickie, CTO at Clarius Mobile Health.
See It Live at IUS 2026
We’ll be running live demonstrations at booth #35 throughout the symposium, including an adapted probe running on a Clarius research device and live sequence editing in Texo II.
