About this study
Official title: Efficacy of SAM Sport as an Addon to Traditional Therapy in Treating Sports-related Injuries
Low-intensity continuous ultrasound (LICUS) is an FDA-approved bio regenerative technology, applied with a wearable device (SAM, Zetroz Systems LLC) for daily use. The treatment provides long-duration ultrasound for approximately four hours. This report included a retrospective convenience sample of 6 athletes from one sports medicine and rehabilitation facility. The objective of this report is to examine the real-world outcome data on symptoms improvement and return to function using Sam. It was hypothesized that LICUS stimulation, in conjunction with traditional therapies, will accelerate the healing process of musculoskeletal tissue leading to a reduction in pain, increase functionality, and a higher probability of returning to work and sports-related activities. The sample included athletes with sports-related musculoskeletal injuries. Demographics, injury history, treatment history, and clinical outcomes data were retrospectively collected for athletes who were treated with SAM in conjunction with traditional therapies. Clinical results showed a benefit from the treatment with a decrease in pain (100%), and 3 out of 6 athletes were able to return to work or sports (50%). Overall the study shows that Sam accelerates the healing of soft tissue leading to a decrease in both acute and chronic pain.
Read the detailed description
The cohort of 6 male athletes (n=6) ages ranged from 18 to 54 years of age, with an average age of 33.5 years with musculoskeletal injuries, which showed little or no improvement with traditional therapies selected from one rehabilitation facility. The group included 3 amateur athletes and 3 professional athletes participated in baseball (2) and golf (1). No healthy athlete was selected, considering the study of nature.
Demographic, injury history, treatment history, and clinical outcomes data of the patients were collected. The patients were asked about the effectiveness of traditional therapies such as physical therapy, manual therapy, a combination of rest, ice, compression, and elevation (RICE). The athletes with sports-related musculoskeletal related injuries, including arm, upper leg, back, quadriceps, knees, foot/ankles, were treated with low-intensity continuous ultrasound (SAM®, ZetrOZ Sysmtem LLC device) in conjunction with traditional therapies. At that point, data were recorded, and patients were advised to use LICUS in conjunction with conventional therapies. The athletes were asked about the effectiveness of LICUS treatment as an add-on to traditional therapies. Furthermore, .the effectiveness of the treatment was assessed by patient response to pain relief, range of motion, and ability to going back to the sport.
The LICUS was delivered by easy to use wearable LICUS device (SAM®, ZetrOZ Systems, LLC, Trumbull, CT) consisting of two transducers powered by an external battery pack was used to deliver at 3MHz, 0.132W/cm2, 1.3W for 4 hours. The athletes were trained to use the device using ultrasound coupling gel on the injured area. It was ensured that all the athletes knew how to use the device properly. The device is easy to use with three buttons setup: an on/off button (middle), a time, and on/off lock buttons on the sides.

What is being measured
The primary outcome is the main question the study is designed to answer.
Numeric Pain Rating Scale (NRS) (0-10)
Change in pain severity over the time of treatment, 0 being lowest, and 10 being the worst pain. A total of 6 athletes were examined through questionnaires. in which they were asked about the change of pain on the NRS scale. No adverse effects were reported throughout the study.
Measured: variable (1 - 8 weeks)

Questions about this trial
What is this clinical trial studying?
An observational study of Pain, Chronic and Pain, Acute, run by ZetrOZ, Inc..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Numeric Pain Rating Scale (NRS) (0-10) (time frame: variable (1 - 8 weeks)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04177537, which also lists 16 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Nov 2019.
