About this study

Official title: Effect of Photobiomodulation on the Treatment of Soft Tissue Traumatic Injuries: Study Protocol for a Double-Blind, Randomized, Controlled Trial

Soft tissue injuries are directly related to the energy of the trauma and its repair is the main factor for bone healing and the recovery of the function of the affected limb. Photobiomodulation (PBM) is indicated as an adjuvant treatment to accelerate wound healing, however, there is still a lack of evidence regarding its effect on traumatic soft tissue injuries. This project aims to evaluate the effects of the application of PBM in the resolution of complex soft tissue injuries of traumatic origin associated with tibial fractures. 84 adult individuals, aged between 18 and 60 years, hospitalized with tibial fractures awaiting resolution of soft tissue injuries will be included to undergo definitive surgery. The subjects will be randomized in two groups: PBM (treated with a device with 144 LED emitting diodes at wavelengths of 420, 660 and 850nm, 3J per point for 10 minutes) and Sham (simulation of the LED application, with a device with characteristics identical to that of the PBM group, for the same period of time). Subjects will be treated daily until release for surgery. The primary outcome will be the assessment of the wound healing process using the BATES-JENSEN scale. Secondary outcomes will be: pain intensity; consumption of analgesic drugs; serum evolution of inflammatory markers C-reactive protein and creatine kinase, measurement of the lesion area, time needed for release for definitive surgery, presence of infection, and the cost-effectiveness of PBM. The evaluations will be carried out before the beginning of the intervention and daily until the participant is considered ready for surgery (which will be considered the end of the experimental period). Data will be analyzed statistically considering a significance level of 5%.

Photobiomodulation groupActive comparatorIn this group, PBM will be applied daily using LED devices until the lesion presents healthy granulation tissue, absence of necrosis and purulent secretion and, therefore, is suitable for primary closure, closure by flap or graft or for healing by second intention. At this point, the protocol will be finalized.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change of the wound healing process using the BATES-JENSEN scale

    Evaluation of the healing process of soft tissue injuries in lower limbs associated with tibial fractures caused by high-energy trauma using the variation in the Bates Jensen Wound Assessment Tool scale score. The current version of BWAT contains 13 items that measure size, depth, borders, detachment, type and amount of necrotic tissue, type and amount of exudate, edema and hardening of the peripheral tissue, skin color around the wound, granulation tissue and epithelialization. The measurement scale is of the Likert type, with five points, where 1 indicates the best condition of the wound and 5, the worst condition. The total score is obtained with the sum of all items and can vary from 13 to 65 points, with the highest scores indicating the worst wound conditions. The items size, depth, edges and detachment should be scored as zero when the lesions are healed. The instrument contains two additional items - location and shape - that are not part of the total score.

    Measured: Baseline and through study completion, an average of 1 month.

Secondary outcomes (8)
  1. Change in Pain Intensity Through VAS

    Pain will be assessed by field researchers by applying the visual analogue pain scale (VAS). This scale is represented by a 10 cm line, with the phrases "no pain" and "unbearable pain" at its ends.

    Measured: Baseline and through study completion, an average of 1 month.

  2. Consumption of painkillers

    The type, dosage and frequency of analgesic consumption will be checked and recorded daily during the medical visit by the field team responsible for the daily medical visit. The results will be passed on to the main researcher for storage, tabulation and interpretation.

    Measured: Baseline and through study completion, an average of 1 month.

  3. Change in serum evolution of inflammatory markers

    For laboratory evaluation of the evolution of the inflammatory process and muscle damage, the following tests will be collected: C-reactive protein (CRP), Creatinophosphokinase (CPK), serum urea, creatinine, blood count and coagulogram. These exams will be collected at the time of admission, every three days and when the soft parts are resolved.

    Measured: Baseline, every three days and through study completion, an average of 1 month.

  4. Change in Lesion Area Measurement

    The wounds will be photographed along with a cut of graph paper using the camera of the iPhone 8 mobile device, to allow the calibration of the measurement application. The photos will be taken by the doctors who will visit the patient daily at the patient's bed and pass them on to the main researcher. The images will be stored and later evaluated with the aid of the Image J® application, a public domain Java image processor and analyzer, developed by Wayne Rasband of the Research Services Branch, National Institute of Mental Health, Bethesda, Maryland.

    Measured: Baseline and through study completion, an average of 1 month.

  5. Time needed for liberation for definitive surgery

    Each lesion will be considered solved when it presents healthy granulation tissue, without necrosis or purulent secretion and is, therefore, suitable for primary closure, flap or graft closure or apt to choose healing by second intention. At this point, the protocol will be finalized and this data will be added to the study participant's medical record.

    Measured: Baseline and through study completion, an average of 1 month.

  6. Presence of Infection

    Field researchers will collect information regarding the patient's temperature, blood pressure and heart rate every 24 hours. In addition, the wound will be evaluated for the presence of secretion, necrosis, odor and color. If the wound shows signs of infection (purulent secretion, foul odor, areas of superficial or deep necrosis, accompanied or not by systemic signs such as fever, a fall in general condition, lack of appetite), surgical cleaning of the wound will be indicated, and at this moment, collections of samples for culture and photographs before and after surgical debridement will be carried out by field researchers. The patient will be excluded from the study.

    Measured: Baseline and through study completion, an average of 1 month.

  7. Cost effectiveness of Photobiomodulation

    The cost-effectiveness establishes whether or not a treatment should be implemented as a therapeutic measure, being calculated by the difference between the cost of two interventions proposed as treatment divided by the difference between its consequences. For the evaluation of the cost-effectiveness of photobiomodulation, the "reduction in the score of the Bates Jensen scale" will be considered as the outcome.

    Measured: Baseline and through study completion, an average of 1 month.

  8. Change in Peripheral Perfusion through Clinical Evaluation

    The peripheral perfusion of the affected limb will also be evaluated clinically by two doctors, through palpation of the distal pulses (pedicle and posterior tibial), pain and passive extension of the fingers (to clinically assess the occurrence of compartment syndrome) capillary filling time, limb, granulation of the wound, occurrence of superficial or deep necrosis. In case of vascular involvement of the limb, joint assessment with the vascular surgery service will be requested and the case will be excluded from the study.

    Measured: Baseline and through study completion, an average of 1 month.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Photobiomodulation in people with Soft Tissue Injuries, run by University of Nove de Julho.

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 3 inclusion and 13 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: status not confirmed, as of the sponsor's last update on 24 Apr 2020. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Change of the wound healing process using the BATES-JENSEN scale (time frame: Baseline and through study completion, an average of 1 month.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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?
