Summary
This review introduces simplified laser dose parameters for low-power laser therapy. These new parameters aim to improve the accuracy and reproducibility of low-level laser therapy (LLLT) research and clinical outcomes.
Area of Science:
- Biomedical Engineering
- Photomedicine
- Laser Therapy
Background:
- Low-power lasers are utilized for treating soft and bone tissues, with rapid advancements in research forming the basis for therapeutic protocols.
- Comparing experimental and clinical outcomes is challenging due to complex, often omitted or inaccurately reported, physical and biological parameters in low-level laser therapy (LLLT).
Purpose of the Study:
- To review physical and biological parameters for accurate and reproducible experimental and clinical protocols in low-power laser applications.
- To propose simplified dose parameters based on laser-induced biological effects for low-power laser therapy.
Main Methods:
- Literature review focusing on physical and biological parameters used in low-power laser research.
- Definition and proposal of novel 'laser dose' and 'laser dose equivalent' parameters.
Main Results:
- Identified a complex and often inconsistently reported list of over three dozen parameters in existing low-power laser literature.
- Defined 'laser dose' and 'laser dose equivalent' as simplified parameters directly linked to biological effects.
Conclusions:
- The proposed laser dose and laser dose equivalent parameters can simplify reporting and improve comparisons between studies.
- These parameters are expected to enhance the accuracy, effectiveness, and safety of clinical protocols utilizing low-power lasers.

The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...

A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...

224
In healthy individuals, serum creatinine levels remain stable due to a balance between its constant production—primarily from muscle metabolism—and renal excretion. Creatinine is freely filtered by the glomeruli, making it a valuable marker for estimating renal function. When the glomerular filtration rate (GFR) decreases, the kidneys can only eliminate less creatinine, causing serum levels to rise.Serum creatinine concentration is widely used to estimate creatinine clearance...

5.5K
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...

Instantaneous power is important in electrical circuits, mainly when dealing with sinusoidal input. Instantaneous power, denoted as p(t), results from the multiplication of the instantaneous voltage (v(t)) across an element and the instantaneous current (i(t)) flowing through it. This relationship adheres to the passive sign convention and represents a fundamental principle in electrical engineering.
