Class IV Laser in Non-invasive Laser
The title must have awakened curiousness of every supporter of non-invasive laser therapy, or at least a bit of amusement. Since the very first small steps on the long and manifold path of laser medicine we have been aware that despite dynamic development of this technique, yet there is a couple of firm reference points. Laser will always mean radiation of light with perfect coherence and monochromaticity. We will never direct a laser in the eye and we will always mind also other contra-indications. Lasers in class IIIa and IIIb are intended for applications in terms of non-invasive laser therapy (LLLT), whilst class IV lasers are meant for use in surgical specialties ... Or perhaps, maybe it is not quite so ?
Output power is one of the most important parameters of a laser, indirectly
affecting also the spectrum of possible applications as well as time
required to perform therapy. Years back, low level laser therapy (LLLT)
manufacturers had provided devices fitting into class IIIa, often with
output power not exceeding 3 or 5 mW, especially HeNe sources which
were mainly used for superficial conditions, such as wound healing.
Expansion of application spectrum of LLLT into pain management and therapy
of locomotive apparatus clearly pointed to the need of higher output
levels and, similarly, led to implementation of other wavelengths with
deeper penetration in tissue (IR). Nowadays, therapists usually work
with infrared laser probes with 300 and more milliwatt of power, and
values of 450 - 500 mW represent an imaginary boundary for both manufacturers
and therapists, behind which laser devices are classified in laser class
IV, with all consequences in terms of hygienic rules and labour safety
applicable. There is no need to remark that hand in hand with increasing
output of non-invasive lasers, as well as due to long-term clinical
experience, higher and higher dosages of energy are also being administered.

"Leonardo Fernández Sánchez" , Cienfuegos, Cuba.
Herpes simplex is an illness caused by the human herpes virus types 1 and 2 that generally present a primary lesion, with periods of latency and a tendency to relapse. It is also known as Button of fever or Bladder of fever. According to the World Health Organisation (WHO) an international prevalence of about 60% is observed (1, 2).
An experimental study was carried out, where 232 patients affected by the Herpes simplex type 1 virus were treated. All patients attended the clinic "Leonardo Fernández" of the area 3 of the municipality of Cienfuegos, during the period of January 2001 to January 2003, with the objective of determining the time of recurrence of the labial Herpes in the groups, studied before and after treatment, and to evaluate the effectiveness of the Laser of low power in the treatment of the infection of the virus.
Two groups were selected (study and control) with 116 patients in each group, distributed and classified according to the clinical stage in which they went to consultation. In the study group the patients were offered treatment with a LASERMED 670 DL, a GaAlAs diode laser (30mW – 40 sec) in the prodromal stage and stage of vesicles; or (20mW – 2 min) in the crust stage and in lesions infected secondarily. To all these patients was also applied radiation among the vertebras C2-C3 where the resident ganglion of the virus is located during the latent periods (30mW - 30sec).
The control group was offered indicated treatment with antivirals (Aciclovir in cream and in pills) and other palliative therapies.
After having carried out the analysis of the data obtained, the following results were obtained:
Chart No. 1
The patients of the study group. Distribution according to the frequency of annual recurrence of the labial herpes before and after receiving treatment.
When analyzing the chart No.1 it is observed that the groups of patients that had Labial Herpes with high frequencies of recurrence (after being treated with Laser and to wait one year to evaluate their effectiveness), reported recurrence for more elongated periods of time and 32 patients didn't even have any more recurrence.
The patients of the control group. Distribution according to the annual recurrence frequency of the labial herpes before and after receiving treatment.
In the chart No. 2 the same previous aspects are reflected but in the control group. As can be observed the cases diminished in number, although discreetly; those that presented more recurrence and of equal number of recurrencies increased in number of patient in the periods of more lingering recurrence. In this group 2 patients reported not to have had more lesions during the analyzed year.
The patients of both groups. Distribution according to the annual recurrence frequency of the labial herpes after receiving treatment.
In the chart No. 3 are compared both groups as for the annual frequency of recurrence after having received the corresponding treatment. When analyzing this, the superiority of the group treated with Laser becomes evident.
Chart No. 4
The patients' of both groups. Distribution with relationship to the clinical stage in that we intervened and the time of cure of the same ones.
As can be observed in the chart 4, in the study group 100% of the prodromal stages, 95% of the vesicular ones and 91% of crust stages were able to cure during the first 48 hours. The patients with lesions infected secondarily needed more than 48 hours to cure, although they never surpassed 5 days.
These results, although astonishing, are corroborated by authors like Tunér and Schindl where they highlight that a treatment with laser in the initial stages of the Labial Herpes has a percentage of superior success compared to conventional treatments, besides achieving an almost immediate relief of the symptoms (3, 11).
In the control group remarkable differences are appreciated when comparing them with that of the study group. The therapy with Aciclovir in early stages (the first 72 hours) has been broadly suitable for many professionals and their use against the Labial Herpes has been studied by some authors (5).
- The periods of annual recurrence in the study group were prolonged considerably after having received the treatment, while in the control group so evident changes were not shown.
- In the prodromal period the patients treated with Laser all cured in the first 48 hours, while those treated conventionally needed from 3 to 4 days to cure. - In the vesicular period and of crust, those of the study group cured in majority during the first 48 hours, while those of the control group needed more than 5 days.
- In infected lesions those treated with Laser cured mainly from 3 to 4 days, while those treated with medications needed more than 7 days to cure.

|LASER ACUPUNCTURE FOR INDIAN NATIONAL
(This paper is extracted from seminar paper for WALT 2002 Congress,
The trial was based on an elaborate model identifying four modalities of laser application to serve as a mono therapy on the training field, to take care of correction, and prevention of injury and health setbacks. Laser irradiation and Trigger point stimulation were given for localized, peripheral conditions, whereas single point laser acupuncture and auriculotherapy were given for systemic effects of the CNS. An assortment of problems ranging from headaches, cervical pain, lumbago, tendinitis and skin allergy were treated effectively through these modalities.
However a unique condition was observed during the trial that affected the players at the onset of the six-day training. There were recurrent reports of exhaustion, lethargy, lack of motivation and a difficulty in maintaining concentration throughout 18 holes of golf. As laser acupuncture was one of the therapeutic modalities involved the condition was diagnosed as a depletion of Kidney Jing and Yin essence affecting all the players, based on the climatic conditions to which players were exposed. This diagnosis is revealed in Chapter Three of the Yellow Emperor’s Classic, and the remedy is available through laser acupuncture.
A close look at the climate showed conditions of escalating heat of about 38 degrees C, coinciding with the onset of summer. The first week of April in North India marks a transition from spring to summer, when the body utilizes immense stores of energy for effective adaptation. The trees are flowering creating high pollen count in the atmosphere. The heat is dusty, static and dry, creating dehydration of fluid stores from the body. At this time the players were exposed to seven hours of exposure to peak heat. Most of them had collected from different parts of India after several weeks of high school examination study during which they were off golf training, indicating they were probably not in peak athletic form.
Oriental medicine pays careful attention to environmental affects on the body and this is useful for golfers who are unaware of the hazards of climate. Whereas laser therapy in sports medicine conventionally approaches therapy as localized, based on overloading, overuse, sprains, strains and nerve compression, the circumstances of sport in tropical countries as India show the need for therapy that is systemic and centralized. Western medicine recognizes that heat conditions of 38 degrees C approaches danger zone for athletes. 40 degrees C and above can cause a permanently degenerative effect on the hypothalamus and indeed can prove fatal in heat stroke and dehydration. In addition, exposure to harmful UV rays from the sun cause skin allergies, and glare from the sun causes headaches. Laser acupuncture in conjunction with laser therapy acts on the autonomic nervous system on the field to assist golfers through the hazards of climate.
The Yellow Emperors Classic from which acupuncture theory is derived pays much attention to health imbalances through the seasons, and Chapter three makes reference to the climatic conditions corresponding to a change of season approaching summer as bringing on the Jian Jue syndrome when the body is overworked and the Yang overheats causing a depletion of Kidney Jing and syncope of the yin fluids causes consumption of yin fluids. The TCM (Traditional Chinese Medicine) Kidney is essentially different from the Kidney of Western Medicine which treats it specifically as an organ. In Oriental Medicine the Kidney stores genetic essence or ancestral chi, and frames the constitution of the individual. Whereas health is a balance of Yin and Yang function, TCM regards Kidney Jing as the root of Yin and Yang in the body. When climate causes a depletion of Jing the energy drain is touching constitutional stores, which creates a feeling of energy loss at the deepest level where the person can no longer cope. Subsequent injuries that arise from a depletion of Jing essence are likely to respond slowly to any therapy as the Kidney reservoir is inherited and the Jing stores have to maintain the body throughout a lifetime. The loss of Jing is permanent and irreversible. Most of TCM theory of health is based on nourishing Kidney Jing and illness is attributed to weak Jing constitution. When Jing stores are drained there is energy loss at the deepest level and motivation, concentration and will power are likely to be affected. Indeed TCM claims that Kidney stores Zhi, in its higher octave or soul nature, Zhi referring to the inherited will power, goals and ambitions of the individual that are going to shape the life achievements of the individual. The Jian Jue syndrome naturally will affect Zhi, or the motivation and will power of the player under the hazardous climatic circumstances.
Dr Michael Tierra, OMD, (1) has conveyed most lucidly the correspondence to Kidney Yin and Kidney Yang in Western Medicine. The TCM kidney encompasses the urinary system, balance of mineral electrolytes, as well as the entire endocrine system including prostaglandins and neurotransmitters. The adrenal gland functions and release of glucocorticoids (the most significant stress buffer for athletes) is also regulated by Kidney Yin. Kidney Jing stores the root of Yin and Yang of the entire body, and regulates homeostasis through the sympathetic nervous system or Kidney Yang, and the parasympathetic nervous system or Kidney Yin. The availability of ATP and ADP is also considered to be a function of Kidney Jing whereby cellular energy may be generated at all times.
each acupuncturist has his own experience with specific points, this
trial tested the point Kidney 5 for the stimulation of the Kidney pathway
to prevent loss of Jing. The likely results of this point are that further
deterioration will immediately be prevented. The laser used was the Medicom Maestro 830nm 30 mw probe, 1168 Hertz delivered at 1 joule/cm 2 , approx 33 seconds. 1168 hertz was selected because Kidney is a mesodermal organ forming the musculoskeletal structure and Nogier recommends Freq C, 1168 hertz for mesodermal tissue.
Whereas at the start of the trials there were numerous reports of lethargy, poor motivation and poor concentration, it was noted that by the third day of the six-day trials there were substantially fewer complaints. Kidney 5 was given everyday with Spleen 6 and players indicated a return to normalcy despite intensified training. The treatment was effective as no further calamities were reported during the week. Motivation and concentration also improved simultaneously
