Definition of LPTLPT is the abbreviation for Laser Photo Therapy,which means the treatment of symptoms like pain,inflammation or wound healing with non-thermallaser radiaion, LPT is used in various fields like:Pain / inflammation: Wound healing: - Arthrosis - Burns - Epicondylitis - Scars / Keloids - Carpal Tunnel Syndrom - Ulcus cruris - Diabetic footSport Injuries: Others: - Luxation - Tinnitus - Distortion - Acne - Fracture - Facial Paresis - Shoulder-Arm-Syndrom - Zoster

Accelerated wound healing
History of LPTIn 1963 Endre Mester performed the first trreatmentof lasers on mice. He found a stimulation of hairgrowth on the treated spots.*In later studies he found also an increasedepithelization of wounds.*** Endre Mester, B.Szende u.a.: The effect of laser beams onthe growth of hair in mice. In: Radiobiol Radiother. 9/1968,S.621-626** Endre Mester: Laser - induced stimulation of thevascularisation of the healing wound. In: Separat.Exp.30/1974, S.341-345
Scientific EvidenceIs there scientific evidence for LPT?The answer is clearly: YES - More than 3000 scientifical and clinicalpublications listed in PubMed* - More than 160 randomized placebo controlleddouble blind studies*** **: December 2011

Laser Light and BiophotonsA laser emits a special sort of light which ismonochromatic(only one colour ==> highest power intensity)and• coherent(all waves oscillate parallel to each other)Biophotons of the body emit alsocoherent light* Wave peaks and wave troughs are parallel to each other * Prof. Dr. Fritz-Albert Popp, Int. Institute for Biophysics, Neuss www.biophotonen-online.de

Treatment depth versus treatment time
The ATP synthesisATP (Adenosine-Tri-Phosphate): themolecular energy for each cell of the bodyand the skin.It is built in the mitochondria, the powerstation in each cell. The light is absorbedby components of the cellular respiratorychain namely cytochrome c oxidase (COX).If there is too less ATP available, the cell Mitochondriacannot follow its functions 100%LaserCat & PalmLaser bring energy to themitochondria where it is used to producemore ATP - which means new energy forthe cell.Regeneration of the cell, the tissue and thebody can be seen already after a fewtreatments.

Contraindications / Precautions Patientes with cardiac pacemaker in the area of the thorax Pregnant women in the area of the abdomen Patients with cancer Skin diseases without diagnose Epilepsy patientsno radiation on: Open eyes Thyroid gland Solar Plexus Childs epiphysis Open fontanel of infants
Side effectsThe Laser Photo Therapy has only very few side effects:The treatment effect can be:• A little tingeling in the treated area• A warm feeling in the treated area (blood flow!)• A higher sensitivity in open wounds• If too much energy is used, a surpressing effect can take placeFurther there can be• Some tiredness• Increased sweating
Why should I start using LPT – New Paradigma Very broad indication range of LPT & No or negligible side effects ->Trade off between beneficial effect and side effects always in favour of treatment -> Therapy possible without secure diagnosis
Safety considerationsEye protectionParallel laser beams are of great danger for theeyes. The beam can be focused by the eyes anddamage the retina irreparable ! (Class 3b & 4lasers)Laser light which is coming through the closedeyes is not dangerous as the light is not focused, itis diffuse.PalmLaser are class 1M lasers and emit adivergent beam, which becomes only danger, bylooking into it directly for more than 100 seconds.A divergent beam can not be re-focused by theeyes. Therefore PalmLaser are much safer thanclass 3b lasers.There are no precaution actions necessary for aclass 1M laser.

Advantages for the doctor´s practice using LPT•Highlyprofitablealreadywith 3-2patientsPalmLaser delivers highly effective laser- phototherapy and represents a lucrativeproposition to professionals. Performing regular therapy sessions on 2 -3 patients permonth breaks the threshold of profitability.•PatientloyaltyandacquisitiontoolOffering and delivering effective and safe innovative therapies elevates the image ofthe practice, leading to long term patient loyalty and patient recommendation basedincrease in popularity.•UsingyourassistanttothefullpotentialPalmLaser treatment is easy to perform and can be delegated to less qualified, but welltrainedassistants,thusfreeingthevaluabledoctor‘stimeforotherdutiesandtasks.The assistants can dedicate more time to the patients, thoroughly explaining the thera-py and providing as much personal care and attention as the patients desire.Further the motivation and qualification of the assistant will increase.•EnhancingyourtherapysystemsAbility to perform laser-phototherapy guarantees a real USP advantage for your practice.Despite its proven efficacy and safety, laser-phototherapy is not yet widely spreaddue to the past difficulties with early lasers (i.e. complexity, size and high costs).PalmLaser from MedSolution provides a practical and affordable solution to the pro-blems of the past, making laser-phototherapy accessible, affordable and well withinyour reach!As a part of modern therapeutic approach PalmLaser is an effective and safe therapeu-tic solution to many health problems.
Advantages for the patient using LPT•HighlyefficientPalmLaser delivers highly powerful and potent laser therapy for acute or chronic medicalconditions. PalmLaser supports an array of healing processes at cellular level and signifi-cantly accelerates regeneration. Pain and inflammation reduce swiftly.•Nosideeffects –highly efficient treatment methodToday‘s patient is well informed and demands interventions that are effective,safe andwithout side effects or treatment related harms. Therapy with PalmLaser is safe and pain-less. Side effects have never been noted. PalmLaser is a stand alone therapeutic modalityor can be used in synergy with other therapies, such as physiotherapy or prescriptionmedicines. In some conditions, PalmLaser can entirely replace or largely reduce the needfor other therapeutic interventions.•FastrecoveryLaser-phototherapy helps athletes to return to training or competition faster or withoutexcessively long delay. Portability of PalmLaser allows the treatment to commenceimmediately after the trauma has occurred – The immediate post trauma application oflaser therapy is the most effective way of dealing with injuries for optimum healing andfast recovery.•Premiumtherapyforsupportingthesomaticself-healing mechanismsLaser-phototherapy is a natural and modern therapy that is recognised and appreciatedby many people. Older and the elderly patients in particular value the features and thebenefits of laser-phototherapy. Laser-phototherapy is effective, yet gentle and non-trau-matising. It activates self healing, regeneration and restoration. Improvements achievedwith PalmLaser phototherapy can be life changing and giving new leases to
