Does Higher Hz Mean More Power?
A customer researching cold lasers recently emailed me asking a question about Hz out-put and the power of a cold laser called the Theralaser T2000. Following is her exact question and my reply:
QUESTION:
“Your Theralaser T2000 goes up to P4 1550 so what would 2336 and 4672 be used for and is that more powerful than yours?”
Margot
RESPONSE:
Dear Margot,
Typically the higher the Hz number, the more superficial the laser penetration, and the lower the number the deeper the penetration. In many cases with a superpulsed laser it is not necessary to go any higher than 12000-15000 Hz. The way superpulsed laser works is that in a given window of time the laser will pulse from 200-400 nanoseconds, delivering 10 deep penetrating powerful bursts at 10 Hz or 15,000 shallow pulses at 15,000 Hz. The relatively high power with small Hz # backing up these pulses allows for the deepest possible cold laser penetration to target tissues with the maximum number of photons delivered to the target tissue.
The higher 15K Hz works more superficially delivering more energy faster in the same given time, but delivering the photonic energy on a much shallower level for treatment of skin and wounds. More is not necessarily better, it just depends upon what your needs are and what you want to accomplish. With regards to power, that is measured in milliwats (mW), I have never seen another laser that has a higher peak power than the Theralaser T2000, which delivers 210,000 mW of peak power. Nothing ever comes close to that.

CLINICAL, NURSING & PATIENT CARE SHOULDER PAIN RESEARCH STUDY
Shoulder pain is a common complication in hemiplegic and spinal cord injured patients. It usually starts during the acute rehabilitation phase leading to further activity limitations. The contributing factors to shoulder pain in the both hemiplegics and spinal cord injured patients are related to the neurological and musculoskeletal lesions: muscle weakness, loss of sensitivity, spasticity, impingement and rotator cuff tear. Upper extremity overuse has been proposed as an aggravating factor in the aetiology of shoulder pain in this population. Obesity, age and mental stress are further risk factors.1
Medications Subacromial or intra-articular injections, ultra-sound, local heating and ice application, functional electrical stimulation, exercises or rest, and surgical tendon repair are some of the various inter- ventions proposed for treating the shoulder pain.2,3 Clinical, not randomised, placebo trials report acupuncture, electromagnetic field, and laser possible pain effectiveness.4
TerraQuant (TQ) is a unique device which combines low level pulse laser therapy (LLLT), pulsating infrared radiation, visible red light and static magnetic fields, providing their synergic therapeutic effect (see Table 1). A randomised double-blind controlled trial was designed to test whether the TerraQuant Laser is more effective than a sham device among hemiplegic and spinal cord injuries.
Treating shoulder pain in hemiplegic and spinal cord injured patients: The purpose of a recent study to test the efficacy of the TerraQuant medical device on shoulder pain resulting from inflammation (eg, osteoarthritis, tendonitis and bursitis) is presented here by a lead researcher _ Low level pulse laser therapy, which has been shown to be safe and effective, has as a primary effect, a local time response to direct irradiation _ A statistically greater improvement was seen in those patients receiving TerraQuant, over and above conventional treatment _ Larger trials are now needed to confirm data
HIGHLIGHTS injured patients with shoulder pain and reduced range of motion (ROM) resulting from inflammation (osteoarthritis, tendonitis, bursitis)
Methods:
Research design.The study is a randomised double-blind controlled trial with pre- and post- measures. Two identical unmarked TerraQuant laser devices were used, with one being deactivated. Both the active and sham TQ emitted a flashing red light during treatment sessions. Given that LLLT, infrared and static fields are non visible, it was impossible to detect which TQ was active and which was sham. A convenience sample of 18 subjects fulfilling eligibility criteria participated in the study. Eligible subjects were randomly allocated to either the experimental group (Active TQ) or to the control group (Sham TQ).
Interventions
The TQ treatment consisted of eight sessions, (five minutes per zone) and were performed every second day. The device was applied on the most painful areas as detected by the therapist. One TQ was active with LLLT at 50Hz frequency (Active TQ), while one TQ was deactivated (Sham TQ). In addition, both groups received similar standard conventional therapy: a 30 minute physical therapy treatment according to the diagnosis included one or several of the following: manual therapy, soft tissue manipulation, active ROM and strengthening. Subjects Twenty eligible subjects with moderate Gabi Zeilig MD Department of Neurological Rehabilitation The Chaim Sheba Medical Center Tel Hashomer, Israel Rémi Guibert MD MSc Nutech Health Melbourne, Australia
(VAS) anchored at “no pain” and “worst pain ever experienced”. The total possible score on the scale ranged from 0–10. The same PT and MD assessed all subjects again after completion of the series of eight TQ treatment sessions. Shoulder pain may lead to movement restriction, loss of flexibility and function and causes important quality of life restrictions
Results
Eighteen patients completed the study (mean age 46+15.5, 15 men and three women). Two patients stopped participation because of a lack of time. Twelve subjects suffered from spinal cord injury (SCI), four from paraplegia and eight from tetraplegia. Six subjects had hemiplegia post cere- brovascular accident (CVA). Ten subjects received the Active TQ, and eight received the Sham TQ. Range of movement Subjects in the Active TQ group experienced a statistically significant greater improvement in shoulder ROM (p=0.001) than those in the Sham TQ. Pain Twelve subjects (six active TQ, six sham TQ) had pre- and post-VAS evaluations. They experi- enced a tendency for greater pain reduction (VAS) however not achieving statistical significance (p=0.1). The remaining six patients did not complete the VAS evaluation because of technical reasons.
Discussion and conclusions Shoulder pain is a major and frequent complica- tion for individuals with hemiplegia and spinal cord injury. Shoulder pain may lead to movement restriction, loss of flexibility and function and causes important quality of life restrictions. Many interventions to treat this condition have been reported, yet their effectiveness is questionable. We report the results of a randomised double- blind controlled clinical trial to test the efficacy of LLLT, pulsating infrared radiation, visible red light and static magnetic fields.
The primary effect of LLLT is a local time response to direct irradiation and includes vasodi- latation with increased circulatory flow; increased macrophages and fibroblast activity and improved metabolic function of depressed or damaged cells. Delayed response consists of a systemic effect caused by circulating photoproducts of irradiation to severe shoulder pain were recruited within a period of one month from inpatients and outpatients of one of the departments of neurological rehabilitation affiliated to Tel Aviv University.
Eligibility criteria consisted of:
Procedure
The subjects were assessed by a physician (MD) and by a physical therapist (PT) prior to the beginning of experimentation. The assessments included the medical history, examination of shoulder soft tissues, evaluation of ROM of the glenohumeral joint (GHJ) using a goniometer attached to the chest and the involved arm, and evaluation of pain using a Visual Analog Scale In conclusion, the TQ treatment proved to have greater efficacy than sham treatment in patients with decreased shoulder ROM over and beyond conventional treatment. No side-effects were observed. There was also a positive evolution trend in alleying the shoulder pain; yet because of the small sample it did not reach statistically significance. The results of this study confirm the existing scientific literature on the efficacy of LLLT and static magnet therapy and suggest that that TQ may be an effective and economical tool in the treatment of pain and reduced range of motion in people with shoulder problems following CVA or SCI. These results are of great potential significance to the patients because of the burden and limitations of function due to shoulder pain aggravating their usually limited functionality in daily life.
Larger and randomised trials are needed in order to confirm this preliminary data. in the blood and lymphatic systems. Increased plasma concentrations of certain types of prostaglandins and endorphins have all been identified and play a major role in the mechanism of pain attenuation. LLLT has been shown to be safe and effective.5-8
The mechanism of action of static magnetic therapy is not completely understood. Possible explanations of its beneficial effect on the body include:

Laser Prism AIM Features an FDA 510(k)-cleared LaserStim Accessory, Which Allows Physical Therapists and Chiropractors to Receive Insurance Reimbursements.
SOLON, Ohio–(BUSINESS WIRE)–Multi Radiance Medical, in partnership with Rich-Mar Corporation, has announced a breakthrough with the introduction of its new therapeutic laser, Laser Prism with Area Identification Matrix (AIM) and its FDA 510(k)-cleared LaserStim accessory, to speed relief to chronic and acute pain sufferers. Laser Prism’s specially designed LaserStim accessory can provide simultaneous or independent light and electrical stimulation applications for superior clinical applications and outcomes. In addition to its proven pain-relieving qualities, physical therapists and chiropractors can now be reimbursed for the time spent administering light therapy.
“One of the biggest challenges physical therapists and chiropractors faced with cold laser therapy equipment, up until now, is the fact that laser treatments were frequently not reimbursable by health insurance,” said Douglas Johnson, ATC, EES, CLS, and medical consultant to Multi Radiance Medical. “These professionals knew that therapeutic lasers worked, but struggled with both the initial purchase of the unit and determining what to charge patients for the treatment without reimbursement. The LaserStim accessory and its unique design changes all of that. Time spent administering light therapy with LaserStim is now being reimbursed by insurance. Most physical therapists and chiropractors will see the unit pay for itself in less than one month of treatments.”
The LaserStim is the only FDA-cleared combination emitter available that incorporates multiple radiances, including a super-pulsed laser with 25,000 milliwatts of peak power, red LEDs, infrared and static magnetic field, with electrical stimulation to promote an optimal healing environment. Available through ColdLaserSupplies.com and Quantum-Healing-Lasers.com. Laser Prism and LaserStim are FDA-cleared for temporary relief of minor muscle and joint pain, arthritis and muscle spasm, relieving stiffness, promoting relaxation of muscle tissue, and to temporarily increase local blood circulation where heat is indicated, as well as for the symptomatic relief and management of chronic, intractable pain and adjunctive treatment for post-surgical and post-trauma acute pain.
Physical therapists, chiropractors and other medical professionals are using products such as Laser Prism with Multi Radiance Technology to speed relief of shoulder, joint and carpal tunnel pain, arthritis, tendonitis, fibromyalgia and more. Laser Prism with AIM features four program modes, six setting and sweep frequencies, and a memory function that allows clinicians to save up to 50 individual patient programs.
Low level laser therapy, or therapeutic lasers, have been used for over four decades to help speed
pain relief in patients. Similarly, Transcutaneous Electrical Nerve Stimulation (TENS) units have been used for over four decades to treat musculoskeletal pain. The combination of these therapies has significant pain-relieving properties for patients suffering from chronic and acute pain.
