CONCLUSION: This study showed the effectiveness of complex non-invasive treatment in patients with arthralgia of the TMJ. The analgesic and anti-inflammatory effects of LASER THERAPY were confirmed by infrared thermography.
OBJECTIVE: The purpose of this study was to evaluate the effectiveness of low intensity laser therapy (LILT) for the control of pain from temporomandibular disorder (TMD) in a random and double-blind research design
CONCLUSION: Results show that low intensity laser is an effective therapy for the pain control of subjects with TMD.
OBJECTIVE: The purpose of this study was to evaluate the analgesic effect of Low Intensity Laser Therapy (LILT) and its influence on masticatory efficiency in patients with temporomandibular dysfunction (TMD).
CONCLUSION: Low intensity laser application is effective in reducing TMD symptoms, and has influence over masticatory efficiency [Ev2 (0.2423) and Ev3 (0.2043), observed in the interaction Evaluations x Probes for effective dosage].
OBJECTIVE: We investigated if low level laser therapy (LLLT) of the joint capsule can reduce pain in chronic joint disorders.
CONCLUSION: Low level laser therapy with the suggested dose range significantly reduces pain and improves health status in chronic joint disorders, but the heterogeneity in patient samples, treatment procedures and trial design calls for cautious interpretation of the results.
OBJECTIVE:
A randomized, single-blind, placebo-controlled study was conducted to evaluate the efficacy of low-energy laser therapy in female patients with fibromyalgia.
CONCLUSION: Our study suggests that laser therapy is effective on pain, muscle spasm, morning stiffness, and total tender point number in fibromyalgia and suggests that this therapy method is a safe and effective way of treatment in the cases with fibromyalgia.
OBJECTIVE: To assess the efficacy of low level laser therapy in patients with primary Raynaud's phenomenon and predict the success of laser therapy by clinical characteristics.
CONCLUSION: Low level laser therapy reduces frequency and severity of Raynaud attacks. The effect is most pronounced in patients with signs of decreased threshold for vasospasm and less effective in patients with delayed hyperemia.
OBJECTIVE: The purpose of this study was to systematically review and meta-analyze the therapeutic effects of Laser Therapy on Lateral Epicondylitis.
CONCLUSION: We suggest that using LASER THERAPY on tender points or MTrPs of LE could effectively improve therapeutic effects.
OBJECTIVE: The aim of this study was to evaluate the effectiveness of 904-nm low-level laser therapy (LLLT) in the management of lateral epicondylitis.
CONCLUSION: This study revealed that LASER THERAPY in addition to exercise is effective in relieving pain, and in improving the grip strength and subjective rating of physical function of patients with lateral epicondylitis.
OBJECTIVE: The aim of this clinical study was to assess the efficacy of LLLT using trigger points (TPs) and scanner application techniques under placebo-controlled conditions.
CONCLUSIONS: This clinical study has demonstrated that the best results are obtained using combination treatment (i.e., TPs and scanner technique). Good results are obtained from adequate treatment technique correctly applied, individual energy doses, adequate medical education, clinical experience, and correct approach of laser therapists. We observed that under- and over-irradiation dosage can result in the absence of positive therapy effects or even opposite, negative (e.g., inhibitory) effects. The current clinical study provides further evidence of the efficacy of LASER THERAPY in the management of lateral and medial epicondylitis.
OBJECTIVE: Recent reviews have indicated that low level level laser therapy (LLLT) is ineffective in lateral elbow tendinopathy (LET) without assessing validity of treatment procedures and doses or the influence of prior steroid injections.
CONCLUSION: LASER THERAPY administered with optimal doses of 904 nm and possibly 632 nm wavelengths directly to the lateral elbow tendon insertions, seem to offer short-term pain relief and less disability in LET, both alone and in conjunction with an exercise regimen. This finding contradicts the conclusions of previous reviews which failed to assess treatment procedures, wavelengths and optimal doses. This study also affirms that LLLT (photobiomodulation) is inadequate in producing clinical benefits, and that more appropriate doses in the high-level range are needed.
OBJECTIVE: This study was undertaken to compare the effectiveness of a protocol of combination of laser with plyometric exercises and a protocol of placebo laser with the same program, in the treatment of tennis elbow.
CONCLUSION: The results suggested that the combination of laser with plyometric exercises was more effective treatment than placebo laser with the same plyometric exercises at the end of the treatment as well as at the follow-up. Future studies are needed to establish the relative and absolute effectiveness of the above protocol.
OBJECTIVE: This study aimed to establish cellular responses to laser irradiation using different laser fluences (0.5, 2.5, 5, 10, and 16 J/cm(2)) with a single exposure on 2 consecutive days on normal and wounded human skin fibroblasts
CONCLUSION: Results show that 5 J/cm(2) stimulates mitochondrial activity, which leads to normalization of cell function and ultimately stimulates cell proliferation and migration of wounded fibroblasts to accelerate wound closure. Laser irradiation can modify cellular processes in a dose or fluence (J/cm(2)) dependent manner.
OBJECTIVE: In this study I sought to test the efficacy of low-power laser therapy (LLLT) in patients with frozen shoulder
CONCLUSION: The results suggested that laser treatment was more effective in reducing pain and disability scores than placebo at the end of the treatment period, as well as at follow-up.
OBJECTIVE: This is a pilot, randomized clinical study about the effect of high intensity laser therapy in patients with osteoarthritis of the knee (OA of the knee)
CONCLUSION: The results after seven days of treatment show more intensive and cumulative effect after the application of high intensity laser therapy in comparison to sham laser. This is the reason why HILT can be a method of choice in the treatment of gonarthrosis
OBJECTIVE:
Diabetic peripheral neuropathy (DPN) is frequently the most common microvascular complication of both type I and II diabetes; it is thought to be progressive and irreversible.
CONCLUSION:
Low level laser therapy within the applied parameters and technique could be an effective therapeutic modality in reducing pain and improving neurovascular function in patients with diabetic polyneuropathy.
OBJECTIVE: To investigate the effect of high intensity laser therapy, alone or combined with exercise on pain, health related quality of life and fall risk in patients with osteopenia or osteoporosis.
CONCLUSION:
High intensity laser is an effective modality for patients with osteopenia or osteoporosis. Laser combined with exercise is more effective than exercises or laser alone in decreasing pain, fall risk an increasing quality of life after 12 weeks of treatment.
OBJECTIVE: The objective of this study was to evaluate the effect of a conjugated therapy between ultrasound and laser therapy, in a symptomatic patient of fibromyalgia, considering as region of application of therapy the palms of the hands.
CONCLUSION: After treatment, it was observed a reduction of 8.900% in pain (Visual analogue Scale) and an increase of 335% (Fibromyalgia Impact Questionnaire), enabling the patient to return to daily activities.
OBJECTIVE: Among the various methods of application techniques in laser therapy (HeNe 632.8 nm visible red or infrared 820-830 nm continuous wave and 904 nm pulsed emission) there are very promising "trigger points" (TPs), i.e., myofascial zones of particular sensibility and of highest projection of focal pain points, due to ischemic conditions.
CONCLUSION: Results measured according to VAS/VRS/PTM: in acute pain, diminished more than 70%; in chronic pain more than 60%. Clinical effectiveness (success or failure) depends on the correctly applied energy dose--over/underdosage produces opposite, negative effects on cellular metabolism. We did not observe any negative effects on the human body and the use of analgesic drugs could be reduced or completely excluded. LASER THERAPY suggests that the laser beam can be used as monotherapy or as a supplementary treatment to other therapeutic procedures for pain treatment.
OBJECTIVE: The efficacy of laser therapy in myofascial pain syndrome (MPS) seems controversial - Our aim was to clarify the effect of LLLT in MPS by using algometry and thermography.
CONCLUSIONS: LASER THERAPY seemed to be beneficial for pain in MPS by using algometry and thermography, provided dosages higher than LLLT are utilized.
OBJECTIVE: The authors conducted this pilot study to prospectively investigate the effectiveness of low-power laser irradiation (780 nm) in the treatment of patients suffering from incomplete peripheral nerve and brachial plexus injuries for 6 months up to several years
CONCLUSION: This pilot study suggests that in patients with long-term peripheral nerve injury noninvasive 780-nm laser phototherapy can progressively improve nerve function, which leads to significant functional recovery.
OBJECTIVE: This paper reports the effects of laser therapy in 4 patients with longstanding sensory nerve impairment following mandibular third molar surgery
CONCLUSION: Low level laser therapy seemed to be conducive to the reduction of long-standing sensory nerve impairment following third molar surgery. Further studies are worthwhile regarding the clinical application of this treatment modality.
OBJECTIVE: The objective of this study was to analyze the effect of single laser therapy irradiation on pain perception in patients having fixed appliance treatment
CONCLUSIONS: LASER THERAPY immediately after multi-banding reduced the prevalence of pain perception at 6 and 30 hours. LASER THERAPY has positive effects in orthodontic patients not only immediately after multi-banding, but also for preventing pain during treatment.
OBJECTIVE: The effectiveness of LLLT for rheumatoid arthritis is still controversial, due to its comparatively low dosage. This review is an update of the original review published in October 1998, and suggests that higher power output (higher dosage) is necessary for effective treatments.
CONCLUSION: LASER THERAPY could be considered for short-term treatment for relief of pain and morning stiffness for RA patients, particularly since it has few side-effects. Clinicians and researchers should consistently report the characteristics of the LASER THERAPY device and the application techniques used. New trials on LASER THERAPY should make use of standardized, validated outcomes. Despite some positive findings, this meta-analysis lacked data on how LASER THERAPY effectiveness is affected by four important factors as higher dosages were not utilized (duh): wavelength, treatment duration of LASER THERAPY, dosage and site of application over nerves instead of joints. There is clearly a need to investigate the effects of these factors on LASER THERAPY effectiveness for RA in randomized controlled clinical trials.
