Comparison of high-intensity laser therapy and ultrasound treatment in the patients with lumbar discopathy. Biomed Res Int. 2015;2015:304328. [PMID: 25883952 PMCID: PMC4390181 DOI: 10.1155/2015/304328]

Comparison of extracorporeal shock wave therapy and high-intensity laser therapy in the treatment of calcaneal spur-related symptoms: clinical outcomes and functional improvement

OBJECTIVE

This study aimed to evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) and high-intensity laser therapy (HILT) in managing calcaneal spur-related symptoms. These non-invasive modalities were compared in terms of their ability to reduce pain and improve functional outcomes.

METHODS

In this randomized clinical trial, patients diagnosed with calcaneal spur based on clinical and radiographic findings were randomly assigned to receive ESWT or HILT. Participants were randomized into two groups to receive either ESWT or HILT, complemented by standardized exercise regimens. Pain intensity was measured using the Visual Analog Scale (VAS), and functional outcomes were assessed with the Foot Function Index (FFI) at baseline, post-treatment, and three months post-treatment.

RESULTS

Both groups showed significant improvements in pain and functional outcomes. In the ESWT group, VAS scores for initial step pain decreased from 7.8 ± 1.0 to 4.0 ± 1.0 post-treatment and further to 3.4 ± 1.0 at three months (p = 0.002). The HILT group demonstrated a similar trend, with scores reducing from 7.5 ± 1.2 to 4.2 ± 1.1 post-treatment and 3.5 ± 0.9 at follow-up (p = 0.001). Total FFI scores improved significantly in both groups, with the ESWT group showing a larger reduction (58.8 to 19.7; p = 0.033) compared to the HILT group (57.4 to 35.4; p = 0.046). No significant adverse events were reported in either group.

CONCLUSION

ESWT and HILT are effective non-invasive options for treating calcaneal spur with ESWT providing slightly greater functional benefits.

Review of Recent Treatment Strategies for Lumbar Disc Herniation (LDH) Focusing on Nonsurgical and Regenerative Therapies

Conservative treatment is primarily performed for the treatment of patients with lumbar disc herniation (LDH), but if it does not respond, surgical treatment can be performed. Surgical intervention has a positive effect on the rapid improvement of LDH symptoms. However, the effectiveness of surgical versus conservative treatment for LDH is controversial, especially regarding long-term effects. Recently, a treatment using platelet-rich plasma (PRP), bone marrow aspirate concentrate (BMAC), low-intensity pulsed ultrasound (LIPUS), etc., has been actively conducted as a treatment to avoid side effects of surgery and promote tissue regeneration. In this paper, the literature evaluating the effectiveness of non-surgical treatment options is reviewed with an emphasis on the effectiveness of clinical application. Several clinical studies have shown that PRP, biomaterials, BMAC, and LIPUS treatment promote tissue regeneration and alleviate symptoms. Although PRP-applied studies have suggested disc height changes, cell therapy and LIPUS treatment have many shortcomings in clinical aspects of tissue regeneration. Therefore, it is necessary to establish a unified, safe protocol and standardize the method of presenting results to confirm the clinical effect of the treatment for impaired intervertebral regeneration in patients with intervertebral disc degeneration (IDD), including LDH.

[Comparative analysis of the effectiveness of modern physiotherapeutical methods of dorsalgia treatment]

OBJECTIVE

To analyze the treatment possibilities of modern methods of physiotherapy as part of the rehabilitation treatment in dorsalgia (DA).

MATERIAL AND METHODS

An examination of 104 patients with DA, who underwent rehabilitation treatment with physiotherapy methods, was performed. Impact of shockwave therapy (SWT), high-intensity laser therapy (HILT) and pharmacopuncture (PP) and combinations of these physiotherapeutical factors were assessed according to the criteria of the International Classification of Functioning, Disability and Health (ICF).

RESULTS

Dynamics of 15 domains of ICF, including the dynamics of the leading ICF domain in DA - b28013 «Pain in back», was studied. Reliable rehabilitation predictions for the positive dynamics of ICF b28013 «Pain in back» domain in patients with DA have been established in the form of equations of SWT, HILT and PP or their combined application impact regression. Effects of the studied physiotherapy variants were compared.

CONCLUSION

SWT is the most effective of the applied monotherapy in relation to the dynamics of b28013 «Pain in back» domain, HILT - on the second place and PP - on the third place. The greatest effect of treatment in relation to the dynamics of b28013 «Pain in back» domain from the combined use of physiotherapeutic factors is provided by SWT+HILT combination, SWT+HILT+PP - on the second place and SWT+PP combination - on the third place, HILT+PP combination - on the fourth place.

The Effectiveness of High Intensity Laser in Improving Motor Deficits in Patients with Lumbar Disc Herniation

BACKGROUND

High-Intensity Laser (HIL) therapy, known for its biostimulatory effects on nerve cell growth and repair, shows promise for improving motor deficits caused by morphopathological changes. This research study aimed to comprehensively assess muscle strength changes through muscle testing, complemented by functional tests evaluating factors contributing to disability in patients with Lumbar Disc Herniation (LDH) and associated motor impairment, following a complex rehabilitation protocol incorporating HIL therapy.

METHODS

A total of 133 individuals with LDH and motor deficits were divided into two groups. Group 1 (n = 66) received HIL therapy followed by standard rehabilitation, while Group 2 (n = 67) underwent only the standard rehabilitation program. Functional parameters, including muscle strength, the ability to walk on tiptoes or heels, and self-assessed fall risk, were monitored.

RESULTS

Both groups showed statistically significant improvements in all monitored parameters. A comparative analysis revealed a significant result for the HIL therapy regimen across all indicators.

CONCLUSIONS

The group undergoing a rehabilitation program with integrated HIL therapy displayed significantly greater improvement in motor deficits, affirming the positive impact of HIL therapy on functional parameters among LDH patients.

Effect of three-volt moxibustion with helium-neon laser irradiation on quality of care in patients with lumbar radiculopathy spondylosis

BACKGROUND

Lumbar radiculopathy spondylosis is a relatively common orthopedic disease with a high incidence rate. It most commonly occurs in the lumbar 4-5 and lumbar 5-sacral 1 vertebrae, which account for approximately 95% of cases. It mostly occurs in people aged 30-50 years old and greatly affects their quality of life.

AIM

To determine the effect of triple-voltage acupuncture combined with helium-neon laser irradiation on the quality of care and improvement of symptoms in patients with lumbar radiculopathy spondylolisthesis.

METHODS

In this study, we selected 120 patients with lumbar radiculopathy spondylosis who were treated at our hospital between June 2019 to June 2020. The patients were divided into control and observation groups according to the random number table method, with 60 patients in each group. Patients in the observation group were treated with three-volt moxibustion combined with helium-neon laser irradiation, and those in the control group were treated with lumbar traction. After 1 month of treatment, the lumbar pain scores, lumbar spine motor functions, clinical treatment effects, and nursing satisfaction of the two groups were compared.

RESULTS

The results showed that acupuncture combined with laser irradiation significantly improved the patients' clinical symptoms, i.e., reduced their low back pain, significantly lower numerical rating scale pain scores in the observation group than in the control group, and better lumbar spine motility than in the control group, compared to lumbar traction. In addition, they were cared for. The treatment effectiveness rate of the observation group was 95.5%, which was significantly higher than that of the control group (81.67%). Satisfaction with care was higher than 90 points in both groups, but the difference was not statistically significant.

CONCLUSION

Our study provides a clinical rationale for the future treatment of patients with lumbar spine disease. However, further extensive research is needed for validation.

Non-Surgical Approaches to the Management of Lumbar Disc Herniation Associated with Radiculopathy: A Narrative Review

Lumbar disc herniation associated with radiculopathy (LDHR) is among the most frequent causes of spine-related disorders. This condition is triggered by irritation of the nerve root caused by a herniated disc. Many non-surgical and surgical approaches are available for managing this prevalent disorder. Non-surgical treatment approaches are considered the preferred initial management methods as they are proven to be efficient in reducing both pain and disability in the absence of any red flags. The methodology employed in this review involves an extensive exploration of recent clinical research, focusing on various non-surgical approaches for LDHR. By exploring the effectiveness and patient-related outcomes of various conservative approaches, including physical therapy modalities and alternative therapies, therapists gain valuable insights that can inform clinical decision-making, ultimately contributing to enhanced patient care and improved outcomes in the treatment of LDHR. The objective of this article is to introduce advanced and new treatment techniques, supplementing existing knowledge on various conservative treatments. It provides a comprehensive overview of the current therapeutic landscape, thereby suggesting pathways for future research to fill the gaps in knowledge. Specific to our detailed review, we identified the following interventions to yield moderate evidence (Level B) of effectiveness for the conservative treatment of LDHR: patient education and self-management, McKenzie method, mobilization and manipulation, exercise therapy, traction (short-term outcomes), neural mobilization, and epidural injections. Two interventions were identified to have weak evidence of effectiveness (Level C): traction for long-term outcomes and dry needling. Three interventions were identified to have conflicting or no evidence (Level D) of effectiveness: electro-diagnostic-based management, laser and ultrasound, and electrotherapy.

High-intensity laser therapy in low back pain management: a systematic review with meta-analysis

Low back pain (LBP) is a widespread health issue affecting people globally and is the second leading cause of missed workdays. High-intensity laser therapy (HILT) promises to decrease pain intensity in LBP patients. The aim of this work was to evaluate the effect of HILT in adult LBP patients. We searched for randomized controlled studies (RCTs) published before January of 2023. Our primary outcome was pain intensity, while our secondary outcomes included disability and flexibility scores. We synthesized the evidence using RevMan v.5.4 and assessed methodological quality with the Oxford/Jadad scale and the Cochrane collaboration's risk of bias tool 1. The model favors the HILT group over the control group in terms of pain intensity after treatment (MD with 95% CI is -1.65 [-2.22, -1.09], p-value < 0.00001, I2=67%), Oswestry disability index (MD with 95% CI is -0.67 [-1.22, -0.12], p-value = 0.02, I2=73%), and Roland disability index (MD with 95% CI is -1.36 [-1.76, -0.96], p-value <0.00001, I2=0%). The patients in the high-intensity laser therapy had statistically significantly lower (low back) pain intensity compared to the patients in the control group. Based on three RCTs, our model also showed the positive effect of the HILT on LBP in terms of the Oswestry disability index and Roland disability index.

High-Intensity Laser Therapy for Musculoskeletal Disorders: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

High-intensity laser therapy (HILT) is one of the therapeutic approaches used in the treatment of musculoskeletal disorders (MSD). The main objective of this study was to examine the effectiveness of HILT for reducing pain and improving functionality in people with MSD. Ten databases were systematically searched for randomized trials published up to 28 February 2022. Randomized clinical trials (RCTs) assessing the effectiveness of HILT on MSD were included. The main outcome measures were pain and functionality. In total, 48 RCTs were included in the qualitative synthesis and 44 RCTs in the quantitative analysis. HILT showed a decrease on the pain VAS (mean difference (MD) = -1.3 cm; confidence interval (CI) 95%: -1.6 to -1.0) and an improvement in functionality (standardized mean difference (SMD) = -1.0; CI95%: -1.4 to -0.7), with low and moderate quality of evidence, respectively. A greater effect was observed when compared with control than with other conservative treatments, both on pain (χ2 = 20.6; p < 0.001) and functionality (χ2 = 5.1; p = 0.02). Differences in the effectiveness of HILT were found depending on the location (χ2 = 40.1 p < 0.001), with further improved functionality in MSD of the knee and shoulder. HILT is an effective treatment for improving pain, functionality, range of motion, and quality of life in people with MSD, although these findings must be treated with caution due to the high risk of bias in the studies. Further clinical trials should be well designed to lower the risk of bias.

TECAR Therapy Associated with High-Intensity Laser Therapy (Hilt) and Manual Therapy in the Treatment of Muscle Disorders: A Literature Review on the Theorised Effects Supporting Their Use

Background: It has been estimated that between 30 and 50 per cent of all injuries that take place throughout participation in a sport are the consequence of soft tissue injuries, and muscle injuries are the primary cause of physical disability. Methods: The current literature review was designed between October 2021 and April 2022, according to the PRISMA standards, using the PubMed, Scopus, and Web of Science databases. At the screening stage, we eliminated articles that did not fit into the themes developed in all subchapters of the study (n = 70), articles that dealt exclusively with orthopaedics (n = 34), 29 articles because the articles had only the abstract visible, and 17 articles that dealt exclusively with other techniques for the treatment of musculoskeletal disorders. The initial search revealed 343 titles in the databases, from which 56 duplicate articles were automatically removed, and 2 were added from other sources. Results: The combination of these three techniques results in the following advantages: It increases joint mobility, especially in stiff joints, it increases the range of motion, accelerates tissue repair, improves tissue stability, and extensibility, and it reduces soft tissue inflammation (manual therapy). In addition, it decreases the concentration of pro-inflammatory mediators and improves capillary permeability, resulting in the total eradication of inflammation (HILT). It warms the deep tissues, stimulates vascularity, promotes the repose of tissues (particularly muscle tissue), and stimulates drainage (TECAR). Conclusions: TECAR therapy, combined with manual therapy and High-Intensity Laser therapy in treating muscle diseases, presented optimal collaboration in the recovery process of all muscle diseases.

Photothermal Effects of High-Intensity Laser Therapy on the Superficial Digital Flexor Tendon Area in Clinically Healthy Racehorses

The aim of the present study was to assess the photothermal effects of high-intensity laser therapy (HILT) on the superficial digital flexor tendon (SDFT) of the hindlimb in racehorses. It was conducted on 18 clinically healthy thoroughbreds that were subjected to thermographic examination to measure surface temperature changes in the SDFT. This was performed before and immediately after HILT. This revealed statistically significant differences in the temperature of the skin surface overlying the flexor tendons (p < 0.001). The surface temperature of the area examined was higher by an average of 3.5 °C after HILT, compared with the temperature measured before HILT. Our results prove that HILT has a photothermal effect in treating soft tissue. This finding can be helpful in determining the appropriate parameters for monitoring the short- and long-term effects of HILT.

The Comparison of The Efficacy of Photobiomodulation and Ultrasound in the Treatment of Chronic Non-specific Neck Pain: A Randomized Single-Blind Controlled Trial

Introduction: Chronic neck pain is a common complaint among office workers. The aim of the present study was to compare the efficacy of a high-intensity laser and physiotherapy in office workers who were diagnosed with chronic non-specific neck pain. Methods: This study was a single-blind randomized controlled trial, with parallel allocation. Sixty office workers with chronic neck pain, aged between 25 and 55 years, participated in the study. The participants were randomly divided into two groups: photobiomodulation (by a high-level laser) and physiotherapy. Visual analogue scale (VAS), Neck Disability Index (NDI), Neck Pain and Disability Scale (NPDS) and Bournemouth Questionnaire (BQN) were completed on three occasions (before, immediately and 2 weeks after the intervention) to assess and compare the efficacy of the high-intensity laser and physiotherapy in neck pain. Data were analyzed by SPSS 23 software using the chi-square test, Student's t test, multivariate tests, and Fisher's exact test. Results: The mean age of the participants was 37.53±9.52 and 41.16±7.85 years in physiotherapy and laser therapy respectively. The VAS score and NDI scores decreased after both kinds of interventions, and the effect of photobiomodulation was significantly higher than physiotherapy (P < 0.001). Both treatment modalities significantly affect different aspects of chronic neck pain assessed by NDPS and BQN questionnaires and the effect of photobiomodulation was more prominent than physiotherapy. Conclusion: The findings of this study showed that photobiomodulation and physiotherapy can reduce chronic neck pain and its different aspects and the effect of laser therapy was significantly higher than physiotherapy.

Chinese Association for the Study of Pain: Expert consensus on diagnosis and treatment for lumbar disc herniation

Lumbar disc herniation is a common disease in the clinical context and does great harm to either the physical or mental health of patients suffering from this disease. Many guidelines and consensus for the diagnosis and treatment of lumbar disc herniation have been published domestically and internationally. According to the expert consensus, clinicians could adopt tailored and personalized diagnosis and treatment management strategies for lumbar disc herniation patients.

The effectiveness of high intensity laser therapy in the patients with lumbar disc herniation: A protocol of randomized placebo-controlled trial

BACKGROUND

There is no consensus in existing literature on the pulse power, application time, frequency and the dose of energy of laser therapy for the patients. Therefore, we conducted this research for the assessment of safety and efficiency of ultrasound and high-intensity laser therapy (HILT) in the lumbar disc herniation (LDH) patients.

METHODS

Our present research was approved by the institutional review board in the West China-Guangan Hospital. All the participants would acquire the written informed consent. From December 2020 to December 2021, we will conduct a prospective evaluation via a senior surgeon for 1 hundred LDH patients who plan to undergo the conservative treatment at our hospital. In this research, the inclusion criteria contained: the patients with lumbar disc herniation diagnosed by lumbar MRI; the patients with no history of trauma or congenital abnormalities; and the patients with sufficient psychological ability to understand and then answer the questions raised in assessment scale. The participants were randomly divided into the control group or HILT group after performing the examination of baseline. The main outcome was the pain score of visual analog scale. The other results contained the adverse effects, back range of motion as well as functional scores.

CONCLUSIONS

We assumed that the HILT is as effective as the ultrasound therapy in treating pain for LDH.

Short-wave diathermy in the clinical management of musculoskeletal disorders: a pilot observational study

Musculoskeletal disorders are the most common cause of pain and functional limitation in the general population. The study aim was  to evaluate short-wave diathermy (SWD) effects on pain and quality of life in people with musculoskeletal disorders. Eighty participants (31 men, mean age 56 ± 12.49 years) were enrolled, recruiting from outpatient clinics at the Rehabilitation Unit, University Hospital, Padova. Inclusion criteria were pain lasting more than 15 days, pain visual analog scale (VAS) score higher than 50/100 mm, and a diagnosis of osteoarthritis, neck/back pain, or tendinopathies. All participants underwent ten sessions of percutaneous SWD, 3 times/week. Each session lasted 15-20 min, with frequencies of 4 or 8 MHz and heat intensity between 40 and 60 W. Outcomes were assessed before and after treatment. Primary outcome was pain reduction, evaluated by short form McGill pain questionnaire, which includes VAS and present pain intensity (PPI). Secondary outcome was improvement in social and work-related activity limitations. Participants were grouped based on classification of pain [nociceptive and neuropathic pain (group A) vs nociceptive only (group B)]. VAS and PPI improved significantly (p < 0.01). No difference in pain reduction (VAS and PPI) emerged between the groups. Limitations due to pain in work-related and non-work-related activities decreased (p < 0.01); use of pain medications was reduced at T1 vs T0 (p < 0.01). Our results suggest that SWD is effective in reducing musculoskeletal pain in the short term, providing relief and improving quality of life.

The effectiveness of high intensity laser therapy in the management of spinal disorders: A systematic review and meta-analysis

BACKGROUND

Spinal disorders are common health problems which include wide categories of diseases that affect the spinal soft tissues, joints and bone.

OBJECTIVE

The aim of this systematic review was to evaluate the effectiveness of high intensity laser therapy (HILT) on pain and function in patients with spinal disorders.

METHODS

Six databases were searched up to the end of February 2018 including PubMed, MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), Open Grey and Grey Literature Report. In addition, the reference lists of all included studies were searched for any relevant studies. PEDro scale and GRADE system were performed to assess the quality of the studies. A meta-analysis was conducted to calculate the overall effect size.

RESULTS

A total of ten randomised controlled trials (RCTs) met the inclusion criteria, with four studies of the efficacy of HILT on neck pain (NP) and six on low back pain (LBP). According to the PEDro scale assessment, only two studies were rated as high quality, while the remainder were rated as fair or low quality. Forest plots showed that HILT with exercise was significantly more effective than placebo HILT with exercise in terms of pain reduction (SMD -1.11; 95% CI -1.42 to -0.80; P< 0.00001; I2 0%) and functional improvement (SMD -1.03; 95% CI -1.33 to -0.72; P< 0.00001; I2 0%). Meta-analyses also showed that HILT alone or HILT with conventional physiotherapy (CPT) significantly provided better outcomes than CPT alone.

CONCLUSIONS

HILT is considered as a complementary modality for pain reduction and function improvement in patients with spinal disorders. However, the quality of the body of evidence was rated from 'very low' to 'low' quality. Further high quality trials are required for standardisation of irradiation parameters and the treatment protocol to establish the efficacy of HILT for spinal disorders.

The Beneficial Effects of High-Intensity Laser Therapy and Co-Interventions on Musculoskeletal Pain Management: A Systematic Review

Introduction: High-intensity laser therapy (HILT) has been used more recently in the therapeutic protocols of pain managements. Adding therapeutic interventions to laser therapy is usual in clinical practice. This study aimed to evaluate the efficacy of HILT and beneficial effects of adding cointerventions to HILT in musculoskeletal pain management. Methods: The following databases were searched up to August 2018: Medline, PubMed, EMBASE, Cochrane, Google Scholar, Springer and ISI. The keywords of pain, HILT, high power laser therapy, laser therapy, photobiomodulation, physical therapy and rehabilitation were searched. The quality of the articles was assessed using the PEDro scale. The primary measure was pain severity expected to be reported in all studies. Effect size was calculated as standardized mean differences divided by the standard deviation of either the treatment or other group. Results: Initially 52 potential studies were found. Eighteen of these studies were excluded based on title and abstract. The full text of 34 remaining articles was screened and 15 of the studies were excluded. All included studies had high quality (PEDro ≥7). Approximately, 94% of included articles (n=18) revealed positive effects of HILT on pain. The effect sizes for HILT and placebo/comparator groups were 0.9-9.11 and 0.21-11.22 respectively. Also, the differences of effect size between two groups were between 0.03 to 5.85. Conclusion: It is early to determine that HILT may be an effective non-invasive agent in the management of musculoskeletal pain, as few studies have shown its clinical efficacy. Adding related co-interventions to HILT may enhance the beneficial effects of laser therapy. The variability of the study methods and outcomes suggests that further long-term follow-up, randomized controlled clinical trials with appropriate methodological design are needed regarding the effectiveness of HILT on pain.

Effect of laser treatment on postural control parameters in patients with chronic nonspecific low back pain: a randomized placebo-controlled trial

The management of nonspecific lumbar pain (NSLP) using laser irradiation remains controversial. A systematic review of recently published studies indicates that the effects of laser therapy are commonly assessed using only imperfect methods in terms of measurement error. The main objective of this study was to assess static postural stability using an objective tool in patients with chronic NSLP after laser irradiation at different doses and wavelengths. In total, 68 patients were included in the laser sessions and were randomly assigned into four groups: high-intensity laser therapy at 1064 nm and 60 J/cm2 for 10 min (HILT), sham (HILT placebo), low-level laser therapy at 785 nm and 8 J/cm2 for 8 min (LLLT), and sham (LLLT placebo). In addition, all patients were supplemented with physical exercises (standard stabilization training). To assess postural stability, a double-plate stabilometric platform was used. All measurements were performed pre- and post-laser sessions (three weeks) and at follow-up time points (one and three months). Laser procedures led to more balanced posture stability in patients, although these positive changes were significant mainly for short-term observation (after 4-week therapy). In the follow-up analysis, the parameters were gradually impaired. Kruskal-Wallis analysis of variance (ANOVA) for independent variables did not show any difference between the studied groups. Low- and high-intensity laser therapy does not lead to a significant improvement in postural sway in patients with NSLP compared with standard stabilization training based on short- and long-term observations.

Photobiomodulation using high- or low-level laser irradiations in patients with lumbar disc degenerative changes: disappointing outcomes and remarks

Background

Laser therapy seems to be a beneficial physical agent for chronic low back pain (LBP), and it is commonly used in the clinical rehabilitation practice. However, there are still no indisputable and clearly defined protocols and practical guidelines, and further, the methodology of the previous reports leaves many unsatisfied and raises some reservations.

Objective

The aim of this study was to evaluate the effectiveness of low-level laser therapy (LLLT) and high-intensity laser therapy (HILT) in patients with lumbar disc degenerative changes based on the analysis of the short- and long-term results and in comparison with the placebo effect.

Design

This study was a prospective and placebo-controlled clinical trial.

Materials and methods

A group of 68 participants were qualified for the therapy and were assigned to four comparative groups in the order they volunteered: HILT of 1,064 nm, 60 J/cm², 10 minutes (HILT); sham (HILT placebo); LLLT of 785 nm, 8 J/cm², 8 minutes; and sham (LLLT placebo). The following tests were used to assess the effectiveness of treatment: 1) the visual analogue scale; 2) the Laitinen Questionnaire Indicators of Pain; 3) the Oswestry Disability Index; 4) the Roland–Morris Disability Questionnaire; 5) Lasegue test; and 6) Schober’s test. All measurements were carried out before and after irradiations (3 weeks) and in follow-ups (1 and 3 months).

Results

After applying verum or placebo laser irradiation, therapeutic progress was observed in all comparative groups; however, no statistically significant differences were observed among the procedures.

Conclusion

The high- and low-energy laser therapy methods used in the present article are ineffective in relation to patients with lumbar disc degenerative changes in both the short- and long-term perspectives and do not show a significant advantage over the placebo effect.

Comparison of high-intensity laser therapy and combination of transcutaneous nerve stimulation and ultrasound treatment in patients with chronic lumbar radiculopathy: A randomized single-blind study

Objective:

To compare the effects of high-intensity laser therapy (HILT) and a combination of transcutaneous nerve stimulation (TENS) with ultrasound (US) therapy on pain and functionality in patients with chronic lumbar radiculopathy.

Methods:

This prospective randomized comparative study was conducted in Department of physical medicine and rehabilitation, Turgut Ozal Medicine Center, Malatya, Turkey from April 2016 to September 2016. A total of 54 patients with chronic lumbar radiculopathy were enrolled in this study. The patients were randomly divided into two groups: Group 1 (n:27) received 10 sessions of a combination of hot pack, TENS, US and exercise, and Group 2 (n:27) received hot pack, HILT and exercise. The outcomes measured were low back with unilateral leg pain level measured by visual analog scale (VAS) and functionality measured with the Oswestry Disability Index (ODI) at the end of the therapy and four weeks later. p-value less than 0.05 considered statistically significant.

Results:

In two groups, VAS (low back with unilateral leg pain) and ODI scores showed significant changes. At the end of the 2 weeks intervention, participants in Group-1 showed a significantly greater decrease in pain than participants in Group-2. Statistically significant differences in pain variation and functionality (VAS and ODI) were observed four weeks after treatment sessions for participants in the TENS+US therapy group compared with participants in the HILT group.

Conclusion:

HILT and TENS+US combined with exercise were effective treatment modalities in decreasing the VAS and ODI scores. TENS+US combined with exercises were more effective than HILT combined with exercise.

Comparison of the effectiveness of two physiotherapy programs for female patients with lumbar spine discopathy

Background. Lower back pain is one of the most common problems in the human body relat-ed to the disturbances of the motor organ’s structure and function. It challenges contemporary physiotherapy which aim is to reduce or, when possible, eliminate pain, restore fitness for eve-ryday life and prevent recurrences. The aim of the study was to compare two physiotherapy programmes in terms of lowering pain intensity, improvement of lumbar and thoracolumbar spine mobility, as well as functional ability in females with lumbar spine discopathy. Material and methods. The study included 100 women aged 45-50 with lumbar spine disco-pathy being treated in outpatient conditions. The patients were divided into two 50-subject groups depending on the programme used. The physiotherapy programme for group I patients included classic massage, kinesiotherapy and interferential currents, and in group II: classic massage, kinesiotherapy and ultrasound. The research tool was the Numeric Pain Rating Scale (NRS), the Roland Morris Disability Questionnaire (RMDQ) and measurements of lumbar and thoracolumbar spine mobility. The Wilcoxon and Mann-Whitney U tests were used for the analysis. Results. After completion of the physiotherapy programme, the women in group I experi-enced significantly lower pain (p=0.037) and higher functional efficiency (p=0,001). The range of improvement, assessed by the difference in the results of study II and III, was signif-icantly higher for the II group of women (p=0,002). One month after completion of therapeu-tic treatment, there were no statistically significant differences between the groups (p=0,169, p=0,067). Conclusions. The use of interferential currents in the physiotherapy of individuals with lum-bar spine discopathy compared to ultrasound therapy allows for greater improvement in reduc-ing pain intensity, lumbar and thoracolumbar spine mobility, as well as higher functional effi-ciency. The effectiveness of ultrasound had increased over time since the end of therapy and only after one month in the case of both physiotherapy programmes, similar effects could be observed.

Use of electroanalgesia and laser therapies as alternatives to opioids for acute and chronic pain management

The use of opioid analgesics for postoperative pain management has contributed to the global opioid epidemic. It was recently reported that prescription opioid analgesic use often continued after major joint replacement surgery even though patients were no longer experiencing joint pain. The use of epidural local analgesia for perioperative pain management was not found to be protective against persistent opioid use in a large cohort of opioid-naïve patients undergoing abdominal surgery. In a retrospective study involving over 390,000 outpatients more than 66 years of age who underwent minor ambulatory surgery procedures, patients receiving a prescription opioid analgesic within 7 days of discharge were 44% more likely to continue using opioids 1 year after surgery. In a review of 11 million patients undergoing elective surgery from 2002 to 2011, both opioid overdoses and opioid dependence were found to be increasing over time. Opioid-dependent surgical patients were more likely to experience postoperative pulmonary complications, require longer hospital stays, and increase costs to the health-care system. The Centers for Disease Control and Prevention emphasized the importance of finding alternatives to opioid medication for treating pain. In the new clinical practice guidelines for back pain, the authors endorsed the use of non-pharmacologic therapies. However, one of the more widely used non-pharmacologic treatments for chronic pain (namely radiofrequency ablation therapy) was recently reported to have no clinical benefit. Therefore, this clinical commentary will review evidence in the peer-reviewed literature supporting the use of electroanalgesia and laser therapies for treating acute pain, cervical (neck) pain, low back pain, persistent post-surgical pain after spine surgery (“failed back syndrome”), major joint replacements, and abdominal surgery as well as other common chronic pain syndromes (for example, myofascial pain, peripheral neuropathic pain, fibromyalgia, degenerative joint disease/osteoarthritis, and migraine headaches).

Experimental Verification of Modeled Thermal Distribution Produced by a Piston Source in Physiotherapy Ultrasound

Objectives. To present a quantitative comparison of thermal patterns produced by the piston-in-a-baffle approach with those generated by a physiotherapy ultrasonic device and to show the dependency among thermal patterns and acoustic intensity distributions. Methods. The finite element (FE) method was used to model an ideal acoustic field and the produced thermal pattern to be compared with the experimental acoustic and temperature distributions produced by a real ultrasonic applicator. A thermal model using the measured acoustic profile as input is also presented for comparison. Temperature measurements were carried out with thermocouples inserted in muscle phantom. The insertion place of thermocouples was monitored with ultrasound imaging. Results. Modeled and measured thermal profiles were compared within the first 10 cm of depth. The ideal acoustic field did not adequately represent the measured field having different temperature profiles (errors 10% to 20%). Experimental field was concentrated near the transducer producing a region with higher temperatures, while the modeled ideal temperature was linearly distributed along the depth. The error was reduced to 7% when introducing the measured acoustic field as the input variable in the FE temperature modeling. Conclusions. Temperature distributions are strongly related to the acoustic field distributions.

Effectiveness of High-Intensity Laser Therapy in Subacromial Impingement Syndrome

OBJECTIVE

The short-term effectiveness of high-intensity laser therapy (HILT) was investigated as a retrospective case series for the treatment of the pain and disability associated with subacromial impingement syndrome (SAIS).

MATERIALS AND METHODS

A total of 42 patients, who were diagnosed with subacromial impingement syndrome, underwent a total of nine sessions (three sessions per week) of high-intensity laser therapy. The patients were evaluated before therapy and 8 weeks after therapy using the pain and disability subscales and the total scores of the Shoulder Pain and Disability Index (SPADI), as well as scores for the University of California at Los Angeles (UCLA) shoulder rating scale.

RESULTS

Significant differences were observed between SPADI pain, disability, and total scores and UCLA scores of the patients.

CONCLUSIONS

HILT was found to be effective in the short term in the treatment of pain and disability in patients with SAIS.
