Effectiveness of photobiomodulation therapy in the treatment of patients with an ankle sprain: a systematic review and meta-analysis.

BACKGROUND: Photobiomodulation therapy (PBMT) is widely used in the treatment of patients with musculoskeletal and sports disorders with a lack of significance in patients with sprain ankle. PURPOSE: This review investigated the effect of PBMT on pain, oedema, and function in patients with an ankle sprain. METHODS: A systematic search of the databases (MEDLINE, PubMed, EBSCO, Web of Science, Wiley Online Library, Science Direct, Physiotherapy Evidence (PEDro), and the Cochrane Databases) was performed from inception to the end of 2023 to identify any clinical study investigating the effect of PBMT on ankle sprain. PBMT parameters and measured outcomes were extracted. The primary measured outcome was pain and function, and oedema were secondary measured outcomes. Methodological quality was assessed using the PEDro scale. The level of evidence was determined by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. A random effect meta-analysis with forest plot was used to calculate standardized mean difference (SMD) at a 95% confidence interval and the overall effect size (ES). RESULTS: Six studies (598 patients) were included in the review and five studies in the meta-analysis. There were two fair-quality and four good-quality studies, with a moderate level of evidence on pain, and a low level of evidence on oedema and function. The meta-analysis revealed a significant overall effect of PBMT on pain with high ES [SMD - 0.88 (-1.76, -0.00), p = 0.05], with a non-significant effect on oedema and function with a medium ES [SMD - 0.70 (-1.64, 0.24), p = 0.14] on oedema and low ES on function [SMD - 0.22 (-0.69, 0.24), p = 0.35]. Significant heterogeneity was observed in all measured outcomes with high heterogeneity (I2 > 75%) in pain and oedema and moderate heterogeneity in function. CONCLUSION: PBMT is quite effective for patients with an ankle sprain. PBMT showed high effect size with a moderate level of evidence on pain intensity. The lack of significant effects of PBMT on function and edema with low level of evidence limit the confidence to the current results and recommend further large high-quality studies with higher PBMT intensity and fluency for standardisation of the irradiation parameters and treatment protocol.

Investigating behavior, attitudes, knowledge, awareness and barriers to the implementation of evidence-based practice by physiotherapists in Egypt: A cross sectional study.

Few studies exist regarding the attitudes and behaviours of Egyptian physiotherapists in relation to the use of evidence in practice (EBP). The purpose of this study was to describe the beliefs, attitudes, knowledge, and behaviours of Egyptian physical therapists as they relate to evidence-based practice. It also explores their perception of possible barriers to implement EBP. Four hundred and seventy Egyptian therapists responded to our questionnaire with results revealing participants' awareness towards EBP was quite diverse. Only terms of systematic review and randomized controlled trial were well understood while remaining terms showed various level of comprehension which were rather low. Results also revealed significant correlations between attitudes towards EBP and overall awareness as well as attitudes and knowledge (r = 0.270 and 0.107) respectively. In addition, a significant relationship was also found between EBP awareness and knowledge with (r = 0.219). With regards to the barriers, insufficient teaching in previous education was identified as the primary barrier (34.4 %), followed by lack of funding and resources (31.1 %), while lack of time (10.2 %) was reported as the least. These barriers highlight the need to enhance implementation of EBP within Egyptian Physiotherapists. Findings of this study can be used as a foundation for the implementation of EBP in various clinical settings by understanding the limitations and barriers reported. Our study concluded that despite Egyptian physiotherapists declare their awareness of EBP, nevertheless, knowledge is restricted to a small number of terms. More focus is required to enhance the knowledge and practice of EBP. Focusing on adjustable factors, including increasing the awareness of value of research would help reduce time and resource demands for physiotherapists when implementing EBP.

Effect of dancing on freezing of gait in patients with Parkinson's disease: A systematic review and meta-analysis.

BACKGROUND: Freezing of gait (FOG) is one of the major debilitating motor symptoms that affect Parkinson's disease (PD) patients' gait,OBJECTIVE:To investigate the effect of dancing on FOG, motor symptoms, and balance in patients with Parkinsonism. METHODS: Eight databases were searched for full-text English randomized control trials (RCTs). The freezing of gait (FOG) was the primary outcome while the balance and Unified Parkinson Disease Rating Scale (UPDRS-3) were the secondary outcomes. Methodological quality was evaluated by the Physiotherapy Evidence Database (PEDro) scale. Level of evidence was assessed by Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. A random-effect model of meta-analysis was used to calculate the standardized mean difference (SMD) at a 95% confidence interval (CI), and the effect size. RESULTS: A total of nine studies (263 patients) were included. Qualitative data related to participants, dancing type, measured outcomes, and follow-up were extracted. PEDro scale showed one fair-quality and eight high-quality studies. GRADE showed a low to very low level of evidence with moderate effect size on both UPDRS (SMD -70 [-1.04, -0.36]) and Balance (SMD 0.35 [0.08, 0.63]). CONCLUSION: Dance is an effective modality on improving UPDRS and balance with small effect on FOG. Further high-quality studies with high-quality of evidence are recommended to increase the confidence to the effect estimate and support the finding results.

Cross-cultural Adaptation and Validation of the Arabic version of Stroke Self-Efficacy Questionnaire for Patients with Stroke.

BACKGROUND: Self-efficacy has an important impact on rehabilitation outcomes in stroke. The Stroke Self-Efficacy Questionnaire assesses performance in daily functional activities and self-management following a stroke. PURPOSE: To translate and cross-culturally adapt the Stroke Self-Efficacy Questionnaire (SSEQ) into the Arabic language and to assess its psychometric properties among patients with stroke. METHODS: SSEQ was translated into Modern Arabic and then translated back into English. An expert review panel produced a pre-final version of SSEQ-AR, which was followed by a pilot test with a sample of 15 patients with stroke. The psychometric properties of the final version of the SSEQ-AR were evaluated in 135 patients with stroke. DATA ANALYSIS: Cronbach's alpha and ICC were calculated to describe the internal consistency and test-retest reliability, respectively. Short-Form Survey (SF-12) physical and mental subscales and Fall Efficacy Scale International were used to determine the construct validity. RESULTS: The total score of the SSEQ-AR and subscales showed a strong to very strong (ICC2,1 0.89-0.92), and acceptable internal consistency for two subscales (Cronbach's alpha = 0.81 to 0.94) and total (Cronbach's alpha = 0.93). The SSEQ-AR subscales showed a good correlation with physical component subscales of SF-12 (r = 0.64-0.72) and excellent correlation with FES-I in total (r = 0.82) and with subscales (r = 0.75-0.79). CONCLUSION: This study shows that SSEQ-AR is a reliable and valid instrument that assesses the level of self-efficacy for patients with stroke in Arabic-speaking countries.

Effectiveness of Photobiomodulation Therapy in the Treatment of Myofascial Pain Syndrome of the Upper Trapezius Muscle: A Systematic Review and Meta-Analysis.

Objective: This systematic review aimed to investigate the efficacy of photobiomodulation therapy (PBMT) on pain and pressure pain threshold (PPT) in patients with myofascial pain syndrome (MPS) of the upper trapezius muscle. Materials and methods: A total of 17 studies (944 patients) were included; data regarding participants, intervention parameters, outcome measures, time of measurement, and follow-up were extracted. Evaluation of the methodological quality was performed by Physiotherapy Evidence Database (PEDro) scale. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the quality of evidence. A meta-analysis was performed on 16 studies, and standardized mean difference (SMD), corresponding 95% confidence interval (CI), and overall effect size (ES) were calculated. Results: Meta-analysis using a random-effect model was performed to evaluate the effects of PBMT alone or PBMT plus exercise (EX) compared with placebo, medical treatment, physical therapy (PT) modality, manual therapy, or complementary PT. Assessment according to the PEDro scale revealed 12 high-quality, 3 fair-quality, and 2 low-quality studies. According to the GRADE system, studies exhibited low to medium quality of evidence, with medium ES [SMD -0.54 (95% CI -1.05 to -0.02)] for studies using PBMT alone and large ES [SMD -0.80 (95% CI -1.35 to -0.26)] for PBMT+EX. Conclusions: The present systemic review revealed that PBMT is an effective PT modality for reducing pain and increasing PPT in patients with MPS of the upper trapezius. PBMT, when combined with EX, had more significant effects in reducing pain and increasing PPT compared with controls. The low-quality studies with low to moderate quality of evidence limit the confidence in the effect estimate and recommend further high-quality studies for standardization of treatment protocols and irradiation parameters.

The Effectiveness of Perturbation-Based Training in the Treatment of Patients With Stroke: A Systematic Review and Meta-Analysis.

Purpose: To investigate the effectiveness of perturbation-based training (PBT) on balance and balance confidence in patients with stroke. Methods: Systematic searching was performed from inception to November 2021. The inclusion criteria were RCTs assessed the effectiveness of PBT in patients with stroke. Data regarding participants, intervention parameters, outcome measures, follow-up, and main results were extracted. The outcomes were balance and balance confidence. Methodological quality and quality of evidence were assessed using the Physiotherapy Evidence Database (PEDro) scale and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system; respectively. Data analysis: A total of 7 articles )271 patients) were included. A meta-analysis using a random-effect model was performed on 6 studies. Standardized mean difference (SMD) with a 95% confidence interval was calculated for balance and balance confidence. Results: PEDro scale revealed 5 good-quality and 2 fair-quality studies. The currently available evidence showed significant effect of PBT in improving balance (SMD 0.60 [95% CI 0.15-1.06]; P = .01; very low-quality evidence) and non-significant in improving balance confidence (SMD 0.11 [95% CI -0.24 to 0.45]; P = .55; low-quality evidence). Conclusion: PBT may improve balance in patients with stroke, however its effect on balance confidence was limited. The quality of the evidence was low or very low with little confidence in the effect estimate, which suggests further high-quality trials are required. Registration: PROSPERO registration number (CRD42021291474).

Effectiveness of multiwave locked system laser on the treatment of patients with idiopathic Bell's palsy: a randomized double-blind placebo controlled trial.

The objective of this study is to investigate the effect of scanning and point application of multiwave locked system (MLS) laser therapy on the recovery of patients with idiopathic Bell's palsy (IBP). A randomized double-blind placebo-controlled trial was carried out on 60 patients with subacute BP. Patients were randomly assigned into three groups of 20 patients each. Facial massage and facial exercises were applied to all patients. Group one received MLS laser as a manual scanning technique (10 J/cm2, area 50cm2, total energy 500 J). Group two received MLS laser using point application technique (10 J/point, 8 points, total 80 J). Group three received placebo laser. House-Brackmann scale (HBS) and facial disability index (FDI) were used to evaluate the facial recovery. Assessment was performed at baseline and after 3 and 6 weeks of treatment. Comparison within and between groups was performed statistically with significance level p < 0.05. Results showed significant improvement in the FDI and HBS after treatment in all groups. Both scanning and point application significantly improved the score of FDI and HBS more than placebo group. Scanning technique combined with facial massage and exercises had a more significant effect than the point application group or the placebo group in improving FDI and HBS scores after 3 and 6 weeks of treatment. The MLS laser is an effective physiotherapy method used for the treatment of patients with IBP. MLS laser in scanning or point application techniques was more effective than exercise alone with greater effect of scanning technique than point application technique.

The Effectiveness of Telerehabilitation on Balance and Functional Mobility in Patients with Stroke: A Systematic Review and Meta-Analysis.

Objective: The aim of this systematic review and meta-analysis was to investigate the effectiveness of telerehabilitation on improving balance and functional mobility in stroke survivors. Methods: Comprehensive searching was conducted from inception to May 2022. The inclusion criteria were studies evaluating the effectiveness of telerehabilitation in stroke survivors. Data regarding participants, intervention, outcome measures, and main results were extracted. PEDro scale and the Grading of Recommendations Assessment Development and Evaluation (GRADE) were used to assess the methodological quality and quality of evidence, respectively. Data Analysis: A total of fourteen articles) 594 patients) were included. A meta-analysis using a random-effect model was performed on thirteen studies )530 patients). Standardized mean difference (SMD) with 95% confidence interval (CI) was calculated for balance and functional mobility. Results: PEDro scale revealed ten good-quality studies, three fair-quality studies, and one poor-quality study. According to the available evidence, telerehabilitation has a small effect size in improving both balance (SMD 0.33 [95% CI 0.03 to 0.63]; P =0.03; low quality of evidence) and functional mobility (SMD 0.27 [95% CI 0.02 to 0.52]; P =0.03; low quality of evidence). Conclusion: Telerehabilitation may improve balance and functional mobility in stroke survivors. However, it is evident that more high-quality research is required due to the existence of low to very low-quality evidence with limited confidence in the effect estimate.

Effects of low-level laser therapy versus soft occlusive splints on mouth opening and surface electromyography in females with temporomandibular dysfunction: A randomized-controlled study.

BACKGROUND: Low level lasers have been used as an alternative pain relief therapy for muscle and joint pain, since it induces analgesic, anti-inflammatory, and biomodulation effects of the physiological cell functions. The effectiveness of low-level laser therapy in temporomandibular joint dysfunction (TMD) treatment, however, is not well established. Although Surface electromyography (sEMG) has been suggested as a complementary means in TMD diagnosis, the effect of conservative treatments on muscle activity has not yet been thoroughly correlated with (sEMG) findings. PURPOSE: To assess the efficacy of low-level laser therapy (LLLT) as compared to occlusive splint therapy (OST) on the TMJ opening index (TOI) and sEMG of masticatory muscles. MATERIALS AND METHODS: 112 female subjects suffering from unilateral myogenous TMD, aged 21-30 years-old, were recruited and divided into three groups: LLLT; soft occlusive splint therapy OST and a waitlist group as controls. OUTCOME MEASURES: TMJ opening index (TOI), Visual analogue scale (VAS), surface electromyography (sEMG). RESULTS: A significant reduction was reported in TOI, VAS and the sEMG within the LLLT and OST groups as well as significant decrease in all outcomes between groups in favor of the LLLT group (P< 0.0001). Meanwhile, there was a weak significant difference within the control group probably attributed to the analgesic. Post-hoc pairwise comparisons between groups [control vs occlusive splints, control vs low-level laser and low-level laser vs occlusive splints] revealed significant differences in the VAS and TOI [P = 0.0001; 95% CI: 0.9-2.2, 1.61-4.01, 0.65-1.96]. CONCLUSIONS: Findings support an evident short term therapeutic effect of the LLLT on improving VAS, TOI and sEMG in females suffering from myogenous TMD.

Efficacy of multi-wave locked system laser therapy on nerve regeneration after crushing in Wister rats.

[Purpose] To investigate the efficacy of the multi-wave locked system laser therapy on the regeneration of peripheral nerve injuries by evaluating the functional, electrophysiological, and morphological changes of the crushed sciatic nerve in Wistar rats. [Materials and Methods] Sixty male Wistar rats (200-250 g) were randomly assigned to control negative, control positive, or laser groups and subjected to no laser therapy or crushing, to crushing without laser therapy, or crushing followed by multi-wave locked system laser therapy five times/week for four weeks (power=1 W, energy density=10 J/cm2, total energy=100 J), respectively. Functional, electrophysiological, and morphometric analyses were performed before and 7, 15, 21, and 28 days after crushing. The sciatic functional index, compound motor action potential amplitude, motor nerve conduction velocity, and nerve and myelin sheath diameters were measured. [Results] The sciatic functional index value decreased significantly, while the compound motor action potential amplitude, motor nerve conduction velocity, nerve diameter, and myelin sheath diameter increased significantly in the laser group post-treatment compared to the values in the control groups. [Conclusion] Multi-wave locked system laser therapy was effective in accelerating the regeneration of crushed sciatic nerves in Wistar rats.

Pulsed ND:YAG laser combined with progressive pressure release in the treatment of cervical myofascial pain syndrome: a randomized control trial.

[Purpose] To investigate the effect of pulsed Nd:YAG laser combined with the progressive pressure release technique (PPRT) and exercises in the treatment of myofascial trigger points (MTrPs) in patients with myofascial pain syndrome (MPS). [Participants and Methods] A total of 50 patients with MTrPs in the upper trapezius muscle participated in the study. The patients were randomly assigned to two groups and treated with laser plus PPRT (Laser + PPRT group) or placebo laser and exercises (PL + PPRT group). The laser was applied for eight MTrPs with a 50 J/point. PPRT was applied for 30 seconds for each point. Exercises included strengthening and stretching exercises applied three times per week for four weeks. A visual analogue scale (VAS) and pressure pain threshold (PPT) were used to measure pain and pain threshold, respectively. A cervical range of motion device (CROM) was used to measure the cervical range of motion. [Results] Both treatment groups showed significant improvement in CROM, PPT, and VAS post-treatment with a more significant effect in the Laser + PPRT group compared to the PL + PPRT group. [Conclusion] PPRT and exercises alone or that in combination with laser therapy were effective in the treatment of active MTrPs in patients with MPS.

Dose-dependent effect of the pulsed Nd:YAG laser in the treatment of crushed sciatic nerve in Wister rats: an experimental model.

The objective of the study was to investigate the efficacy of three energy densities 4, 10, and 50 J/cm2 of pulsed Nd:YAG laser for the treatment of crushed sciatic nerve in Wister rats by evaluating changes in the sciatic functional index and the electrophysiology.A total of 180 Wistar rats were involved in the study. Rats were randomly assigned to five groups. Rats were subjected to the sciatic nerve crushing. Control negative (CONT-ve), which received no crushing; control positive (CONT+ve), which received crushing with no laser; and HILT-4, HILT-10, and HILT-50 groups, which received pulsed Nd:YAG laser (10 Hz, 360 mJ/cm2) with energy densities 4, 10, and 50 J/cm2, respectively. The SFI, the amilitude of compound motor action potential (CMAP) and sciatic motor nerve conduction velocity (MNCV) were measured before and after seven, 14, and 21 days after crushing. For the SFI and electrophysiological analysis, repeated measures ANOVA is used, followed by Bonferroni's repeated-measures test. Statistical significance was set at p < 0.05. After one week, there was no significant difference in SFI, CMAP, and MNCV among the three laser groups with significant changes between them and CONT-ve and CONT+ve groups. There was a significant increase in either CMAP amplitude or MNCV after 14 days with significant decrease in the SFI after 21 days among all treatment groups. The pulsed Nd:YAG laser applied with energy densities 4, 10, and 50 J/cm2 significantly decreased the SFI and increased the CMAP and MNCV of the crushed sciatic nerve in Wister rats. Among laser doses, the difference in the rate of recovery in the electrophysiology was found after two weeks while in the SFI after three weeks. The improvement after the nerve injury was time and dose dependent.

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.

Changes in local skin temperature after the application of a pulsed Nd:YAG laser to healthy subjects: a prospective crossover controlled trial.

Pulsed Nd:YAG laser (1064 nm) is a recent modality that is used for the rehabilitation of musculoskeletal disorders, but there is no evidence about its thermal effects. The aim of the study was to investigate the changes in local skin temperature (LST) after the application of a pulsed Nd:YAG laser to healthy subjects. The study participants were 30 male subjects with an average age of 21.96 (± 0.92) years. A rectangular area (15 × 10 cm2) was marked at the front of the dominant thigh and scanned with a laser beam at 3000 J with 20 J/cm2 for 15 min. The other thigh was considered as a control side. The minimum, average, and maximum LSTs were measured using a thermographic camera. The measurements were performed before laser application, immediately after, and then every minute until the LST returned to the pre-treatment value. An independent t test and repeated measures ANOVA were used to analyze the changes in LST. The level of significance was set at p < 0.05. The pulsed Nd:YAG laser significantly increased the minimum, average, and maximum LSTs in comparison with the control. The increase was significant for up to 5 min after the application, and it took 10 min to reach the baseline values. The level of increase was 1.23-4.03 °C, and the average increase was 2.6 °C. The pulsed Nd:YAG laser significantly increased the minimum, average, and maximum LSTs of the thigh area in normal subjects, and the thermal effect lasted for 5 min after application.

Efficacy of high intensity laser therapy in the management of foot ulcers: a systematic review.

[Purpose] The aim of this systematic review was to assess the efficacy of high intensity laser therapy (HILT) on wound surface area in patients with foot ulcers. [Methods] Four databases including PubMed, MEDLINE, the Cochrane library, and the Physiotherapy Evidence Database (PEDro) were searched up to the end of April 2018 to identify relevant studies. Studies were included if they met the following criteria: randomised controlled trial (RCT), assessed the efficacy of HILT in patients with foot ulcers, evaluated wound surface area, and written in English language with available full text. The PEDro scale was used to evaluate the quality of studies. [Results] A total of three RCTs met the inclusion criteria, with two studies of the efficacy of HILT in adult patients with diabetic foot ulcers and one in spina bifida children with neuropathic foot ulcers. According to the PEDro scale assessment, all three studies were rated as a fair quality. All studies found that HILT provided significantly better outcomes compared to sham laser or standard medical therapy. [Conclusion] This systematic review suggests that HILT is an effective modality for wound healing in patients with foot ulcers, but further large-scale studies are required to confirm its efficacy.

Long-Term Effect of Pulsed Nd:YAG Laser in the Treatment of Patients with Rotator Cuff Tendinopathy: A Randomized Controlled Trial.

OBJECTIVE: The purpose of the present study was to investigate the long-term effect of pulsed Nd:YAG laser on the treatment of rotator cuff tendinopathy. METHODS: Sixty patients with rotator cuff tendinopathy participated and completed the study. The mean age was 50.2 ± 3.6 years. Participants were randomly assigned to one of two groups: the control group and the treatment group. Both groups were treated with an exercise program, in addition to the pulsed Nd:YAG laser received by the treatment group and the "sham" laser received by the control group, both for three sessions per week for 4 weeks. Outcome measures included pain, assessed by the visual analog scale, and range of motion (ROM), assessed using a traditional goniometer, while the shoulder pain and disability index were used to evaluate the functional recovery of the shoulder joint. Evaluation was carried out before treatment, immediately after treatment, 3 months posttreatment, and 6 months posttreatment. Statistical analyses were used to investigate the effect of interventions and to compare the study groups' pretreatment, posttreatment, and at follow-up points. The significance level was set to p < 0.05. RESULTS: Pain was significantly decreased after treatment and at follow-up points, while ROM and shoulder functions were significantly improved after treatment and at follow-up intervals in both groups. The improvement was more significant in the treatment group than in the control group posttreatment and at follow-up intervals. CONCLUSIONS: Pulsed Nd:YAG laser combined with an exercise program seems to be more effective in the treatment of patients with rotator cuff tendinopathy than a sham laser with exercises.

Long-Term Effect of Pulsed Nd:YAG Laser in the Treatment of Children with Juvenile Rheumatoid Arthritis: A Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to evaluate the long-term impact of a pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG) laser [high-intensity laser therapy (HILT)] in the treatment of juvenile rheumatoid arthritis (JRA). MATERIALS AND METHODS: A sample of 30 children participated in this study (15 in the laser group and 15 in the placebo group), with a mean age of 10.53 ± 1.25 years. Children who were randomly assigned to the laser group received HILT thrice per week for 4 weeks, plus the exercise program. HILT scanned each knee with 600 J in two phases and 15 J to 10 points for a total of 750 J for each knee. The placebo laser group received placebo HILT plus the same exercise program. The outcomes measured in this study were the pain level by the visual analog scale (VAS) and gait parameters by the GAITRite® system. Statistical analysis was performed by ANOVA with repeated measures to compare the differences between the baseline, post-treatment, and 12-week follow-up measurements for both groups. The level of significance was set at p < 0.05. RESULTS: The VAS results significantly decreased post-treatment in the laser group relative to the placebo group and were still improved at the 12-week follow-up. Gait parameters significantly increased in the laser group after 4 weeks of treatment and after 12 weeks compared to the placebo group. CONCLUSIONS: HILT, when combined with an exercise program, appears to be more effective in children with JRA than a placebo laser procedure with exercises.

Factors affecting the extent of utilization of physiotherapy services by physicians in Saudi Arabia.

[Purpose] To investigate physicians' attitudes, opinions and experiences towards physiotherapy services as well as to identify the potential factors that may affect the extent of utilization of physiotherapy services (based on physicians' beliefs) in Saudi Arabia (SA). [Subjects and Methods] A cross-sectional study was conducted. [Results] A total of 108 respondents met the inclusion criteria. The respondents' attitude towards physiotherapy was slightly low (53.5%), while their opinions and experiences of physiotherapy indicated some important issues. For example, 50% of them believed that physiotherapists did not create a good awareness about physiotherapy services and 55.5% admitted that they did not have enough information about physiotherapy services. The most potential factor reported by physicians that may affect the extent of utilization of physiotherapy services was the lack of physiotherapist's skills and knowledge to assess and treat patients (55.3%), followed by the limited knowledge of physicians regarding the types of physiotherapy services (44.5%) and the lack of cooperation between physicians and physiotherapists (40.7%). [Conclusion] There were some factors that limited the extent of utilization of physiotherapy services in SA. Physiotherapy academics and clinicians should attempt to change physicians' negative attitudes, promoting awareness to provide them with a better understanding of physiotherapy services.
