Perceptions of family-centred care among caregivers of children with cerebral palsy in South India: An exploratory study.

BACKGROUND: Parental views and expectations about family-centred care (FCC) need to be understood for its successful implementation. Knowledge of caregiver's perceptions and needs, within their social and cultural context, forms the basis for effective health care partnerships with families. The purpose of this study was to explore perceptions about FCC among caregivers of children with cerebral palsy (CP) in South India. METHOD: Fourteen caregivers of children with CP (aged 4-12 years) living in rural areas of the coastal region of Karnataka, India, participated in this qualitative study. Face-to-face semi-structured interviews were recorded and transcribed for analysis using the framework and hybrid approaches. Thematic mapping of the categories and themes was done to explore relationships about perceptions of FCC. RESULTS: Caregiver's life emerged inductively as a new theme highlighting caregiver's own physical and mental health, family roles and well-being, integrating the onus of care with household responsibilities, limited participation in personal activities and social isolation. The qualitative findings revealed the ubiquity of respectful and trusting relationships with health professionals while expressing paucity of coordinated comprehensive care, sporadic partnerships and opportunities for shared decision-making; desire for receiving specific information related to child's progress and prognosis; and general information on community resources and the need of empowerment and support groups. CONCLUSION: Our study has practical implications for the implementation of FCC within the South Indian context, by recognizing unique caregiver needs and expectations in sync with cultural perspectives towards childhood disability such as societal stigma, values and traditional beliefs; attitudes towards medical professionals; and life stressors and gender responsibilities.

Community based study to assess the prevalence of diabetic foot syndrome and associated risk factors among people with diabetes mellitus.

BACKGROUND: Diabetic foot is one of the most significant and devastating complication of diabetes. The objective of this study was to assess the prevalence of diabetic foot syndrome (DFS) and the associated risk factors among people with diabetes mellitus. METHODS: A community based cross-sectional study was carried out among 620 subjects with diabetes mellitus (DM) in rural areas of Udupi district. The Michigan Neuropathy Screening Instrument was used to identify peripheral neuropathy. Ankle brachial index was used to identify peripheral arterial disease (PAD). Subjects with diabetic foot syndrome were classified according to the International Working Group on Diabetic Foot (IWGDF) classification system. RESULTS: The overall prevalence of DFS was 51.8%. Among them 31.3, 11.9 and 8.5% belonged to category 1, 2 and 3 respectively. Multivariate logistic regression analysis showed advancing age, low socio-economic status, sedentary physical activity and longer duration of DM were significant independent correlates of DFS. CONCLUSION: The overall prevalence of DFS was high among the study population; hence the screening for foot complications should start at the time of diagnosis of diabetes integrated with sustainable patient education at primary care level by training of health care providers at primary care level.

Application of low frequency and medium frequency currents in the management of acute and chronic pain-a narrative review.

Trancutaneous electrical nerve stimulation (TENS) and interferential therapy (IFT) have been a regular line of treatment for various types of acute and chronic pain. This review aims to compile the latest literature in pain management using these modalities which use low-frequency and medium-frequency currents. The Cochrane Library, Scopus, PubMed, MEDLINE, and CINAHL were searched and studies were examined from their inception till October 2013. After title and abstract screening the relevant studies were included for this review. We found through this review that even though TENS and IFT are used in management of pain, there is limited amount of high quality research available in this area. Most of the studies lack methodological quality and have a low sample size.

Ultrasound Evaluations of Ankle and Foot Muscles in Diabetic Peripheral Neuropathy Systematic Review with Meta-Analysis.

BACKGROUND: Diabetic peripheral neuropathy (DPN) is the prevalent microvascular complication of diabetes mellitus (DM). 30-50% of diabetics are likely to be affected by DPN. It significantly impacts the skeletal muscles, resulting in an accelerated loss of muscle mass. The objective of this systematic review was to evaluate the ankle and foot muscle changes in diabetic peripheral neuropathy using ultrasound. METHOD: A comprehensive search was conducted in Scopus, Embase, and PubMed databases, which yielded 64 studies, out of which 5 studies are included in this meta-analysis. RESULT: The meta-analysis shows that the thickness and cross-section area of the extensor digitorum brevis muscle are reduced in DPN as compared to the control group with p-value<0.004 and p-value<0.001, respectively. The thickness of MIL muscle was also smaller in DPN p-value=0.02. Similarly, the thickness and CSA of AH muscle are also reduced in DPN patients compared to the control group, with p-values of 0.21 and 0.14. CONCLUSION: Meta-analysis reveals that diabetic peripheral neuropathy (DPN) patients have reduced foot muscle thickness and cross-sectional area (CSA) compared to controls without neuropathy. This highlights the importance of ultrasound in detecting muscle atrophy early in diabetic patients since it provides objective measures beyond traditional screening with its real-time and non-invasive nature.

Effect of a Customized Physical Activity Promotion Program on Visceral Fat and Glycemic Parameters in Individuals With Prediabetes: A Randomized Controlled Trial.

BACKGROUND: Physical activity of any amount results in substantial health benefits. However, public awareness of physical activity benefits in chronic diseases is inadequate in India. Prediabetes is a significant health issue on a global scale. Visceral fat (VF) is considered as an early predictor of prediabetes. Ethnicity and race have a substantial impact on VF. Hence, this study intended to evaluate the effect of a customized physical activity promotion program on VF and glycemic parameters in individuals with prediabetes. METHODS: In the current, parallel group randomized controlled trial, a total of 158 participants were recruited: 79 in intervention and 79 in control group. The study included the prediabetes individuals based on American Diabetes Association criteria. Participants from the intervention group received the customized physical activity promotion program for 24 weeks. The primary outcome measures of the study were VF level and glycemic parameters that included fasting blood sugar and glycosylated hemoglobin. Two-way mixed analysis of variance was used to study the mean difference of an outcome between 2 groups over time. RESULTS: The study found a statistically significant interaction between the intervention and times on VF level, F1,136 = 23.564, fasting blood sugar levels, F1,136 = 8.762, and glycosylated hemoglobin levels, F1,136 = 64.582 at the end of 24 weeks (P < .05). CONCLUSIONS: This study concluded that a customized physical activity promotion program was effective in reducing VF in individuals with prediabetes as compared with controls. It improved glycemic control by reducing fasting blood sugar and glycosylated hemoglobin levels.

Efficacy of comprehensive structured exercise program on claudication pain and quality of life in type 2 diabetes mellitus with peripheral arterial disease.

Background: Peripheral arterial disease is one of the leading complications of type 2 diabetes mellitus. The primary symptom of peripheral arterial disease is claudication pain. Exercise is known to improve the claudication pain, thereby improving the quality of life. Methods: A total of 74 participants were recruited in each group and a detailed demographic assessment was done for all the participants. The study group received a comprehensive structured exercise program and standard care whereas the control group received only the standard care. Progression of the exercise was made at the 6th week of the protocol. All the outcome measures were reassessed after the 12th weeks for both study and control group. Results: The mean age of participants was 60.78 ± 11.29 (years) and 59.98 ± 11.42 (years) for the study and control group, respectively. There was a statistically significant difference in toe brachial index (p < 0.001), ankle brachial index (p < 0.001), 6-minute walk distance (p < 0.001), WHO-BREF quality of life questionnaire (p < 0.001), and walking ability ((p < 0.001) in the study group in comparison to the control group. Conclusion: In the present study we found that comprehensive structured exercise program improves the arterial indices, quality of life, walking ability and reduces claudication pain in type 2 diabetes mellitus with peripheral arterial disease. Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-024-01426-2.

CONCLUSIONS: The study reveals that a 12-week structured exercise training program effectively reduces insulin resistance, improves quality of life, enhances functional capacity, and improves glycaemic control in type 2 diabetes mellitus.

Effect of Novel Laser Shoe Photobiomodulation on Neuropathic Pain and Plantar Pressure Profile in Type 2 Diabetes Mellitus with Peripheral Neuropathy.

BACKGROUND: Photobiomodulation (PBM) or Low-level laser is used to treat diabetic foot complications. The existing method of laser application to the foot did not cover the foot's entire area to improve the foot's microcirculation. Therefore, we have developed a cost-effective Special LASER Shoe device, focusing exclusively on the entire foot region to manage neuropathic pain and other symptoms in individuals with type 2 diabetes mellitus. OBJECTIVE: The main objective of the present study was to evaluate the effect of this newly developed special laser shoe PBM on neuropathic pain and plantar pressure profile in individuals with type 2 diabetes mellitus with neuropathy. METHODS: We included 60 participants with diabetic peripheral neuropathy of both genders and age more than 20 years. Participants were treated with PBM by a specially designed novel Laser Shoe. Outcomes were clinical variables like Vibration Perception Threshold (VPT), Visual Analogue Scale (VAS), Michigan neuropathy screening instrument A&B, Ankle-Brachial Index (ABI), and Static dynamic gait parameters. RESULTS: Participants were with an average age of 62, and the average duration of diabetes was 11 years. Analysis showed a significant difference in VPT, VAS, Michigan neuropathic screening inventory, and ankle-brachial index. (P < 0.05). CONCLUSION: We conclude that Novel laser shoe photobiomodulation using 'Laser Shoe' effectively reduces peripheral neuropathic pain. It is also effective in reducing average and maximum plantar pressure. Reduction in neuropathic pain and improvement in plantar pressure distribution can reduce further complications.

Effect of Core Exercises on Clinical and Functional Outcomes After Total Knee Arthroplasty in Individuals With Knee Osteoarthritis: A Systematic Review.

BACKGROUND: Core muscles constitute the centre of the kinetic chain, and core exercises have been effective in improving outcomes in many postsurgical lower extremity musculoskeletal conditions. However, the literature on the implementation of core exercises after TKA has not been summarised. OBJECTIVE: The objective was to review the evidence on the effect of core exercises on clinical and functional outcomes after TKA in individuals with knee osteoarthritis (OA). METHODS: PubMed, Scopus, CINAHL, Web of Science, the Cochrane Library, and ProQuest databases were explored with appropriate keywords for studies published on the effect of core exercises on TKA from inception to 1 April 2024. Two authors independently screened the titles and abstracts and full-texts, and a third author solved the discrepancies. Risk of bias assessment was done with the Joanna Briggs Critical Appraisal tool. The final articles were systematically summarised. RESULTS: A total of 1485 records were retrieved. Sixty-four articles were included for screening full-texts, and four articles were ultimately included. Core exercises were administered for three to 6 weeks. The administration of core exercises along with the standard knee rehabilitation programme significantly improved balance, mobility, knee function, transverse abdominis muscle thickness, transversus abdominis contraction, and quality of life after TKA (p < 0.05). CONCLUSIONS: Core exercises can be administered as an adjunct to standard rehabilitation programs to improve clinical and functional outcomes after TKA. However, there is a dearth of literature in this domain, and more studies are warranted. TRIAL REGISTRATION: PROSPERO Registration Number: CRD42024542992.

Patient education for individuals with Interstitial Lung Disease: A scoping review.

Objectives: Interstitial Lung Disease (ILD) is a severe and rapidly progressing disease with a high fatality rate. Patient education (PE) has been demonstrated to promote long-term adherence to exercise and lifestyle improvements by assisting patients in developing self-management techniques. Our scoping review's goal was to chart out the prevailing level of research about the content, processes, and effectiveness of PE for patients with ILD. Methods: The relevant databases were searched using the rules provided by Arksey and O'Malley in 2005 and the Joanna Briggs Institute reviewers' manual 2015: an approach for JBI scoping reviews. Individuals with ILD, published in English between the years of inception and 2020, and describing PE administered by various healthcare practitioners were among the 355 studies found and reviewed. Thirteen studies met these criteria. Results: PE delivery process, delivery techniques, quality of life assessments, common PE themes, and healthcare professional participation were all recognized and cataloged. Conclusion: Despite the fact that healthcare professionals (physicians, nurses, and physiotherapists) provide PE to patients with ILD regularly, the PE provided varies greatly (contents of PE, process of delivery and delivery techniques). During the scoping review, a significant variation in the themes was addressed. They could not provide any evidence-based specific recommendations for all healthcare practitioners due to the studies' heterogeneity and lack of effectiveness measures.

Exploring extended reality for diabetes education & self-management - A bibliometric analysis from 1999 to 2023.

BACKGROUND: Diabetes Mellitus (DM) has emerged as a rapidly growing non-communicable disease (NCD) across developed & developing countries. People with diabetes mellitus experience health implications. They develop associated microvascular complications such as neuropathy, nephropathy & retinopathy and macro-vascular complications like coronary artery disease, stroke, amputations etc. These complications increase the socio-economic burden of people living with diabetes. Self-management of diabetes through education is a strong tool that remains under-utilized in clinical settings. The objective of the present study was to explore the role of extended reality for diabetes education & self-management. METHODOLOGY: The present study is a bibliometric analysis performed on the Scopus database with keywords: diabetes education, self-management, extended reality, virtual reality, augmented reality, mixed reality, and Boolean operators AND, OR. The search period ranged from inception till 4th July 2023 with restriction to English language articles. A total of 89 documents were identified in Scopus under multiple domains such as Engineering, Medicine, Health Professions, Nursing among others. The data was exported to the VOS Viewer software for network analysis. RESULTS: Out of the total 89 documents, 45-original research, 26-review, 12-conference paper, 3-book, 2-book chapters & 1-note. The highest publications were from the Medicine category. The year of publication of the included documents ranged from 1999 till 2022. The network analysis was performed to explore the association between the included studies (co-authorship, co-occurrence, citation analysis, bibliographic coupling). CONCLUSION: The network analysis found the USA to be the leading publisher and the National Institute of Health (NIH) to be the leading funding source. There is limited evidence and a strong future scope to strengthen research productivity on extended reality for diabetes education & self-management.

Effect of exercise-based rehabilitation on functional capacity and renal function in type 2 diabetes mellitus with nephropathy: a randomized controlled trial.

INTRODUCTION: Diabetic nephropathy is a growing public health challenge with implications on health. Renal function decline impacts the functional ability and overall health and well-being of individuals with diabetic nephropathy due to development of several renal manifestations. The objective of the study was to determine the effect of an exercise-based rehabilitation program on functional capacity and renal function among individuals with type 2 diabetic nephropathy. METHODS: A total of 283 individuals were screened and 60 eligible participants aged 45-70 years with diabetic nephropathy were randomly allocated (n = 30 each) to the intervention group (IG) and control group (CG), respectively. The study outcome measures comprised of functional capacity (6-min walk test) and renal function assessed at baseline, 12th week and 24th week. Participants allocated to IG received 12 weeks of exercise based rehabilitation (comprising of supervised + home-based exercises) along with standard care and followed-up till 24th week. RESULTS: The repeated measures ANOVA with Greenhouse-Geisser correction indicated significant timepoint*group interaction effect for 6-min walk distance F (1.71, 90.59) = 619, p < 0.001, serum creatinine F (1.23, 65.14) = 174.8, p < 0.001, estimated glomerular filtration rate F (1.15, 60.88) = 105.2, p < 0.001, serum urea F (1.48, 78.45) = 261.4, p < 0.001 and urine protein F (1.13, 59.82) = 4.58, p < 0.328. CONCLUSION: The study found that exercise based rehabilitation improved both functional capacity and renal function among individuals with type 2 diabetic nephropathy.

Effect of exercise training on functional capacity & quality of life in head & neck cancer patients receiving chemoradiotherapy.

BACKGROUND & OBJECTIVES: Patients with head and neck cancer (HNC) undergoing chemoradiotherapy (CRT) suffer from fatigue causing a decrease in functional capacity and quality of life (QoL). Limited research in the field of exercise training among these patients demanded the need for this study to assess the effects of exercise training on functional capacity and quality of life. METHODS: A randomized controlled trial was conducted on 48 patients with HNC undergoing CRT. The exercise group received an individually tailored, supervised, exercise programme for six weeks, while the control group did not receive any form of exercise. Functional capacity and QoL were assessed at baseline and at the end of the intervention using the six minute walk distance (6MWD) and medical outcomes survey short form 36 (SF 36). RESULTS: The mean age of patients was 52 yr with 42 males. After six weeks, the 6MWD improved by 42 metres (P<0.05) in the exercise group while the control group showed a decrease by 96 metres (P<0.001). There was an improvement on the mental component score (MCS) of SF36 for the exercise group (4.8; P<0.05) and the physical component score (PCS) remained almost the same, while a decrease in PCS and MCS was seen in the control group (-5.9; P=0.064 and -17.3; P<0.05). When 6MWD and SF36 were compared between the groups, there was a statistically significant difference (P<0.001) seen after six weeks. INTERPRETATION & CONCLUSIONS: Our results showed that the functional capacity and QoL decreased among those not receiving a supervised exercise program, while exercise training improved functional capacity and QoL in HNC patients undergoing CRT.

Effect of Multifactorial Balance Rehabilitation Program on Risk of Falls and Functional Fitness in Older Adults with Diabetic Peripheral Neuropathy.

BACKGROUND: Increasing age and the added disadvantage of diabetic peripheral neuropathy (DPN) put the individual at a higher risk of falls and reduced functional fitness. However, there is a dearth of literature on multifactorial balance intervention, especially targeting the needs of older adults with DPN. OBJECTIVE: The current study aimed to determine the effect of a multifactorial balance rehabilitation program on fall risk and functional fitness in older adults with DPN. METHODS: In this pre-post experimental study, 30 independently ambulating older adults (71.2 ± 4.70 years) with DPN, who were at risk of falling (timed up and go score ≥ 9.4 seconds), were recruited. Along with the standard care, all the participants received 12 weeks of the multifactorial balance rehabilitation program. RESULTS: Fall risk using the Fullerton Advanced Balance scale and functional fitness using the Senior Fitness Test were measured at baseline and after 12 weeks of the intervention. The intervention reduced the risk of falling score significantly (MD = 6.17, p < .001). All six parameters of functional fitness improved after 12 weeks of intervention. The improvement in lower limb strength (MD = 1.53 times), upper limb strength (MD = 2.48 times), endurance (MD = 16.07 seconds), lower limb flexibility (MD = 2.02 inches), upper limb flexibility (MD = 1.47 inches), and dynamic balance (MD = 1.53 seconds) was statistically significant at p < 0.05. CONCLUSION: This study provided encouraging evidence about the potential of multifactorial balance rehabilitation to reduce the risk of falling and improve functional fitness in older adults with DPN.

Measurement properties of physical activity in adults with bronchiectasis: A systematic review protocol.

People with bronchiectasis reduce their physical activity (PA) due to muscle weakness, dyspnea, fatigue, reduced exercise capacity and frequent cough with expectoration. Patient-reported and objective physical assessment methods have been used to evaluate PA in people with bronchiectasis. In the literature, significant differences in the PA measured using patient-reported outcome measures when compared with the objective methods. Given the availability of many PA assessment tools, it is tedious for the clinician or researcher to choose an outcome measure for clinical practice or research. The evidence on validity and reliability in bronchiectasis are unclear. Objectives: To identify the PA assessment tools, describe and evaluate the literature on psychometric properties of instruments measuring and analyzing PA. Methods: The search will be conducted in PubMed/Medline, Cochrane Central Register of Controlled Studies, Scopus and EMBASE databases. The keywords, index terms and synonyms of the following words will be used: bronchiectasis, physical activity, and outcome measures. Published studies of adult with clinical and/ or radiologically diagnosed bronchiectasis, aged >18 years, any gender and studies that assessed PA and/or if there are reports on measurement properties of PA will be included in the review. Studies using qualitative research methods, narrative reviews, letters to editors and editorials will be excluded. The quality of the study will be assessed and data will be extracted. Any disagreement will be resolved in the presence of an author not involved in the screening or selecting studies. Discussion: By assessing the quality of studies on measurement properties, this review will help researchers choose the outcome measure to evaluate the effects of interventions on PA. This review will identify the suite of outcome measures of PA for people with bronchiectasis that can be used for research and clinical purpose.

Effect of transcranial photobiomodulation on electrophysiological activity of brain in healthy individuals: A scoping review.

BACKGROUND OBJECTIVE: Transcranial photobiomodulation (tPBM) is a safe and non-invasive treatment that has recently emerged as an effective technique to apply near-infrared or red light to activate neural tissues. The objective is to review the literature on the effect of tPBM on electrophysiological activity in healthy individuals. METHODS: Literature was searched through PubMed, Scopus, Web of Science, Cumulated Index to Nursing and Allied Health Literature (CINAHL), Embase, and Ovid for transcranial photobiomodulation therapy in healthy individuals age group 18-80 years of either gender having electroencephalography as an outcome. Critical appraisal of included Randomized Controlled Trials and non-randomized experimental studies was done using Joanna Briggs Institute (JBI) critical appraisal tool. RESULTS: A database search yielded a total of 4156 results. After eliminating 2626 duplicates, 1530 records were left. 32 articles were considered for full-text screening after 1498 records were excluded through title and abstract screening. 10 articles were included in this review. tPBM has been found to increase the higher electrophysiological oscillations and there is inconclusive evidence targeting the lower oscillatory electrophysiological frequencies. CONCLUSION: Transcranial photobiomodulation can have promising effects on the electrophysiological activity of the brain in healthy individuals.

Effect of Covid-19 lockdown/ compulsory work from home (WFH) situation on musculoskeletal disorders in India.

OBJECTIVE: To estimate self-reported musculoskeletal disorders among Indian population in work from home COVID-19 lockdown and its association on various socio-demographic and occupational factors among them. METHODS: The present cross-sectional study was conducted on working Indian professionals, through an online self-reported survey during the COVID-19 work from the home situation. Details about the perceived musculoskeletal discomforts, weight gain or loss, physical activity profile, number of working hours, total sedentary time, and satisfaction perceived with working from home were recorded from the participant responses and thereafter analyzed. RESULTS: A total of 281 responses were analyzed. 47.6% of respondents reported musculoskeletal disorders before lockdown, whereas 53.6% reported them during the lockdown period. 10% of respondents reported declination in physical activity. Finding of the chi-square for association and Spearman's rho correlation analysis suggested that gender, pre-existing musculoskeletal discomforts, current sedentary time, and long working hours are significantly associated with musculoskeletal discomforts during work from home COVID-19 lockdown. CONCLUSION: This study concluded the increment in the self-reported musculoskeletal disorders among working Indian professionals during work from home COVID-19 lockdown. The study also found the significant association between MSD and gender, working hours, sedentary time and pre-existing musculoskeletal discomforts.

Analysis of time-domain indices, frequency domain measures of heart rate variability derived from ECG waveform and pulse-wave-related HRV among overweight individuals: an observational study.

Background: Research on the compatibility of time domain indices, frequency domain measurements of heart rate variability obtained from electrocardiogram (ECG) waveforms, and pulse wave signal (pulse rate variability; PRV) features is ongoing. The promising marker of cardiac autonomic function is heart rate variability. Recent research has looked at various other physiological markers, leading to the emergence of pulse rate variability. The pulse wave signal can be studied for variations to understand better changes in arterial stiffness and compliance, which are key indicators of cardiovascular health. Methods: 35 healthy overweight people were included. The Lead II electrocardiogram (ECG) signal was transmitted through an analog-to-digital converter (PowerLab 8/35 software, AD Instruments Pty. Ltd., New South Wales, Australia). This signal was utilized to compute Heart Rate Variability (HRV) and was sampled at a rate of 1024 Hz. The same AD equipment was also used to capture a pulse signal simultaneously. The right index finger was used as the recording site for the pulse signal using photoplethysmography (PPG) technology. Results: The participants' demographic data show that the mean age was 23.14 + 5.27 years, the mean weight was 73.68 +  7.40 kg, the mean body fat percentage was 32.23   +  5.30, and the mean visceral fat percentage was 4.60   +  2.0. The findings revealed no noticeable difference between the median values of heart rate variability (HRV) and PRV. Additionally, a strong correlation was observed between HRV and PRV. However, poor agreement was observed in the measurement of PRV and HRV. Conclusion: All indices of HRV showed a greater correlation with PRV. However, the level of agreement between HRV and PRV measurement was poor. Hence, HRV cannot be replaced with PRV and vice-versa.

Dose-Response Relationship of Photobiomodulation Therapy on Matrix Metalloproteinase in Healing Dynamics of Diabetic Neuropathic Ulcers-An in vivo Study.

Individuals with diabetic foot ulcers have overlapped the inflammatory, proliferative and remodeling phase, making the tissue vulnerable to delayed healing responses. We aimed to establish the dose-response relationship of photobiomodulation therapy of different doses and matrix metalloproteinases in the healing dynamics of diabetic neuropathic ulcers. Diabetes was induced in 126 Albino Wistar rats, and neuropathy was induced to the hind paw by a sciatic nerve injury method. An excisional wound was created on the neuropathy-induced leg. Photobiomodulation therapy of dosages 4, 6, 8, 10, 12 and 15 J cm-2 and wavelength 655 nm and 808 nm was irradiated. Photobiomodulation therapy of dosages 4, 6 and 8 J cm-2 showed better wound healing properties with optimized levels of matrix metalloproteinases-1 and 8. We observed a strong dose response in the experimental group treated with 6 and 8 J cm-2 . The findings from the present study conclude that photobiomodulation therapy of dosages 4, 6 and 8 J cm-2 is suggestive of usefulness in diabetic neuropathic ulcer healing. Markers like matrix metalloproteinases may give a clear direction on response to the therapy. Based on the findings from the present study, we recommend to validate the findings for safety and efficacy in future through human prospective randomized controlled clinical trials.
