ABSTRACT
BACKGROUND: Peri-implantitis is an infectious disease that causes inflammation of the tissue surrounding an implant. The aim of this systematic review of the literature is to assess the effect of the use of lasers in the nonsurgical treatment of peri-implantitis in order to estimate its benefits compared to conventional therapies. MATERIALS AND METHODS: the review's protocol has been registered on PROSPERO international prospective register. The research strategy was performed according to the PRISMA guidelines. The inclusion criteria were: in vivo studies, written in English, measurements of clinical parameters, minimum follow-up at 6 months and with nonsurgical control group, studies about photodynamic therapy, randomized clinical trial, and clinical trial. Electronic (on Pubmed, Cochrane, LILACS and EPC databases) and manual searches (in articles' referencies) were conducted until July 2021. Risk of bias was assessed for each reference thanks to the Cochrane Collaboration's tool. RESULTS: A total of 12 randomized clinical trials, with a high level of evidence, were selected and investigated in this systematic review. A table summarizes data extracted from these articles. It appears that the parameters improve favorably by using lasers, but without any significant difference. CONCLUSION: in accordance with the analysis of studies, our results show that laser therapy with specific characteristics allows to obtain beneficial therapeutic effects on wound healing in the short and the medium-term concerning the clinical parameters in the nonsurgical treatment of peri-implantitis. Concerning its long-term usefulness, it has yet to be confirmed. However, its benefits remains limited since the results agree that the effects of the laser are similar to those obtained by using conventional therapy.
ABSTRACT
BACKGROUND: The World Health Organization (WHO) recommends that access to rehabilitation is a human right. To date, however, rehabilitation in South Africa has not been a health priority. The focus has rather been on saving lives from communicable diseases such as HIV/AIDs and TB, which has been increasingly successful. Whilst more South Africans are now living with pharmacologically managed chronic, communicable diseases, they often suffer significant challenges to their physical and mental health. Moreover, there are many health conditions in South Africa that have not attracted as much attention, and which also compromise individuals' capacity to contribute effectively to their own wellbeing, that of their families and communities, and to the general economy. These include birth trauma, degenerative neurological conditions, acquired injuries such as spinal cord damage, limb amputation or head trauma, and chronic noncommunicable diseases (heart or kidney disease, stroke). In the absence of robust prevalence studies, it is estimated that one-in-three adults suffer from at least one chronic health challenge. For South Africa not to invest in rehabilitation is counter-productive, as it means that a significant percentage of its population cannot contribute to its economy. In the face of scant health resources to underpin equitable rehabilitation services, evidence needs to be provided to demonstrate that for increased expenditure on rehabilitation, there will be increased return at individual, family, society, and country levels. PURPOSE: This article presents challenges and solutions to ensure that South Africa can meet WHO 2030 Rehabilitation Goals for equitable provision of effective public rehabilitation services using the WHO's health system building block framework.IMPLICATIONS FOR REHABILITATIONTo meet the challenge of providing rehabilitation for those in need requires country-specific, strategic, evidence-informed, and planned decisions in terms of best investment for highest return.Whilst there is sound international evidence for best-practice rehabilitation care, country-specific strategies are required to identify and address local barriers to evidence implementation.In South Africa, where rehabilitation has not been a priority to date, it is important that a planned and well-costed approach is taken to ensure provision of equitable, accessible, affordable, and evidence-based rehabilitation.Measuring social, economic, and educational return on investment from rehabilitation should be part of the South African service-delivery planning process.National data could be obtained through adding additional questions on disability to the national census and through local surveys and reports at various public health care facilities.

INTRODUCTION: Anterior knee pain (AKP) is a common condition frequently causing young, athletic patients to attend sports rehabilitation centres. Abnormal biomechanics are thought to contribute towards the development and chronicity of the condition. Gait analysis is commonly used to identify abnormal biomechanics in subjects with AKP, however the reliability of these measurements are unknown. Therefore, the aim of this study was to quantify the test retest reliability of hip, knee and ankle kinematics during gait in an AKP population so the true effects of an intervention can be established. METHODS: Thirty-one subjects with AKP attended the 3D Motion Analysis Laboratory at Tygerberg Medical Campus of Stellenbosch University in Cape Town, South Africa, for gait analysis. Participants returned seven days later at approximately the same time to repeat the gait analysis assessment from day one. The same assessor tested all subjects on both occasions. The intra-class correlation coefficients (ICC) and standard error of measurement (SEM) were calculated for hip, knee and ankle kinematic outcomes on the affected side and used for analysis. RESULTS: All outcomes obtained were acceptable to excellent test retest reliability scores for both measures of relative reliability (ICC = 0.78-0.9) and measures of absolute reliability (SEM = 0.94-4.2°). Hip frontal plane and ankle sagittal plane outcomes were the most reliable and had the lowest measurement error. Hip transverse plane outcomes were least reliable and demonstrated the highest measurement error. CONCLUSION: Hip, knee and ankle kinematic factors that are commonly associated with AKP can be measured reliably using gait analysis. Daily and weekly variation in symptoms in an AKP population may influence the reliability of knee sagittal plane outcomes. Therefore, it is important to document factors that could influence the kinematics such as pain, activity levels and the use of pain medication.
