Eight studies provided a rationale for adapting the 6MWT. Space constraint was the most common reason for adaptation.

The most common reason (space constraints) for adapting the 6MWT in LRS was addressed through adaptations in course length and/or configuration. The results of this review suggest that the value of the ATS-guided 6MWT in LRS may need to be re-evaluated.

Using adapted forms of the 6MWT may lead to an underestimation of a patient's abilities, misinformed discharge and developing inappropriate exercise programmes. Additionally, diverting from ATS guidelines may affect the continuity of care.

Exercise forms an important component in the management of ankylosing spondylitis (AS). The objective of our study was to determine the effects of a 6-month swimming, land-based stretching, strengthening and breathing exercise intervention in AS patients.

A total of 29 (14 females, 15 males) patients diagnosed with AS according to the Modified New York Criteria participated in our study. Participants were randomly assigned to an exercise group (ASE) (16 participants) and a control group (ASC) (13 participants). Erythrocyte sedimentation rate and C-reactive protein (CRP); anthropometric measurements; pulmonary function; aerobic capacity; balance; Bath AS Metrology Index; Bath AS Disease Activity Index and the Bath AS Functional Index were assessed.

Erythrocyte sedimentation rate and CRP did not change notably within or between the groups from pre- to post-intervention. The between group analyses of the physical assessments favoured the ASE with observable improvements in chest expansion (

= 0.002), foristration not undertaken at the time of writing.

Runners in under-resourced communities in parts of South Africa present with a high prevalence of patellofemoral pain (PFP), which affects their level of participation in sporting activities. Therefore, a specific rehabilitation approach is necessary to manage the PFP-related needs of these runners within their means and reach.

To develop a community-based rehabilitation (CBR) implementation framework for PFP amongst runners in under-resourced communities.

Our study used the Delphi technique to develop an appropriate rehabilitation implementation framework for PFP in community-based settings. Sport medicine experts, involved in the treatment and rehabilitation of PFP, were recruited to participate. The Delphi process consisted of three rounds to attain consensus amongst the experts on the components and elements that could be contained in a rehabilitation implementation framework for the management of PFP. Experts rated the framework items using a five-point Likert scale.

A total of 19 experts participated in our study 10 were females and 9 were males of whom 13 were aged between 36 and 55 years. Most were local experts (15) with 11-20 years of clinical experience. Four core rehabilitation implementation items were identified through the Delphi process. These were (1) the establishment of transdisciplinary rehabilitation teams, (2) upskilling of available clinicians, their assistants and trainers, (3) implementation of a CBR programme at low-level or no-cost and (4) referral of cases to secondary or tertiary institutions for further management.

Consensus was reached for a comprehensive CBR implementation framework aimed at addressing the specific needs of runners with PFP in under-resourced communities.

A further study to test the feasibility of the agreed-upon intervention is recommended.

The announcement of a national lockdown in South Africa had country-wide impact on the delivery of health services. Strategies included prioritisation of patients and protecting patients who were considered at risk, resulting in the need for cancellation and temporary termination of many outpatient therapy services. This necessitated the urgent need to come up with a way of delivering physiotherapy rehabilitation services to patients in a more non-traditional format. Telerehabilitation allows for the provision of services by using electronic communication, thus ensuring that patients are still able to access necessary rehabilitation services.

This is a prospective, mixed method study with participants recruited from the outpatient physiotherapy department of Chris Hani Baragwanath Academic Hospital (CHBAH). AB680 Telerehabilitation services will be provided via the patients' preferred method of communication. On discharge, participants and therapists will be asked about their experiences of telerehabilitation.

Because of the current coronavirus disease 2019 (COVID-19) pandemic, patients are unable to receive traditional face-to-face physiotherapy services. Telerehabilitation offers a suitable alternative to treatment, but the feasibility, outcome and experiences of offering these services in the public health system have not been studied.

This study will determine whether telerehabilitation is a feasible service that can be offered in the COVID-19 pandemic, as well as post-pandemic, to enable physiotherapists to access those patients who are often unable to attend physiotherapy because of transport costs and various other reasons for non-attendance.

The results of this study may indicate a way of managing patients in situations where face to face therapy cannot be undertaken.

Pan African Clinical Trial Registry, PACTR202103637993156.The causative agent of the ongoing pandemic in the world is SARS-CoV-2. The research on SARS-CoV-2 has progressed with lightning speed on various fronts, including clinical research and treatment, virology, epidemiology, drug development, and vaccine research. Recent studies reported that sera from healthy individuals, who were confirmed negative for SARS-CoV-2 by RT-PCR method, tested positive for antibodies against spike and nucleocapsid proteins of SARS-CoV-2. Further, such antibodies also exhibited neutralizing activity against the virus. These observations have prompted us to prepare a commentary on this topic. While the preexisting antibodies are likely to protect against SARS-CoV-2 infection, they may also complicate serological testing results. Another unknown is the influence of preexisting antibodies on immune responses in individuals receiving vaccines against SARS-CoV-2. The commentary identifies the potential limitations with the serological tests based on spike and nucleocapsid proteins as these tests may overestimate the seroprevalence due to cross-reactive antibodies.
