    ENGLISH SUMMARY : Background: Sub-Saharan Africa has the greatest disease burden due to HIV globally. Improved access to better antiretroviral regimens has increased numbers and longevity of people living with HIV (PLWH). However, recent research has indicated a seemingly increased propensity for both falls and accelerated bone loss at younger-than-expected ages in PLWH. The benefits of anti-retroviral drugs may be overshadowed if PLWH suffer from excess morbidity such as falls, fractures and functional impairments. Physiotherapists play a crucial role in optimising function and quality of life of PLWH through prevention of falls and reducing the harm that results. Aim: This research aimed to describe the extent and nature of existing research relating to falls in PLWH and describe the relationship between bone demineralisation and falls in PLWH. It further aimed to explore physiotherapists’ awareness of falls risk and accelerated bone demineralisation in PLWH and their perceptions about current falls prevention in the care of PLWH in selected regions of sub-Saharan Africa. Method: The research consisted of a scoping review and a primary study. The scoping review included peer-reviewed studies (excluding narrative reviews) available in English with any information referring to falls in PLWH. Any data regarding bone demineralisation in these studies were also extracted. The results were used to explain concepts arising from the qualitative study. In the primary study, an interpretative exploratory qualitative research method with a phenomenological approach was employed to explore physiotherapists’ perceptions and experiences regarding bone health and falls in PLWH. In-depth semi-structured telephonic interviews were used to collect data from 21 physiotherapists working in primary HIV care. Transcribed interview data were coded in Atlas.ti.8® and analysed using inductive thematic analysis. Results: The scoping review identified 14 studies on falls in PLWH, with all but one study published in high income countries (HIC). Prevalence of falls in PLWH approximated that of seronegative counterparts, but the studies were mostly in middle-aged to older adults in whom geriatric syndromes may already be prevalent. Considerable agreement existed for risk factors regarding use of medications while evidence regarding functional and cognitive impairments were variable. Few studies compared risk factors for falls in PLWH with those in age and sex-matched seronegative population. There is currently no evidence for interventions to prevent or reduce falls risk in PLWH. The primary study revealed a lack of awareness by physiotherapists of falls risk and bone demineralisation in PLWH. As such, physiotherapists did not link falls or fractures to HIV or antiretroviral therapy (ART) when they did observe such events during their general patient assessments. However, in retrospect, some physiotherapists were able to recognise risk factors linked to falls in those with HIV. Current services for falls prevention as perceived by the physiotherapists were sub-optimal and lacked a patient-centred approach. Conclusion: Physiotherapists may need to be more aware of the potential risk of falls and bone demineralisation in PLWH and routinely assess for these phenomena in both older and younger PLWH. More awareness also needs to be created among other healthcare professionals and PLWH. Meanwhile, research on falls in younger PLWH and in sub-Saharan Africa, where HIV is most prevalent and where more robust clades exist, is needed. Relevant stakeholders including governments and PLWH themselves require concerted efforts in addressing health system challenges affecting the implementation of falls prevention services to PLWH at primary care level.
