Strengthening research capacity in Africa is vital for tackling pressing health, educational and socioeconomic challenges facing the continent. At the core of this effort is the cultivation of innovative research leaders through postgraduate training programmes that incorporate mentorship-infused supervision. Such models have demonstrated potential in improving research skills, boosting academic productivity and fostering leadership development among emerging scholars. This systematic review and meta-synthesis protocol aims to examine existing mentorship-infused supervision practices across African higher education institutions. The review seeks to identify effective models, uncover common challenges and barriers, and generate evidence-based recommendations to develop sustainable, contextually relevant strategies. Insights from this work will inform policies and practices to enhance postgraduate research training, advance research leadership and contribute to the broader goal of strengthening research ecosystems across Africa.
A systematic review and thematic meta-synthesis will be undertaken, focusing on qualitative research studies as well as the qualitative components of mixed-methods studies. Relevant studies published in English will be identified through a comprehensive search strategy. The electronic databases, including Medline/PubMed, Scopus, Web of Science, African Journals Online, EMBASE and CINAHL, will be searched to capture a wide range of peer-reviewed articles and grey literature. Databases will be searched from March 2026. Two reviewers will independently perform study selection, data extraction, quality assessment and evaluation of risk of bias, using the Critical Appraisal Skills Programme checklist.
This systematic review and meta-synthesis will analyse publicly available literature and does not require ethical approval, as it involves no primary data collection. It will adhere to established ethical and methodological standards, including proper citation and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The findings will be widely disseminated through open-access journal publication, conference presentations and targeted reports for universities, research institutions and policymakers to inform and support mentorship-based postgraduate research supervision across Africa.

This study investigates cortical reorganisation and hemodynamic responses in individuals with lower extremity amputation and replantation using functional near-infrared spectroscopy (fNIRS). A total of 15 healthy controls, four left lower limb amputees and one replantation patient were included. Oxyhemoglobin (oxy-Hb) activations were measured during 10 unilateral lower limb motor tasks (toe, ankle, knee and hip movements). Non-parametric analyses revealed significant differences in cortical activation between amputees and controls, particularly during knee flexion and extension. Three-dimensional contrast maps demonstrated that oxy-Hb activity in amputees extended from the M1-leg area into somatosensory regions, reflecting neuroplastic remapping. In contrast, the replantation patient exhibited activation patterns closer to the control group, especially in knee and hip tasks. These findings indicate that fNIRS can sensitively capture hemispheric dynamics during unilateral lower limb movements and highlight neuroplastic adaptations following amputation and replantation. Such insights may guide future neuroprosthetic design and rehabilitation strategies.
