A scoping review on the body awareness rehabilitation after stroke: are we aware of what we are unaware?
Front Neurol
January 2025
IRCCS Centro Neurolesi Bonino-Pulejo, Messina, Italy.
Body awareness (BA) is a complex multi-dimensional construct that refers to the subject's ability to consciously perceive and integrate sensory and proprioceptive information related to the position, movement, and balance of one's own body and body parts. Since it involves multiple brain regions and include different functional networks, it is very often affected by cerebrovascular damage such as stroke. Deficits in the ability to monitor our actions and predict their consequences or recognize our body parts and distinguish them from those of others may emerge after stroke.

Introduction: Motor-imagery-based Brain-Machine Interface (MI-BMI) has been established as an effective treatment for post-stroke hemiplegia. However, the need for long-term intervention can represent a significant burden on patients. Here, we demonstrate that motor imagery (MI) instructions for BMI training, when supplemented with somatosensory stimulation in addition to conventional verbal instructions, can help enhance MI capabilities of healthy participants.

Previous studies suggested that pitch characteristics of lexical tones in Standard Chinese influence various sensory perceptions, but whether they iconically bias emotional experience remained unclear. We analyzed the arousal and valence ratings of bi-syllabic words in two corpora (Study 1) and conducted an affect rating experiment using a carefully designed corpus of bi-syllabic words (Study 2). Two-alternative forced-choice tasks further tested the robustness of lexical tones' affective iconicity in an auditory nonce word context (Study 3).

Epidermal melanocytes form synaptic-like contacts with cutaneous nerve fibers, but the functional outcome of these connections remains elusive. In this pilot study we used our fully humanized re-innervated skin organ culture model to investigate melanocyte-nerve fiber interactions in UV-B-induced melanogenesis. UV-B-irradiation significantly enhanced melanin content and tyrosinase activity in re-innervated skin compared to non-innervated controls, indicating that neuronal presence is essential for exacerbating pigmentation upon UV-B irradiation in long-term culture.

Physical Medicine and Rehabilitation, Centro de Reabilitação do Norte, Vila Nova de Gaia, PRT.
Background: Painful hemiplegic shoulder (PHS) is a prevalent and challenging complication following a stroke and can significantly impair a patient's engagement in rehabilitation, leading to poorer functional outcomes and extended hospital stays. This retrospective cohort study aims to investigate the incidence, etiology, and management of PHS in stroke inpatients, focusing on the effectiveness of various therapeutic interventions.
Methods: We conducted a retrospective analysis of subacute stroke inpatients who developed PHS during rehabilitation at a single center.
