“…[2,7] Evidence also suggests that impaired hand gesture imitation is linked to posterior lesions in the left inferior parietal lobule (LIPL) and temporal-parietal-occipital junction (TPOJ), while impaired finger gesture imitation is associated with lesions in the inferior frontal gyrus (IFG). [37,38] These brain regions are responsible for motor planning, coordination, and the integration of sensory-motor information.

Objective : This study aimed to develop and concurrently validate a simple, resource-efficient, and time-efficient bedside tool based on day-to-day movement tasks for evaluating upper limb function in stroke survivors. Methods: The study’s qualitative and cross-sectional component was conducted in 2 stages. At the initial stage, a relevant literature review was carried out to conceptualize and define the theoretical framework of day-to-day movement tasks, in evaluating upper limb function. Subsequently, an initial item pool of 18 upper limb and hand movements was developed. A Delphi method was employed to verify content validity of the initial 18-item scale using an expert consensus panel of 6 subject matter experts (three neurologists, two physiotherapists, and 1 occupation therapist). At the first round, 4 items were excluded using expert panel consensus method. During the second round of the content validation phase, the remaining 14-item scale was revised and refined to a final 12-item scale by the expert panel using a 5-point Likert rating scale. A score of 2 or below by at least two experts on a 5-point Likert scale was used as the criterion to modify or remove the components. During the second stage, the final 12-item bedside upper limb evaluation tool (BUFET) scale underwent concurrent validation using purposive sampling of 25 stroke survivors. Concurrent validity was assessed by correlating the BUFET score with Wolf Motor Function (WMT) scores using Spearman's correlation coefficient and internal consistency was evaluated through Cronbach’s alpha. Results: Concurrent validity and internal consistency of the scale were supported by a high correlation coefficient (r = 0.937; p<0.001) with WMFT and high Cronbach’s alpha (0.948). Conclusions: The newly developed BUFET was found to be a valid and reliable bedside tool in the evaluation of upper limb functions and can be administered in a resource and time-efficient manner.

Background Numerous tools are available for evaluation of upper limb (UL) functions among stroke survivors. Despite the excellent psychometric properties, many require considerable amount of time, are resource-intensive, and often impractical for bedside evaluation. Objectives To develop and concurrently validate a simple, resource-efficient, and time-efficient bedside tool for evaluating UL function in stroke survivors. Methods Relevant literature review was carried out to conceptualize and define the theoretical framework of day-to-day UL movement tasks. Subsequently, an item pool of 18 UL movements was developed. A mini-Delphi method was employed to verify content validity. During the iterative rounds, 18-items were revised and refined to a 12-items scale. The final bedside upper limb evaluation tool (BUFET) scale underwent concurrent validation by correlating the scores with Wolf Motor Function Test (WMFT) scores using Spearman’s correlation coefficient. Internal consistency was evaluated through Cronbach’s alpha. Results Concurrent validity and internal consistency of the scale were supported by a high correlation coefficient (r = 0.937; p<0.001) with WMFT and high Cronbach’s alpha (0.948). Conclusions Newly developed BUFET was found to be a valid and reliable bedside tool in the evaluation of upper limb functions and can be administered in a resource and time-efficient manner.

Ideomotor apraxia is a cognitive disorder most often resulting from acquired brain lesions (i.e., strokes or tumors). Neuroimaging and lesion studies have implicated several brain regions in praxis and apraxia, but most studies have described (sub)acute patients. This study aimed to extend previous research by analyzing data from 115 left hemisphere chronic stroke patients using the praxis subtest of the Western Aphasia Battery, which is divided into four action types: facial, upper limb, complex, and instrumental. Lesion–symptom mapping was used to identify brain regions most critically associated with difficulties in each of the four subtests. Complex and instrumental action deficits were associated with left precentral, postcentral, and superior parietal gyri (Brodmann areas 2, 3, 4, 5, and 6), while the facial and upper limb action deficits maps were restricted to left inferior, middle, and medial temporal gyri (Brodmann areas 20, 21, 22, and 48). We discuss ideas about neuroplasticity and cortical reorganization in chronic stroke and how different methodologies can reveal different aspects of lesion and recovery networks in apraxia.
