A taxonomy of business models of digital care platforms in Spain

AbstractIn the last few years, the proliferation of digital labour platforms has led to the transformation of business models and labour relations in an increasing number of economic activities, including highly feminized and informal traditional sectors, such as care and domestic work. Drawing on an analysis of 37 digital care platforms in Spain, this research compares the distinctive features and structural power dynamics they engender, and it constructs a taxonomy of business models of these care platforms. By analysing the main features of their operational models, we are capable of distinguishing three main types of platforms: marketplace, on‐demand, and digital placement agencies. First, the paper argues that the distinctive features of each digital platform business model have differentiated impacts on working conditions in terms of access to tasks, remuneration, flexibility and means of control. This differentiation allows us to understand what is transformative and what is continuous in platforms' precarization or formalisation of care work and working conditions of carers, mainly women and migrants. Each business model has its differentiated outcomes in terms of labour control and reorganization of women's and migrants' reproductive work. Second, more broadly, while digital care platforms may have contributed to facilitating workers' access to jobs, reducing transaction costs and standardising processes, this has often been through the creation of more flexible and insecure forms of work and to increased market pressures. Therefore, this study contributes to existing research addressing the degree of formalization of labour relations in digital platform work through a nuanced analysis of their business models.

Pelaksanaan Event Sponsorship Sebagai Implementasi Komunikasi Pemasaran Produk By.U Oleh Telkomsel Branch Surabaya

Currently, there are many internet providers in Indonesia that offer various benefits, such as digital providers. Demand for the internet continues to increase every year. by.U is the first digital provider in Indonesia targeting the millennial or Gen Z demographic, which has attracted researchers' interest in conducting further research about the company. Researchers used a qualitative approach known as a case study which aims to study the marketing communication methods and promotional mix used by Telkomsel to promote by.U cards to the youth market. Interviews, documentation of event implementation, and observations were carried out to collect data. The data processing method used by the author is descriptive. A brief description and analysis of data collected from various sources, both direct and indirect, is presented previously. The focus of this research is the process of implementing marketing communications by the by.U. company, the data for which was collected through interviews and observation. After that, the data will be analyzed in three stages: data reduction, data presentation, and conclusion drawing. Marketing communications used by event sponsors to increase sales of by.U products consist of sales promotions, personal sales and direct marketing. This research shows that by.U controls its marketing communications by using social media, influencers, and digital placements to make customers want to buy its products. In this research, marketing communication strategies include digital placement and influencer marketing.

Digital clinical placements: Student perspectives and preparedness for placements.

In May 2020, first-year students at Imperial College School of Medicine attended a 'digital hospital placement'. Occurring in the early months of the COVID-19 pandemic, this replaced their first planned hospital placement. The authors analysed student experiences to understand how a digital hospital placement impacted self-perceived clinical and professional development and whether it improved preparedness for face-to-face hospital placements. Three hundred ten students participated in this week-long digital placement, which integrated clinical skills, communication and professional behaviour domains. It aimed to prepare students for safe participation in clinical environments. Resources included self-directed and peer learning, virtual simulations (Oxford Medical Simulation) and staff-led debriefing. Surveys were administered after the digital placement and after students' first face-to-face placement to collect quantitative and qualitative data. A reflexive thematic analysis was conducted. Eighty-three and twenty-nine students completed the postdigital and post-face-to-face placement evaluation respectively. Quantitative results indicated a high self-rated achievement of learning objectives and enthusiasm for digital placements; 83% of respondents supported digital simulations as part of regular medical education. Qualitative analysis identified three superordinate themes: (1) domain integration in digital placements helped students feel better prepared; (2) digital experiential learning is ideally suited to early clinical learning; and (3) virtual placements are a compliment, not an alternative, to face-to-face placements. Digital placements are a promising means of supporting the challenging transition from classroom learner to clinical learner. They provide a feasible and scalable option for building student confidence and improving preparedness.

The functional connectivity and neuropsychology underlying mental planning operations: data from the digital clock drawing test.

We examined the construct of mental planning by quantifying digital clock drawing digit placement accuracy in command and copy conditions, and by investigating its underlying neuropsychological correlates and functional connectivity. We hypothesized greater digit misplacement would associate with attention, abstract reasoning, and visuospatial function, as well as functional connectivity from a major source of acetylcholine throughout the brain: the basal nucleus of Meynert (BNM). Participants (n = 201) included non-demented older adults who completed all metrics within 24 h of one another. A participant subset met research criteria for mild cognitive impairment (MCI; n = 28) and was compared to non-MCI participants on digit misplacement accuracy and expected functional connectivity differences. Digit misplacement and a comparison dissociate variable of total completion time were acquired for command and copy conditions. a priori fMRI seeds were the bilateral BNM. Command digit misplacement is negatively associated with semantics, visuospatial, visuoconstructional, and reasoning (p’s < 0.01) and negatively associated with connectivity from the BNM to the anterior cingulate cortex (ACC; p = 0.001). Individuals with MCI had more misplacement and less BNM-ACC connectivity (p = 0.007). Total completion time involved posterior and cerebellar associations only. Findings suggest clock drawing digit placement accuracy may be a unique metric of mental planning and provide insight into neurodegenerative disease.

Using virtual reality for anatomical landmark annotation in geometric morphometrics.

To study the shape of objects using geometric morphometrics, landmarks are oftentimes collected digitally from a 3D scanned model. The expert may annotate landmarks using software that visualizes the 3D model on a flat screen, and interaction is achieved with a mouse and a keyboard. However, landmark annotation of a 3D model on a 2D display is a tedious process and potentially introduces error due to the perception and interaction limitations of the flat interface. In addition, digital landmark placement can be more time-consuming than direct annotation on the physical object using a tactile digitizer arm. Since virtual reality (VR) is designed to more closely resemble the real world, we present a VR prototype for annotating landmarks on 3D models. We study the impact of VR on annotation performance by comparing our VR prototype to Stratovan Checkpoint, a commonly used commercial desktop software. We use an experimental setup, where four operators placed six landmarks on six grey seal (Halichoerus grypus) skulls in six trials for both systems. This enables us to investigate multiple sources of measurement error. We analyse both for the configuration and for single landmarks. Our analysis shows that annotation in VR is a promising alternative to desktop annotation. We find that annotation precision is comparable between the two systems, with VR being significantly more precise for one of the landmarks. We do not find evidence that annotation in VR is faster than on the desktop, but it is accurate.

3 The Implementation of Simulated Placements in Undergraduate Healthcare Courses During the Covid-19 Pandemic

In 2020 many healthcare students lost placement hours due to COVID-19. In response to this crisis, simulated placements were implemented to ensure students were able to achieve their practice hours. A pilot project was undertaken in November 2020. This was then developed at pace into a simulated placement module that could accommodate around 3,500 students by the start of January 2021. Nursing and Midwifery Council guidance was updated in February 2021 The study aimed to enable nursing students to maintain their hours as required by the NMC, and provide evidence to demonstrate achievement of their competencies. It also aimed to ensure patients and service users from all fields were represented within the activities.A module blackboard site was developed online to house the materials. Each activity was mapped to the cohort-specific proficiencies which needed to be achieved for that particular level of study (BSc and MSc). A wide range of activities were included such as Oxford Medical Simulation, detailed case studies and scenarios including ‘talking head’ style videos and patient documentation, service user interviews, analysing Care Opinion patient feedback, and 360-degree tours of a patient’s home to undertake a risk assessment.Students were able to access the simulated placements if waiting for a clinical placement due to lack of availability, if course completion was delayed due to ‘opting out’, or if the student was self-isolating or shielding. Students received comprehensive guidance as well as regular YouTube updates to walk them through the process. A mixture of live online sessions and self-directed activities were included and engagement was logged on a placement timesheet. There were also activities and live sessions focussing on student well-being and preparation for placements. It was also important to include activities focussing on other fields of nursing such as mother and baby or learning disabilities. A reflection was then uploaded to the digital placement assessment document so that it could be accessed virtually by the practice assessor and academic assessor. The simulated placements have since expanded into the Allied Health Professional courses within the university and it has been valuable to undertake interprofessional resource sharing to further enhance the simulated placements experience.

Anticipatory Motor Planning and Control of Grasp in Children with Unilateral Spastic Cerebral Palsy.

Children with unilateral spastic cerebral palsy (USCP) have impairments in motor planning, impacting their ability to grasp objects. We examined the planning of digit position and force and the flexibility of the motor system in covarying these during object manipulation. Eleven children with a left hemisphere lesion (LHL), nine children with a right hemisphere lesion (RHL) and nine typically developing children (controls) participated in the study. Participants were instructed to use a precision grip with their dominant/less affected hand to lift and keep an object level, with either a left, centered or right center of mass (COM) location. Digit positions, forces, compensatory torque and object roll where measured. Although children with USCP generated a compensatory torque and modulated digit placement by lift-off, their index finger was either collinear or higher than the thumb, regardless of COM location, leading to larger rolls after lift-off especially for the RHL group. The findings suggest that while the kinetics of grasp control is intact, the kinematics of grasp control is impaired. This study adds to the understanding of the underlying mechanisms of anticipatory planning and control of grasp in children with USCP and may provide insights on how to improve hand function in children with USCP.

Digital placement system of a lateral tensioning rod during the formation of flexible-oriented three-dimensional composite preforms

The placement of a lateral tensioning rod is the main event during the formation of a flexible-oriented three-dimensional composite preform. Inaccurate placement can result in defective fiber weaving, degrading the overall quality of the preform. Furthermore, the manual execution of this task is time-consuming and ineffective. In this study, an automatic and digital placement method and mechanism are proposed to address these problems for the first time. In particular, an image processing method is proposed to recognize the placement region, where the geometric features are irregular and the feature differences are neglectable compared to the background. The placement position is then detected using a single industrial endoscope and the similar decision theorem of triangles. Furthermore, the proposed method and mechanism are applied to a digital placement system. The lateral tensioning rod can be accurately placed, as the relative error between the actual and ideal placement positions is within 0.5 %. The proposed method, therefore, automatizes the manual task and is essential in the development of preform formation toward digital manufacturing.

Normative References for Graphomotor and Latency Digital Clock Drawing Metrics for Adults Age 55 and Older: Operationalizing the Production of a Normal Appearing Clock.

Relative to the abundance of publications on dementia and clock drawing, there is limited literature operationalizing 'normal' clock production. To operationalize subtle behavioral patterns seen in normal digital clock drawing to command and copy conditions. From two research cohorts of cognitively-well participants age 55 plus who completed digital clock drawing to command and copy conditions (n = 430), we examined variables operationalizing clock face construction, digit placement, clock hand construction, and a variety of time-based, latency measures. Data are stratified by age, education, handedness, and number anchoring. Normative data are provided in supplementary tables. Typical errors reported in clock research with dementia were largely absent. Adults age 55 plus produce symmetric clock faces with one stroke, with minimal overshoot and digit misplacement, and hands with expected hour hand to minute hand ratio. Data suggest digitally acquired graphomotor and latency differences based on handedness, age, education, and anchoring. Data provide useful benchmarks from which to assess digital clock drawing performance in Alzheimer's disease and related dementias.

Manipulation of physical 3-D and virtual 2-D stimuli: comparing digit placement and fixation position.

The visuomotor processes involved in grasping a 2-D target are known to be fundamentally different than those involved in grasping a 3-D object, and this has led to concerns regarding the generalizability of 2-D grasping research. This study directly compared participants' fixation positions and digit placement during interaction with either physical square objects or 2-D virtual versions of these objects. Participants were instructed to either simply grasp the stimulus or grasp and slide it to another location. Participants' digit placement and fixation positions did not significantly differ as a function of stimulus type when grasping in the center of the display. However, gaze and grasp positions shifted toward the near side of non-central virtual stimuli, while consistently remaining close to the horizontal midline of the physical stimulus. Participants placed their digits at less stable locations when grasping the virtual stimulus in comparison to the physical stimulus on the right side of the display, but this difference disappeared when grasping in the center and on the left. Similar outward shifts in digit placement and lowered fixations were observed when sliding both stimulus types, suggesting participants incorporated similar adjustments in grasp selection in anticipation of manipulation in both Physical and Virtual stimulus conditions. These results suggest that while fixation position and grasp point selection differed between stimulus type as a function of stimulus position, certain eye-hand coordinated behaviours were maintained when grasping both physical and virtual stimuli.

Role of Tactile Noise in the Control of Digit Normal Force.

Whenever we grasp and lift an object, our tactile system provides important information on the contact location and the force exerted on our skin. The human brain integrates signals from multiple sites for a coherent representation of object shape, inertia, weight, and other material properties. It is still an open question whether the control of grasp force occurs at the level of individual fingers or whether it is also influenced by the control and the signals from the other fingers of the same hand. In this work, we approached this question by asking participants to lift, transport, and replace a sensorized object, using three- and four-digit grasp. Tactile input was altered by covering participant's fingertips with a rubber thimble, which reduced the reliability of the tactile sensory input. In different experimental conditions, we covered between one and three fingers opposing the thumb. Normal forces at each finger and the thumb were recorded while grasping and holding the object, with and without the thimble. Consistently with previous studies, reducing tactile sensitivity increased the overall grasping force. The gasping force increased in the covered finger, whereas it did not change from baseline in the remaining bare fingers (except the thumb for equilibrium constraints). Digit placement and object tilt were not systematically affected by rubber thimble conditions. Our results suggest that, in each finger opposing thumb, digit normal force is controlled locally in response to the applied tactile perturbation.

Proof of concept: digital clock drawing behaviors prior to transcatheter aortic valve replacement may predict length of hospital stay and cost of care.

Aims:Reduced pre-operative cognitive functioning in older adults is a risk factor for postoperative complications, but it is unknown if preoperative digitally-acquired clock drawing test (CDT) cognitive screening variables, which allow for more nuanced examination of patient performance, may predict lengthier hospital stay and greater cost of hospital care. This issue is particularly relevant for older adults undergoing transcatheter aortic valve replacement (TAVR), as this surgical procedure is chosen for intermediate-risk older adults needing aortic replacement. This proof of concept research explored if specific latency and graphomotor variables indicative of planning from digitally-acquired command and copy clock drawing would predict post-TAVR duration and cost of hospitalization, over and above age, education, American Society of Anesthesiologists (ASA) physical status classification score, and frailty.Methods:Form January 2018 to December 2019, 162 out of 190 individuals electing TAVR completed digital clock drawing as part of a hospital wide cognitive screening program. Separate hierarchical regressions were computed for the command and copy conditions of the CDT and assessed how a-priori selected clock drawing metrics (total time to completion, ideal digit placement difference, and hour hand distance from center; included within the same block) incrementally predicted outcome, as measured by R2 change significance values.Results:Above and beyond age, education, ASA physical status classification score, and frailty, only digitally-acquired CDT copy performance explained significant variance for length of hospital stay (9.5%) and cost of care (8.9%).Conclusions:Digital variables from clock copy condition provided predictive value over common demographic and comorbidity variables. We hypothesize this is due to the sensitivity of the copy condition to executive dysfunction, as has been shown in previous studies for subtypes of cognitive impairment. Individuals undergoing TAVR procedures are often frail and executively compromised due to their cerebrovascular disease. We encourage additional research on the value of digitally-acquired clock drawing within different surgery types. Type of cognitive impairment and the value of digitally-acquired CDT command and copy parameters in other surgeries remain unknown.

A Communication-Aware DNN Accelerator on ImageNet Using In-Memory Entry-Counting Based Algorithm-Circuit-Architecture Co-Design in 65-nm CMOS

This article presents a communication-aware processing-in-memory deep neural network accelerator, which implements an in-memory entry-counting scheme for low bit-width quantized multiplication-and-accumulations (MACs). To maintain good accuracy on ImageNet, the proposed design adopts a full-stack co-design methodology, from algorithms, circuits to architectures. In the algorithm level, an entry-counting based MAC is proposed to fit the learned step-sized quantization scheme, and exploit the sparsity of both activations and weights intrinsically. In the circuit level, content addressable memory cells and multiplexed arrays are developed in the processing-in-memory macro. In the architecture level, the proposed design is compatible with different stationary dataflow mappings, further reducing the memory access. An in-memory entry-counting silicon prototype and its entire peripheral circuits are fabricated in 65nm LP CMOS technology with an active area of $0.76\times 0.66$ mm2. The 7.36-Kb processing-in-memory macro with 128 search entries can reduce the multiplication number by $12.8\times $ . The peak throughput is 3.58 GOPS, achieved at a clock rate of 143MHz and a power supply of 1.23V. The peak energy efficiency of the processing-in-memory macro is 11.6 TOPS/W, achieved at a clock rate of 40MHz and a power supply of 1.01V. Note that the physical design of the entry-counting memory is completed in a standard digital placement and routing flow by augmenting the library with two dedicated memory cells. A 3-bit quantized ResNet-18 on the ImageNet dataset is performed, where the top-1 accuracy is 64.4%.

Grasping a 2D virtual target: The influence of target position and movement on gaze and digit placement.

While much has been learned about the visual pursuit and motor strategies used to intercept a moving object, less research has focused on the coordination of gaze and digit placement when grasping moving stimuli. Participants grasped 2D computer generated square targets that either encouraged placement of the index finger and thumb along the horizontal midline (Control targets) or had narrow "notches" in the top and bottom surfaces of the target, intended to discourage digit placement near the midline (Experimental targets). In Experiment 1, targets remained stationary at the left, middle, or right side of the screen. Gaze and digit placement were biased toward the closest side of non-central targets, and toward the midline of center targets. These locations were shifted rightward when grasping Experimental targets, suggesting participants prioritized visibility of the target. In Experiment 2, participants grasped horizontally translating targets at early, middle, or late stages of travel. Average gaze and digit placement were consistently positioned behind the moving target's horizontal midline when grasping. Gaze was directed farther behind the midline of Experimental targets, suggesting the absence of a flat central grasp location pulled participants' gaze toward the trailing edge. Participants placed their digits at positions closer to the horizontal midline of leftward moving targets, suggesting participants were compensating for the added mechanical constraints associated with grasping targets moving in a direction contralateral to the grasping hand. These results suggest participants minimize the effort associated with reaching to non-central targets by grasping the nearest side when the target is stationary, but grasp the trailing side of moving targets, even if this means placing the digits at locations on the far side of the target, potentially limiting visibility of the target.

Assessment of Adequacy of Oxytocin Use in Pregnant Women Undergoing Induction of Labor [OP03-4C

INTRODUCTION: Evaluation of adequacy of intrapartum management often includes quantification of oxytocin use, such as maximum rate of oxytocin used or length of time on oxytocin. Our objective was to evaluate a calculated measure that combines rate and time of oxytocin and its relationship with mode of delivery. METHODS: This is a secondary analysis of a randomized trial comparing speculum vs digital placement of Foley balloon for cervical ripening. Trial participants who did not receive oxytocin were excluded. Total dose of oxytocin received (OXYTOT) was calculated as the sum of the product of oxytocin rate and time on that rate for each concentration used. Area under the curve (AUC) was determined. Receiver operator characteristic (ROC) curves, and Wilcoxon rank sum test were used for analysis. OXYTOT was also categorized into deciles and its relationship to rate of cesarean section (CS) was studied. RESULTS: This analysis included 368 patients. Patients’ characteristics were similar in both CS and vaginal delivery (VD) groups. OXYTOT was predictive of mode of delivery (AUC of 0.62 95% CI 0.55-0.69). Women who underwent CS had a significant higher OXYTOT compared to women who had VD (9,308 vs 6,307 mIU, P&lt;.0001). Rate of CS started significantly increasing at the 7th decile of OXYTOT (8,120 mIU). CONCLUSION: OXYTOT is a useful measure to assess adequacy of oxytocin use in induction of labor. CS rate remains low until high levels of this measure are reached. This measure may be a useful adjunct in assessing the quality of induction of labor and monitoring CS rates.

309: Foley balloon insertion by blind placement versus direct visualization: A randomized controlled trial (FRIENDLY)

To test the hypothesis that digital placement of a balloon catheter is not inferior to the speculum method in terms of rate of maternal infection. Pregnant women >37 weeks undergoing induction of labor with unfavorable cervix (< 3 cm and < 60% effaced) were randomly assigned to balloon catheter placed either digitally (DP) or using a sterile speculum (SS). The cervix was cleaned with Betadine before insertion in the SS group. The balloon was inflated with 60 mL of sterile saline and left up to 12 hours. If the cervix remained unfavorable, one more round of balloon ripening was performed. All other management, including the use of oxytocin, was left to the discretion of the clinical providers. The primary outcome was a composite of maternal infection, defined by occurrence of fever, chorioamnionitis, or endometritis. Secondary outcomes are listed in Table. Patients completed a satisfaction survey. On the basis of a non-inferiority margin of 10% and an expected primary outcome frequency of 10%, a sample size of 372 women was needed (90% power to confirm non-inferiority with 90% protocol adherence). 372 women were randomized (185 digital, 187 speculum). Composite maternal infection rate was higher in the digital arm (15.7% vs. 12.8%), with an absolute difference with respect to the speculum arm of 2.8% (95% CI -4.3% to 9.9%), indicating non-inferiority for the pre-specified margin (Figure). Secondary outcomes were not different between groups, except for higher need for a second balloon catheter in the speculum arm (Table). Maternal and neonatal adverse events and responses on the satisfaction survey were not different between groups. Digital placement of a balloon catheter for pre-induction cervical ripening is non-inferior to the sterile-speculum method in terms of maternal infection. Women in the sterile speculum group required a second round of the mechanical dilator more frequently. The blind digital approach is a reasonable option for balloon placement for cervical ripening.View Large Image Figure ViewerDownload Hi-res image Download (PPT)

Clock Drawing Performance Slows for Older Adults After Total Knee Replacement Surgery.

Clock drawing is a neurocognitive screening tool used in preoperative settings. This study examined hypothesized changes in clock drawing to command and copy test conditions 3 weeks and 3 months after total knee arthroplasty (TKA) with general anesthesia. Participants included 67 surgery and 66 nonsurgery individuals >60 years who completed the digital clock drawing test before TKA (or a pseudosurgery date), and 3 weeks and 3 months postsurgery. Generalized linear mixed models assessed digital clock drawing test latency (ie, total time to completion, seconds between digit placement) and graphomotor output (ie, total number of strokes, clock size). Reliable change analyses examined the percent of participants showing change beyond differences found in nonsurgery peers. After adjusting for age, education, and baseline cognition, both digital clock drawing test latency measures were significantly different for surgery and nonsurgery groups, where the surgery group performed slower on both command and copy test conditions. Reliable change analyses 3 weeks after surgery found that total time to completion was slower among 25% of command and 21% of copy constructions in the surgery group. At 3 months, 18% of surgery participants were slower than nonsurgery peers. Neither graphomotor measure significantly changed over time. Clock drawing construction slowed for nearly one-quarter of patients after TKA surgery, whereas nonsurgery peers showed the expected practice effect, ie, speed increased from baseline to follow-up time points. Future research should investigate the neurobiological basis for these changes after TKA.

Hand forces and placement are modulated and covary during anticipatory control of bimanual manipulation.

Dexterous object manipulation relies on the feedforward and feedback control of kinetics (forces) and kinematics (hand shaping and digit placement). Lifting objects with an uneven mass distribution involves the generation of compensatory moments at object lift-off to counter object torques. This is accomplished through the modulation and covariation of digit forces and placement, which has been shown to be a general feature of unimanual manipulation. These feedforward anticipatory processes occur before performance-specific feedback. Whether this adaptation is a feature unique to unimanual dexterous manipulation or general across unimanual and bimanual manipulation is not known. We investigated the generation of compensatory moments through hand placement and force modulation during bimanual manipulation of an object with variable center of mass. Participants were instructed to prevent object roll during the lift. Similar to unimanual grasping, we found modulation and covariation of hand forces and placement for successful performance. Thus this motor adaptation of the anticipatory control of compensatory moment is a general feature across unimanual and bimanual effectors. Our results highlight the involvement of high-level representation of manipulation goals and underscore a sensorimotor circuitry for anticipatory control through a continuum of force and placement modulation of object manipulation across a range of effectors. NEW & NOTEWORTHY This is the first study, to our knowledge, to show that successful bimanual manipulation of objects with asymmetrical centers of mass is performed through the modulation and covariation of hand forces and placements to generate compensatory moments. Digit force-to-placement modulation is thus a general phenomenon across multiple effectors, such as the fingers of one hand, and both hands. This adds to our understanding of integrating low-level internal representations of object properties into high-level task representations.

Sensorimotor uncertainty modulates corticospinal excitability during skilled object manipulation.

Sensorimotor memory built through previous hand-object interactions allows subjects to plan grasp forces. The memory-based mechanism is particularly effective when contact points on the object do not change across multiple manipulations, thus allowing subjects to generate the same forces in a feedforward fashion. However, allowing subjects to choose where to grasp an object causes trial-to-trial variability in fingertip positioning, suggesting a decreased ability to predict where the object will be grasped. In this scenario, subjects modulate forces on a trial-to-trial basis as a function of fingertip positioning. We suggested that this fingertip force-to-position modulation could be implemented by transforming feedback of digit placement into an accurate distribution of fingertip forces. Thus, decreasing certainty of fingertip position on an object would cause a shift from predominantly memory- to feedback-based force control mechanisms. To gain further insight into these sensorimotor transformation mechanisms, we asked subjects to grasp and lift an object with an asymmetrical center of mass while preventing it from tilting. To isolate the effect of digit placement uncertainty, we designed two experimental conditions that differed in terms of predictability of fingertip position but had similar average fingertip positioning and force distribution. We measured corticospinal excitability to probe possible changes in sensorimotor processing associated with digit placement uncertainty. We found a differential effect of sensorimotor uncertainty after but not before object contact. Our results suggest that sensorimotor integration is rapidly tuned after object contact based on different processing demands for memory versus feedback mechanisms underlying the control of manipulative forces.NEW & NOTEWORTHY The relative contribution of predictive and feedback mechanisms for scaling digit forces to position during dexterous manipulation depends on the predictability of where the object will be grasped. We found that corticospinal excitability shortly after contact was sensitive to digit position predictability. This supports the proposition that distinct sensorimotor integration processes are engaged, depending on the role of feedback about digit placement versus sensorimotor memory in controlling manipulative forces.
