Deficit in sustained attention during the subacute phase following a stroke: management in a hospital setting
Sustained attention is one of the cognitive functions most frequently impaired following a stroke, particularly during the subacute phase. In the hospital setting, this deficit has direct implications for patient engagement in therapy, safety, and the potential for functional recovery.
Despite its importance, its implementation is often limited by structural constraints within the healthcare setting itself: limited clinical time, high patient variability, and difficulty in maintaining an adequate level of therapeutic intensity.
This article examines, from a clinical perspective, how to understand and treat subacute sustained attention deficit in a hospital setting, including the role of digital tools in optimizing treatment.

Characteristics of the subacute phase in brain injury
Recovery window
The subacute phase, which spans roughly from the first few days to the first few months following a stroke, is characterized by high neural plasticity. During this period, the nervous system exhibits a greater capacity for reorganization, making this phase a critical time for cognitive intervention.
However, this therapeutic opportunity is accompanied by significant clinical instability, both neurologically and behaviorally.
Clinical limitations of the hospital setting
Working in a hospital setting presents specific challenges:
- Short-term therapy sessions
- Frequent interruptions (medical tests, care)
- Daily fluctuations in the patient’s condition
- Environments with uncontrolled distractors
These factors make it difficult to implement structured cognitive rehabilitation programs unless they are specifically tailored to this context.
Impairments in sustained attention during this phase
Decreased vigilance
It is common to observe a reduction in the patient’s ability to sustain their attention over time. This results in a rapid decline in performance on repetitive or monotonous tasks.
Yield fluctuations
One of the most characteristic features of the subacute phase is intra-individual variability. The same patient may exhibit widely varying performance depending on the time of day, the level of fatigue, or the cognitive load.
The Impact of Fatigue and Cognitive Load
Cognitive fatigue sets in early, even when attention demands are low. This affects both the duration of tasks and the ability to learn during the intervention.
Functional consequences in hospitalized patients
Participation in therapy
A deficit in sustained attention directly limits the patient’s ability to engage in physical therapy, occupational therapy, or speech therapy sessions. The lack of sustained attention reduces the effectiveness of any intervention.
Clinical safety
A decline in alertness is associated with an increased risk of errors, oversights, and unsafe behaviors, including falls or failure to follow instructions properly.
Principles of Intervention in a Hospital Setting
Brief and frequent interventions
In the subacute phase, it is more effective to structure multiple short-duration interventions than to conduct long sessions. This allows for better adaptation to cognitive fatigue and helps maintain a minimum level of attentional quality.
Low initial cognitive load
Tasks should start with low expectations, prioritizing consistency of performance over complexity. The initial goal is not to challenge the patient, but to maintain their attention.
Environmental control
Whenever possible, distractions (noise, interruptions, irrelevant stimuli) should be minimized. In a hospital setting, this is not always feasible, which makes the design of the task even more important.
Limitations of the traditional approach on the ward
Limited clinical time
The time available per patient is often insufficient to achieve a therapeutically effective dose in terms of cognitive function.
Low therapeutic intensity
Interventions based exclusively on in-person sessions tend to be less intensive, which limits the potential for bringing about significant changes in skills such as sustained attention.
Furthermore, patient variability makes it difficult to maintain a structured progression without tools that allow for flexible adjustments to the intervention.
The Role of Digital Support in the Subacute Phase
The use of digital tools makes it possible to overcome some of the structural limitations of the hospital environment.
Increase in the therapeutic dose
Digital platforms make it easier to perform additional tasks outside of strictly supervised hours, increasing the intensity of the intervention without adding to the professional’s workload.
Standardization of tasks
They allow tasks to be administered with controlled parameters (duration, stimulus frequency, type of response), which improves the consistency of the intervention.
Customized adjustment
The clinician can quickly adjust the difficulty or characteristics of the task based on the patient’s performance, which is particularly important during a phase characterized by high variability.
In this context, solutions such as Rehametrics make it possible to integrate cognitive intervention into the hospital care workflow, facilitating both the implementation and monitoring of tasks.
Clinical conclusions
Impaired sustained attention in the subacute phase following a stroke is a key limiting factor in the functional recovery of hospitalized patients.
This approach requires:
- Adaptation to the hospital setting
- Brief, structured, and repeated interventions
- Managing Cognitive Load
- Continuous adjustment based on performance
Digital support does not replace clinical care, but it does allow for greater intensity, precision, and adaptability in treatment—all of which are critical during this phase of recovery.
