#### 3.2.3 Accuracy and Reliability of Wearable Devices for Stroke Rehabilitation  
Four studies examined the accuracy and reliability of wearable devices for stroke rehabilitation. One study revealed that SECOSP demonstrated superior accuracy compared to an IMU, with a mean error lower than 0.6%. It outperformed a widely used step-monitoring system, indicating its potential for precise step counting in mobility assessment [29].  
Another study showed that the SULAM system effectively monitored UE activity throughout daily routines with minimal interference. The study provided preliminary evidence of its capability to objectively evaluate rehabilitation interventions aimed at improving UE function [28].  
Another study found that participants who received high-dose accelerometer-based feedback reported significant perceived gains in both the amount and quality of paretic UE use. The feedback increased awareness of paretic limb utilization [27].  
One study demonstrated that a wireless physiological signal monitoring system effectively filtered interference and captured continuous ECG and EMG data during daily activities. The system's wireless connectivity enabled post-stroke and motor rehabilitation in home environments where standard monitoring devices were not accessible [35].  
2.4 Accuracy and Reliability of Smartphone- and Sensor-Based Solutions for Stroke Patient Rehabilitation  
One study found that SAM, unlike conventional pedometers, provides accurate and reliable measurements of cadence and total stride counts in hemiparetic stroke patients. This suggests that portable microprocessor-based gait monitoring can effectively quantify home- and community-based ambulatory activity levels in this population [26].  
One study found that using Pressure-Sensitive Bed Mats, sit-to-stand (SiSt) durations were measured and showed variations among different populations, with post-stroke adults exhibiting longer durations compared to young and elderly healthy adults. These findings provide valuable data for monitoring patients in extended-care facilities or smart home environments [30].  
A separate study showed that the SyMPATHy cup was well accepted by eight out of nine patients in rehabilitation settings or at home. These patients had minimal concerns about the design and usability of the cup, indicating its potential as an effective tool for monitoring arm and hand activity. This suggests that the cup could be a valuable tool for monitoring UE activity in rehabilitation settings [34].  
One study found that The Tentaculus System (TS), an assistive technology solution, has the potential to support individuals with cognitive impairments in their everyday activities. These technologies could become more frequently used in the near future, and the study's development process may serve as a foundation for guiding future AT implementations [31].  
One study indicated that the ijoint web application could assist medical practitioners by enabling them to monitor patient exercises, detect errors, and support the rehabilitation process through telerehabilitation tracking. Preliminary findings suggest its usefulness in treatment planning [33].
