Innovation and Digital Transformation for a Sustainable World

For the normal population, inclusion criteria consist of
individuals of both genders aged above 18 with full active
range of motion (ROM) of the upper limb of the dominant
arm. Exclusion criteria include participants with ROM
restrictions of the wrist and hand, complaints of pain, injury,
fracture, or dislocation in the dominant arm, and those
unwilling to participate.

In the case of stroke survivors, inclusion criteria include
confirmation of stroke diagnosis by a clinician and MRI/CT
report, both genders aged above 18, and being in sub-acute
(3-26 weeks) or chronic stage (>12 months) with various
ranges of supination and pronation of the forearm.
Additionally, participants should be able to sit independently
in a supported chair. Exclusion criteria encompass other

neurological disorders and musculoskeletal disorders, a Mini
Mental State Examination (MMSE) score <24, visual

Bangalore. Our goal is to orient the glass vertically during the drinking
task to prevent spills. However, there are no standardized
scales to assess drinking task performance, and existing tools
do not provide real-time feedback on glass orientation.

4.1.1 Reliability Testing

For the reliability analysis the data will be meticulously
collected on baseline characteristics such as age, gender, and
participation level of the subjects, as well as outcome
Figure 4: Development Work flow of Proposed Device measures. The intra-class correlation coefficient (ICC) will
be calculated between 10 different measurement trials.

Reliability and Concurrent validity testing involved two
phases such as;

Phase 1 consist of 96 normal individuals to establish the
reliability of the tilt sensor device.

Phase 2 consist of 96 stroke survivors will be subdivided into
6 subgroups based on specific tilt orientation of the glass
during activity.
