SUMMARY:

Introduction: Stroke results in a range of neurological impairments
that compromise the patients’ functional capacity. Objective: To carry
out an analysis of the functional movement of the upper limb in the
activity of drinking water, in order to identify motor changes according to the side of the hemiparesis. Methods: The sample consisted of 12
post-stroke patients, 6 with right hemiparesis (RP) and 6 with left
hemiparesis (LP), and 12 healthy individuals, of whom 6 performed the
activity with the right hand (RH) and 6 with the left hand (LH).
Participants were submitted to a kinematic assessment of the activity of
drinking water by the Qualisys System, which included reaching for
and grasping the glass, transporting it to the mouth, returning the glass
to the table, and repositioning the hand to the initial location. Shoulder
and elbow angles were calculated along the frames (time fractions).
Data were analyzed using the Student’s t-test (p<0.05) and Pearson’s
correlation coefficient. Results: A significant difference was observed
between RP and LP in the shoulder angles in frames 9 to 14 (p<0.05),
corresponding to the initial phase of reaching the cup, and at frame 91,
at the end of the return of the cup to the cup table (p=0.039), with the
LP group presenting lower angulation. There was no difference
between the RP and LP groups in the elbow angles (p>0.05) and in the
shoulder angles between RH and LH (p>0.05). A significant difference
was observed in elbow angles between RH and LH in frames 22 to 31
(p<0.05), with the SD group presenting greater angle in the cup
reaching phase. Atypical correlation patterns between shoulder and
elbow angles were observed in RP and LP patients, indicating impaired
motor coordination. Trajectory analysis revealed impaired motor
control during specific phases of the drinking task, particularly in the
LP group during the initial movement of bringing the glass to the
mouth. Conclusion: The present study demonstrates that a kinematic
evaluation of the drinking task allows the identification of distinct
spatiotemporal alterations in shoulder and elbow movements patterns,
depending on the side of the cerebral lesion in post-stroke patients.
These results highlight the need for tailored planning in
neurorehabilitation strategies.
