Low-cost equipment for the evaluation of reach and grasp in post-stroke individuals: a pilot study

Abstract

Background: Reach-grasp movements are motor components commonly affected after stroke and directly related to the independence of these individuals. Evaluations of these activities can be performed using clinical instruments and assessed by detailed and costly kinematic analyses. The aim of this study was to develop an analysis of reach-grasp movements in post-stroke patients using a simple, inexpensive, and manageable instrument. Results:A Mann-Whitney test was used to compare paretic and non-paretic limb motor performance. A statistically significant difference was found between the variables of total time (p = 0.02) and speed to reach target 3 (p = 0.04) for task 1, while in task 2 significance was found only in the aspect of speed to reach target 2 (p = 0.04). The correlation between clinical tests and variables of tasks was then performed using Spearman's rank correlation coefficient. At task 1, when compared with the REACH instrument, the close target sub-item; there was a high positive correlation between the parameters of total time (p = 0.028), target velocity 3 (p = 0.028), and target acceleration 3 (p = 0.028). Another instrument that showed a high positive correlation with the target time 3 (p = 0.01) and target acceleration 3 (p = 0.028) variables was the Box and Block Test. When correlated, the data between the task 2 variables and clinical instruments did not present statistically significant data. Conclusion:Our instrument-the Temporal Data Acquisition Instrument-TDAIfulfilled the expected objectives and can be used as an option to evaluate the movements of reach and grasp of upper limb post-stroke, using an easy and fast application, without the need for calibration. retrospectively registered (http:// www.ensai oscli nicos .gov.br/rg/RBR-4995c r/)

The Correlation Between Reach and Grasp Kinematic Measures and Clinical Measures of Manual Dexterity in Patients With Parkinson Disease

“…The significant correlation between upper limb kinematic measures and clini- cal measures of manual dexterity (i.e. BBT and NHPT) has been previously reported in other neurological disorders than PD [9,11,24]. This is the first study, to the best of authors' knowledge, which investigated the correlation between reach and grasp kinematic measures and manual dexterity in patients with PD.…”

“…normalized speed) and BBT score in stroke survivors [9]. Gomes et al (2020) also reported a significant correlation between movement time in a reach and grasp task and gross manual dexterity assessed by the BBT in stroke survivors [11]. A significant correlation between kinematic measure (i.e.…”

“…Although it seems that laboratory measures such as kinematic parameters determined by motion analysis system are more representative of motor control strate-gies, only a few studies have evaluated the relationship between upper limb kinematic parameters and clinical data. Also these studies were limited to the subjects with stroke [9][10][11]. Only recently, Garza Rodriguez et al reported a significant correlation between kinematic measures of supination and pronation and clinical assessment of supination/pronation using item 3.6 of the Unified Parkinson's Disease Rating Scale (UPDRS) [12].…”

Effects of attentional focus on upper extremity motor performance in post stroke patients

“…The participants performed the same tasks, irrespective of the group they belonged to and the study phase, according to the protocol of the Temporal Data Acquisition Instrument (TDAI). [ 21 ] Both tasks were performed with the patient sitting, with the back supported and the trunk without restrictions, facing an adjustable-height table, and the elbow positioned at 90° flexion, shoulder at 0°, and hands on the table (demarcated point). TDAI was positioned in front of the participant at a distance equivalent to 90% of the arm length (distance measured between the axillary line and the sternum styloid process) (Fig.…”

Application of Attention Focus in Rehabilitation to Promote Motor Performance and Motor Learning

“…Gomes et al [60] examined the effects of attention focus during upper limb tasks performed by patients with stroke. The temporal data acquisition instrument (TDAI) [61], an upper limb function test for patients with stroke, was used. The patients' upper limb movements were captured using a camera, and the upper limb movement time, speed, and peak speed were calculated.…”
