Motor Coordination and Grip Strength of the Dominant and Non-Dominant Affected Upper Limb Depending on the Body Position—An Observational Study of Patients after Ischemic Stroke

Abstract

Stroke is one of the leading causes of human disability globally. Motor function deficits resulting from a stroke affect the entire body, but relatively often it is the upper limbs that remain ineffective, which is very limiting in everyday life activities. The finding in neurorehabilitation that trunk control contributes to upper limb function is relatively common but has not been confirmed in clinical trials. This observational prospective study aims to analyze the effect of the position of the trunk and the affected upper limb on the coordination and grip strength of the affected dominant and non-dominant hand and wrist in people after ischemic stroke. The research was carried out at the Department of Neurological Rehabilitation, on a group of 60 patients with acute ischemic stroke. A Hand Tutor device and a hand dynamometer were used for the main measurements of the motor coordination parameters (maximum range of motion, frequency of movement) and the grip strength of the dominant and non-dominant upper limb. The patients were examined in two positions: sitting without back support and lying on the back with stabilization of the upper limb. Higher and relevant results were observed in the non-dominant hand, in the supine position in terms of motor coordination parameters of the fingers (p = 0.019; p = 0.011) and wrist (p = 0.033), and grip strength (p = 0.017). Conclusions: The laying position and stabilization of the affected upper limb in the acute phase following ischemic stroke is more beneficial for the coordination of movements and grip strength of the non-dominant hand.

Change in the Results of Motor Coordination and Handgrip Strength Depending on Age and Body Position—An Observational Study of Stroke Patients and Healthy Volunteers

“…In the cited study, the results show that there are objective differences in the sensorimotor function due to age, and the differences are greater in the case of the dominant arm [39]. On the other hand, in another study, the analysis of the stable and unstable position for the examination of the affected dominant and non-dominant hand of the patient after a stroke showed that the stable position is more beneficial for achieving better motor coordination parameters, especially in the case of the non-dominant limb [40]. In our current study, the dominant hand was tested 100% in a group of healthy volunteers, and they achieved higher results than in patients.…”

Effects of powerball on grip strength in children with developmental delay

“…Milestones cannot be easily measured below the age of 3 years, due to which the prevalence of low to severe symptpms can be seen in these children (Sternäng et al, 2015). Physical exertion level is directly connected to the muscle strength of most organisms but especially in all human beings, as good and well coordinated muscle movement can make life easier (Olczak & Truszczyńska-Baszak, 2022;Valenzuela & Varacallo, 2018). Compromised grip strength can make the children unable to fulfill their daily tasks while improvement in body functions,position of elbow and muscle strength can improve the manual dexterity, grip strength and fine motor skills which will help them to perform the daily activities of life (Demirci & Kartal, 2018).…”

Association of Braden scale and subscale scores of patients with and without open wound pressure ulcers

“…According to a research, PU is caused by physical elements such as shearing forces, friction, and dampness (2). Long periods of sitting or lying in the same position without moving can cause ischemia and necrosis of the skin and underlying tissues in patients with neurological problems (3). Other triggering variables, including as obesity, diabetes mellitus, ageing, lowered immunity, dietary inadequacies, and co-morbidities, increase the susceptibility of these patients (4).…”
