“…When comparing the dominant and nondominant upper limb, a highly similar muscle synergy organization was observed when performing both the virtual and real throws. Similar results were also observed in the muscle activation of healthy subjects in reaching tasks [64], in handgrip strength to grip a basketball [65], and in force and angular velocity related to the arm in baseball pitchers [66]. Conversely, difference in kinematics were noted in the dominant arm during the throwing tasks; specifically, the nondominant arm was characterized by significantly lower elbow flexion and in the external shoulder rotation at the start of the arm acceleration phase [67].…”

Virtual reality (VR) is an appealing approach for increasing the engagement and attention of patients during rehabilitation. Understanding how motor control changes in real vs. virtual scenarios is a research challenge in terms of validating its administration. This study evaluates muscle synergies when subjects conduct throwing tasks in virtual reality. Seventeen healthy subjects performed 20 throws both in a virtual environment and in real one as they threw a ball with both dominant and nondominant arms. The electromyography (EMG) signals of 11 muscles of the upper limbs were recorded. Non-negative matrix factorization was used to extract muscle synergies. The cosine similarity was computed to assess the consistence of muscle synergy organization between virtual and real tasks. The same parameter was used to establish the inter-subject similarity. A three-synergy model was selected as the most likely. No effects of virtual reality and arm side on neuromuscular organization were found. Forearm muscles, not necessary for ball holding and release, were comprised in the activation synergies in the virtual reality environment. Finally, the synergies were consistent across subjects, especially during the deceleration phase. Results are encouraging for the application of virtual reality to complement conventional therapy, improve engagement, and facilitate objective measurements of pathology progression.

“…This irregular positioning of the hand to the handlebar can include hands being positioned too widely, leading to the fingers splaying, or too much weight being placed on the hand due to the overall position. Such positioning can compress nerves, resulting in pain, numbness and weakness in flexor muscles of forearm [22] . Median nerve compression leads to numbness of the first three fingers and medial half of the fourth, while the ulnar nerve compression will affect the lateral half of the fourth finger and fifth finger entirely.…”

“…During long rides perhaps this is inconvenient. A combination of the following: numbness in the hands, elbows locked, duration-related pain in the shoulder blades, might highlight a situation in which too much weight is being put on the handlebars [22] . Hence, this might aid in the further of reduction of grip strength post cycling.…”

Recreational cycling is sort of sport that requires a decent level of endurance, and cyclists’ riding is determined by several physical abilities, in which muscular strength in upper limb is equally important as the lower limbs. While riding a bicycle, the hand grip turns out to be especially crucial not just for performance and the ability to remain upright in difficult situations and uneven surfaces but also for even moderate endurance and comfort of the rider A total of 60 recreational cyclists, 25-35 years old were included in the study. Grip strength of dominant and non-dominant hand was checked with Jamar hand held dynamometer pre cycling and was checked again after the 20km ride. Normality was checked and Dominant hand data passed the normality test thus, paired t-test was used to determine significance for (p<0.05). For Non-dominant hand readings didn’t support normality to the optimal level (p>0.05) hence non-parametric Wilcoxon signed test was used to determine significance as the samples were dependent. Mann-Whitney test was used to determine significance in Dominant and Non-Dominant hand pre cycling activity as well as comparison of Dominant and Non-Dominant hand post cycling activity, as data was not normally distributed and the samples were independent. (p>0.05). Results showed that there is significant difference in dominant as well as non-dominant hand pre and post riding activity with post cycling grip strength being reduced in both Dominant and Non-Dominant hand than the pre-cycling grip strength. Also, Dominant hand grip strength was more than the non-Dominant hand in both pre and post cycling. Key words: Recreational cyclists, Grip strength, dominant and non-dominant hand, Jamar hand held dynamometer.

Innovative wheelchair designs require new means of controlling the drive units or the propulsion transmission systems. The article proposes a signal to control the gear ratio or the amount of additional propulsion torque coming from an electric motor. The innovative control signal in this application is the signal generated by the maximum voluntary contraction (MVC) of the muscles of the upper limbs, transformed by the central processing unit (CPU) into muscle activity (MA) when using a wheelchair. The paper includes research on eight muscles of the upper limbs that are active when propelling a wheelchair. Asymmetry in the value for MVC was found between the left and right limbs, while the belly of the long radial extensor muscle of the wrist was determined to be the muscle with the least asymmetry for the users under study. This pilot research demonstrates that the difference in mean MVCmax values between the left and the right limbs can range from 20% to 49%, depending on the muscle being tested. The finding that some muscle groups demonstrate less difference in MVC values suggests that it is possible to design systems for regulating the gear ratio or additional propelling force based on the MVC signal from the muscle of one limb, as described in the patent application from 2022, no. P.440187.
