This paper presents the elbow flexion and extension rehabilitation exercise system using marker-less Kinect-based method. The proposed exercise system is developed for the upper limb rehabilitation application that utilizes a low cost depth sensor. In this study, the Kinect skeleton tracking method is used to detect and track the joints of upper limb and then measure the angle of the elbow joint. The users perform the exercise in front of the Kinect sensor and the computer monitor. At the same time, they can see the results that displayed on the screen in real-time. The measurement of elbow joint angles are recorded automatically and has been compared to the reference values for the analysis and validation. These reference values are obtained from the normal range of motion (ROM) of the elbow. The results show the average flexion angle of the elbow joint that achieved by the normal user is 139.1° for the right hand and 139.2° for the left hand. Meanwhile, the average extension angle is 1.72° for the right hand and 2.0° for the left. These measurements are almost similar to the standard range of motion (ROM) reference values. The skeleton tracking works well and able to follow the movement of the upper arm and forearm in real-time.

Flexion And Extension

The elbow joint is key in the functionality of the upper limbs and is used in many activities. In this sense, different pathologies and trauma can affect the Range Of Motion (ROM) and limit the patient’s capabilities such as playing sports, eating, drinking, brushing teeth, among others. Due to the problems described above, we have designed a prototype video game in Python, which is controlled by flexion and extension movements of the elbow. To develop it, we used OpenCV library and Mediapipe framework. The first one oversees image processing that helped us with the registration of the patient's movements in real time by means of the webcam. The final game can be used as a tool to ease the patient rehabilitation exercises.

The human primary motor cortex (M1) undergoes considerable reorganization in response to traumatic upper limb amputation. The representations of the preserved arm muscles expand, invading portions of M1 previously dedicated to the hand, suggesting that former hand neurons are reassigned to the control of remaining proximal upper limb muscles. Hand allograft offers a unique opportunity to study the reversibility of such long-term cortical changes. We used transcranial magnetic stimulation in patient LB, who underwent bilateral hand transplantation 3 years after a traumatic amputation, to longitudinally track both the emergence of intrinsic (from the donor) hand muscles in M1 as well as changes in the representation of stump (upper arm and forearm) muscles. The same muscles were also mapped in patient CD, the first bilateral hand allograft recipient. Newly transplanted intrinsic muscles acquired a cortical representation in LB's M1 at 10 months postgraft for the left hand and at 26 months for the right hand. The appearance of a cortical representation of transplanted hand muscles in M1 coincided with the shrinkage of stump muscle representations for the left but not for the right side. In patient CD, transcranial magnetic stimulation performed at 51 months postgraft revealed a complete set of intrinsic hand-muscle representations for the left but not the right hand. Our findings show that newly transplanted muscles can be recognized and integrated into the patient's motor cortex.

AbstractThe aim of the study was to assess the symmetry of flexion and extension movements in upper limbs in disabled powerlifters during bench press with different barbell loads.29 disabled athletes from the National Powerlifting Team were examined. Mean age was between 23.9 ± 6.1. Mean sport experience was 5.4 ± 3.6 years.Both flexion and extension movement were performed symmetrically, which was indicated by an insignificant (p < 0.05) difference in the movement onset in the left and the right upper limb.Time differences in the movement onset and the achievement of maximal angular velocity were statistically insignificant in all trials (loads from 40% to 95% 1RM). During extension with loads over 60% 1RM differences in time of achieving maximal angular velocity were statistically significant or close.

This study examined the kinematic differences of a bilateral transradial amputee using myoelectric and body-powered prostheses during select activities of daily living. First in harness suspended, body powered then self-suspended externally powered prostheses, the subject's shoulder and elbow joint movements were calculated and compared while completing an elbow range of motion test, simulated drinking from an empty cup, and opening a door. In this case, body-powered prostheses allowed for greater range of elbow flexion but required more shoulder flexion to complete the tasks that required continuous grasp. While using myoelectric prostheses, the user was able to compensate for limited elbow flexion by flexing the shoulder.

Symbrachydactyly is a disruption of embryonic formation and differentiation that leads to a shorter and smaller upper limb with underdeveloped digits such as short or webbed digits, nubbins, or absence of digits. We report a case of a newborn who had symbrachydactyly of multiple digits in the right hand that was not diagnosed during the prenatal period.

Background: The weakness muscle is the biggest impact on patients with stroke, to the practice Range Of Motion with the aim is to maintain or preserve muscle strength, to maintain mobility joints and simulate circulation. With an increase in the incidence of stroke and disability, if the practice Range Of Motion is not implemented it will be a significant decrease in muscle strength, cause muscle kontraktur and a decubitus. Objective: The study aims to find his Range of Motion of muscle strength in patients with stroke in the Puskesmas Bulak Banteng Surabaya. Methods: This study uses Pra-eksperimental One Grup Pra-Post Test Design. Population in this study is a stroke patient who live in the Puskesmas Bulak Banteng Surabaya and sampels 32 of responden. The sample by using techniques simple random sampling. Variables independent in this study is Range Of Motion and the variables dependent is muscle strength. The instrument used in the collection of data is an observation to the strength of muscle and Range of Motion. Result: Wilcoxon test results show the significance level p value = 0.00 with α = 0.05 (p <α) on the right hand while in the left hand shows a significant level p value = 0.00 with α = 0.02 (p<α ).Conclusion:  H0 is rejected that there is influence between ROM exercises gripping the ball against the muscle tone in the right hand and left hand that suffered a stroke.Keywords: Range Of Motion, muscle strength.
