“…Angles at different time intervals are collected during experiments by video motion capture system for 10 repeated cycles and based on average data, trajectories for each case is plotted ( Figure 5,6, 7). Equations of trajectories are obtained by using curve fitting technique and are found that all trajectories follow a third order polynomial as below: θ = C 0 +C 1 t +C 2 t 2 +C 3 t 3 (6) In the above equation θ is the variation of angle with time and the values of constants are illustrated in Table III. Based on trajectory equation velocity and acceleration are calculated for particular time between initial and final time.…”

The paper deals with the dynamic analysis of human arm, determination of shoulder and elbow torques considering isotonic and isokinetic exercise activities. Using Lagrangian-Euler method for dynamic equation of motions, code in MATLAB are developed which can be used to give torques encountered at shoulder and elbow joints for the respective trajectories obtained for different cases. Video tracking and motion capture techniques are used and clippings are analysed using NexGen Ergomaster tool. The results obtained for isokinetic flexion are in tune with those obtained by other researcher.

“…Many analyses are carried out for the different activities of human arm. R.Ramanathan et al [6] analyzed the arm trajectories for everyday tasks for the development of an upper limb orthosis. Investigation of arm motion between fixed boundary conditions within a two dimensional space was done by A.Ailon et al [7].…”

“…Table 1 reports the selected tasks, gathered in four priority groups according to their importance. Their ranking was established by the authors considering the indications from both the specialized literature [1,14,17,20] and the therapists' and amputees' impressions retrieved at the INAIL Prostheses Centre. The RTs were determined by means of an experimental session of motion analysis.…”

The application of a design methodology for the determination of the optimal prosthesis architecture for a given upper limb amputee is presented in this paper along with the discussion of its results. In particular, a novel procedure was used to provide the main guidelines for the design of an actuated shoulder articulation for externally powered prostheses. The topology and the geometry of the new articulation were determined as the optimal compromise between wearability (for the ease of use and the patient's comfort) and functionality of the device (in terms of mobility, velocity, payload, etc.). This choice was based on kinematic and kinetostatic analyses of different upper limb prosthesis models and on purpose-built indices that were set up to evaluate the models from different viewpoints. Only 12 of the 31 simulated prostheses proved a sufficient level of functionality: among these, the optimal solution was an articulation having two actuated revolute joints with orthogonal axes for the elevation of the upper arm in any vertical plane and a frictional joint for the passive adjustment of the humeral intra-extra rotation. A prototype of the mechanism is at the clinical test stage.

“…There are a numerous quantity of analysis techniques for upper limb movements, which can be classified in two paradigms: one approach is based on markers and video-cameras [4,5,2,6]. Other approaches are based on wearable sensors, such as magnetometers and inertial sensors [7,8,9,10].…”

Abstract-Feeding and drinking are Activities of Daily Living which can be used to assess the motor control and functional ability of the upper limb. This paper presents the upperlimb kinematics during the execution of feeding and drinking activities, such analysis consisted in the measurement of angles of flexion for trunk and arm. Eight healthy subjects performed these activities in a simulated-environment while they were video recorded. Markers on anatomical landmarks were used to analyze the kinematics of the upper limb in the sagittal plane. Additionally an electro-hydraulic sensor was attached to each upper limb to assess the vertical position of the wrist relative to the shoulder. Results showed a difference on the angles of the elbow and trunk. The electro-hydraulic sensor showed to be an efficient way to record the vertical position of wrist.
