“…Kinematic studies have been made of the upper limb in which reaching/grasping movements on a horizontal plane as a free movement without arm support [ 8 ] and with arm support [ 9 - 11 ] have been analyzed. However, the analysis of purpose-oriented movements must be proposed because the musculoskeletal system has potentially a larger number of ways to achieve the motor task, permitting the organism to adapt to different environmental conditions.…”

BackgroundThree-dimensional kinematic analysis equipment is a valuable instrument for studying the execution of movement during functional activities of the upper limbs. The aim of this study was to analyze the kinematic differences in the execution of a daily activity such as drinking from a glass between two groups of patients with tetraplegia and a control group.MethodsA total of 24 people were separated into three groups for analysis: 8 subjects with metameric level C6 tetraplegia, 8 subjects with metameric level C7 tetraplegia and 8 control subjects (CG). A set of active markers that emit infrared light were positioned on the upper limb. Two scanning units were used to record the sessions. The activity of drinking from a glass was broken down into a series of clearly identifiable phases to facilitate analysis. Movement times, velocities, and the joint angles of the shoulder, elbow and wrist in the three spatial planes were the variables analyzed.ResultsThe most relevant differences between the three groups were in the wrist. Wrist palmar flexion during the back transport phase was greater in the patients with C6 and C7 tetraplegia than in the CG, whereas the highest wrist dorsal flexion values were in forward transport in the subjects with C6 or C7 tetraplegia, who required complete activation of the tenodesis effect to complete grasping.ConclusionsA detailed description was made of the three-dimensional kinematic analysis of the task of drinking from a glass in healthy subjects and in two groups of patients with tetraplegia. This was a useful application of kinematic analysis of upper limb movement in a clinical setting. Better knowledge of the execution of this movement in each of these groups allows therapeutic recommendations to be specifically adapted to the functional deficit present. This information can be useful in designing wearable robots to compensate the performance of AVD, such as drinking, in people with cervical SCI.

“…In order to analyze the upper limb movement it is necessary to define and to develop the biomechanical model based on the activity to be analyzed. Kinematic studies have considered upper limb in which reaching/grasping movements on a horizontal plane as a free movement without arm support (van Anden et al 2008) and with arm support (McCrea et al 2002;Dwan and McIntosh 2006) have been analyzed. However, the analysis of purpose-oriented movements must be proposed because the musculoskeletal system has potentially a larger number of ways to achieve the motor task, permitting the organism to adapt to different environmental conditions.…”

“…It has been confirmed that movement characteristics can vary depending on the objective to be completed. For example, upper limb kinematics is not the same in pointing to an object as when a grasping function is added (Dwan and McIntosh 2006;Safaee-Rad et al 1990). Several studies have been published recently on the three-dimensional analysis of ADLs in healthy subjects (Murphy et al 2006;van Anden et al 2008;Petuskey et al 2007).…”

“…Following the recommendations of earlier studies, the body segments were defined by placing 8 markers on the superficial bony prominences of the right upper limb, which were easily positioned in the different analyses (Cirstea and Levin 2000;Michaelsen et al 2001;Murphy et al 2006;Dwan and McIntosh 2006). These markers were placed on the head of the third metacarpal, radial and ulnar styloid processes of the wrist, lateral and medial epicondyles of the elbow, right and left acromion and right iliac crest.…”
