“…We have demonstrated that our protocol reproducibly examines motion of both the small and large joints of the upper extremity in combination. Prior studies, including our own, have demonstrated the ability to accurately perform motion analysis on the larger joints of the upper extremity with good intertrial reliability [3,19,23], whereas others have validated performing motion analysis on the hand alone [9,18,22]. In this study, we were able to appropriately address our primary aim by demonstrating that motion analysis of the entire hand and upper extremity may be performed concurrently and that we can reproducibly perform motion analysis during functional activities.…”

Background Abnormal biomechanical loading has been identified as an associated risk factor of osteoarthritis in the wrist and hand. Empirical data to date are insufficient to describe the role of altered biomechanics in thumb carpometacarpal (CMC) arthritis. Questions/purposes This is a pilot study to evaluate motion analysis of the upper extremity while performing functional tasks. We wished to describe the in vivo kinematics of the thumb and hand in relation to the larger joints of the upper extremity in subjects without arthritis in functional positions at rest and while loading the CMC joint. If reproducible, we then planned to compare kinematics between these subjects and a subject with advanced thumb CMC arthritis.

“…Prior studies have examined static ROM of the digits; however, they do not examine motion during functional activities [9,18,22]. Through our motion analysis, we have demonstrated that even healthy subjects tend to use flexion synergy to increase force generated similar to hemiparetic patients [6].…”

“…The proposed model is an extension to models previously published by Rash et al [11] where focus is on the analysis of flexion/extension of an individual finger only, and Small et al [6] who proposed a model based solely on wrist movements. A similar marker placement method proposed by Carpinella et al [5] uses only 17 markers but does not provide a method of measuring the wrist angles, metacarpal arch and DIP joints of the fingers as presented in this paper.…”

“…Various models have been developed which attempt to characterize all the complex movements of the hand [3]- [7], whereas others are only concerned with specific aspects such as joint rotations or wrist angles [8]- [11]. The work of Degeorges et al [10] is concerned with only modeling 3-D rotations of the index finger joints.…”

Abstract-A kinematic model is presented based on surface marker placement generating wrist, metacarpal arch, fingers and thumb movements. Standard calculations are used throughout the model and then applied to the specified marker placement. A static trial involving eight unimpaired participants was carried out to assess inter-rater reliability. The standard deviations across the data were comparable to manual goniometers. In addition, a test-retest trial of ten unimpaired participants is also reported to illustrate the variability of movement at the wrist joint, metacarpal arch, and index finger as an example of model output when repeating the same task many times.

“…A trend developed recently in biomechanical research is to apply the principles established by the analysis of gait to the upper limb [6][7][8][9][10][11]. The motivation for using three-dimensional kinematic data originated from a desire to understand the biomechanical movements involved in prehensile tasks [12] and has evolved into developing an assessment for rehabilitation [4,13]. Understanding the variability associated with a particular movement in unimpaired participants brings greater understanding of the limitations and compensatory mechanisms involved in comparable movements by impaired participants.…”

The primary objective of the experiments was to investigate the wrist motion of a person while they were carrying out a prehensile task from a clinical hand function test. A sixcamera movement system was used to observe the wrist motion of 10 participants. A very light sphere and a heavy sphere were used in the experiments to study any mass effects. While seated at a table, a participant moved a sphere over a small obstacle using their dominant hand. The participants were observed to move their wrist at a constant angular velocity. This phenomenon has not been reported previously. Theoretically, the muscles of the wrist provide an impulse of force at the start of the rotation while the forearm maintains a constant vertical force on a sphere. Light-heavy mean differences for the velocities, absolute velocities, angles and times taken showed no significant differences (p ¼ 0.05).
