“…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.…”

“…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].…”

“…She demonstrated increased radial deviation of the wrist, flexion of the elbow, and abduction of the shoulder during functional activities as compared with control subjects, especially with force transmission. Prior studies have demonstrated an asymmetric motion deficit but have not correlated these data with functional activities and examined how it affects the rest of the upper extremity [9].…”

“…To date, motion analysis of the hand and wrist has constrained larger joints or simplified activity to relatively uniplanar or phasic [3,8,9]. Because studies have previously demonstrated alterations in static ROM testing of the thumb in patients with OA [9], our first objective was to determine whether in vivo kinematics of the thumb and hand could be quantified in subjects without arthritis during functional tasks Specifically, we evaluated the effect of carpometacarpal joint loading on upper limb position during three functional tasks: grasp, jar opening, and key pinch. These activities occupy several planes of motion, are nonphasic, and are constrained only by the hand placed on the targeted objects equipped with load cells.…”
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.

“…Electrogoniometric studies with a gimbal coordinate system provide estimates on elbow [76] and wrist [19,84,94] ROM for functional activities. The functional CMC joint range is harder to assess even with constraining experiments [43,55,74], given the discrete but exacting motion of this joint and the functional restriction splints might impart [87].…”

Objective. To synthesize the literature on the efficacy of existing nonsurgical interventions for trapeziometacarpal (TM) osteoarthritis (TMO). Methods. A medical librarian conducted an electronic search in 16 databases. Two authors independently carried out study selection, data extraction, and risk-of-bias assessment. The Agency for Healthcare Research and Quality guidance was followed to integrate a valid body of evidence from the existing systematic reviews. Intervention effects were estimated based on the Cochrane Collaboration review methodology. Results. We identified 17 systematic reviews, 34 randomized controlled trials, and 6 nonrandomized controlled trials. Most of the studies had unclear or high risk of biases. Evidence of low-to-moderate quality supports the superiority of the following interventions for pain and/or physical function: 1) saline over steroid intraarticular injections confirmed by radiography, 2) saline injections over sham (i.e., pressure) in tender subcutaneous areas, 3) custommade thermoplastic thumb orthosis over no intervention or a control, 4) custom-made thermoplastic hand-based TM joint orthosis over no intervention, 5) radial nerve mobilization over sham ultrasound, and 6) a combination of hand exercises and TM joint and median/radial nerve mobilization over sham ultrasound. Conclusion. This comprehensive systematic review allowed collating evidence-based data on the efficacy of nonsurgical interventions for TMO. Steroid intraarticular injections would not be more effective than saline injections. Rehabilitative interventions (orthosis, exercises, nerve mobilization) would be efficacious. However, these findings must be treated with circumspection due to methodologic limitations in many studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
