Requirements for upper extremity motions during activities of daily living

After placement of a reverse shoulder endoprosthesis, range of motion is usually still compromised. To what extent this occurs from limitation in motion of the reverse endoprosthesis is, however, unclear. We measured the motion pattern of 16 patients (18 shoulders) during three active and passive range of motion tasks using a six degree-of-freedom electromagnetic tracking device. Despite rotator cuff deficiencies, glenohumeral elevation contributed roughly two-thirds of the total thoracohumeral elevation, which is comparable to healthy subjects. However, patients could not actively use the full range of motion provided by the prosthesis. Although we found considerable interindividual differences in shoulder kinematics, the limitation in glenohumeral range of motion appears related to a lack of generated muscle force and not the design of the prosthesis.

“…During the last 10 years, several kinematic studies have focused on ADL involving an upper extremity (Aizawa et al, 2010;Butler et al, 2010;de los Reyes-Guzmán et al, 2010;Magermans et al, 2005;Murphy et al, 2006;Namdari et al, 2012;Petuskey et al, 2007). Kinematic data for upper extremities can be collected using studies of various tasks considered representative of ADL.…”

“…During the last fifteen years, many kinematic studies have been performed in laboratory settings with the aim of quantifying the upper extremity movements during complete ADL in healthy people (Aizawa et al, 2010;Magermans et al, 2005;Murgia et al, 2010;Murphy et al, 2006;Namdari et al, 2012;Petuskey et al, 2007;Van Andel et al, 2008) and people who have suffered stroke (Kim et al, 2014;Lang et al, 2006;Murphy et al, 2011Murphy et al, , 2013Osu et al, 2011), CP (Butler et al, 2010;Klotz et al, 2013) or SCI (de los Reyes-Guzmán et al, 2010). An important component of a rehabilitation treatment is a quantified assessment that is sensitive to the outcome of interest.…”

Background: Quantitative measures of human movement quality are important for discriminating healthy and pathological conditions and for expressing the outcomes and clinically important changes in subjects' functional state. However the most frequently used instruments for the upper extremity functional assessment are clinical scales, that previously have been standardized and validated, but have a high subjective component depending on the observer who scores the test. But they are not enough to assess motor strategies used during movements, and their use in combination with other more objective measures is necessary. The objective of the present review is to provide an overview on objective metrics found in literature with the aim of quantifying the upper extremity performance during functional tasks, regardless of the equipment or system used for registering kinematic data. Methods: A search in Medline, Google Scholar and IEEE Xplore databases was performed following a combination of a series of keywords. The full scientific papers that fulfilled the inclusion criteria were included in the review. Findings: A set of kinematic metrics was found in literature in relation to joint displacements, analysis of hand trajectories and velocity profiles. These metrics were classified into different categories according to the movement characteristic that was being measured. Interpretation: These kinematic metrics provide the starting point for a proposed objective metrics for the functional assessment of the upper extremity in people with movement disorders as a consequence of neurological injuries. Potential areas of future and further research are presented in the Discussion section.

“…The 2 prosthetic components were placed in about 60° of relative glenohumeral abduction, corresponding to approximately 90° of humeral abduction relative to the torso. 22 In this position, when both components are in neutral version, the back surface of the components are parallel ( Figure 2a). This position was chosen because the coverage of the articular contact surfaces is greatest in this configuration, so that the greatest stability ratio was expected.…”
