Collapse Button Quick Abstract
Joint range of motion (ROM) is commonly measured using goniometry, which is well established with accepted reference values from the American Academy of Orthopedic Surgeons (AAOS) (Greene & Heckman, 1994). The procedures of obtaining these measures are based on unidirectional and uniplanar passive testing of isolated joint motions in supine, prone or seated positions. The relationships of such ROM measures have been found to have a variable relationship to performance (Craib et al., 1996; Menz, Morris, & Lord, 2006). Utilizing tests of the full kinematic chain from an upright standing position that involve the concurrent use of multiple joints, directions and planes of motion might be one solution to the shortcomings of the traditional ROM testing procedures. Full kinematic chain tests have the advantage of greater specificity to most human movements including, for example, athletic performance. The Star Excursion Balance Test (SEBT) is a widely accepted (Gribble, Hertel, & Plisky, 2012) test of balance and mobility in lower-body joints. While it does not challenge all joint movements at and above the hip (Delahunt et al., 2013), its does offer a platform from which a whole-body mobility test can be created. In the current study we propose a Hand Reach Star Excursion Balance Test (HSEBT), which combines a systematic use of unilateral and bilateral hand reaches, thus also challenging mobility in hip and upper body joints. The purposes of this study were to (1) evaluate in which joints significant motions are elicited by the HSEBT in healthy reference group; and (2) compared to joint movements of the foot, knee, hip and trunk triggered by the HSEBT to normative ROM values.

Collapse Button Quick Abstract
This study investigated if a systematic combination of upright standing reach tests may be used as a test battery for the assessment of joint mobility and identified potential challenges. In addition, it was assessed if selected conventional tests of mobility are correlated with performance in the reach tests. Eight male volunteers executed a series of 20 reach tasks. Their movements were recorded with a 14-camera motion tracking system using a whole-body marker set. Joint ranges of motion were also determined in 4 conventional mobility tests. In all reach tests significant correlations were found between the reach distance and a specific set of joint angles as well as with anthropometric measures. Joint range of motion, as determined in the conventional tests, correlated with reach performance only in 7 of 22 analyzed comparisons. These results suggest that reach tests may offer an approach to test joint mobility in situations closer to “real-life”, however, scaling of anthropometric properties, stability, and balance issues have to be considered.

Collapse Button Quick Abstract
After total knee arthroplasty (TKA) patients often ask when they can resume car driving. This question was the aim of some studies in the past, however no study was found on the possible effects of different surgery techniques on brake response time (BRT). A randomized controlled trial on the effects of two surgery techniques (minimally invasive vs. standard approach) on BRT was designed. In this paper the motor performance of two female patients was compared. Surgery had different effects on the mean BRT of both Patients. The mean BRT of the MIS Patient wasn’t increased 7 days after surgery, while the BRT of the Patient undergoing standard surgery was increased by 46.8% at the same time.

Collapse Button Quick Abstract
After total knee arthroplasty (TKA) patients often ask when they can resume car driving. This question was the aim of some studies in the past, however it is not clear whether minimally invasive surgery (MIS) for total knee replacement has benefits in terms of faster recovering times. With the present study protocol the effects of two surgery techniques for TKA (MIS vs. standard approach) on motor performance parameters will be tested during the performance of an emergency brake in a car simulator. The brake response time components and the muscle activation thresholds of four muscles involved in the task will be the outcomes of the study.
