“…Hand reaches beyond arm's length from standing elicit a dual role of the trunk and lower extremities in both postural stability and joint movements in transferring the hand to the target, linking posture and movement coordination [9][10][11]. As reach distance increases, the trunk, upper and lower extremities work together as one functional unit to move the body toward the target [9] with a greater movement of center of the mass (COM) [9,11] and increased joint movements [12].…”

Abstract:Measuring dynamic postural control and mobility using task-based full-body movements has been advocated. The star excursion balance test (SEBT) is well-established, but it does not elicit large upper body joint movements. Therefore, the hand reach star excursion balance test (HSEBT) was developed. The purpose of the current study was to assess the inter-rater and test-retest reliability and validity of the HSEBT. Twenty-nine healthy male subjects performed ten HSEBT reaches on each leg on four different occasions, led by three different raters. Reach distances were recorded in centimeters and degrees. Then, twenty-eight different healthy males performed the HSEBT while using a standard motion capture system. Reliability was assessed using the intraclass correlation coefficient (ICC) (range 0.77-0.98). Stability of measurement was assessed using the standard error of measurement (SEM) (range 0.3-2.8 cm and 1.7 • -2.6 • ) and coefficient of variation (CV) (range 2.1-14.6%). Change scores were obtained using minimal detectable change (MDC 95 ) (range 0.9-7.9 cm and 4.7 • -7.2 • ). Observed (Max m ) and calculated (Max kin ) maximum hand reach measurements showed good to excellent correlations. Bland Altman analysis established a fixed bias for all tests, which can be partially explained by the kinematic calculations. In conclusion, the HSEBT is a valid and reliable full-body clinical tool for measuring dynamic postural control and functional joint mobility.

“…As reach distance increases, the trunk, upper and lower extremities work together as one functional unit to move the body toward the target [9] with a greater movement of center of the mass (COM) [9,11] and increased joint movements [12]. In addition, different reach directions describe different limits of stability [13].…”

“…Lafond et al, [39] explained that biomechanical inverse dynamics to the activation of the ankle plantar dorsiflexors motor control. This was in agreement with Andersen et al, [40] who declared that patients may have weakness of the extensors and flexors at the ankle and of knee flexors with preservation of strength of the knee extensors and of muscles at the wrist and elbow.…”

“…Movement variability of the constituent parts to some extent can cancel each other out so that an overall control parameter moves with reduced variability [21]. This co-variation or compensatory variability [26] during whole body movement has been demonstrated in a number of studies involving healthy subjects [25,[27][28]. Inter-limb coordination as part of a complex system is controlled dynamically to create the desired movement patterns [24].…”

“…In our interpretation all limbs and the trunk would be key actors in such a complex system of motor control to constrain CoM frontal plane movement; therefore presumably knee activity of the stance leg is part of such a complex system. It has been suggested that movement of all components in the system to constrain CoM movement [25] is achieved through a whole body synergy whereby movement of all constituent parts are related to each other. Movement variability of the constituent parts to some extent can cancel each other out so that an overall control parameter moves with reduced variability [21].…”
