“…These observations were confirmed in recent studies, in which robotic/electromechanical devices enabled practice of independent and repetitive movements, particularly in a motivational context enriched by virtual reality, as in this study (Backus et al, 2010, Mehrholz et al, 2012. Movement smoothness has been used as a measure of motor performance in both healthy subjects and patients affected by stroke (Platz et al, 1994;Kahn et Weight support device for upper limb rehabilitation al. , 2006).…”

SummaryThe aim of this study was to compare the effectiveness in acute stroke patients of a rehabilitation program performed with or without an arm weight support device. Twenty-eight acute, first-ever unilateral stroke patients were enrolled in a single-blind, randomized controlled trial. Clinical evaluation included Fugl-Mayer Assessment, Functional Independence Measure and kinematic analysis [maximum and mean hand velocity, maximum range of motion (Max RoM), normalized jerk (NJ)]. Patients received 12 daily 30-minute sessions (6/week) of additional upper limb therapy performed using an arm weight support device (study group) or additional traditional physiotherapy (control group). The patients were evaluated on admission and at the end of the rehabilitation intervention. The two groups were clinically comparable on admission (p>0.05). Both groups showed significant improvements in clinical scale scores and in Max RoM in flexion-extension, while only the study group showed improvements in NJ and in Max RoM in adductionabduction.Arm weight support training improves functional motor outcome and movement smoothness after stroke Rehabilitation training using an arm weight support device appears to be a useful method to supplement conventional therapy in acute stroke patients, increasing smoothness of movement and motor function.

“…Movement smoothness is often used to assess motor performance in both healthy and disabled subjects (Puniello et al, 2000, Platz et al, 1994, Rohrer et al, 2002, Hreljac, 2000. The meansquared jerk value during the movement has been reported as an index of smoothness with the assumption that minimizing this value is indicative of improved movement control (Platz et al, 1994, Puniello et al, 2000, Hass et al, 2004.…”

“…The meansquared jerk value during the movement has been reported as an index of smoothness with the assumption that minimizing this value is indicative of improved movement control (Platz et al, 1994, Puniello et al, 2000, Hass et al, 2004. The adults transitioning to frailty demonstrated smoothness values of the COP trace during S1 and S2 that were 2 times smaller than those exhibited by the PD group, suggesting better coordination of body movement during these phases of the gait initiation task.…”

“…Movement smoothness has been used as a measure of motor performance of both healthy subjects (Platz et al, 1994) and persons with stroke (Trombly, 1993;Kahn et al, 2001). Smoothness measures have most often been based on minimizing jerk, the third time derivative of position (Flash and Hogan, 1985), although many other measures are possible, including snap, the fourth time derivative of position (Edelman and Flash, 1987), and counting peaks in speed (Brooks et al, 1973;Fetters and Todd, 1987;Cirstea and Levin, 2000;Kahn et al, 2001).…”

Smoothness is characteristic of coordinated human movements, and stroke patients' movements seem to grow more smooth with recovery. We used a robotic therapy device to analyze five different measures of movement smoothness in the hemiparetic arm of 31 patients recovering from stroke. Four of the five metrics showed general increases in smoothness for the entire patient population. However, according to the fifth metric, the movements of patients with recent stroke grew less smooth over the course of therapy. This pattern was reproduced in a computer simulation of recovery based on submovement blending, suggesting that progressive blending of submovements underlies stroke recovery.
