The size, complexity, and cost of gold-standard systems make them not suited to clinical practice, and actually difficult to use outside a dedicated laboratory. Nowadays, ultra-low-cost inertial measurement units are available, but without any packaging or a user-friendly interface. The so-called DYSKIMOT is a home-designed, small-sized, motion sensor based on the latter technology, aiming at being used by clinicians in “real-life situations”. DYSKIMOT was compared with a gold-standard optoelectronic system (Elite). Our goal was to evaluate the DYSKIMOT accuracy in assessing fast head rotations kinematics. Kinematics was simultaneously recorded by systems during the execution of the DidRen Laser test and performed by 15 participants and nine patients. Kinematic variables were computed from the position, speed and acceleration time series. Two-way ANOVA, Passing–Bablok regressions, and dynamic time warping analysis showed good to excellent agreement between Elite and DYSKIMOT, both at the qualitative level of the time series shape and at the quantitative level of peculiar kinematical events’ measured values. In conclusion, DYSKIMOT sensor is as relevant as a gold-standard system to assess kinematical features during fast head rotations in participants and patients, demonstrating its usefulness in both clinical practice and research environments.

Effectiveness of upper-limb robotic-assisted therapy in the early rehabilitation phase after stroke: A single-blind, randomised, controlled trial / Stéphanie Dehem in Annals of physical and rehabilitation medicine, Vol. 62, n°5 (Septembre 2019)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 62, n°5 (Septembre 2019) . - p. 313-320 Titre : Effectiveness of upper-limb robotic-assisted therapy in the early rehabilitation phase after stroke: A single-blind, randomised, controlled trial Type de document : texte imprimé Auteurs : Stéphanie Dehem ; Maxime Gilliaux ; Gaëtan G. Stoquart ; Christine Detrembleur ; Géraldine Jacquemin ; Sara Palumbo ; Anne Frederick ; Thierry Lejeune Année de publication : 2019 Article en page(s) : p. 313-320 Note générale : doi.org/10.1016/j.rehab.2019.04.002 Langues : Anglais (eng) Mots-clés : Stroke  Upper extremity  Robotics  Rehabilitation  Recovery of function Résumé : Background Upper-limb robotic-assisted therapy (RAT) is promising for stroke rehabilitation, particularly in the early phase. When RAT is provided as partial substitution of conventional therapy, it is expected to be at least as effective or might be more effective than conventional therapy. Assessments have usually been restricted to the first 2 domains of the International classification of functioning, disability and health (ICF). Objective This was a pragmatic, multicentric, single-blind, randomized controlled trial to evaluate the effectiveness of upper-limb RAT used as partial substitution to conventional therapy in the early phase of stroke rehabilitation, following the 3 ICF domains. Methods We randomized 45 patients with acute stroke into 2 groups (conventional therapy, n = 22, and RAT, n = 23). Both interventions were dose-matched regarding treatment duration and lasted 9 weeks. The conventional therapy group followed a standard rehabilitation. In the RAT group, 4 sessions of conventional therapy (25%) were substituted by RAT each week. RAT consisted of moving the paretic upper limb along a reference trajectory while the robot provided assistance as needed. A blinded assessor evaluated participants before, just after the intervention and 6 months post-stroke, according to the ICF domains UL motor impairments, activity limitations, and social participation restriction. Results In total, 28 individuals were assessed after the intervention. The following were more improved in the RAT than conventional therapy group at 6 months post-stroke: gross manual dexterity (Box and Block test +7.7 blocks; P = 0.02), upper-limb ability during functional tasks (Wolf Motor Function test +12%; P = 0.02) and patient social participation (Stroke Impact Scale +18%; P = 0.01). Participants’ abilities to perform manual activities and activities of daily living improved similarly in both groups. Conclusion For the same duration of daily rehabilitation, RAT combined with conventional therapy during the early rehabilitation phase after stroke is more effective than conventional therapy alone to improve gross manual dexterity, upper-limb ability during functional tasks and patient social participation.

Head-neck rotational movements using DidRen laser test indicate children and seniors’ lower performance / Renaud Hage  

Public ISBD Titre : Head-neck rotational movements using DidRen laser test indicate children and seniors’ lower performance Type de document : document électronique Auteurs : Renaud Hage ; Fabien Buisseret ; Laurent Pitance ; Christine Detrembleur ; J.-M. Brismée ; Frédéric Dierick Année de publication : 2019 Langues : Anglais (eng) Mots-clés : DidRen test  Neck mobility  Aging Résumé : Sensorimotor control strategies during cervical axial rotation movements have been previously explored in narrow age ranges but never concurrently in Children and Seniors during a well-standardized task. However, the lifespan developmental approach provides a framework for research in human sensorimotor control of the head-neck complex. A cross-sectional design was used to investigate the influence of age on head-neck dynamic performance adopted by asymptomatic Children, Adults and Seniors using a standardized task (DidRen Laser test). Participants performed 5 cycles of left/right headneck complex fast rotational movements toward 3 targets with 30˚ of angular separation. Dynamic performances were computed from total execution time of the test and kinematic variables derived from rotational motion of head measured by an optoelectronic system. Eighty-one participants, aged 8–85 yrs, were stratified in four groups: Children, Younger adults, Older adults and Seniors. Children were significantly slower than Younger (p<0.001) and Older adults (p<0.004) and Seniors slower than Younger adults (p<0.017) to perform the test. Children adopted a lower average speed compared to Younger (p<0.001) and Older adults (p<0.008). Children reached the peaks speed significantly later than Younger (p<0.004) and Older adults (p<0.04) and acceleration significantly later than Younger (p<0.001) and Older adults (p<0.013). From the peak acceleration, Children reached end of the cycle significantly slower than Younger (p<0.008) and Older adults (p<0.008). Children significantly differed from all other groups for rotational kinetic energy, with smaller values compared to Younger adults (p<0.001), Older adults (p<0.005) and Seniors (p<0.012). Variability was also significantly higher for Seniors and Children. In conclusion, age influences head-neck visually elicited rotational dynamics, especially in Children. These results suggest that age should be taken into account when establishing normative data and assessing dynamic head-neck sensorimotor control of patients with neck pain.
