Force--time characteristics of hip high velocity, low amplitude manipulation in asymptomatic adults: with and without a drop piece.

of HVLA hip manipulation (HVLA-HM) with (DP) and without (NDP) a drop-piece. Methods: Twenty asymptomatic participants (22- 28 years; 60% female) received 3 whip HVLA-HM (DP) on one hip and 3 whip HVLA-HM (NDP) on the other. Force-time characteristics were collected using Force-Sensing Table Technol...

        of HVLA hip manipulation (HVLA-HM) with (DP) and without (NDP) a drop-piece. Methods: Twenty asymptomatic participants (22- 28 years; 60% female) received 3 whip HVLA-HM (DP) on one hip and 3 whip HVLA-HM (NDP) on the other. Force-time characteristics were collected using Force-Sensing Table Technology (FSTT®) and analyzed descriptively. Results: On average, HVLA-HM (DP) had a 1st peak force initiation of 40N (±19), peak force of 637N (±218), time to 1st peak of 62ms (±26), loading rate of 10763N/s (±5042) and 2nd peak force of 197N (±85). HVLA-HM (NDP) had a 1st peak force initiation of 36N (±23), peak force of 567N (±290), time to 1st peak of 63ms (±22), loading rate of 9465N/s (±5966) and 2nd peak force of 197N (±82). Conclusion: Forces during these techniques present with slightly higher peak forces and loading rates during HVLA-HM (DP) at the patient-table interface.
        Objectifs: Décrire les caractéristiques de la force et du temps de la manipulation de la hanche à haute vélocité et à faible amplitude (MH-HVLA) avec (PV) et sans (SPV) planche de vitesse. Méthodes: Vingt participants asymptomatiques (22 à 28 ans; 60 % de femmes) ont reçu trois HVLA-MH en coup de fouet (PV) sur une hanche et trois HVLA-MHen coup de fouet (SPV) sur l'autre. Les caractéristiques de la force et du temps ont été recueillies à l'aide de la technologie des tables détectant la force (FSTT®) et analysées de manière descriptive. Résultats: En moyenne, la HVLA-MH (PV) avait une première force maximale au départ de 40 N (environ 19), une force maximale de 637 N (environ 218), un temps de première force maximale de 62 ms (environ 26), un taux de charge de 10 763 N/s (environ 5042) et une deuxième force maximale de 197 N (environ 85). La HVLA-MH (SPV) avait une première force maximale au départ de 36 N (environ 23), une force maximale de 567 N (environ 290), un temps de première force maximale de 63 ms (environ 22), un taux de charge de 9465 N/s (environ 5966) et une deuxième force maximale de 197 N (environ 82). Conclusion: Les forces lors de ces techniques présentent des forces maximales et des taux de charge légèrement plus élevés pendant la HVLA-MH (DP) dans le contexte d'un patient sur une planche.
