Det finns ett behov av att kunna nyttja ett användarvänligt system för interaktion med kroppsnära sensorer vid undervisning och forskning vid skolan för kemi, bioteknologi och hälsa vid Kungliga Tekniska Högskolan. Ansvariga vid utbildningen har därför gett i uppdrag att utreda om ett specifikt sensorsystem, Movesense, kan utgöra grunden för ett användarvänligt verktyg för att kunna studera biomekaniska rörelser inom utbildning och forskning. En förstudie har genomförts för att undersöka sensorsystemets potential. En systemprototyp har utvecklats för konfiguration av sensorsystemet och hämtnin

Abstract:

<p>Background: The majority of the occupational accidents and work-related diseases at Swedish workplaces occur due to poor ergonomics during lifts and transportation of objects. The most common consequence of poor ergonomic conditions is low back pain (LBP) and the risk of developing LBP increases as the mechanical loading on the intervertebral disks grows. This study has investigated the biomechanical loading in the low back during two different types of patient lifts. The first lift (lift A) is developed by Modern Arbetsteknik (MA) and the second lift (lift B) is a common lifting technique

Det är inte väl studerat hur denna asymmetri påverkar dessa personers stående och gång, och inte heller vilka besvär som detta skulle kunna orsaka. SYFTE: Att undersöka om någon skillnad i stillastående kropps-hållning och gångmönster uppstår då personer med transhumeral amputation använder respektive inte använder protes. Utöver det så är också syftet att undersöka om ryggbesvär förekommer hos personer med denna amputationsnivå. METOD: Två transhumeralt amputerade personer deltog i studien. Statisk undersökning

<p>This thesis investigated the effect of the following constraints: body anthropometrics, gender, maximal isometric strength, type of training program, instruction and ball weight. These constraints were investigated in relation to the coordination and performance (i.e. velocity and accuracy) in overarm throwing of experienced handball players. Instruction emphasising accuracy and/or velocity of throwing performance influenced the maximal ball velocity but showed no effect on accuracy. The difference in ball velocity was a result of the difference in maximal linear velocity of the upper body

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measurin

Abstract:

Injuries in the female gymnast are common and it is important to understand the biomechanical factors responsible for injury. The Back Walkover maneuver requires one of the greatest amounts of lumbar hyperextension compared to other common gymnastic maneuvers. During the Back Walkover large lateral and vertical impact forces follows on the spine. The spine and muscles around the spine have to absorb generally large forces; therefore the loads on the back and certainly on the lower back are of significant interest. Additionally, it takes a lot of strength and a vast range of motion to perform g

Händerna är bland de första drabbade kroppsdelarna, med nedsatt funktion och försämrad livskvalitet hos patienten som följd.

Abstract:

The aorta, the main and largest artery in the human body, is susceptible for many types of problems. One of the most common aortic disease is the formation of an aneurysm. Endovascular aortic aneurysm repair (EVAR) is a minimally invasive treatment option for aortic aneurysms, involving the deployment of an expandable stent graft within the aorta without operating the aneurysm directly. With 1.5 to 43 % of EVAR patients having postoperative complications, research to help predict these complications of EVAR is of essence. In this study, the deformations of the aorta induced by a deployed stent
