Training errors are often implicated in the development of running-related injuries (RRIs), yet little is known about "how much is too much" when it comes to progression of training loads. Biomechanical factors are also believed to moderate RRI risk since the magnitude and distribution of forces dep...

Duchenne muscular dystrophy (DMD) is a genetic disease characterized by muscle degeneration and fibrosis, often leading to respiratory failure. Diaphragm sections from mdx and healthy mice were biaxially tested to determine passive properties before and after enzymatic collagen digestion. We found t...

Strain is an important mechanical stimulus for adaptation of¶ biological tissues such as tendons. Triathletes frequently¶ suffer from chronic tendon injuries [1], but investigations on¶ tissue strain are lacking for this population. We investigated¶ triceps surae tendon strain in triathletes dur...

A methodology is outlined for conducting a subject-specific analysis for a low speed rear-end collision. To demonstrate, a MADYMO model was built from 3D laser scan data of the subject driver and vehicle interior, then given motion consistent with imaging of the subject vehicle’s Event Data Record...

Low back pain is a disabling pathology to which several workers are exposed. Our study aimed at finding biomechanics driven biomarkers of incorrect lifting postures. For this reason two cohort of subjects were analysed (healthy and affected by low back pain) through plantar pressure, electromyograph...

The number of head injuries in soccer increases every year, but only few studies have been carried out directly on the field. The restricted data limit the understanding of the risk of head injuries. Thus, the purpose of this research project was to identify head kinematics of specific head impacts ...

This study examines the biomechanical and patient reported outcomes for patients using an Intrepid Dynamic Exoskeletal Orthosis (IDEO) whom are one year post rehabilitation. It is unknown how well these devices are being used and how these patients feel they are doing compared to other patients who ...

Tensile properties of native and acellular human dura mater are of increasing interest for transplant surgery. The biomechanical properties of 18 cadaver-matched pairs of acellular and native human dura mater samples were investigated here. An individually-established osmotic stress protocol and the...

There is a wide correlation between the biomechanical studies (baropodometry) carried out in the Laboratory of Biomechatronics at CIATEC, A.C., and pelvic limb shortening identified with radiographic scans or radiometry studies.

Posterior tibialis tendon dysfunction (PTTD) is the principal cause of adult acquired flatfoot. As PTTD is related to the eversion of the rear foot, it is important to know if foot orthoses can attenuate this movement during gait. Results of this study show that custom foot orthoses (FOs) reduced ev...

Each of these blog ideas targets a real question or problem your customers might search for on a busy Tuesday afternoon. By addressing topics like "how to" tasks, troubleshooting fixes, and optimization tips, you can create helpful content that both supports current Dryfta users and attracts new one...

Wearable sensors enable collection of large quantities of data from real-world movement, but the variety of behaviors recorded makes it challenging to distill generalizable knowledge from these data. This research develops a method for comparing the effects of mobility interventions on frequently-re...

Patellofemoral joint stress (PFJS) was used to quantitatively assess the biomechanic characteristics of the patellofemoral joint of older adults when descending the stairs. Compared with young adults, older adults had lower knee moment in the sagittal plane, quadriceps strength, and PFJS, which may ...

Spotting is a dance-specific head coordination in which dancers fixate their heads to the front while turning. An experimental study in which dancers performed continuous revolutions aimed to analyze parameters of the spotting technique, balance, and dizziness. To this end, motion capture and EOG me...

Anterior cervical discectomy fusion has a complication in which failure and subsidence of the allograft spacer occurs. In this study, the failure and subsidence risk stresses on allograft spacer were quantitatively analyzed using 6 different post-op models of ACDF with allograft spacer coupled with ...

To investigate lower limb movement differences on Warrior I pose between professional and novice for the best performance motion in Yoga. Five professional female Yoga instructors and five novice female were selected as subjects. The force plates and motion capture system were used to acquire the ki...

Several fundamental differences in shooting posture and biomechanics were identified between expert and novice marksmen. The findings provide a foundation to begin modifying training interventions which may help accelerate performance optimization for marksmen.

The arm of this study was to understand the differences in biomechanical characteristics between running one and two-legged vertical jumps. 10 male college volleyball players performed one and two-legged vertical jumps randomly. Kinematic and kinetic data were collected by using Six infra-red Qualis...

According to the World Health Organization, the North American population has the highest incidence of hip joint osteoarthritis (OA). Gait limitations are commonly observed in the context of hip OA. This study aimed at assessing the effect of an intra-articular (IA) injection of hyaluronic acid (HA)...

Despite there are many types of internal fixation devices for surgical treatment of acetabular fractures, reliable and accurate test method for assessing post-op biomechanical stability is still lacking. This makes more difficult for surgeons to accurately predict post-op stability of the device to ...

The vocal fold lamina propria plays an important role in human voice production and control. The lamina propria is often divided into the superficial, intermediate, and deep layers, with each layer of distinct mechanical properties. This layer-wise distinction in mechanical properties is generally c...

The purpose of this study was to clarify the BLD of spring-like behaviour in hopping at various frequencies and the effect of chronic adaptation via sprint running experience on BLD during the hopping. Fifteen male experienced sprinters and 12 male novices participated in this study. Participants we...

There exists no clear guidance for the biomechanical accommodation period to a prosthetic device for persons with lower limb loss. As such, studies have utilized accommodation periods ranging from 5 minutes to >1 year before commencing data collection [1], potentially limiting reliability and validi...

Pelvic fracture is a disruption of the bony structures of the pelvis. Pelvic fracture fixations are needed to restore the original position. The present study investigated the strengths and limitations of different treatment strategies for vertically unstable pelvic fractures using a three-dimension...

Three-point jump shot is a necessary skill for basketball players. However, the injuries often occur while landing. This injury may be caused by an accident while competing or practicing sports.

A causal relationship between pain and gait alterations in knee osteoarthritis (OA) is often implied in the cross sectional studies, however evidence of a casual relationship between pain and gait mechanics in the literature is limited. We have explored the motor system response to acute exacerbatio...

This is a pilot study to investigate if a new conceptual diagnostic test, the Stand-Up Test (SUT) can assess subtle mobility decline in independent community dwellers. A 3D motion capture analysis was applied to quantify the center of mass momentum (COM) during sit-to-stand tasks. The COM controls i...
