The First Step Toward The Future Of Wearables In Rehabilitation, Morgan L. Andrews

Tibial stress fractures are a major problem for runners and military athletes due to the high-intensity nature of their training. This injury is commonly treated through subjective measures including rest and management of symptoms that are evaluated by a therapist or trainer. With the advancement of technology such as inertial measurement units with accelerometers, clinicians may have the potential to provide an objective way to rehabilitate tibial stress fractures. Wearable technology is becoming more popular to be used in training but has not made it to rehabilitation yet. This study examines the validity of derived measures from the IMeasureU IMU …

The primary purpose was to determine if there is a difference between the median frequency slopes of 5 posterior shoulder muscles during the initial portion of the Posterior Shoulder Endurance Test (PSET) at the 90° and 135° shoulder abduction positions. Fifty-five healthy volunteers (31 females) participated. The median frequency of the posterior deltoid (PD), upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), and infraspinatus (INF) was measured during the PSET at 90° and 135° of shoulder abduction. External torque of 13 ± 1 Nm was used for females and 21 ± 1 Nm for males. A fixed effect multi-variable …

Muscle fiber type shifts in respect to satellite cells, muscle stem cells, are not well understood currently. The Peterson Lab has generated a mouse model (PAX7-DTA) that ablates satellite cells to determine if these muscle stem cells contribute to mouse muscle fiber type changes over an eight week period. In the study, control and satellite-cell-ablated mouse groups were split into control and overload groups (via synergist ablation surgery) and placed under similar environmental conditions. Eight weeks post-experiment, muscles were dissected to obtain the plantaris muscles of animals from all groups. Muscle cross-sections obtained were immunohistochemically stained, imaged, quantified by fiber …
