Effects Of Neuromuscular Interventions Utilizing External Biofeedback Apparatuses On The Risk And Incidence Of Second Anterior Cruciate Ligament Injuries: A Systematic Review., Marisa Olmo, Rebecca Sharp

DPT Capstones

STUDY DESIGN: Systematic review.

BACKGROUND: Anterior cruciate ligament (ACL) injury is a common orthopedic condition with an estimated rate of 20,000 to 600,000 injuries in the US per year, with higher incidences in athletic and female populations. The rate of re-injury following surgical ACL repair (ACLR)ranges between 13.8-33.3%. Current clinical practice guidelines for ACLR rehabilitation cite inconclusive evidence for definitive outcome measures that accurately determine successful return to sport (RTS). There is a need to establish more effective avenues of rehabilitation interventions to decrease the rate of reinjury, particularly in female athletes. Recent evidence suggests interventions utilizing external biofeedback apparatuses …

Co-Contraction Of Ankle Muscle Activity During Quiet Standing In Individuals With Incomplete Spinal Cord Injury Is Associated With Postural Instability, Kai Lon Fok, Jae W Lee, Janelle Unger, Katherine Chan, Kristin E Musselman, Kei Masani Oct 2021

Co-Contraction Of Ankle Muscle Activity During Quiet Standing In Individuals With Incomplete Spinal Cord Injury Is Associated With Postural Instability, Kai Lon Fok, Jae W Lee, Janelle Unger, Katherine Chan, Kristin E Musselman, Kei Masani

Physical Therapy Publications

Previous findings indicate that co-contractions of plantarflexors and dorsiflexors during quiet standing increase the ankle mechanical joint stiffness, resulting in increased postural sway. Balance impairments in individuals with incomplete spinal cord injury (iSCI) may be due to co-contractions like in other individuals with reduced balance ability. Here we investigated the effect of co-contraction between plantar- and dorsiflexors on postural balance in individuals with iSCI (iSCI-group) and able-bodied individuals (AB-group). Thirteen able-bodied individuals and 13 individuals with iSCI were asked to perform quiet standing with their eyes open (EO) and eyes closed (EC). Kinetics and electromyograms from the tibialis anterior (TA), …

Chronic critical illness is a global clinical issue affecting millions of sepsis survivors annually. Survivors report chronic skeletal muscle weakness and development of new functional limitations that persist for years. To delineate mechanisms of sepsis-induced chronic weakness, we first surpassed a critical barrier by establishing a murine model of sepsis with ICU-like interventions that allows for the study of survivors. We show that sepsis survivors have profound weakness for at least 1 month, even after recovery of muscle mass. Abnormal mitochondrial ultrastructure, impaired respiration and electron transport chain activities, and persistent protein oxidative damage were evident in the muscle of …

Physical Therapy Publications

Continuous theta burst stimulation (cTBS) is a form of noninvasive repetitive brain stimulation that, when delivered over the contralesional hemisphere, can influence the excitability of the ipsilesional hemisphere in individuals with stroke. cTBS applied prior to skilled motor practice interventions may augment motor learning; however, there is a high degree of variability in individual response to this intervention. The main objective of the present study was to assess white matter biomarkers of response to cTBS paired with skilled motor practice in individuals with chronic stroke. We tested the effects of stimulation of the contralesional hemisphere at the site of the …

PURPOSE: The purposes of this study were to document longitudinal developmental trajectories in 6-minute walk test (6MWT) distances and to develop age-specific reference percentiles for children across different Gross Motor Function Classification System (GMFCS) levels.

METHODS: A TOTAL OF: 456 children with cerebral palsy ages 3 to 12 years of, GMFCS levels I to III participated. Children's motor function was classified on the GMFCS, and children completed the 6MWT 2 to 5 times in 2 years.

RESULTS: Longitudinal developmental trajectories support that 6MWT distances increase with age followed by a tapering, as children approach their functional limit relative to their …
