The purpose of this investigation was to evaluate differences in quadriceps corticospinal excitability, spinal‐reflexive strength, and voluntary activation before, 2 weeks post 6 months post‐anterior cruciate ligament reconstruction ( ACLr ). This longitudinal, case‐control examined 20 patients scheduled for (11 females, 9 males; age: 20.9 ± 4.4 years; height:172.4 7.5 cm; weight:76.2 11.8 kg) healthy controls age:21.7 3.7 height: 173.7 9.9 weight: 76.1 19.7 kg). Maximal isometric...
To determine the effect of core muscle strengthening on balance in community-dwelling older adults, 24 healthy men and women between 65 85 years old were randomized to either exercise (EX; n = 12) or control (CON; groups. The group performed a home program thrice weekly for 6 wk. Core (curl-up test), functional reach (FR) Star Excursion Balance Test (SEBT) assessed at baseline follow-up. There no differences baseline. At follow-up, EX exhibited significantly greater improvements curl-up...
Recent studies suggest that the cost of muscle contraction may be reduced in old age, which could an important mediator age-related differences fatigue under some circumstances. We used phosphorus magnetic resonance spectroscopy and electrically elicited contractions to examine energetic ankle dorsiflexion 9 young (Y; 26 +/- 3.8 yr; mean SD) older healthy men (O; 72 4.6). hypothesized energy twitch tetanic would lower O this difference greater during at f(50) (frequency 50% peak force from...
Altered neuromuscular function and decreased dorsiflexion range of motion (DFROM) have been observed in patients with chronic ankle instability (CAI). Joint mobilizations are indicated for restoring DFROM dynamic postural control, yet it remains unknown if a mobilization can alter excitability muscles surrounding the ankle.To determine immediate effects Maitland grade III anterior-to-posterior joint on spinal-reflex corticospinal fibularis longus (FL) soleus (SOL), DFROM,...
Alterations in corticomotor excitability are observed a variety of patient populations, including the musculature surrounding knee and ankle after joint injury. Active motor threshold (AMT) motor-evoked-potential (MEP) amplitudes elicited through transcranial magnetic stimulation (TMS) outcome measures used to assess have been deemed reliable upper-extremity musculature. However, there few studies assessing reliability TMS lower-extremity musculature.To determine intersession AMT MEP over 14...
Abstract Introduction Frailty at listing for lung transplant has been associated with waitlist and post‐transplant mortality. trajectories following transplant, however, have less well characterized, including whether recipient frailty improves. The objective of this study was to identify prevalence risk factors discharge evaluate changes in frail recipients enrolled an outpatient physical therapy program. Methods This a single‐center prospective cohort recipients. Enrollees completed short...
We have developed an optical method for the evaluation of oxygen consumption (Vo(2)) in microscopic volumes spinotrapezius muscle. Using phosphorescence quenching microscopy (PQM) measurement interstitial Po(2), together with rapid pneumatic compression organ, we recorded disappearance curve (ODC) muscle anesthetized rats. A 0.6-mm diameter area tissue, preloaded phosphorescent probe, was excited once a second by 532-nm Q-switched laser pulse duration 15 ns. Each evoked decays analyzed to...
After anterior cruciate ligament (ACL) injury and reconstruction, abnormal biomechanics during daily tasks may have prominent detrimental long-term consequences on knee joint health. The purpose of this study was to longitudinally evaluate hip stair ascent descent in patients with acute ACL at return activity after reconstruction.Twenty individuals unilateral (age, 20.9 ± 4.4 yr; height, 172.4 7.5 cm; mass, 76.2 12.2 kg) that were scheduled undergo surgical reconstruction compared 20 healthy...
Abstract The movement system has been adopted as the key identity for physical therapy profession, and recognition of therapists’ primary expertise in managing dysfunction is an important achievement. However, existing models seem inadequate guiding education, practice, or research. Lack a clear, broadly applicable model may hamper progress therapists actually adopting this identity. We propose composed 4 elements essential to all movement: motion, force, energy, control. Although these...
Abstract In this crossover study, we wished to determine if normalized inter-limb differences in strength differed from voluntary activation at 30°, 70°, and 90° of knee flexion. We also assessed the relationship between torque with activation. Twenty-five healthy volunteers were used for final data analyses; order leg tested, joint angle, measurement technique (isokinetic strength, activation) randomly assigned. Quadriceps was measured isokinetically 1.05 rad · s−1, while quadriceps via...
During ischemia and some types of muscular contractions, oxygen tension (Po(2)) declines to the point that mitochondrial ATP synthesis becomes limited by availability. Although this critical Po(2) has been determined in animal tissue vitro situ, there remains controversy concerning potential disparities between values measured vivo ex vivo. To address issue, we used concurrent heteronuclear magnetic resonance spectroscopy (MRS) determine intracellular resting human skeletal muscle We...
The 4-Element Movement Model (4EMM) has been proposed as framework to guide clinical decision making in the physical therapy management of individuals with movement disorders. model is centered on primary elements movement, including motion, force, control, and energy. Clinical application begins selection a task, followed by systematic observation performance amount, speed, symmetry, symptoms provoked during movement. Testable hypotheses about impairments contributing problems are then...
Abstract Objective Severe coronavirus disease 2019 (COVID-19) can result in irreversible lung damage, with some individuals requiring transplantation. The purpose of this case series is to describe the initial experience rehabilitation and functional outcomes 9 patients receiving a transplant for COVID-19. Methods Nine individuals, ranging age from 37 68 years, received bilateral orthotopic transplantation (BOLT) COVID-19 between December 2020 July 2021. Rehabilitation was provided before...
Abstract Objective The purpose of this case report is to describe the acute rehabilitation an individual with severe COVID-19 complicated by myocarditis, focusing on both facility-wide and patient-specific strategies. Methods A 50-year-old male presented emergency department progressive dyspnea confirmed COVID-19. He developed hypoxic respiratory failure heart requiring prolonged mechanical ventilation. Mobility was limited impairments in strength, endurance, balance, cognition. referral,...
