Hindlimb unloading alters ligament healing

Journal of Applied Physiology, 2003
We investigated the hypothesis that hindlimb unloading inhibits healing in fibrous connective tissue such as ligament. Male rats were assigned to 3- and 7-wk treatment groups with three subgroups each: sham control, ambulatory healing, and hindlimb-suspended healing. Ambulatory and suspended animals underwent surgical rupture of their medial collateral

Effect of hindlimb unloading on two hindlimb muscles during treadmill locomotion in rats

European Journal of Applied Physiology, 1997
The purpose of the study was to examine the pattern of electromyographic (EMG) activity of the rat soleus (SOL) and tibialis anterior (TA) muscles during treadmill locomotion at various speeds after 7 days of hindlimb unloading (HU). Raw EMG signals were processed to determine cycle duration, burst duration and mean EMG (burst surface divided by its ...

Orthotopic Hindlimb Transplantation in the Mouse

Journal of Reconstructive Microsurgery, 2003
There are many potential advantages to using a mouse as a model for composite tissue transplantation, particularly to examine the mechanisms behind various tolerance induction protocols. The purpose of this study was to evaluate the reliability of a new hindlimb transplant model in the mouse. Fifteen Swiss-Webster mice, 14 to 16 weeks old (35 to 50 g),

Treadmill training for hindlimb transplanted rats

Microsurgery, 2007
AbstractFunctional improvement is an important concern for a composite allograft with motor function. As the procedure of rat composite limb transplantation is a well‐established model, we focused on the effects of rehabilitation using this model. We performed the rat hindlimb transplantation in syngenic combination using a modified method confirming ...

Quiet breathing in hindlimb casted mice

Respiratory Physiology & Neurobiology, 2018
The hindlimb casting model was developed to study skeletal muscle reloading following a period of unloading. It is unknown if ventilation parameters of mice are affected by the casting model. We tested the hypothesis that hindlimb casted mice have similar ventilatory patterns compared to mice with the casts removed.

Hindlimb unloading: rodent analog for microgravity

Journal of Applied Physiology, 2016
The rodent hindlimb unloading (HU) model was developed in the 1980s to make it possible to study mechanisms, responses, and treatments for the adverse consequences of spaceflight. Decades before development of the HU model, weightlessness was predicted to yield deficits in the principal tissues responsible for structure and movement on Earth, primarily

Adrenergic mechanisms in canine hindlimb circulation

Cardiovascular Research, 1974
Epinephrine dilates or constricts canine hindlimb vasculature depending upon the dose; however, norepinephrine causes only vasoconstriction. Since both agonists interact with alpha and beta adrenergic receptors, one might expect norepinephrine to cause vasodilation under appropriate circumstances.

Hindlimb unloading rodent model: technical aspects

Journal of Applied Physiology, 2002
Since its inception at the National Aeronautics and Space Administration (NASA) Ames Research Center in the mid-1970s, many laboratories around the world have used the rat hindlimb unloading model to simulate weightlessness and to study various aspects of musculoskeletal loading.

Kinematic analysis of cat hindlimb stepping

Journal of Neurophysiology, 1995
1. The purpose of this study is to analyze the kinematics of stepping from the point of view of limb control by attempting to dissociate the various neuronal and mechanical factors that shape actual movements observed experimentally. The cat hindlimb, like the primate arm, is a multijointed mechanical system with redundant degrees of freedom.

Congenital hindlimb rigidity in a dog

Journal of Small Animal Practice, 1977
ABSTRACTMuscle biopsies and electromyography were used in the study of a congenital muscle disorder in a dog with hyperextension of one hind limb.
