Frontiers in Cellular Neuroscience, 2023 Peripheral nerve injury often results in poor functional recovery due to a prolonged period of muscle denervation. In particular, absent axonal contact, denervated muscle can undergo irrevocable atrophy and diminished receptiveness for reinnervation over

Denervation in hemiplegic muscles. [PDF]
Stroke, 1990 This study examined the frequency of denervation activity in hemiplegic muscles in relation to the size and location of the central lesion. We studied 20 patients, 14 with major unilateral cerebral infarctions in the middle cerebral or internal carotid territories; four with a single lacune in the pons, internal capsule, or thalamus; and two with ...

Targeted Muscle Reinnervation for Intuitive Prosthetic Control
Muscle &Nerve, EarlyView.ABSTRACT The convergence of medical and technological advances has led to a substantial expansion of therapeutic approaches for patients with limb amputations. Targeted muscle reinnervation (TMR) is one of the strategies to improve control of bionic arms and has been applied for more than two decades. Through surgical rewiring of the nerves responsible

Muscle &Nerve, EarlyView.ABSTRACT Introduction/Aims Routine assessment of muscle reinnervation primarily relies on clinical and electromyographic evaluation. The aim of this preliminary study was to evaluate sensitivity of quantitative ultrasound analysis for monitoring intrinsic hand muscle recovery following anterior interosseous nerve (AIN)‐to‐ulnar motor branch ...

EJNMMI ResearchBackground The increased expression of the nicotinic acetylcholine receptor (nAChR) in muscle denervation is thought to be associated with electrophysiological acetylcholine supersensitivity after nerve injury.

Skeletal Muscle, 2017 Background Motor neurons control muscle contraction by initiating action potentials in muscle. Denervation of muscle from motor neurons leads to muscle atrophy, which is linked to mitochondrial dysfunction.

Otolaryngology–Head and Neck Surgery, EarlyView.Abstract Objective Injection laryngoplasty is a standard‐of‐care intervention for unilateral vocal fold paralysis (UVFP), offering minimally invasive medialization with limited durability. We evaluated a regenerative injectable approach integrating an immunotolerant scaffold‐forming collagen (Oligomer) with autologous motor‐endplate expressing (MEE ...

Dynamic properties of denervated rat muscle treated with electrotherapy
, 1963 Denervated rat gastrocnemii, compared with normal controls, showed slower shortening velocity and less shortening, performed less work, exhibited decreased values for Hill's constant a (shortening heat per centimeter shortening), a low P0 (maximum ...

Excitation-contraction coupling and mechano-sensitivity in denervated skeletal muscles
European Journal of Translational Myology, 2010 Skeletal muscle atrophy can be defined as a wasting or decrease in muscle mass and muscle force generation owing lack of use, ageing, injury or disease. Thus, the etiology of atrophy can be different.

PM&R, EarlyView.Abstract Introduction/Objective Diagnostic nerve blocks (DNBs) involve the injection of anesthetic around peripheral nerves to temporarily reduce motor tone. Although they are used clinically to inform spasticity treatment with neurotomy and chemodenervation, there is little research exploring the predictive nature of DNBs.
