“…However, few studies involving the quantitative evaluation of LR by MUNIX have been reported. Recently published studies confirmed that MUNIX in the lower limbs can be recorded reliably from the abductor hallucis (AH), the extensor digitorum brevis (EDB) and the tibialis anterior (TA); these muscles are most commonly affected in LR because up to 80% of LR involve the L5 and/or S1 roots …”

Introduction:We investigated the feasibility of motor unit number index (MUNIX) in quantitatively assessing motor root lesions and tracking different treatment outcomes in lumbosacral radiculopathy (LR).Methods: Bilateral MUNIX was recorded from the abductor hallucis, extensor digitorum brevis, and tibialis anterior in 44 normal controls and 108 patients with LR, and this was repeated approximately 12 months after treatment in 60 patients with LR.

“…The inclusion criteria for patients with LDH includes [13,14] (1) low back discomfort with referral of pain or paresthesias into a single lower limb following an L4/L5/S1 distribution pattern; (2) lumbosacral magnetic resonance imaging (MRI) or computer tomography (CT) that demonstrated unilateral L4/L5/S1 nerve root compression by herniated disc at the L3/4, L4/L5 or L5/S1 level; (3) conventional electrophysiologic studies including normal sensory nerve conduction studies and a needle EMG revealing the presence of disease only on the involved side of abnormal spontaneous activity and/or changes in motor unit action potential in muscles that were innervated by the involved L4/L5/S1 root. (4) Surgical ndings of unilateral compressed herniated discs at the L4/L5/S1 root on the involved side. (5) Postoperative drain for 3 days.…”

“…Lumbar disc herniation (LDH) is a degenerative pathology, and it was estimated that approximately 70-80% of the adult population will be affected by this disease during their lifetime [1,2]. Lumbosacral radiculopathy caused by LDH always carries a series of signs and symptoms and often leads to surgical intervention when conservative management fails [2][3][4]. Traditional open discectomy through unilateral interlaminar approach has obtained satisfactory results [5,6].…”

Background: Approximately one-third patients with lumbar disc herniation (LDH) showed postoperative reactive pain, and this reactive pain may be related to the postoperative increased release of inflammatory mediators. Percutaneous transforaminal endoscopic discectomy (PTED) can obviously reduce the intraoperative soft tissue trauma. The aim of this study is to investigate the reactive pain in LDH patients undergoing PTED compared with open discectomy. Material and methods: This study retrospectively included 72 patients (PTED vs. open discectomy: 41 vs. 31), and the incidence of reactive pain, as well as both the extent and duration of reactive pain, were evaluated. Furthermore, inflammation related markers in both blood and drainage fluid samples, including white blood cell (WBC) count, C-reactive protein (CRP), creatine kinase (CK), interleukin-6 (IL-6) and IL-1β, were tested before and after operation. Results: Significantly greater number of patients undergoing open discectomy showed reactive pain compared to those undergoing PTED (13/31, 41.9% vs. 7/41, 17.0%; P < 0.05), and the duration of reactive pain is mildly longer in the former (P < 0.05). In both patient groups, the patients with reactive pain showed increased IL-6 and IL-1β in drainage fluid, as well as increased IL-6 in blood samples (P < 0.05), and there is significant correlation between the inflammation markers in drainage fluid and both duration and extent of reactive pain in both patient groups (P < 0.05). Conclusions: Local inflammatory substance accumulation may be potential cause for postoperative reactive pain, and PTED may reduce this inflammatory accumulation at the surgical site and subsequently reduce the risk of reactive pain. Trial registration: This retrospective cohort analysis was retrospectively registered at September 9, 2020.

“…The first category contains the diseases that involve long distances of nerves, such as peripheral neuropathy due to diabetes [ 3 , 4 ] or multifocal motor neuropathy [ 5 ]. The second category contains the diseases involving the proximal part of the nerve pathway while the distal part is healthy, such as radiculopathies [ 6 ] and plexopathies [ 7 ].…”

Evaluation of dynamic F wave parameters before and after physical activity in normal population

Objectives F wave is one of the nerve conduction studies, mainly used to study the proximal pathway of peripheral nerves. One of its applications is dynamic assessment, i.e., before and after physical activity, when symptoms develop in some patients. Best to our knowledge, few studies evaluate normal dynamic F wave values in healthy individuals. This study aims to determine and compare normal values of several parameters of Compound Muscle Action Potential (CMAP) and F waves of tibial nerves dynamically before and after physical activity in the lower extremities of 34 normal subjects. These parameters were recorded before and after 15 min of continuous walking at intervals of 1, 5, and 10 min after the end of physical activity. Results Normal values of CMAP onset latency and amplitude, minimum, maximum, and mean latency of 10 F waves, F chronodispersion, and F persistence were dynamically collected before and during 10 min after physical activity in three phases. Some of the parameters showed significant changes (P < 0.05). Although physical activity showed statistically significant effects on some CMAP and F wave parameters (especially F chronodispersion) in normal subjects, none of them exceeded the normal clinical values introduced in the literature.
