Aim. To assess the dynamics of pain syndrome in patients with osteochondrosis of the lumbar spine using the method of mechanotherapy using the BIODEX SYSTEM 3 PRO Dual Position Back Ext / Flex apparatus with biofeedback. Materials and Methods. The analysis of the treatment of 27 patients with chronic and acute lumbodynia in the subacute stage was carried out. On the robotic complex BIODEX SYSTEM 3 PRO Dual Position Back Ext / Flex with biological feedback, the average value of the maximum torque was determined: 60 (Nm) for the flexors of the trunk, 155.5 (Nm) for the extensors of the trunk and 215.5 (Nm) for the muscles of the trunk (sum of the flexors and extensors of the trunk). Results. The main result of the work was to determine the safe torque at the time of the treatment procedure. For the flexor muscles of the trunk, the average values ranged from 40-90 Nm, for the extensor muscles of the trunk – from 50 to 300 Nm. Conclusions. Complex rehabilitation in patients with osteochondrosis of the lumbar spine using the robotic complex BIODEX SYSTEM 3 PRO Dual Position Back Ext / Flex with biofeedback allows to relieve local pain syndrome.

Hip Flexor

The hip flexor muscles are major contributors to lumbar spine stability. Tight hip flexors can lead to pain in the lumbar spine, and hence to an impairment in performance. Moreover, sedentary behavior is a common problem and a major contributor to restricted hip extension flexibility. Stretching can be a tool to reduce muscle tightness and to overcome the aforementioned problems. Therefore, the purpose of this systematic review with meta-analysis was to determine the effects of a single hip flexor stretching exercise on performance parameters. The online search was performed in the following three databases: PubMed, Scopus, and Web of Science. Eight studies were included in this review with a total of 165 subjects (male: 111; female 54). In contrast to other muscle groups (e.g., plantar flexors), where 120 s of stretching likely decreases force production, it seems that isolated hip flexor stretching of up to 120 s has no effect or even a positive impact on performance-related parameters. A comparison of the effects on performance between the three defined stretch durations (30–90 s; 120 s; 270–480 s) revealed a significantly different change in performance (p = 0.02) between the studies with the lowest hip flexor stretch duration (30–90 s; weighted mean performance change: −0.12%; CI (95%): −0.49 to 0.41) and the studies with the highest hip flexor stretch duration (270–480 s; performance change: −3.59%; CI (95%): −5.92 to −2.04). Meta-analysis revealed a significant (but trivial) impairment in the highest hip flexor stretch duration of 270–480 s (SMD effect size = −0.19; CI (95%) −0.379 to 0.000; Z = −1.959; p = 0.05; I2 = 0.62%), but not in the lowest stretch duration (30–90 s). This indicates a dose-response relationship in the hip flexor muscles. Although the evidence is based on a small number of studies, this information will be of great importance for both athletes and coaches.

Suppression Effects

It has been hypothesized that the magnocellular red nucleus (RNm) contributes to compensation for motor impairments associated with lesions of the pyramidal tract. To test this hypothesis, we used stimulus triggered averaging (StTA) of electromyographic (EMG) activity to characterize changes in motor output from the red nucleus after lesions of the pyramidal tract. Three monkeys were trained to perform a reach and prehension task. EMG activity was recorded from 11 forearm muscles including one elbow, five wrist, and five digit muscles. Microstimulation (20 μA at 20 Hz) was delivered throughout the movement task to compute StTAs. Two monkeys served as controls. In a third monkey, 65% of the left pyramidal tract had been destroyed by an electrolytic lesion method five years before recording. The results demonstrate a clear pattern of postlesion reorganization in red nucleus–mediated output effects on forearm muscles. The normally prominent extensor preference in excitatory output from the RNm (92% in extensors) was greatly diminished in the lesioned monkey (59%). Similarly, suppression effects, which are normally much more prominent in flexor than in extensor muscles (90% in flexors), were also more evenly distributed after recovery from pyramidal tract lesions. Because of the limited excitatory output from the RNm to flexor muscles that normally exists, loss of corticospinal output would leave control of flexors particularly weak. The changes in RNm organization reported in this study would help restore function to flexor muscles. These results support the hypothesis that the RNm is capable of reorganization that contributes to the recovery of forelimb motor function after pyramidal tract lesions.

Проведен анализ состояния периферического кровообращения у 28 мужчин, больных остеохондрозом поясничного отдела позвоночника, сопровождающегося люмбалгией с клинической симптоматикой нарушения периферического кровообращения нижних конечностей. Все больные, принимавшие участие в нашем исследовании, подписали информированное согласие на участие в программе и соглашение о неразглашении личных данных и протокола исследований. Критериями для анализа являлись изменения клинической симптоматики остеохондроза поясничного отдела позвоночника, обусловленной им люмбалгии и показателей оксиметрического исследования, которые были зафиксированы при первичном обращении и через 7 суток на фоне проводимого лечения и регрессии болевого синдрома. Таким образом, полученные результаты свидетельствовали о рефлекторном нарушении периферического кровообращения за счет развития патологического спинально-вазального тормозного рефлекса, обусловленного люмбалгией, которые восстанавливаются на фоне регрессии патологической импульсации в поясничном отделе позвоночника. Целесообразно продолжить исследования в этом направлении. The state of peripheral circulation in 28 men were analyzed, patients with osteochondrosis of the lumbar spine, accompanied by lumbodynia with clinical symptoms of impaired peripheral circulation of the lower extremities was carried out. All patients who took part in our study signed an informed consent to participate in the program and a non-disclosure agreement of personal data and research protocol. The criteria for the analysis were clinical symptoms of osteochondrosis of the lumbar spine caused by lumbodynia and indicators of oximetry studies, which were recorded during the initial visit and after 7 days amid treatment and regression of pain syndrome. Thus, the results indicated a reflex disorder of the peripheral circulation due to the development of a pathological spinal-vasal inhibitory reflex caused by lumbodynia, which is restored amid regression of pathological impulses in the lumbar spine. It is advisable to continue research in this direction.

Results of randomized prospective study with participation of 94 patients aged from 20 to 70 years with monosegmental lumbar spine lesions are presented. Minimum invasive surgical interventions were performed in 55 patients from the main group. Control group consisted of 39 patients in whom decompressive-stabilizing operations via conventional posteromedian approach with skeletization of posterior segments of vertebral column were performed. Average size of operative wound in open interventions more than 10 times exceeded that size in minimum invasive interventions and made up 484 ± 56 and 36 ± 12 sq.cm, respectively. Mean blood loss was 326.6 ± 278.0 ml in the main group and 855.1 ± 512.0 ml in the comparative one. In the main group no one patient required substitution hemotransfusion, while in 13 patients from the comparative group donor erythrocytic mass and/or fresh-frozen plasma were used to eliminate the deficit of blood components. Intensity of pain syndrome in the zone of surgical intervention by visual analog scale in the main group was lower than in comparative group. In the main and comparative groups the duration of hospitalization made up 6.1 ± 2.7 and 9.7 ± 3.7 bed days, respectively. In no one patient from the main group complications in the zone of operative wound were noted. Three patients from the comparative group required secondary debridement and in 1 patient early deep operative wound suppuration was observed. Application of low invasive surgical techniques for the treatment of patients with degenerative lumbar spine lesions enabled to perform radical surgical treatment with minimal iatrogenic injury. The method possessed indubitable advantages over the conventional open operations especially intraoperatively and in early postoperative period.

The paper presents the data of evaluation of dysfunction in lumbosacral pain in 898 athletes, ballet and circus artists aged 15 to 45 years. The median age was 25.8 year. 537 men and 361 women. In 409 people, pain syndrome is caused by osteochondrosis of the lumbar spine. 238 patients were diagnosed with spondylolysis of the lower lumbar vertebrae, 172 with facet syndrome, spondylarthrosis and 79 with pathology of the ligaments of the lumbosacral spine. Asymmetry in strength, tone of muscles-stabilizers of the spine and their bioelectric activity, which are eliminated in the course of treatment, was noted.

Propulsion Phase

Cats were trained to jump from a force platform to their maximum achievable heights. Vertical ground reaction forces developed by individual hindlimbs showed that the propulsion phase consists of two epochs. During the initial “preparatory phase' the cat can traverse many different paths. Irrespective of the path traversed, however, the cat always attains the same position, velocity and momentum at the end of this phase. Starting from this dynamic state the cat during the subsequent “launching phase' (about 150 ms long) generates significant propulsion as its hindlimbs develop force with identical, stereotypic profiles. Cinematographic data, electromyographic data, and computed torques about the hip, knee and ankle joints indicate that during the jump proximal extensor musculature is activated before distal musculature. During terminal experiments when the hindlimb was set at positions corresponding to those in the jump, isometric torques produced by tetanic stimulation of groups of extensor and flexor muscles were compared with computed torques developed by the same cat during previous jumps. These comparisons suggest that extensor muscles of the hindlimb are fully activated during the maximal vertical jump.

Knee Extensor Muscles

Context: All rehabilitative programs before anterior cruciate ligament (ACL) reconstructive surgery, which are focused on recovery of proprioception and muscular strength, are defined as prehabilitation. While it has shown that prehabilitation positively affects the overall outcome after ACL reconstruction, it is still controversial whether preoperatively enhancing quadriceps strength has some beneficial effect on postoperative strength, mainly during the first period. Objective: To determine whether there is any relationship between preoperative and early postoperative quadriceps strength. Design: Case control. Setting: University research laboratory. Participants: Fifty-nine males (18–33 y; age: 23.69 [0.71] y) who underwent ACL reconstruction with patellar-tendon autograft were examined the day before surgery, and at 60 and 90 days after surgery. Main Outcome Measures: The limb symmetry index (LSI) was quantified for maximal voluntary isometric contraction of the knee extensor muscles and of the knee flexor muscles at 90° joint angle. A k-means analysis was performed on either quadriceps or hamstrings LSI before surgery to classify the patients in high and low preoperative LSI clusters. Differences in postoperative LSI were then evaluated between the high and low preoperative LSI clusters. Results: Following surgery, there were no differences in the quadriceps LSI between patients with high and low preoperative quadriceps LSI. Sixty days after surgery, the hamstrings LSI was higher in patients with high than low preoperative hamstrings LSI (84.0 [13.0]% vs 75.4 [15.9]%; P < .05). Conclusions: Findings suggest that quadriceps strength deficit is related to the ACL injury and increases further after the reconstruction without any correlation between the preoperative and postoperative values. Therefore, it appears that there is no need to delay surgery in order to increase the preoperative quadriceps strength before surgery.
