(1/2296) Brain activation during maintenance of standing postures in humans.

The regulatory mechanism of bipedal standing in humans remains to be elucidated. We investigated neural substrates for maintaining standing postures in humans using PET with our mobile gantry PET system. Normal volunteers were instructed to adopt several postures: supine with eyes open toward a target; standing with feet together and eyes open or eyes closed; and standing on one foot or with two feet in a tandem relationship with eyes open toward the target. Compared with the supine posture, standing with feet together activated the cerebellar anterior lobe and the right visual cortex (Brodmann area 18/19), and standing on one foot increased cerebral blood flow in the cerebellar anterior vermis and the posterior lobe lateral cortex ipsilateral to the weight-bearing side. Standing in tandem was accompanied by activation within the visual association cortex, the anterior and posterior vermis as well as within the midbrain. Standing with eyes closed activated the prefrontal cortex (Brodmann area 8/9). Our findings confirmed that the cerebellar vermis efferent system plays an important role in maintenance of standing posture and suggested that the visual association cortex may subserve regulating postural equilibrium while standing.  (+info)

(2/2296) Antinociceptive properties of the new alkaloid, cis-8, 10-di-N-propyllobelidiol hydrochloride dihydrate isolated from Siphocampylus verticillatus: evidence for the mechanism of action.

The antinociceptive action of the alkaloid cis-8, 10-di-n-propyllobelidiol hydrochloride dehydrate (DPHD), isolated from Siphocampylus verticillatus, given i.p., p.o., i.t., or i.c.v., was assessed in chemical and thermal models of nociception in mice, such as acetic acid-induced abdominal constriction, formalin- and capsaicin-induced licking, and hot-plate and tail-flick tests. DPHD given by i.p., p.o., i.t., or i.c.v. elicited significant and dose-related antinociception. At the ID50 level, DPHD was about 2- to 39-fold more potent than aspirin and dipyrone, but it was about 14- to 119-fold less potent than morphine. Its analgesic action was reversed by treatment of animals with p-chlorophenylalanine, naloxone, cyprodime, naltrindole, nor-binaltrorphimine, L-arginine, or pertussis toxin. Its action was also modulated by adrenal-gland hormones but was not affected by gamma-aminobutyric acid type A or type B antagonist, bicuculine, or phaclofen, nor was it affected by glibenclamide. DPHD, given daily for up to 7 days, did not develop tolerance to itself nor did it induce cross-tolerance to morphine. However, animals rendered tolerant to morphine presented cross-tolerance to DPHD. The antinociception of DPHD was not secondary to its anti-inflammatory effect, nor was it associated with nonspecific effects such as muscle relaxation or sedation. DPHD, in contrast to morphine, did not decrease charcoal meal transit in mice, nor did it inhibit electrical field stimulation of the guinea pig ileum or mouse vas deferens in vitro. Thus, DPHD produces dose-dependent and pronounced systemic, spinal, and supraspinal antinociception in mice, including against the neurogenic nociception induced by formalin and capsaicin. Its antinociceptive effect involves multiple mechanisms of action, namely interaction with mu, delta, or kappa opioid systems, L-arginine-nitric oxide and serotonin pathways, activation of Gi protein sensitive to pertussis toxin, and modulation by endogenous glucocorticoids.  (+info)

(3/2296) Incidence and causes of tenosynovitis of the wrist extensors in long distance paddle canoeists.

OBJECTIVES: To investigate the incidence and causes of acute tenosynovitis of the forearm of long distance canoeists. METHOD: A systematic sample of canoeists competing in four canoe marathons were interviewed. The interview included questions about the presence and severity of pain in the forearm and average training distances. Features of the paddles and canoes were determined. RESULTS: An average of 23% of the competitors in each race developed this condition. The incidence was significantly higher in the dominant than the nondominant hand but was unrelated to the type of canoe and the angle of the paddle blades. Canoeists who covered more than 100 km a week for eight weeks preceding the race had a significantly lower incidence of tenosynovitis than those who trained less. Environmental conditions during racing, including fast flowing water, high winds, and choppy waters, and the paddling techniques, especially hyperextension of the wrist during the pushing phase of the stroke, were both related to the incidence of tenosynovitis. CONCLUSION: Tenosynovitis is a common injury in long distance canoeists. The study suggests that development of tenosynovitis is not related to the equipment used, but is probably caused by difficult paddling conditions, in particular uneven surface conditions, which may cause an altered paddling style. However, a number of factors can affect canoeing style. Level of fitness and the ability to balance even a less stable canoe, thereby maintaining optimum paddling style without repeated eccentric loading of the forearm tendons to limit hyperextension of the wrist, would seem to be important.  (+info)

(4/2296) Effects of physical and sporting activities on balance control in elderly people.

OBJECTIVE: Balance disorders increase with aging and raise the risk of accidental falls in the elderly. It has been suggested that the practice of physical and sporting activities (PSA) efficiently counteracts these age related disorders, reducing the risk of falling significantly. METHODS: This study, principally based on a period during which the subjects were engaged in PSA, included 65 healthy subjects, aged over 60, who were living at home. Three series of posturographic tests (static, dynamic with a single and fast upward tilt, and dynamic with slow sinusoidal oscillations) analysing the centre of foot pressure displacements or electromyographic responses were conducted to determine the effects of PSA practice on balance control. RESULTS: The major variables of postural control were best in subjects who had always practised PSA (AA group). Those who did not take part in PSA at all (II group) had the worst postural performances, whatever the test. Subjects having lately begun PSA practice (IA group) had good postural performances, close to those of the AA group, whereas the subjects who had stopped the practice of PSA at an early age (AI group) did not perform as well. Overall, the postural control in the group studied decreased in the order AA > IA > AI > II. CONCLUSIONS: The period during which PSA are practised seems to be of major importance, having a positive bearing on postural control. It seems that recent periods of practice have greater beneficial effects on the subject's postural stability than PSA practice only at an early age. These data are compatible with the fact that PSA are extremely useful for elderly people even if it has not been a lifelong habit.  (+info)

(5/2296) Receptor binding, behavioral, and electrophysiological profiles of nonpeptide corticotropin-releasing factor subtype 1 receptor antagonists CRA1000 and CRA1001.

Receptor binding, behavioral, and electrophysiological profiles of 2-[N-(2-methylthio-4-isopropylphenyl)-N-ethylamino]-4-[4-(3-flu orophe nyl)-1,2,3,6-tetrahydropyridin-1-yl)-6-methylpyrimidine (CRA1000) and 2-[N-(2-bromo-4-isopropylphenyl)-N-ethylamino]-4-[4-(3-fluoropheny l)- 1,2,3,6-tetrahydropyridin-1-yl)-6-methylpyrimidine (CRA1001), putative novel and selective antagonists for corticotropin-releasing factor1 (CRF1) receptor were examined. Both CRA1000 and CRA1001 inhibited 125I-ovine CRF binding to membranes of rat frontal cortex with IC50 values of 20.6 and 22.3 nM, respectively. Likewise, CRA1000 and CRA1001 inhibited 125I-ovine CRF binding to membranes of rat pituitary. In contrast, both CRA1000 and CRA1001 were without affinity for the CRF2beta receptor when examined using rat heart. In mice orally administered CRA1000 and CRA1001 reversed the swim stress-induced reduction of the time spent in the light area in the light/dark exploration task. In nonstress conditions, CRA1000 and CRA1001 were without effect on the time spent in the light area in the same task in mice. Orally administered CRA1000 and CRA1001 dose dependently reversed the effects of i.c.v. infusion of CRF on time spent in the open arms in the elevated plus-maze in rats. Lesioning of olfactory bulbs induced hyperemotionality, and this effect was inhibited by either acute or chronic oral administration of CRA1000 and CRA1001 in rats. The firing rate of locus coeruleus neurons was increased by i.c.v.-infused CRF. This excitation of locus coeruleus neurons was significantly blocked by pretreatment with i.v. administration of CRA1000 and CRA1001. CRA1000 and CRA1001 had no effects on the hexobarbital-induced anesthesia in mice, the rotarod test in mice, the spontaneous locomotor activity in mice, and a passive avoidance task in rats. These observations indicate that both CRA1000 and CRA1001 are selective and competitive CRF1 receptor antagonists with potent anxiolytic- and antidepressant-like properties in various experimental animal models, perhaps through inhibition of CRF1 receptors. CRA1000 and CRA1001 may prove effective for treating subjects with depression- and/or anxiety-related disorders without the side effects seen in the related currently prescribed medications.  (+info)

(6/2296) Phenotypic variation in sensorimotor performance among eleven inbred rat strains.

As a first step toward identifying the genes that determine sensorimotor ability (motor coordination) we subjected 11 inbred strains of rats to three different tests for this trait. Rats were tested at 13 wk of age to determine how long they could remain on 1) a rotating cylinder as the velocity of rotation increased every 5 s (1-direction rotation test), 2) a rotating cylinder that reversed direction every 5 s and increased velocity every 10 s (2-direction rotation test), and 3) a platform that was tilted 2 degrees every 5 s from 22 to 47 degrees (tilt test). On all three tests, rats of the PVG strain demonstrated the greatest sensorimotor ability. In contrast, rats of the MNS strain were most often represented among the group of strains that demonstrated the lowest performance on all tests. Considering all three tests, there was a 3- to 13-fold range in sensorimotor performance between the highest and lowest strains. This large divergence between the highest and lowest strains provides a genetic model that can be used to identify intermediate phenotypes and quantitative trait loci that contribute to sensorimotor ability.  (+info)

(7/2296) Emergence of postural patterns as a function of vision and translation frequency.

Emergence of postural patterns as a function of vision and translation frequency. We examined the frequency characteristics of human postural coordination and the role of visual information in this coordination. Eight healthy adults maintained balance in stance during sinusoidal support surface translations (12 cm peak to peak) in the anterior-posterior direction at six different frequencies. Changes in kinematic and dynamic measures revealed that both sensory and biomechanical constraints limit postural coordination patterns as a function of translation frequency. At slow frequencies (0.1 and 0.25 Hz), subjects ride the platform (with the eyes open or closed). For fast frequencies (1.0 and 1.25 Hz) with the eyes open, subjects fix their head and upper trunk in space. With the eyes closed, large-amplitude, slow-sway motion of the head and trunk occurred for fast frequencies above 0.5 Hz. Visual information stabilized posture by reducing the variability of the head's position in space and the position of the center of mass (CoM) within the support surface defined by the feet for all but the slowest translation frequencies. When subjects rode the platform, there was little oscillatory joint motion, with muscle activity limited mostly to the ankles. To support the head fixed in space and slow-sway postural patterns, subjects produced stable interjoint hip and ankle joint coordination patterns. This increase in joint motion of the lower body dissipated the energy input by fast translation frequencies and facilitated the control of upper body motion. CoM amplitude decreased with increasing translation frequency, whereas the center of pressure amplitude increased with increasing translation frequency. Our results suggest that visual information was important to maintaining a fixed position of the head and trunk in space, whereas proprioceptive information was sufficient to produce stable coordinative patterns between the support surface and legs. The CNS organizes postural patterns in this balance task as a function of available sensory information, biomechanical constraints, and translation frequency.  (+info)

(8/2296) Energy expenditure and balance during spaceflight on the space shuttle.

The objectives of this study were as follows: 1) to measure human energy expenditure (EE) during spaceflight on a shuttle mission by using the doubly labeled water (DLW) method; 2) to determine whether the astronauts were in negative energy balance during spaceflight; 3) to use the comparison of change in body fat as measured by the intake DLW EE, 18O dilution, and dual energy X-ray absorptiometry (DEXA) to validate the DLW method for spaceflight; and 4) to compare EE during spaceflight against that found with bed rest. Two experiments were conducted: a flight experiment (n = 4) on the 16-day 1996 life and microgravity sciences shuttle mission and a 6 degrees head-down tilt bed rest study with controlled dietary intake (n = 8). The bed rest study was designed to simulate the flight experiment and included exercise. Two EE determinations were done before flight (bed rest), during flight (bed rest), and after flight (recovery). Energy intake and N balance were monitored for the entire period. Results were that body weight, water, fat, and energy balance were unchanged with bed rest. For the flight experiment, decreases in weight (2.6 +/- 0.4 kg, P < 0.05) and N retention (-2. 37 +/- 0.45 g N/day, P < 0.05) were found. Dietary intake for the four astronauts was reduced in flight (3,025 +/- 180 vs. 1,943 +/- 179 kcal/day, P < 0.05). EE in flight was 3,320 +/- 155 kcal/day, resulting in a negative energy balance of 1,355 +/- 80 kcal/day (-15. 7 +/- 1.0 kcal. kg-1. day-1, P < 0.05). This corresponded to a loss of 2.1 +/- 0.4 kg body fat, which was within experimental error of the fat loss determined by 18O dilution (-1.4 +/- 0.5 kg) and DEXA (-2.4 +/- 0.4 kg). All three methods showed no change in body fat with bed rest. In conclusion, 1) the DLW method for measuring EE during spaceflight is valid, 2) the astronauts were in severe negative energy balance and oxidized body fat, and 3) in-flight energy (E) requirements can be predicted from the equation: E = 1.40 x resting metabolic rate + exercise.  (+info)



Instability


  • Among the risk factors involved in postural genesis of occupational low back pain is work in uncomfortable positions, such as maintenance of static postures for long periods of time and frequent implementation of flexion, extension and trunk rotation.The association between body instability (lack of postural balance) and back pain is seen with some frequency, especially in working groups. (clinicaltrials.gov)
  • On the other hand, hip and ankle strategies have been predicted by minimizing postural instability and deviation from upright posture. (physiology.org)
  • We hypothesize that the relative importance of minimizing mechanical work vs. postural instability influences the strategy used to restore upright posture. (physiology.org)
  • Furthermore, a continuum of ankle and hip strategies was predicted in simulation when changing the relative importance of minimizing mechanical work and postural instability, with increased weighting of mechanical work resulting in an ankle strategy. (physiology.org)
  • In conclusion, the combination of experimental measurements and predictive simulations of the postural response to a backward support surface translation showed that the trade-off between effort and postural instability minimization can explain the selection of a specific postural response in the continuum of potential ankle and hip strategies.
