“…Sensorimotor function was also evaluated by knee joint positional error using a passive-active angle reproduction test (tibial bubble inclinometer (Fabrication Enterprises, Inc., USA)) conducted at 25° and 60° of knee flexion and described in detail elsewhere. [19][20][21] Joint position error was recorded as the mean angular discrepancy from the target during three replicates at each of the two target knee angles, performed in random order (six trials, 15 seconds inter-trial recovery), using the following expression (absolute values of estimated errors were used for analysis):…”

“…Unilateral balance performance had been altered only at 24 h after EIMD, coinciding with peak alterations to PF and DOMS [24], with the authors speculating that efficient regulation of movement is routine in the presence of less severe damage and that proprioceptive function is only compromised under extremes of exercise-related stress. The preservation of normal muscle activation latencies [3,24,31] might highlight a protective conservation of biological resources and enhanced emergency reflex processes. Future studies should focus attention on whether other and more potent methods for delivering SR (for example, functional electrical stimulation) amongst episodes of EIMD might offer greater efficacy and effectiveness in enhancing sensorimotor performance under adverse conditions of exercise stress and strain responses.…”

“…Impairment to skeletal muscle function following exercise induced muscle damage (EIMD) and during prolonged exposure to eccentric contractions is associated with symptoms that include delayed onset muscle soreness (DOMS), loss of flexibility [3], altered neuromuscular and sensorimotor performance [4][5][6] and may contribute to lower limb injuries during sporting activities. An inability of m. biceps femoris to function optimally and counter excessive knee' anterior shear stress may leave it susceptible to injury [7].…”

“…Sensorimotor performance and the ability to scale volitional force and joint position precisely [3], relies on the integration of afferent information from peripheral mechanoreceptors, central processing and efferent information to marshal effective muscular activation and joint acuity [8]. Outcomes of joint position sense (JPS) and force error (FE) [3,9] have been used in clinical research for its assessment.…”

“…Outcomes of joint position sense (JPS) and force error (FE) [3,9] have been used in clinical research for its assessment. Mechanisms underpinning EIMD-related derangement of sensorimotor performance in which subjects consistently undershoot target forces and incorrectly estimate joint angles [5,10], include alteration to peripheral mechanoreceptor sensitivity, changes in muscle spindle signaling and reflex sensitivity [1,4], and alteration to central methods of processing and perceptual sense of effort [11,12].…”

Abstract:The aim of this study was to assess the effects of stochastic resonance (SR) stimulation on sensorimotor performance during an episode of exercise-induced muscle damage (EIMD). Thirty four men (age: 21.3 (±2.6) years; height 1.78 (±0.06) m; body mass 72.3 (±7.4) kg (mean (±SD)) gave their informed consent to participate in this study.Sensorimotor performance (error in replicating a target force) of the knee flexors was assessed prior to, and at 0.5 and 48 h after (i) a treatment condition involving a single-leg EIMD conditioning of the non-preferred leg, with concomitant responses to (ii) randomised presentation of SR, no SR and placebo conditions. Results showed a significant ANOVA interaction for sensorimotor performance amongst factors of condition (control period; EIMD), time (pre; post 0.5 h; post 48 h) and stimuli (SR; no SR; placebo) (F [1.5,29.3] = 5.7; p < 0.01). While scores during an antecedent control period had remained relatively constant, the EIMD protocol had elicited increased error in replicating a target force for the knee flexors of the non-preferred leg over time (worsened sensorimotor performance) that had been most prominent at 48 h after exercise, but whose negative effects had been ameliorated under conditions of SR (5.6 ± 3.1% (no SR) versus 3.7 ± 2.3% (SR) (pre) and 10.3 ± 4.2% (no SR) versus 8.1 ± 5.1% (SR) (48 h), respectively; F [1,36] = 6.0; p < 0.01). In conclusion, this study has shown that SR conditioning-related increases in the sensorimotor performance of the hamstring muscle group led to some protection from performance loss following EIMD.

The effects of flexibility conditioning on neuromuscular and sensorimotor performance were assessed near to full knee extension (25°). Eighteen males who were randomly assigned into two groups underwent eight weeks (three-times per week) of flexibility conditioning (hip region/knee flexor musculature; dominant limb) involving either proprioceptive neuromuscular facilitation (PNF) (n=9) or passive stretching (PASS) (n=9). Both modes of flexibility conditioning are popular within contemporary exercise and clinical settings and have demonstrated efficacy in improving range of motion. The contralateral limb and a prior 'no exercise' condition were used as controls. The PNF and PASS modes of conditioning improved passive hip flexibility to a similar extent (mean 19.3% vs. baseline, intervention limb, p<0.01) but did not alter knee flexor strength (overall mean 309.6±81 N) or sensorimotor performance (force and positional errors: 2.3±8.2% and 0.48±7.1%). Voluntary and magnetically evoked electromechanical delays (EMDV and EMDE, respectively) were increased but to a greater extent following PASS compared to PNF (PASS: 10.8% and 16.9% lengthening of EMDV and EMDE, respectively vs. PNF: 3.2% and 6.2%, p<0.01).The attenuated change to electromechanical delay (EMD) performance during PNF conditioning suggests a preserved capability for rapid muscle activation, which is important in the maintenance of dynamic joint stability. That PNF was also equally efficacious in flexibility conditioning would suggest that this mode of flexibility training should be used over passive to help preserve dynamic joint stability capabilities at this extended and vulnerable joint position.
