“…The phenomenon of compensation of motor organs in the human body is viewed as an ability to replace (through recovery) the function lost by the damaged organ or taking over this function entirely by another healthy organ [1]. The key role in the process is played by specific control and plasticity of the nervous system [2, 3]. In clinical practice, compensation of motor organ dysfunction is often divided into external compensation (e.g., the use of orthopaedic aids) and internal compensation (e.g., when a subject with a shorter lower limb moves on their toes) [4].…”

Background. The complexity of the structure and function of a living body can be affected by disorders and can cause various dysfunctions. Objective. The aim of this study was to determine compensatory mechanisms in subjects with drop foot during gait. Methods. The study evaluated 10 subjects with drop foot (DF) whose results were compared to a group of 10 healthy controls (C). Spatiotemporal, kinematic, and kinetic parameters during the gait cycle were collected using Vicon system synchronized with Kistler platforms. Results. Spatiotemporal, kinematic, and kinetic parameters were significantly different between the analysed groups. In the DF group, the subjects walked almost 47% slower and performed 60% less steps per minute compared to the C group. The main problem in the DF group was insufficient ankle dorsiflexion in the 0–10% of the gait cycle. Mean values in the groups during the first 10% of the gait cycle were as follows: DF (−10.42 ± 5.7°) and C (−2.37 ± 1.47°), which affected the substantial differences in the values of muscle torque: DF (0.2 ± 0.1 Nm/kg) and C (−0.26 ± 0.06 Nm/kg). Conclusions. Comparative analysis for joint angles and torques demonstrated that the mechanism of compensation is the most noticeable in the knee joint and less in the hip joint.

“…That might be associated with neural reflex receptors such as Pacinian and Messinian corpuscles on the plantar skin, which are sensitive to vibration. The Pacinian receptor could mediate vibrotactile sensations under high-frequency vibration (Madhavan et al 2006, Ye and Griffin 2014, Kim et al 2016. Because the intensities and magnitudes of the LV in this study were low (1 mm amplitude, peak to peak 2 mm, 1g peak acceleration), 100 Hz vibration could activate Pacinian corpuscles and induce a relative neural reflex while 35 Hz vibration could not (Ye and Griffin 2014).…”

“…In this study, the case of high-frequency LV applied to the skin over the first metatarsal head is different from the situation where there is industrial injury due to transmitted vibration from a hand-held device-the intensity of such high-frequency vibration may enhance sympathetic activation to induce exaggerated vasoconstriction (Mester et al 2006, Mahbub andHarada 2008). There are various applications of LV with frequencies from 5 Hz to 300 Hz in the lower limbs (Madhavan et al 2006, Kim et al 2016, Strzalkowski et al 2016, Germann et al 2018, Souron et al 2018. Madhavan found that plantar vibration (30-60 Hz frequency, 0.2g peak to peak acceleration) could enhance the activity of Type IIA muscle fibers in the legs (Madhavan et al 2006).…”

“…The Pacinian channel can mediate vibrotactile sensations at higher frequencies (more than 63 Hz). Several studies have applied high-frequency LV to the plantar foot to improve lower limb muscle force, muscle reaction time and balance (Harrington and Hunter Downs 2001, Ye and Griffin 2014, Kim et al 2016, Strzalkowski et al 2016. Low-intensity LV at high frequency (>100 Hz) has also been used to study responses of the Pacinian mechanoreceptor.…”

“…Pacinian corpuscles are sensitive to higher-frequency vibrations around 60-300 Hz (Harrington and Hunter Downs 2001, Madhavan et al 2006, Ye and Griffin 2014. Some studies have applied LV on the plantar foot at high frequencies (>100 Hz) and demonstrated an increase in muscle force (Kim et al 2016, Germann et al 2018. Studies have also shown that frequencies higher than 125 Hz may cause a vasoconstrictive response (Ye and Griffin 2014).…”

Objective: The objectives of this study were to investigate the response of plantar skin blood flow (SBF) to different frequencies of local vibration (LV) and investigate the mechanisms of blood flow control in response to the different frequencies of LV using wavelet analysis. Approach: Twelve healthy participants were recruited to test the effects of three frequencies [0 Hz (sham control), 35 Hz and 100 Hz at 1 mm amplitude] of 10 min LV on the skin of the right first metatarsal head. A repeated measures design was used in this study and the order of vibration frequencies was randomly assigned to participants while they lay on a mat table. Laser Doppler flowmetry was used to measure SBF on the first metatarsal head before and after LV for 10 min. SBF after vibration was expressed as a ratio of SBF before vibration. Wavelet analysis was used to characterize changes in SBF control mechanisms. Main results: Our results showed that the SBF with the 100 Hz protocol (1.56 ± 0.19) was significantly higher than for the 35 Hz (1.29 ± 0.18, p < 0.05) and 0 Hz (0.85 ± 0.11, p < 0.01) protocols. Wavelet analysis demonstrated that metabolic endothelial control (SBF oscillations of 0.0095–0.02 Hz) and neurogenic control (SBF oscillations of 0.02–0.05 Hz) were associated with the increase in SBF after LV at 100 Hz. Significance: LV at 100 Hz results in a significant increase in SBF compared with 35 Hz and 0 Hz vibrations. Such an increase in SBF is related to the regulation of metabolic endothelial (0.0095–0.02 Hz) and neurogenic (0.02–0.05 Hz) controls. This is the first study to demonstrate that 100 Hz LV stimulates an increase in plantar SBF compared with 35 Hz and 0 Hz vibrations through the frequency intervals of 0.0095–0.02 and 0.02–0.05 Hz of SBF oscillations.
