Vibration

This study evaluates whether adding mechanical vibration to dry needling (DN+V) is not inferior to dry needling alone (DN) for reducing low back pain intensity in adults with nonspecific low back pain (NSLBP), when both interventions are combined with a structured exercise program. The primary hypothesis is non-inferiority in pain reduction (Numeric Pain Rating Scale, NPRS) at 1 week after treatment, using a non-inferiority margin of 1 point on the 0-10 NPRS scale. If non-inferiority is confirmed, secondary analyses will explore whether DN+V is superior to DN alone in patient-reported treatment acceptability, pain experienced during the intervention, and post-needling soreness. Participants will be randomly assigned to one of two parallel groups: DN plus exercise, or DN+V plus exercise. Outcomes will be assessed at baseline and at multiple time points up to 4 weeks after treatment, including pain intensity, disability, acceptability, muscle strength, pressure pain threshold, quality of life, and global impression of change. Direct and indirect costs associated with both interventions will also be collected to provide data for a future economic evaluation of the cost-effectiveness of DN+V compared with DN.

This prospective study is planned as a randomized controlled study. The aim of this study is to investigate the effects of vibration and the ShotBlocker method on pain and fear levels in children during intramuscular injection in the emergency department.

A medical professional trained in the procedure and use of the device will conduct the vibroacoustic therapy session. He will also take blood samples. In the control group, patients will undergo vibroacoustic pulmonary therapy in the "Pneumonia" mode, and in the control group, in the "Prevention" mode. Vibroacoustic pulmonary therapy will be conducted over a period of 5 days. A similar algorithm of actions is planned for both groups. VALT sessions will be conducted 4-6 times a day for 5 minutes in combination with treatment according to the protocol for the use of "Vibroacoustic Therapy" of the lungs of the Ministry of Health of the Republic of Kazakhstan. The device's emitters will be applied to the affected areas of the lungs. Since the device has long cords for the emitters and is portable, it is not difficult to change the patient's position and does not require their active participation, which is important for patients on ventilators and with limited mobility.

The aim of this study is to investigate the effects of Instrument-Assisted Soft Tissue Mobilization and vibration massage therapy on pain, functionality, and kinesiophobia in individuals with lumbar disc herniation.

The goal of this interventional cross-sectional study is to evaluate motor responses to non-invasive vibratory stimulation applied to the hamstring muscle tendons in healthy individuals. Knee flexion and extension efforts, in both isometric and concentric contractions, will be tested. The investigators hypothesize that vibratory stimulation causes an increase in activity in the flexor muscles (hamstrings) and a decrease in the extensor muscles (quadriceps) of the knee in all motor tasks. It follows that during knee flexion (both concentric and isometric), vibratory stimulation should cause an increase in the distance between the angular trajectories of the knee obtained with and without vibratory stimulation (with a positive sign). The increased activity of the hamstring muscles would, in fact, contribute to increasing the velocity of the flexor movement. Conversely, during extensor movements (both concentric and isometric), vibratory stimulation should reduce the instantaneous velocity of the movement, therefore causing an increase in distance (with a negative sign) between the trajectories obtained with and without stimulation. Participants will be tested using an isokinetic dynamometer and they will be asked to perform the following motor tasks in a random order: concentric knee flexion, concentric knee extension, isometric knee flexion, and isometric knee extension. The dominant limb will be tested, only. The assessment will be performed one time.

In the proposed research, we will assess motor and sensory functions of the hand using clinical tests and a tool designed to measure manual dexterity combined with vibrotactile stimulation. We will also evaluate the integrity of brain structure and function using MRI.
