Text neck is not associated with neck and upper limb disability in young adults who use smartphones.

Purpose: The objective of the present study was to correlate neck and upper-limb disabilities with neck flexion in university students who are smartphone users. While handling smartphones, a posture with sustained neck flexion known as "Text Neck" is usually adopted, and some authors related to musculoskeletal symptoms on the neck and the upper limb. However, recent studies state that such an association is questionable.

Effectiveness of electrophysical agents for treating pressure injuries: a systematic review.

Tissue injuries that affect the skin and/or adjacent tissues and are usually over a bony prominence are called pressure injuries. The prevalence of these dysfunctions remains high, and despite technological advances, there is no consensus on the most appropriate treatment. The objective of this review was to evaluate the efficacy of photobiomodulation (PBM), ultrasound, and high-frequency electrophysical agents in the healing of pressure injuries in adults and the elderly.

Physiotherapeutic approach in seamstresses with neck pain: A single-blind, randomized clinical trial.

Purpose: To investigate and compare the effects of therapeutic exercise, therapeutic ultrasound and photobiomodulation on pain, functionality and recruitment pattern of motor units, after a rehabilitation protocol for seamstresses with neck pain.

Materials And Methods: All 36 female, randomly divided into three groups; i)exercise control group, ii)exercise and photobiomodulation group, iii)exercise and ultrasound group. The groups were composed of sewing machine operators with complaints neck pain.

Effects of photobiomodulation on different application points and different phases of complex regional pain syndrome type I in the experimental model.

Background: Complex regional pain syndrome type I (CRPS-I) consists of disorders caused by spontaneous pain or induced by some stimulus. The objective was to verify the effects of photobiomodulation (PBM) using 830 nm wavelength light at the affected paw and involved spinal cord segments during the warm or acute phase.

Methods: Fifty-six mice were randomized into seven groups.

Viability of transverse rectus abdominis musculocutaneous flap treated with photobiomodulation and therapeutic ultrasound: an experimental model.

Unlabelled: Report the effects of photobiomodulation (PBM) and therapeutic ultrasound (TUS) on the viability of TRAM in mice.

Materials And Methods: Fifty-five mice Swiss were subjected to treatment for 5 days. Group 1, treatment was performed with the agents switched off.

Comparison of photobiomodulation in the treatment of skin injury with an open wound in mice.

This study aimed to investigate the effects of photobiomodulation at a wavelength of 660 and 830 nm at different numbers of application points in the healing of open wounds in mice. In total, 120 mice were divided into 10 groups. The animals were submitted to cutaneous lesion of the open wound type (1.

Dry Needling and Photobiomodulation Decreases Myofascial Pain in Trapezius of Women: Randomized Blind Clinical Trial.

Objective: The purpose of this study was to assess whether dry needling (DN) added to photobiomodulation (PBM) has effects on the treatment of active myofascial trigger points in the upper trapezius.

Methods: This study was a randomized clinical trial, with 43 participants divided into 3 groups: DN and PBM (DNP), DN, and DN outside of the trigger point (DNout). Each group received 1 session of DN followed by PBM therapy with the machine turned on or off.

Photobiomodulation promotes neural regeneration when compared to simvastatin treatment in a sciatic nerve crush model.

To determine whether the effects of photobiomodulation (PBM) were associated with the use of Simvastatin in the functional recovery from sciatic nerve in mice submitted to crush injury. Fifty Swiss mice (approximately 3 months old; average weight 40 g) were randomly divided into six groups: naive, sham, control, PBM (660 nm, 10 J/cm; 30 mW; 0.6 J per day for 28 days; 0.

Effects of Photobiomodulation Therapy and Restriction of Wrist Extensor Blood Flow on Grip: Randomized Clinical Trial.

To evaluate the influence of two different photobiomodulation therapy (PBMT) protocols (red 660 nm vs. infrared 830 nm) combined with a blood flow restriction (BFR) training protocol in wrist extensor muscles on handgrip, wrist extension force, and electromyographic behavior [root mean square (RMS)]. PBMT has been widely used to increase muscle performance and recovery in recent clinical trials.

Effects of a Pilates protocol in individuals with non-specific low back pain compared with healthy individuals: Clinical and electromyographic analysis.

Background: Electromyography may be useful for assessing and understanding trunk muscle activation, and Pilates is commonly used as a treatment for low back pain. The objective of this study was to verify electromyography of trunk muscles after a Pilates protocol in individuals with non-specific low back pain and in healthy individuals.

Methods: Volunteers were divided into two groups: non-specific low back pain (n = 19) and clinically healthy (n = 16) groups.

Comparative effect of photobiomodulation associated with dexamethasone after sciatic nerve injury model.

To analyze the effect of photobiomodulation and dexamethasone on nerve regeneration after a sciatic nerve crushing model. Twenty-six Swiss mice were divided into the following groups: naive; sham; injured, low-level laser therapy (LLLT) (660 nm, 10 J/cm, 0.6 J, 16.

Diagnostic accuracy of the electromyography parameters associated with anterior knee pain in the diagnosis of patellofemoral pain syndrome.

Objective: To assess the diagnostic accuracy of the surface electromyography (sEMG) parameters associated with referred anterior knee pain in diagnosing patellofemoral pain syndrome (PFPS).

Design: Sensitivity and specificity analysis.

Setting: Physical rehabilitation center and laboratory of biomechanics and motor control.

Comparison of different analysis techniques for the determination of muscle onset in individuals with patellofemoral pain syndrome.

To understand patellofemoral pain syndrome (PFPS), recent studies have focused on assessing the onset in the vastus medialis and vastus lateralis to determine whether there is a delay between these muscles' activation. However, the results of these studies are not in agreement, as some research shows that there is a delay in the VMO, while others do not show delay. It has been suggested that this discrepancies may be due to differences in the signal processing and analysis.
