Abstract
Objectives: Knowledge about gender differences in intra-limb coordination during walking provides insight into the adaptability of central nervous system for controlling gait in older adults. We assessed the variability and phase dynamic of the intra-limb coordination in older men and women during walking.
Methods: Twenty two older people, 11 female and 11 male, participated in this study. They were asked to perform walk on a treadmill at their preferred speed. Deviation phase and mean absolute relative phase values-indicators of variability and phase dynamic of intra-limb coordination, respectively-were calculated using the data collected by a motion capture system. We used independent sample t-test for statistical analysis.
Results: The results showed that women had a significant higher deviation phase in pelvis-thigh inter-segmental relationships on both sides. Additionally, the mean absolute relative phase of left pelvis-thigh, thigh-shank and shank-foot were significantly different between men and women.
Discussion: While women showed a lower mean absolute relative phase in pelvis-thigh, men had a lower mean absolute relative phase in shank-thigh inter-segmental relationships. We suggest that gender could affect the intra-limb coordination variability and phase dynamic during walking in older people. This may be a reflection of the great adaptability of neuromuscular system to modify control strategies for walking in older women/men.

Abstract
Objectives: Dry Needling (DN) is a novel and effective intervention for patients with Myofascial Pain Syndrome (MPS). Some characteristics, such as needle penetration depth, needle insertion into the target muscle, and trigger points must be identified in this intervention. The Ultrasound (US)-guided DN is a technique that involves needle insertion at the site of injury and the simulation of tissue injury and inflammation under US guidance; it indicates the needle insertion site to ensure that it does not penetrate the adjacent tissues. The current study aimed to review previous studies regarding the effects of US-guided DN on MPS.
Methods: A search was performed in PubMed, Scopus, Cochrane, Google Scholar, Springer, and Science Direct databases to retrieve studies published from 2010 to March 2020. We included investigations regarding the effects of US-guided DN on the treatment of MPS. The following keywords and MeSH terms were used in the search process: “ultrasound-guided, musculoskeletal ultrasonography, myofascial pain syndrome, trigger points, and dry needling.”
Results: A total of 47 relevant articles were retrieved. However, based on the inclusion and exclusion criteria of the review, 11 articles were finally selected. All studies reported significant pain relief following the use of US-guided DN in patients with MPS.
Discussion: Considering the precise visualization of the site of muscle involvement, precise needle insertion, and reduction of the risk of further injury in US-guided DN may be a useful approach for MPS management in short-term and long-term studies.
