Knee ROM after traction device removal was 90-100 (92 ± 3) °, an increase of 10-65 (39-14) ° compared with the ROM after arthrolysis (p < 0.05). The follow-up duration was 11-32 (18 ± 6) months. Knee ROM at final follow-up was 80-130 (104 ± 12) °, an increase of 40-100 (68 ± 16) 8° compared with pre-operatively (p < 0.05), and of – 10-40 (12 ± 13) ° compared with the ROM after traction removal (p < 0.05). Knee function was excellent in 14 cases (67%), good in 6 (28%), and fair in one (5%).

The MJ plus patellar traction lengthens the contracted quadriceps femoris, thus restoring knee function within a short period of time.

Due to the importance of bilateral motor actions on activities of daily living, we now examine how bilateral coordination may be differentially affected by right or left hemisphere stroke. To avoid the caveat of simply adding unimanual deficits in assessing bimanual coordination, we designed a unique task that requires spatiotemporal coordination features that do not exist in unimanual movements. Participants with unilateral left (LHD) or right hemisphere damage (RHD) and age-matched controls moved a virtual rectangle (bar) from a midline start position to a midline target. Movement along the long axis of the bar was redundant to the task, such that the bar remained in the center of and parallel to an imaginary line connecting each hand. Thus, to maintain midline position of the bar, movements of one hand closer to or further away from the bar midline required simultaneous, but oppositely directed displacements with the other hand. read more Our findings indicate that left (LHD), but not right (RHD) hemisphere-damaged patients showed poor interlimb coordination, reflected by significantly lower correlations between displacements of each hand along the bar axis. These left hemisphere-specific deficits were only apparent prior to peak velocity, likely reflecting predictive control of interlimb coordination. In contrast, the RHD group bilateral coordination was not significantly different than that of the control group. We conclude that predictive mechanisms that govern bilateral coordination are dependent on left hemisphere mechanisms. These findings indicate that assessment and training in cooperative bimanual tasks should be considered as part of an intervention framework for post-stroke physical rehabilitation.By adopting the extension approaches of Mendelian randomization, we successfully detected and prioritized the potential causal risk factors for BMD traits, which might provide us novel insights for treatment and intervention into bone-related complex traits and diseases.

Osteoporosis (OP) is a common metabolic skeletal disease characterized by reduced bone mineral density (BMD). The identified SNPs for BMD can only explain approximately 10% of the variability, and very few causal factors have been identified so far.

The Mendelian randomization (MR) approach enables us to assess the potential causal effect of a risk factor on the outcome by using genetic IVs. By using extension methods of MR-multivariable MR (mvMR) and MR based on Bayesian model averaging (MR-BMA)-we intend to estimate the causal relationship between fifteen metabolic risk factors for BMD and try to prioritize the most potential causal risk factors for BMD.

Our analysis identified three risk factors T2D, FG, and HCadjBMI for FN BMD; four risk factors FI, T2D, HCadjBMI, and WCadjBMI for FA BMD; and three risk factors FI, T2D, and HDL cholesterol for LS BMD, and all risk factors were causally associated with heel BMD except for triglycerides and WCadjBMI. Consistent with the mvMR results, MR-BMA confirmed those risk factors as top risk factors for each BMD trait individually.

By combining MR approaches, we identified the potential causal risk factors for FN, FA, LS, and heel BMD individually and we also prioritized and ranked the potential causal risk factors for BMD, which might provide us novel insights for treatment and intervention into bone-related complex traits and diseases.

In recent years, several light and laser therapies have been proposed and used in the treatment of NL with variable outcomes. The aim of the study was to investigate the efficacy and safety of lasers and light therapies for the treatment of NL. A review of PubMed was conducted to search for studies using laser and light therapies for the treatment of NL. Articles that employed a combination of treatment modalities were excluded. Twenty-four studies were reviewed. Light and laser therapies used in these studies included CO2 laser, pulsed dye laser, methyl aminolevulinate (MAL)-photodynamic therapy (PDT), aminolevulinic acid (ALA)-PDT, ultraviolet A1 (UVA1) phototherapy, and psoralen plus ultraviolet-A (PUVA). PUVA was identified as the modality with the most available evidence (7 studies), followed by MAL-PDT and ALA-PDT (5 studies each), pulsed dye laser and UVA1 (3 studies each), and lastly CO2 laser (2 studies). Most modalities demonstrated variable efficacies and side effects with the exception of PDL, which consistently showed successful outcomes. Multiple dermatologic light and laser therapies have been investigated for the treatment of NL, including PUVA, ALA-PDT, MAL-PDT, pulsed dye laser, UVA1, and CO2 laser. However, a clear consensus on the preferred treatment is yet to be addressed. Each treatment option demonstrates both advantages and disadvantages that should be discussed with patients when selecting the treatment modality.
