Objectives To study the effectiveness of mirror therapy along with a Stroke rehabilitation program on oedema, pain intensity and functional activities in patients with shoulder‐hand syndrome (SHS) after stroke. Design Randomized controlled trial. Settings Out‐patient rehabilitation center. Methods Thirty‐eight SHS patients after stroke, were randomly allocated into two groups; both the groups received a 4‐week stroke rehabilitation program, 30 min a day for 5 days a week. Control group patients performed all the exercises of stroke rehabilitation program, while directly visualizing their both limbs. Experimental group patients performed same exercises of stroke rehabilitation program in front of the mirror. Outcome Measures Oedema (figure‐of‐eight measurement method), pain intensity (0–10 Numeric Pain Rating Scale [0–10 NPRS]), functional activities (Functional Independence Measure [FIM]). Results After intervention, both groups showed statistically significant (p < 0.05) improvement for all measures (oedema measurement, 0–10 NPRS and FIM). Improvements were more significant (p < 0.05) in the experimental group with mirror therapy for all three measures compared to the control group. Mean differences between groups were 1.40 cm for oedema measurement, 0.87 for NPRS score and 12.20 for FIM score. At 2‐week follow‐up, the improvements were sustained. Conclusion The current study may indicate mirror therapy as an effective central neuromodulatory rehabilitative program to reduce pain, improves functional activities. More distinctively, this preliminary study suggests a decrease in oedema by mirror therapy for SHS after stroke. Improvement of upper limb in SHS after stroke will be more perceptible with the decrease in oedema, being the characteristic sign, following mirror therapy. Clinically, patients during their daily functional activities, shall be more confident to use their upper limb following mirror therapy after reduction in oedema along with pain.

Background The global prevalence of obesity has soared to a concerning height in the past few decades. Interestingly, the global decline in semen quality is a parallel occurrence that urges researchers to evaluate if obesity is among the most essential causatives of male infertility or subfertility. Main body Obesity may alter the synchronized working of the reproductive-endocrine milieu, mainly the hypothalamic-pituitary-gonadal (HPG) axis along with its crosstalks with other reproductive hormones. Obesity-mediated impairment in semen parameters may include several intermediate factors, which include physical factors, essentially increased scrotal temperature due to heavy adipose tissue deposits, and systemic inflammation and oxidative stress (OS) initiated by various adipose tissue-derived pro-inflammatory mediators. Obesity, via its multifaceted mechanisms, may modulate sperm genetic and epigenetic conformation, which severely disrupt sperm functions. Paternal obesity reportedly has significant adverse effects upon the outcome of assisted reproductive techniques (ARTs) and the overall health of offspring. Given the complexity of the underlying mechanisms and rapid emergence of new evidence-based hypotheses, the concept of obesity-mediated male infertility needs timely updates and pristine understanding. Conclusions The present review comprehensively explains the possible obesity-mediated mechanisms, especially via physical factors, OS induction, endocrine modulation, immune alterations, and genetic and epigenetic changes, which may culminate in perturbed spermatogenesis, disrupted sperm DNA integrity, compromised sperm functions, and diminished semen quality, leading to impaired male reproductive functions.
