Spasticity is one of the most common and disabling complications of stroke. Most of these patients notably experience both muscle-based and non-muscle-based pain. This negatively affects their quality of life as well as aggravates caregiver burden. Post-stroke spasticity (PSS) may furthermore lead to several complications related to limited mobility, both motor (eg, contractures) and non-motor (cognitive decline, depression) if left untreated. It is thus crucial to address this with safe and effective means such as botulinum toxin therapy as early as possible. We aim to demonstrate the utility of botulinum toxin (BoNT) in PSS treatment and how early intervention may be preferable to late spasticity control for patients. Literature search and evaluation were done using the traditional evidence hierarchy. Early intervention with botulinum toxin A (BoNTA) demonstrated a more marked reduction in both spasticity and spasticity-related pain with longer required intervals to reinjection.

Objective. To determine the efficacy of rTMS in decreasing body mass index (BMI) versus sham stimulation among obese Filipino patients. Methodology. This was a single-center, randomized, sham-controlled, single-blind, parallel group trial. Participants were 15-65 years old with BMI ≥30 kg/m2 and weight stable for 6 weeks. Participants were randomized to receive real rTMS or sham stimulation. Each underwent 4 sessions of stimulation over 2 weeks. Anthropometrics, total caloric intake (TCI), and VAS score for appetite were taken at baseline, 2, 4, 6, and 12 weeks. Results. A total of 31 patients were randomized with 15 to the treatment and 14 to sham stimulation completing treatment, with 2 lost to follow-up. A significant decrease in BMI was noted after 4 weeks from the start of rTMS in the treatment group, (0.6±0.6, p-value=0.001), with weight change of -1.3±1.3 kg (p-value=0.009), but was no longer observed at 6 weeks onwards. No severe adverse effects were noted. Conclusion. rTMS to the DLPFC effectively decreased BMI (0.6±0.6) and weight (-1.3±1.3 kg) from baseline to 4 weeks. At 6-12 weeks after rTMS however, there was no longer a significant difference, indicating that 4 sessions of rTMS may not be enough to produce a prolonged effect on weight loss.
