Episode Details

MSK Ultrasound and Joint Injection. Part of the Musculoskeletal series of the Reflex PM&R Board Review podcast. Audio correction: In the audio: the timeline to memorize is three to seven days for initial onset, two to four weeks for peak effect, and three to four months for total duration — Correct: The peak is at ~3 WEEKS, not two to four weeks. Botulinum toxin for focal spasticity follows the rule of threes: onset ~3 days (24-72 hours), PEAK EFFECT ~3 WEEKS, duration ~3 months (3-4 months), with re-injection no sooner than every 3 months (12 weeks). Note MSK-25-b states the correct timeline on air (about three days / three weeks / about three months); Part A is the stale half of the pair. The written chapter is correct.
