Parallel bars provide stable support for gait training, balance exercises, and strength building in physical therapy and gymnastics. Two adjustable-height bars (typically 6-8 ft long, 18-24 inches apart) allow patients to practice walking post-stroke/surgery, perform assisted squats/step-ups, or master transfers from wheelchair to bed with fall protection. Rehab uses include neurological recovery (MS, stroke coordination), weight-bearing for bone density, posture alignment. Fitness applications feature dips, L-sits, leg raises, pull-ups targeting triceps/chest/core. Beginners start with support holds (arms extended, feet grounded) progressing to swing-throughs. Stainless steel/rehab models ensure hygiene/durability; width/height adjusts for pediatric-adult use.
