Joint protection apparel protects a workers' neck, back, wrists, elbows, knees and ankles. They are worn in strenuous work environments that can aggravate preexisting injuries or cause muscle strain or joint sprains. Back support belts wrap around a worker’s midsection and provide support in lifting applications. Knee pads slide over or strap onto knees to protect the kneecap. They are designed to resist abrasion, punctures and cuts.
