Physical therapy start-up Sword Health has raised $8 million in new funding firm Khosla Ventures. The U.S. healthcare system spends about $190 billion yearly on physical therapies prescribed to treat muscular and skeletal disorders and this new round of financing is aimed at cutting these costs. Sword Health primarily focuses on five key pathologies — lower back pain, shoulder pain, neck pain and physical therapy in the wake of knee and hip replacement surgeries.

Notable Quotes: “Lower back pain is the most important one in terms of chronic pain, then knee and shoulder pain.” –
Virgilio Bento, Sword Health founder and chief executive

Sword Health raised $4.6 million in seed funding last April. Backing came from Green Innvovations, Vesalius Biocapital and other unnamed investors.
