Stronger Knees, Healthier Hips
Lateral training with Helix® isn’t just safe for knees and hips, it’s actually good for them. In fact, physical therapists routinely use Helix® Lateral Trainers, either in upright or recumbent formats, for clients with knee or hip injuries and to rehabilitate patients after total hip and knee replacement surgeries.

Clinical Data

From The Professionals: Why Helix® Works
Quicker rehabilitation:Helix® is unparalleled in aiding athletes to regain proprioception after injury. Simply put, proprioception is an automated communication mechanism in the body whereby messages are sent to the central nervous system via a network of “communication wires” in the muscles, joints and connective tissues.
Through years of specialized training, elite athletes have dramatically increased numbers of receptors regulating their movements, enabling peak performance. Injury and surgery cut these crucial “communication wires” and rehabilitative metal pins and implants can block their transmission. Rehabilitation must therefore involve, among other things, the re-training of these “wires” to communicate effectively again.
Lateral trainers help to re-teach the body in a safe environment. The player can begin to reconnect these “wires” long before he/she is fit enough to return to the field or the ice. No other machine enables this. The Helix® is truly a breakthrough for many sports.* Source, Dr. Daniel C. Snyder, MD

He is a member of the American Association of Hip and Knee Surgeons (AAHKS). Dr. Snyder is an Assistant Clinical Professor at the Tufts University School of Medicine. He is board certified in Orthopedic Surgery and specializes in total joint replacement and is a leader in the field of hip joint preservation. Dr. Snyder’s practice is currently focused on consulting, teaching, and assisting with anterior hip surgery and hip joint preserving approaches for the treatment of arthritis of the hip.
Knee and Hip Safety
Lateral training allows for safe and therapeutic strengthening of the muscles that support the knees and hips. A non-impact, closed chain exercise,
Helix® Lateral Trainers target the muscles that other cardio largely ignores, such as the gluteus medius, the adductors, and the abductors, thereby strengthening critical support structures for knee and hip joints. It increases mobility and flexibility in the hip joint and it improves balance to reduce fall risk. The result is often less knee and hip pain and better function.
