A lateral maneuver is any controlled movement where the body shifts sideways rather than forward or backward. In sports, this most commonly refers to cutting, sidestepping, or shuffling, where an athlete plants one foot and pushes off to change direction along the side-to-side (coronal) plane. The term also appears in medicine, where “lateral maneuver” or “lateral approach” describes specific techniques in surgery and childbirth. The sports context is by far the most common reason people encounter the term, so that’s where we’ll start.
How Lateral Movement Differs From Forward Movement
Most everyday movement happens in the sagittal plane: walking, running, jumping straight ahead. A lateral maneuver shifts the primary demand to the coronal plane, the imaginary line that divides your body into front and back halves. When you sidestep to dodge someone on a basketball court or cut laterally on a soccer field, your joints handle forces they rarely encounter during straight-line running.
Research on lateral stepping shows that hip forces in the coronal plane reach 35 to 43 percent of the peak forces generated in the sagittal plane. That may sound modest, but your hip, knee, and ankle aren’t as well-supported in side-to-side motion, which is why lateral maneuvers are a leading cause of lower-body injuries. Lateral step-ups, for example, produce about 8 percent more knee bending, 10.5 percent greater concentric power, and 8 percent more total work at the knee compared to forward step-ups, despite feeling like a similar effort.
Forces Your Body Absorbs During a Cut
When a basketball player plants a foot to cut laterally, the vertical force slamming through that leg can reach roughly two times their body weight. The side-to-side force at the foot hits about 1.5 times body weight. These forces spike in milliseconds, which is why the rate at which force builds (not just its peak) matters so much for injury risk.
Ankle braces and taping change how those forces are distributed. In a study of basketball cutting maneuvers, players wearing a semi-rigid brace experienced significantly lower vertical force during the push-off phase (about 1.44 times body weight versus 2.02 without support) and spread that force over a longer time window. Taping reduced vertical force similarly but actually increased the speed at which side-to-side force peaked, potentially adding stress to the ankle in the inversion/eversion direction. The brace offered the best overall shock absorption during lateral cuts.
Muscles That Power Lateral Maneuvers
Four muscle groups do the heavy lifting during a lateral cut or sidestep. The quadriceps (front of the thigh) and hamstrings (back of the thigh) control forward-backward shear at the knee and protect the ACL from being pulled too far forward. The gluteus medius, the fan-shaped muscle on the outer hip, controls how much the knee collapses inward during the plant foot’s ground contact. The gluteus maximus stabilizes hip rotation so the entire leg stays aligned rather than twisting under load.
Weakness in any of these groups shifts stress onto ligaments instead of muscles. This is why lateral agility training almost always includes hip-strengthening exercises: the glutes are the primary defense against the inward knee collapse that damages the ACL during a hard cut.
Why Lateral Cuts Are Hard on the ACL
The anterior cruciate ligament absorbs the most strain when the knee is relatively straight. Research using in vivo strain measurements found that ACL strain increases as knee flexion decreases, with peak strain occurring when the knee is nearly locked in both the sagittal and coronal planes. Landing or planting on a straight knee during a lateral maneuver puts the ACL at its most vulnerable.
Interestingly, the degree of inward or outward knee angle (valgus or varus) did not independently predict ACL strain in that same study, because very little coronal-plane motion actually occurred at the knee during controlled activity. What matters more is the combination of a straight knee with rotational force, which is exactly what an aggressive lateral cut produces.
A large prospective study of 756 elite female handball and soccer players found that athletes who had previously torn their ACL unconsciously adopted safer mechanics during lateral cutting. They landed with about 1.4 to 1.5 degrees less inward knee angle and generated lower rotational moments at the knee compared to players who had never been injured. They also approached the cut at lower speeds. These subtle adjustments, likely learned through rehabilitation, are considered protective. The takeaway for uninjured athletes: landing with a slightly bent knee and minimizing inward knee collapse during lateral maneuvers reduces ACL risk.
Testing Lateral Agility
Coaches and trainers measure lateral maneuver ability using a few standardized tests. The T-test requires athletes to sprint forward, shuffle laterally in both directions, and backpedal in a T-shaped pattern. It’s a staple assessment in basketball and football programs because it captures front-to-back and side-to-side transitions in a single effort.
The 5-10-5 shuttle, also called the pro-agility test, is used at the NFL combine and in most field and court sports. Athletes start at a center cone, sprint five yards to one side, reverse direction for ten yards, then reverse again for five yards. The setup is simple (three cones, five yards apart), but the test demands explosive lateral deceleration and re-acceleration. The Illinois agility test covers more ground, lasts longer, and includes turns at multiple angles, making it a better measure of sustained directional change rather than pure lateral quickness.
Lateral Maneuvers in Medicine
The term shows up in two notable medical contexts. In orthopedic surgery, a lateral approach refers to accessing a joint from the outer side of the body. During total knee replacement in patients whose knees angle outward (valgus deformity), surgeons use a lateral approach to directly reach and correct the structural problem. This involves releasing tight tissues on the outer knee, rotating the shinbone inward for better access, and preserving the blood supply on the inner side of the joint. The approach allows the surgeon to balance the knee’s soft tissues step by step without disrupting structures that a more common medial approach would compromise.
In obstetrics, the Gaskin maneuver is sometimes called a lateral or positional maneuver for resolving shoulder dystocia, a complication where a baby’s shoulder becomes stuck behind the mother’s pelvic bone during delivery. The mother moves onto her hands and knees, which changes the pelvic geometry enough to free the shoulder. Gentle traction is then applied to guide delivery. This maneuver is reserved for patients who can move freely and aren’t under epidural analgesia.
