Anterior cruciate ligament injuries among wakeboarders: a case report.

No previous cases of anterior cruciate ligament (ACL) injuries sustained during wake-boarding have been reported. We report on a case involving an ACL injury sustained during wakeboarding. A 27-year-old man sustained an injury while attempting a wakeboarding maneuver(a heel-side back roll, consisting of a jump and simultaneous roll toward the heel side).

Research on the effectiveness of intermittent cervical traction therapy, using short-latency somatosensory evoked potentials.

Short-latency somatosensory evoked potentials (SSEPs) were measured before and after intermittent cervical traction therapy to serve as objective indicators of therapy effectiveness. The subjects were 29 patients with myelopathy, 23 with cervical radiculopathy, 28 with cervical sprain, and 26 healthy individuals. SSEPs were recorded by stimulating the median nerve, and the negative potentials elicited from the brachial plexus (N9), neck (N11, lcN13, ucN13), and somatosensory area (N18) were measured to determine interpeak latencies and then corrected latency.
