Objective: To evaluate whether the electrodiagnostical posterior tibial reflex (PTR) will play an adjuvant role in diagnosis of L5 radiculopathy. Methods: Fourteen L5 radiculopathy patients confirmed by routine electrodiagnostic study and age- and sex-matched 14 healthy controls were participated in this study. By using patellar hammer, latencies of PTR were evoked in both legs of each group. Average of 5 repeated PTR latencies were calculated and the difference of the PTR latencies between right and left leg (PTR-D) were compared between two groups. Receiver operating characteristic (ROC) curve was used to determine optimal cut off values of PTR-D in diagnosing L5 radiculopathy. Results: Mean PTR latency in affected legs showed significantly longer value than that in unaffected legs in unilateral L5 radiculopathy group (p<0.05). And, mean value of PTR-D in L5 radiculopathy group was significantly greater than that in control group (p<0.05). PTR-D threshold of 10.0 ms yielded the greatest sensitivity (93%) and specificity (93%) for the diagnosis of L5 radiculopathy. Conclusion: As the PTR latency represented large inter-individual differences, the PTR-D can be used as an optimal parameter for the inter-individual comparison. Furthermore, PTR-D with 10.0 ms threshold gives best diagnostic discrimination for the diagnosis of L5 radiculopathy.

The purpose of this study was to evaluate the analgesic effect of micro-TENS (Magicpulse) in patients with acute and chronic pain. We divided the pain of the subjects into two groups, such as acute pain(pain duration less than 3 months) and chronic pain(more than 3 months), and the analgesic effect was measured by VAS(Visual Analogue Scale) difference, VAS improvement ratio and thermographic change between pre-treatment and post-treatment. As a result, VAS difference was 4.59 ±2.75 in acute pain group and 4.00 ±1.96 in chronic pain group(p<0.01, respectively), and the patients with VAS improvement ratio(>50%) were 62.4% in acute pain group, 46.6% in chronic pain group. A significant increase in skin temperature was observed after treatment(p<0.05). We concluded that the micro-TENS has an analgesic effect on both acute and chronic pain, and the better effect is expected in acute pain than chronic pain.

Heterotopic ossification is frequent complication in patients with spinal cord or brain injury, although the etiology is unknown. The extensive heterotopic ossification is a cause of limitation of active or passive joint motion and ultimately bony ankylosis which interferes independency in activities of daily living and ability of maximum rehabilitation. Whereas, the articular complication of heterotopic ossification have been well documented, the vascular complication are less well known. We experienced one case with vascular compression and obstruction by heterotopic ossification in a patient with traumatic brain injury and reported the case with clinical and radiologcal and laboratoric findings.
