Abstract:
The purpose of this study was to establish the normal values of tendon reflex in normal Korean adults. Ankle tendon reflex(ATR), patellar tendon reflex(PTR) and medial hamstring tendon reflex (MHTR) responses were recorded in 96 limbs of 48 normal Korean adults by delivering tendon taps with an electric reflex hammer. Latency to the onset of the triggered response, peak to peak amplitude and duration of the wave were measured after several repetitions. Minimum latency and duration of the elicited response were chosen to calculate normal means. Side differences were also evaluated. As amplitude showed a marked interindividual variation and side to side variation, lowest recorded value was selected to represent the lower limit of normal. Mean values of latency, duration and amplitude were 30.27?3.18 msec, 11.05?1.08 msec and 1.98?0.89 mV for ATR, 16.37?1.58 msec, 20.63?1.68 msec and 1.56?0.76 mV for PTR and 20.25?2.14 msec, 10.95?1.57 msec and 0.71?0.56 mV for MHTR. Age, height, and leg length showed significant correlation with the latency of ATR, PTR and MHTR latency(P<0.001). We believe our results can be used as guideline researches in clinical practice.
