The purpose of this study was to examine the immediate effect of using a short-term protocol of topical cold spray on ankle joint position sense (AJPS) in healthy individuals. Materials and Methods: Thirty healthy male soccer players with a mean age of 23.2±1.29 years, height 177.11±5.92 cm, weight 69.5. ±6.73 kg, participated in this study. Simultaneously, inside and outside of the ankle was cold by spray. The accuracy of the ankle position sense before and immediately after applying cold was assessed by Electrogoniometer at angles of 10° and 20° dorsi and plantar flexion. Results: The results showed that despite the reduction of AJPS accuracy after using a short-term protocol of local cooling; there was no significant difference between the error of estimated angle before and after cold therapy. Conclusion: It appears that the use of cold spray for a short time only has an immediate effect on the skin receptors. But the muscle spindles and joint receptors as deeper receptors, which have a key role in JPS, are not affected. Keywords: Joint position sense, Ankle joint, Cryotherapy.

... more Purpose: Everything that impairs joint proprioception system can harm joints. It has been stated
that stretching exercises can change properties of the proprioceptive receptors and as a result
changes the sensibility of the joints proprioception. Due to fact that static stretching has greater
use between athletes, it is necessary to give useful information about the safety of these stretching
exercises and their effect on knee joint position sense. Therefore, the purpose of this study was
to determine the effect of static stretching of selected muscles around knee on knee joint position
sense in football players.
Methods: This study was a quasi-experimental research with pretest and posttest design. In this
study, 30 soccer players at the college level, with the mean age of 23.20 ± 1.45 years were
selected through purposeful sampling. Before performing stretching exercises and measuring,
subjects had 5 minutes warm up on a fixed bike with the same speed. Then, knee joint position
sense were measured by electrogoniometer SG150 model and the achieved figures were recorded
as pretest record in the record sheet. Then static stretching exercise protocol was applied on the
selected muscle and immediately after that, joint position sense was measured. The obtained data
were recorded as posttest record. The paired t test was used to compare the mean of pretest to
the posttest mean.
Results: The results of the study showed that there is no significant difference between the mean
of knee joint position sense before doing static stretching exercises and thereafter (P = 0.13).
Conclusion: According to the results of this study, athletes, trainers and coaches can use the
static stretching without fear of negative effects on the proprioception.
