Objectives: To investigate the clinical efficacy of physiotherapy with and without superficial
dry needling on patients with knee pain; patellofemoral pain syndrome.
Methods: A randomized clinical trial conducted in 2015, Tehran, Iran. Of patients with
patellofemoral pain syndrome, thirty-four subjects were randomly divided into two groups (17
in each group). Group A was subjected to physiotherapy and group B to physiotherapy with
superficial dry needling. Only for group B, superficial dry needling was applied during the
ten-day sessions of physiotherapy, every other day. The needle remained for 6 minutes at threepoints
of the quadriceps muscle, accompanied with needle rotation. Both groups received 10
therapy sessions. For both groups, in the first and tenth sessions, knee pain and quadriceps
muscle strength was evaluated.
Results: Statistical analysis showed the two variables in each group had significant
improvements after the 10 sessions (P<0.05). Comparing the two groups, group B showed
more pain reduction based on the visual analog scale (P<0.05). However, according to manual
muscle testing method, the muscle strength between both the groups showed no significant
difference (P<0.156).
Discussion: Physiotherapy with and without superficial dry needling were seen to reduce pain and
increase muscle strength of patients with patellofemoral pain syndrome. However, performing
physiotherapy with superficial dry needling had a more significant effect on reducing knee pain.
Superficial needling can cause many physiological and neurophysiological effects. Through
stimulation of pain control mechanisms, it can help in further reduction of pain.

Discussion: Physiotherapy with and without superficial dry needling were seen to reduce pain and increase muscle strength of patients with patellofemoral pain syndrome.
Generally, any factor that leads to disrup- tion of the extensor mechanism of the knee can reduce muscle strength and change the movement pattern and finally, lead to patellofemoral pain syndrome [1, 3, 6, 8].
According to the statistical results obtained, it can be expressed that routine physio- therapy can lead to significant improvement in both pain and muscle strength after 10 treatment sessions.
According to the statistical results obtained, it can be expressed that routine physiotherapy and superficial DN can lead to significant improvement in both pain and quadriceps muscle strength after treatment for 10 sessions.
Clinical application Based on the results of this study, applying physiothera- py plus superficial DN can be recommended as an appro- priate and more effective treatment strategy to improve the symptoms of patients with patellofemoral pain syndrome.
