Background: Diabetic neuropathy may be associated with nerve compression neuropathies including tarsal tunnel syndrome (TTS). Low levels laser treatment (LLLT) is a suggested treatment. The present study investigated the effect of LLLT on the clinical and neurophysiological parameters in diabetic patients with TTS.
Method and Materials: Thirty diabetic patients had TTS aged 40-60 years received LLLT. Neurophysiological parameters and visual analog scale were measured before and 12 weeks after of LLLT.
Results: Comparison between pre and post-treatment outcome parameters revealed significant improvement of all parameters including VAS (8.5 ± 1.2 versus 4.6 ± 1.7, p<0.001), motor distal latency (6.7 ± 0.9 versus 5.1 ± 0.9 ms, p<0.001), sensory peak distal latency (4.6 ± 0.5 versus 3.2 ± 0.3 ms, p<0.001), motor amplitude (2.6 ± 0.6 versus 4.1 ± 0.5 mV, p<0.001), medial planter amplitude (6.1 ± 3.2 versus 15.1 ± 3.5 mV, p<0.001) and medial planter amplitude (4.3 ± 2.0 versus 12.5 ± 1.6 mV, p<0.001)
Conclusion: LLLT has positive impact on clinical and neurophysiological parameters in diabetic patients with TTS.
