Abstract
Abstract
Objective To evaluate foot function and prevalence of tarsal tunnel
syndrome in patients diagnosed with fibromyalgia syndrome as compared with
healthy individuals.
Methods This prospective study included 111 participants, including 63
female patients with fibromyalgia (mean age: 46.17±6.64 years) and 48
female healthy controls (mean age: 46.16±9.38 years) who met the
selection criteria. The participants were evaluated for Tinel’s sign and
asked about the presence of foot pain and paraesthesia in both groups. In
addition, the participants were assessed using the Fibromyalgia Impact
Questionnaire and Foot Function Index (FFI) for functionality. Bilateral
electrophysiological studies of the tibial, peroneal, sural, medial and lateral
plantar nerves were performed.
Results Tarsal tunnel syndrome was present in 20 extremities of the
patients with fibromyalgia (15.9%) and four extremities of the controls
(4.2%)(p=0.005). Paraesthesia was observed in 56 extremities in
the fibromyalgia group (44.4%) and 10 extremities in the control group
(10.4%)(p<0.001). Tinel’s sign was positive in 69
extremities (54.8%) in the fibromyalgia group and 17 in the control
group (17.7%)(p<0.001). The total number of painful feet was 123
(97.6%) in the fibromyalgia group and 22 (22.9%) in the control
group (p<0.001). The mean total FFI was 66.26±60.80 for the
right foot and 66.28±64.12 for the left foot in the FMS group; in the
control group, it was 16.02±31.01 and 16.87±34.14, respectively.
Both values exhibited a statistically significant difference between the two
groups (p<0.001)
Conclusion In patients with fibromyalgia syndrome, paraesthesia and foot
pain may be seen more frequently. Therefore, electrophysiological evaluation of
the lower extremities may be recommended in these patients.
