Calcaneal spur (CS), a prevalent cause of localized heel pain, can significantly impact daily activities by causing discomfort and functional limitations. Symptoms typically include heel pain, especially during walking or after prolonged periods of inactivity, such as getting out of bed in the morning. This study aimed to evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) and high-intensity laser therapy (HILT) in managing calcaneal spur-related symptoms. These non-invasive modalities were compared in terms of their ability to reduce pain and improve functional outcomes.
In this randomized clinical trial, patients diagnosed with calcaneal spur based on clinical and radiographic findings were randomly assigned to receive extracorporeal shock wave therapy (ESWT) or high-intensity laser therapy (HILT). Participants were randomized into 2 groups to receive either ESWT or HILT, complemented by standardized exercise regimens. Pain intensity was measured using the Visual Analog Scale (VAS), and functional outcomes were assessed with the Foot Function Index (FFI) at baseline, post-treatment, and 3 months post-treatment.
Both groups showed significant improvements in pain and functional outcomes. In the ESWT group, VAS scores for initial step pain decreased from 7.8 ± 1.0 to 4.0 ± 1.0 post-treatment and further to 3.4 ± 1.0 at 3 months (P = 0.002). The HILT group demonstrated a similar trend, with scores reducing from 7.5 ± 1.2 to 4.2 ± 1.1 post-treatment and 3.5 ± 0.9 at follow-up (P = 0.001). Total FFI scores improved significantly in both groups, with the ESWT group showing a larger reduction (58.8 to 19.7; P = 0.033) compared to the HILT group (57.4 to 35.4; P = 0.046). No significant adverse events were reported in either group.
ESWT and HILT are effective non-invasive options for treating calcaneal spur with ESWT providing slightly greater functional benefits.
