Brief summary

The present study has examined the effectiveness of extracorporeal shock wave therapy along with conventional physical therapy on functional ability in grade IV knee osteoarthritis. Intervention program was performed for four weeks. Conventional physical therapy included ultrasound therapy, isometric quadriceps, straight leg raising (SLR) and isometric hip adductor strengthening exercises. Functional ability was assessed using the Lower Extremity Functional Scale (LEFS) score.

Interventions

OTHERExtracorporeal Shock Wave Therapy

The ESWT was performed by an ESWT instrument (Chattanooga) once a week for four consecutive weeks (a total of four sessions).

OTHERconventional physical therapy

Conventional physical therapy consisted of ultrasound therapy and three types of knee-strengthening exercises.

Design outcomes

Primary

Measure	Time frame	Description
Lower Extremity Functional Scale (LEFS) score	4 weeks	It is a measurement tool used to assess the functional status and ability of individuals with lower extremity musculoskeletal conditions or injuries. The LEFS consists of 20 items and each item is rated on a scale from 0 to 4, with 0 indicating extreme difficulty to perform the activity and 4 indicating no difficulty at all. The scores for all items are summed to obtain a total score ranging from 0 to 80.
