High-Intensity Laser Acupuncture for Treating Patellofemoral Pain Syndrome: Impact on Pain, Function, and Patient Satisfaction

Patellofemoral pain syndrome (PFPS) is among the most prevalent forms of knee discomfort. The main complaint is typically anterior knee pain, which gets worse while jumping, bending knee, going up or down stairs, or sitting for long periods of time with bent knee. Teens and early adulthood are commonly affected by patellofemoral pain syndrome, with a higher frequency in females. In healthy general populations, the prevalence of patellofemoral pain syndrome is 22.7%, and in teens, it is 28.9%.

Detaljeret beskrivelse

Patellofemoral pain syndrome (PFPS) is a common cause of anterior knee pain that limits activities such as stair climbing, squatting, running, and prolonged sitting, leading to reduced function and participation (Crossley et al., 2016; Gaitonde et al., 2019). Exercise therapy is considered a key conservative treatment, especially combined hip and knee exercises, but additional non-invasive modalities may help improve pain relief and recovery (Collins et al., 2018). Laser acupuncture provides non-invasive stimulation of acupuncture points and may offer analgesic and functional benefits without needle insertion. Recent studies suggest that laser acupuncture and high-intensity laser therapy may improve pain and function in patients with PFPS (Ozlu et al., 2024). Therefore, this study aims to evaluate the effect of high-intensity laser acupuncture on pain, knee function, and patient satisfaction in patients with PFPS.

Foranstaltningsbeskrivelse
Tidsramme
Pain Intensity
Tidsramme: 4 weeks
The visual analogue scale represents the pain range that a patient thinks they might experience. The line is typically 10 centimetres long, with or without markings at each centimetre serves as a representation of the range. The worst pain the patient could possibly envision is represented by one end, while; no pain; is represented by the other. The patient marks the scale by drawing a line on it to indicate the amount of discomfort they are experiencing from 0-10. Higher scores represent worse pain.

Foranstaltningsbeskrivelse
Tidsramme
Funktion af knæleddet
Tidsramme: 4 uger
En skala kendt som Kujala patellofemoral score vil blive brugt til vurdering af funktionen af ​​det patellofemorale smertesyndrom. Scoren for dette ratingsystem varierer fra 100 (et normalt, smertefrit, fuldstændig funktionelt knæ) til 0 (alvorlige smerter og dysfunktion i knæet). Haddad et al. udført forskning i validiteten og pålideligheden af ​​den arabiske version af skalaen. Jo større score, jo bedre resultater.
4 uger
patient Satisfaction
Tidsramme: 4 weeks
The satisfaction VAS will be used to measure patient satisfaction. The patient will be by placing an indicator at 0 to100 milliliters line. Zero usually represents 'no satisfaction at all' whereas the upper limit represents 'the best satisfaction ever'.
