Effectiveness of LASER Therapy and PNF Technique in Neck Pain

27. april 2026 opdateret af: Istanbul Gedik University

Low-Intensity Laser Therapy Versus Proprioceptive Neuromuscular Facilitation for Pain and Disability in Chronic Non-Specific Neck Pain: A Randomized Controlled Trial

This study aimed to investigate and compare the effects of low-intensity laser therapy, a photobiomodulation treatment, and proprioceptive neuromuscular facilitation on pain and disability in individuals with non-specific neck pain. This randomized controlled trial used the Numerical Pain Scale (primary outcome) and the Bournemouth Neck Pain Questionnaire to assess pain, a manual algometer to assess pain threshold, and the Neck Disability Index to assess disability. Three groups were included in this randomized controlled trial: Group 1: Photobiomodulation therapy (low-intensity laser therapy) + conventional physiotherapy; Group 2: Proprioceptive neuromuscular facilitation with stretching and strengthening + conventional physiotherapy; Group 3: Conventional physiotherapy only. We hypothesized that low-intensity laser therapy and proprioceptive neuromuscular facilitation would have distinct effects on pain and disability in chronic non-specific neck pain.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Low-intensity Laser Therapy Group
Low-intensity Laser Therapy + Conventional Physiotherapy
Enhed: Low-intensity Laser Therapy Treatment
Low-dose laser therapy was administered twice a week for a total of 10 sessions using a Chattanoga Advance device, at a power of 100 mW and an energy dose of 4 J/cm², with each trigger point receiving treatment plus four additional points marked with a cross (Legouté et al. 2019).
Andre navne:
  • Laserterapi på lavt niveau
  • Fotobiomodulationsterapi
  • Low-dose laser therapy
Andet: Conventional physiotherapy
Conventional physiotherapy involved traditional heat therapy, pain-relieving electrical stimulation and neck exercises.
Eksperimentel: Proprioceptive Neuromuscular Facilitation Group
Proprioceptive Neuromuscular Facilitation Technique + + Conventional Physiotherapy
Andet: Conventional physiotherapy
Conventional physiotherapy involved traditional heat therapy, pain-relieving electrical stimulation and neck exercises.
Andet: Proprioceptive Neuromuscular Facilitation Technique
Stretching and strengthening exercises were performed twice a week for a total of 10 sessions on the scalene, sternocleidomastoid, trapezius, pectoralis major, pectoralis minor, intercostal and serratus anterior muscles, and three times a week for 10 minutes (including the neck extensors). The specific method involved the 'hold-release' technique for 10 repetitions of PNF stretching and the maximum isometric contraction technique for strengthening (Liu et al. 2021; Cruz-Montecinos et al. 2017).

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Numerical Pain Scale
Tidsramme: at baseline and week 5
It was used to assess neck pain. Pain is assessed using a rating scale of 1-10. Higher scores indicate more severe pain.
at baseline and week 5

Sekundære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Pressure-Pain Threshold Measurement
Tidsramme: at baseline and week 5
A manual algometer was used to assess the pain threshold. The pain threshold increases as the amount of pressure applied increases in kilograms.
at baseline and week 5
The Neck Bournemouth Questionnaire
Tidsramme: at baseline and week 5
The study was used to assess the severity of neck pain, functional limitations, and biopsychosocial factors. This indicates that neck pain has a greater impact on the person's life (high level of limitation/pain).
at baseline and week 5
The Neck Disability Index
Tidsramme: at baseline and week 5
It was used to examine disability. An increase in the score means an increase in disability.
at baseline and week 5
