Study summary

The goal of this randomized clinical trial is to evaluate the effects of high-intensity laser therapy on pain intensity, quality of life, hip range of motion, and global rating of change in individuals with femoroacetabular impingement syndrome (FAIS).

The main questions it aims to answer are: Does high-intensity laser therapy improve pain intensity, quality of life, hip range of motion, and global rating of change in patients with Femoroacetabular Impingement Syndrome? Does adding high-intensity laser therapy to exercise therapy produce greater improvements in pain intensity, quality of life, hip range of motion, and global rating of change in patients with Femoroacetabular Impingement Syndrome?

Participants will be randomly assigned to one of two groups for comparison. The first group (control group) will receive a standardized exercise therapy program consistent with routine exercises for femoroacetabular impingement syndrome, along with sham high-intensity laser therapy. The second group (experimental group) will receive the same standardized exercise therapy program in addition to active high-intensity laser therapy.

Read the detailed description

High-intensity laser therapy (HILT) is a non-invasive therapeutic modality that uses high-intensity laser energy to penetrate tissues and promote pain relief and tissue healing. Emerging evidence suggests that HILT may be effective in reducing musculoskeletal pain and improving joint range of motion in individuals with shoulder and knee conditions. However, evidence regarding its effectiveness in individuals with femoroacetabular impingement syndrome (FAIS) remains limited. Thus, the investigators hypothesized that HILT would improve pain intensity, quality of life, hip range of motion, and global rating of change in individuals with FAIS.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adults aged 20-45 years
  • Anterior hip or groin pain with an average intensity of at least 3/10 persisting for a minimum of six weeks
  • Pain aggravated by prolonged sitting or hip movements involving impingement positions
  • Positive flexion, adduction, and internal rotation (FADIR) test
  • Radiographic evidence of cam morphology, with an alpha angle ≥60° in at least one hip

Exclusion criteria

Exclusion Criteria:

  • Physiotherapist-led treatment or intra-articular hip injection within the previous three months
  • Previous hip, pelvic, or spinal surgery
  • Planned lower-limb surgery within the following 12 months
  • Moderate-to-severe hip osteoarthritis (Kellgren-Lawrence grade ≥2)
  • Neurological, systemic arthritic, or other musculoskeletal conditions primarily responsible for hip pain
  • Inability to complete the assessments or commit to the six-month treatment and follow-up period
  • to radiographic imaging
  • Pregnancy at enrollment or during the trial
  • Contraindications to high-intensity laser therapy (HILT), including known or suspected in the treatment area, photosensitivity or use of photosensitizing medications, active deep vein thrombosis, and impaired sensation in the treatment area
  • Inability to comply with laser safety precautions, including the use of protective eyewear
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Pain intensity

    Pain intensity will be measured using the Numeric Pain Rating Scale ( NPRS). Scores range from 0 (no pain) to 10 (worst pain).

    Time frame: Pre-intervention,post intervention (week 6), and week 12 as follow up.

Secondary outcomes

  1. Hip range of motion

    Hip range of motion will be measured using a goniometer , with measurements recorded in degrees.

    Time frame: Pre-intervention,post intervention (week 6), and week 12 as follow up.

  2. Hip-related quality of life

    The hip-related quality of life will be measured using the International Hip Outcome Tool (iHOT-33). Scores range from 0 (worst possible hip-related quality of life) to 100 (best possible hip-related quality of life).

    Time frame: Pre-intervention,post intervention (week 6), and week 12 as follow up.

  3. Perceived rate of change

    The perceived rate of change will be measured using the Global Rating of Change (GROC). Scores range from negative values (worsening) to 0 (no change) and positive values (improvement).

    Time frame: Pre-intervention,post intervention (week 6), and week 12 as follow up.
