November 17, 2025 updated by: University of Lahore

Therapeutic Low Laser Therapy and Kinesio Taping in Patients With Grade 1 and Grade 2 Lateral Ankle Sprain

HYPOTHESIS

Null Hypothesis (H0):

There is no significant effect of therapeutic low laser therapy and kinesio taping in patients with grade 1 & 2 lateral ankle sprain.

Alternative Hypothesis (HA):

There is a significant effect of therapeutic low laser therapy and kinesio taping in patients with grade 1 & 2 lateral ankle sprain.

Low-Level Laser Therapy (LLLT) Treatment

  • General Principles of LLLT for Ankle Sprains
  • Purpose: LLLT is used to improve circulation, lessen pain and inflammation, and promote tissue repair.

  • Mechanism of Action: By promoting mitochondrial activity, LLLT raises the synthesis of collagen and ATP. By releasing endorphins and increasing nitric oxide, it improves circulation, lowers inflammation, and regulates pain.

    2. LLLT parameters for lateral ankle sprains in grades 1 and 2 (initial step)

  • Wavelength: For deeper tissue penetration (targeting

    2. Kinesio Taping Application (Second Step) Kinesio taping is performed to support and stabilize the area of injury. By reducing discomfort and swelling, it may enhance comfort during activities.

For Grade 1 Sprains (Mild Injury) Technique:

  1. Y-Strip for Lateral Ankle Sprain: Place the tape at the base of the fifth metatarsal, or the dorsum of the foot.
  2. Wrap Around the Lateral Ankle: Wrap the two Y-shape tails around the lateral ankle,
Active Comparator: Group B
Other: Using Low-Level Laser Therapy

  1. Initial Assessment:

    Comprehensive evaluation is necessary to ascertain the degree of ankle sprain (Grade 1 or Grade 2), range of motion, discomfort, swelling, and functional restrictions at the beginning of treatment.

    • Grade 1 Sprain: Minimal swelling, mild ligament stretching, and no significant impairment of function.
    • Grade 2 Sprain: Moderate swelling, pain while bearing weight, reduced range of motion, and partial ligament treatment

  2. Low-Level Laser Therapy (LLLT) Treatment

    • General Principles of LLLT for Ankle Sprains Purpose: LLLT is used to improve circulation, lessen pain and inflammation, and promote tissue repair.

Mechanism of Action: By promoting mitochondrial activity, LLLT raises the synthesis of collagen and ATP. By releasing endorphins and increasing nitric oxide, it improves circulation, lowers inflammation, and regulates pain.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Foot and Ankle Disability Index
Time Frame: Baseline and at 12 weeks
The 34-item Foot and Ankle Disability Index is broken down into two subscales: the Foot and Ankle Disability Index and the Foot and Ankle Disability Index Sport. FADI has 26 items, whereas FADI Sport has only 8 items. FADI consists of 4 items dealing with pain and 22 items dealing with activities. 8 items in FADI-Sport are activity related. It tests more complex aspects that are crucial to sports. In contrast to FADI, FADI Sport is a subscale derived from the original population scale and specifically tailored for athletes. It is designed to fill this need by identifying the lower-functioning subjects in terms of the higher functions
Baseline and at 12 weeks
Numeric Pain Rating Scale (NPRS)
Time Frame: Baseline and at 12 weeks
An outcome measure that provides a unidimensional gauge of pain intensity in adults. A respondent chooses an integer between 0 (no pain) and 10 (worst possible pain). Higher scores indicate greater pain severity.
Baseline and at 12 weeks
RANGE OF MOTION
Time Frame: Baseline and at 12 weeks
Range of Motion is the maximum movement a joint can achieve, assessed through active (AROM) and passive (PROM) methods, typically measured in degrees using a goniometer. Higher values indicate greater mobility.
Baseline and at 12 weeks
