Effect of Two Different Modes of Polarized Polychromatic Non-coherent Light Therapy on Jumper's Knee

Condition(s) studied

Investigational drug(s) / intervention(s)

Bioptron: Bioptron safely treats arthritis, neck \& back pain by stimulating blood circulation, reducing inflammation and relieving muscle spasms. For just ten minutes per day, our life-transforming technology offers the highest levels of pain relief by reaching deep into joints, muscles and ligaments.

Placebo Comparator: Patients will receive ice application+Exercises program designed for jumper knee

Study summary

The purposes of this study are:

1. To examine the combined effects of Yellow CPPNLT and conventional treatment on pain intensity, pain pressure threshold, functional disability, and muscle strength in athletic jumper knee.
2. To examine the combined effects of Green CPPNLT and conventional treatment on pain intensity, pain pressure threshold, functional disability, and muscle strength in athletic jumper knee.

3 3- To compare between the effects of Yellow CPPNLT and Green CPPNLT on pain intensity, pain pressure threshold, functional disability, and muscle strength in athletic jumper knee.

Eligibility

Primary outcome measure(s)

• Pain (Visual analogue scale). — Visual analogue scale will be investigated at baseline and after the treatment period of 4 weeks.
  The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. The VAS score for grading of pain consists of a 10 centimeters (cm) line with 10 mm (0.01 cm) to each point of the scale and two end-points representing no pain and worst possible pain.
• pain intensity (Pressure algometry) — Pressure algometry will be investigated at baseline and after the treatment period of 4 weeks.
  Pressure pain threshold will be measured with algometry test FPX25 using 1-cm2 rubber tip on the knee extensors.10, 11 pressures will be applied slowly until the participant first feels the pain and response by saying stop there.
• Disability questionnaire (Victorian institute of sport assessment-patella). — The VISA-P questionnaire will be investigated at baseline and after the treatment period of 4 weeks.
  The VISA-P, formerly known as the Victorian institute of sport assessment -patella Questionnaire, The VISA-P is questionnaire that assesses symptoms, simple tests of function, and the ability to play sports.
• Muscle strength (Lafayette Hand held dynamometer) — The Lafayette hand held dynamometer will be investigated at baseline and after the treatment period of 4 weeks.
  The subjects will be positioned in sitting on chair and we will apply resistance when performing the dynamometer on patients and they will try to make maximal effort against resistance and we will record the change of length or resistance.
