Brief Summary

The purposes of this study are:

1. 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. 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.

Conditions

Jumper's Knee

Keywords

Polarized Polychromatic Non Coherent Light (Bioptron)

Outcome Measures

Primary Outcomes (4)

• Pain (Visual analogue scale).

  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.

  Visual analogue scale will be investigated at baseline and after the treatment period of 4 weeks.

• pain intensity (Pressure algometry)

  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.

  Pressure algometry will be investigated at baseline and after the treatment period of 4 weeks.

• Disability questionnaire (Victorian institute of sport assessment-patella).

  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.

  The VISA-P questionnaire will be investigated at baseline and after the treatment period of 4 weeks.

• Muscle strength (Hand held dynamometer)

  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.

  The Lafayette hand held dynamometer will be investigated at baseline and after the treatment period of 4 weeks.

Other Outcomes (1)

• Muscle strength and endurance ( Biodex-Isokinetic Dynamometer)

  The Isokinetic dynamometer will be investigated at baseline and after the treatment period of 4 weeks.

Study Arms (3)

Group A

EXPERIMENTAL

the patients will receive green filter of bioptron light therapy and conventional treatment((ice application+ exercise program)) for jumper knee three times a week for four weeks.

Device: Bioptron

Group B

EXPERIMENTAL

the patients will receive yellow filter of bioptron light therapy and conventional treatment for jumper knee three times a week for four weeks.

Device: Bioptron

Control group

PLACEBO COMPARATOR

the patients will receive conventional treatment (ice application+ exercise program) for jumper knee three times a week for four weeks.

Other: Placebo Comparator

Interventions

Bioptron DEVICE

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.

Also known as: Polarized Polychromatic Non-Coherent Light, Hyperlight

Group A; Group B

Placebo Comparator OTHER

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

Control group
