Brief Summary

The purpose of this study is to determine the effect of Biofreeze® versus a placebo on walking gait characteristics and pain during walking in individuals with bilateral knee osteoarthritis (OA).

Conditions

Knee Osteoarthritis

Keywords

Knee Osteoarthritis; Topical Analgesic

Outcome Measures

Primary Outcomes (4)

• Change in Numeric Pain Rating Scale

  Pain will be measures on a scale of 0 to 10, 0 being no pain at all and 10 representing the worst imaginable pain.

  Pain will be measured at baseline, immediately following the 3 minute walk, 15 minutes after topical application, and after the second 3 minute walk for both topical applications

• Change in Knee Flexion

  Knee Flexion Range of Motion will be measured using the Woodway Walker View Treadmill which utilizes a 3D camera and will be measured during the last 30 seconds of the 3 minute walk.

  Knee Flexion Range of Motion will be measured for both topical applications at initial walk and post-topical walk. The session will last a total of 30 minutes.

• Change inHip Flexion

  Hip Flexion Range of Motion will be measured using the Woodway Walker View Treadmill which utilizes a 3D camera and will be measured during the last 30 seconds of the 3 minute walk.

  Knee Flexion Range of Motion will be measured for both topical applications at initial walk and post-topical walk. The session will last a total of 30 minutes

• Change in Step Length

  Step Length will be measured using the Woodway Walker View Treadmill which utilizes load cells within the treadmill belt and will be measured during the last 30 seconds of the 3 minute walk.

  Knee Flexion Range of Motion will be measured for both topical applications at initial walk and post-topical walk. The session will last a total of 30 minutes

Study Arms (2)

Biofreeze

EXPERIMENTAL

The Biofreeze® gel will contain 3.5% menthol while the placebo will be the same formula with menthol removed and a menthol fragrance added so it is non-distinguishable from the real Biofreeze® gel. The dose of both gels will be 5 mL per knee, which is consistent with previous studies who reported a treatment effect for topical gels containing menthol (1 mL of gel for every 200 cm2 of surface area). The treatment will be applied by the investigator using a gloved hand and syringe containing 5mL of gel. The gel will be applied to the anterior and posterior knee from superior patella to the quadriceps insertion over a period of 5 seconds. The participant will wait 15 minutes, rate the pain in their knees.

Drug: Placebo

Interventions

Biofreeze DRUG

Biofreeze is a topical analgesic that uses the cooling effect of menthol, a natural pain reliever, to soothe minor muscle and joint pain. The product will be applied immediately after walking. The participant will wait 15 minutes prior to walking again.

Biofreeze

Placebo DRUG

The placebo is the Biofreeze product with all active ingredients removed. The product will be applied immediately after walking. The participant will wait 15 minutes prior to walking again.

Placebo
