Efficacy of a Dietary Ingredient Combination With Omega-3 for Joint Function

Not Applicable
Completed
Conditions
Joint Function Disorder
Interventions
Other: Control product consumption
Dietary Supplement: Omega-3 and/or botanical ingredient
Registration Number
NCT05279573
Lead Sponsor
Universidad Católica San Antonio de Murcia
Brief Summary

Randomized, controlled, double-blind intervention study of four parallel branches depending on the product consumed, to analyze the efficacy of an Omega-3 based product on the mobility and functionality of the evaluated joint.

Detailed Description

The duration of the study will be 60 days (8 weeks). Each day they will have to consume the product under investigation. Subjects who meet the selection criteria will be randomized into each of the study groups (A, B, C o D, depending on the group in which they have been randomized). Each day the subjects will have to fill in a diary regarding pain and concomitant medication.

They will make a total of two visits to the research laboratory and will perform the tests pre-established in the protocol. In addition, a follow-up telephone call will be made after 30 days of consume. Subsequently, a statistical analysis will be performed with the variables measured in the study to obtain the results.

Primary Outcome Measures
NameTimeMethod
Change in Pain from baseline at 8 weeksThe evolution of pain after consumption during 8 weeks will be measured.

Visual analog scale from 0 to 10. The higher the value, the more pain.

Quality of life test: WOMAC testChange in initial quality of life at 8 weeks.

The quality of life of the subjects will be measured with the WOMAC test. It is a 24-item test that will measure the degree of pain: nothing, little, enough and a lot, when performing activities in daily life.

Secondary Outcome Measures
NameTimeMethod
Body compositionThe test will be measured at baseline and after 8 weeks of consumption.

It is a control variable. Measured by bioimpedance

Functional testThe test will be measured at baseline and after 8 weeks of consumption.

The balance and mobility of the subjects will be measured with the Timed Up and Go Test

Sleep qualityIt will be measured twice, once at baseline or at the end of the study after 8 weeks of use

Measured by Pittsburgh test

Sleep efficiencyThe test will be measured at baseline and after 8 weeks of consumption. It will be measured during 3 weekdays and one weekend day.

Measured by accelerometry, with Actigraph wGT3X-BT

Physical activityThe test will be measured at baseline and after 8 weeks of consumption. It will be measured during 3 weekdays and one weekend day.

It is a control variable. Measured by accelerometry, with Actigraph wGT3X-BT

Physical activity controlThe test will be measured at baseline and after 8 weeks of consumption.

It is a control variable. Measured by fitbit

Change in Pain from baseline at 8 weeksPain will be measured with a daily scale, from baseline to 8 weeks.

Visual analog scale from 0 to 10. The higher the value, the more pain.

Change in concomitant analgesic medicationThe test will be measured at baseline and after 8 weeks of consumption. It will also be evaluated on a daily basis

The change in the need for the use of analgesic medications will be evaluated

Liver safety variablesIt will be measured twice, once at baseline or at the end of the study after 8 weeks.

It is a blood test that measures the presence of some enzymes, proteins and bilirubin in the blood, with the aim of determining if there is any alteration in the liver. Enzyme GPT, GOT, Gamma GT, LDH, alkaline phosphatase and bilirubin (UI/L)

Waist - hip circumferenceThe test will be measured at baseline and after 8 weeks of consumption.

It is a control variable.

Muscle functionThe test will be measured at baseline and after 8 weeks of consumption.

Isokinetic and isometric dynamometry

Omega-3 BioavailabilityIt will be measured twice, once at baseline or at the end of the study after 8 weeks.

Measured by omega quant
