Not Applicable
Completed
Conditions
Osteoarthritis, Knee
Interventions
Dietary Supplement: Maltodextrin (Placebo)
Behavioral: Exercise
Dietary Supplement: Inulin Fibre supplement
Registration Number
NCT05670314
Lead Sponsor
University of Nottingham
Brief Summary

This pilot study will be a placebo controlled randomised intervention study in which participants with knee pain will be grouped into the diet intervention, exercise intervention, diet and exercise intervention or placebo arm. The study involves intake of dietary supplements and performing routine exercises which are commonly used and are not pharmacological agents. The end-points of the study are non-clinical outcomes. N= 120. 2x2 intervention with 30 individuals per block: placebo, diet only, exercise only, diet + exercise

Arm && Interventions
GroupInterventionDescription
Placebo armMaltodextrin (Placebo)The participants in the placebo/control arm (N=30) will be required to take 10g of maltodextrin for the same period of 6 weeks.
Exercise only armExerciseJoint Academy An app-based exercises platform (Joint Academy®) will be used as an intervention given to the treatment arm. The programme consists of a mixture of open and close chain exercises, a combination of concentric, eccentric and focusing on the global strength of legs including the muscles around the hips and knee joints as well as balance enhancement exercises. The intervention also includes educational sessions integrated into the programme covering the basics of OA, its treatment, self-managing symptoms of OA and the benefits of maintaining a healthy lifestyle. The exercise intervention focuses on core stability and performance, neuromuscular leg strengthening and balance enhancement.
Diet + exercise intervention armInulin Fibre supplementThe participants in this arm will be required to take 20g of inulin (N=30) for a period of 6 weeks and doing exercise at the same time.
Diet only ArmInulin Fibre supplementThe participants in the dietary intervention arm will be required to take 20g of inulin (N=30) for a period of 6 weeks.
Diet + exercise intervention armExerciseThe participants in this arm will be required to take 20g of inulin (N=30) for a period of 6 weeks and doing exercise at the same time.
Primary Outcome Measures
NameTimeMethod
Change in Numerical Rate Score (NRS) for painBaseline and 6 weeks

The Numerical Rate Score (NRS) will be used to assess the changes in the level of pain in response to the intervention between baseline and follow-up.

Secondary Outcome Measures
NameTimeMethod
Changes in serum Cytokines levelsBaseline and 6 weeks

Serum levels of cytokines will be measured using ELISA in samples collected at baseline and at follow-up (at the end of six weeks). This will help us ascertain the change in levels of pro and anti-inflammatory cytokines in response to the intervention.

Changes in serum Endocannabinoid levelsBaseline and 6 weeks

Serum levels of Endocannabinoids will be measured using mass spectrometry in samples collected at baseline and at follow-up (at the end of six weeks). This will help us ascertain the change in levels of Endocannabinoids in response to the intervention.

Changes in DNA methylation on a subset of individualsBaseline and 6 weeks

DNA methylation will be measured using specialized ELISA kits in samples collected at baseline and at follow-up (at the end of six weeks).

Changes in serum markers of immune phenotyping (PBMCs)Baseline and 6 weeks

Serum levels of PBMCs will be measured using a multiplex technique in samples collected at baseline and at follow-up (at the end of six weeks). This will help us ascertain the change in immunological function in response to the intervention.

Changes in gut microbiome composition and short chain fatty acidsBaseline and 6 weeks

Changes in gut microbiome composition and serum levels of short-chain fatty acids (SCFAs) in response to the interventions. Gut microbiome composition will be measured using 16S sequencing on stool samples. SCFAs in serum will be measured using mass spectrometry.
