Lequesne Index - Provides an index of severity for OA of the knee. The Lequesne index is a 10-question interview-style survey given to patients with OA of the knee. It assesses pain or discomfort, maximum distance walked and activities of daily living. The total questionnaire is scored on a 0 to 24 scale, with lower scores indicating less functional impairment.

Gastrointestinal Symptom Rating Scale (GSRS):
The GSRS is a validated disease-specific questionnaire designed to evaluate common GI symptoms. The GSRS comprises 15 symptoms and uses a 7-point Likert scale in which 1 represents the most positive option and 7 the most negative. The items are combined into five clinical syndromes: abdominal pain, gastro-oesophageal reflux, indigestion, diarrhoea and constipation. Using a scoring algorithm, a GSRS total score is calculated
