Detailed Description
The present study is carried out within the project "Physical ActIvity after hip and knee Replacement" (PAIR) and funded within the Erasmus Plus Sport program (Grant Agreement 613008-EPP-1-2019-1-IT-SPO-SCP). It is aimed at evaluating the efficacy and safety of an exercise program specifically designed for improving physical function and QoL in people who had undergone THR or TKR for primary osteoarthritis after completing the surgical and rehabilitative treatment.
The primary objective of the study is to compare modifications of QoL measured with the Short-Form Health Survey (SF-36) induced in the intervention groups (IG) by the PAIR exercise program versus a control groups (CG) who will undergo usual care. SF-36 is one of the most widely used questionnaire to measure the health related QoL (HRQoL) in total hip and total knee arthroplasty patients.
The secondary objectives of the study are to investigate differences between IG and CG on domains which are considered to be determinants of QoL:
Hip- and knee-related impairments and functional limitations
- Harris Hip Score (HHS), American Knee Society scoring (KSS),
- Visual analog scale (VAS) to evaluate pain, High-Activity Arthroplasty Score (HAAS), ---Western Ontario and McMasters Universities Osteoarthritis
- Index (WOMAC),
- Knee Injury and Osteoarthritis Outcome Score (KOOS)
- Hip Disability and Osteoarthritis Score (HOOS).
Hip- and knee-related functional status
- Time Up and GO (TUG),
- Single Stance test,
- The 30-second Chair-Stand Test (30s-CST),
- Hand Grip test, Maximal strength of the lower limb,
- Hip and knee joints mobility (by goniometry).
Life style The ultimate goal of the PAIR exercise program is to increase physical activity in a sedentary population. The exercise program, through its beneficial effects on health, is expected to generate a virtuous circle promoting a more active life-style. For this domain 2 instruments will be used: Recent Physical Activity Questionnaire (RPAQ) and PAIR questionnaire for patients' attitudes toward physical (instrument generated within the PAIR project).
Safety: Adverse clinical events (ACEs) occurred to the participants both inside and outside gym classes.
Adherence: adherence of each subjects to the exercise program will be monitored in the IG. The adherence will be measured as percent of exercise sessions actually performed/total number of scheduled exercise sessions. Other factors considered to influence the adherence to an exercise program will be also recorded (age, gender, comorbidity, BMI, educational level, marital status, working activity, and home gym-distance).
Participants' satisfaction Satisfaction of PAIR exercise program is a very important domain since influence adherence. It will be verified by asking few questions with structured responses based on a 7-point Likert scale, to get participants' opinion about the PAIR exercise program.

Other: INTERVENTION GROUP
The IG will participate in a 6-month exercise program based on the PAIR exercise protocol and will receive educational sessions and material on the importance of maintaining an active life style after THR or TKR
|
The intervention groups will be trained in a gyms under the direct supervision of a graduate trainer.
All subjects will be requested to choose an additional third day of the week to carry out at least one of the following activities: walking, cycling or swimming
|
No Intervention: CONTROL GROUP
The CG will receive only educational sessions and material on the importance of maintaining an active life style after THR or TKR

What is the study measuring?
Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Quality of life questionnaire
Time Frame: 6 months
|
Short-Form Health Survey (SF-36).
SF-36 is one of the most widely used questionnaire to measure the health related quality of life (QoL) items are scored so that a high score defines a more favorable health state.
In addition, each item is scored on a 0 to 100 range so that the lowest and highest possible scores are 0 and 100
