The study was designed to evaluate the effectiveness of a novel kinematic biofeedback system - SWORD Phoenix- in the rehabilitation after total hip replacement . SWORD Phoenix allows the patients to perform independent rehabilitation sessions at home, under remote monitoring from the clinical team. The investigators hypothesise that the clinical outcomes of a home-based rehabilitation program will be at least similar to the outcomes of a traditional home-based rehabilitation with face-to-face sessions. This is a randomised controlled trial with active comparator. Patients will be enrolled and allocated pre-operatively into 2 groups: intervention group and control group. Both groups will perform 8 weeks of rehabilitation starting on day 7 after surgery. The intervention group will perform daily rehabilitation sessions at home using SWORD Phoenix, under remote monitoring from a physical therapist. The control group will perform 1h rehabilitation sessions 3 times a week, at home, given by a physical therapist. Outcomes will be measured at weeks 4 and 8. The primary outcome is the performance in the Timed-up-and-Go (TUG) test between in each patient in comparison with the pre-operative score. Secondary outcomes will be measured in terms of: a) range of motion of the hip joint (flexion/extension/abduction/adduction/internal and external rotation); b) Hip Osteoarthritis Outcome Score; c) quality of life, as measured by the SF-36 scale.

Further study details as provided by Sword Health, SA:

Primary Outcome Measures:
  • Change in the Timed Up and Go Test score [ Time Frame: Baseline; 4 weeks after surgery; 8 weeks after surgery ]
    The timed up and go requires a patient to rise from a chair walk three meters around a piece of tape and return to the chair again as quickly as possible.

Secondary Outcome Measures:
  • Change in Hip injury and Osteoarthritis Outcome Score (KOOS) [ Time Frame: Baseline; 4 weeks after surgery; 8 weeks after surgery ]
    The HOOS is a standardized and validated patient outcome score that assesses functional limitation in patients with hip problems.

  • Change in the Short Form-36 Health Questionnaire (SF-36) [ Time Frame: Baseline; 4 weeks after surgery; 8 weeks after surgery ]
    The SF-36 is a widely used quality of life questionnaire

  • Change in the Range of Motion (degrees) [ Time Frame: Baseline; 4 weeks after surgery; 8 weeks after surgery ]
    Change in the hip range of motion (Flexion/extension/abduction/external and internal rotation) measured in degrees

Estimated Enrollment: 54

Arms Assigned Interventions
Experimental: Rehabilitation using SWORD Phoenix
Home-based rehabilitation sessions performed with SWORD Phoenix.
Device: SWORD Phoenix

SWORD Phoenix will be used independently by the patients to perform rehabilitation sessions at home, under remote monitoring from the clinical team. A tailored rehabilitation program will be prescribed, based on the following principles:

STAGE 1 (Weeks 0-6) Open kinetic chain exercises without added resistance: lying, sitting and standing (with support) Strengthening of hip flexors and abductors (mainly) Ice pack application STAGE 2 (weeks 7-8) Open kinetic chain exercises with added resistance: lying, sitting (high chair) and standing (with progression to standing without support) Strengthening of hip flexors and abductors (mainly) Ice pack application after each session

Other Name: Smart Wearable Operative Rehabilitation Device
Active Comparator: Traditional home-based rehabilitation
Home-based rehabilitation sessions provided by a Physical Therapist
Other: Traditional home-based rehabilitation

Patients will perform 3 weekly rehabilitation sessions, with a duration of 1 hour, for 8 weeks, provided by a physical therapist. The rehabilitation program will respect the following principles:

STAGE 1 (Weeks 0-6) Soft tissue massage Active assisted mobilization of the hip joint to increase range of motion (avoiding internal rotation and adduction) Gait training with bilateral assistive devices Isometric exercises progressing to open chain, low-impact, concentric exercises with strengthening of hip abductors and flexors Ice pack application STAGE 2 (weeks 7-8) Soft tissue massage Gait training with progressive withdrawal of assistive devices Balance exercises with progression to one-leg support Open-chain strengthening exercises against resistance with progression to closed-chain exercises Ice pack application


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
