Summary

This study will investigate the concurrent validity and intra-rater reliability of using smartphone in assessing joint position sense in patient with knee osteoarthritis.

Detailed description

Knee osteoarthritis is the most common arthritis. Such disease is complicated by many musculoskeletal dysfunction such as disturbed joint position sense, which impairs their ability to perform their regular daily activities. As rehabilitation should target impairment in function, it is essential that therapists assess joint sense during baseline and follow-up evaluation of patients to decide on needed therapeutic interventions. Joint position sense can be assessed by various methods such as motion tracking systems and the isokinetic dynamometer, yet these equipment are expensive and are not readily available at regular clinical settings. Smartphone has been introduced as an assessment tool in rehabilitation of musculoskeletal disorders. For the knee joint, smartphone has been validated for measuring range of motion and joint position sense in healthy population, yet it has never been validated in patients with knee osteoarthritis. Therefore, this study will investigate smartphone validity and reliability as an assessment tool of knee position sense in patients with knee osteoarthritis.

Conditions

• Knee Osteoarthritis

Interventions

Type	Name	Description
DEVICE	Smartphone application (Goniometer Pro )	Knee repositioning error will be measured simultaneously by smartphone and Biodex isokinetic dynamometer by a single blind assessor. All assessments will be done with eyes closed and repeated over two separate sessions, with one-week interval in-between. For active repositioning, the participant will actively extend the knee to reach a predetermined target position45° flexion at an angular velocity of 10°/sec. For passive knee repositioning, the isokinetic dynamometer will move the knee at 5°/s to a predetermined angle between 5° and 80° of flexion and the participant should stop the movement when the predetermined angle is reached.
