OneStep technology is a smartphone application, utilizing smartphone sensors to provide ongoing gait diagnostics. In this longitudinal study, 50 consecutive patients with lower-extremity disability or chronic pain, will be using the One-Step App, downloaded to their personal smartphones, in parallel with the usual rehabilitation treatments, during a one-month period. Analyzed gait data from the App will be linked with clinical data collected by a team of experts, in order to evaluate the potential use of this App as an objective means to characterize and quantify patients' gait characteristics along the follow-up period, and to objectively assess the patients' adherence and compliance with the rehabilitation regime.
Background: Patient adherence is a crucial determinant of the rehabilitation process. After injury or surgery, many patients are given specific exercises to conduct unsupervised on their own to aid their recovery. Evidence suggests that noncompliance with the prescribed exercise regime is associated with poor rehabilitation outcomes. OneStep technology is a smartphone application (App), which uses smartphone sensors to provide ongoing gait diagnostics. Study Objectives: 1. To analyze gait-related parameters collected via the OneStep App in patients with lower extremity disability or chronic pain over a 4-week follow-up period during in-hospital physiotherapy sessions, self-exercises at home, and other daily activities, 2. To objectively assess the patients' adherence and compliance with the prescribed rehabilitation regime. For the purposes of this research, adherence refers to the quantity and frequency of completed home exercises, while compliance refers to the quality of meeting the physiotherapists' walking-related recommendations. 3. To assess gait parameters measured simultaneously on both feet, during standard walking-related tests, (performed under similar conditions on days 1, 14, 28, while using the OneStep App), for between and within-subject comparison. 4. To compare between patients' subjective self-reports on performed physiotherapy workouts at home, the physiotherapists' own subjective assessments on their patients' adherence and compliance, and the objective data collected using the OneStep App Methods: Fifty consecutive patients with lower-extremity disability or pain, will be using the One-Step App, downloaded to their personal smartphones, in parallel with the usual rehabilitation treatments, during a one-month period. The study participants will be asked to carry the smartphone with the preinstalled app on them at all times, specifically on their injured foot. All participants will also be required to undertake standard walking tests at the study initiation day (day 1) and on days 14 and 28 under similar conditions for between and within-subject comparison. Only during these tests will the subjects be using two smartphones preinstalled with the OneStep App, one attached to each leg, for a more accurate gait symmetry assessment. During these 3 sessions, the study participants, as well as their physiotherapists, will be asked to fill in the study questionnaires. Hypothesis: Data collected using the OneStep App will allow an accurate and informative follow-up on patients' adherence and compliance with the rehabilitation regime and assist the physiotherapists in improving the efficacy of the rehabilitation process.

OneStep technology is a smartphone application (app) utilizing smartphone sensors to provide ongoing gait diagnostics. The eligible study participants will be asked to download and install the app on their own smartphones and carry the smartphone in their front pants pocket at all times. The app will collect the required gait parameters but, will not present them (or any summary thereof) to the study participants or their physiotherapists, in order not to influence the rehabilitation plan.

Patients' Adherence with the Rehabilitation Regime
The patients' adherence with the rehabilitation regime refers to the quantity and frequency of completed home exercises, converted into an adherence score. Patients' self-reports and physiotherapists' own assessments on patients' adherence will be collected using newly developed questionnaires, while the objective data on patients' adherence will be collected using the OneStep App.
Time frame: One month of follow-up
Patients' Compliance with the Rehabilitation Regime
The patients' compliance with the rehabilitation regime refers to the quality of meeting the physiotherapists' walking-related recommendations, converted into a Compliance score. Patients' self-reports and physiotherapists' own assessments on patients' compliance will be collected using newly developed questionnaires, while the objective data on patients' compliance will be collected using the OneStep App.
Time frame: One month of follow-up
6-Minute Walk Test (6MWT)
It is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance (in meters) covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity. Each study subject will take this test 3 times: on days 1, 14, and 28 of the follow-up. During these tests, the study participants will be using 2 phones, each preinstalled with the OneStep application and placed on each foot for simultaneous data collection, for within and between-subject comparison.
Time frame: Assessed at days 1, 14 and 28 of the follow-up period
Timed Up and Go (TUG) Test
The test measures, in seconds, the time taken by an individual to stand up from a standard armchair walk a distance of 3 meters, turn, walk back to the chair, and sit down again. The subjects are asked to wear their regular footwear and use their customary walking aids. No physical assistance is given. The subjects start the test with their back against the chair, their arms resting on the armrests, and their walking aid at hand. They are instructed that on the word "go" they are to get up and walk at a comfortable and safe pace to a line on the floor 3 meters away, turn, return to the chair and sit down again. Each subject walks through the test once before being timed in order to become familiar with the test. Each subject will take this test 3 times (days 1, 14, and 28). During these tests, the study participants will be using 2 phones, each preinstalled with the OneStep app and placed on each foot for simultaneous data collection, for within and between-subject comparison.
Time frame: Assessed at days 1, 14 and 28 of the follow-up period
10-Meter Walk Test (10MWT)
The test is used to measure gait speed (in meters per second) of individuals with gait limitations. A 10-meter straight course will be marked at its beginning and end with tape on the floor. The study participant will be positioned 2 meters behind the first tape line. The subject will then be instructed to walk at a comfortable rate until one passes the second tape line. The timer is started when one crosses the first tape line and stopped when one crosses the second tape line. The 2-meter distances before and after the course serve to minimize the effect of acceleration and deceleration. The test is repeated 3 times and the average time is calculated. Each study subject will take these tests on 3 occasions (days 1, 14, and 28). During these tests, the study participants will be using 2 phones, each preinstalled with the OneStep application and placed on each foot for simultaneous data collection, for within and between-subject comparison.
