Use of the pedometer in the evaluation of the effects of rehabilitation treatment on deambulatory autonomy in patients with lower limb arthroplasty during hospital rehabilitation: long-term postoperative outcomes.

The paper reports only admission-to-discharge changes in one group that received the rehabilitation programme, so it cannot separate the programme's effect from time after surgery. All patients received the same multi-component rehabilitation programme, so the contribution of lower-limb kinesitherapy, walking training, balance training, bike training, or hydrokinesitherapy cannot be separated. Reliability and responsiveness were tested in only 30 patients, not all 156. The study did not have data from before surgery, so it cannot describe total change from the preoperative state. Patients older than 75 years and those with pain ≥7 on VAS, Barthel Index ≤50, obesity, cardiovascular or respiratory disease, infectious complications, or difficulty with physiotherapy were excluded, so findings may not apply to more disabled or medically complex patients.

The authors reported no funding, grants, equipment, financial benefits, or conflicts of interest.

Do not read the rise from 2,070 m per day to 3,100 m per day as proof that a single rehabilitation component caused it. The patients received lower-limb kinesitherapy, walking training, balance training, bike training, and hydrokinesitherapy together, and the study reports only admission-to-discharge changes in one group.
