Primary outcomes

1. Number of participants that enroll and complete study assessed by Feasibility Participant Questionnaire (developed by investigators)

   Feasibility of active rocking post-operative measured by total number of participants enrolled, total percentage and number completing the study, and percent of missing data. A higher percent of missing data is a negative outcome.

   Time frame: From enrollment to 31-day follow-up

2. Total participants reporting acceptability of rocking or sitting as measured by Acceptability for Participants Questionnaire

   Acceptability of rocking or sitting after hip arthroplasty indicated by score on domains of affective, perceived effectiveness, intervention coherence, ethicality, burden, opportunity costs, self-efficacy likert scales from 1-4 (Not at all, a little, somewhat, very much). Scores from each domain are combined and summed to determine a single acceptability score (higher scores equate to higher acceptability of the intervention).

   Time frame: From enrollment to 31-day follow-up

Secondary outcomes

1. Total participants indicating Nausea using the PROMIS Scale v1.0 GI Nausea and Vomiting 4A

   Participants indicate Daily nausea assessment on 5-point Likert scale (never, rarely, sometimes, often, always). Higher scores indicate more Nausea.

   Time frame: From surgery (Day 1 of the study) to 31-day follow-up

2. Total participants reporting Gas/bloating via PROMIS v1.1 GI Gas and Bloating 13A

   Participants reporting Daily gas/bloating assessment on 5-point Likert scale (not at all, a little bit, somewhat, quite a bit, very much). Higher scores indicate more daily gas/bloating.

   Time frame: From surgery (Day 1 of the study) to end of 31-day follow-up

3. Total participants reporting Daily pain assessed by PROMIS v2.0 pain intensity 3A

   Participants reporting Daily pain assessment on 5-point likert scale (no pain, mild, moderate, severe, very severe). Higher scores equate to more daily pain experienced.

   Time frame: From surgery (Day 1 of the study) to end of 31-day follow-up

4. Total amount of participants' Daily Ambulation as measured using steps via activPAL4pro accelerometer

   The amount of participants' Daily ambulation will be assessed with the amount of steps taken per day using the triaxial accelerometer activPAL4pro. More steps per day equates to greater ambulation.

   Time frame: After surgery (Day 1 of the study) and up to 7 days post-surgery

5. Total amount of participants' Daily anxiety measured using the Anxiety subscale of the Neuro-QoL Hospital Anxiety and Depression Scale

   The participants will report their Daily anxiety assessment using the Anxiety subscale of the Neuro-QoL Hospital Anxiety and Depression Scale, which assesses self-reported fear, worry, tension, and nervousness and will be scored with a T-score with higher scores indicating more anxiety. The scores range from 0-3 (not at all, not often, sometimes, most of the time).

   Time frame: From enrollment through 31-day follow-up

6. Participants' self-reported Additional healthcare visits since their surgery, as assessed via phone call at 31-days post-surgery

   The total number of Additional healthcare visits will be assessed via phone call at 31-days post-surgery using the investigator-developed question: Have you been hospitalized since you have been discharged from your hip surgery?

   Time frame: From surgery (Day 1 of the study) until 31-day follow-up
