Brief Summary

Feasibility and acceptability randomized controlled trial exploring the use of a rocking chair after a total hip arthroplasty in adults who are aged 65 or older. Primary aims include its feasibility and acceptability; exploratory aims include the impact of rocking on pain, gastrointestinal effects, anxiety, ambulation, and additional healthcare visits.

Outcome Measures

Primary Outcomes (2)

• 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.

  From enrollment to 31-day follow-up

• 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).

  From enrollment to 31-day follow-up

Secondary Outcomes (6)

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

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

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

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

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

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

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

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

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

  From enrollment through 31-day follow-up
