Despite the dramatic initial reduction in contracture, recurrence developed in a high proportion of patients over the study period. While initially effective, CCH may not provide durable contracture reduction. However, CCH remains a viable nonsurgical treatment for Dupuytren's disease.

Introduction:Annually, over 250,000 women are diagnosed with breast cancer with over one-third undergoing mastectomy and contemplating reconstruction. Surgical breast reconstructive options vary in post-operative recovery, yet with a paucity of objective data to inform women of their expected recovery after flap or implant-based reconstruction. As a result, patient decision-making is based primarily on surgeon preference and subjective data regarding perceived invasiveness of surgical options. This study aims to identify recovery outcomes of interest to breast cancer patients and to determine the feasibility of objectively measuring patient recovery after mastectomy and reconstruction using patient-worn actigraphy devices.Methods:Three survivorship focus groups for patients after mastectomy with and without reconstruction were used to identify recovery outcomes they considered relevant. Cloud storage systems and actigraphy devices were piloted to determine performance. Actigraphy devices were worn by patients peri-operatively to measure post-operative sleep quality and steps taken, normalized to individual patient pre-operative control data.Results:Focus groups identified sleep quality, return to activity (measurable with actigraphy), and driving as variables impacting surgical decision-making. We prospectively measured outcomes for four women undergoing immediate pre-pectoral tissue expander placement and four women undergoing immediate free flap reconstruction. Actigraphy data demonstrated an initial decrease in activity, increase in sleep variability and increased heart rate that approached the patients’ pre-operative normalized data as they recovered over time.Conclusions:These data demonstrate that actigraphy data would be of interest to patients making breast reconstruction decisions and that the data can be successfully collected to inform decision-making.

Background Currently, we lack objective measures to quantify outcomes in carpal tunnel syndrome. Instead, surgeons rely on patient-reported outcomes measures (PROMs) to assess the effect of carpal tunnel release (CTR). We assessed the validity and reliability of wearable activity monitors to objectively characterize the functional and sleep impact of CTR. We hypothesized that actigraphy could detect changes in sleep and activity and would demonstrate short-term impairment due the operative procedure. Methods This pilot, prospective, cohort study compared validated PROMS with actigraphy data obtained via wearable activity monitors (ActiGraph Link; ActiGraph Corp, Pensacola, Fla). Subjects completed baseline questionnaires and wore their device for 1 week preoperatively as a baseline. Subjects then underwent open CTR, wearing actigraphy devices for 4 weeks and completing questionnaires at 2 and 4 weeks postoperatively. Preintervention and postintervention data were compared using paired-sample t test. The Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire data were analyzed in accordance with published PROMIS scoring manuals and raw scores were converted to standardized T scores. Results Twenty subjects (5 males, 15 females) with moderate or severe carpal tunnel syndrome were enrolled. The mean age was 57.7 years. The PROMIS 29 average cumulative T score was 42.9 with average change of −0.072 preoperatively versus postoperatively. Average sleep disturbance T score was 38.9 preoperatively and 41.4 postoperatively. There was no statistically significant difference in T score in any domain. The mean actigraphy activity data demonstrated near immediate return to baseline activity. Actigraphy sleep data demonstrate improvement in sleep fragmentation and decreased duration of awakenings. Conclusions Overall, patient-generated data detected differences in sleep and activity preoperatively versus postoperatively and demonstrated only a short period of activity disruption after CTR, which may be used when counseling patients. These data support actigraphy as a viable adjunct to traditional PROMS to evaluate the impact of surgical intervention and therefore may be useful in the study of other diseases affecting the upper extremity.
