Morone 2016.

Methods	Study design: RCT Number of study arms: 2 Length of follow‐up: 3 months
Participants	Setting: Italy Number of participants: 38 Number analysed: 38 Number lost to follow‐up: 0 Sample: community‐dwelling Age (years): mean 68.93 (SD 4.18) Sex: 100% female Inclusion criteria: women; no or irregular physical or educational programmes for balance (or not performed for the last 2 years); age > 65 years; presence of a reduction in balance measured by the Berg Balance Scale (< 45); presence of bone loss (T score > 1.5 and < 2.5) as measured by central DEXA scan Exclusion criteria: presence of any orthopaedic, cardiovascular or oncologic pathology that could affect the balance ability; fracture/s in past year
Interventions	1. Group‐based balance training using Wii‐Fit: Wii Fit programme (balance, yoga, standing leg strengthening) supervised by a physiotherapist, 1‐hour session, 2 a week for 8 weeks 2. Group‐based balance training: conventional balance exercises (flexibility, lying muscle strengthening, balance on unstable balance platform, postural exercises in supine) supervised by a physiotherapist, 1‐hour session, 2 a week for 8 weeks
Outcomes	No outcomes included in review
Duration of the study	12 weeks
Adherence	Not reported
Notes	Source of funding: not reported Economic information: not reported No fall data in paper. Email communication about fall data, no response received. No fall data included in review
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "computer generated list"
Allocation concealment (selection bias)	Low risk	Quote: "allocation was concealed by covering each number of the list with an opaque adhesive label"
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Participants and personnel not blinded to group allocation. Effect of non‐blinding unclear
Blinding of outcome assessment (detection bias) Falls	Unclear risk	Falls were recorded using the same method in both groups. It is unclear whether assessors were blinded when collecting fall data
Blinding of outcome assessment (detection bias) Fractures	Unclear risk	Not applicable
Blinding of outcome assessment (detection bias) Hospital admission, medical attention and adverse events	Unclear risk	Not applicable
Blinding of outcome assessment (detection bias) Health related quality of life (self report)	High risk	Participants not blind to group allocation
Incomplete outcome data (attrition bias) Falls and fallers	High risk	No fall data available
Selective reporting (reporting bias)	High risk	Fall outcome prespecified but fall data not presented
Method of ascertaining falls (recall bias)	Unclear risk	Quote: "participants enrolled in both groups recorded in a specific diary the falls or events related to falls during the 3‐month follow‐up"
