Author(s), Year	Country of the Study	Subjects	Psychological Construct Assessed	Intervention (If Applicable)	Study Design	Main Results
Bak et al., 2006 [56]	Germany	Sixty-four (48 m, 20 f; 67.3 age) consecutive patients were in treatment in an orthopaedic hospital.	QOL/HRQoL (SF-36), functional independence (FIM).	Yes (rehabilitation: kinesitherapy, prosthesis, occupational therapy-physiotherapy, educational programme, psychological or neuropsychological interventions).	Quantitative (cross-selection).	Both the SF-36 and the FIM were found to be sensitive enough to detect longitudinal changes in QOL/HRQoL and functional independence in the sample studied. The results should be interpreted with caution due to possible biases (floor and ceiling effects).
Horne et al., 2017 [40]	USA	Thirteen (58.3% f 60 age) participants had a LLA with a primary cause of peripheral vascular disease, diabetes, and/or end-stage renal disease at a large academic tertiary care.	Pain (SF-MPQ-2), depression, and anxiety (HADS), intervention (intervention journal card, intervention questionnaire, feasibility questionnaire).	Yes (desensitisation therapy).	Quantitative (pre-experimental repeated measure study).	This study provides some support for the use of tactile desensitisation in the acute postoperative period following lower limb amputation. Participants reported that the intervention helped to reduce pain.
