Objective: To determine the effectiveness of balance training with Kinesthetic Ability Trainer 2000 (KAT 2000) in patients with peripheral neuropathic pain related balance disorder.

Methods: A total of 60 patients who developed peripheral neuropathic pain-related balance impairment in the chronic phase due to lumber disc herniation, lumber spondylosis and gonarthrosis were included into this randomized controlled prospective study and randomized into either balance exercises groups or KAT 2000 exercises groups. Balance exercises were given all patients in Group 1 (n=30). In addition to balance exercises, KAT 2000 balance exercises were given all patients in group 2 (n=30). All patients received 45-min individualized training session for three times a week for 4 weeks. Patients were evaluated according to pain, static and dynamic balance and quality of life (QoL).

Neuropathic pain was determined by the Douleur Neuropathique 4 (DN4) questionnaire. Pain severity was assessed by using a visual analogue scale (VAS). KAT 2000 was used to evaluate static and dynamic balance. Dynamic balance and mobility also was assessed using the Berg Balance Scale (BBS) and Time Up and Go (TUG) test. QoL was assessed by using Nottingham Health Profile (NHP). Patients were evaluated at baseline and the end of the 4-week exercise program.

Inclusion Criteria:

• DN4 scores ≥4 and moderately impaired balance with a score of 21-40 points on the Berg Balance Scale.

Exclusion Criteria:

• Who had history of previous cerebrovascular events; other neurological, musculoskeletal, inner ear or eye disease that may lead to impaired vision or standing balance.
