            CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS


  The following Quarterly Report on Form 10-Q contains various "forward
  looking statements" within the meaning of Federal securities laws.  These
  forward looking statements represent management's expectations or beliefs
  concerning future events, including statements regarding anticipated
  product introductions; changes in markets, customers and product pricing;
  expenditures for research and development; growth in revenue; and taxation
  levels.  When used in this Form 10-Q, the words "anticipate," "believe,"
  "expect," "estimate" and similar expressions are generally intended to
  identify forward-looking statements.  These and other forward looking
  statements made by the Company must be evaluated in the context of a
  number of factors that may affect the Company's financial condition and
  results of operations, including, but not limited to, the following:

  o    The Company's products are subject to reimbursement by private and
       public healthcare reimbursement agencies that impose limits on
       reimbursement and strict rules on applications for reimbursement.
       The Company is the subject of a whistleblower suit initiated by a
       former employee alleging improper filing of approximately 500,000
       Medicare claims, resulting in overpayments of more than $120,000,000.
       The Company has not yet been served with the complaint and has
       therefore submitted no response.  Resolution of that matter as well
       as changes in the rates, eligibility or requirements for
       reimbursement, or failure to comply with reimbursement requirements,
       could significantly impact earnings and financial condition.

  o    The Company acquired two businesses during the two previous fiscal
       years and a third in July 1999.  The Company may not be able to
       integrate acquired businesses as smoothly as it anticipated and may
       find issues with respect to acquired businesses of which it was
       unaware.

  o    Like many medical device companies, the Company has a large
       balance of uncollected receivables against which it maintains a
       reserve for doubtful accounts.  The size of the reserve is judgmental
       and depends upon a number of factors, including historical experience
       in collecting receivables.  If the Company cannot collect an amount
       of receivables that is consistent with historical collections, it
       might be required to charge off a portion of uncollected receivables
       in a single quarter, which could significantly impact earnings.

  o    The Company has incurred a significant amount of indebtedness to
       finance acquired businesses.  The interest expense on such
       indebtedness reduces earnings and could cause the Company to be short
       of cash if its operations do not meet expectations.

  o    The Company maintains significant amounts of inventory on
       consignment at clinics and for distribution to patients.  It may not
       be able to completely control losses of this inventory and, if
       inventory losses are not consistent with historical experience, it
       might be required to write off a portion of the carrying value of
       inventory, which could significantly impact earnings.

  o    The clinical effectiveness of the Company's electrotherapy
       products has periodically been challenged.  Publicity about the
       effectiveness of electrotherapy for pain relief or other clinical
       applications could negatively impact revenue and earnings.

  o    The Company formed a United Kingdom subsidiary in fiscal 1999 and
       acquired a Swiss company in the first quarter of fiscal 2000.  These
       operations may be more difficult to supervise, and may be subject to
       different economic influences than United States operations and they
       do subject the Company to more exposure from currency fluctuations.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31, 1999

1.   ACCOUNTING POLICIES

The amounts set forth in the preceding financial statements are unaudited as of
and for the periods ended December 31, 1999 and 1998 but, in the opinion of
management, reflect all adjustments (consisting only of normal recurring
adjustments) necessary for a fair statement of the results for the periods
presented.  Such results are not necessarily indicative of results for the full
year.  The significant accounting policies and certain financial information
which are normally included in financial statements prepared in accordance with
generally accepted accounting principles, but which are not required for interim
reporting purposes, have been omitted.  The accompanying financial statements of
the Company should be read in conjunction with the audited consolidated
financial statements for the year ended June 30, 1999, included in the Company's
Annual Report on Form 10-KSB.

In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, "Accounting for Derivative Instruments and Hedging Activities." This
statement requires that all derivatives be recognized at fair value in the
balance sheet and all changes in fair value be recognized currently in earnings
or deferred as a component of other comprehensive income, depending on the
intended use of the derivative, its resulting designation and its effectiveness.
The Company does not believe that the implementation of this statement will have
an effect on the Company's results of operations, cash flows or financial
position.

2.   BUSINESS COMBINATIONS

On July 19, 1999, the Company acquired all of the outstanding capital stock of
Compex SA, a Swiss-based medical products company, for cash of $10,747,967.  The
acquisition was financed principally with debt and provides for additional
contingent consideration of up to $2,000,000 based on performance over the
calendar years 1999 and 2000.  The purchase consideration exceeded the net fair
value of tangible assets by $9,721,566, of which $1,400,000 represented the
value of Compex's technology, $1,400,000 represented the value of its workforce
and the remaining $6,921,566 of which was assigned to goodwill.  The value of
these intangible assets will be amortized over various periods from five to
twenty years.  The allocations are preliminary, pending the outcome of certain
pre-acquisition tax contingencies. Additional consideration of approximately
$1,800,000 was earned for performance in 1999 and will be paid in March 2000.
That amount is included in goodwill as of December 31, 1999 and, effective
January 1, 2000, will be amortized accordingly.

Proforma operating results as if Compex SA had been acquired at the
beginning of fiscal 1999 are as follows:

On August 7, 1998, the Company acquired substantially all of the assets
(consisting primarily of finished goods inventory and receivables) of the
Homecare business unit of Henley Healthcare, Inc. ("Henley") for a purchase
price of $3,650,000 paid in cash at closing.  The cash paid was obtained from
existing funds and borrowings under the Company's bank line of credit, including
a $2,500,000 term loan payable over three years.

3.   NOTE PAYABLE AND LONG TERM DEBT

In conjunction with its acquisition of Compex SA, the Company entered into a new
$20,000,000 credit facility which provides for both term and revolving
borrowings at varying rates based either on the bank's prime rate or LIBOR.  The
initial term loan of $15,000,000 was used to fund the acquisition and repay the
balance of a mortgage note and a revolving loan provided under a credit facility
with another bank.

Borrowings under the new facility are secured by substantially all assets of the
Company other than those pledged as collateral on existing lease or mortgage
obligations.  The interest rate on the term loan was 8.36% at December 31, 1999
and the weighted average rate on borrowings under the revolving line of credit
was 8.70%.

The Company was in compliance with all financial covenants in its credit
agreement as of December 31, 1999 and for the period then ended.

4.   SEGMENT INFORMATION

Rehabilicare and its consolidated subsidiaries operate their business in one
reportable segment, the manufacture and distribution of electromedical pain
management and rehabilitation products.  The Company's chief operating decision
makers use consolidated results to make operating and strategic decisions.  Net
sales from the United States and foreign sources (primarily Europe) are as
follows:

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS


OVERVIEW

The Company designs, manufactures and distributes electromedical pain management
and rehabilitation products used for clinical, home health care, sports medicine
and occupational medicine applications.  The Company operates in one business
segment, distributing its products through sales to medical product dealers and
distributors and, in the United States, through direct rental or sale to
patients.  The latter approach involves placing electrotherapy units with
physicians, physical therapists and other health care providers who then refer
those units to patients after determining an appropriate treatment regimen.
Units are left on consignment with the health care providers for such referral.
The Company then bills the patient or the patient's insurance carrier directly
after being notified that a unit has been prescribed and provided to the
patient.  The Company takes responsibility for subsequent patient follow-up,
including additional months rental; sale of the unit, if appropriate; and sale
of additional supplies required for continued use of the electrotherapy units.
This distribution approach requires the Company to maintain significant
investments in inventories and receivables.


In the fiscal year ended June 30, 1998, the Company began implementation of a
strategy to increase its business through consolidation with other companies in
the pain management and rehabilitation markets.  The strategy began with the
merger with Staodyn, Inc. on March 17, 1998 in a transaction accounted for as a
pooling-of-interests.  On August 7, 1998, the Company acquired certain assets of
the Homecare division of Henley Healthcare, Inc. and the operations of that
business are included in the consolidated financial statements from that date
forward.  In January 1999, the Company established a majority-owned subsidiary,
Rehabilicare (UK), Ltd., near London, England.  Rehabilicare (UK) subsequently
acquired substantially all of the assets of the Company's former distributor in
the United Kingdom, effective February 1, 1999.  Its operations are included
from that date forward.  Sales to the distributor prior to that date are
included in net revenue.  Finally, on July 19, 1999, the Company acquired all of
the outstanding capital stock of Compex SA based in Lausanne, Switzerland.  Its
operations are included in the consolidated financial statements from the date
of acquisition.

</TABLE>



Revenue was $14,778,000 for the second quarter of fiscal 2000, a 36% increase
from $10,882,000 in the second quarter of fiscal 1999.  Revenue for the six
months ended December 31, 1999 increased 44% to $28,654,000 from $19,967,000 in
the first six months of fiscal 1999.  Compex accounted for $4,043,000 of revenue
for the second quarter and $7,019,000 for the first six months of fiscal 2000.
Other revenue for the second quarter of fiscal 2000 was essentially unchanged
from the second quarter of fiscal 1999 as the growth in patient referrals slowed
after several quarters of substantial growth reflecting the Company's
acquisition and consolidation strategy.  The primary reason for the increase in
such revenue for the six months ended December 31, 1999 was the full integration
of the former Staodyn and Rehabilicare sales organizations, a process which
started immediately after approval of the merger on March 17, 1998.

International business other than Compex was not significant as a percent of
total revenue in the second quarter and six month periods in both years.

  Gross profit was $10,671,000 or 72% of revenue in the second quarter of fiscal
  2000 and $19,948,000 or 70% of revenue for the first six months compared with
  $7,665,000 or 70% of revenue and $14,304,000 or 72%, respectively, in the
  comparable periods of fiscal 1999.  Cost of sales included a one-time charge
  of $645,000 in the first quarter of fiscal 2000 related to the step-up in
  basis of inventory recorded in connection with the Compex acquisition. Its
  inventory turns rapidly so the entire step-up flowed through the first
  quarter.  Without that charge, gross margin would have been 72% of revenue for
  the six months.  That rate is essentially unchanged from the rate for the
  fiscal year ended June 30, 1999 and is consistent with the Company's
  expectations.

  Selling, general and administrative expenses increased 26% to $7,677,000
  in the second quarter of fiscal 2000 from $6,075,000 in fiscal 1999 but
  decreased as a percentage of revenue from 56% to 52%.  For the six months
  ended December 31, 1999, those expenses increased 33% to $15,004,000 from
  $11,255,000 in fiscal 1999 but decreased as a percentage of revenue from
  56% to 52%.  Several factors contributed to those decreases.  Fiscal 1999
  included expenses of carrying the former Staodyn building in Longmont,
  Colorado which was sold in July 1999 and the costs of continuing
  operations in facilities formerly operated by Henley Healthcare which were
  closed during fiscal 1999.  The decrease also reflects the elimination of
  virtually all administrative costs associated with the former operations
  of Staodyn and Henley Healthcare and various economies of scale resulting
  from the Company's acquisition activity.

  Research and development expense increased about 67% for the second
  quarter and 33% for the six months but remained at approximately 2% of
  revenue from year to year.  The fiscal 2000 expenses include $98,000 and
  $185,000, respectively, incurred by Compex and, without that acquisition,
  those expenses would have decreased.  The Company substantially completed
  development of a new family of TENS products during fiscal 1999 and
  believes that the current expenditure level will be adequate to fund
  current product enhancement and development programs.

  Interest expense increased from $116,000 to $346,000 as a result of the
  acquisitions of the Henley Healthcare business in August 1998 and Compex
  in July 1999, both of which were financed with debt.

  Operating results for fiscal 2000 include a gain on the sale of the former
  Staodyn building in Longmont, Colorado in the amount of $1,076,000.  The
  Company exercised its option to purchase that building in the first
  quarter of fiscal 1999 and closed the purchase and immediate sale on July
  7, 1999.  Lease payments and operating costs associated with that building
  were expensed as incurred throughout fiscal 1999.

  The provision for income taxes was increased from 41% of income before
  taxes in the first quarter of fiscal 2000 to 42% for the six months ended
  December 31, 1999, compared with 38% and 41%, respectively, in the prior
  year.  The Company now operates in various countries in Europe as well as
  the United States.  Some countries have higher tax rates than the United
  States as well as different rules on the deductibility of certain expenses
  and the availability of certain credits for taxes paid to other
  jurisdictions.  The Company believes that 42% is a reasonable estimate of
  the effective rate for fiscal 2000 based on most recent estimates expected
  sources of revenue and expenses for entire year.

  As a result of all the above changes, net income increased from $774,000
  in the first quarter and $1,413,000 in the first six months of fiscal 1999
  to $1,232,000 and $2,666,000, respectively, in fiscal 2000.
  Diluted earnings per share increased from $.07 and $.12 to $.13 and $.25.
  Before the one time gain related to the building sale and the one time
  charge related to the Compex inventory step-up are eliminated, net income
  for the six months was $2,462,000 or $.23 per share.  Compex accounted for
  just over $.02 of that amount after deducting goodwill amortization and
  interest expense on acquisition debt from it's operating income.

  FINANCIAL CONDITION, LIQUIDITY, AND CAPITAL RESOURCES

  The Company generated cash of $1,426,000 in the first six months of fiscal
  2000 after using cash of $835,000 during the first six months of fiscal
  1999.  The most significant cash transaction during the period was the
  acquisition of Compex for $10,748,000, all of which was financed by
  additional bank borrowings.  As a part of that transaction, the Company
  consolidated its other bank debt into a new $20 million credit facility
  which provides for both term and revolving loans.  Net additional proceeds
  from borrowings related to the acquisition and other operating expenses
  was $11,891,000.  The purchase price for Compex will be increased by
  $1,800,000 based on certain operating results of Compex for the calendar
  year 1999.  Such payments will be made in March 2000.  An additional
  $200,000 could be paid in March 2001 based on certain operating results
  for calendar 2000.  The credit facility was designed to cover those
  amounts in the event cash flow from operations is not sufficient to fund
  them.

  The only other significant investing activity during the period was the
  purchase of $983,000 of property and equipment in the normal course of
  operation.

  As previously mentioned, the Company also generated net cash of $465,000
  from the sale of a building, net  of payment of the capitalized lease
  obligations.

  Cash was used to fund an increase in receivables of $2,408,000 during the
  first six months of fiscal 2000.  Compex receivables at the end of the
  quarter were $1,847,000 so without that acquisition, receivables would
  actually have increased by $561,000.  Managing receivables represents one
  of the biggest business challenges to the Company.  The process of
  determining what products will be reimbursed by third party payors and the
  amounts to be paid for those products is very complex and the
  reimbursement environment is constantly changing.  That risk is spread
  across many payors throughout the United States.  The determination of an
  appropriate reserve for uncollectible accounts at the end of each
  reporting period includes various factors including historical trends and
  relationships and experience with insurance companies or other third party
  payors.  The Company believes that the reserve at December 31, 1999 is
  adequate to cover future losses on its receivables based primarily on
  collection history and trends.  The provision for uncollectible accounts
  recorded in the income statement may fluctuate significantly from quarter
  to quarter as such trends change.  The reserve was 18.6% of receivables at
  December 31, 1999 compared to 22.2% at June 30, 1999.  That ratio will be
  favorably impacted in the future as a result of including receivables from
  Compex and Rehabilicare UK which are more traditional trade receivables
  and not dependent on third party payors.

  YEAR 2000 ISSUE

  The Company conducted an assessment of all its Year 2000 issues involving
  its technology systems over the last two years and successfully installed
  Year 2000 compliant versions of software from its two major vendors.  In
  addition, the Company analyzed and modified all supporting software,
  bringing all software into compliance.  Implementation was complete and
  Year 2000 compliant by December 31, 1999.

  The Company also completed its assessment of the Year 2000 issue
  surrounding its engineering and manufacturing product applications.  The
  Company's electrotherapy products are each controlled with
  electro-mechanical and microprocessor hardware mechanisms which do not
  have any time-dating requirements that would be affected by Year 2000.  In
  addition, these devices do not interface with other devices and therefore
  remain Year 2000 compliant.


                                       13




<PAGE>   14


  The Company also completed its study of its relationships with third
  parties whose failure to become Year 2000 compliant in a timely manner, if
  at all, could have an effect on the Company.  The Company circulated
  questionnaires to all of its significant vendors and customers with
  respect to such companies' Year 2000 compliance programs and status.  In
  addition, follow-up conversations were conducted with key customers and
  vendors.  The Company has completed that process

  External and internal costs specifically associated with modifying
  internal use software for Year 2000 compliance were expensed as incurred.
  Those costs were not material.  No significant, unexpected year 2000
  issues were encountered and additionally we do not anticipate any material
  adverse impact on future operations as a result of Year 2000 issues.

                          PART II - OTHER INFORMATION


   ITEM 1. LEGAL PROCEEDINGS

           On February 7, 2000, the Company reported that it had been advised by
           a reporter for The Tampa Tribune that it was the subject of a
           whistleblower suit filed in Tampa, Florida.  The Company still has
           not been served with the complaint but has obtained a copy of the
           suit from the United States District Court of the Middle District of
           Florida.  The suit was initiated by Elizabeth Mies, a former employee
           of Rehabilicare, on December 31, 1998, and the United States
           Government intervened as a coplaintiff under the False Claims Act on
           November 8, 1999.  It was under seal until January 21, 2000.

           The suit alleges that Rehabilicare, Staodyn, Inc. (a corporation
           acquired through a subsidiary of Rehabilicare in 1998), and Henley
           Healthcare, Inc. (from which Rehabilicare acquired certain assets of
           a division in 1998), improperly filed approximately 500,000 Medicare
           claims, that they were overpaid more than $120,000,000 on such claims
           and that the total statutory amount recoverable under the suit could
           be $15.4 billion.  The suit is based primarily on an allegation that
           all three companies submitted claims to the government on the basis
           of certificates of medical necessity faxed from physicians, rather
           than on signed originals, but also alleges that the companies altered
           those certificates and overbilled for accessories contained in a
           "standard medicare kit."

           Rehabilicare continues to be confused by the number of reimbursement
           payments the complaint alleges were received, noting that Medicare
           reimbursement constitutes only a small portion of the Company's
           revenues.

           As previously reported, the Company had completed a limited audit of
           Medicare files during the summer of 1999 and determined that many of
           the files were incomplete or incorrectly completed.  The audit found
           no evidence that the Company had submitted claims for which it did
           not provide product or services and no evidence of intentional
           wrongdoing.  The Company, through its outside legal counsel, had
           attempted several times to contact the United States Attorney's
           office in Florida, as well as the Durable Medical Equipment Regional
           Carriers that administer the Medicare reimbursement program, to
           discuss whether return of any of the reimbursements for the
           incomplete files was required.  There was no response to such
           requests.
